Different materials under various leather goods

For leather manufacturers, many leather goods made of different leather materials have different leather surfaces, so for leather manufacturers, leather knowledge needs to be understood more. Pu material is mainly made by pouring a layer of polyurethane slurry on the surface of the bottom gauze and drying it; Because the surface layer is relatively thin, the bottom layer is also relatively thick. PVC material is PVC compound on the surface, and the base is knitted fabric, which is bonded with a layer of PVC resin film. The leather is thicker, the surface layer is thicker, the bottom yarn layer is also relatively thin and has yarn holes. PU / PVC composite artificial leather can be called semi Pu artificial leather, because this product has the characteristics of PU and PVC artificial leather. Because it is similar to natural leather, it is relatively widely used. In terms of characteristics, it is mainly cold resistant, heat resistant and torture resistant, more uniform in quality, higher tear strength and tensile strength, and higher resistance to solvents.
How to better choose leather clothes? In terms of light leather clothing, light leather clothing is mostly sheepskin, and also has pig skin and cow leather. There should be obvious color difference, no obvious defect points and aurora on the leather surface, and there is no special flatness and straightness, and pores can not be observed, because the pores are too thick, which belongs to the counter skin. When touching, it will better reflect the characteristics of leather clothing. Moreover, the good hand feel is that it feels more elastic, plump, fleshy and foaming. After pulling out, we will feel slightly smooth, and we can’t have some squeaky resin sound. When the fingers go up, the leather will be polished, and the pores will be clearer after the top. If it’s not smooth enough, and it doesn’t rebound enough, if it’s deep in wrinkle folding, If we haven’t removed it for a long time, it means it won’t be good leather, and it’s a relatively poor leather coat when it’s sticky and hard.
In terms of fur clothing, fur coats mainly come from the skins of two kinds of animals, one is mink, the other is fox. Whether the fur is glossy, whether the color is full and pure enough and more natural, and whether there is complete and abundant needle and wool in the fur quilt, and whether there is the phenomenon of bald needle and less wool. Whether there is inverted smooth hair and flexibility, rather than replacing more rough hair, hard hair and sticky hair. After observing all parts of our body, we can see whether the materials are reasonable, whether the colors follow and buckle with plush. Whether there is fullness, softness and light weight in touching leather board by hand. In terms of leather plate, the soft and light one is the top grade. The overall workmanship is to see whether it is fine enough, whether the stitches are uniform enough, and whether there is leakage.

In the daily maintenance of smooth leather, it is best to wear leather clothes often and wipe them with common fine flannel cloth. Remember to pay great attention not to wipe them with gasoline or water. Because water will harden the leather, gasoline will volatilize and dry crack the oil of the leather. Therefore, the main component of sheepskin, cowhide and pig skin is protein, which is very easy to peel, get damp and produce insects. Therefore, when wearing this kind of leather clothes, we should avoid contacting acidic, oily and alkaline substances as much as possible. Leather clothing should pay more attention to moisture-proof. If it is wet by rain, it should immediately use a dry towel to absorb moisture, and then place it in a cool place for air drying. What we should pay attention to is that leather clothes should be crack proof and fold proof, and should not be exposed to the sun, but also prevent baking. If there is a small crack on the leather surface, we can use a brush dipped in some egg white to smear it on the crack, and then apply duck oil or chicken oil for polishing. When we don’t wear it, we should remember to hang the clothes hanger, and don’t store and fold it, so as not to wrinkle and deflate it. When it affects the beauty, we’d better wear fine flannelette leather clothes for many times, and remember not to wipe it with water or gasoline, although water can have the ability to harden the water.
