Problems solved by technology

[0002] At present, the fine processing of hemp fiber, especially the fine processing of jute, kenaf, sisal and other hard and thick fibers has always been a problem that people are difficult to solve. The processing and preparation method of hemp fiber in the prior art, namely The treatment method consists of three steps: retting step, chemical degumming step, mechanical opening step, but in fact the flexibility and spinnability of the jute fiber obtained by this preparation method are still not ideal, and it is used in high-grade clothing fabrics. The performance in the application of hemp fiber is even worse. In the existing treatment technology for hemp fiber, emulsifiers, amino silicone oil or other softeners are generally used as the oil-giving substances of hemp fiber, which can only act on the surface of hemp fiber. This is also the reason why the fiber fineness of hemp fibers such as jute, kenaf, and sisal cannot achieve the desired result after refined treatment.

Embodiment 1

[0020] Step 1: After the raw hemp is subjected to a water bath or an acid bath, a sodium hydroxide solution is used for chemical degumming treatment.

[0021] Step 2: using pectinase or laccase to carry out biological enzyme degumming.

[0022] Step 3: Carry out fiber expansion treatment to the fiber by using a composite expansion aid, wherein the composite expansion aid is composed of a penetrating agent, an expanding agent, and an auxiliary agent for dissolving colloidal components in the fiber, and its mass ratio is 1:1:1; The additives for the colloidal component in the fiber include concentrated sulfuric acid, sodium hydroxide and biological enzymes with a concentration of 85%. When the composite expansion aid is treated, the composite expansion aid must be diluted into an aqueous solution with 10 times of water, and then the water ratio The ratio is 1:20, the temperature is 50°C, and the time is 0.5 hours to process the hemp fiber.

Abstract

The invention discloses a refining processing method of fibrilia. The method comprises the following steps of: performing water bath or acid bath on crude hemp; performing chemical degumming treatment by use of sodium hydroxide solution; performing bio-enzyme degumming by use of pectinase or laccase; performing fiber expansion treatment on the fiber by use of a composite expansion auxiliary; performing mechanical refining treatment on the fibrilia after the expansion treatment; and finally, sequentially washing, dehydrating and airing the fibrilia to obtain the refined fibrilia. Through the invention, the cohesive force among single fibers is weakened, the overall structure of the fiber becomes looser, and meanwhile, the surface smoothness of the fiber is improved so that the fiber cleaves or slides more easily under the effect of external force, thereby improving the effectiveness of mechanical effect and enhancing the fiber fineness and strength.
