Description

The manufacture method of dyable fine denier polypropylene fibre
The present invention relates to the manufacture method of polypropylene fibre, it is by adding the blend with it of other high polymer, so that the fiber of making has dyeability preferably in the polypropylene resin.
Polypropylene fibre is one of four big synthetic fiber, and its sufficient raw is cheap for manufacturing cost, and fiber then has plurality of advantages such as light specific gravity, warmth retention property are good, intensity height.Particularly in recent years with the appearance of fine denier polypropylene fibers, polypropylene fibre has also had very big development in the application facet of taking textile material.But because polar functionalities not in the big molecule of polypropylene adds that the stereochemical structure of its isotactic makes that big molecule regularity is very high, so that the fibre structure of making is tight, and dyeability is very poor.Usually people adopt Masterbatch to carry out original liquid coloring spinning colored fibre, but it has the diversity of high dyeing flexibility and color not as fiber or fabric printing after all.So improve the dyeability of polypropylene fibre is very active subject of this field always, and has obtained certain achievement so far.As patent US4,520,155, US4,764,551, CN90105404.6, CN92108576.1 and CN93114967.3 etc. have all proposed a kind ofly to carry out melt spinning after will having the additive of accepting the dyestuff ability and the blend of polypropylene resin, the fiber that makes has good dyeability, makes general dyeing method also can be applied to polypropylene fibre or fabric.But all there are some shortcomings more or less in these existent method, or rate of dyeing is not high enough, maybe can't spin fine count fiber, or the too low no industrial value of spinning silk winding speed.
The manufacture method that the purpose of this invention is to provide a kind of dyeable polypropylene fibre, it can be with higher spinning speed spinning fine denier dyeable polypropylene fibre.
The present invention also adopts after polypropylene resin and the blend of dyeing, modifying additive melt spinning to make dyable fine denier polypropylene fibre, it is characterized in that: 1) the described dyeing, modifying additive copolyesters that following monomer and corresponding copolymerization weight ratio form of serving as reasons:
1 part of DMT+A
Ethylene glycol+B 0.65-0.80 part
0.-0.15 part of C is wherein: DMT: A=(95-99): (1-5) (molar percentage)
Ethylene glycol: B=(60-90): (10-40) (molar percentage)
A be between the 5-sulfonic acid alkali metal salts (to) rutgers
B is the dihydroxylic alcohols of C3-C6
C is the poly-dihydric alcohol compounds; 2) inherent viscosity of this copolyesters [η] is 0.45-0.60, and fusing point is (200-260) ℃; 3) percentage by weight of this copolyesters is (5-15) % in the blend.
The spinning process that adopts can be a directly melt spinning under the temperature of (220-260) ℃ of blend, also can earlier blend be carried out melt pelletization, again with melt spinning after the particle drying.Winding speed during method spinning provided by the invention can reach (800-3200) m/min, can spin the fine denier polypropylene fibers of filament number for (1.11-2.22) dtex, and fiber or its fabric can boil under normal pressure with disperse dyes and dye dyeing.
In the present invention, the selected and addition of dyeing, modifying additive determines it is key problem in technology.Phase morphology to blend discovers that additive is to be scattered in equably in the polypropylene continuous phase with decentralized photo, and decentralized photo is spheroidal, and boundary is clear smooth, and two kinds of high polymers present phase-separated state in blend.Along with the increase of additive content, decentralized photo farmland density increases.As seen both compatibilities are not only relevant with the molecular structure of additive, and relevant with the content of additive.The inventor finds that when the content of dyeing, modifying additive in blend described in the present invention surpassed 15% (wt.), dispersed phase size obviously increased, whole system compatibility variation.Thereupon, the also obvious variation of the physical properties such as fracture strength of the spinnability of blend and fiber.
On the other hand, the content of additive obviously has direct influence to the dyeability of fiber.The inventor finds, when the content of this copolyesters in blend during less than 5% (wt.), the dye-uptake of fiber obviously descends.After the content of copolyesters improved, the dye-uptake of fiber also rose thereupon.But after content reached 10% (wt.), the rising that continues the content dye-uptake of raising copolyesters but tended towards stability.Therefore the inventor to think that the content of this copolyesters in blend is from 5% (wt.) to 15% (wt.) feasible, but the suggestion optimum content is that 7% (wt.) is to 10% (wt.).In this scope with existing comparatively ideal fiber dye-uptake, the not adding of reason copolyesters and the physical property of spinnability and fiber is had harmful effect again simultaneously.
Secondly, as the dyeing, modifying additive, the chemical composition of copolyesters and inherent viscosity have very important influence to it and polyacrylic compatibility.In each monomer, in fact A replaces DMT in order to part, makes copolyesters have the characteristic of similar ionomer, has more strengthened intermolecular dipole active force.B then replaces ethylene glycol in order to part, and the introducing of B and C makes copolyesters and polypropylene that more similar structure be arranged.B is the dihydroxylic alcohols of one or more C3-C6 in principle, and C is one or more poly-dihydric alcohol compounds.But the inventor thinks that B preferably takes from one or more compounds in propylene glycol, butanediol, pentanediol or the ethylene glycol; C preferably takes from one or more compounds in polyethylene glycol, polypropylene glycol or the polytetramethylene glycol.
The too high or too low spinnability to blend of the inherent viscosity of copolyesters is all unfavorable, finds that by test 0.45-0.60 is a proper scope.And the increase of monomers B content helps the improvement of spinnability, but the increase of monomers B will make that cost significantly increases, and can obtain spinnability and dyeability preferably equally and add monomer C and suitably reduce monomers B.Wherein the addition of monomer A should be appropriate, will influence spinnability to a certain extent when the mol ratio of A and DMT surpasses 1: 19.
Compared with prior art, because dyeing, modifying additive and the polypropylene selected in the method provided by the invention have good process compatibility.Thereby the fiber that not only makes spinning has higher dye-uptake, also has better spinnability simultaneously, and spinning speed can reach (800-3200) m/min, and fiber has the better physical performance.
To come below that the present invention is further described by a series of embodiment, the present invention not only is confined to cited example certainly.
