Production method of zero-dermatoglyph imitation leather composite sofa fabric

Abstract

The invention discloses a method for making a composite sofa fabric imitating cowhide with zero-point leather pattern. The composite sofa fabric imitating cowhide with zero-point leather pattern is composed of a suede surface layer, a linen middle layer and a single-face fleece bottom layer. The manufacturing method is as follows: first The surface layer of suede is dyed, printed and bronzed. The dyeing temperature is 180-190°C, and then compounded with the middle layer of linen. The adhesive for compounding includes polyester polyol, butanol, bridge release agent and accelerator , the component ratio is 10:3.5:1.2:0.5, the compounding temperature is 220-230°C, after compounding, let it stand for 24 hours, then wash and dry; finally compound with the bottom layer of single-sided fleece, compound adhesive II Including polyester polyol and ethanol, the composition ratio is 10:3.5, and the compounding temperature is 220-230°C. The invention has the texture and texture of real leather, the texture of the fabric is comfortable, warm in winter and cool in summer, has good air permeability and is easy to take care of.

Problems solved by technology

[0002] At present, with the continuous development of social and economic life, people's living standards continue to improve, and people's requirements for the quality of life are getting higher and higher, especially for home textiles and decorative fabrics such as sofas, curtains, and bedding. The higher the price, especially the leather sofa fabrics, but because the supply of leather sofa fabrics is scarce and the price is expensive, in order to solve the environmental pollution and animal protection problems caused by natural leather, many imitation leather sofa fabrics appear on the market, and the common imitation leather fabrics are made directly. The process of coating or transfer coating makes it have the luster of genuine leather, with a thick and elastic feel, but the direct coating is affected by the texture of the fabric, and its appearance is far from that of genuine leather, and the transfer coating product solves this problem The problem is that its appearance is very similar to real leather, but due to the limitations of its production process, the raw material release paper needs to be imported, and the cost is relatively high

Moreover, the release paper transfer coating uses a continuous coating process, which makes the coating too regular and causes the product to have air permeability problems; and the current transfer coating production has a certain impact on the environment, and the requirements for environmental protection facilities are also high.

Although transfer-coated imitation leather fabrics can be used in clothing and home textiles, there are always disadvantages of being stuffy and airtight, and the fabric is not durable due to the effect of additives

There are also some artificial leather composite sofa fabrics, but due to the poor control of the composite process and composite temperature, it is impossible to produce good artificial leather composite sofa fabrics.
