Abstract
Bleaching system applying horseradish peroxidase (HRP) was lately attracted industrial attention for its economizing energy and its significancy to protect the dye transfer. Since fabric mechanical properties should change during processing chemical treatment, it is worth to examine how the physical property changed. And this topic might be most important from the view point of fabric end-use. The fabric physical quality was evaluated objectively on the unfinished/finished cotton fabrics by using mechanical properties such as tensile, bending, shear, compressional and surface properties from the measurement. Unfinished sample and samples finished with two kinds of bleached system were prepared: one with a mixture of horseradish peroxidase (HRP) and hydrogen peroxide (H2O2) and the other with percarbonate. Fabric mechanical properties and hand values derived from physical values were compared among samples and discussed the effect of each systems on the fabric quality. A mixture of horseradish peroxidase (HRP) and hydrogen peroxide (H2O2) system reduced the fabrics hairiness and protected the disordering of intra -yarn. These structural change would reflect the high performance of handle values, which was higher than that of the other samples.
