The influence of formaldehyde removal finishing on fogging characteristics and properties of polyester fabrics

The air quality in the vehicle indoor microenvironment has been of particular public concern because of its harmful effect on the human body. The volatile and semivolatile organic compounds in the vehicle indoor air can condense onto the cooler surface of the windshield, potentially creating a visibility and safety problem for the driver. This paper aimed to prepare multifunctional polyester fabrics with formaldehyde removal properties and low fogging degrees. The formaldehyde removal finishing of polyester fabrics was carried out with different formaldehyde removal agents using the pad-dry-cure method. The influence of formaldehyde removal finishing on the formaldehyde removal efficiency, fogging degree and some related performances of polyester fabrics are studied. The results show that the fogging degree increased (lower than standard values: 2 mg) after finishing with formaldehyde removal agents FK-1, FK-2, FK-3, FK-5, and FK-6. The formaldehyde removal rate of polyester fabrics after finishing was above 75%, and the performances of water repellence, softening behavior, color fastness were maintained. Our approach provides an easy method for use in vehicle indoor air purification systems and the finished fabrics can be applied to various applications such as home, automobile, office, and industry.

Study on Bonding Properties of Polyester Fabric and Nitrile/Chlorinated Butyl Rubber

In this paper, the composite material of polyester fabric and nitrile/chlorobutyl bonded with rubber is prepared by molding and hot vulcanization process. The influence of various polyester fabric treatment methods on the bonding ability is analyzed, and the change of peel strength when changing the blending ratio of rubber is explored. The results show that when the blending rubber is mainly NBR, the bonding ability with fabric is better. The adhesive properties of RFL impregnated polyester fabric and nitrile/chlorinated butyl rubber are higher than those of plasma treated and cotton fiber polyester blended fabric. The adhesion between rubber and polyester fabric can be improved by brushing kemlock adhesive on the fabric surface and adding RA /RS adhesive to the rubber formula.

Self-cleaning Property of Polyester Fabrics Finished with 3DOM TiO2

Three-dimensionally ordered macroporous titanium dioxide (3DOM TiO2) was prepared by a sol-gel method using poly(methyl methacrylate) as a template. The synthesized 3DOM TiO2 was finished on poly(ethylene terephthalate) and poly(lactic acid) fabrics by a pad-dry-cure method to enhance self-cleaning properties. Discoloration of curcumin, carmoisine and methylene blue stains on finished fabrics under UVA irradiation was examined to evaluate its self-cleaning abilities. The results showed that 3DOM TiO2 on the finished fabrics could diminish the stains in a higher degree as compared to the unfinished fabrics and fabrics finished with TiO2 nanoparticles. Dyeing properties of polyester fabrics with C.I. Disperse Red 60 were slightly affected by 3DOM TiO2. Color strength (K/S) and wash fastness of the 3DOM TiO2 finished fabrics were a little lower than the unfinished counterparts.

Multi-response optimization in impregnation of chitosan nanoparticles on polyester fabric

A Taguchi design was employed to optimize the recipe for in vitro antibacterial activity of polyester fabric treated with chitosan nanoparticles (CNPs), which were prepared using sodium tripolyphosphate as cross-linker under ionic gelation method. The CNPs treated polyester fabric with recommended recipe under Taguchi design showed about 5 mm zone of inhibition against E. coli and 5.5 mm against S. aureus. Scanning electron microscopy installed with an energy-dispersive x-ray detector was used to observe the morphology and presence of CNPs on the treated fabric. Based on statistical design, it was found that optimum process conditions were 15 g/l of CNPs, 90 g/l of cross-linker and 140 °C curing temperature. Analysis of variation indicated that the concentration of CNPs and cross-linker significantly affected the antibacterial properties of polyester fabric. Finally, a validation run confirmed the authenticity of proposed recipe. The polyester fabric showed good antibacterial activity with minimum loss of its inherent textile properties.

Investigation of the relation between surface roughness and friction properties of polyester fabrics after abrasion

This paper focused on the investigation of surface roughness and friction properties of polyester fabrics after abrasion. Experiments were performed on polyester woven fabrics produced from the same yarns in warp and weft directions but with different constructional properties. Surface roughness parameters of amplitude, spacing and hybrid, along with static and kinetic coefficients of friction were measured before and after multiple abrasion cycles. Abrasion was used in order to change the surface characteristic (peak and valley heights and depths and their distributions) in such a way by forming ruptured fiber ends under the control of abrasion. Measurements were made along warp, weft, and diagonal directions. The results showed that roughness parameters decreased numerically as abrasion cycles increased and as ruptured fiber ends formed. Static and kinetic coefficients of friction changed in different manners when measurements were performed along warp and weft directions. It was concluded that initial and resultant peak heights and valley depths together with their distribution on fabric surface govern roughness and friction properties of surfaces in opposite ways. Roughness parameters of skewness and kurtosis could be further considered in the research of friction properties of textile surfaces.

Investigation of Effect of Cellulosic Coating on the Some Properties of Polyester Fabric

Due to the inherent hydrophobic nature of Polyester fibers, fabrics formed entirely from Polyester fibers exhibit relatively poor moisture absorption and release properties introduce an uncomfortable condition to the wearer. The present study focuses on adding enhanced and durable hydrophobicity properties to Polyester fabrics, through coated using a cellulose solvent of NaOH/urea/thiourea aqueous solution at 8/8/6.5 compositions. Aqueous NaOH/urea/thiourea solution as non-derivatizing solvent broke the intra- and inter-molecular hydrogen bonding of cellulose and prevented the approach toward each other of the cellulose molecules, leading to the salvation of cellulose which the hydrophilic properties imparted to the fabric. The effect of percentage of cellulose solution coating has been studied on some physical properties such as fabric wettability, water wicking, stiffness, and air permeability, as well as the method of application of the cellulose coating. The surface characterization of the coated Polyester fabric is performed using FTIR and SEM. The results relate to coated Polyester fabric demonstrated enhanced and durable hydrophobicity and rewetting properties due to hydrophilic properties imparted to these substrates

Effect of sample layer numbers and fabric constructional parameters on colour strength, colour difference and colour matching properties of polyester woven fabrics

This paper focused on the effect of different fabric layer numbers on colour strength (K/S), colour difference () and colour matching properties of polyester fabrics woven with different constructional parameters. Colour strength and colour difference measurements were conducted on the dyed fabric samples at six (1, 2, 3, 4, 8 and 16) different fabric layers. Polyester fabrics having different constructional parameters were used and the fabrics differed from each other by their weft yarn filament fineness (fibre count), weft yarn densities and weave patterns in the experimental subgroups. Warp yarn type and count, warp density and warp yarn twist were the same in the subgroups. Colour strength, colour difference and colour matching properties were discussed depending on constructional parameters and fabric layer numbers. Colour difference values of the fabrics decreased as layer numbers increased. However, they increased as fibres in fabric structure became finer, as weft densities decreased and as weave patterns differed from plain to sateen. Colour matching between different constructed polyester fabrics became easier when plain patterns and high weft densities were used, i.e. when compactness increased. Usage of finer filament yarns caused fabric compactness to increase but colour matching became more difficult under certain circumstances. Colour matching became easier with increasing compactness but usage of different filament fineness affected the ease of matching depending on fabric constructional properties.

Effect of Argon Plasma Treatment Variables on Wettability and Antibacterial Properties of Polyester Fabrics

In this research work, the effect of argon plasma treatment variables on the comfort and antibacterial properties of polyester fabric has been investigated. The SEM micrographs and FTIR analysis confirms the modification of fabric surface. The Box–Behnken design was used for the optimization of plasma process variables and to evaluate the effects and interactions of the process variables, i.e. operating power, treatment time and distance between the electrodes on the characteristics of polyester fabrics. The optimum conditions of operating power 600 W, treatment time 30 s, and the distance between the electrodes of 2.8 mm was arrived using numerical prediction tool in Design-Expert software. The plasma treated polyester fabrics showed better fabric characteristics particularly in terms of water vapour permeability, wickability and antibacterial activity compared to untreated fabrics, which confirms that the modified structure of polyester fabric.

Flame-Retardant Properties of Polyester Fabrics Reinforced Phenolic Resin Modified with Silazanes Composites

Phenolic resin modified with methylvinylcyclosilazanes (MVSZ) were prepared and their flame-retardant properties were investigated, and results exhibited that the Limited Oxygen Index (LOI) values increased with the content increasing of MVSZ, and the LOI reach to 40.8, when the content of MVSZ was 26.0%. The flame-retardant and mechanical properties of polyester fabrics reinforced phenolic resin modified with silazanes (PFMS) composites were measured, the results indicated that the LOI and flexural strength were enhanced compared with those of phenolic resins composites.

Sol-gel synthesis of organic-inorganic hybrid materials comprising SnO2, silica, and thiazole dyes on polyester fabrics for water repellent and warmth retaining finishing

In this work, an inorganic/organic hybrid material composed of tin dioxide, silica, and heteroaryl 2-aminothiazole was derived. Heteroaryl 2-aminothiazole, which acts as the coupling component, was synthesized based on a previously published method and coupled with p-nitroaniline, which is the diazonium component, to yield the heteroaryl thiazole azo dyes. Alternatively, tin dioxide/silica/thiazole dye hybrid materials were prepared by heating tetrahydrofuran solutions containing these thiazole dyes with various amounts of tin chloride and tetraethoxysilane to promote hydrolytic polycondensation via the sol-gel method. The structure of these hybrid tin dioxide/silica/thiazole dye materials was characterized by Fourier transform infrared (FT-IR) analysis. The uniform dyeing of the polyester fabric revealed by the scanning electron microscope images confirmed the reaction of the hybrid materials with the polyester fabrics. The results of the characterization of the warmth retention, color strength, water repellency, and air permeability of the polyester fabric dyed with the tin dioxide/silica/thiazole dye hybrid materials indicated that the sol-gel hybrid-material finishing agents significantly improve the properties of polyester fabric.

Synthesis of Oktakis (tetramethylammonium)-T8-silisesquioxane and its Application in Polyester Fabric Functional Modification

To improve the properties of polyester fabric, the oktakis (tetra-methyl-ammonium)-T8-silisesquioxane (TMA-POSS) is applied to modify polyester fabric. TMA-POSS is synthesized by using tetraethyl orthosilicate and tetramethylammonium hydroxide and the structure of TMA-POSS is characterized by FT-IR spectra and the particle size distribution of TMA-POSS is measured by a size analyzer. Antistatic property, wetting property and dyeing performances of the modified polyester fabric are investigated. The results indicate that when the TMA-POSS concentration is larger than 4% (o.w.f.), the wetting angle reached up to 0; the peak voltage, attenuation cycle and capillary value are 1283.0 V, 16.0cm and 3.9s respectively.

The effect of atmospheric pressure dielectric barrier discharge plasma treatment on desizing polyvinyl alcohol (PVA) on polyester fabric was discussed as compared desizing with alkali through a combination of desizing rate, field scanning electron microscopy and strength test. The dyeing properties of polyester fabrics treated with atmospheric plasma have also been studied. The results show that plasma treatment can improve desizing rate, surface color depth and dye-uptake for polyester fabric.

Analysis and in-plane shear characterization of polyester plain fabric by yarn pull-out method

The aim of this study was to determine the in-plane shear properties of polyester fabric by the pull-out method and analytical relations were developed to calculate the shearing properties. After the yarn in the fabric was pulled from the top ravel region before the start of the crimp extension stage, it was found that fabric shear strength and rigidity increased when the number of pulled ends increased. In addition, when the fabric width and length increased, fabric shear strength and rigidity increased. On the other hand, the shear strength and rigidity values in untreated fabric were high compared to that of treated fabric due to the fabric treatments by softening agent. It was observed that fabric sample dimensions and the number of pull-out ends as well as the fabric treatments influenced fabric shear strength and rigidity. Also, the shear jamming angles were found to be based on the number of pulled ends. Fabric local shearing properties could be identified by pulling the yarn ends in various regions of the fabric. This could be important for the handling of the fabric during formation. The results generated from this study showed that polyester fabric shear could be measured by the yarn pull-out test.

Aging of surface properties of polyester fabrics treated with atmospheric pressure plasma for inkjet printing

Aging of plasma surface modification of inkjet printing polyester fabric was investigated. Woven polyester fabrics were exposed to atmospheric pressure air plasma and then stored at the standard condition of 20°C and 65% relative humidity to perform the aging experiments. The surface morphology and chemical compositions of the control and treated samples were analysed by scanning electron microscopy and X-ray photoelectron spectroscopy. Wetting time was used to evaluate the surface hydrophilicity on each sample. The aging effect could be detected only in the surface chemical compositions, whereas the morphology remained stable for 45 days. Research on the antibleeding property and colour strength showed that the inkjet printing property of polyester fabrics decreased with increasing aging time until a plateau value was reached. The modified fabrics should be printed within 24 h after plasma treatment in order to get fresher colour and better antibleeding performance.

Study of the Mechanical Behaviors of Fabric Made of Polyester Fibers in the Corrosive Ozone Gas Environment

Polyester textile is widely adopted in ordinary engineering applications where mechanical properties like high strength and relatively good plasticity are demanded at the same time. Though there has been some research on the change to its mechanical behavior in corrosive environments to study the effects of corrosion, for example, the ultraviolet (UV) light, the influence of corrosive media like ozone gas (O3) on its mechanical properties is rarely explored up to now. Here fabric made of polyester fibers is chosen to study the possible influence of ozone gas with extremely high concentration in the tensile strength as well as the failure behavior of this material. The aim of this research is at extending or expanding the application of polyester fabric to wider engineering areas through the study of the influence of extreme environment conditions in the mechanical properties of polyester fabric and the failure mechanism as well.

Fabrication of polyester decorative upholstery materials with low combustibility

The efficacy of the flameproofing effect of alkylphosphonic acid ammonium salt for polyester materials was investigated. It was shown that treating materials with a 12% solution of APAAS (alkylphosphonic acid ammonium salt) resulted in difficultly ignitable materials. Materials characterized by high surface density and thickness acquired higher flameproofing indexes. The study of thermolysis of polyester materials treated with APAAS showed that this flame retardant causes the formation of carbonized residue of a certain mass, composition, and structure which reduces the combustibility of the material. The flameproof properties of polyester fabrics modified with APAAS persisted over multiple chemical cleanings.

Changes induced in silk‐like polyester properties by alkoxides treatment

AbstractThe action of alkali treatment in both aqueous and alcoholic media is investigated to attain silk‐like polyester fabric. The use of alkoxide solutions is more effective on polyester fabric. Rapid loss in weight up to 15–20% occurs at ambient conditions. Immersion and padding techniques are applied. The effect of treatment on some properties of polyester fabric are given through measurements of tensile strength, drapability, permeability, density gradient, crystallinity, thermogravimetric analysis, and scanning electron microscopy. Optimization of the treatment conditions is also suggested. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 98: 1829–1837, 2005

Hydrophilic Finishes: Effect on Selected Properties of Polyester Fabric

Polyester fabric treated with four hydrophilic finishes was evaluated on the basis of soil release and resistance to soil redeposition when laundered with and without fabric softener. Test methods AATCC 130-1977 Soil Release, Oily Stain Release Method and AATCC 151-1977 Resistance to Soil Redeposition were used to evaluate effectiveness of the finishes for those properties. Soil release performance was rated high for the fabrics with hydrophilic finishes when laundered with and without fabric softener. Durability of the finished fabrics through 20 launderings was satisfactory. The finishes varied in resistance to soil redeposition. Fabric softener significantly improved soil redeposition performance of all the finished fabrics. There was a tendency for finishes to lose effectiveness in resistance to soil redeposition as launderings progressed. The unfinished fabric (control) performed poorly for both soil release and soil redeposition when laundered without fabric softener but improved considerably when fabric softener was used.
