Abstract
The invention relates to a method for preparing regenerated return polypropylene fibrilled film fibers, which comprises the following steps of extruding return polypropylene, carrying out film splitting on the return polypropylene, slitting the return polypropylene into filaments, coating an oiling agent on the filaments, carrying out steam preheating, curing, drying, cutting and packaging, or comprises the following steps of carrying out film splitting on the return polypropylene, slitting the return polypropylene into filaments, opening, carrying out short-cutting and packaging. In the invention, a fibrilled film filament process is used to carry out spinning, polypropylene regenerated return materials are sufficiently utilized, the production cost of the polypropylene fibers is reduced, and the method has a good application prospect.
Description
Technical field
The invention belongs to the preparation field of fibrilled film fibre, particularly a kind of preparation method of the feed back polypropylene fibrilled film fibre of regenerating.
Background technology
The kind of polypropylene fibre has long filament (comprising not modified continuous filament and varicosity modified continuous filament), staple fibre, bristlelike monofilament, film-fibre, doughnut, profiled filament, various composite fibre and bonded fabric etc.Main application is to make carpet (comprising carpet lining and matte), bunting, UPHOLSTERY FABRIC, various rope, band, fishing net, asphalt felt, building reinforcing material, packaging material and industrial cloth, like filter cloth, bagging etc.This external clothing aspect is used also extensive day by day, can process dissimilar BLENDED FABRIC with multiple fiber blend, can process shirt, coat, sweat shirt, socks etc. through after the knitting processing.By the wadding quilt that the polypropylene fibre doughnut is processed, light weight, warming, elasticity is good.Polypropylene spinning becomes polypropylene fibre; The general technology that all adopts melt spinning; And the technology of melt spinning all can not be utilized polypropylene regeneration feed back; Because polypropylene regeneration feed back tends to contain the multiple material beyond the polypropylene, like calcium carbonate, polyethylene, PVC etc., these materials can stop up the spinneret orifice of melt spinning.So can not find cheap feed back polypropylene short fiber on the market.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of the feed back polypropylene fibrilled film fibre of regenerating; This method adopts split yarn technology as before spinning; Make full use of polypropylene regeneration feed back, the production cost of polypropylene fibre is reduced, have a good application prospect.
The preparation method of a kind of feed back polypropylene fibrilled film fibre of regenerating of the present invention comprises:
(1) the polypropylene feed back is extruded through the polypropylene extruder after; Cool off film forming, utilize first drawing roller that film is pulled out from water-bath, then film is cut into polyacrylic fibres; The heating back is through second drawing roller; Utilize the speed difference of first drawing roller and second drawing roller, polyacrylic fibres is carried out hot drawing-off, oil to polyacrylic fibres then;
(2) the above-mentioned polyacrylic fibres that oils is passed through steam preheating, in the fiber crimp machine, polyacrylic fibres is curled, polyacrylic fibres oven dry and typing with curling good with the fibre cutting machine cut-out, promptly get the polypropylene fibrilled film fibre;
Or the above-mentioned polyacrylic fibres that oils used the opener shredding, and cut off with fibre cutting machine, promptly get the polypropylene fibrilled film fibre;
Or with the above-mentioned polyacrylic fibres that oils, cut off with fibre cutting machine, promptly get the polypropylene fibrilled film fibre.
Be cooled to water-bath cooling or air-cooled in the said step (1).
Heating means in the said step (1) are drying-plate heating or baking oven for heating method.
Oiling to polyacrylic fibres in the said step (1) oils through second drawing roller, oil bath or oiling roller.
Process route of the present invention is: the feed back polypropylene splits film → cut into silk → oil agent → steam preheating → curl → oven dry → cut-out → packing.According to the different application mode, also can use direct staple fibre.Directly the process route of staple fibre is: the feed back polypropylene splits film → cut into silk → shredding → weak point to cut → pack.
Beneficial effect
The present invention adopts split yarn technology as before spinning, and makes full use of polypropylene regeneration feed back, and the production cost of polypropylene fibre is reduced, and has a good application prospect.
