Abstract
The invention provides a preparation method of a wool anti-pilling finishing agent. The preparation method comprises the following steps: adding polyethylene glycol (PEG3000) and dimethylolbutanoic acid (DMBA) to a reaction container, increasing the temperature to the range from 75 to 80 DEG C, adding isophorone diisocyanate (IPDI) and the catalytic amount of dibutyltin dilaurate and reacting for 2h; adding an end-capping reagent saturated sodium bisulfite solution and reacting for 1-2h, wherein appropriate amount of acetone can be added to control the viscosity of the reaction system; after reducing the temperature to 40 DEG C, adding triethylamine for neutralization, emulsifying in normal-temperature water, adding ethanediamine for chain extending to obtain a water-based polyurethane emulsion, removing the solvent acetone under reduced pressure, adding water to prepare a water agent having the solid content in the range from 20% to 30%. The wool anti-pilling finishing agent provided by the invention is capable of forming a cross-linked network thin film on the surface of the wool fibers to cover the scale structure of the wool fibers, and consequently, friction between the wool fibers is reduced and the effect of anti-pilling is achieved.
Description
Technical field
The present invention relates to a kind of preparation method of fabric finishing agent, particularly a kind of preparation method of wool finishing composition.
Background technology
Wool fiber and woven fabric structure thereof are more loose, and during use, under the effect of various frictional force, the scale structure of wool surface is easy to produce works in collusion and glutinous twining, and the pilling phenomenon occurs, and the impact dress is attractive in appearance, reduces its wear behavior.
Urethane is with the general name of a family macromolecule material of carbamate groups on main chain, aqueous polyurethane refers to take the polyurethane dispersions system that water is dispersion medium, and main raw material is to contain urethano (NH-CO-) and urinate base (NH-CO-NH-) structural unit on the macromolecular chain that generates of polyisocyanates and polyol reaction.Aqueous polyurethane has high strength, rub resistance, the nontoxic excellent properties of Denging, be widely used aspect light textile, leather, coating, tackiness agent, printing etc. a lot.
Summary of the invention
The preparation method who the purpose of this invention is to provide the anti-fluffing antipilling finishing agent of a kind of wool.
What the present invention will solve is the existing poor defect of wool anti-pilling finishing agent finishing effect.
Technical scheme of the present invention is: the invention provides the preparation method of the anti-fluffing antipilling finishing agent of a kind of wool, step is as follows:
In container, add polyoxyethylene glycol (PEG3000) and dimethylolpropionic acid (DMBA), be warming up to 75～80 ℃, add the dibutyl tin laurate of isoflurane chalcone diisocyanate (IPDI) and catalytic amount, reaction 2h; Add the saturated sodium sulfite solution of end-capping reagent, react 1～2h, can add proper amount of acetone to control the viscosity of reaction system; After being cooled to 40 ℃, add the triethylamine neutralization, emulsification in normal-temperature water, add the quadrol chain extension, obtains aqueous polyurethane emulsion, and decompression desolvation acetone, add water and be mixed with the aqua that solid content is 20～30%, can obtain the anti-fluffing antipilling finishing agent of wool.
The mol ratio of described raw material IPDI and PEG3000 is 1.6:1～2.0:1, and the weight percent of DMBA is 4%～6%.
The beneficial effect that the present invention produces is: the agent of the anti-fluffing anti pilling of the aqueous polyurethane used in the present invention, can form the crosslinking net film at wool surface, cover the scale structure of wool fiber, thereby reduced the friction between wool fiber, reached the effect of anti-fluffing anti pilling.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
