?.
Optimally, in step (a), the first island component, the second island component and sea in the figured sea-island staple fiber
The weight percent of ingredient is respectively 15%~45%, 15%~45%, 10%~40%.
Optimally, in step (b), the grammes per square metre of the non-woven fabrics is 50~350g/m2。
Optimally, in step (a), the marine origin is divided into alkali soluble polyester or polyolefin.
The invention has the beneficial effects that: present invention softness combined artificial leather, by macromolecular elastomer matrix
The two different polyester fibers of interior setting and on the tapetum on its surface equally distributed concave plane bulk resin, and gather
The parallel type polyester fiber that ester fiber material is selected from two kinds of differences, has inherent viscosity (IV) difference, can obtain mechanical property in this way
Artificial leather excellent, dimensionally stable is good can be used in upper leather, automotive interior material, furniture leather etc..
Specific embodiment
Softness combined artificial leather of the 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 and the blocky resin that is formed on the tapetum, the fibre blend be figured sea-island staple fiber island at
Point, it includes two kinds of differences and with the parallel type polyester fiber of inherent viscosity difference.Good mechanical performance, ruler can be obtained in this way
The good artificial leather of very little stabilization 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 material of the polyester fiber
Matter is high intrinsic viscosity poly dimethyl terephthalate (DMT) and is selected from low intrinsic viscosity poly dimethyl terephthalate (DMT), and characteristic is viscous
Degree difference is 0.1dL/g~1.5dL/g (i.e. polyester of the fibre blend comprising high intrinsic viscosity poly dimethyl terephthalate (DMT) material
The polyester fiber of fiber and low intrinsic viscosity poly dimethyl terephthalate (DMT)), when inherent viscosity difference is lower than 0.1dL/g, compound fibre
It ties up in forming process, it is big by structural differences bring 3 D stereo crimp radius, 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~6 μm.The macromolecular elastomer matrix is polyurethane.The polyester fiber is average diameter 0.1
μm~10.0 μm of 3 D stereo coiled structure.The bulk resin is concave plane bulk resin, is selected from polyethylene
With the combination of one or both of polycarbonate, distribution content is 5~100g/m2.The macromolecular elastomer matrix is poly-
Urethane.
The preparation method of above-mentioned softness 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, then processes to form compound nonwoven cloth through needing machine obvolvent；(c) non-woven fabrics is carried out high
Molecular flexibility body pads, de- extra large 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 are respectively by each self-spray
The path of wire hole is converged in spinneret outlet with sea component, forms island structure arranged side by side) formation is sprayed, therefore its island phase is (i.e.
First island component, the second island component) and marine facies (i.e. sea component) in the length direction of fiber be continuous, equally distributed；Island number
It 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
Dissolubility polyester (COPET).The weight of first island component, the second island component and sea component in the figured sea-island staple fiber
Percentage is respectively 15%~45%, 15%~45%, 10%~40%；When sea component content is higher than 40%, marine origin will cause
Point dissolution is difficult, while also sea component usage amount can be made excessive, in rear road manufacturing procedure caused by dissolve out the polymer of part
More, environmental pollution is heavier；When second island component composition by weight percent is higher than 35%, the arranged side by side multiple of composite fibre will cause
Conjunction rate is high, and cracky wears no resistance.In step (b), the grammes per square metre of the non-woven fabrics is 50~350g/m2.Dry type makes mask body
Are as follows: it is sprayed in the release paper of painting polyethylene and polycarbonate (polyethylene: poly- carbonic acid=50:50, mass ratio) hybrid resin
Binder (binder be commercially available polyurethanes, such as PU-7510 model), then the artificial skin's base fabric of fitting processing in formation
On tapetum, heated solidification.
