Description
Technical field
The present invention relates to a kind of production method washing hot melt composite monofilament, belong to chemical fibre technical field.
Background technology
Low-melting fiber the earliest, is the polyene hydrogen composite fibre succeeded in developing by Chisso Corporation (JP) 6-32, Nakanoshima 3-chome, Kitaku, Osaka, Japan of Japan.It is a kind of with PP as core, with PE as skin, in industrialization in 1997 years.Chisso Corporation (JP) 6-32, Nakanoshima 3-chome, Kitaku, Osaka, Japan is the pioneer in this field, and has almost monopolized the market of PP-PE and PET-PE fiber.Regrettably, the compatibility of PP and PE and PET, caking property are the most bad, so the application of this fibrid is restricted.In order to solve and the problem of polyester fiber bonding, UNITIKA company of Japan successfully develops Melty copolyester with low melting point product.Subsequently, abroad some esbablished corporations have also begun to the exploitation to other copolyesters series products.
Low-melting point polyester is a kind of random copolymerization modified poly ester with relatively low melting point, is a kind of raw material producing heat-bondable fibre, and fusing point is 150-170 degree, the most domestic relies primarily on import, for high-end clothing patch arm of angle lining and the adhesive tape of automotive trim.
Low-melting fiber, compared with polypropylene, Fypro, can occur flow deformation after the latter is melted, not resilient after cooling, thus heat-shrinkable is very big, and the contraction that low-melting fiber is in its free state is only 5%.Therefore, it can replace polypropylene, polyamide-based PUR in some fields, has the application that its own is unique simultaneously.This products material is easy to get, moderate cost, low cost, and preparation technology is simple, can industrialized production.Low-melting point polyester whether still suffers from wide purposes for fiber weaving aspect for adhesive, and its application is boundless, the most great market competitiveness and application prospect.
In terms of adhesive, mainly it is processed into adhesive tape process for clothing, the bonding etc. of automotive trim, being mainly used in textile yarn, industry weaving, health care, filtration filter material, technical fiber, geotextiles, non-woven fabrics, netting, insulation material in terms of fiber weaving, market income is good.
Prior art is primarily present following weak point: use single hot plate heat-shaping in the existing production UDY Si Hou road drawing-off course of processing, it is impossible to ensureing that the intensity of fiber and percentage elongation index are stable, product quality is not sufficiently stable.
Summary of the invention
