Description
One, technical field
The present invention relates to a kind of preparation method of polyether-type colorful spandex fiber, belong to spandex fibre preparation method technical field.
Two, background technology
Spandex is a kind of elastomeric textile fabric, and its extension at break is generally 500%-700%, and elastic recovery rate is generally greater than 90%, the fracture strength height, therefore, spandex fibre be applied to knitting widely and woven fabric in.Yet because non-coloring group in the molecular structure of spandex itself, so, under common dyeing condition, spandex silk dyeing difficulty need carry out twice dyeing, and COLOR FASTNESS is low, if dyeing condition is too fierce, also can cause the spandex silk to melt disconnected phenomenon, influence the elasticity of fabric, this causes many difficulties for the dyeing and finishing processing of enterprise.
Three, summary of the invention
The objective of the invention is to solve the problem of the spandex dyeing difficulty that exists in the existing spandex silk dyeing process, a kind of pigment or dyestuff of adding in spandex fiber stoste is provided, make the spandex silk of production itself have color, in the following process process, do not need spandex fibre is dyeed once more the preparation method of prepared spandex fibre lovely luster, colorful spandex fiber that dyefastness is high.
The present invention is achieved by the following technical solutions:
The preparation method of colorful spandex fiber, its special character is to comprise following operation:
(1) provides poly-(tetramethylene ether) glycol;
(2) provide 4,4 '-methyl diphenylene diisocyanate;
(3) will gather (tetramethylene ether) two pure and mild 4,4 '-methyl diphenylene diisocyanate hybrid reaction obtains poly-(tetramethylene ether) glycol of end-blocking, wherein the mol ratio of vulcabond and poly-(tetramethylene ether) glycol is (1.55-2.15): 1;
(4) providing amide compound is solvent, and poly-(tetramethylene ether) glycol of mixed dissolution end-blocking forms solution;
(5) poly-(tetramethylene ether) glycol solution and the mixture of chain extenders of mixing end-blocking form polyurethane urea solutions, and the solid content of polyurethane urea solutions is 25%-35%;
(6) select colouring agent, colouring agent preliminary treatment, colorant match, dispersion get debita spissitudo suspension or painted stoste;
(7) suspension or painted stoste are added polyurethane urea solutions, stir, obtaining with polyurethanes and polyurethanes carbamide compound is the spandex fiber solution of repetitive;
(8), form colorful spandex with the spandex fiber solution dry spinning.
Described solvent is selected from dimethyl formamide or dimethylacetylamide.
Described mixture of chain extenders comprises: the ethylenediamine of 50 to 85 molar percentages, the 2 methyl pentamethylenediamine of 15 to 50 molar percentages;
Described colouring agent is the pigment of organic or inorganic, and it is to keep Stability Analysis of Structures, nondiscolouring in the clock time in 250 ℃, 5 minutes that pigment satisfies in temperature; The amount of adding pigment in the fiber depends on the type of the used pigment of desired color harmony, and the amount of the pigment that adds in the fiber is the 0.1-4% of polyurethane solutions solid content percentage by weight.
Described pigment can be selected at least a in the following pigment: AZO pigments, phthalocyanine pigment, heterocycle and condensed ring ketone pigment and inorganic pigment, pigment be through after the milled processed, make its major diameter ≦ 5 microns.
Be benzimidazolone heterocyclic pigment preferably in the described AZO pigments; Be copper phthalocyanine, halogenated copper phthalocyanine pigment preferably in the phthalocyanine pigment; Heterocycle and condensed ring ketone pigment is Wei dioxazines pigment, 1 preferably, 4-diketopyrrolo-pyrrole class pigment.
Use in the spandex fiber solution dry-spinning method hot nitrogen or air in circular or square path to the spinning solution oven dry, through drawing-off, oil, reel and make finished product.
In order to control the polyurethane-urea molecular weight, to use a kind of single functionality chain terminating agent at least, chain terminating agent is the primary amine or the secondary amine of single functionality, as dimethylamine, diethylamine, two-n-butylamine, n-butylamine, n-hexylamine, cyclohexylamine, monoethanolamine and their mixture, preferred chain terminating agent such as n-butylamine, cyclohexylamine, diethylamine, monoethanolamine.
Various additives also can add in the polyurethane solutions after chain extension finishes, as TITANIUM DIOXIDE DELUSTRANT, and antioxidant Tinuvin 622, UV stabilizer T inuvin 234 etc.
The preparation method of colorful spandex fiber of the present invention, solved the problem of spandex silk dyeing difficulty in the printing and dyeing process, the spandex silk of production itself has color, the spandex fibre lovely luster, the dyefastness height does not need spandex fibre is dyeed once more in the following process process.
Four, the specific embodiment
The present invention is described in further detail below in conjunction with specific embodiment, but embodiment must not be interpreted as the limitation of the present invention that goes up in all senses.
Embodiment
