Problems solved by technology

The existing suede-like finishing is usually carried out on the natural cotton base cloth for flocking or flocking and shearing. The manufactured suede-like fabric is only imitated in appearance. In terms of performance, it is especially Cold resistance, touch, air permeability, moisture permeability, etc. are not ideal, which limits the application field of suede fabrics, and the added value of the product is low

Embodiment 1

[0013] Embodiment 1: as figure 1 As shown, the manufacturing process of high-simulation suede fabric is: a. Weaving and pre-treatment: first use the loom to weave gray cloth, and then carry out fiber opening, shaping, napping and shearing pre-treatment on the gray cloth, b. PVA impregnation: in PVA The gray cloth is impregnated in the aqueous solution, the temperature of the PVA aqueous solution is controlled at 60°C, the impregnation speed of the gray cloth is 20 m / min, the pressure between the rolling pipes through which the impregnated cloth passes is 0.01MPa, and the drying temperature is controlled at 130°C, c .PU impregnation: In the mixture of PU resin and DMF, the gray cloth is impregnated with PU. The impregnation speed of the gray cloth is controlled at 15 m / min. The pressure between the rolling pipes through which the impregnated cloth passes is 0.02 MPa. The impregnated cloth is coagulated by a coagulation bath, washed and dried, d. pre-dyeing treatment, the above-...

Embodiment 2

[0014] Embodiment 2: as figure 1 As shown, the manufacturing process of high-simulation suede fabric is: a. Weaving and pre-treatment: first use the loom to weave gray cloth, and then carry out fiber opening, shaping, napping and shearing pre-treatment on the gray cloth, b. PVA impregnation: in PVA The gray cloth is impregnated in the aqueous solution, the temperature of the PVA aqueous solution is controlled at 98°C, the impregnation speed of the gray cloth is 6 m / min, the pressure between the rolling pipes through which the impregnated cloth passes is 0.2 MPa, and the drying temperature is controlled at 180°C, c .PU impregnation: In the mixture of PU resin and DMF, the gray cloth is impregnated with PU. The impregnation speed of the gray cloth is controlled at 7 m / min. The pressure between the rolling pipes through which the impregnated cloth passes is 0.15 MPa. The impregnated cloth is coagulated by a coagulation bath, washed and dried, d. pre-dyeing treatment, the above-me...

Embodiment 3

[0015] Embodiment 3: every 100 kilograms of PVA aqueous solution is made up of mixing 2 kilograms of PVA and 98 kilograms of water. Every 100 kilograms of PU resin and DMF mixture is composed of 5 kilograms of PU resin and 95 kilograms of DMF. Every 100 kg of DMF aqueous solution is composed of 10 kg of DMF and 90 kg of water. Every 100 kilograms of dyeing pre-treatment cleaning agents are made up of 1 kilogram of scouring agent, 1 kilogram of penetrating agent, 5 kilograms of liquid caustic soda, 1 kilogram of deoiling spirit and 92 kilograms of water, and all the other are with embodiment 1 or embodiment 2.

Description

technical field [0001] The invention relates to a manufacturing process of a fabric, in particular to a manufacturing process of a simulated suede fabric. Background technique [0002] With the deteriorating living environment, human beings continue to occupy the living space of animals. Based on the lack of natural resources and the needs of animal protection, it is a trend and necessity to replace natural leather with synthetic materials. At present, in the field of leather application, the global market is actively developing environmentally friendly artificial leather. [0003] As a symbol of beauty, fashion and social status, suede is extremely valuable, but the use of natural suede is limited by factors such as output and price. In order to meet the needs of more consumers, people began to develop artificial suede and imitation suede products. The existing suede-like finishing is usually carried out on the natural cotton base cloth for flocking or flocking and shear...
