Embodiment Construction

[0035] The hemp two crude fiber is cut off on the fiber cutting machine, and the fiber length of cutting is 70mm. Then put the cut fibers into the disc of the cleaning machine for opening and cleaning. Then put the processed fiber into hemp boiling tanks, about 200 kg per tank. Use a crane to hoist the fiber-filled hemp pot into the high-temperature and high-pressure dyeing machine. Then pour the hot water in the auxiliary tank into the cooking hemp tank. The fibers are washed. 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 cooking solution prepared in the attached tank into the sesame cooking tank. Cover and seal. Then the boiling liquid in the tank is heated to 130°C. The cooking time is 2 hours. The sodium hydroxide content in the cooking liquid is 8g / L, the hydrogen peroxide content is 4g / L, and the sodium silicate content is 2g / L. After the h...

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...
