Problems solved by technology

However, the leather processing process is very complicated, and the process that needs to be passed through to make finished leather is roughly as follows: soaking raw hide in water--fleshing--degreasing--hair removal--soaking in alkali--expansion-- -Deliming----Softening----Pickling----Tanning----Splitting----Shaving----Retanning----Neutralization----Dyeing-- --refueling-----filling-----drying--finishing--finishing--finished leather, the process is complicated and the manufacturing cost is high, so the price of leather products is often high, so that Ordinary people beyond reach
Therefore, products such as artificial leather, synthetic leather, and regenerated leather have appeared on the market, but these imitation leather products are difficult to meet people's requirements in terms of hand feel, air permeability, and durability, and the quality of such products is uneven. It is easy to cause pollution, and some products may even cause harm to the human body and bring hidden dangers to human health.

Embodiment 1

[0023] The specific preparation process of the fabric is as follows:

[0024] a) Prepare the base layer. The raw material of the base layer is polyester, spandex blended fiber and cotton fabric, and the base layer fabric is woven by knitting process according to the ratio of 2:11.

[0025] b) Coating the adhesive layer, the adhesive layer is thermosetting viscose fiber material, after melting, use a scraper to coat the base fabric, the thickness of the coating is controlled at 0.03mm, and the baking temperature after coating is controlled at 30°C , and the time is 20 minutes; the viscose layer produces a bonding effect at a temperature of 50°C-60°C, has excellent air permeability at room temperature, and has good elasticity, which is used to improve the elasticity and strength of the fabric, and at the same time ensure that it is compatible with the imitation leather layer. good bonding.

[0026] c) To prepare the imitation leather layer, firstly, select the ingredients of th...

Embodiment 2

[0030] The specific preparation process of the fabric is as follows:

[0031] a) Preparation of the base layer. Nylon 66 fiber and cotton fabric are selected as raw materials for the base layer, and the warp and weft thread weaving process is used to weave the base layer fabric according to the ratio of 3:10.

[0032] b) Coating the adhesive layer, the adhesive layer is thermosetting viscose fiber material, after melting, use a scraper to coat the base fabric, the thickness of the coating is controlled at 0.03mm, and the baking temperature after coating is controlled at 35°C , and the time is 25 minutes; the viscose layer produces a bonding effect at a temperature of 50°C-60°C. good bonding.

[0033] c) To prepare the imitation leather layer, first, select the ingredients of the imitation leather layer 3 and make the ratio according to the following percentages: genuine leather powder 72%, vinyl silicone resin 10%, complex 3%, diluent 3%, inhibitor 4%, 8% color paste; then, ...

Abstract

The invention relates to a method for processing an imitation leather fabric, which comprises the following steps: a) preparing a base layer, b) coating a bond coat, c) preparing an imitation leather layer, d) carrying out thermosetting profiling on the imitation leather layer, e) baking and fixing. The invention discloses the method for processing the imitation leather fabric, by reasonable material selection and scientific processing technology, the prepared fabrics possess soft touch and elasticity, the imitation leather layer has abundant color, can print bump pattern and enrich the appearance of clothes, and has the advantages of high fabrics strength, good antifouling performance, high cost performance and wide application.

Description

technical field [0001] The invention relates to a fabric processing technology, in particular to a low-cost, high-performance imitation leather fabric processing technology, which belongs to the technical field of fabric fabrics. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. The market potential of leather and its products is huge. The total global demand for leather is about 100 million square meters, which is equivalent to the output of 300 million pieces of cowhide (standard leather). China’s leather output is equivalent to nearly 70 million pieces of standard leather, accounting for about 23.33% of global leather production. However, the leather processing proces...
