Effect of in-situ deposition of nano-calcium carbonate on the properties of anti-creasing cotton fabrics

Cotton fabrics exhibit excellent moisture absorption and breathability, which makes them comfortable to wear. However, they lack natural wrinkle resistance due to their poor anti-creasing performance and shape retention. Currently, anti-creasing finishing is widely applied to cotton fabrics; however, a contradiction exists between the anti-creasing effect and strength loss. To overcome this trade-off, a chemical deposition method was used to generate in-situ nano-calcium carbonate particles on anti-creasing cotton fibers. These particles effectively fill the micropores and microcracks in the anti-creasing cotton fibers, thereby improving the strength of the fabric. Scanning electron microscopy, wrinkle recovery angle, Fourier transform infrared spectroscopy and X-ray diffraction, and contact angle were used to characterize and analyze the changes in surface morphology, wrinkle resistance, chemical structure, and hydrophilicity of anti-creasing cotton fabrics before and after deposition treatment, respectively. Following nanoparticle deposition, the breaking strength of the anti-creasing cotton fabrics increased by approximately 11–14 %, whereas no significant changes were observed in their wrinkle recovery angle, chemical structure, and hydrophilicity. In addition, the crystallinity index increased after treatment and the washing durability of the deposited nanoparticles was excellent. This study demonstrates a method for overcoming the long-standing trade-off between the anti-creasing effect and strength loss and fills the gap in the field of non-destructive strength repair of anti-creasing cotton fabrics. The study findings provide important data for improving the strength of anti-creasing cotton fabrics. The proposed treatment method is inexpensive, simple, highly efficient, and harmless, and is expected to have bright prospects in future industrial applications.

Clean dyeing of cotton fabrics by cross-linking reactive dyes with fiber macromolecular chains

Increasing dye utilization, shortening the process and reducing the discharge of colored wastewater are the keys to clean dyeing and finishing of fabrics. In this study, we report a clean dyeing process. The process improved the dye utilization and achieved wrinkle-finishing and dyeing in the same bath by enhancing cross-linking of dyes with fiber macromolecular chains. It was observed by SEM that the cross-section of the dyed fibers showed round or oval shape, and the mid-cavities were reduced or even disappeared. The swelling rate of the fibers and cellulase degradation experiments showed that the dyes formed stable cross-linking structures with the macromolecular chains. Furthermore, differences in the structure of reactive dyes affected the optimal reaction conditions between the dyes and the fibers. Compared to conventional processes, the K/S, color fixation rate, and wrinkle recovery angle of dyed fabrics with different dyes were significantly improved. This illustrated the superiority of this process and the applicability of different structural dyes. Compared to traditional processes, the process saved 29.6 % of dyes and 16.7 % of alkalis. Importantly, the process could save 200 % of water, 9.5 kW h of energy consumption and 61.6 m3 of saturated steam. Ultimately, this process could save 7.22 $ of the cost of dyeing 1 kg of fabric. The concentration of dyes in the dyeing wastewater was significantly reduced. In summary, the clean process has good economic and environmental benefits.

Cotton–Cork Blended Fabric: An Innovative and Sustainable Apparel Textile for the Fashion Industry

Cotton is a preferred textile fiber for apparel textiles and is used primarily for summer wear. However, cotton has drawbacks, such as poor wrinkle resistance, and therefore, blends of cotton with other fibers have gained acceptance in the industry. In this study, a novel 90:10 cotton–cork blended fabric was studied for its physical and performance properties and benchmarked against a 100% cotton fabric. Fabric samples were analyzed to determine the wrinkle recovery angle, tenacity, abrasion resistance, shrinkage, CLO value, moisture absorption, and dyeability. The samples were further analyzed using SEM, DSC, and FTIR. The results showed significant differences between the two fabrics. Cotton–cork blended textile fabric had higher performance properties with the potential to be a viable, sustainable apparel textile.

Multifunctional ammonium polyphosphate coated cotton fabric for flame retardant, anti-wrinkle, ultraviolet protection and anti-bacterial

The multifunctional cotton fabrics, which were expected to become one of the most promising textile materials, gained much attention in the apparel market. In this work, the simultaneous coloration and finishing processes with natural dye were carried out to prepare the multifunctional cotton fabrics. The modification process using ammonium polyphosphate (APP) imparted the cotton fabric with numerous anionic sites along with flame retardant and anti-wrinkle properties. Subsequently, the implementation of coloration with berberine was to render the cotton fabric with elegant shade and anti-bacterial, ultraviolet (UV) protection performances. The obtained results revealed that the cotton fabric treated with APP could obtain deep shade. It was found that the limited oxygen index (LOI), wrinkle recovery angle (WRA), ultraviolet protection factor (UPF) and antibacterial efficiency of treated fabric were 46.4%, 252°, 193 and 99%, respectively. More importantly, the repeated laundering showed negligible influence on the flame retardant and anti-wrinkle performances. In addition, the anti-bacterial and UV protection performance of treated cotton fabric exhibited a slight decline even after 20 cycles of washing. Finally, the washing and rubbing fastness of obtained cotton fabric were also desirable.

Synthesis of castor oil/PEG as textile softener

New castor oil/polyethylene glycol (CAO/PEG) hybrids were synthesized by reacting of CAO with PEG 300, 600, 1000, 2000 or 4000, in presence of ammonium per sulfate (APS) as an initiator. The optimum conditions to synthesis such hybrids are: PEG/CAO weight ratio, 35%; APS/PEG weight ratio, 15%; reaction temperature, 80 °C; and reaction time, 60 min. Only the hybrids based on PEG 1000 and 2000 formed oil in water stable emulsions. Treating cotton fabric samples with easy care finishing formulation containing 40 g/L of the synthesized hybrids emulsions results in an enhancement in softness, tensile strength, whiteness index, and stiffness along with a reduction in nitrogen content, wrinkle recovery angle, and wettability properties of treated fabric, compared to that sample finished in absence of that emulsions. The chemical structure of the synthesized CAO/PEG1000 hybrid was confirmed via the FTIR and 1HNMRanalysis whereas the TEM analysis showed that the particles size of that hybrid emulsion is in the range of 27–105 nm. Moreover, such hybrid emulsion treated fabric surface was characterized via SEM and EDX analysis. Furthermore, treating dyed samples with the nominated hybrid emulsion improves the color strength of that samples but keeps the washing fastness, wet rubbing fastness as well as alkaline perspiration fastness of the dyed/finished samples unchanged. The wet rubbing fastness and alkaline perspiration fastness of all the dyed/finished samples were enhanced while the light fastness of such samples decreased.

Preparation of multifunctional cellulose macromolecule blended fabrics through internal and external synergy by N1, N6-bis (ethylene oxide-2-ylmethyl) hexane-1,6-diamine

With the diversification of people's demand for textile functions, the preparation of multifunctional fabrics is still a current research hotspot. In this study, the water-soluble epoxy compound N1, N6-bis(oxiran-2-ylmethyl) hexane-1,6-diamine (EH) was introduced into cellulose macromolecule blended fabrics (cotton/modal) by two-phase vaporization technique, resulting in excellent wrinkle, hydrophobicity, and certain UV protection effects. It could be observed by electron microscopy that EH formed a polymer film on the fiber surface. In addition, the results of EDS scans and fiber swelling rate tests showed that EH was uniformly distributed and formed a cross-linked structure in the amorphous zones inside the fibers. Compared with the control fabrics, the wrinkle recovery angle of the EH-treated fabric was increased by 39.7 %. The fabrics could reach a contact angle of 136.9°, providing excellent hydrophobic effect. In addition, the fabrics achieved certain UV protection effects (UPF of 50+). The EH-treated fabrics were less stabilized in strong acid and alkali conditions, but exhibited greater durability in other environments. In summary, the internal and external synergistic effects of EH in forming polymer films on the fibers surface and internal cross-linking structures provided a cleaner, simple, and feasible method for the preparation of multifunctional cellulose macromolecule fibers textiles.

Highly efficient cross-linking of reactive dyes in the amorphous zones of cotton fabric to simultaneously improve color and wrinkle properties

Dyeing and wrinkle-finishing of cotton fabric is generally achieved through two steps, which consumes a lot of energy and generates a lot of colored wastewaters. In this study, we report an energy-saving and cost-reducing dyeing process that enhanced the cross-linking degree of double reactive group dye in the amorphous zone of cotton fabric, which in turn improved the wrinkle resistance of cotton fabric as well as the utilization of the dye. Compared with the traditional dyeing processes, the method could improve K/S values by 69.7%, dye fixation by 22.4%, and wrinkle recovery angle by 21.5% for dyed cotton fabric. The wrinkle recovery angle of the dyed cotton fabric increased with the increase of cross-linking degree. The cross-section of cotton fibers changed from a flattened girdle shape to an elliptical or rounded shape, and the mid-cavity structure became smaller or even disappeared. In addition, the cross-linked structures could hinder the degradation of fiber macromolecular chains by cellulases. This meant that the better the wrinkle resistance of the dyed cotton fabric, the lower the glucose content in the degradation solution. Compared with the conventional dyeing processes, this dyeing method could be saved 36.5% of dyes and 28.4% of alkali for per 1 kg of cotton fabric, and the cost could be saved by 56.1%. The dye concentration in the waste water was reduced by 43.2%. This method had certain advantages in terms of economic and environmental.

Cetylpyridinium chloride cationic finishing improves the dyeing and antibacterial properties of madder dyed cotton

AbstractIn this work, after cationic pretreatment of cotton fabric with cetylpyridinium chloride (CPC), the compound of citric acid (CA) and succinic acid (SUA) were used as crosslinking agents to dye cotton fabrics with natural madder dye to improve the dyeing and antibacterial properties and realise the multifunctional finishing of cotton fabric. The effects of mordant dyeing, CA + SUA crosslinked dyeing, and CPC/CA + SUA crosslinked dyeing on the microstructure and properties of cotton fabrics were compared. The dyeing by the three processes occurred primarily in the amorphous zone of the fibres, and all kept the original crystalline form of the cotton. CA + SUA crosslinked dyeing and CPC/CA + SUA crosslinked dyeing increased the thermal stability of the cotton fabric. CPC/CA + SUA crosslinked dyed cotton obtained excellent dyeing results with the colour depth value (K/S) of 12.3 and rubbing fastness and washing fastness of levels 4–5, and the levelness and dye permeability were acceptable. Furthermore, the antibacterial rate against Escherichia coli and Staphylococcus aureus reached 99.99%, and the ultraviolet protection factor (UPF) reached 50+. Moreover, the wrinkle recovery angle (WRA) increased by 55% compared with raw cotton. This showed that CPC/CA + SUA crosslinked dyed cotton had excellent antibacterial, anti‐ultraviolet, and anti‐wrinkle performances.

Vinylated Modification of Biophytic Acid and Flame-Retardant/Crease-Proofing Finishing of Cotton Fabrics via In Situ Copolymerization

The vinyl phytic acid (GPA) was prepared using biophytic acid (PA) and glycidyl methacrylate (GMA), in which double bonds were introduced into the phytic acid molecule to increase the active groups in the phytic acid molecule. Furthermore, itaconic acid (IA) containing two unsaturated double bonds and GPA was polymerized in situ and crosslinked on the surface of cotton fabrics, and flame retardant and crease-proofed fabrics were obtained. The effects of GPA, IA, and the initiator on the flame-retardant and crease-proofing properties of the fabrics were analyzed by a single-factor and double-dip double-nip experiment. A flame-retardant and wrinkle-resistant fabric was obtained when the limiting oxygen index (LOI) and wrinkle recovery angle (WRA) were 28% and 270°, respectively. During combustion, the thermal properties of the fabrics changed; typically, the extrapolated initial temperature (Te) decreased, and moisture release increased. After burning, the fabrics had good shape retention, and the carbon residue content increased to 48%, which effectively inhibited or slowed down the combustion and heat release of the textiles. However, the whiteness, mechanical properties, and washability of the products need to be further improved.

Environmentally benign flame-retardant cotton fabric with superior anti-wrinkle performance and restorable flame retardancy

Flammability and wrinkling are major defects that enormously restrict its application of cotton fabric in daily life. Herein, a N-heterocyclic compound with ammonium phosphate ester groups (PNH) was synthesized and served as a cross-linking agent to simultaneously enhance the flame-retardant and anti-wrinkle properties of cotton fabric. Fabric treated by 20 wt% PNH solution (CT/PNH20) possessed a wrinkle recovery angle of 234.8° and an LOI value of 42.7 %. It still self-extinguished during combustion even after 50 washing times, and the deterioration in flame retardancy mainly resulted from the formation of sodium phosphates during washing. Its LOI value after 50 washing times restored to 37.8 % from 27.5 % by a facile ion exchange strategy, revealing remarkable flame-retardant restorability. This work provides new insights into simultaneously enhancing the flame-retardant, anti-wrinkle performances of cotton fabric and restoring the flame retardancy of treated fabric after washing via facile and eco-friendly approaches. • A N-heterocyclic compound with multiple reactive groups (PNH) was synthesized. • PNH conferred superior flame-retardant and anti-wrinkle properties to cotton fabric. • Treated cotton fabric showed remarkable flame-retardant durability and restorability.

Robust superhydrophobic and wrinkle-recovering fabric based on shape memory epoxy

Self-cleaning and crease-recovering are of special significance to increase the value of the fabrics. To endow the common cotton fabric with such multi-functionalities, a composite coating of shape memory epoxy resin / silica nanoparticles was proposed herein. The so-finished fabric exhibited good superhydrophobic nature with contact angle of 155.8° and crease self-restoring property with a heating wrinkle recovery angle of 144.1°. Moreover, the so-finished fabric possessed excellent stability under mechanical abrasion against sand paper, and ultrasonic vibration in ethanol.

Developing the functional cotton fabric with N-halamine antibacterial structure based on DA/PEI

In this study, functional coatings with N-halamine structure were formed on cotton fabrics by dopamine (DA) auto-deposition and DA/Polyethyleneimine (PEI) covalent co-deposition, respectively. SEM、UV-Vis and XPS had confirmed the deposition of DA and DA/ polydopamine (PDA) on the cotton fabrics. When the mass ratio of DA/PEI was 1:1.5, a uniform functional coating was formed. XRD had indicated that the coating and the oxidative sodium hypochlorite solution did not affect the crystal structure of cellulose. The DA/PEI co-deposited modified cotton fabric had excellent antibacterial property after chlorination, and the inactivation rate against E coli and S aureus could reach 100% with a contact time of 30 min. In vitro cell cytocompatibility studies demonstrated that the DA/PEI co-deposited modified cotton fabric has good biocompatibility. The functional coating on the cotton fabric remained stable after 50 washing cycles. The UPF values and the wrinkle recovery angle (WRA) tests showed that the DA/PEI co-deposited coating imparted great durable press and UV protective properties to the cotton fabric. The breaking strength loss rate of the modified cotton fabrics after chlorination was about 20%, which had little effect on the wearing property.

Study on the cross-linking process of carboxylated polyaldehyde sucrose as an anti-wrinkle finishing agent for cotton fabric

Sucrose was oxidized in a two-step oxidation reaction catalyzed by 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)-laccase and sodium periodate (NaIO4). To generate carboxylated polyaldehyde sucrose (openSu) containing multiple aldehyde and carboxyl groups. The amount of TEMPO and laccase used, as well as the temperature and reaction time were optimized for the oxidation reaction. The successful combination of aldehyde and carboxyl groups of openSu with cellulose was achieved by changing the composition, ratio of the catalyst and the curing conditions. Thereafter, we analyzed the structural characteristics of openSu as well as the aldehyde and carboxyl group content using nuclear magnetic resonance carbon spectroscopy (13C NMR). We found that the optimal finishing conditions were a mixture of magnesium chloride and sodium hypophosphite at a mass concentration ratio of 16 g/L:4 g/L, and curing at 150 °C for 3 min followed by curing at 180 °C for 2 min. There was significant improvement in the anti-wrinkle performance of the openSu-finished fabric, with a wrinkle recovery angle of 258°, whiteness index of 72.1, and a tensile strength rate of more than 65%. We also studied the covalent crosslinking mechanism between openSu and the cotton fabrics.

Performance Enhancement of Self-Cleaning Cotton Fabric with ZnO NPs and Dicarboxylic Acids

In this paper, we explore the self-cleaning and washing durability of green-prepared ZnO NPs combined with cotton fabrics. Honeysuckle extract was used to prepare ZnO NPs with an average particle size of 15.3 nm. Cotton fabrics were then treated with oxalic acid (OA), tartaric acid (TA), and succinic acid (SA) as cross-linking agents, sodium hypophosphite as a catalyst, and after that, the ZnO NPs were applied to the cross-linked cotton fabrics by the padding to prepare the self-cleaning cotton fabrics. The morphology and structure of the fabric samples were characterized using FTIR, scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDS), and XRD. The optical properties of the cotton fabric samples were discussed by UV-vis diffuse reflectance spectrum, and the self-cleaning performance, wrinkle recovery angle and ultraviolet protection performance of the cotton fabric samples were analyzed. The results showed that the carboxyl groups of TA, OA, and SA were esterified with hydroxyl groups of the cotton fiber and formed a film on the surface of the cotton fabrics. ZnO NPs were successfully loaded onto the cotton fabrics by strong electrostatic interaction, causing the improvement of the washing resistance of the cross-linked fabrics. In addition, compared with uncross-linked fabrics, the wrinkle recovery performance of the cross-linked fabrics had also been greatly improved, and the UV protection factor reached 50+, thus obtaining an excellent self-cleaning, multifunctional cotton-based textile with anti-wrinkle and anti-ultraviolet properties.

One-step Easy-Care and Softening Finishing of Knitted Cotton Fabric

Cotton is a natural fiber which has a tendency to wrinkle due to its perfect absorbancy properties. Nowadays, people prefer to use easy-care fabrics, so a lot of research has been done about this issue since the 1940s. In most researches, carboxymethylation and causticization processes are applied to bleached or semi-bleached cotton fabric, yet in this project dyed cotton fabric is used. Factories are applying resin finishing which is expensive, decreases fabric strength, increases stiffness of fabric so handle affected poorly from this application. Formaldehyde-based chemistries were used for increase wrinkle recovery performance of fabrics before, but formaldehyde is a suspicious carcinogenic chemical very dangerous for human health. Currently, DMDHEU and BTCA are the most well-known crosslinking chemical materials in wrinkle-free finishing, but in this study, cationic silicone softener was used as the crosslinker, and its effect on crease resistance was investigated. In the study, after the dyed cotton fabrics were given anionic character by applying causticization with Sodium Hydroxide (NaOH) and carboxymethylation processes with Sodium Chloroacetate (SCA), respectively, three different concentrations of cationic silicone were applied with the pad-dry-cure method for the cross-linking process. Then, wrinkle recovery angle (WRA) measurements were performed on crosslinked cotton fabrics in order to understand the interaction between causticization and crosslinking; and determine the better causticization and crosslinking levels that offer highest fabric performance. Experimental results showed that the best WRA results were observed at 10% NaOH, 0.5M SCA. Same SCA and softener concentration with 15% NaOH has adverse effect compared to 5% and 10% NaOH levels.

Ethylene glycol diglycidyl ether applied to crosslinking dyeing of cotton fabric with madder dye

AbstractCotton fabric dyed with natural madder dye exhibits poor dyeing properties. Although mordant improves the dyeing property of cotton fabric, it changes the madder dye colour tonality (the hue angle). In this study, ethylene glycol diglycidyl ether (EGDE) was used as a crosslinking agent to dye cotton fabrics with natural madder dye and improve the surface colour depth (K/S) and colour fastness. The molecular structure, crystal structure and surface morphology of crosslinked dyed cotton were analysed using Fourier Transform–infrared spectroscopy, X‐ray diffractometry and scanning electron microscopy, respectively. The results showed that crosslinked dyed cotton fabric had two different ether bonds, and that crosslinked dyeing mainly occurred in the amorphous area. Compared with direct dyed cotton fabric, the hue angle (h°) of crosslinked dyed cotton fabric did not undergo an obvious change, K/S increased by 5, and the rubbing fastness, washing fastness and light fastness increased by 2‐3 levels, indicating that the dyeing property of cotton fabric with natural madder dye could be improved by using EGDE as a crosslinking agent. Compared with raw cotton fabric, the bending length of crosslinked dyed cotton fabric was reduced by 2.28 cm, the wrinkle recovery angle increased by 80.7° and the ultraviolet protection factor value was more than 40, indicating that crosslinked dyed cotton fabric had great softness, wrinkle resistance and excellent ultraviolet resistance. In addition, the water contact angle of the cotton fabric only changed slightly after crosslinking dyeing, and the crosslinked dyed cotton fabric still had good hydrophilicity. Therefore, EGDE was a viable crosslinking agent for cotton fabric with madder dye.

Preparation of multiple-reactive-site and flexible crosslinking agent with transaconitic acid and acrylic acid and its application for three-dimensional crosslinking of cellulose

A novel multiple-reactive-site crosslinking agent, P(TAA‒AA), was developed from transaconitic acid and acrylic acid in this study. Cotton fabrics with durable wrinkle-resistant properties were obtained by crosslinking with P(TAA‒AA), which benefited from the multifunctional carboxyl groups of crosslinking agents and the three-dimensional crosslinking inside cotton fibers. The wrinkle-resistant properties of P(TAA‒AA)-modified fabrics were evaluated and compared with those of other polycarboxylic acid-treated fabrics, and the P(TAA‒AA)-modified fabrics showed a wrinkle recovery angle of 262° as high as the 1,2,3,4-butanetetracarboxylic acid-modified fabrics while maintaining nearly two-fold higher tearing strength retention (62.9%), and they showed a much higher value of whiteness index than the citric acid-modified fabrics. This demonstrated that the obtained P(TAA‒AA) is an ideal polycarboxylic acid already known to date simultaneously to realize the high wrinkle recovery angle and high tearing strength retention for treated cotton fabrics. The Raman depth mapping images and the scanning electron microscope images of P(TAA‒AA)-modified samples indicated that P(TAA‒AA) molecules can diffuse into the amorphous regions of the cellulose fibers and form crosslinking bridges between cellulose chains. The multiple reactive carboxyl groups in P(TAA‒AA) may form three or more ester bonds between the P(TAA‒AA) molecule and different cellulose chains, which were regarded as the main contribution to the high crosslinking effectiveness of the P(TAA‒AA)-modified fabrics.

ENHANCING UV PROTECTION AND HYDROPHOBIC ABILITIES OF POLYESTER TEXTILES BY NOVEL SURFACE MODIFICATION TECHNIQUES

In this study, water vapour permeability, wrinkle recovery, UV protection and contact angle properties of ion implanted Polyester (PES) fabrics were investigated. In order to achieve this goal; our Metal Vapor Vacuum Arc (MEVVA) source implanted Pb, Ag, Ag+N, Ti+O and Cr+O to the PES fabrics with 5x1016 ion/cm2 and 30 kV acceleration voltage. The test results were compared with unimplanted PES fabric. The results indicated that UV Protection and contact angle values increased significantly and also almost no change observed at water vapour permeability and wrinkle recovery. These results also varied on severly with different ion species.

Amphiphilic alginate stabilized UV-curable polyurethane acrylate as a surface coating to improve the anti-wrinkle performance of cotton fabrics

In this paper, a reactive amphiphilic alginate was prepared by an Ugi reaction using 4,4′-diaminostilbene-2,2′-disulfonic acid and its structure was analyzed by FT-IR and 1H NMR measurement. Subsequently, it was utilized as emulsifier to prepare polyurethane acrylate (PUA) emulsion and the colloidal properties including zeta potential, droplet size distribution and stability were evaluated. The results showed that the PUA emulsion by this modified alginate had better colloidal stability than that by original one. Finally, stable PUA emulsion was used for surface treatment of cotton fabrics in a UV curing process to improve their anti-wrinkle performance. By measuring the wrinkle recovery angle, it was found the anti-wrinkle properties of cotton fabrics were significantly improved with the increase in the amount of modified alginate. In addition, this anti-wrinkle finishing method was found to have many advantages such as low temperature, low yellowing as well as high washing resistance.

Non-Formaldehyde Wrinkle Resistant Finish for Linen

ABSTRACT Linen, even though it has a beautiful drape, is highly susceptible to wrinkles, especially under high humidity. A study was conducted to develop a wrinkle-resistant finish using a combination of three carboxylic acids at various pΗ and concentrations on linen fabric. The treated fabric was analyzed to determine the effect on wrinkle recovery angle, wrinkle recovery appearance rating, and carboxyl group content. The amount of finish application on the fabric was governed by percent weight gain of treated samples, carboxyl ‘n’ group content, wrinkle recovery angle, and wrinkle recovery appearance rating. Furthermore, a reduction in the availability of free OH groups in the linen cellulosic chains was studied using FTIR spectroscopic analysis to qualitatively analyze the attachment of acid groups to the monomers of the fiber polymeric chain. The results showed significant wrinkle resistance for treated samples.
