Structural phase transition type radial shrinkable tube fabric and its preparation method and application

Abstract

The invention discloses a structural phase transition type radially shrunk and dilated tubular fabric and its preparation method and application in long and thin strip type sampling key parts or sample collection bags. The tube fabric is a tubular-structure fabric which can be radially shrunk and dilated and is formed by circularly introducing weft yarn and high-tension warp yarn into a double-layer fabric for interweaving and forming. The preparation method includes the following steps that the warp yarn and the weft yarn are prepared for weaving on a machine, and weaving equipment adopts a shuttle loom; in the design process, face weaves and back weaves both adopt simple weaves as basic weaves; a straight arrangement method or a grouped draw-in method are adopted for drafting; face warp yarn and back warp yarn on the same group penetrate through the same dent; a weaving method of the double-layer fabric is adopted, and the structural phase transition type radially shrunk and dilated tubular fabric is thus obtained. The prepared tubular fabric is ingenious and stable in structure, high in toughness, high in modulus, easy to prepare, high in pulling-out property and low in tensile elongation rate; when the tubular fabric serves as the sampling parts and the sample collection bags, the sampling rate is high, the original grain information can be better maintained, and a sample missing phenomenon does not occur.

Description

technical field [0001] The invention belongs to the technical field of textile design and tubular fabric weaving, and relates to a tubular fabric with high drawing smoothness and low tensile elongation when stretching takes place along the inner and outer walls of a slender straight circular tube when the pulling movement occurs. and its forming technology. 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. There is no research on the tube fabric with smoothness and low tensile elongation and its forming technol...
