Abstract
The present invention discloses electrostatic resisting sol gel finishing liquid which comprises the ingredients of 4 to 50 weight percentages of gamma-glycerol triglycidyl ether oxopropyl trimethylsilane, and 0 to 80 weight percentages of ethanol, and the rest is a hydrochloric acid water solution. The electrostatic resisting sol gel finishing liquid can be used for preparing electrostatic resisting dacron. The present invention uses a reagent containing epoxy base groups as a raw material for preparing colloidal sol, and the padding finishing method suitable for textiles is used. Thus, nanometer gelatin particles can be formed on inner and outer fiber surfaces by only carrying out the heat treatment from 100 to 180 DEG C to the textiles. The hygroscopic effect of combined water and epoxy base groups in the gelatin particles are used for obtaining the purpose of electrostatic resistance. The present invention can be used for a plurality of water washing times, and has lasting effect.
Description
Technical field
The present invention relates to antistatic collosol and gel dressing liquid and the application in the preparation anti-electrostatic polyester thereof.
Background technology
The basic principle of so-gel technology is metal alkoxide or inorganic salts hydrolysis are directly formed or to form colloidal sol with fixed attention through separating, and makes the solute gelation then, again with gel drying, bake, remove organic principle, obtain inorganic material at last.
Be mainly used in preparing on glass, superfine powder and the film at present, adopt 300～800 ℃ high-temperature roasting, when the system film, adopt smooth surfaces such as glass, metal, plastics to carry out coating as matrix, form continuous film in stromal surface, combine by Van der Waals force between film and the carrier, do not have chemical bond.It is unpractical that such technology is used on the textiles, because textiles can't bear high-temperature roasting, therefore researchs and develops a kind of new antistatic collosol and gel dressing liquid, to satisfy the needs of field of textiles development, will have very significant social and economic implications.
Summary of the invention
One of technical problem to be solved by this invention is to disclose a kind of antistatic collosol and gel dressing liquid;
Two of the technical issues that need to address of the present invention provide the application of above-mentioned antistatic collosol and gel dressing liquid in the preparation anti-electrostatic polyester, to satisfy the needs of the parties concerned.
Basic design of the present invention is such:
Utilize the bound water in the gel and the cooperative effect of epoxide group, textiles is played antistatic property.
The component and the weight percent content of antistatic collosol and gel dressing liquid of the present invention comprise:
γ-glycidyl ether oxygen propyl trimethyl silane 4%～50%;
Ethanol 0%～80%
The aqueous hydrochloric acid solution surplus
Wherein, the concentration of aqueous hydrochloric acid solution is 0.0001～0.5mol/L.
The preparation method comprises the steps:
Hydrochloric acid solution is added to the mixture of γ-glycidyl ether oxygen propyl trimethyl silane and ethanol, stirs ageing 24 hours under the room temperature.
Above-mentioned antistatic collosol and gel dressing liquid can be used for preparing anti-electrostatic polyester, and application process comprises the steps: dacron two is soaked two and rolls pressure 2～3kg/cm in above-mentioned dressing liquid
2, liquid carrying rate 50～60% with 80 ℃～130 ℃ preliminary dryings 2～3 minutes in heat setting machine of the cloth after the arrangement, baked 2～3 minutes at 130 ℃～180 ℃ then.
The present invention selects for use the reagent that contains epoxide group as feedstock production colloidal sol, the method for sorting of this suitable textiles is padded in employing, only need textiles is carried out 100～180 ℃ heat treatment, can form the nanogel particle on the inside and outside surface of fiber, utilize the hygroscopic effect of bound water in the gel particles and epoxide group and reach anlistatig purpose, it is lasting repeatedly to wash effect.
This antistatic method is different with the antistatic mechanism of existing antistatic finishing agent, and this method reaches anlistatig purpose by the cooperative effect of the self-contained bound water of epoxide group in the gel molecular (hygroscopic effect) and gel particles.
Advantage of the present invention:
1, baking temperature is low, only need bake at 100～180 ℃, than low 200～600 ℃ of the baking temperature of sol gel process, adopts traditional spinning post-finishing technology, and simple to operate, equipment is easy to get.
2, because gel nano particle and fiber have very strong adhesion, after fabric is repeatedly washed, still has the excellent antistatic energy.
3, the collosol and gel antistatic finishing agent is synthetic simple, with low cost, environmental protection and energy saving.
