Abstract
The present invention relates to a method for manufacturing a conventional filament and a fine denier filament of a disperse dye dyeable polypropylene fiber by adding high molecular compounds. The added second component is a copolymer of saturated dibasic acid and saturated dibasic alcohol, and the third component is an ethylene-vinyl acetate copolymer, polybutylene terephthalate or polystyrene; the fiber has good spinnability. Light color, medium color and dark color can be dyed by using disperse dye, a dyeing rate reaches more than 80%, and the dyeing rate is increased more under pressure; moreover, multiple color printing and dyeing can be carried out, so the prevent invention has the advantages of good luster, rich color and good hand feeling. A manufactured fine polypropylene fiber denier filament is suitable for producing fabric with favorable wicking effect.
Description
The present invention relates to a kind of polyolefinic manufacture method of dying.Specifically, be the manufacture method of the polypropylene fibre that dyes of available DISPERSE DYES.Can make the polypropylene conventional fibre and thin dawn (1.0～2.0 dtex) fiber of disperse dye dyeable with the present invention.
As everyone knows, on the polypropylene macromolecular chain, nonpolarity group, the degree of crystallinity height, therefore the virgin pp fiber is difficult to dyeing, limited the range of application of polypropylene fibre, at present, commercially available color polypropylene fiber mainly is to produce with the stoste method, but this method incompatibility small lot batch manufacture and changeable market demands, on the other hand, reprocessing can not be dyed, be printed to this method when weaving, also be difficult to make the polypropylene fine denier silk of good wicking effect, for overcoming above-mentioned shortcoming, the fiber worker has carried out a large amount of research work." synthetic fiber industry " 1982, (2) have been reported in the P29 article polyester (PET) or polystyrene and polypropene blended to improve the polypropylene fibre stainability.Studies show that, the dyeable polypropylene fibre that contains 10% polystyrene is 30.6% to the disperse blue of the 1% concentration dye-uptake that dyes 1.5 hours that boils, compare raising with the dye-uptake 18% of polypropylene fibre little, and when adding 10%PET, though dye-uptake brings up to 76%, but, and make spinning, draw conditions harshness because the PET fusing point exceeds about 100 ℃ than polypropylene fusing point.
The objective of the invention is to avoid above-mentioned weak point and provide two or more macromolecule of interpolation can dye component, and wherein a kind of is the low copolyesters of crystallinity, makes that dye-uptake increases, spinnability improves, glossiness is good, chromatogram is abundant, can obtain the disperse dye dyeable polypropylene fibre manufacture method of dark color with boiling dyeing at normal pressure.
The present invention can realize with following measure, is first component with the virgin pp section, and the method that adopts second and third macromolecule of blend can dye component solves the problems referred to above.Second component is the copolyesters that monounsaturated dicarboxylic acid and saturated dihydroxylic alcohols form, but must control its fusion temperature between 100～200 ℃, inherent viscosity: [η]=0.3～0.7, the 3rd component or adopt above-mentioned a kind of copolyesters except that second component, or adopt a kind of in polyethylene vinyl acetate ester, polybutylene terephthalate (PBT), the polystyrene or two kinds.Second and third component adds gross weight: 2～15%, second component and the 3rd components by weight are 0.1～10.Two kinds of high polymers that adopt should have suitable compatibility with polypropylene, these high-polymer moleculars are by the effect between absorption, winding equimolecular, reduced the degree of crystallinity of polypropylene molecule effectively, the loosened structure of former polypropylene fibre, increased the passage of dye molecule to the polypropylene fibre diffusion inside, and be adsorbed, be fixed on fibrous inside, thereby improve dye-uptake.Because the dyed component that adopts is all macromolecular compound, and has a kind of fusion temperature of component to be between 100～200 ℃,, the condition of spinning is not had specific (special) requirements, and can successfully spin the dyeable polypropylene fine denier filament so spinnability improves.
The present invention can also be described in further detail as follows, second component that the present invention is used and the copolyesters in the 3rd component, can obtain by a kind of monounsaturated dicarboxylic acid and two or more saturated diol reaction, or obtain by two or more monounsaturated dicarboxylic acid and a kind of saturated diol reaction, or by two or more monounsaturated dicarboxylic acid and two or more saturated diol reaction acquisition, as long as its melting temperature is between 100～200 ℃.The processing of spinning material can be adopted full comminution granulation, master batch spin processes or direct spinning.Full comminution granulation is with polypropylene chip, all after the blend granulation, removes melt spinning again with second and third component (two, three component weight ratios are 0.1～10) in screw extruder by aforementioned ratio.The master batch spin processes, being about to second component and the 3rd component joins in the virgin pp section by 0.1～10 weight ratio, make second and third can dye 40～70% (weight) that component content is total amount, extrude with the screw extruder blend and to cause master batch, before spinning, add the virgin pp section then again, making second and third constituent content is 2～15% of total amount, melt spinning again.Direct spinning promptly directly fully mixes platform with virgin pp section and second component and the 3rd component, and blending ratio is for example aforementioned, directly enters the spinning machine spinning.Adopt above-mentioned any method all can obtain disperse dye dyeable polypropylene conventional fibre or fine denier filament.
Confirm that through practice disperse dye dyeable polypropylene fibre of the present invention boils when dying under normal pressure, not only can dye light color and medium color, and can dye dark color, to Black (deceiving) E-EX, tens kinds of DISPERSE DYES dye-uptakes such as Blue (indigo plant) E-EX were more than 80% boiling dyeing at normal pressure 1 hour.Dyeing can make dye-uptake higher under pressure.
