Abstract
The invention relates to a method for manufacturing spandex fiber easy to dye and resistant to chlorine, which solves the defects of poor dyeing property and poor chlorine resistance of finished products in the prior art. The main feature of the invention is that the polyurethane or polyurethane solution with polyurethane or reduced carbamate urea as main component isN－R－NH2The invention is an end-capping agent and a chlorine-resistant auxiliary agent added with (ROAr) nZ, the finished product has the remarkable characteristics of excellent dyeability and good chlorine resistance, and can be widely applied to the industrial manufacture of spandex fiber easy to be dyed and resistant to chlorine.
Description
The present invention relates to a kind of manufacture method of spandex fibre, particularly a kind of manufacture method with easily dyeing and chlorine fastness spandex fibers.
Spandex is a kind of elastomeric textile fabric that has, and has now been widely used in knitting and woven elastic fabric.Yet due to non-coloring group in the macromolecular structure at spandex itself, so conventionally dyestuff is not had to the shortcoming of dying.For improving its dyeability, abroad some companies adopt to add containing trivalent nitrogen compound and carry out copolymerization, but that this method exists dye-uptake is large, the shortcoming that dyefastness is poor.Another method was added trivalent nitrogen compound in condensate in the past, but the method, in rear manufacturing procedure, operational problem easily occurs, and produces powder, causes broken end.The chlorine resistance of existing its manufactured goods of manufacture spandex fibre method is very poor on the other hand.Especially after making swimsuit, be subject to the erosion of active chlorine in swimming pool can lose its intensity and elasticity.
Object of the present invention is just to provide a kind of method of manufacturing spandex fibre, to overcome the existing defect of existing method and to make manufactured goods have the characteristic of easily dying resistance to chlorine.
Technical scheme of the present invention is achieved in that a kind of manufacture method of easily dyeing and chlorine fastness spandex fibers, to have
(in formula: R1, R2 are alkyl or the isoalkyl of C atomicity 1-4, R is the alkylene of C atomicity 1-12) organic compound of chemical constitution is end-blocked agent, with number-average molecular weight 1000-4000, fusing point be 60 ℃ of following PTMEGs or polyester-diol and organic diisocyanate and the organic diamine of molecular weight below 400 be in the polyurethanes made of raw material or the polyurethanes urea condensate that is Main Ingredients and Appearance or polymer solution molten add there is (ROAr) nZ (in formula: Z represents that C atomicity is the alkylene of 0-12, C atomicity be 1 or 2 tertiary alkylene or-S-or
, or-N=N-or-O-; Ar representative
; R represents that C atomicity is the alkyl of 1-4; N=1-3) alkoxy benzene derivatives of the 0.1-15% with respect to weight polyurethane of structure, after filtration, spinning makes finished product after deaeration.Wherein, end-blocked agent can be N, N-dimethylated propyl diethylenetriamine, N, N-diethyl propyldiamine, N, N-diethyl ethylenediamine, N, N-dibutyl propane diamine, N, N-dibutyl ethylenediamine, N, the N such as N-dimethyl-ethylenediamine, N-dialkyl group alkylene diamine, particularly R are that C atomicity is that alkylene below 4 is better.Polyurethane or polyurethane solutions also can coordinate with the stabilisation amount of the interpolation composition such as light stabilizer, antioxidant, delustering agent, weather resisting agent containing trivalent nitrogen, fire retardant, pigment on the other hand.
Advantage and effect that the present invention has are, owing to having added the effective auxiliary agent of resistance to chlorine and having there is the end-blocked agent with color base group, make manufactured goods with the method gained there is product dyed thereby distinct and strong, the advantage that chlorine resistance is good, and can and use the light resistance that has cooperative effect and improve fiber with light stabilizer, antioxidant etc.And have and do not break down in forming process or in rear process, do not produce poor properties, the advantage of no color differnece.
With embodiment, the present invention is further elaborated below:
Embodiment 1: with 1950 parts of molecular weight 1950 polytetramethylene ether diols and 4, 500 parts of 4 '-methyl diphenylene diisocyanates are at 70 ℃ of reaction 45min, obtain the prepolymer that two ends have isocyanate group, add 4487 parts of dimethyl formamides to dissolve and form after solution, be cooled to 8 ℃, add while stirring 74 part 1, 2-propane diamine is dissolved in 1 of 983 parts of dimethylformamide gained, 2 propane diamine solution carry out chain propagation reaction, when 1, when 2-propane diamine solution additive 90% viscosity reaches about 360PaS (20 ℃), add N, N-dimethylated propyl diethylenetriamine/dimethyl formamide is that 21 parts/72 parts solution are in polymer solution, free isocyanate group is disappeared.Adding afterwards acetic anhydride acid anhydride/dimethyl formamide is 10 parts/72 parts solution-stabilized viscosity, and making viscosity is the polyurethane solutions A that 340PaS (20 ℃) concentration is 32%.Then with respect to polyurethane solutions A100 part, add 0.32 part of light stabilizer GW540, 0.32 part of antioxidant 3114, 0.16 part of antioxidant bisphenol-A phosphite ester, containing 0.48 part of resistance to marquis's agent MS-100 of trivalent nitrogen, 0.24 part of the reactant of Laur hydrazine and bis-phenol two glycerin ethers, 0.24 part of polymethylacrylic acid diethyl amino ethyl ester, 0.32 part of two (4-methoxyphenyl) dimethylmethane, it is 32% polyurethane solutions that 6 parts of 0.51 part, magnesia and dimethyl formamides are deployed into solid content, weave and obtain the spandex fibre A of 116dtex, to after its chlorine damage, measure its strength retention and stress conservation rate is respectively 98.2% and 95.0%, and be easy to dyeing.
Embodiment 2, with 1950 parts of the polytetramethylene ethers of molecular weight 1950 and 4,500 parts of 4-methyl diphenylene diisocyanates obtain at 70 ℃ of reaction 45min the prepolymer that two ends have isocyanate group, add 4487 parts of dimethyl formamides to dissolve and form after solution, be cooled to 8 ℃, add while stirring with 74 part 1,2-propane diamine is dissolved in 983 parts of dimethyl formamides prepared 1, and 2-propane diamine solution carries out chain propagation reaction.When 1, when 2-propane diamine additive 90%, viscosity reach about 360PaS (20 ℃), add N, N-diethyl ethylenediamine/dimethyl formamide is that 23 parts/72 parts solution are in polymer solution, react with free isocyanate group, adding afterwards acetic anhydride acid anhydride/dimethyl formamide is 10 parts/72 parts solution-stabilized viscosity, and making viscosity is the polyurethane solutions D that 340PaS (20 ℃) solid content is 32%.With respect to polyurethane solutions D100 part, add 0.32 part of light stabilizer GW540 again, 0.32 part of antioxidant 3114, containing 0.48 part of the weather resisting agent MS-100 of trivalent nitrogen, 0.24 part of the reactant of Laur hydrazine and bis-phenol two glycerin ethers, 3.4 parts of 0.24 part of polymethylacrylic acid diethyl amino ethyl ester and dimethyl formamides are deployed into, concentration is 32% polyurethane solutions, through weaving, makes 116dtex spandex fibre D, has equally good chlorine resistance and chromatophilia.
