繊維用酵素

繊維加工用酵素は、工場の処理温度と中性付近のpHで特定の湿式加工 — starch糊の分解、セルロース繊維の平滑化、残留漂白剤の分解 — を行う生体触媒です。 繊維工場で主に使われるのは3種で、amylase、cellulase、catalaseです。それぞれが1つの基質にのみ作用し布の他の部分には手を付けないため、より過酷な化学的・機械的手法に置き換わりました。

Amylase hydrolyzes starch size so it rinses off cleanly before dyeing, and catalase decomposes the hydrogen peroxide left after bleaching so it cannot interfere with reactive dyes. Both run in narrow windows; an amylase optimized near 60-70°C and pH 6 loses activity outside that band. Specify the enzyme grade to your bath temperature and pH rather than dosing more product to compensate for a poor match.

Cellulase drives biopolishing and denim bio-stoning. It shaves the protruding fibrils that cause pilling, smooths the surface, and replaces pumice stones in garment laundries. Here is the real trade-off: the same activity that smooths the surface also removes fabric, so an over-dose costs you tensile strength and weight along with the fuzz. Control dose, time, and temperature, and deactivate the enzyme on schedule.
