Abstract
The invention relates to a method for manufacturing polyether type easily-dyed spandex fibers. It mainly solves the defect that the finished product in the prior art is not dyed by common dyes. It is mainly characterized in that the polyurethane or polyurethane solution which takes polyurethane or polyurethane urea as the main component is prepared by
Is used as an end-capping reagent, and is made into spandex fiber through spinning. It has the good effects of good dyeing property and high dyeing fastness of the finished product, and can be widely used for manufacturing spandex fibers with excellent dyeing property.
Description
The present invention relates to a kind of manufacture method of spandex fibre, particularly a kind of manufacture method with polyether-type spandex fibre of good chromatophilia energy.
Spandex is a kind of elastomeric textile fabric, now has been widely used in the knitting and woven elastic fabric.Yet because the molecular structure non-coloring gene of spandex itself, so usually dyestuff is not had the shortcoming of dying.In order to improve the dyeability of spandex silk, it is introduced that some companies contain the trivalent nitrogen compound and carry out copolymerization and improve its dyeability with adding abroad, but that this method still exists dye-uptake is big, the deficiency of dyefastness difference.Another kind method was added the trivalent nitrogen compound in the condensate in the past, but this method in the back manufacturing procedure operational problem takes place easily, produces powder, causes broken end.
Purpose of the present invention be exactly propose a kind of have good chromatophilia can the manufacture method of spandex fibre, to solve the shortcoming that existing in prior technology spandex manufactured goods dye on not common dyestuff.
Technical scheme of the present invention is achieved in that a kind of manufacture method of chromophilous polyether spandex filament, with polyurethanes or polyurethanes urea the polyurethane or the polyurethane solutions of Main Ingredients and Appearance, make spandex fibre through spinning, it is the organic compound with following structure that the end group of polyurethane blocks agent:
In the formula: R
1, R
2Alkyl or isoalkyl for C atomicity 1-4, R is the alkylene of C atomicity 1-12, it 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, N such as N-dimethyl-ethylenediamine, N-dialkyl group alkylene diamine, particularly R are that alkylene below 4 is better for the C atomicity; Above-mentioned is that the polyurethane of Main Ingredients and Appearance is with number average molecule 1 000-4000 with polyurethanes or polyurethanes urea, and fusing point is that PTMEG below 60 ℃ and organic diisocyanate and the organic diamine of molecular weight below 400 are that raw material is made.
Advantage and good effect that the present invention had are, dyeability and dyefastness with the prepared spandex fibre of this method significantly improve, strong, also having with light stabilizer, antioxidant etc. and using has cooperative effect and the light resistance feature of fibres modified except that product dyed thereby is distinct.And have in forming process or in the process of back and do not break down, do not produce poor properties, whiteness is low, multiple advantage such as no color differnece.
Below with embodiment the present invention is further elaborated:
Embodiment 1: with 1950 parts of the polytetramethylene ether diols of molecular weight 1950 and 4,500 parts of 4-methyl diphenylene diisocyanates are at 70 ℃ of reaction 45min, obtain the prepolymer that two ends have isocyanate group, after adding 4487 parts of dimethyl formamide dissolving formation solution, be cooled to 8 ℃, add 74 part 1 while stirring, the 2-propane diamine is dissolved in 983 parts of dimethylformamides formed 1, and 2-propane diamine solution carries out chain propagation reaction.1,2-propane diamine solution adds 90% to, when viscosity reaches about 360PaS (20 ℃), add N, N-dimethylated propyl diethylenetriamine/dimethyl formamide be 21 parts/72 parts solution in condensate, react with free isocyanate groups.Adding acetic anhydride acid anhydride/dimethyl formamide afterwards is 10 parts/72 parts solution-stabilized viscosity.Making viscosity is that 340PaS (20 ℃) solid content is 32% polyurethane solutions.Spinning obtains the spandex fibre of 116dtex then, has good dyeability.
Embodiment 2, and with quadrat method N, the N-dimethyl-ethylenediamine substitutes N according to embodiment 1, and the N-dimethylated propyl diethylenetriamine can make the good 116dtex spandex fibre of dyeability equally.
