What is the difference between PU Oxford cloth and PVC Oxford cloth? First of all, what they have in common is that they are all coating types. PVC leather and PU leather are collectively called artificial leather. PVC and PU are both polyvinyl chloride. PU feels soft and PVC feels hard. The difference between the two lies in the manufacturing process. Let’s take a closer look at the process differences between the two:
PVC coating process: During the manufacturing process of PVC leather, plastic particles must first be hot-melted and stirred into a paste. It is evenly coated on the Oxford cloth base according to the specified thickness, and then enters the foaming furnace for foaming, so that it has the softness to adapt to the production of various products and different requirements. Surface treatment (dying) is performed at the same time as it comes out of the oven. , embossing, polishing, matting, grinding and fluffing, etc., mainly in accordance with specific product requirements).
PU coating process: The manufacturing process of PU leather is more complicated than that of PVC leather, because the base fabric of PU is tensile strength Good canvas PU material can not only be coated on the top of the base fabric, but also include the base fabric in the middle, so that the existence of the base fabric cannot be seen from the outside. The physical properties of PU leather are better than PVC leather, including resistance to bending, good softness, high tensile strength, and breathability (not available in PVC). The pattern of PVC leather is hot-pressed by a steel pattern roller; the pattern of PU leather is hot-pressed on the surface of the semi-finished leather with a pattern paper, and then the paper leather is separated after it cools down to make the surface. deal with. The price of PU leather is more than double that of PVC leather, and the price of PU leather with certain special requirements is 2-3 times higher than that of PVC leather. Generally, the pattern paper required for PU leather can only be used 4-5 times before being scrapped; the pattern roller has a long service life, so the cost of PU leather is higher than that of PVC leather.
Suzhou Textile Co., Ltd. is fully committed to the production and development of Oxford cloth, luggage cloth and special fabrics. It can be processed according to samples, and can also be waterproof, velvet-proof, PA, etc. according to customer needs. PU, urea, flame retardant, anti-UV, DuPont three-proof, gold and silver pearlescent coating, oily waxy coating, breathable and moisture-permeable coatings, and various post-finishing treatments such as PVC calendering and foaming, the product has obvious competitive advantages . </p
