Description

A kind of textile fabric of UV resistance
Technical field
The present invention relates to technical field of textile fabric, and in particular to a kind of textile fabric of UV resistance.
Background technique
Since the major part of solar ultraviolet radiation is absorbed by molecules such as Ozone in Atmosphere, oxygen, nitrogen, in earth table Face, ultraviolet radioactive weaken significantly.But in recent years, it is largely discharged by the fluoride gas of representative of freon, atmosphere is smelly Oxygen layer reduces filtering and barrier action of the ozone layer to ultraviolet light by irreversible destruction.Scientific investigations showed that smelly Oxygen layer destruction is one of the main reason for human skin carcinogenesis rate is constantly soaring.Because the radiation of ultraviolet light can change groups of cells The structure and function divided, when the ultraviolet radiation that cell is subject to, which reaches, to be suffered, which can lose the communication with other cells In turn apoptosis occurs for ability.Therefore, it is to prevent the effective measures of cutaneum carcinoma that protection skin, which resists ultraviolet radiation,.To human skin The ultraviolet radiation damaged is mainly long-wave UV radiation (UVA, 320~400nm of wavelength) and ultraviolet B radiation spoke Two kinds of (UVB, 290~300nm of wavelength) is penetrated, UVA radiation accounts for 90 or more the percent of solar radiation, and the radiation transmission is extremely The surface layer of skin and skin corium, to accelerate the actinic aging of skin.In contrast, UVB radiation proportion is lower, but its It is easier to make skin tanning, causes DNA Damage, and then cause skin cancer.
There are the anti-radiation clothes of anti-ultraviolet radiation in the market in ultraviolet radiation in order to prevent.It is common in existing market The technological means of production ultraviolet-resistant fabric is predominantly mixed into antiultraviolet material in spinning to achieve the effect that antiultraviolet. But this mode is helpless to the improvement of subsequent product since polymerization.
Summary of the invention
The purpose of the present invention is to solve the above problems, provide a kind of textile fabric of UV resistance.
In order to achieve the above object of the invention, the invention adopts the following technical scheme:
A kind of textile fabric of UV resistance, the UV resistance coating including tissue layer and coating on the fabric, the UV resistance Coating includes the component of following parts by weight meter: 30-35 parts of unsaturated polyester (UP), hydroxy-end capped poly- methyl-silicone oil 20-25 parts, and poly- second 2-5 parts of alkene pyrrolidone, 3-8 parts of organic silicon emulsion, 0.1-0.5 parts of modified or unmodified melanin powder, modified meerschaum 3-8 parts of powder, 0.2-0.5 parts of titanium dioxide, 3-7 parts of lactide, 5-20 parts of solvent.
The present invention is changed existing Uvr Protective Fabric fabric and is arranged using antiultraviolet, and melanin powder sheet is utilized Melanin is applied to textile technology field by the ultraviolet resistance that body has;Melanin of the invention belongs to natural UV resistance Light absorbers, melanin will not decompose generation noxious material in the use process of fabric and impact to the health of human body;With This simultaneously as melanin itself there are also blue light is absorbed so that the color of fabric in the sun is more mild soft and graceful;This The ultraviolet protection coefficient of the Uvr Protective Fabric fabric of invention can reach 48 or more, transmitance < 5% of ultraviolet light;Of the invention is anti- Ultra-violet layer is located at fabric inner layer, is guaranteeing that ultraviolet resistance is persistent simultaneously, the surface layer for not influencing fabric is beautiful Property is adapted for use on clothes, on shoes and hats, umbrella and curtain etc., is especially suitable for doing parasol, curtain etc..
Present invention improves over the compound systems of unsaturated polyester resin, for the deficiency of coating toughness and intensity, this hair It is bright to be especially added with modified meerschaum powder, using the modified high length-diameter ratio in surface, nanometer and submicron-scale, with unsaturated-resin And other materials preparation can have the coating of excellent toughness and intensity and endurance can by the modification to sepiolite Significantly improve coating material enhancing and toughening effect.
Preferably, the UV resistance coating includes the component of following parts by weight meter: 30-32 parts of unsaturated polyester (UP), hydroxyl Poly- methyl-silicone oil 20-23 parts of base sealing end, 4-5 parts of polyvinylpyrrolidone, 3-5 parts of organic silicon emulsion, modified black element powder 0.1-0.3 parts, 5-8 parts of modified meerschaum powder, 0.2-0.5 parts of titanium dioxide, 3-5 parts of lactide, 5-20 parts of solvent.

(2) by the mixed solution of the polymethyl siloxane of sepiolite powder and mass concentration 10-12%% and ethyl acetate, It is stirred the dispersion liquid that is uniformly dispersed to obtain, wherein the mass ratio of polymethyl siloxane and ethyl acetate is 1:2;Then to dispersion liquid Middle addition accounts for the ascorbic acid that dispersion liquid quality is 0.5-1%, and is ultrasonically treated 20 minutes, simultaneously 60 DEG C of deionization washing after filtering It dries below;
(3) then combination solution is used to mix, combination solution is neopelex and silane coupling agent Ethanol solution, the mass concentration of neopelex are 5%, and the mass concentration of silane coupling agent is 20%, at 40 DEG C Then lower mixing 30min is filtered and is dried to obtain modified meerschaum powder at 70-80 DEG C.
Unmodified sepiolite powder is easy to reunite, is unfavorable for following process in this way, and to coating material since particle is thinner Performance raising have adverse effect.Inventor, can by above-mentioned processing mode by finding after long-term experimental study It effectively solves the problems, such as the unity of sepiolite powder, lays a good foundation for the effect performance of sepiolite in the coating.Simultaneously as even Join the effect of agent, sepiolite is combined more uniform after hardening with other components, and bond strength is good, avoids the coating being prepared into The strength of materials reduces the generation of cracking.
Preferably, the unsaturated polyester (UP) is vinylite or bisphenol A-type unsaturated polyester (UP).
Preferably, solvent is toluene, acetone or butanone.
Preferably, the partial size of the modified meerschaum powder is 100-150nm.
Preferably, the partial size of the melanin powder is 50-100 nanometers.
Preferably, the method for modifying of the melanin powder specifically:
(1) 2-5 parts of melanin powder are dispersed in 100 parts of dimethyl sulfoxides, and are wherein being added 5-15 parts 1,2- propylene oxide and 0.3-0.5 parts of citric acid, then exist, and are stirred to react 2-5h at 30-50 DEG C;
(2) it is added 20-30 parts of n-butanol in systems again, 1-5 parts of dodecyl bromide stirs 30min at 110 DEG C, Then 20-30 parts of dimethyl silicone polymer and 3-5 parts of disodium ethylene diamine tetraacetate is added, then stirs 30- at 120 DEG C 60min;It is filtered, washed and dried;Drying temperature is 70-80 DEG C;
