Abstract:
1. A method of manufacturing a microfiber artificial leather, the method comprising: selecting microfiber as pile warp, and yarn as ground warp and ground weft, wherein the pile warp adopts V-shaped or W-shaped consolidation, uses the double warp-pile weaving technology to weave into double-layer pile fabric on pile weavers, and uses pile cutters to cut the pile warp thread joining the two layers of ground fabric so that the double-layer pile fabric is halved into single-layer pile fabric respectively with ground warp, ground weft and V-shaped or W-shaped pile warp to form a hair surface, featuring a three-dimensional structure; immersing the pile fabric in a polyurethane finishing liquid, padding the pile fabric, then treating the pile fabric in a coagulating liquid; washing and drying the pile fabric so that the polyurethane in the pile fabric forms a continuous microporous membrane; after drying, applying an alkali treatment to the microporous membrane pile fabric comprising polyurethane so that the pile warp is fully dispersed into single fibers to form microfibers, and then fully washing the microfibers in water to remove alkali liquid remaining from the alkali treatment, as well as alkali-soluble monomers and oligomers; carrying out sanding, dyeing and finishing operations to obtain microfiber artificial leather.
