The crease resistance of cotton fabrics is not satisfactory to meet the contemporary requirements for "easy-care" textile materials. The conventional durable press finishes which improve the crease-resistance of cotton fabrics are mostly achieved on the basis of a condensation reaction at high temperature between formaldehyde based N-methylol compounds, such as Di-Methylol Dihydroxy Ethylene Urea (DMDHEU) or its derivatives and cotton. However, the formaldehyde, which is released during the fixation procedure, has been identified as a potential human carcinogen. In the last 2 decades many efforts have been made to develop formaldehyde-free cross-linking agents. The most promising formaldehyde-free reagents, nevertheless are the polycarboxylic acids are 1,2,3,4 BTCA and polymers of maleic acid. Predominantly 1,2,3,4 BTCA is higher cost than polymaleic acid, so commercial application is an intricate. The reaction with the cellulose substrate proceeds ester cross-linking, catalyzed by sodium hypophosphite. This work deals with the application of polymaleic acid, and its impact on various properties of cotton such as crease resistance angle (CRA), tensile strength, tearing strength and abrasion resistance were investigated. Finally PMA treated fabric was compare with DMDHEU treated fabrics.

Nowadays the fabrics produced from cotton fibers have the largest share in the textile market. However, their creaseresistance is not satisfactory to meet the contemporary requirements for "easycare" textile materials. The conventional durable press finishes improving the crease-resistance of cotton fabrics are mostly achieved on the basis of a condensation reaction at high temperature between formaldehyde based N-methylol compounds, such as Di-Methylol Dihydroxy Ethylene Urea (DMDHEU) or its derivatives and cotton. However, the formaldehyde, which is released during the fixation procedure, has been identified as a potential human carcinogen.

Predominantly 1,2,3,4 BTCA is high cost than Polymaleic acid, so commercial application is an intricate. The reaction with the cellulose substrate proceeds ester crosslinking, catalyzed by sodium hypophosphite. This present work dealt with the application of Polymaleic Acid and its impact on various properties of cotton such as Crease resistance angle (CRA), tensile strength, tearing strength and abrasion resistance were investigated. Finally PMA treacted fabric was compare with DMDHEU Treated fabrics.

In the textile wet processing industry, different chemicals are used for the different finishing purposes which affects the environment. Thus, this article will concentrate on different ways of bio-finishing fabrics in order to do comparatively less harm to the environment, while in textile industries, environmental protection methods are being given a growing importance.

Moisture flow through the apparel fabric is important in the textile applications from the comfort point of view. Comfort can be defined by many ways according to the wearer, so many researchers attempt to defined comfort as temperature regulation of the body, the absence of unpleasant or discomfort, influenced by the physiological reaction of the wearer. For this study three weaves i.e. plain, twill and satin with constant warp i.e. modified polyester and ends per inch of 112 is taken and weft of three types in each weave, i.e. modified polyester, normal polyester and cotton and three pick density in each weave. The result shows wicking behaviour of modified polyester is higher than normal polyester. Water absorbency of modified polyester is higher than normal polyester. There is no significant difference in the fabric by varying the pick density. The study shows that the modified polyester has higher comfort than normal polyester fabrics.
