Abstract

80℃에서 40분간 비교적 저온으로 100%면을 저온표백하는 방법에 관한 것이다.It relates to a low temperature bleaching of 100% cotton at a relatively low temperature for 40 minutes at 80 ℃.

저온에서 표백함으로서 에너지가 절약되고 아염산 가스발생이 감소되고 이에 의한 표백기계의 부식이 감소된다.Bleaching at low temperatures saves energy and reduces the generation of chlorite gas, thereby reducing corrosion of the bleaching machine.
