Abstract
Embodiments of the invention provide a method for manufacturing woven or knit fabrics with improved shrink and crease resistance and good shape memory after repeated washing. The method comprises (a) contacting an enzyme treatment composition with a cellulosic material (e.g., cotton fabric), the enzyme composition comprising an enzyme; and (b) treating the cellulosic material with a polymeric resin composition. Embodiments of the invention also provide a fabric manufactured by sequentially treating the fabric with an enzyme composition and a resin treatment agent.
Claims16
A cotton fabric manufactured by sequentially treating said fabric with an enzyme composition and a resin treatment agent comprising modified di-hydroxyl-methyl-di-hydroxyl ethylene urea (DMDHEU), wherein said enzyme composition comprises a pectinesterase, wherein, even after 20 instances of normal home laundering, the fabric displays a pilling grade of greater than 3.0 according to ASTM D3512 and a colorfastness grade of greater than 3.0 according to AATCC Evaluation Procedure 1 Gray Scale for Color Change.
A cotton fabric manufactured by sequentially treating said fabric with an enzyme composition and a resin treatment agent including a resin selected from the group of modified N-methyl-di-hydroxyl-ethyl urea and polyhydric carboxylic acid, wherein said enzyme composition comprises a pectinesterase, wherein, even after 20 instances of normal home laundering, the fabric displays a pilling grade of greater than 3.0 according to ASTM D3512 and a colorfastness grade of greater than 3.0 according to AATCC Evaluation Procedure 1 Gray Scale for Color Change.
