Warp sizing is the key link of weaving engineering, and the object of sizing mainly improves the ABRASION RESISTANCE of yarn, reduces filoplume, suitably increases the brute force of yarn, reduces degree of stretching, and to bear the mechanicals efforts that warp thread is subject in weaving process, improves the weavability of yarn.
The slurry of current warp sizing mainly contains the large slurry of starch, polyvinyl alcohol (PVA) and polyacrylic three.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 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 the homopolymers of acrylic monomer, copolymer and blend, its viscosity is lower, good fluidity, good adhesiveness is had to synthetic fiber, 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: the defect overcoming above-mentioned prior art, propose a kind of spinning sizing agent preparation method being applicable to dacron.
In order to achieve the above object, the spinning sizing agent preparation method being applicable to dacron that the present invention proposes, comprises the steps:
The first step, carbamate starch is mixed with silica flour after add in deionized water, and add NaOH and methyl alcohol, after being hydrolyzed, dry purification obtains nano SiO 2 modified starch, wherein, carbamate starch: silica flour: NaOH: the quality proportioning of methyl alcohol is: 110:6:0.2:0.4;
It is in the sodium hydroxide solution of 0.1% that second step, soybean protein add concentration, elimination sediment after obtains albumen slurry after at the uniform velocity stirring 20 minutes at 45 DEG C;
3rd step, according to weight proportion, by nano SiO 2 modified starch 50 parts, 26 parts, albumen slurry, water-based copolyether ester 20 parts, glycerine 2 parts, modified silicon oil defoamer 2 parts is poured in agitator and is uniformly mixed, and to obtain final product;
Described modified silicon oil defoamer by quality proportioning be the polyethers of 1:17 and silicon oil of low hydrogen content modification temperature 110 DEG C, obtained under modification time 1.5h.
The spinning sizing agent preparation method that the present invention is applicable to dacron also has following improvement:
1, described water-based copolyether ester is prepared with the following method: get 120 weight portion rutgerses, 15 weight portion ethylene glycol, 400 weight portion relative molecular masses are 1500 polyethylene glycol, 100 weight portion relative molecular masses are 500 ~ 1000 poly-(1,2-propylene glycol), 62 weight portions 1, the catalyst butyl titanate of 2-dihydroxy-3-N-morpholinopropanesulfonic acid sodium and 0.3 weight portion drops in polymer reactor, agitating heating, make material melts and carry out ester exchange reaction, when methyl alcohol quantity of distillate is 90% of theoretical amount, terminate ester exchange reaction; Then by product of transesterification reaction with nitrogen replacement 5 times, then be warming up to 222 DEG C gradually, behind 2 hours continuously decompression, and reaction 3 hours under 245 DEG C and 90Pa pressure, last inflated with nitrogen eliminates vacuum, obtains water-based copolyether ester.
2, in the 3rd step, the sodium carboxymethylcellulose of 5 parts by mass is also poured into agitator.
3, in the 3rd step, the sulfamic acid sodium of 2 parts by mass is also poured into agitator.
4, in the 3rd step, the polyacrylate of 2 parts by mass is also poured into agitator.
Present invention process is simple, containing nano SiO 2 modified starch, albumen slurry, glycerine, modified silicon oil defoamer in the spinning sizing agent of preparation, and proportioning restriction has been carried out to these four kinds of batchings, the slurry obtained has good film forming and permeability, experiment shows that the slurry obtained is particularly suitable for the starching of dacron, and owing to not containing polyvinyl alcohol, therefore environmental protection more in formula.
In the slurry that the inventive method prepares, carbamate starch and nano silicon are combined, on the one hand, carbamate starch belongs to dacron starching; Nano silicon contributes to starch dispersion in the slurry on the other hand, also improves the sizing performance of slurry to a certain extent.The albumen slurry added and modified starch promote mutually, and with the use of glycerine, the sizing performance of slurry can be improved further.Water-based copolyether ester in slurry can significantly improve the serviceability of modified starch size, improves result of use.For front four kinds of materials, the present invention selects modified silicon oil defoamer as defoamer, can effectively eliminate the foam produced in sizing 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.
