Synthetic Fibre Suede Fabric Production Process II
1. Weaving process
Before weaving to do twisting or coated evenly, finalize the design when the vacuum degree and higher, choice of cooling process is very important, otherwise the fabric after dyed color flower is seen.
2．Sanding, dyeing and sueding
Grinding effect is bad, fur would have produced deep and light color.Fabric mill fur is done by cutting emery, burning on mesh is small, silicon carbide particles, grinding suede fabric for fabric force is big, in the process of grinding out the hair long, fabric strength decline also big, on the contrary, if the burning on mesh is too big, suede fabric was more difficult, also raised the cost accordingly. We according to the grinding mechanism of fur, the five sand roller adopted a "first light" after the grinding process, fur is the first choose low sand roller mesh burning on tape.Purpose is as much as possible to pull the fiber in yarn cut into single fiber; After four sand roller chose burning on the number of relatively high mesh belt, the purpose is to continue to pull the fiber in yarn cutting, and more importantly will pull cutting single fiber grinding into fluff, in this way can make the grinding after the nap better to achieve the effect of "thin short dense well". The tension is also very important when dyeing, tension is too large will produce wool phenomenon, such as chicken claw shape defects.
Because of suede velvet adopt is to dissolve the sea island silk fiber, fabric after soluble fiber mill wool fiber processing, fibre separated form superfine fibre, with a strong effect of suede, is more popular at home and abroad market of high-grade fabric, has a broad market and good returns.
