Problems solved by technology

When this method is used in production, if the process is properly controlled, it has a unique degreasing function and low production cost, but the production cycle is long, labor productivity is low, odor is generated during the production process, sanitary conditions are poor, and the residual rubber rate of raw materials is low. Low, unstable product quality

Abstract

The biological oil removing process for silk spinning material belongs to the field of primary processing of textile material. Oil eliminating bacteria strain taken from refrigerator is activated and set inside oil eliminating tank together with the silk spinning material for treatment of 30-50 hr. Inside the oil eliminating tank, there are bath ratio of 1 to 20-60, temperature of 30-45 deg.c, pH value 6.0-8.0, and oil eliminating bacteria liquid inoculating amount of 10-100 % that of liquid inside the tank. The present invention has the oil eliminating bacteria strain acting directly on the silk spinning material and propagating in scouring liquid in great amount. The present invention has optimized technological parameters to eliminate oil and grease from silk spinning material effectively.

Description

technical field [0001] The invention relates to a biological oil removal process for silk spinning raw materials, which belongs to the technical field of primary processing of textile raw materials. Background technique [0002] The scouring of silk spinning raw materials is to remove most of the sericin, grease, impurities, etc. in the raw materials, give full play to the inherent luster and feel of silk fibers, and at the same time maintain the original physical and mechanical properties of silk fibers as much as possible. The quality of scouring directly affects whether the subsequent process can be carried out normally, the quality of products and the level of production costs. The difference in scouring methods affects the labor intensity of workers, the working environment and environmental pollution. [0003] At present, the scouring methods commonly used in the production of silk spinning industry include: soap-alkali method, decay scouring meth...
