Han leather, also known as PU, is a type of artificial leather. Upstairs said it was made in Korea, and it was simply hollowed out. Polyvinyl chloride and knitted fabric synthesis.
The base fabric of PU is a canvas PU material with good tensile strength, which is higher than imitation leather, but the waste product has no use value.
Most people will refer to synthetic leather other than genuine leather, such as PVC and PU leather, as artificial leather or imitation leather. PVC and PU are both polyvinyl chloride (a type of plastic), but the manufacturing process of these two products is different.
In the manufacturing process of PVC leather, the plastic particles should be hot-melted and stirred into a paste, evenly coated on the base of the T C knitted fabric according to the specified thickness, and then foamed in the foaming furnace, so that it has the softness that can adapt to the production of various products and different requirements, and the surface treatment is carried out at the same time as the furnace (dyeing, embossing, polishing, matting, grinding surface fluffing, etc., mainly in accordance with the specific product requirements).
PU leather is more complex than PVC leather in the manufacturing process, because the base fabric of PU is a canvas PU material with good tensile strength, in addition to being coated on the top of the base fabric, the base cloth can also be contained in the middle, so that the existence of the bottom cloth is not the same. The physical properties of PU leather are better than PVC leather, with bending resistance, good softness, high tensile strength, and air permeability (PVC none). The pattern of PVC leather is made by hot pressing of steel pattern rollers; The pattern of PU leather is to use a kind of pattern paper to heat press on the surface of semi-finished leather, wait for it to cool down, and then separate the paper leather for surface treatment.
The ** of PU leather is more than twice as high as that of PVC leather, and the ** of PU leather with some special requirements is 2-3 times higher than that of PVC leather. Generally, the patterned paper required for PU leather can only be scrapped after 4-5 times; The service life of the pattern roller is long, so the cost of PU leather is higher than that of PVC leather.
There are also certain differences in the scope of application of these two materials. In terms of footwear, PVC leather is mostly used in lining or non-weight-bearing parts, or in the manufacture of children's shoes; PU leather can be applied to the fabric of footwear or to the parts that bear weight. In terms of bags, PVC leather is more applicable.
This is because the items in the bag are different from the feet worn in shoes and do not emit heat; You don't have to bear your personal weight.
The difference between PU and PVC is relatively easy, and the base fabric of PU is much thicker than PVC from the corners, and there is also a difference in the feel, and the feel of PU is softer; PVC has a harder feel; It can also be burned with fire, and the taste of PU is much lighter than that of PVC.

Hanpi is actually cowhide leather made in Korea! There is nothing special, but in the past few years, South Korea has advanced technology, high quality, many new products and new processes, and a lot of investment in China. Moreover, the country has been importing Korean cowhide products, etc.!
