A kind of non-woven fibrous plate, be by multiple different staple fibre mix, through the needling process moulding and through the sheet material of heating process typing, it is characterized in that described mixing staple fibre is to be mixed by the polyester fiber of weight ratio 50%～60%, 20%～30% polyacrylonitrile fibre, 15%～25% polypropylene fibre to constitute.
A kind of manufacture method of non-woven fibrous plate, the short fiber material shredding that it is characterized in that to mix, make fiber web after dividing comb processing, fiber web is knitted through close acupuncture on needing machine, make base cloth with required thickness, base cloth is heated to the polypropylene fibre fusing, through hot pressing, making the base cloth surfacing and make the correction of base cloth thickness to product thickness then, just is the fibrous plate finished product after the typing to be cooled.
The fibre-bearing amount of above-mentioned fibrous plate is preferably every square metre of 500～1200 gram; The thickness of fibrous plate generally can be at 1.0～5.0 millimeters; Above-mentioned different staple fibre mixes can be even admixture, also can be non-homogeneous admixture, non-homogeneous admixture is just like keeping under the constant situation of the total occupancy volume of polypropylene fibre, low and the polypropylene fibre ratio height of fibrous plate internal layer of the polypropylene fibre ratio on fibrous plate top layer is in order to the softness characteristics that improves the fibrous plate top layer and tough elasticity of internal layer or the like; The pin density that above-mentioned close acupuncture is knitted can be on every square centimeter on 700～1300 pins; Heating-up temperature is preferably in 170 ℃～190 ℃, and preferably be no less than 1.5 minutes heat time heating time.
The mixing staple fibre of technique scheme adopts 50%～60% polyester fiber, 20%～30% polyacrylonitrile fibre, 15%～25% polypropylene fibre mixes formation, because the cohesive force that interweaves mutually of polyester fiber is quite strong and have a good stiffness, and in mixing staple fibre, occupy higher proportion, become the thickness of base cloth all can be thicker with acupuncture so can be made into fibroreticulate thickness, on needing machine, just can disposable processing generate all thickness that the end requires in the footwear like this, and superpose without multilayer, need not be through gum dipping process, so not only can make work simplification, and the production efficiency height; Owing to have enough toughness and stiffness,, help improving the ventilative and perspire of product so simultaneously so just can reduce as the polypropylene fibre content of hot melt adhesive material; Because polyacrylonitrile fibre has softness characteristics and wool characteristic, can make fibrous plate can not give the people hard cold sensation, product surface has the cortex feel, the product specification height, the while also can strengthen the toughness of product.Just because of distinctive materials of the present invention and proportioning, thereby making the preparation method of fibrous plate become quite simplifies, once just can sting the base cloth that weaves required thickness on needing machine, this production for the end in the various footwear with different-thickness requirement just seems convenient especially and makes product neat and artistic; Whole manufacturing process is not a bit all used the major-minor material of chemical resin adhesive as product, and is hundred-percent fibrous structure, so fibrous plate of the present invention is real free of contamination environment-friendly products, it has the advantage of the tasteless mildew-resistant concentrated base of anti-the peracid; The gas permeability of product and perspire are also good especially, and the same equal time humidity volatile quantity under the uniform temperature can reach 92%; Needing ben be that the folding Qu Xingneng of the fibrous plate that generated by manufacture method of the present invention is good especially, measures through machinery, and the bent number of times of folding can reach more than ten times of general like product.As seen fibrous plate of the present invention is the special-purpose material in the end in a kind of desirable footwear, its good operating characteristic be prior art can not compare.
