Abstract
The present invention is related to polyurethane elastic fiber which is characterized by consisting from polyurethane urea and polyurethane and preparation thereof. The polyurethane elastic fiber of present invention can be used for the usage of swimming suit by way of such excellent anti-chlorine brittle function and thermoset property.
Description
Technical field
The present invention relates to polyurethane elastomeric fiber and manufacture method thereof, cloth and silk and swimsuit.
More detailed saying relates to be suitable for the good polyurethane elastomeric fiber of chlorine resistance of the swimsuit that uses in swimming pool etc.
Technical background
Polyurethane elastomeric fiber has the caoutchouc elasticity of height, because engineering properties such as tensile stress, recovery, thermal property are good, so be widely used in stocking, underwear, sportswear etc.
Yet the clothing product of use polyurethane elastomeric fiber soaks in chlorine bleach for a long time, when washing repeatedly, has the problem of polyurethane elastomeric fiber spring function reduction.
That is, when the swimsuit that uses polyurethane elastomeric fiber soaked in chlorine water repeatedly in the sterilization of water-based pond isoreactivity cl concn 0.5-3ppm, the spring function of polyurethane elastomeric fiber was significantly impaired, produces silk and breaks.
In order to improve the chlorine resistance of polyurethane elastomeric fiber, be polyurethane elastomeric fiber though disclose the polyester that uses the aliphatic poly esterdiol to make raw material, chlorine resistance is insufficient.And, owing to the biologically active of aliphatic polyester is very high, invade the shortcoming that polyester is a polyurethane elastomeric fiber easily so have bacterium, also there is the problem of reduction of swimsuit spring function and easy generation fracture of wire in use or the preservation.The polyethers that uses the minimum PTMEG of biologically active to make raw material is a polyurethane elastomeric fiber, though be subjected to the danger of bacterium initiation embrittlement very little, is the more inferior problem of polyurethane elastomeric fiber but still there is chlorine resistance than polyester.
Polyethers is that polyurethane elastomeric fiber lacks hot residual deformation properties, for this reason, contains the various cloth and the silk of polyurethane elastomeric fiber, all has the problem of hot residual deformation.
That is, because polyurethane elastomeric fiber has very low hot residual deformation efficient, so the silk made from polyurethane elastomeric fiber for hot residual deformation, needs long-time and high-temperature.In the cloth that contains nylon fiber and polyurethane elastomeric fiber, when hot residual deformation temperature is very high, there is the problem that causes the fiber inhomogeneities.This silk fracture strength is little, and is difficult to silk manufacturing is processed into cloth, when wearing the clothing product of being made by this silk, worries the clothing product breakage.This worry is when silk with the little polyurethane elastomeric fiber of fiber number of particularly using in women's socks and swimsuit, particularly remarkable.
Summary of the invention
Purpose of the present invention is exactly in view of above-mentioned the problems of the prior art, and a kind of polyurethane elastomeric fiber and stable method of making this polyurethane elastomeric fiber that swimsuit uses that be suitable for good chlorine resistance and hot residual deformation properties is provided.
The present invention adopts following solution for solving above-mentioned problem.
That is, polyurethane elastomeric fiber of the present invention is characterized in that being formed by polyurethane-urea and polyurethane.
For solving above-mentioned problem, the manufacture method of polyurethane elastomeric fiber of the present invention adopts following solution.
That is, the manufacture method of polyurethane elastomeric fiber of the present invention is characterized in that being that the solution of solute carries out spinning with polyurethane-urea and polyurethane.

[embodiment 9]
Embodiment 2 polyurethane elastomeric fibers and the polyhexamethylene adipamide that obtain are carried out melt spinning, with the polyamide fiber that obtains (50 DENIER/17 thread), the tricot of the 2 kind modes of making through compiling, this tricot is dyeed after the fine finishining, make and be made into swimsuit.
The anti-chlorine embrittlement ability of tricot of dyeing has 122 hours premium properties, and liquor style is also fine.
The swimsuit that obtains is worn in the actual swimming pool tests, the result is up to seeing that the elastic polyurethane silk produces fracture of wire, is 113 hours (wearing 4 times mean value), and durability is good.
[comparative example 1]
Solution A 1 with respect to 1800g adds zinc oxide (this Chuang of micronized zinc oxide chemistry (strain) system), make the zinc oxide that contains 3 weight % in the polyurethane elastomeric fiber, stirred 2 hours, make solution E 1, the speed of deflector roll and up-coiler is taken as 1.20, solution E 1 is carried out dry spinning, polyurethane elastomeric fiber (44 dtexs, 4) is reeled with 540m/ minute speed.The polyurethane elastomeric fiber that obtains is not contain polyurethane, and anti-chlorine embrittlement performance is low, and hot residual deformation is also low, and the result is shown in table 1 in the lump.
[comparative example 2]
Solution B 1 with respect to 1800g adds zinc oxide (this Chuang of micronized zinc oxide, chemistry (strain) system), makes the zinc oxide that contains 3 weight % in the polyurethane elastomeric fiber, stirs 2 hours, makes solution E 2.The velocity ratio of deflector roll and up-coiler is taken as 1.20, solution E 2 is carried out dry spinning, polyurethane elastomeric fiber (44 dtexs, 4) is reeled with 540m/ minute speed.With solution E 2 spinning, spinnability is very poor, and fracture of wire is given birth in not stopping pregnancy.
The polyurethane elastomeric fiber that obtains is not contain polyurethane-urea, though anti-chlorine embrittlement performance height, hot residual deformation is low simultaneously, recovery very poor (stress mitigation and residual deformation are big), and the result is shown in table 1 in the lump.
[comparative example 3]
Use the polyurethane elastomeric fiber of comparative example 1, with embodiment 9 the same tricot and the swimsuits made.The anti-chlorine embrittlement ability of the tricot after the dyeing is very short, has only 86 hours, and the dress of swimsuit in the time of 79 hours, just can see that the elastic polyurethane silk produces fracture of wire with test.
