Park Ji Hyung Manufacturing Method of Artificial Leather

摘要

The present invention is a staple fiber by mixing and spinning 30 to 50% by weight polyethylene resin and 50 to 70% by weight of nylon or polyester resin in the melt index 40 to 80g / 10min range by weight 500 to 700g / ㎥, thickness through needle punching After preparing a nonwoven fabric with a punch density of 1.8 to 2.2 mm and a punching density of 2,500 times / cm 3 or more, it was impregnated into a polyurethane elastomer solution containing an additive having affinity with a dye, and then divided into two or three parts by a thickness for proper use. After immersing in tetrachloroethylene or toluene at 70 to 100 ° C for 10 to 20 minutes to remove the polyethylene component, the dye and the dyestuffs are mixed and mixed with an appropriate ratio and surface treated with sandpaper to have a fineness of 0.005 to 0.001 denier. Produces artificial leather that has similar volume, wet touch, and soft texture to natural leather. Will.
