Abstract

The invention discloses a degumming method of Apocynum venetum bast. The degumming method of the Apocynum venetum bast comprises the following steps: ammonia water and tap water are mixed in a volume ratio of 1:1000 to obtain a soaking solution, Pectobacterium chrysanthemi variant strain LM bacterial suspension is added according to the inoculation quantity of 2% into the soaking solution for even mixing, and the mixture is added into the Apocynum venetum bast according to the bath ratio of 1:18-1:22 for fermentation for 15h-20h in a thermostatic oscillator at 33-37 DEG C at the rotation speed of 160r / min-200r / min to obtain a pretreated material; the Apocynum venetum bast in the pretreated material is taken out and beaten, and colloid attached to the surface of Apocynum venetum fiber can be washed with clear water to obtain the Apocynum venetum fiber. The method can effectively remove hemicellulose, pectin and lignin and other colloids in Apocynum venetum, the Apocynum venetum fiber is dispersed and soft; degumming weight loss rate reaches 30%, and the method has the advantages of less Apocynum venetum fiber damage, low energy consumption, and high chemical degumming efficiency, and can be used for processing and degumming the Apocynum venetum bast.

Description

technical field [0001] The invention relates to the field of hemp fiber processing, in particular to a method for degumming apocynum bast. Background technique [0002] In the 21st century, with the improvement of living standards and the enhancement of health awareness, people's requirements for clothing have also developed from the previous cover to avoid the cold to pay more attention to the green natural and healthy environmental protection of textile materials. Apocynum is just such a natural, green and healthy textile raw material. In addition to the common characteristics of ordinary hemp fibers such as crispness, smoothness, high strength, good air permeability and moisture permeability, apocynum also has silky luster and good hand feeling, and is resistant to moisture and corrosion. What's more valuable is that Apocynum apocynum is also an ingredient of Chinese herbal medicine with a long history of medicinal value. Textiles made of apocynum not only have good han...
