Unveiling the TFP Nexus with ICT and IPRs: An Empirical Analysis of Textile & Apparel Industry of Pakistan

Textile and apparel industries of Pakistan are the largest industrial sector contributing about 60% to total exports and 25% of value-added of the manufacturing sector. The degree of competitiveness in this sector is closely associated with their Total Factor Productivity (TFP), which can be enhanced through trade liberalization, efficient and effective use of Information and Communication Technology (ICT), protection of intellectual property rights (IPRs) along with the investment in human capital, and advertisement expenditures. Additionally, investment in machinery and equipment and the role of subsidies cannot be ignored in enhancing TFP growth. This study utilizes data from the 2005-06 Census of Manufacturing Industries. Total factor productivity has been calculated employing the methodology of Tomiura (2007). The results indicate TFP is positively and significantly affected by ICT, IPRs, investment in machinery & equipment, human capital, import duties, subsidies for exports on TFP growth. The safeguarding textile and apparel industries from foreign competition relocates resources towards improving TFP whereas incorporation of ICT and IPRs enables firms to realize benefits of foreign developed technology which further improves TFP growth. Furthermore, the effect of advertising expenditures on TFP is positive but it lacks statistical significance.

An Investigation of Fastness and Potential Antibacterial Features on Cotton Fabric Colored with Novel Azo Compounds

Novel azo compounds were synthesized by diazotization of aniline and of 3-aminopyridine in the presence of NaNO2 and HCl, followed by coupling with 2-methylresorcinol in alkaline media. The structures were characterized using FT-IR, 1H NMR, and 13C NMR analysis. The main purpose of the present study is to investigate coloration applications, and antibacterial and fastness properties of the new azo structures in textile industry. Exhaust dyeing processes were applied on cotton fabric. Color strength ( K/ S values), L, a*, and b* values were measured. The color fastness values (to rubbing, light, perspiration, washing) of azo compounds on cotton fabric were presented according to ISO standards for comparison. Antibacterial activity assessment of the colored fabrics was performed according to AATCC 147-2016 test method against two types of bacteria: Staphylococcus aureus and Klebsiella pneumoniae. The fabric dyed with 2-methyl-4-[pyridin-3-yldiazenyl]benzene-1,3-diol demonstrated acceptable antibacterial activity against S. aureus.

Plasma Technology Applied to Improve Wettability for Emerging Mycelium-Based Materials

Plasma technology is increasing its applications in the textile industry for conferring surface functionalities through greener processes. In this study, plasma treatments are studied to improve the wettability of mycelium-based material, an emerging material with a lot of potential in the near future. The plasma effect was characterized by assessing the added functionality (wettability) and inspecting surface modifications with different techniques, such as scanning electron microscopy (SEM) and X-Ray photoelectron spectroscopy (XPS). Low pressure plasma (LPP) treatments were successfully applied into the mycelium-based material and optimal power of discharge and treatment time were set for this material (750 W, 17.5 min). With the optimized LPP treatments, the water absorption capacity of mycelium-based material was improved by 2000% and some surface morphological modifications were observed by SEM analysis. On the other hand, XPS analysis demonstrated how the plasma treatment changes the surface composition.

A green and economic approach to synthesize magnetic Lagenaria siceraria biochar (γ-Fe2O3-LSB) for methylene blue removal from aqueous solution.

In the printing and textile industries, methylene blue (a cationic azo dye) is commonly used. MB is a well-known carcinogen, and another major issue is its high content in industrial discharge. There are numerous removal methodologies that have been employed to remove it from industrial discharge; however, these current modalities have one or more limitations. In this research, a novel magnetized biochar (γ-Fe2O3-LSB) was synthesized using Lagenaria siceraria peels which were further magnetized via the co-precipitation method. The synthesized γ-Fe2O3-LSB was characterized using FTIR, X-ray diffraction, Raman, SEM-EDX, BET, and vibrating sample magnetometry (VSM) for the analysis of magnetic properties. γ-Fe2O3-LSB showed a reversible type IV isotherm, which is a primary characteristic of mesoporous materials. γ-Fe2O3-LSB had a specific surface area (SBET = 135.30 m2/g) which is greater than that of LSB (SBET = 11.54 m2/g). γ-Fe2O3-LSB exhibits a saturation magnetization value (Ms) of 3.72emu/g which shows its superparamagnetic nature. The batch adsorption process was performed to analyze the adsorptive removal of MB dye using γ-Fe2O3-LSB. The adsorption efficiency of γ-Fe2O3-LSB for MB was analyzed by varying parameters like the initial concentration of adsorbate (MB), γ-Fe2O3-LSB dose, pH effect, contact time, and temperature. Adsorption isotherm, kinetic, and thermodynamics were also studied after optimizing the protocol. The non-linear Langmuir model fitted the best to explain the adsorption isotherm mechanism and resulting adsorption capacity ( =54.55mg/g). The thermodynamics study showed the spontaneous and endothermic nature, and pseudo-second-order rate kinetics was followed during the adsorption process. Regeneration study showed that γ-Fe2O3-LSB can be used up to four cycles. In laboratory setup, the cost of γ-Fe2O3-LSB synthesis comes out to be 162.75 INR/kg which is low as compared to commercially available adsorbents. The results obtained suggest that magnetic Lagenaria siceraria biochar, which is economical and efficient, can be used as a potential biochar material for industrial applications in the treatment of wastewater.

Application of chemically modified waste tucumã (Astrocaryum aculeatum) seeds in the biosorption of methylene blue: kinetic and thermodynamic parameters.

Dye effluents cause diverse environmental problems. Methylene blue (MB) dye stands out since it is widely used in the textile industry. To reduce the pollution caused by the MB, we developed biosorbents from tucumã seeds, where the in natura seeds were treated with NaOH (BT) and H3PO4 (AT) solutions and characterized by Boehm titration, point of zero charges, FTIR, TGA, BET, and SEM. It was observed that the acid groups predominate on the surface of the three biosorbents. The process was optimized for all biosorbents at pH = 8, 7.5g/L, 240min, C0 = 250mg/L, and 45 ℃. BT was more efficient in removing MB (96.20%; QMax = 35.71mg/g), while IT and AT removed around 60% in similar conditions. The adsorption process best fits Langmuir and Redlich-Peterson isotherms, indicating a hybrid adsorption process (monolayer and multilayer) and pseudo-second-order kinetics. Thermodynamic data confirmed an endothermic and spontaneous adsorption process, mainly for BT. MB was also recovered through a desorption process with ethanol, allowing the BT recycling and reapplication of the dye. Thus, an efficient and sustainable biosorbent was developed, contributing to reducing environmental impacts.

Carbon nanomaterials, with their exceptional properties, exhibit promising potential in the textile industry. In this study, we prepare sports clothing containing graphene nanoparticles (GNPs) for college physical education (PE) teachers and investigate its performance such as moisture absorption, breathability, wear resistance, and antimicrobial properties. The results showed that the moisture absorption rate and air permeability of the sports clothing containing GNPs were significantly superior (31.3% and 203.5 mm/s respectively) compared to conventional sports clothing. Additionally, our findings demonstrated that the sports clothing containing GNPs has excellent wear-resistance and antimicrobial properties. In conclusion, these findings suggest that GNPs can enhance performance in sportswear, which not only provides university physical education instructors with high-quality and durable athletic gear but also offers novel insights into the sports equipment industry.

Highly effective ultrafiltration membranes based on plastic waste for dye removal from water.

Applicable and low-cost ultrafiltration membranes based on waste polystyrene (WPS) blend and poly vinylidene fluoride (PVDF) were effectively cast on nonwoven support using phase inversion method. Analysis was done into how the WPS ratio affected the morphology and antifouling performance of the fabricated membranes. Cross flow filtration of pure water and various types of polluted aqueous solutions as the feed was used to assess the performance of the membranes. The morphology analysis shows that the WPS/PVDF membrane layer has completely changed from a spongy structure to a finger-like structure. In addition, the modified membrane with 50% WPS demonstrated that the trade-off between selectivity and permeability is met by a significant improvement in the rejection of the membrane with a reduction in permeate flux due to the addition of PVDF. With a water permeability of 50 LMH and 44 LMH, respectively, the optimized WPS-PVDF membrane with 50% WPS could reject 81% and 74% of Congo red dye (CR) and methylene blue dye (MB), respectively. The flux recovery ratio (FRR) reached to 88.2% by increasing PVDF concentration with 50% wt. Also, this membrane has the lowest irreversible fouling (Rir) value of 11.7% and lowest reversible fouling (Rr) value of 27.9%. The percent of cleaning efficiency reach to 71%, 90%, and 85% after eight cycles of humic acid (HA), CR, and MB filtration, respectively, for the modified PS-PVDF (50%-50%). However, higher PVDF values cause the membrane's pores to become clogged, increase the irreversible fouling, and decrease the cleaning efficiency. In addition to providing promising filtration results, the modified membrane is inexpensive because it was made from waste polystyrene, and as a result, it could be scaled up to treat colored wastewater produced by textile industries. PRACTITIONER POINTS: Recycling of plastic waste as an UF membrane for water/wastewater treatment was successfully prepared and investigated. Mechanical properties showed reasonable response with adding PVDF. The modified membrane with 50% PS demonstrated that the trade-off between selectivity and permeability is met by a significant improvement in the rejection.

Fiber Characteristics of the Dromedary Camel in the Arabian Peninsula

Dromedary camel fibers have long been utilized to make clothes, tents, ropes, mats, and carpets, however, only a minority of these fibers are currently used to produce textiles. Dromedary fiber classification based on quality traits is essential to investigate its textile potential. Therefore, the objectives of this study were to (1) develop a classification protocol for dromedary camel fibers based on crimp (i.e., shape), (2) investigate the characteristics of each fiber class using length, diameter, and medulla (i.e., the innermost hair layer) and (3) determine which fiber class is most suitable for the textile industry. Fiber samples were obtained from the mid-torso of 32 Arabian Peninsula camels of different types. Five crimp categories were identified (straight, C-shaped, wavy, ringed, and kinky). Across all crimp categories, the average length ranged from 20.20 – 43.93mm whereas the mean fiber diameter ranged from 29.74 – 72.11 μm. Percent medullation extended from 68 to 100% with noticeable variation between crimp categories. Overall, fiber traits significantly differed between the crimp categories. Kinky hair was particularly distinct from the other crimp categories. The kinky crimp category is the most suitable dromedary fiber for the textile industry because its fibers are long, fine, and has the lowest percentage of medullated fibers. Hence, we recommend that selective breeding programs and genetic studies focus on the production of dromedaries with kinky hair fibers.

Enhanced biobased carbon materials made from softwood bark via a steam explosion preprocessing step for reactive orange 16 dye adsorption

The growing textile industry produces large volumes of hazardous wastewater containing dyes, which stresses the need for cheap, efficient adsorbing technologies. This study investigates a novel preprocessing method for producing activated carbons from abundantly available softwood bark. The preprocessing involved a continuous steam explosion preconditioning step, chemical activation with ZnCl2, pyrolysis at 600 and 800 °C, and washing. The activated carbons were subsequently characterized by SEM, XPS, Raman and FTIR prior to evaluation for their effectiveness in adsorbing reactive orange 16 and two synthetic dyehouse effluents. Results showed that the steam-exploded carbon, pyrolyzed at 600 °C, obtained the highest BET specific surface area (1308 m2/g), the best Langmuir maximum adsorption of reactive orange 16 (218 mg g−1) and synthetic dyehouse effluents (>70 % removal) of the tested carbons. Finally, steam explosion preconditioning could open up new and potentially more sustainable process routes for producing functionalized active carbons.

Co-localization and analysis of miR477b with fiber length quantitative trait loci in cotton.

Cotton is an important cash crop for the textile industry. However, the understanding of natural genetic variation of fiber elongation in relation to miRNA is lacking. A miRNA gene (miR477b) was found to co-localize with a previously mapped fiber length (FL) quantitative trait locus (QTL). The miR477b was differentially expressed during fiber elongation between two backcross inbred lines (BILs) differing in FL and its precursor sequences. Bioinformatics and qRT-PCR analysis were further used to analyse the miRNA genes, which could produce mature miR477b. Cotton plants with virus-induced gene silencing (VIGS) constructs to over-express the allele of miR477b from the BIL with longer fibers had significantly longer fibers as compared with negative control plants, while the VIGS plants with suppressed miRNA expression had significantly shorter fibers. The expression level of the target gene (DELLA) and related genes (RDL1 and EXPA1 for DELLA through HOX3 protein) in the two BILs and/or the VIGS plants were generally congruent, as expected. This report represents one of the first comprehensive studies to integrate QTL linkage mapping and physical mapping of small RNAs with both small and mRNA transcriptome analysis, followed by VIGS, to identify candidate small RNA genes affecting the natural variation of fiber elongation in cotton.

A Study on Natural Dye Application on Cotton Fabric using Clitoria Ternatea

In this fast fashion era dyeing is considered as a major cause for the textile pollution. It is also a cause for many deadly diseases due to the poor usage of synthetic dyes and most of the textile industry does not care about the workers and their protective wears and the workers suffer from health hazardous due the emitted effluents that gets emitted from the dyeing process. During the dyeing the synthetic dyes produce strong fumes, and these are highly carcinogenic and while disposing the dye there are proper treatment for the disposal otherwise this will create a huge damage to the environment. The present study focuses on colour ant that is extracted from clitoriaternatea flower on cotton fabric has been studied using alum. The wash, rub, light, and perspiration fastness of the dyed samples have been tested. It is discovered that clitoriaternatea dye can be successfully used for the dyeing of cotton to obtain a wide range of colours by using various mordant. In regard to colour fastness test samples exhibit excellent fastness to sunlight, washing, crocking, perspiration, and saliva.

Butea monosperma aided green synthesis of α-MoO3 nanoparticles: Biosensing and photocatalytic activity towards hazardous dyes and rangoli colorants

Increasing environmental pollutants and the need for efficient photocatalytic and biosensing materials have led to the development of novel green synthesis methods. In this study, MoO3 nanoparticles (NPs) were successfully synthesized by using green chemistry approach. In that respect, Butea monosperma leaf powder was used as a novel fuel. Structural parameters, optical properties, shape and morphology of MoO3 NPs are examined using XRD, FTIR, UV–Vis spectrophotometer, Photoluminescence (PL), SEM - EDAX and TEM analysis. The use of MoO3 NPs as a dusting agent in fingerprint applications results in improved fingerprint visibility, which is useful in forensic investigation. In this study, we modified the GCE electrode surface with MoO3 NPs to develop a highly sensitive dopamine (DA) sensor. Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and differential pulse voltammetry (DPV) were used to investigate the electrochemical behaviour and electrocatalytic property of the MoO3 NPs. The synthesized NPs have excellent performance for detection of highly sensitive biologically active DA. The sensor exhibits a low detection limit of 0.45 μM. Additionally, it shows good stability, simplicity, and selectivity for the rapid detection of DA. MoO3 NPs shows good photocatalytic activity under UV light for the degradation of important textile industries dye such as methylene blue (MB) and harmful rangoli colors which are available in local shops of Tumkur, Karnataka. The photocatalyst exhibits a remarkable 97 % degradation efficiency for MB dye. Coumarin studies ensure the effective generation of OH radicals on the surface of the photocatalyst, leading to the degradation of organic dyes. Additionally, the MoO3 NPs reusability was examined, and even after four cycles, the level of photocatalytic activity did not drop much. Therefore, it is a potential photocatalyst for the processing of organic colours.
