Ultra-fiber has been widely used in sports, leisure life and industrial products and many other fields, including footwear, sofas, bags, gloves, clothing, soft bags, automotive interiors, medical equipment, sporting goods, etc.
Ordinary people will be leather other than synthetic leather such as: PVC, PU leather collectively referred to as artificial leather or imitation leather. PVC and PU are all polyvinyl chloride (one kind of plastics), but the manufacturing process of the two products is different. PVC leather in the manufacturing process to first the plastic particles hot melt stir into a paste, according to the prescribed thickness evenly coated on the base of T/C needle weaving, and then into the foaming furnace, so that it has the ability to adapt to the production of various products, different requirements of the soft, in the oven at the same time surface treatment (dyeing, embossing, polishing, extinction, grinding, etc., mainly in accordance with the specific product requirements).
Pu leather is more complicated than PVC leather in manufacturing process, because PU substrate is a good tensile strength of canvas PU material, in addition to coated on the top of the cloth, but also can be covered in the middle of cloth, so that the appearance of the existence of the cloth. The physical properties of PU leather are better than PVC leather, with twists and turns, good softness, high tensile strength and breathability (PVC none). The pattern of PVC leather is made by pressing the steel pattern roller; Pu leather's pattern is used a pattern paper first hot paste in the semi-finished leather surface, waiting to cool down after the separation of paper leather, do surface treatment. PU leather price than PVC leather more than 1 time times higher, some special requirements of PU leather price than PVC leather 2-3 times higher. PU Leather general needs of the pattern paper can only be used 4-5 times, the use of the pattern roller is long, so the cost of PU leather is higher than PVC leather.
