Problems solved by technology

[0005] The existing printing and dyeing process of this imitation memory fabric adopts two desizing and refining steps, although the dyeing effect of the gray cloth can be better, the color difference of the finished product is smaller, and the quality of the finished product is improved; For Huayao imitation memory fabrics, the time for two times of scouring and desizing is longer, and the shape memory function and high recovery deformation ability of half-elastic Huayao imitation memory fabrics are poor

Abstract

The invention discloses a dyeing and finishing processing method of a semi-elastic Huayao imitation memory fabric, and relates to the technical field of textile printing and dyeing, the method comprises the following steps: (1) flat-width desizing; (2) flat-cylinder refining; (3) dyeing; (4) pre-shrinking; and (5) forming, namely a fabric is subjected to soft forming through a forming machine, a softening agent TF-0404 A and a shaping auxiliary agent are added into the shaping machine, the mass ratio of the fabric to the softening agent TF-0404 A to the shaping auxiliary agent is 20: 1: 1, theforming temperature is 165-185 DEG C, the forming time is 30-50 seconds, and the width of the shaping machine is 153-155 cm; wherein the shaping agent comprises the following substances in parts by weight: 3-8 parts of dihydroxymethyl dihydroxy ethylene urea resin, 4-8 parts of polyurethane modified organic silicon, 3-6 parts of a strong fiber protective agent LH -034, 2-5 parts of a cationic amino silicone elastic fabric finishing agent and 3-6 parts of melamine formaldehyde resin. According to the method, the problems that the dyeing shape memory function and the shape recovery capability of the semi-elastic Huayao fabric are not high are solved. By means of the shaping auxiliary agent, the shape memory function and the shape recovery capability of the semi-elastic Huayao fabric can beimproved.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, more specifically, it relates to a dyeing and finishing method of a semi-elastic Huayao imitation memory fabric. Background technique [0002] Shape memory fabric is a kind of material with shape memory function, which is processed or introduced into the fabric in the form of weaving or finishing. Under certain external conditions, it has excellent shape memory, high recovery deformation, good shock resistance and adaptability. performance textiles. In the fabric polymer molecules, the stationary phase composed of crystalline phase and amorphous phase, and the reversible phase composed of partial crystalline structure that produces reversible changes in crystallization and crystallization melting work together to endow the fabric with shape memory function. [0003] All polymers with a stationary phase and a reversible phase have shape memory functions, such as polyester (PET...
