A flexible auxetic fabric with adjustable scale and shape memory and its manufacturing method

Abstract

The invention relates to an adjustable scale and shape memory flexible stretching fabric and a manufacturing method thereof. The method includes the following preparation processes: 1) unwinding yarns formed by compounding heat-settable filament yarns, shape memory filament yarns and third component fibers from a creel, arranging the yarns into stretching patterns by a yarn guide and solidifying the stretching patterns in a physical mode; 2) enabling the fabric to achieve shape keeping property in stretching effect during repeated use by the shape memory filament yarns, and enhancing touch and visual style, transparency, density and compactness of the fabric by the third component fibers; 3) forming an adjustable scale flexible stretching fabric or reducing the size of the stretching fabric to form a shape memory flexible stretching fabric. The flexible stretching fabric has the advantages that the flexible stretching fabric has stretching property and shape memory property, can be used for garments particularly maternity dresses and children's dresses, and can also be used for wrapping sleeves, isolation protection pads, filtering materials, sound absorption or insulation materials, composite materials and the like.

Description

technical field [0001] The invention relates to a method for continuously preparing a structurally stable flexible auxetic fabric with shape memory and adjustable size, which can be used in the fields of clothing isolation protective pads, filter materials, sound-absorbing or sound-insulating materials, composite materials, etc., and belongs to textile and clothing fabrics field of processing technology. Background technique [0002] Shape memory functional fabric refers to the fabric with shape memory function, also known as memory cloth, or shape memory cloth. It is malleable and soft to the touch without worrying about damage from creases. Garments made of this fabric can independently maintain any shape and present any folds without external support, and can be completely restored to a flat state after being flicked by hand without leaving any creases, and the shape retention is permanent. At present, the shape memory fabrics on the market are mostly made of shape memo...

Problems solved by technology

[0005] Although the above-mentioned auxetic fabrics use fibers or yarns in the preparation process, the main process is still based on the traditional knitting process. Although the fabric products have an auxetic effect, the structure is loose and the deformation is too large, and the product is stable during repeated use. Poor performance, very limited application prospects
