好奇忍不住google了一下 “genuine leather”
The following are not "true" organic leathers, but are materials that contain leather fiber. Depending on jurisdiction, they may still be labeled as "Genuine Leather", even though the consumer generally can only see the outer layer of the material and can't actually see any of the leather content:
Bonded leather or reconstituted leather is an economical material that uses leftover organic leather (from tanneries or workshops) that are shredded and bonded together with polyurethane or latex on to a fiber sheet. The varying degree of organic leather in the mix (10% to 90%) affects the smell and texture. Its reduced cost makes it popular for furniture upholstery, especially for commercial furniture that requires durability—though durability can vary widely depending on the formulation.
Bycast leather is a split leather with a layer of polyurethane laminated to the surface and then embossed. Bycast was originally made for the shoe industry, and later adopted by the furniture industry. The original formula created by Bayer was strong but expensive. The result is a material that is slightly stiffer but cheaper than top-grain leather but has a much more consistent texture. Because its surface is completely covered in plastic, is easier to clean and maintain, but is not easily repaired.
Usually on the underside of a belt or inside a leather good, the leather quality will be stamped one of three things: genuine leather, top-grain leather, or full-grain leather.
But what exactly do these mean? When you’re buying your fancy leather briefcase, jacket, or shoes, you should know exactly what to look for in your leather.
Genuine leather doesn’t just mean that the product is made of real leather (which it is), but it also means it is the lowest quality of all products made out of real leather.
Genuine leather generally doesn’t last as long or look as nice as higher-quality leather. You’ll typically find it in belts from mall stores, shoes from lower-priced department stores, and bags or other goods in the lower-leather price range.
Goods marked as genuine leather will be several layers of low quality leather bonded together with glue and then painted to look like a better-quality leather. It’s what is left over when the other, higher grades are stripped away.
This grade of leather is acceptable if you’re just buying something cheaply and don’t care too much about its quality. It won’t last very long, so it probably shouldn’t be something you use every day. |
