Abstract

The invention provides a cashmere blanching method which is characterized by comprising the following steps: soaking cashmere in clear water with the bath ratio of 1:50, and then adding 2-5g / L alkyl sodium sulfonate and 0.1-2g / L detergent LS to obtain treating fluid; adjusting the pH value of the treating fluid to be 7-7.5, then heating to 55-65 DEG C at the heating rate of 1-2 DEG C / min, and keeping for 10min; then cooling and washing with water three times, namely washing with warm water at 45 DEG C once and washing with cold water twice, wherein the bath ratio is respectively 1:45; and then wiping.

Description

[0001] This application is a divisional application of an invention patent application with the application number 2014103046276, the title of the invention is "a cashmere low-temperature bleaching agent and its bleaching method", and the application date is June 30, 2014. technical field [0002] The invention relates to the technical field of fiber bleaching, in particular to a cashmere low-temperature bleaching agent and a bleaching method. Background technique [0003] Cashmere is a precious textile raw material. Natural cashmere comes in various colors such as white, blue, purple, and brown, among which the most precious is white, so cashmere needs to be bleached. However, the cost of the bleaching agent and bleaching process in the prior art is high, the damage to the fiber is relatively large, and the cashmere fiber after bleaching is easy to yellow. Therefore, seeking the bleaching agent and bleaching method under low temperature to reduce the damage to fiber has jus...
