Compound biological enzyme degumming method for ramie

Abstract

The invention discloses a compound biological enzyme degumming method for ramie. The method mainly comprises: sequentially carrying out treatments of ramie cutting, bundle trussing, soaking with hydrogen peroxide, soaking with warm water, cage filling, immersion in enzyme, fermentation, boiling, ramie bundle beating, pickling, water washing, dehydration, ramie shaking, oil preparing, oiling, deoiling and drying on raw ramie, and carrying out packaging and warehousing on the dried refined ramie. The method of the present invention has the following advantages that: a degumming process is simple, a period is short, the whole process has characteristics of easy control and no pollution, production cost is low, the prepared refined ramie has characteristics of stable and reliable quality, and substantial improvement of combing and spinning performance, wherein a finished product rate is more than 67%.

Description

technical field [0001] The invention relates to a method for degumming ramie compound biological enzymes. Background technique [0002] Ramie is a natural textile fiber. Ramie products have excellent properties such as scratching, moisture absorption, coolness, and ventilation. The majority of consumers favor it. With China's entry into WTO, China's textiles will occupy a larger share in the international market. The hot sales of hemp products will lead to a shortage of hemp raw materials. This has been reflected in recent years. Raw materials in the ramie industry The cost price is as high as 10,000 yuan / ton. According to the statistics of the National Textile Federation, the consumption of domestic hemp products has increased by 2.5 times in the past ten years. Ramie products are not only used in civilian clothing, but also widely used in industry and military. The annual domestic demand About 60,000 tons, the sales market is very optimistic. [0003] Ramie fibers exist ...

AI Technical Summary

Problems solved by technology

Some strains have low enzyme activity and poor degumming effect, generally only 30-40%, or because the strains are easily polluted, the enzyme activity decreases, the process is not easy to control, and the degumming effect is unstable

Hunan Yuanjiang Ramie Textile Factory has also done some research. The degumming of the cultivated strain T85-260 is actually a compositional property of the pre-degumming process. What is used is Bacillus subtilis. After degumming, the glue content of dry hemp is still 11%-15%, or even higher, and the shortest time is 6-8 days, and the preparation conditions are relatively harsh and complicated, so no mature, A process that can be used for industrialized mass production
