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 they do not continue to use chemical methods to assist, 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; and did not pay attention to the problem that microorganisms can modify fibers

Abstract

The invention discloses a preparation method of antibacterial environment-friendly mulberry bark fiber. The method is as below: conducting mechanical beating on the mulberry bark to remove impurities; then conducting pretreatment with the process of tea saponin 4-5 g / L, 3h, temperature of 80 DEG C, and bath ratio of 1:18; preparing Bacillus licheniformis, Bacillus subtilis, and EM bacteria in the ratio of 1:0.2:0.5 into a compound inoculant; uniformly spraying the inoculant on the pretreated mulberry bark, fermenting at 38 DEG C for 8 h, rapidly heating to 45 DEG C and maintaining for 2 s; then rapidly cooling to 39 DEG C, continuing fermentation for 2-3 h, and washing with warm water after fermentation; preparing an enzyme solution under the parameters of bath ratio of 1:15, 100-120 min, and temperature of 45 DEG C; and rinsing, carrying out routine soaping, loosing and drying.

Description

technical field [0001] The invention relates to an antibacterial and environment-friendly mulberry fiber, belonging to the technical field of textiles. Background technique [0002] Mulberry fiber is a kind of wild plant fiber, which has excellent moisture absorption, breathability, warmth retention and good antibacterial properties, and is biodegradable. It has good luster, soft touch and easy dyeing. It is a high value-added pure natural fiber . 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 o...
