Abstract

In this paper, the nonformaldehyde agent 1,2,3,4-butanetetracarboxylic acid was used for durable press finishing of silk fabric. To optimize the finishing, the effects of the amount of sodium hypophosphite, 1,2,3,4-butanetetracarboxylic acid and citric acid, curing temperature and curing time were examined. It was found that the wet wrinkle recovery angle had an obvious improvement from 179° to 273°, and that the finishing had a very small effect to the breaking strength.

Abstract

Significant enhancement in the performance of durable press cotton fabric could be achieved through the utilization of non- formaldehyde crosslinking agents along with ionic crosslinking. Ionic crosslinking was first effected by subjecting cotton fabric succesively to partial carboxymethylation using monochloroacetic acid and sodium hydroxide, then by cationization using 3-chloro-2-hydroxypropyl trimethyl ammonium chloride known commercially as Quat-188. While the partial carboxymethylation reaction introduces the negatively charged group in the cellulose chains of cotton, the cationization reaction introduces the positively charged groups, thereby causing ionic crosslinking. The ionically crosslinked cotton was then crosslinked using either glyoxal, epichlorohydrin, or gluteral-dehyde. Most of the results obtained indicated that a balance between wet and dry wrinkle recovery angles that acquired a value as high as 300° could be obtained without loss in tensile strength and elongation at break. The results also revealed that the degree of ionic crosslinking relies on the nitrogen and carboxyl contents of the finished fabric as well as on the nature of the non-formaldehyde finishing agent used. Indeed the results of this work present a new approach to the durable press finishing of cotton, and mill trials should be conducted.

Abstract

Examines the fifthteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

Glutaraldehyde is chosen as a novel non-formaldehyde durable press finish for cotton fabrics in this investigation. The optimum technique conditions and influences of glutaraldehyde concentration and catalysts, pH value, and curing conditions for the properties of the finished fabric have been investigated in detail. The finished fabric achieves the best performance with a pH value in the range of 4 to 4.5 for the glutaraldehyde finishing bath, magnesium chloride as the catalyst, and curing conditions of 160oC for 3 minutes. In addition, in contrast to low formaldehyde resin and non-formaldehyde finishers sold in the market, the wrinkle recovery angle of the fabric finished with glutaraldehyde is better than that finished with FREEREZ NFR (DHDMI), but not as satisfactory as that finished with FREEREZ 880 (low formaldehyde 2D). However, its strength is greater than the fabric finished with FREEREZ 880, but less so than that finished with FREEREZ NFR.

Naturally colored cotton (NCC) based wovens are finished with 1,2,3,4-butanetetracarboxylic acid (BTCA), which is an environmentally friendly durable press (DP) finish

Abstract

Naturally colored cotton (NCC) based wovens are finished with 1,2,3,4-butanetetracarboxylic acid (BTCA), which is an environmentally friendly durable press (DP) finish. The colors of the NCC wovens before and after DP finishing are examined. The color fastnesses to home laundering and light irradiation are compared and evaluated. The DP finishing of BTCA has a negative effect on the color of NCC based fabrics. About 1/3 of the shade depth of the NCCs are decreased after a BTCA finishing. For both the fabrics with and without a DP finishing, home laundering results in evident color changes with decrease of shade depth. However, for probable crosslinking to pigments, a DP finishing could significantly improve the home laundering color fastness of NCCs. The performance of the color fastness to light after a BTCA finishing depends on the cotton breed. The BTCA finishing of the green NCC minimally improves the light fastness, while for the brown NCC, the color fastness to light decreases after the BTCA finishing.

Abstract

Purpose

The purpose of this study was to overcome discomfort associated with it, a resin finish was applied in conjunction with hydrophilic polyurethane.

Design/methodology/approach

The process variables included concentrations of polyurethane and resin finishes, and pH under central composite design (CCD). The fabric specimens were assessed for crease recovery angle (CRA), tensile strength and moisture management properties.

Findings

Some models were developed for prediction of CRA and overall moisture management capability (OMMC) of treated fabric. It was observed that polyurethane concentration showed a parabolic relationship with CRA and a direct relationship with OMMC, whereas resin concentration showed a parabolic relationship with CRA and an inverse relationship with OMMC. Increase in pH from acidic to alkaline resulted in a decrease in CRA but an increase in OMMC. The untreated specimen had the highest tensile strength, whereas the specimen treated with polyurethane showed the least tensile strength loss, and the one treated with resin showed the highest loss in tensile strength.

Practical implications

As the polyurethane-based finish is soft and hydrophilic, so it was expected that it would overcome the uncomfortable feature of durable press finish, and with its flexibility, the strength losses might reduce.

Originality/value

This is the first report about the investigation of effects of increasing flexibility of the cross-link by incorporating polyurethane compounds into a typical dimethylol dihydroxy ethylene urea durable press resin formulation.

Abstract

Purpose

This study aims to explore the incorporation of starch nanoparticles (SNPs) in cross-linking formulation of cotton fabrics to see their impact on fabric performance like tensile strength, dry wrinkle recovery angles, elongation at break, degree of whiteness and increase in weight as well as durability.

Design/methodology/approach

SNPs of size around 80-100 nm were successfully prepared from native maize starch by Nano precipitation technique and confirmed instrumentally by scanning electron microscope (SEM), transmittance electron microscope (TEM), Fourier transformer infrared (FTIR) spectroscopy and particle size analyzer. The latter were incorporated in cross-linking formulation of cotton fabrics encompassing different concentrations of citric acid and sodium hypophosphite at different curing time and temperature in 100 ml distilled water to a wet pickup of ca. 85 per cent. The fabric samples were dried for 3 min at 85°C and cured at specified temperatures for a specified time intervals in thermo fixing oven according to pad-dry-cure method.

Findings

FTIR spectra and SEM micrograph signified the chemical structure and surface morphology of cotton fabric before and after finishing in absence and presence of SNPs. Cotton fabric samples finished in presence of SNPs showed a higher tensile strength, elongation at break, comparable dry wrinkle recovery angles and degree of whiteness than that finished in their absence. On the other hand, the enhancement in the aforementioned performance reflects the positive impact of incorporation of SNPs in textile finishing especially with strength properties; which are one of the important requirements for industrial fabrics that can be used widely in heavy-duty applications.

Research limitations/implications

SNPs with its booming effect with respect to biodegradability, reactivity and higher surface area can be used as a novel reinforcement permanent finish for cotton fabrics instead of more hazardous materials likes poly acrylate and monomeric compounds.

Practical implications

As SNPs biopolymers is one of the important reinforcement agents, so it was expected that it would minimize the great loss in strength properties during easy-care cotton finishing and improve the fabric performance.

Originality/value

The novelty addressed here is undertaken with a view to remediate some of the serious defects of easy-care cotton fabrics using poly carboxylic acids; especially with the great loss in strength properties by virtue of using SNPs as a permanent finish. Besides, to the authors’ knowledge, there is no published work so far concerning the use of SNPs as an innovative base for production of easy-care finished cotton textiles with high performance.

Abstract

A systematical review of catalyst was provided in the paper involving the definition, the sort, effect mechanism and the influence factors which followed that the application of catalyst in the textile industry in terms of dyeing, finishing and effluents treatment. Catalyst is defined as a substance that could change the rate of chemical reaction, while it is not consumed in the overall reaction. The changing of the reaction rate by means of catalyst is known as catalysis. Catalyst could assist in either acceleration or deceleration of the reaction rate. In textile processing, especially in textile wet processing such as dyeing and finishing, for example, easy care and durable press finishes, antimicrobial finishes, ultraviolet protection finishes, flame retardant finishes and water repellent finishes, various types of catalysts will be involved for achieving desired effect. However, there is a less discussion and review on the relationship on the effect of catalyst on the final properties of the textile materials. Therefore, the aim of this paper is to provide a comprehensive review of the application of catalyst on the textile wet processing and nano-catalyst was also evaluated in the extending to the opportunities and development of textile industry.

Abstract

Purpose

This study aims to explore the incorporation of the authors previously prepared chitosan nanoparticles (CNPs) of size around 60-100 nm in the cross-linking formulation of viscose fabrics to see CNPs impact in terms of imparting multi-functional characteristics such as tensile strength, dry wrinkle recovery angles and antibacterial properties.

Design/methodology/approach

CNPs of size around 60-100 nm were incorporated in cross-linking formulations for viscose fabrics, including different concentrations of glutaraldehyde as a non-formaldehyde cross-linking agent and magnesium chloride hexahydrate as a catalyst. The formulations were applied at different curing times and temperatures in 100 mL distilled water, giving rise to a wet pickup of ca. 85 per cent. The fabrics were dried for 3 min at 85°C and cured at specified temperatures for fixed time intervals in thermo fixing oven according to the traditional pad-dry-cure method.

Findings

The above eco-friendly method for finished viscose fabrics was found to obtain high dry wrinkle recovery angle and maintain the tensile strength of the finished fabric within the acceptable range, as well as antibacterial properties against Escherichia coli and Staphylococcus aureus as a gram-negative and gram-positive bacteria, respectively. Both, scanning electron microscope and nitrogen percent on the finished fabric confirm the penetration of CNPs inside the fabric structure. Finally, viscose fabrics pageant antibacterial activity against gram-positive and gram-negative bacteria assessed even after 20 washing cycle.

Research limitations/implications

CNPs with its flourishing effect with respect to cationic nature, biodegradability, reactivity, higher surface area and antimicrobial activity; in addition to glutaraldehyde as non-formaldehyde finishing agent can be used as multi-functional agents for viscose fabrics instead of DMDHEU, polyacrylate and monomeric composites as hazardous materials.

Practical implications

CNPs as cationic biopolymers were expected to impart multi-functional properties to viscose fabrics especially with obtaining reasonable dry wrinkle recovery angle and tensile strength in addition to antibacterial properties.

Originality/value

The novelty addressed here is undertaken with a view to impart easy care characteristics and antibacterial activities onto viscose fabrics using CNPs as antimicrobial agent and glutaraldehyde as non-formaldehyde durable press finishes to-replace the traditional formaldehyde-based resins. Besides, to the authors’ knowledge, there is no published work so far using the above cross-linking formulation written above.
