Abstract
The invention relates to a production method of suede superfine fiber synthetic leather. The production method of the suede superfine fiber synthetic leather includes: introducing a dry-method coating technology; coating high-solid-content suede resin coating on a superfine fiber non-woven fabric surface layer; forming compact and uniform resin bubble holes in the non-woven fabric surface layer by permeation, drying and solvent evaporation; then implementing impregnation, reduction and afterfinish technologies to finally form the suede superfine fiber synthetic leather which is compact in surface, uniform, and relatively low in production cost.
Description
Technical field
The present invention relates to technical field of synthetic leather, a kind of suede superfine fiber synthetic leather
Production method.
Background technology
Suede superfine fiber synthetic leather is that surface has natural suede floss effect, substitutes natural suede
It is widely used in for footwear, case and bag, the artificial leather of clothing.
Traditional suede superfine fiber synthetic leather produces, and matte resin is mainly impregnated with by wet method
Mode enters superfine fibre nonwoven cloth, then by wet coagulation, in displacement wet method impregnation material
DMF, forms abscess, then the sea component in decrement operation dissolves superfine fibre, and it is fixed to dry
Type, by mill skin and the combination of dyeing and finishing technology, forms surface and has the synthetic leather of suede nap effect.
The pile effects of suede nap depends primarily on the density of wet method resin abscess, fineness, uniformity,
Fineness with fiber.
Due to wet method impregnation, solidification the abscess that formed of mode by resin stability, auxiliary agent,
The impact of curing condition, and the restriction of solid content, the abscess forming dense uniform has certain tired
Difficulty, simultaneously because special matte resin price is significantly higher than ordinary resin, also results in whole product
Product are relatively costly.
Summary of the invention
The technical problem to be solved be solve conventional suede leather cell uniformity not,
The problem fine and close not, production cost is high, it is provided that one shows densification, uniform, production cost
The production method of relatively low suede superfine fiber synthetic leather.
For solving above-mentioned technical problem, this production method introduces dry coating technique, first by Gao Gu
The matte resinous coat of content is coated on superfine fibre nonwoven cloth surface layer, by permeating and being dried,
Volatilized by solvent again, form densification, uniform resin abscess at non-woven fabrics surface layer, then implement
Impregnation, decrement, postfinishing process, ultimately form show densification, uniformly, production cost relatively low
Suede superfine fiber synthetic leather.
The production method of a kind of suede superfine fiber synthetic leather of the present invention includes walking as follows
Rapid:
1, island superfine fiber processing: first sea component is cut into slices (such as polyethylene, water solublity
Polyester, water-soluble cellulose and polypropylene etc. cut into slices) and island component slices (as polyamide cut into slices,
Polyester slice) two kinds of raw materials make island superfine fiber by spinning production process；Spinning produces
Operation includes being spun or spinning by the way of Compound spinning by mixed melting, and nascent strand is special
Air-conditioning ring blowing under the conditions of cooling forming；In order to optimize spinning property and the physical property of strand
Can, strand is oiled, and it is poly-to utilize the drawing-off effect of draw roll to improve the height within strand
The trend concordance of thing molecule, now strand internal structure basically reaches requirement；Then by folded
Silk machine, crimping machine also oil once again, carry out piddler, through relaxation heat setting in course of conveying
After the effect of machine, the face shaping of the internal structure of strand, physical property and strand just reaches
Production requirement also settles out；Last strand is again through silk guide frame, traction tensioner and cutting machine
With the length set, strand being cut off, finished silk enters baling press by air delivery pipe and completes bag
Dress；
2, non-weaving cloth produces: utilize bale opener that island superfine fiber is put into loosening mixer
Carry out shredding mixing, and add specific oil preparation (palm oil grease, emulsifying agent, antistatic additive) and enter
The optimization of the spinnabilitys such as row such as antistatic, carries out fiber combing subsequently into carding machine, combing
After fiber enter high-precision lapping machine by feeding unit and be laid to net, thickness and density are high
Spend uniform fibre web with constant speed by needing machine or spun-laced machine, at pricker or the work of liquid drugs injection
With entangled to each other armful of lower fibre web internal fiber and, form the non-woven of structure and stable physical property
Cloth；Non-weaving cloth passes through thermal finalization fixed thickness and shape, is finally made sizing non-weaving cloth；
3, matte polyurethane coating: by matte resin and a certain proportion of solvent of high solids content
Mixing, and coat sizing nonwoven fabric surface, coating medium penetrates into sizing non-weaving cloth table
Layer, by oven for drying, during drying, solvent volatilization, forms fine and closely woven hole-layer foam, and
Solidification prepares semi-finished product after coating；
4, paint rear semi-finished product impregnation to process: first polyurethane resin is diluted to certain viscosity
And inject impregnating groove；Then will paint rear semi-finished product to carry out closing padding liquid by impregnating groove；Finally
Base fabric containing slurry is implemented curing process, and solidification is replaced by solvent or is dried or salt solidification
Hardening of resin is made, by making semi-finished product after impregnation containing soaking technology etc. mode；
5, island superfine fiber Alkali reduction method dissolves sea component: is sent into by semi-finished product after impregnation and subtracts
Measuring tank, groove is built with solvent or aqueous slkali, under the effect of solvent or aqueous slkali, to sea component
Dissolve, after multiple-grooved is dissolved, be carried out with boiling water, it is achieved the fibrillation of superfine fibre
Prepare fibrillation semi-finished product；
6, the finished product manufacture of suede superfine fiber synthetic leather: fibrillation semi-finished product carry out drying and shaping,
The most again by mill skin and the combination of dyeing and finishing technology, form the colored surface with even compact
Suede nap effect, is finally made suede superfine fiber synthetic leather finished product.
The positive effect of the present invention:
The production method of a kind of suede superfine fiber synthetic leather of the present invention, by by large arch dam
The matte resin mixture coating of amount is with dry, at super fine non-woven fabrics by the way of solvent volatilizees
Top layer forms uniform fine and close hole-layer foam, then implements impregnation, decrement, postfinishing process,
Make surface eventually and there is densification, uniform velvet effect, the matte superfine fibre that production cost is low
Synthetic leather.
Owing to the process control degree of solvent volatilization is high, the abscess of formation is finer and closely woven, is impregnated with tree simultaneously
Fat uses ordinary resin, so final product not only has careful careful pile effects, with
Time processing procedure stable, production cost is low.
