Abstract

The invention discloses a friction-unlocking self-rotating radial contraction-expanding tube fabric and a preparation method thereof and its application in elongated belt-shaped sampling key components or sample collection bags. The tubular fabric is woven with angular symmetry and frictional self-locking intersecting threads to stabilize the warp yarns, thereby forming a radially expandable tubular structural fabric. The preparation method is as follows: prepare warp yarns and cross threads and put them on the machine; the weaving equipment adopts a circular knitting machine; the warp yarns are densely arranged in parallel on the circular knitting machine; Weaving with warp yarns to obtain friction unlocking self-rotating radial shrinkable tube fabric. The pipe fabric prepared by the present invention has exquisite and stable structure, high toughness and high modulus, and convenient preparation; it has high drawability and low tensile elongation; ③ when used as a sampling part and a sample collection bag, it has a higher sampling rate, The original bedding information can be well maintained without loss of sample.

Description

technical field [0001] The invention belongs to the technical field of textile design and tube fabric weaving, and in particular relates to a tube with high smoothness of drawing and low tensile elongation when pulling back and forth along the inner and outer walls of a slender straight circular tube under the action of stretching Fabrics and their forming techniques. Background technique [0002] At present, there are many reports on the technology and processing technology of tube fabric forming, and there are also some studies on preparation methods and preparation tools. Most of them focus on the traditional structural tube fabrics formed by weaving, knitting, and weaving. There are few studies on tube fabrics with variable structure functions, especially the high-drawing motion of the inner and outer walls of the slender straight circular tube under the action of stretching. Tube fabrics with smoothness and low tensile elongation and their forming techniques, and no re...
