“…The influences of fiber length on toughness appear to diminish as strength is decreased or rigidity of fiber structure is increased by crosslinking treatment. The relationships of fiber-bundle toughness to yarn toughness for three cottons differing in chemical and mechanical treatments have been reported [5]. The pattern of relationship for Pima cotton with long fibers followed that established by the Bobshaw and Deltapine 15 cottons having fibers of comparable lengths.…”

Fiber toughness, fabric construction, and pretreatment were found to affect abrasive wear in permanent-press trouser cuffs. Samples of Pima S-2, Hopi Acala, and Deltapine 15 cottons were processed into twelve constructions of print-cloth weight fabrics. Cross-linking with the dimethylol dihydroxyethyleneurea-type resin was applied as a continuous process to fabrics after scouring and after slack mercerizing. Nitrogen contents of treated fabrics show that type of cotton, fabric construction, and pretreatment affected the amounts of resin reacted with the fabric. Pima cotton had the lowest and Deltapine the highest level of nitrogen in almost every fabric construction. Pima cotton fabrics showed less wear during conventional abrasion test and laundering and greater crease-recovery angles than did the other cottons. Cuffs of basket-weave fabrics with 0.87% nitrogen showed less crease wear during laundering than did plain weave at 0.64% nitrogen. At comparable nitrogen content, slack-mercerized fabrics were more durable at a higher crease-recovery angle than were cuffs made from scoured fabrics. ~

“…[8] and Rebenfeld [103, among others, found that tension during the resin treatment reduced the strength loss caused by the resin treatment. Others [1, 3,5,9,11,13] have . found that swelling and stretching before resin treatments can improve the strength of fibers and yarns and improve the strength retention after resination.…”

Six cotton samples were slack-mercerized and stretched to 0.94, 1.0, and 1.036 of the original length. All treatments were given an overtreatment of durable-press resin. The effect on 3.2-mm-gauge bundle tenacity and elongation depended on the amount of stretching. Samples slack-mercerized and stretched to original length increased in tenacity an average of 50%, and with an overtreatment of resin, 89% of the tenacity was retained. Samples differed in their reactions to the treatments. The percent retention of tenacity after treatment varied inversely with the ratio of the 3.2-mm-gauge length tenacity to the zero-gauge length tenacity of the untreated fibers. Clamps and stretchers developed to stretch the mercerized cotton fiber bundles are described. ' . '

SYNOPSISEasy-care finishing of cotton fabrics invariably results in the loss of mechanical properties of the fabrics. There have been many attempts from time to time by different workers to reduce the above loss in the mechanical properties. But the problem is yet to be resolved satisfactorily. As the uniform distribution of cross-links in the resin-finished structure of cellulose is the key for achieving a better balance of mechanical properties, the present work aims a t a suitable modification of the cellulose matrix to achieve the goal. The paper reports the mechanical properties of the modified and cross-linked cotton yarn. The crosslinked samples of the modification treatment involving swelling the yarn a t normal stretch with 20% NaOH and partially acetylating without washing off the alkali have displayed higher tenacity, elongation, and toughness, with better easy-care properties as compared to the control.
