Description
The present invention relates to a kind of preparation of resin specially for dyable fine denier polypropylene fibre, belong to weaving
Technical field.
Polypropylene fibre is low because of its cost, function admirable, of many uses, is subject to people's attention day by day.The restriction polypropylene fibre is used and the principal element of development has: be difficult to thin dawnization and be difficult to dyeing.Under whole world fiber scientific worker's joint efforts, the thin dawn problem of polypropylene fibre is resolved finally.Polypropylene macromolecular structure height stereoregular, polar functionalities not again, thereby be difficult to dye, dye on the polypropylene fibre after the thin dawnization is more difficult.The vapour Jia Ji company of clinging to has proposed a kind ofly to obtain organic dyestuff by anthraquinone and a kind of silane reaction.It is said that this dyestuff has Color preferably, the dyefastness height to unmodified and nickel modified polypropene.But it is still limited to dye polyacrylic dye species on direct so far.Another approach that the solution polypropylene surface can be dyed problem is the dyeable modified polypropylene of development, and main method of modifying has: surface modification (light, radiation, agent treated) and body modification (modification by copolymerization, blending and modifying).Surface modifying method is because the defective of economy, the feature of environmental protection and color quality, at present large-scale application not as yet.The modification by copolymerization method is owing to the specific (special) requirements of polypropylene to polymerization catalyst, and the adding of polymer monomers often causes catalyst poisoning, and therefore, this technology does not have industrialized prospect so far as yet.Blending modification method is a most convenient in all method of modifying, economic method.
The purpose of this invention is to provide a kind of preparation of resin specially for dyable fine denier polypropylene fibre, have the disperse dye dyeable performance with the resin dedicated fine count fiber of making for preparing.
This purpose is by realizing by the following technical solutions: a kind of preparation of resin specially for dyable fine denier polypropylene fibre is characterized in that operating procedure:
First step raw material is prepared, take by weighing 77～98%wt polypropylene material, 2～20%wt TPO and 0～3%wt TPO derivative successively respectively as preparation resin dedicated matrix, blend additive and the 3rd component additive, polypropylene material is for spinning the polypropylene material of fine count fiber, and the melt index of blend additive is 3～100;
Second goes on foot blending and modifying and makes finished product, matrix, blend additive and the 3rd component additive are carried out binary or the modification of ternary melt blending, melt temperature is 200～280 ℃, makes the dyeable modified acrylic resin of finished product, i.e. resin specially for dyable fine denier polypropylene fibre.
But blend additive polyethylene or polystyrene, but the 3rd component additive maleic anhydride and polypropylene graft polymer or acrylic acid and polypropylene graft polymer or acrylic acid-grafted polystyrene, the graft polymers percent grafting is 0.3～3%wt.
Blend additive and the 3rd component additive add polypropylene-base, the latter's height ordered structure is broken up, this point can be confirmed by density reduction and degree of crystallinity reduction, provide " passage " for dying diffusion on the DISPERSE DYES molecule, polarity gene in the additive provides the necessary seat that dyes for dye molecule, improved dyefastness, the 3rd component additive has also further improved the compatibility of additive and polypropylene-base simultaneously, helps spinning fine count fiber.
It is resin dedicated that above-mentioned preparation method makes, through melt spinning: fusion, spray silk, stretch, reel, can make the dyable fine denier polypropylene fibre that fibre single thread fiber number, fibrous fracture intensity and fibrous fracture elongation were respectively for 0.5～1.8 dawn, are not less than 2.5CN/dtex and 15～80%.The physical and mechanical properties index of above-mentioned dyable fine denier polypropylene fibre meets the requirement of weaving back processing, can successfully on knitting and weaving equipment, weave the dyable fine denier polypropylene fibre fabric, available common dyeing dyes, as dark partially in dying with DISPERSE DYES, washing fastness reaches 4～5 grades, and soaping fastness reaches about 4 grades.
Compare with background technology, the present invention has following advantage:
1. the present invention adopts the blending and modifying technology to realize the thin dawnization of polypropylene fibre and organic unity that can dying, not only economy but also practicality.
2. the resin dedicated fine count fiber of making for preparing with the present invention can dye with common dyeing, and cost is low, and is effective.
