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 actu

Example Embodiment

[0037] Example 1: The method for degumming ramie with compound biological enzymes includes the following steps:

[0038] (1) Cut the hemp and tie the hemp: untie the hemp knots in the original hemp, and remove the dry hemp and short hemp, then straighten the original hemp, separate the head and the tail, and tie them into 2.5-3.5 kg hemp;

[0039] (2) Hydrogen peroxide soaking: Put 4.5-5.5 kg of hydrogen peroxide, 0.9-1.1 kg of deoxygenase and 2.8-3.2 tons of clean water into the cement pool, and keep the water temperature at 18-22℃, and put the tied mah into the pool to soak 13- 18 hours to restore the ramie to its harvest characteristics;

[0040] (3) Warm water soaking: Put the ramie soaked in hydrogen peroxide into an iron box, put it in clean water, and soak at a temperature of 55-65℃ to fully swell the ramie;

[0041] (4) Cage installation: hang the soaked ramie loosely on the hemp cage, each cage ramie weighs 480-520 kg;

[0042] (5) Enzyme soaking: configure the biological enzy...

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 ...
