Structural phase transition radial expansion tube fabric based on soft weft and its preparation

Abstract

The invention provides a structural phase transition type radial shrinkable tubular fabric based on soft weft yarns, a preparation method and application thereof. The structural phase transition type radial shrinkable tubular fabric based on soft weft is characterized in that it is a tubular structure capable of radial shrinkage formed by weaving back and forth in the form of double-layer fabric weaving weaving weaving weaving weft and warp Fabric, when the tubular structure fabric is wrapped on the outer wall of the round tube, under the action of stretching, the tubular structure fabric is subjected to the top expansion force of the outer wall of the round tube, and the weft can be naturally straightened and grown and flattened, The tubular structure fabric is transformed from the weft support surface to the warp support surface, and the diameter of the tubular structure fabric is increased, thereby reducing the drawing resistance when the tubular structure fabric is overwrapped. The tube fabric can be used as an elongated strip-shaped sampling part and a sample collection bag, and is used for stratum drilling sampling and sample collection of small solid rocks and soil samples found in space technology, geological surveys, and archaeology. The tube fabric has exquisite and stable structure, high toughness and high modulus, and is convenient for preparation.

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 is performed along the inner and outer walls of a slender straight circular tube and the tubular fabric 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 tube fabrics with smoothness and low tensile elongation and its forming technology, and tube...
