Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
At present, the slurry that textile mills are generally used has PVA, converted starch and polyacrylic slurry. ThisA little slurries have top performance separately under suitable regain.
The 1799 type PVA that the present invention selects are complete alcoholysis type, a polar functionalities hydroxyl in its structure(-OH), has good hygroscopicity, and Fig. 1 is the moisture absorption of PVA1799 under different relative humidityCurve. From Fig. 1, it can also be seen that, in the time that relative humidity is greater than 74%, PVA hygroscopicity significantly improves,This is because relative humidity water higher than 74% time has enough driving forces to destroy amorphous region, causes moisture absorptionRegain significantly rises.
Starch is the macromolecular compound being formed by connecting by α-Isosorbide-5-Nitrae glucoside key by α-D glucose, belongs to polysaccharideClass material, feature is in molecule, to contain many hydroxyls, has good hygroscopicity, Fig. 2 is 100% horseThe sucting wet curve of bell potato side chain etherification starch. As seen from Figure 2, in the time that relative humidity is greater than 70%,Starch size hygroscopicity significantly improves, and this is because under high humility, the concentration of the outside hydrone of starch sizeHeight, interior molecules concentration is little, the trend that the naturally oriented slurry molecular surface of water adheres to, this trend is with interiorThe increase of outer moist gradient and increasing, the regain of starch size also increases thereupon.
The slurries that the present invention adopts PVA1799 and 100% potato side chain etherification starch to be mixed, energyEnough realizing woven reason under low humidity (relative humidity 60%) condition is: adopting PVA1799When the slurries of preparing with 100% potato side chain etherification starch carry out starching, too high relative humidity can makeToo much moisture enters into the serous coat on sizing, has reduced the cohesive force of serous coat, causes the brute force of sizingDecline with wearability, meanwhile, farina natural moisture content is than the high 2-3% of cornstarch water content,So adopt the yarn of PVA and potato starch pulp, need to just can not give under high relative humidityThe good resistance to flexibility of serous coat on sizing. And in existing sizing process, mostly select PVA1799, corn to becomeProperty starch and multi-component polymerized polyacrylic slurry make mixed serum, warp thread is carried out to sizing, and surveysThe performance of examination sizing is that 70-74%, sized warp moisture regain are 8.3% slashing strength when above in relative humidityThe highest, wearability is best. This is because polyacrylic slurry is competence exertion under high regain onlyIts effect, and high regain must have the environment of high humility, otherwise sizing will moisture releasing, and sizing can not be protectedHold higher regain, and then impact is weaved.
One of the present invention is suitable for woven sizing method under low-humidity environment, comprises formula of size and sizing workSkill, its formula of size is: be made up of following component by mass percentage: polyvinyl alcohol 28%～82%,Converted starch 72%～18%, the content sum of above each component is 100%; Wherein, converted starch is 100%Potato side chain etherification starch, PVA is 1799 types.
