The composite heat-yellow discolouration resistant finishing agent is low in cost, simple in treatment process and high in industrial application value.
Description
Technical field
The present invention relates to the compound heat resistanceheat resistant xanthochromia of a kind of polyamide fibre, spandex and BLENDED FABRIC thereof finishing agent, specifically improve polyamide fibre, spandex and BLENDED FABRIC HEAT SETTING thereof and mold pressing yellowing and a color change, compound anti-yellowing change finishing agent with low cost, easy to use.
Background technology
Polyamide fibre is again polyamide fiber or nylon, has a lot of amide groups in molecular structure.Spandex is again polyurethane fiber, has a lot of carbamate groups in molecular structure.Polyamide fibre and spandex have many good physical and mechanical propertiess, in weaving and other industrial circles, are widely used.But it is as poor in heat resistance that polyamide fibre also exists, at light and heat, lower easy yellowing, the shortcoming such as become fragile.Particularly in high temperature process process, during as heat setting and pressing mold, easily yellowing and generation look become, affect the presentation quality of product, also can produce serious influence to the physical and mechanical properties of polyamide fibre and spandex simultaneously, its wearability is reduced greatly, so the arrangement of heat resistanceheat resistant xanthochromia is a very important link in its dyeing and finishing process.Polyamide fibre, spandex and BLENDED FABRIC thereof, in the hot procedures such as high temperature thermo-setting and pressing mold, add the agent of heat resistanceheat resistant xanthochromia can prevent oxidation under its high temperature and tendering, improve yellowing and color change that the effect due to light and heat, moisture, nitrogen oxide causes.
Although have in the market some for polyamide fibre, the commodity heat resistanceheat resistant xanthochromia agent product that spandex and BLENDED FABRIC thereof arrange, as the Umidol PAT of Switzerland's Clariant and Umidol UWP, the Solpon SPDX of Germany's Baume chemical industry (Dr. TH. B HME), the DM-2915(B of Guangdong dolantin chemical industry), the anti-yellowing change agent of the nylon high temperature HJW-AY SUPER of the prosperous TEXTILE CHEMICALS of the TF-621 of development of evil in febrile disease chemical industry and Heng Xin, Shenzhen Co., Ltd etc., but these products all do not provide structure and the composition of the agent of heat resistanceheat resistant xanthochromia, and these commodity heat resistanceheat resistant xanthochromia agent product prices are higher, be unfavorable for applying aborning.
In the prior art, have people (CN101250812A) to use smooth agent, emulsifying agent, detergent, additive to form a kind of anti-yellowing change finish and have obtained good anti-yellowing change effect, but the method try out in dacron, to polyamide fibre spandex inapplicable.
The present invention relates to a kind of compound heat resistanceheat resistant xanthochromia of polyamide fibre, spandex and BLENDED FABRIC thereof finishing agent that polyamide fibre, spandex and BLENDED FABRIC HEAT SETTING thereof and mold pressing yellowing and color change, good water solubility, easy to use, with low cost, applicable industry are applied that improves.Synergist is wherein one or more in soluble small molecular organic amine compound, and as urea, acetyl guanidine, dimethylguanidine, biuret etc., particularly preferably soluble small molecular organic amide compounds is wherein urea.Synergist is reducing inorganic phosphorus-containing compound, and as one or more in inferior sodium phosphate, sodium phosphite, pyrophosphorous acid sodium etc., particularly preferably reducing inorganic phosphorus-containing compound is wherein inferior sodium phosphate.Primary antioxidant is one or more in glutaric acid two hydrazides, adipic dihydrazide, pimelic acid two hydrazides, suberic acid two hydrazides etc., particularly preferably adipic dihydrazide wherein.By adding synergist and synergist, the compound heat resistanceheat resistant xanthochromia finishing agent the present invention relates to, compare with the commodity heat resistanceheat resistant xanthochromia finishing agent Umidol UWP of Switzerland Clariant, when finishing agent concentration is identical, when reaching better heat resistanceheat resistant xanthochromia effect, cost is cheaper, has higher industrial application value.
Summary of the invention
The present invention has adopted synergist, synergist and primary antioxidant to be re-dubbed the compound heat resistanceheat resistant xanthochromia of polyamide fibre, spandex and BLENDED FABRIC thereof finishing agent, can overcome the problem of prior art, significantly improve polyamide fibre and spandex and BLENDED FABRIC thereof yellowing and the color change problem in process, with low cost, easy to use, there is higher industrial application value.
