Abstract

The invention discloses an arghan biochemistry degumming technique, which comprises working procedures of pre-pickling, washing, biochemistry degumming treatment, denaturation treatment, acid cleaning, beating fiber, rinsing, acid cleaning, oil feed and drying; wherein, the biochemistry degumming treatment is that the fibril is put into treatment fluid with 2.5-3.5g / L concentration of enzyme preparation; the bath ratio is 1:1.5-17; the temperature ranges from 40-50 DEG C; the processing time is 12H. The biological enzyme preparation is used for degumming in the process, which not only reduces the dosage of chemical agent and environment pollution but also reduces the damage of the degumming process on the fiber, and increases the quality of the fiber. The processed steps are all carried out in normal atmosphere and the treatment temperature is low, thus reducing energy consumption. Fiber products are pure white, soft and the fineness can reach 500 counts. The fiber can be spin in a mixing or a blending way, which totally meets the spinning requirements.

Description

technical field [0001] The invention relates to a fibril degumming process in the application field of textile technology, in particular to a pineapple leaf fiber biochemical degumming process. Background technique [0002] Pineapple leaf fiber is a new kind of textile raw material, which must be degummed as a textile raw material to remove the colloid glued with the pineapple leaf fiber bundle. At present, the degumming method of pineapple leaf fiber is mainly chemical degumming, that is, soaking the fibrils with acid first, then putting the fibrils into a solution of liquid alkali, trisodium phosphate, and water glass for pressure scouring, and then sequentially soaking Acid, alkali dipping, and then remove lignin, oil, dehydration and drying steps to obtain fiber products. Although the chemical degumming method is simple, it uses a large amount of strong acid and strong alkali, causing serious chemical pollution and great damage to the fiber, and the treatment process re...
