Background technology
Finishing functions is the important means that promotes the textiles wearability, increases the textiles added value, mainly comprise anti-ultraviolet, anti-pilling, wrinkle resistant, antibiotic, refuse water, refuse oil, felt proofing, fire-retardant, softness etc.Because the mechanism of every kind of finishing functions has nothing in common with each other, therefore often need to adopt different finishing auxiliarieses.Along with developing rapidly of consumption demand, requirement improves constantly to functions of textile fabrics, and especially textiles being had polyfunctional requirement simultaneously increases gradually.
Anti-pilling and the arrangement of anti-ultraviolet are textile two kinds of arrangements often adopting with polyester cotton.Anti-ultraviolet arrangement is main by ultraviolet absorption and reflection are realized, mainly adopts Oxybenzone, hydroxy-phenyl benzotriazole, hydroxyphenyl-triazine etc.; In addition, nano titanium oxide also has certain ultraviolet shielded effect.Pill resistant finish is an approach to reduce interfibrous slippage or to increase surface of cotton fabric fineness, and biology enzyme, polyacrylate, polyurethane, organo-silicon compound etc. are main auxiliary agent.
When Oxybenzone, hydroxy-phenyl benzotriazole, hydroxyphenyl-triazine and biology enzyme carried out with the bath processing to textiles, biological enzyme activity can be affected, and weakens finishing effect; And during auxiliary agent couplings such as the anti-ultraviolet finishing agent of tradition and polyacrylate, polyurethane, organo-silicon compound, colloidal sol, will reduce the diffusivity of preventing the ultraviolet finishing agent again.Therefore at present textiles realizes that if desired anti-pilling is functional with two kinds of anti-ultraviolets, must carry out a kind of arrangement earlier and realize once putting in order after a kind of function again and realize another kind of function, processing technology complexity, water consumption power consumption, increase cost.
Therefore study the anti-pilling of textiles, anti-ultraviolet mechanism, the development of new finishing agent is realized single bath process, reduces the pollution of chemical assistant to environment, cuts down the consumption of energy, and this is one of main developing direction in current finishing functions field.
Summary of the invention
At the deficiency of existing processing technology, the invention provides a kind of anti-pilling that can make by single bath process, the finishing functions of textile fabrics agent of anti-ultraviolet.
One of purpose of the present invention is to provide the anti-pilling of this kind, anti-ultraviolet finishing agent.Described finishing agent is got by the method preparation that may further comprise the steps:
(1) the titanium alkoxide is dissolved in the organic solvent, the solution with gained adds in the acidic aqueous solution again, stirs, and obtains mixture;
(2) silicon alkoxide is joined in the mixture that obtains in the step (1), stir, obtain clear solution, promptly described finishing agent;
Perhaps get by the method preparation that may further comprise the steps:
(1) acid, silicon alkoxide is soluble in water successively, stir, obtain mixture;
(2) the titanium alkoxide is dissolved in the organic solvent, the solution of gained joins in the mixture that obtains in the step (1), stirs, and obtains clear solution, promptly described finishing agent;
In two kinds of above-mentioned preparation processes, preferred first kind.
More specifically,
Described silicon alkoxide is selected from least a in C4~C20 alkoxy silane; Preferred at least a in C4~C9 alkoxy silane.More specifically examples of compounds comprises: methyl silicate, ethyl orthosilicate, γ-glycidyl ether oxygen propyl trimethyl oxosilane, vinyl trimethyl oxosilane, vinyl triethyl group oxosilane, γ-(methacryloxy) oxypropyl trimethyl oxosilane; Wherein, preferred γ-glycidyl ether oxygen propyl trimethyl oxosilane, vinyl trimethyl oxosilane.

Described acid is selected from least a in inorganic acid or the water miscible organic acid; Preferred at least a in hydrochloric acid, nitric acid, formic acid.
Described organic solvent is to form chelate structure and water-soluble organic solvent with the titanium alkoxide, is selected from least a in the hydroxyl organic ligand compound; Preferred at least a in acetic acid, acetylacetone,2,4-pentanedione.Wherein, the consumption of each component is as follows:
The mol ratio of described titanium alkoxide and water is 1: (1~200); Preferred 1: (30~100);
The mol ratio of described titanium alkoxide and organic solvent is 1: (0.5~100); Preferred 1: (4~10);
Described titanium alkoxide is 1 with the mol ratio of acid: (0.001~10); Preferred 1: (0.01~0.1);
The mol ratio of described titanium alkoxide and silicon alkoxide is 1: (0.01~100); Preferred 1: (1~10).
The effect of finishing agent of the present invention is the mating reaction of each reagent, and its consumption can be regulated in the scope of broad, and effect is not had much affect.
It is raw material that the present invention adopts titanium alkoxide and silicon alkoxide, utilize them that hydrolysis and polycondensation reaction take place in water, generation is uniformly distributed in the water, the nano particle that contains Si-O-Si, Ti-O-Ti, Si-O-Ti key, because the Ti-O key has excellent uvioresistant performance, and Si-O has two dimension and three-dimensional valence bond structure simultaneously, the two in conjunction with after also can improve the anti-pilling of fabric.In addition, because nanostructured has than bigger serface, can be spontaneous absorption fast takes place, assemble at fabric face so do not need to add any adhesive in the finishing agent, and safer environmental protection has also reduced cost simultaneously.
Two of purpose of the present invention is to provide the preparation method of this kind finishing agent, and this preparation method is the single bath process process, may further comprise the steps:
(1) the titanium alkoxide is dissolved in the organic solvent, the solution with gained adds in the acidic aqueous solution again, stirs, and obtains mixture;
(2) silicon alkoxide is joined in the mixture that step (1) obtains, stir, obtain clear solution, promptly described finishing agent;
Perhaps described method may further comprise the steps:
(1) acid, silicon alkoxide is soluble in water successively, stir, obtain mixture;
(2) the titanium alkoxide is dissolved in the organic solvent, the solution of gained joins in the mixture that obtains in the step (1), stirs, and obtains clear solution, promptly described finishing agent.
In the described operation, the interpolation of its material and alr mode are common processing method.
Three of purpose of the present invention is to provide the purposes of this kind finishing agent, and described finishing agent is used to put in order pure cotton fabric, or chemical fibre and cotton blended fabric.
Wherein, described chemical fibre is selected from least a in polyester fiber, polyamide fiber, the polypropylene fibre.Textiles in the described step (2) is cotton or chemical fibre and cotton blended fabric, and wherein chemical fibre comprises polyester fiber, polyamide fiber, polypropylene fibre etc.
When using finishing agent of the present invention to put textiles in order, can finishing agent of the present invention be handled on the textiles by padding or flood single bath process, liquid carrying rate is 40~100%, and oven dry baked in 100~130 ℃ 0.5~3 minute then, promptly finished the arrangement process.
The present invention has the following advantages:
(1) uses titanium alkoxide and silicon alkoxide to prepare textile finish, adopt and pad or flood the single bath process arrangement, improve the anti-pilling of textiles, uv resistance energy simultaneously.
(2) effect of finishing agent of the present invention is the mating reaction of each reagent, and its consumption can be regulated in the scope of broad, and effect is not had much affect, and makes working condition simplify, and technical process is not harsh.
(3) use this finishing agent and can realize that textiles prevents pilling, the arrangement of anti-ultraviolet, simplified processing technology, reduced consumption, reduced processing cost, improved production efficiency water, the energy by single bath process.
