Operation principle of the present invention is: in textile industry, the warp thread before weaving is the slurry axle of first-class yarn slurry slurries; For slurry axle, at first need to modulate the slurries of yarn slurry, again with the yarn slurry slurries that modulate, warp thread is obtained through starching, mud jacking, prebake, oven dry.In weaving process, although weave effect can relate to various all multifactor, the key factor that influences weave effect depends on the sizing on the slurry axle and sizing effect on the slurry axle depends on that the slurries of yarn slurry, the slurries effect of yarn slurry depend on viscosity.Because: viscosity is too high, slurries can not fully be penetrated into yarn inside, surperficial coating surplus, warp thread surface serous coat is peeled off easily and do not come off, cause simultaneously warp thread wear-resisting and opening is unclear, increase the warp broken end, only consequently cause the yam surface starching, make serous coat come off, reduce weaving efficiency easily in the weaving process; Viscosity is low excessively, though can guarantee infiltration, the coating effect of warp thread is reduced greatly, makes that filoplume increases, the rate of sizing descends, and makes in the weaving process that Warp opening is unclear, influence is wovenly carried out smoothly, also can cause and can not weave seriously the time.With regard to the viscosity of yarn slurry slurries, the key factor that influences it is a temperature.Because: in the raw material of yarn slurry slurries, starch is topmost raw material in all raw materials, and starch exists not gelatinization, half gelatinization, three kinds of states of gelatinization under Temperature Influence; Viscosity change can take place to gelatinization in starch never gelatinization, and the starch granules diameter mean value of not gelatinization is the 10-20 micron, after the cold water profit rises, only increases 10-15%; And the starch granules of process gelatinization but is original 50-100 times; In the farinaceous size of half gelatinization, the granule of existing ungelatinized, again gelatinization is arranged bulky grain.The critical-temperature of not gelatinization of starch and gelatinization according to the difference of starch kind, and does not wait at 45-80 ℃; Low temperature half gelatinization treatment temperature is 45-60 ℃ in of the present invention, makes slurries be in middle low temperature half gelatinization state like this, regulates slurry viscosity by gelatinization degree, under the half gelatinization state, exists when fully having guaranteed starch granule and bulky grain starch.Under above-described prerequisite, the present invention is in the technical process to warp sizing, the temperature that keeps room temperature to 60 ℃, thereby make in the process of starching, mud jacking, short grained starch is easy to be penetrated into the inside of yarn and the short grained starch of bulky grain and part just can be coated on the surface of yarn uniformly, like this, and infiltration and the combination that coats, can reach desirable starching and require and actual effect, thereby meet the slurry axle that many kinds, high-quality require for weaving of weaving provides.
Owing to adopted technical scheme provided by the invention, and the above-mentioned operation principle of the present invention is described, makes the present invention compare with existing known technology, has following beneficial effect:
1, because machinery used in the present invention and apparatus, be general machinery equipment and apparatus that the industry is being used at present, thereby obtained cost low, be convenient to operate, be beneficial to the beneficial effect of applying.
2, since in of the present invention low temperature half gelatinization handle and to the starching of warp thread etc., all under middle cryogenic conditions, carry out, this compares with common employed 98 ℃ of High Temperature High Pressure starchings, thereby has obtained that mechanical bearing is not fragile, the rubber surface of pressure roller is difficult for aging beneficial effect.
3, because the condition that the slurries of modulation yarn of the present invention slurry have adopted middle low temperature half gelatinization to handle and the starching of warp thread has also been adopted middle low temperature, make in the process of starching, mud jacking, short grained starch is easy to be penetrated into the inside of yarn and the short grained starch of bulky grain and part just can be coated on the surface of yarn uniformly, the such infiltration and the combination of coating, can reach desirable starching and require and actual effect, thereby obtain to provide the beneficial effect that meets the slurry axle that many kinds, high-quality require for weaving of weaving.Simultaneously, yarn slurry slurry viscosity of the present invention is adjustable, thereby has also obtained to comply with the development of consuming situation, the beneficial effect that adapts to many kinds, high-quality demand for development in the textile industry.
4, since the slurries of modulation yarn of the present invention slurry adopted middle low temperature half gelatinization to handle and the condition of middle low temperature also adopted in the starching of warp thread, thereby obtained the energy-and time-economizing, alleviated operating personnel's working strength, improved the beneficial effect of working environment.
5, because the present invention has adopted half gelatinization starching, hygrometric state viscosity reduces, thereby has obtained to help dividing sinker, reduces the beneficial effect of the generation of sizing secondary filoplume.
6,, thereby obtained to improve the beneficial effect of sizing quality because the present invention has adopted the high drying means in first low back.
7,, thereby the high temperature gelatinization method that to avoid traditional and the beneficial effect that directly carries out many deficiencies, defective and the drawback of warp sizing method have been obtained with starch emulsion because above each bar of the present invention is described.
