The tensile strength of durable press finished cotton fabrics is significantly reduced as a result of the crosslinking process. In this research, we investigated the effects of acid degradation and crosslinking of cellulose on the mechanical strength of the cotton fabric crosslinked with polycarboxylic acids, and evaluated various factors influencing the mechanical strength of durable press fin...

Nano-ZnO was prepared by direct precipitation method with zinc chloride and sodium carbonate anhydrous as raw materials, and its particle size and dispersion were characterized by TEM. The effects of concentration and the ratio of reactants and reaction temperature on its dispersion in aqueous solution were analyzed and the best reaction conditions were as follows: reaction temperature 60 , ult...

Bleaching of organic cotton fabric can be done with hydrogen peroxide in which Catalase, a non-toxic, environmentally friendly biocatalyst is used to remove the residual H2O2 in a cost effective way for the better improvement of the cellulosic fabric properties. Enzyme treated organic cotton fabric was dyed with a natural dye obtained from orange corolla tube of Nyctanthes arbor-tristis flower ...

Three sulfatoethylsulfone reactive dyes have been synthesized and were applied to mill desized, bleached and mercerized cotton fabric. Effect of different dyeing parameters i.e. salt concentration, dyeing time, dyeing temperature and pH of dye solution were being optimized by exhaust dyeing method. The fixation (%F) of the synthesized dye molecules with the cotton fabrics was also studied. Cott...

OBJECTIVE Avoiding potentially irritating contact is a key point in vulvar lichen simplex chronicus (VLSC) management. This study aims to assess the use of nonirritating silk fabric underwear (Dermasilk) as an adjuvant tool in the treatment of VLSC. METHODS Twenty women with VLSC were enrolled in a 1-week open-label active treatment phase with topical 0.1% mometasone furoate (MMF) ointment. P...

Cutinase from Thermobifida fusca was used to esterify the hydroxyl groups of cellulose with the fatty acids from triolein. Cutinase and triolein were pre-adsorbed on cotton and the reaction proceeded in a dry state during 48 h at 35°C. The cutinase-catalyzed esterification of the surface of cotton fabric resulted in the linkage of the oleate groups to the glycoside units of cotton cellulose. Th...

Lysozyme was attached to three cotton fabrics through a glycine amino acid linker esterifi ed to cotton cellulose. Lysozyme bound to cotton twill using a carbodiimide-mediated coupling reaction gave the best lysozyme incorporation (16.1 mg/g of cotton). Cotton spunlace nonwoven fabric bound slightly less lysozyme (12.8 mg/g of cotton), but had the best antimicrobial activity. Woven print cloth ...

This research deals with the synthesis of nanosized copper as colloidal solution and its application to cotton fabric. Copper nano colloids were prepared by chemical reduction of copper salt using sodium borohydride as reducing agent in presence of trisodium citrate. The size and size distribution of the particles were examined by particle size analyzer and the morphology of the synthesized par...

Jute is a strong, stiff, natural fiber. When blended with cotton it makes a sturdy but prickly fabric due to protruding surface jute fibers. Samples of jute-cotton blended fabric were treated with commercial cellulases, xylanases and pectinases individually and in combination at various concentrations in order to smooth and soften the fabric. Enzyme treatment was carried out at 50°C in the pres...

Few can dispute the tremendous values of linen, which is one of nature’s greatest treasures. Linen is a longer-staple category, and as such the fibre is spun on a long-fibre spinning system. Due to the coarseness and stiffness of the fibre, linen fabrics are subjected to a strong bleaching action to reduce the stiffness of the fabric. Linen is also blended with other compatible natural and manm...
