Example Embodiment

[0035] The hemp two crude fibers were cut on a fiber cutter, and the length of the cut fibers was 70 mm. Then put the cut fiber into the blower disc, open and remove impurities. Then put the treated fiber into the hemp pot, each pot is about 200 kg. Use a crane to hoist the hemp-boiled pot filled with fibers into the high temperature and high pressure dyeing machine. Then pour the hot water in the auxiliary tank into the hemp boiling tank. Wash the fibers. The washing time is 10 minutes. After washing, put the washing water back into the circulating pool. Then put the sodium hydroxide, hydrogen peroxide and sodium silicate boiling liquid prepared in the attached tank into the hemp-cooking tank. Seal with a cap. Then the boiling liquid in the tank is heated to 130°C. The boiling time is 2 hours. The content of sodium hydroxide in the cooking liquor is 8g / L, the content of hydrogen peroxide is 4g / L, and the content of sodium silicate is 2g / L. After the hemp is boiled, the waste liqu...

Abstract

A processing method of a secondary category hemp crude fiber relates to a spinning treatment method of secondary category hemp crude fiber (that is, falling matters of hemp skin and stems separation). The existing method adopts an alkali cooking method, which can not get ideal effect, and the others comprise alkali and sodium sulfide method, while the discharged wastewater can pollute environment. The technique of the invention comprises pre-gluing treatment, chemical ungluing treatment and after-gluing treatment. The chemical ungluing treatment adopts softener to do softening treatment and to cultivate, and then carding is carried out and the process is finished. After being treated by the method of the invention, the hemp crude fiber of secondary category has great improvement in spinning property and dyeing property with perfect effect, which not only improves economic value of the secondary category crude fiber, but also has no pollution to environment for the produced wastewater is easy to be purified; therefore, the processing method of secondary category hemp crude fiber is an ideal treating method.

Description

technical field [0001] The invention relates to a method for processing the hemp bicrude fiber, that is, the separated and fallen matter of the hemp bark. The fibers obtained after treatment can be blended with cotton fibers to produce fine hemp / cotton blended yarns. Background technique [0002] Hemp fiber is one of the earliest textile fibers used by humans and was first cultivated in China. With the advent of the drug marijuana, the use of hemp fiber has come to a standstill. After entering the 1990s, with the improvement of people's awareness and the increasing demand for green textiles, hemp, as an ecological textile raw material, has once again attracted people's attention. Because the fabric containing hemp fiber not only has good air permeability, moisture absorption and moisture release, but also has natural antibacterial health care, anti-ultraviolet radiation and sound absorption and absorbing functions. At present, the original microbial degumming technology i...
