Problems solved by technology

The most environmentally friendly method is physical processing, but this method has low efficiency and poor effect
At present, the chemical degumming method is generally used in China, but this method causes a certain degree of damage to the fiber, consumes a lot of chemicals, energy and water in the production, and the labor intensity of the workers is high, polluting the environment
[0004] In the prior art, people have used acid pretreatment and degumming enzyme to degumming the mulberry fiber, but if the assistance of chemical methods is not continued, the colloid content in the mulberry sample is still as high as about 30%
It is generally believed in the prior art that the industrial production and application of biological enzyme degumming of mulberry bark is not yet mature. research stage

Abstract

The invention discloses a rapid mulberry bark biological degumming process. Picked mulberry bark is pretreated. The treatment process includes the steps that tea saponin ranges from 4 g / L to 5 g / L, time is 3 h, temperature is 80 DEG C, and the bath ratio is 1:18; bacillus licheniformis, bacillus subtilis and EM bacteria are prepared into a complex microbial inoculant according to the quantity ratio of 1:0.2:0.5; the microbial inoculant is evenly sprayed to the pretreated mulberry bark, and after being fermented for 8 h at the temperature of 38 DEG C, the mulberry bark is rapidly heated to 45 DEG C, the temperature is kept for 2 s and then rapidly cooled to 39 DEG C, continues to be fermented for 2-3 h, and is completely washed with warm water after fermentation is finished; an enzyme solution is prepared, wherein the treatment parameters are characterized in that the bath ratio is 1:15, time ranges from 100 min to 120 min, and temperature is 45 DEG C. The biological fermentation process and bio-enzyme treatment are fully utilized, especially unique heat shock treatment is used in the fermentation process, the mulberry bark can be rapidly degummed, and the gum content of the treated mulberry bark can be controlled to be 40% or below.

Description

technical field [0001] The invention relates to a rapid biological degumming process of mulberry bark, belonging to the technical field of textiles. Background technique [0002] Mulberry fiber is a new type of natural fiber developed in recent years. It has good luster, soft touch and easy dyeing. Compared with cotton fiber, mulberry fiber has better moisture absorption, moisture permeability, wrinkle resistance, wear resistance and warmth retention, and is a typical ecological fiber. China is a big country of sericulture and silk, and the planting area of ​​mulberry trees is wide. The pruning of mulberry trees in winter and summer every year will produce a large number of discarded mulberry branches. The use of mulberry bark can develop original mulberry fiber textiles, which is conducive to the comprehensive utilization of sericulture resources. Textile product development offers room for innovation. The quality of mulberry fiber is mainly affected by mulberry species, ...
