It can also form a layer of uniform covering rubber on the surface of the fabric, so as to achieve waterproof, windproof, breathable, and other functions. Commonly used coating foot strength There are PU glue, A/C glue, PE glue, DuPont protective coating, etc., and each glue will create different hand-feeling luggage fabrics.OEM backpack manufacturer,this time I will talk about the process of fabric coating for bags.

First: with a barrel

According to the requirements of fabric coating, the cloth will be separated according to the vat number written by the dyeing factory. The masters will clean the silk car to keep the silk car clean and prevent dust and stains from being adsorbed on the cloth. After that, put the fabrics one by one in the silk car, and so on until the silk car is paved.

Second: sea

Push the laid silk cart to the edge of the sewing machine, spread a piece of clean cloth on the ground between the silk cart and the sewing machine, put down the sewn ends to keep them clean, and connect the laid ends with the sewing machine. At this time, the masters will connect the ends of every two pieces of cloth to make it a whole piece of cloth, and connect the other two adjacent ends, and push the silk cart with the stitched ends to the front of the coating machine. Only then can the fabric be sewn accurately and neatly.

After preparation, first, adjust the silk car, then thread the leader cloth on the coating machine, connect the tail of the leader cloth with the upper end of the silk car with a sewing machine, start the machine, and open the position of the joint to the position of the coating knife location. Adjust the position of the pulp plate. When preparing the coating, the master mixes the slurry according to the requirements of the coating and the requirements of the process sheet formula and mixes the prepared slurry with a beater. After stirring evenly, it is ready for use. The temperature control switch reaches the specified temperature and heats up. After reaching the specified temperature, the ventilation is turned on. Pour the prepared slurry onto the bottom plate of the coating knife, start the machine, and start coating.
