The development history of artificial synthetic leather

In the early 20th century, nitrocellulose lacquer cloth made by coating fabric with nitrocellulose sol was the pioneer of artificial leather. in the 1930s, industrialized production of polyvinyl chloride opened up new raw material resources for artificial leather and promoted the development of artificial leather production. The paste made of polyvinyl chloride with plasticizer and stabilizer is easy to be colored, and after the coating is gelatinized, it can be made into many kinds of products with appearance similar to leather by printing, embossing or embossing and printing. Its breathability and moisture permeability are consistent with natural leather, and it has certain strength and abrasion resistance, especially it is easy to produce, abundant raw materials, uniform product quality, easy to cut and use, light weight, water resistance, low cost, so it is widely used in automobile interior decoration, car seats and other industrial accessories.

With the development of plastic varieties and processing technology, artificial leather forms a variety of series products. The raw materials of coating layer are polyamide, polyurethane, polyolefin, etc. Besides PVC, the raw materials of coating layer are also used. There are also many kinds of base fabrics, such as flat cloth, canvas, knitted cloth, pile cloth, non-woven cloth and so on. Different varieties and colors of artificial leather production also differ from the way of coating and gelation of the base fabric surface layer, as well as the order of finishing process, such as embossing, printing, surface treatment and the composition of surface treatment agent.

Production includes base fabric treatment, adhesive preparation, coating, laminating, gelation, surface treatment, embossing, cooling, and winding. There are 4 main production methods:

The adhesive material is directly coated on the pretreated base fabric with a squeegee, then it is gelled and plasticized in the plasticizing box, and then it is embossed and cooled to get the finished product. This method can produce all kinds of ordinary artificial leather, film artificial leather and foam artificial leather on fabric base.

asdadadTransfer coating method

Also called indirect coating method. The paste is coated on the carrier (release paper tape or stainless steel tape) with a reverse roller or scraper, and after gelation, the cloth base is then laminated on the gelated material layer under no tension, and then plasticized, cooled and peeled off from the carrier, and then post-treated, and the finished product is obtained. This method is suitable for the production of knitted fabric or non-woven fabric based foam artificial leather and common artificial leather.

According to the formula requirements, resin, plasticizer and other matching agents are measured and put into the kneading machine to mix evenly, and then sent to the three-roller or four-roller calender (see plastic machinery calendering into the required thickness and width of the film, and laminated with the pre-heated base cloth, and then embossed and cooled to get the finished product. This method can produce various kinds of artificial microfiber leather with different cloth base. In order to improve the lamination effect of base cloth and film, a layer of adhesive is often applied on the base cloth first.

asdadad Extrusion lamination method

The resin, plasticizer and other matching agents are mixed well in the kneader, and then extruded into a film layer of certain thickness and width by the extruder, and then laminated with the preheated base fabric on the three-roller shaping machine, and then finished products are obtained by preheating, laminating, embossing and cooling.

Bensen company production of environmental protection leather is actually artificial synthetic leather, mainly made of resin, such as: imported environmentally friendly polyurethane, polyurethane resin (TPU), etc., service life is actually longer than the leather. The advantages of the artificial leather produced by Bensen: First, the leather has good tensile strength, not easy to tear, more durable; second, corrosion resistance, good anti-abrasion performance; third, there is no unpleasant smell, and has antibacterial, anti-mildew, anti-moth, without any harmful substances, environmental characteristics.
