Abstract
The invention relates to a textile size preparation method suitable for a silk fabric. The method comprises the steps of mixing hydroxypropyl modified starch and silicon powder to obtain a mixture, adding the mixture into deionized water, adding sodium hydroxide and methyl alcohol, performing hydrolysis, and then performing drying purification to obtain nano silicon dioxide modified starch; adding soybean proteins into the sodium hydroxide solution, stirring the materials at constant speed at the temperature of 46 DEG C for 15 minutes, adjusting the pH value to 7-8 by 30% hydrochloric acid, and filtering out precipitates to obtain protein slurry; stirring and mixing the protein slurry, the nano silicon dioxide modified starch, a polyacrylate emulsion and a modified silicon oil defoaming agent in a stirrer to obtain the textile size. The textile size prepared by the method disclosed by the invention is high in film-forming property and permeation property and excellent in sizing performance, and is particularly suitable for sizing of a silk fabric; furthermore, the textile size does not contain polyvinyl alcohol, so that the textile size has an environment-friendly effect.
Description
Technical field
The present invention relates to a kind of spinning sizing agent preparation method who is applicable to real silk fabric.
Background technology
Warp sizing is the key link of weaving engineering, and the object of sizing is mainly to improve the ABRASION RESISTANCE of yarn, reduces filoplume, suitably increases the brute force of yarn, reduces degree of stretching, the mechanicals efforts being subject in weaving process to bear warp thread, the weavability of raising yarn.
The slurry of warp sizing mainly contains starch, polyvinyl alcohol (PVA) and the large slurry of polyacrylic three at present.Starch is natural polysaecharides high polymer, and Size-Film Forming Properties is good, strong with natural fabric affinity, is easy to destarch; But starch size slashing strength is inadequate, not wear-resisting, and also inadequate with polyster fibre affinity.Polyvinyl alcohol pulp serous coat is powerful large, and pliability is good, and slurry fluidity is good, but polyvinyl alcohol is difficult to destarch, and big for environment pollution.Polyacrylic acid size is the general name of homopolymers, copolymer and the blend of acrylic monomer, its viscosity is lower, good fluidity, synthetic fiber are had to good adhesiveness, can be mixed well with starch, PVA slurry, be applicable to the warp sizing of each fibrid, but polyacrylic acid size price is high, raise the production cost of printing and dyeing enterprise.
Summary of the invention
The object of the invention is to: overcome the defect of above-mentioned prior art, propose a kind of spinning sizing agent preparation method who is applicable to real silk fabric.
In order to achieve the above object, the spinning sizing agent preparation method who is applicable to real silk fabric that the present invention proposes, comprises the steps:
The first step, after being mixed with silica flour, hydroxypropyl converted starch adds in deionized water, and add NaOH and methyl alcohol, after being hydrolyzed, dry purification obtains nano SiO 2 modified starch, wherein, hydroxypropyl converted starch: silica flour: NaOH: the quality proportioning of methyl alcohol is: 100:6:0.1:0.2;
It is in 70% ethanolic solution that second step, soybean protein add concentration, at the uniform velocity stirs after 15 minutes at 46 DEG C, adopts salt acid for adjusting pH value that concentration is 30% to 7-8, obtains albumen slurry after elimination sediment;
The 3rd step, according to weight proportion, by 70 parts, albumen slurry, 20 parts of nano SiO 2 modified starch, 8 parts of polyacrylate dispersions, 2 parts of modified silicon oil defoamers are poured in agitator and are uniformly mixed, and to obtain final product;
The polyethers that described modified silicon oil defoamer is 1:15 by quality proportioning and silicon oil of low hydrogen content, 1000 DEG C of modification temperatures, make under modification time 1.5h.
The spinning sizing agent preparation method that the present invention is applicable to real silk fabric also has following improvement:
1,, in the 3rd step, also pour the Argine Monohydrochloride of 6 parts by mass into agitator.
2,, in the 3rd step, also pour the sulfamic acid sodium of 3 parts by mass into agitator.
3,, in the 3rd step, also pour the polyacrylate of 1 parts by mass into agitator.
Technique of the present invention is simple, the spinning sizing agent of preparation is taking albumen slurry as main, taking nano SiO 2 modified starch, polyacrylate dispersion as auxiliary, modified silicon oil is as defoamer, and these four kinds of batchings have been carried out to proportioning restriction, and the slurry of acquisition has good film forming and permeability, experiment shows that the slurry making is particularly suitable for the starching of real silk fabric, and owing to not containing polyvinyl alcohol, therefore environmental protection more in formula.
The composition of real silk is protein, and the present invention prepares in slurry, and albumen slurry and protein have good affinity, and therefore effect of impregnation is better; And in formula, hydroxypropyl converted starch and nano silicon are combined, on the one hand, hydroxypropyl has hydrophily, can weaken the internal hydrogen bond strength of starch granules structure, make it be easy to expand, gelatinization is easy, sticks with paste liquid transparent, good fluidity, a little less than retrogradation, stability is high, makes the film forming of slurry better, has improved the sizing performance of slurry; Nano silicon contributes to the dispersion of starch in slurry on the other hand, has also improved to a certain extent the sizing performance of slurry.The albumen slurry and the modified starch that add promote mutually, and the polyacrylate dispersion being used in conjunction with, and can further improve the sizing performance of slurry.Plant material for first three, the present invention selects modified silicon oil defoamer as defoamer, can effectively eliminate the foam producing in starching process, make slurry more fully with clothing in contact, improve starching efficiency, save slurry.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
The present embodiment is applicable to the spinning sizing agent preparation method of real silk fabric, comprises the steps:
The first step, after being mixed with silica flour, hydroxypropyl converted starch adds in deionized water, and add NaOH and methyl alcohol, after being hydrolyzed, dry purification obtains nano SiO 2 modified starch, wherein, hydroxypropyl converted starch: silica flour: NaOH: the quality proportioning of methyl alcohol is: 100:6:0.1:0.2;
It is in 70% ethanolic solution that second step, soybean protein add concentration, at the uniform velocity stirs after 15 minutes at 46 DEG C, adopts salt acid for adjusting pH value that concentration is 30% to 7-8, obtains albumen slurry after elimination sediment;
The 3rd step, according to weight proportion, by 70 parts, albumen slurry, 20 parts of nano SiO 2 modified starch, 8 parts of polyacrylate dispersions, 2 parts of polysiloxane-modified polyethers, 6 parts of Argine Monohydrochlorides, 3 parts, sulfamic acid sodium, 1 part of polyacrylate is poured in agitator and is uniformly mixed, and to obtain final product.
In the present embodiment, the polyethers that modified silicon oil defoamer is 1:15 by quality proportioning and silicon oil of low hydrogen content, 1000 DEG C of modification temperatures, make under modification time 1.5h.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
