Oil carries out piddler in transmission process, after the effect by loosening heat setting machine, the internal structure of strand, physical property and
The face shaping of strand just reaches production requirement and settles out；Last strand is using silk guide frame, traction tensioner and cut-out
Machine cuts off strand with the length set, and finished silk enters baling press by air delivery pipe and completes packaging；
2) non-woven cloth produces
Island superfine fiber is put into loosening mixer using bale opener and carries out shredding mixing, and the antistatic agent of addition 1% is matched
Liquid processed carries out the optimization of spinnability, carries out fiber combing subsequently into carding machine, the fiber after combing is entered by feeding unit
High-precision lapping machine is laid with networking, and the fibre web of thickness and density high uniformity passes through needing machine or spun lacing with constant speed
Machine, under the action of perverse needle or liquid drugs injection entangled to each other armful of fibre web internal fiber and, form structure and the non-of stable physical property knitted
Make cloth；Non-woven cloth is finally made sizing non-woven cloth by thermal finalization fixed thickness and shape；
3) wet impregnation technique
By polyurethane, graphene, solvent, auxiliary agent etc. is made into the slurry that solid content is 22%-24%, injects impregnating groove, will shape
Non-woven cloth carries out containing padding liquid by impregnating groove；Curing process finally is implemented to the base fabric containing slurry, is replaced by solvent
Or the modes such as drying or salt solidification make hardening of resin, and semi-finished product after impregnation are made；
4) island superfine fiber Alkali reduction method dissolves sea component
Semi-finished product carry out fibrillation by hot benzene Subtraction method after being impregnated with, and the property of this hot solvent can be dissolved in using sea component, pass through
Multistage dissolving repeatedly extrudes removal sea component, finally washes bass with hot water, removes remaining solvent, and fibrillation semi-finished product are made；
5) final finishing of half product of superfine fiber chemical leather and finished product manufacture
Fibrillation semi-finished product are dried and the drying and shaping that oils；Then through grinding skin, the finishing process such as skin is rubbed and obtain superfine fibre
Half product of synthetic leather；Manufactured half product bass can be produced into good superfine fibre by techniques such as dyeing, veneer, surface treatments
Synthetic leather products.
