Fabric Comfort

The smart control of cotton fabric comfort by cross-linking thermo-responsive random copolymer is investigated. The monomers 2-(2-methoxyethoxy) ethoxyethyl methacrylate (MEO2MA) and ethylene glycol methacrylate (EGMA) with a molar ratio of 17:3 are selected to synthesize the thermo-responsive random copolymer poly(2-(2-methoxyethoxy) ethoxyethyl methacrylate- co-ethylene glycol methacrylate), abbreviated as P(MEO2MA- co-EGMA). By using citric acid as a cross-linking agent, the obtained P(MEO2MA- co-EGMA) is successfully immobilized onto cotton fabrics. Smart control is achieved from the thermo-responsive behavior of the copolymer. Cross-linked P(MEO2MA- co-EGMA) will collapse when the ambient temperature exceeds its transition temperature. Therefore, the formerly compact P(MEO2MA- co-EGMA) layer will switch to a porous structure, and the air/moisture permeability of the textiles is enhanced. As the comfort of the textiles is closely related to the air/moisture permeability, a smart control of the cotton fabric comfort can be realized. In addition, the softness of cotton fabrics with and without thermo-responsive polymers does not show a prominent change, even when the applied solution concentration is as high as 16% (wt%). On the contrary, the stiffness of the cotton fabric coated with poly( N-isopropylacrylamide) (PNIPAM) is significantly higher than the original cotton fabric, indicating that homo PNIPAM is less suitable for textiles used in daily lives. Moreover, the whiteness and mechanical properties are studied and stay unchanged after cross-linking. As a consequence, the introduction of P(MEO2MA- co-EGMA) into textiles can provide textiles with smart control of cotton comfort, and it will not influence the wearabilities of the textiles.

In printing and resin finishing of cotton fabrics, the curing step is involved twice, firstly for fixation of reactive dye and secondly for the fixation of resin for proper cross-linking. In developing country like Pakistan, where cotton is a major portion of textile exports, the elimination of one fixation stage is economical and advantageous. This study dealt with the simultaneous fixation of wrinkle-free finish (resin) and reactive dye printing for cost effectiveness. The processed route of treatment imparted a maximum dry crease recovery angle of 230° and color strength up to 89.89%. The produced fabrics were characterized using crocking fastness (dry and wet), color strength sum %, color fastness to laundry, crease recovery angle, and wrinkle recovery by appearance method. Response surface optimizer gave good composite desirability value (0.08300) with color strength % of up to 73.73 and dry crease recovery angle up to 218°.

Most of the cotton fabrics at present are dyeing using reactive dyes which requires large quantities of salt, further produce large amount of effluent load to the environment in the form of more salinity in the effluent water along with other pollutants. In order to reduce the salinity in the waste water lot of investigations were carried out. Cotton fabrics pretreated with chitosan were dyed with reactive dyes. Pretreated samples were dyed without using salt as an electrpolyte. The influence of pretreatment on kinetics in dye bath i.e rate of dye particle movement towards the fabric, wash fastness, rubbing fastness was determined. The results of this study shows that the pretreatment of cotton with chitosan increases dye uptake and shows good fastness to washing and rubbing same as that of conventional way of dyed samples. It was determined that chitosan was effective cross linking agent in salt-free dyeing of cotton fabrics.

Purpose Among various metal oxide nano particles, MgO NPs and ZnO nanoparticles (NPs) in particular are gaining increasing attention due to their multifunctional characteristics, low cost and compatibility with textile materials. Each type of nanoparticle excels over others in certain properties. As such, it is often crucial to carry out comparative studies of NPs to identify the one showing higher efficiency/output for particular applications of textile products. Design/methodology/approach In the investigation reported in this paper, ZnO NPs and MgO NPs were synthesised via sol-gel technique and characterised. For comparative analysis, the synthesised NPs were evaluated for multiple properties using standard procedures before and after being applied on cotton fabrics by a dip-pad-dry-cure method. Findings XRD and FTIR analyses confirmed the successful synthesis of ZnO and MgO NPs. Homogeneous formation of desired NPs and their dense and uniform deposition on the cotton fibre surface were observed using SEM. ZnO NPs and MgO NPs coatings on cotton were observed to significantly enhance self-cleaning/stain removal properties achieving Grade 5 and Grade 4 categories, respectively. In terms of ultraviolet (UV) protection, ZnO or MgO NP coated fabrics showed UPF values of greater than 50, i.e. excellent in blocking UV rays. MgO NPs exhibited 20% cleaning efficiency in treating reactive dye wastewater against ZnO NPs which were 4% efficient in the same treatment, so MgO was more suitable for such type of treatments at low cost. Both NPs were able to impart multifunctionality to cotton fabrics as per requirement of the end products. However, ZnO NPs were better for stain removal from the fabrics while MgO NPs were appropriate for UV blocking. Originality/value It was therefore clear that multifunctional textile products could be developed by employing a single type of cost effective and efficient nano particles.

In this study, cellulase pre-treated mercerized cotton (EMC) fabrics were treated with citric acid (CA), butane tetra carboxylic acid (BTCA) and nano TiO2 (NTO) to produce fabric with enhanced cross-linking, self-cleaning, and antibacterial properties. However treatment of EMC fabrics with NTO/CA/BTCA has not been reported. The NTO particles were stabilized on the cotton surface using CA/BTCA cross-linking agents. In order to create optimum dry crease recovery angle (DCRA), self-cleaning based on (ΔE*) and bacteria reduction against Gram-positive and Gram-negative bacteria, the appropriate models were obtained based on Design of Expert software. The roles of CA, BTCA and NTO concentrations in cross-linking, self-cleaning, and antibacterial properties of the EMC fabric were investigated using response surface methodology (RSM). Overall, the cellulase pre-treatment of the mercerized cotton fabrics improved the antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria, and also enhanced DCRA and self-cleaning properties significantly as compared with control samples. Also, reflectance spectra analyses (200–400 nm) and Scanning Electron Microscopy (SEM) were employed to confirm the NTO particles on the EMC fabric surface.
