Specific embodiment
The wear-resisting combined artificial leather of the present invention, it includes macromolecular elastomer matrix, is set to the macromolecular elastomer
The intracorporal fibre blend of base, the villus for being formed in the macromolecular elastomer matrix surface and being made of the fibre blend
Layer, the bulk being formed in the tapetum melt a little and are distributed in the blocky resin on the tapetum, and the fiber is mixed
The island component that object is figured sea-island staple fiber is closed, it includes two kinds of differences and with the parallel type polyester of inherent viscosity difference
Fiber.Block is set in the tapetum on its surface and two different polyester fibers are set in macromolecular elastomer matrix
Shape melts the concave plane bulk resin being evenly distributed a little and on tapetum, and polyester fiber material be selected from two kinds of differences and
There is the polyester fiber of inherent viscosity (IV) difference, good wearability, glossy, dimensionally stable, good color fastness, mechanics can be obtained in this way
The artificial leather of function admirable can be used in upper leather, automotive interior material, furniture leather etc..
The polyester fiber is three-dimensional crimp structure, and crimp radius is 0.01mm~0.2mm.The bulk resin is choosing
From the combination of one or both of polyethylene and polycarbonate, distribution content is 5~100g/m2.The polyester fiber
Material is that high intrinsic viscosity poly dimethyl terephthalate (DMT) and low intrinsic viscosity poly dimethyl terephthalate (DMT), inherent viscosity are poor
For 0.1dL/g~1.5dL/g (i.e. polyester fiber of the fibre blend comprising high intrinsic viscosity poly dimethyl terephthalate (DMT) material
With the polyester fiber of low intrinsic viscosity poly dimethyl terephthalate (DMT)), inherent viscosity difference be lower than 0.1dL/g when, composite fibre at
It is big by structural differences bring 3 D stereo crimp radius during type, required result is not achieved；Inherent viscosity difference is higher than
When 1.5dL/g, since the structural differences between polymer are excessive, easily occur fracture of wire, difficulty in spinning on spinneret.The polyester
The diameter of fiber is 0.1 μm~10 μm (preferably 0.1 μm~6 μm).The macromolecular elastomer matrix is polyurethane.
The preparation method of above-mentioned wear-resisting combined artificial leather, it is the following steps are included: (a) passes through three component spinning equipment systems
Standby figured sea-island staple fiber；The figured sea-island staple fiber includes sea component, the first island component and the second island
Ingredient, the first island component and the second island component form parallel construction, and marine origin is divided into dissolution type polymer；(b) by the figured type
Island composite short fiber combs lapping after mixing with low-melting fiber, then processes to form compound nonwoven cloth through needing machine obvolvent；Institute
Stating low-melting fiber is polyester, modified poly ester, polypropylene, nylon or polyethylene, and the mass content in compound nonwoven cloth is
0.1~1.0% and fusing point be 120 DEG C~230 DEG C；(c) to the non-woven fabrics carry out macromolecular elastomer pad, de- sea processing,
Sanding, dyeing, arrangement and dry type make face.
In step (a), figured sea-island staple fiber is to lead to the first island component, the second island component and sea component respectively
Cross three component composite spinning machines melting, into fabric of island-in-sea type filament spinning component, (the first island component, the second island component pass through respective respectively
After path is converged in the outlet of spinneret orifice and to form skin-core structure, then export and converge in spinneret with sea component) formation is sprayed, therefore
Its island phase (i.e. the first island component, the second island component) and marine facies (i.e. sea component) are continuous, uniformly point in the length direction of fiber
Cloth；Island number is fixed, generally on 8 islands or more.Sea component is usually alkali soluble polyester or the easy dissolution type polymer of polyolefins,
Preferably alkali soluble polyester (COPET).First island component, the second island component and marine origin in the figured sea-island staple fiber
The weight percent divided is respectively 15%~45%, 15%~45%, 10%~40%；When sea component content is higher than 40%, meeting
Cause sea component dissolution difficult, while also sea component usage amount can be made excessive, in rear road manufacturing procedure caused by dissolve out part
Polymer it is more, environmental pollution is heavier；When second island component composition by weight percent is higher than 35%, composite fibre will cause
Recombination rate arranged side by side it is high, cracky wears no resistance.In step (b), the grammes per square metre of the non-woven fabrics is 50~350g/m2.Dry type is made
Mask body are as follows: in the release paper of painting polyethylene and polycarbonate (polyethylene: poly- carbonic acid=50:50, mass ratio) hybrid resin
On spray binder (binder be commercially available polyurethanes, such as PU-7510 model), then artificial skin of the fitting processing in formation
On the tapetum of base fabric, heated solidification.
The preferred embodiment of the invention will be described in detail below:
