Description

A kind of polyphenylene sulfide superfine fiber/Synthetic Leather bass and preparation method thereof
Technical field
Prepared the present invention relates to polyphenylene sulfide superfine fiber base fabric and the combination process with polyurethane, be related specifically to one Plant polyphenylene sulfide superfine fiber/Synthetic Leather bass and preparation method thereof.
Background technology
Natural leather resource-constrained, the exploitation of the simulated composite leather with premium properties has turned into the pursuit of the mankind, although The synthetic leather yield of non-super-fine fiber material is very big, but still there is larger gap compared with corium.With constantly entering for technology Walk and perfect, superfine fiber chemical leather is attracted attention with its excellent combination property, and its production technology is also continued to develop.It is poly- The microstructure of urethane/superfine fiber chemical leather reference natural leather, with the non-woven fabrics with tridimensional network or island Fiber non-woven is base fabric, is prepared through wet method processing technology, extremely similar to natural leather in terms of outward appearance and immanent structure, The characteristics of flexibility, gas permeability and comfortableness with corium, and be better than in terms of physical property, chemical-resistance, the feature of environmental protection Natural leather, is the optimal substitute of natural leather.
Prior art, Chinese patent CN103015185A, in publication date on April 3rd, 2013, patent of invention is entitled " wear-resisting Superfine fibre suede and preparation method thereof ", Chinese patent CN105568709A, publication date on May 11st, 2016, patent of invention Entitled " a kind of preparation method of superfine fibre clothing leather ", Chinese patent CN103410009A, publication date November 27 in 2013 Day, patent of invention is entitled " vapor-permeable type superfine fiber polyurethane matte synthetic leather high, preparation technology and its product ", above patent Processing method be all, as raw material, composite fibre to be prepared by melt blending island method with polyester, nylon, polypropylene etc., then by Composite fibre is fabricated to leather base cloth, and its impregnation process is obtained ultra-fine after solidification, washing and fibrillation with polyurethane slurry then Fiber synthetic leather bass and finished product synthetic leather.The superfine fiber chemical leather prepared using above-mentioned patented method is soft, tool There are excellent gas permeability and the function such as crease-resistant.But, above inventive method is required for cutting off island-in-sea type composite fiber, combs Reason, lapping, consolidation process are made non-woven base fabric.After base fabric is processed through follow-up dipping, solidification, to carry out fibrillation treatment and carry out shape Into superfine fibre, this process will use substantial amounts of leaching solvent, cause whole preparation technology flow path efficiency low, preparation cost compared with Height, environmental pollution is serious.Further, since the raw material such as superfine fibre polyester, nylon, polypropylene for using belongs to combustible material, because This cannot prepare microfiber synthetic leather bass or finished product synthetic leather with ingrain fireproofing characteristic.
Polyphenylene sulfide (PPS) is a kind of new type functional material, because its molecular backbone is made up of phenyl ring and sulphur atom so that PPS has excellent anti-flammability (limited oxygen index 34~35) and chemical stability, and prepared PPS fibrous materials have higher Intensity and modulus and good dimensional stability.The PPS fibre diameters prepared using melt-spraying spinning are tiny, reach superfine fibre chi Very little level.Because the shaping of PPS superfine fibres is once completed, cumbersome fibrillation process is eliminated, therefore PPS superfine fibres are prepared into This is relatively cheap.While PPS resin is meltblown into fibre simultaneously, lapping can be directly completed on lace curtaining, prepare PPS superfine fibres Without fibrillation, carding step during base fabric, therefore, the technological process for manufacturing PPS melt-blown micro fibre base fabrics is relatively short, is prepared into This is low.Chinese patent CN104795525A, publication date on July 22nd, 2015, a kind of entitled " the melt-blown polyphenylene sulfide of patent of invention Non-woven fabrics lithium battery diaphragm and preparation method thereof ", and Chinese patent CN103961939A, publication date August in 2014 6 days, invention Patent name is " a kind of preparation method of polyphenylene sulfide composite filtering material ", is to dry polyphenylene sulfide pellet, through melting extrusion, cold But, coagulate net after, poly-p-phenylene sulfide ether superfine fibre net carry out hot rolling treatment and thermal finalization treatment, obtain polyphenylene sulfide superfine fiber without Spin cloth.Non-woven fabrics obtained by this method has the spies such as high intensity, high high-temp stability be good, air penetrability is high and chemical stability is good Point, can be used for preparing filtrate and lithium battery diaphragm.
Further, since polyphenylene sulfide superfine fiber has fabulous parent to the dimethylformamide or acetone soln of polyurethane And property, the dipping for being very beneficial for polyurethane slurry poly-p-phenylene sulfide ether superfine fiber fabric is combined, and the synthetic leather of preparation has excellent Good sanitation performance and mechanical performance.In view of the good anti-flammability of PPS superfine fibres, without adding extra flame retardant constituent, The synthetic leather prepared using PPS superfine fiber fabrics is by with certain ingrain fireproofing characteristic.
It can be seen that, in the prior art, with PPS not weaving fabric of superfine fiber as base fabric, impregnating polyurethane prepare gas permeability, Hygroscopicity and satisfactory mechanical property and synthetic leather bass and finished product synthetic leather with ingrain fireproofing, with preparation method letter Single, lower-cost advantage.
