Výzva syntetickej kože k prírodnej koži
Prírodná koža je vďaka svojim vynikajúcim prírodným vlastnostiam široko používaná pri výrobe predmetov dennej potreby a priemyselných výrobkov. Avšak, s rastom svetovej populácie, ľudský dopyt po koži sa zdvojnásobil, a obmedzené množstvo prírodnej kože už dlho nie je schopné uspokojiť tento dopyt. Aby sme tento rozpor vyriešili, scientists began to research and develop artificial leather and synthetic leather decades ago to make up for the shortcomings of natural leather. The historical process of more than 50 years of research is the process of artificial leather and synthetic leather challenging natural leather.
Scientists began by studying and analyzing the chemical composition and structure of natural leather, starting with nitrocellulose varnished cloth, and entering PVC artificial leather, which is the first generation of artificial leather. On this basis, scientists have made many improvements and explorations, first the improvement of the substrate, and then the modification and improvement of the coating resin. In the 1970s, the synthetic fiber non-woven fabrics were needle punched into nets, bonded into nets, atď., so that the base material had a lotus-shaped section, hollow fiber shape, and reached a porous structure, which was in line with the network structure of natural leather. Requirement; At that time, the surface layer of synthetic leather can be made into a microporous structure polyurethane layer, which is equivalent to the grain surface of natural leather, so that the appearance and internal structure of PU synthetic leather are gradually close to natural leather, and other physical properties are close to those of natural leather. Index, and the color is more vivid than natural leather; its normal temperature folding resistance can reach more than 1 million times, and low temperature folding resistance can reach the level of natural leather. Vznik mikrovláknovej PU syntetickej kože je treťou generáciou umelej kože. Netkaná textília so sieťou trojrozmernej štruktúry vytvára podmienky na to, aby syntetická koža dobiehala prírodnú kožu z hľadiska základného materiálu.. Tento produkt kombinuje novo vyvinutú impregnáciu PU kašou a technológiu spracovania kompozitnej povrchovej vrstvy s otvorenou štruktúrou pórov, má obrovský povrch superjemných vlákien a silnú absorpciu vody, vytvorenie superjemnej PU syntetickej kože má zväzok superjemnej Inherentné hygroskopické vlastnosti prírodnej kože vyrobenej z kolagénových vlákien sú z hľadiska vnútornej mikroštruktúry porovnateľné s vysokokvalitnou prírodnou kožou, vzhľad, textúra, fyzikálne vlastnosti, a pohodlie pri nosení. Navyše, microfiber synthetic leather surpasses natural leather in terms of chemical resistance, quality uniformity, large-scale production and processing adaptability, and waterproof and mildew resistance.
Practice has proved that the excellent properties of synthetic leather cannot be replaced by natural leather. From the analysis of domestic and foreign markets, synthetic leather has largely replaced natural leather with insufficient resources. The use of artificial leather and synthetic leather for the decoration of bags, odevy, topánky, vehicles and furniture has been increasingly recognized by the market. Jeho široká škála aplikácií, veľké množstvá, a mnohé odrody nemôžu byť uspokojené tradičnou prírodnou kožou.
