Abstract
The invention provides a manufacturing method for non-figured island-in-sea superfine fiber artificial leather which feels soft and smooth and extremely resembles real leather. The method is characterized by comprising the following steps: spinning HDPE and nylon together to obtain fiber with certain fineness by using the method of melt spinning; preparing a non-woven fabric from the fiber by using the method of needle-punching; allowing the non-woven fabric to be impregnated with polyurethane resin; solidifying and drying an obtained mixture; allowing the mixture to enter into a toluene extraction groove which contains a co-solvent of toluene and diethylene glycol or a co-solvent of toluene, diethylene glycol and oleamide; taking the mixture out from the toluene extraction groove so as to obtain superfine fiber; and softening the superfine fiber by using a machine so as to obtain the superfine fiber artificial leather. The co-solvent of toluene and diethylene glycol comprises, by weight, 50 to 95 parts of toluene and 5 to 50 parts of diethylene glycol; and the co-solvent of toluene, diethylene glycol and oleamide comprises, by weight, 50 to 95 parts of toluene, 5 to 50 parts of diethylene glycol and 5 to 50 parts of oleamide.
Description
Technical field
The invention belongs to superfine fibre artificial leather preparation method field, soft smooth, the not island ultrafine fiber artificial leather preparation method that kishke feel is strong of especially a kind of ultra fine artificial leather.
Background technology
The island ultrafine fiber artificial leather is not a skin emulation effect best fabricate-leather, and its intensity, durability and feel aspect are all similar with corium.At present superfine fibre artificial leather manufacture craft is: adopt melt spinning method that HDPE and nylon are spun into the fiber of certain fineness jointly earlier, adopt needle point method to make nonwoven fabric then, with nonwoven fabric impregnation polyurethane resin; Solidify; Oven dry gets into TOL and extracts groove out, and heated TOL is with HDPE composition dissolving in the fiber; Then the fineness of fiber further reduces in the leather; Obtain superfine fibre, machinery is done and is obtained soft ultra fine artificial leather base after soft, and the back is carried out the dry method surfacing process again and just can be obtained ultra fine artificial leather finished product.Because the restriction of spining technology at present, nylon fiber also can't reach enough fineness, so feel aspect pliability is strong not enough, still is restricted in its use of some special dimension.
Summary of the invention
The purpose of this invention is to provide soft smooth, the not island ultrafine fiber artificial leather preparation method that kishke feel is strong of a kind of ultra fine artificial leather.
Technical scheme of the present invention is: a kind of not island ultrafine fiber artificial leather preparation method, and it is characterized in that comprising the following steps: adopting melt spinning method that HDPE and nylon are spun into the fiber of certain fineness jointly, adopt needle point method to make nonwoven fabric then; With nonwoven fabric impregnation polyurethane resin, solidify, dry, get into toluene and extract groove out; Said toluene is extracted out in the groove and is contained the cosolvent of toluene and diethylene glycol or the cosolvent of toluene and diethylene glycol and oleamide; After toluene extraction groove, the HDPE composition is dissolved fully in the fiber, and the nylon composition is by slight corrosion; Extent of corrosion is by the concentration control of diethylene glycol; Then the fineness of fiber further reduces in the leather, obtains superfine fibre, and machinery is done and obtained soft ultra fine artificial leather after soft.
Weight ratio part is in said toluene and the diethylene glycol cosolvent: 50～95 parts of toluene, 5～50 parts of diethylene glycols.
Weight ratio part is in the cosolvent of said toluene and diethylene glycol and oleamide: 50～95 parts of toluene, 5～50 parts of diethylene glycols, 5～50 parts of oleamides.
Effect of the present invention is: island ultrafine fiber artificial leather preparation method not; Toluene is extracted out in the groove and is contained the cosolvent of toluene and diethylene glycol or the cosolvent of toluene and diethylene glycol and oleamide; A nylon composition dissolving part in the ultra fibre, thereby make superfine fibre thinner, the ultra fine artificial leather that obtains is soft and smooth; Kishke feel is strong, and added value is high.
Below in conjunction with not limiting embodiment the present invention is done further explanation.
