Description
Technical field
The present invention relates to a kind of method for sizing of low stain spinning sizing agent.
Background technology
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.
The design of sizing technique produces considerable influence to the effect of starching, and current textile sizing generally adopts the method for a starching, and practice shows that starch finishing effect is general, and slurry use amount is large.
Summary of the invention
The object of the invention is to: the defect overcoming above-mentioned prior art, propose a kind of method for sizing of low stain spinning sizing agent.
In order to achieve the above object, the method for sizing of the low stain spinning sizing agent that the present invention proposes, comprises the following steps:
The first step, pour slurry into stock tank, 52 DEG C are heated to slurry temperature in stock tank;
Second step, be soaked in fabric in stock tank slurry in 6 minutes, when soaking, fabric is wrapped on framework and makes it to tighten, and at the uniform velocity rolls fabric, and to make slurry be filled in fabric sufficiently uniformly, squeezing roller pressure is 12KN;
3rd step, taking-up fabric, put into baking oven, dry the moisture on fabric;
4th step, the fabric of oven dry is immersed slurry 3 minutes again, fabric is at the uniform velocity rolled, squeezing roller pressure 14KN;
5th step, taking-up fabric, put into baking oven, dry the moisture on fabric, sizing technique terminates;
The component of described slurry is by mass ratio as follows:
Nano SiO 2 modified starch: 64 parts, albumen slurry: 18 parts, polyvinyl alcohol: 5 parts; Polyacrylate dispersion: 11 parts, modified silicon oil defoamer: 2 parts;
Described nano SiO 2 modified starch adds in deionized water after being mixed with silica flour by hydroxypropyl converted starch, and add NaOH and methyl alcohol, after being hydrolyzed, dry purification obtains, wherein, hydroxypropyl converted starch: silica flour: NaOH: the quality proportioning of methyl alcohol is: 100:5:0.1:0.2;
It is in the sodium hydroxide solution of 0.2% that described albumen slurry adds concentration by soybean protein, elimination sediment after obtains after at the uniform velocity stirring 15 minutes at 45 DEG C;
Described modified silicon oil defoamer by quality proportioning be the polyethers of 1:15 and silicon oil of low hydrogen content modification temperature 1000 DEG C, obtained under modification time 1.5h.
The method for sizing of low stain spinning sizing agent of the present invention also has following improvement:
1, described slurry also comprises the Argine Monohydrochloride of 3 parts by mass.
2, described slurry also comprises the kaolin of 4 parts by mass.
3, described slurry also comprises the sulfamic acid sodium of 3 parts by mass.
4, described slurry also comprises the polyacrylate of 1 parts by mass.
The present invention adopts the mode of twice starching to complete starching to fabric, and has carried out the design of technological parameter for the specific slurry of the present invention, the soak time of mainly slurry groove temperature, twice starching and the pressure size of squeezing roller.Sizing technique of the present invention is especially applicable to a high COTTON FABRIC starching, and starch finishing effect is good.
Containing nano SiO 2 modified starch, albumen slurry, polyvinyl alcohol, polyacrylate dispersion, modified silicon oil defoamer in slurry of the present invention, and proportioning restriction has been carried out to these five kinds of batchings, this kind of slurry has good film forming and permeability, and owing to not containing polyvinyl alcohol, therefore environmental protection more in formula.
In slurry of the present invention, hydroxypropyl converted starch and nano silicon combine, 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, paste liquid is transparent, good fluidity, retrogradation is weak, and stability is high, make the film forming of slurry better, improve the sizing performance of slurry; 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 polyacrylate dispersion, the sizing performance of slurry can be improved further.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.
