Problems solved by technology

[0002] Apocynum, also known as wild hemp, Zeqima, etc., belongs to Apocynaceae. It is famous because it grows on the Lop Nur plain. It is a wild high-grade textile fiber plant. The length of apocynum fiber is similar to that of cotton fiber, and the fiber has a soft luster. White and soft texture, but because the fiber surface is smooth, there is no curl in the longitudinal direction, the cohesion force is small, and the tensile fracture performance is low, so it is easy to scatter during spinning and difficult to form a net, which greatly reduces the performance and quality of its textiles. ; Therefore, inventing a method for improving the tensile fracture performance of apocynum fiber can greatly improve the use quality of its textiles

Abstract

The invention belongs to the technical field of apocynum fiber treatment and particularly relates to a method for improving tensile fracture performance of apocynum fiber. The method comprises specific steps as follows: (1) the apocynum fiber is soaked in a potassium fulvate water solution, the mixture is continuously heated over slow fire after being boiled over slow fire, and the apocynum fiberis taken out, frozen in a freezer and the taken out; (2) the apocynum fiber is subjected to steam treatment and microwave drying and soaked in a reinforcing agent, and a filter agent is fished out; (3) the apocynum fiber is subjected to vacuum treatment, taken out and freeze-dried. The cohesive force between fiber is effectively enhanced, the tenacity of the fiber is effectively improved, the spinnability is enhanced, breaking in the processing process is not easily caused, the roll winding and spinning strength is improved, the situation of broken filaments due to non-uniform stretching or fracture of monofilaments is effectively avoided, fewer broken filaments break, the hand feeling of textile fabric is remarkably improved, and the textile fabric touches soft, has excellent processibility and stiff wearability, can resist higher impact and deformation and has improved moisture-proof performance and the bacteriostasis rate of 85.6% or above.

Technical field [0001] The invention belongs to the technical field of apocynum fiber processing, in particular to a method for improving the tensile fracture performance of apocynum fiber. Background technique [0002] Apocynum venetinum, also known as wild hemp, Zeqiu hemp, etc., belongs to the Apocynaceae family. It is famous because it grows on the Lop Nur Plain. It is a wild high-grade textile fiber plant. The length of apocynum fiber is similar to cotton fiber, and the fiber has a soft luster. It has the characteristics of whiteness and soft texture, but due to the smooth surface of the fiber, no longitudinal curl, small cohesion force and low tensile breaking performance, it is easy to disperse during spinning and difficult to form a net, which greatly reduces the performance and quality of its textiles ; Therefore, inventing a method to improve the tensile breaking properties of apocynum fiber can greatly improve the quality of its textiles.
