Problems solved by technology
[0009] In order to overcome the deficiencies in the background technology, the present invention provides a production process for front cowhide, which mainly solves the problem of low flocking fastness, uneven distribution of flocking density, low softness and water resistance in the current front cowhide 1. The surface leather effect is not good. The production process of the front cowhide is simple and reasonable. The vacuum suction roller is used to strengthen the depth of the fluff inserted into the water-based glue, which improves the stability of the flocking leather before it enters the baking process. Vacuum cooling Further strengthen the bond between the adhesive, synthetic leather base fabric, and fluff. The softness of the softener is increased from small to large, which improves the effect of the softener and makes the front cowhide more comfortable and soft. The front surface produced by this process Cowhide fleece has high flocking fastness, uniform distribution of flocking density, good softness and water resistance, and the surface leather effect is good, which has good economic and social benefits

Embodiment Construction
[0041] Below the embodiment of the present invention is described further:
[0042] Such as figure 1 Shown, a kind of production technology of front cowhide, it carries out as follows:
[0043] (1) Sizing
[0044] The front of the synthetic leather base cloth is evenly coated with PU resin water-based glue;
[0045] (2) Flocking
[0046] Through the flocking device, the granular cowhide is inserted vertically into the PU resin water-based glue on the base fabric, and the high-voltage electrostatic generator of the flocking device generates static electricity of 10,000 volts;
[0047] (3) Pre-baking
[0048] The front cowhide is pre-baked in a 20-meter 80°C oven to evaporate organic solvents and water;
[0049] (4) Vacuum suction
[0050] The front cowhide passes through the vacuum suction roller, the vacuum suction area is below the contact surface between the synthetic leather base fabric and the vacuum suction roller, the suction direction is vertically downward, and t...

The invention relates to a production process of front cowhide. It mainly solves the problems of low flocking fastness, uneven distribution of flocking density, low softness and water resistance, and poor leather effect on the surface of the current front cowhide. The production process of the front cowhide includes the following steps: (1) sizing; (2) flocking; (3) pre-baking; (4) vacuum suction; (5) baking; (6) vacuum cooling; 7) Brushing; (8) Microdermabrasion; (9) Kneading and softening; (10) Inspection, rolling and packaging. The production process of the front cowhide fleece is simple and reasonable. The front cowhide fleece produced by this process has high flocking fastness, uniform flocking density distribution, good softness and water resistance, and the surface leather effect is good. It has good economic benefits and social benefits.
Description
technical field [0001] The invention relates to the technical field of flocking, in particular to a production process of front cowhide. Background technique [0002] The concept of flocking is to vertically fix fiber powder (short fibers obtained by grinding or cutting waste fibers) on objects or substrates coated with adhesives (such as plastic, wood, rubber, leather, paper, cloth, etc.), This method of fixing short fibers is called flocking. The front cowhide is made by mixing genuine leather powder or leather on the PU / PVC leather base cloth and blending chemical raw materials. The flocking of the base fabric has the effect of imitation leather. People are welcome. [0003] At present, the front cowhide often has the following quality problems: [0004] 1. The flocking fastness is not high, which is easy to cause hair loss; [0005] 2. The flocking density distribution is uneven, and the suede surface is ugly and causes defects; [0006] 3. Softness and water resist...
