Embodiment Construction

[0014] In order to make the technical solution of the present invention more clear, the present invention will be further described in detail in conjunction with the following examples. It should be understood that the specific embodiments described here are only used to explain the invention, and are not intended to limit the present invention.

[0015] The present invention provides a kind of preparation method of novel imitation leather environment-friendly fabric, comprises the following steps:

[0016] A. Twist thermoplastic polyurethane filaments and polyester yarns with a count of more than 500D in parallel structure, and the ratio of the number of hot-melt yarns to polyester yarns is 1:1.5-3, that is, one hot-melt yarn Match 1.5-3 polyester yarns, interlace hot-melt yarns and polyester yarns to form semi-finished fabrics;

[0017] The proportional relationship between the two yarns determines the effect and thickness of the final imitation leather fabric. The structure...

Abstract

A preparation method of a novel imitation leather environment-friendly fabric is characterized in that thermoplastic polyurethane filaments and polyester yarns are subjected to parallel structure stirring and twisting, the upper portion and the lower portion of a semi-finished product fabric are each cushioned with a layer of high-temperature-resistant teflon cloth, then hot pressing is carried out, the hot pressing temperature is 120 DEG C, the semi-finished product fabric is turned over, secondary hot pressing is performed on the back surface of the semi-finished fabric to form a fabric finished product. The fabric designed through the novel steps solves the waterproof problem of traditional fabrics, and the novel leather-imitating environment-friendly fabric is waterproof and windproof, has the hand feeling and function of leather, has richer color design and pattern change, is superior to the leather itself in artistic expression, is high in folding strength at low temperature, and has strong tearing resistance after being repeatedly folded. The novel leather-imitating environment-friendly fabric is easy to sew, low in cost and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of environment-friendly material design, in particular to a method for preparing a novel leather-like environment-friendly fabric. Background technique [0002] Green environmental protection is an important development trend in the future. Animal resources also need to be continuously protected. Traditional fabrics are generally non-woven fabrics, traditional fabrics or leather. Non-woven fabrics are composed of point-oriented or random fibers, such as polypropylene. (PP) pellets as raw material. Traditional fabrics generally have the following disadvantages: [0003] The waterproof performance of traditional fabrics is poor, and the hand feeling is not good. The leather does not have rich patterns and colors. In addition, the traditional leather has low folding degree at low temperature, cannot be folded repeatedly, and is not resistant to tearing. Contents of the invention [0004] In view of the problems in th...
