25 ± 5 ℃ of product second-order transition temperatures of the present invention, and viscosity (12-25) mpa.s (25 ℃, 20% the aqueous solution, NDJ-79 type viscometer, 1
#Rotating cylinder), PH=6-8, outward appearance is milky white colour band blue light emulsion.
Product of the present invention forms with the monomer polymerization of five kinds of performance complements, embodies excellent slurry quality.Because product of the present invention is designed to have the chemical functional unity structure similar to polyster fibre, therefore to washing and wash yarn have excellent clinging power high containing.Product of the present invention is little to environmental sensibility, and water absorbability is low, causes the serous coat cohesive force to descend with wear resistance with the high moisture absorption of traditional esters of acrylic acid slurry and compares, and its size film property improves greatly.Because the introduction of new type sizing machine, yarn was shortened greatly by the time of serous infiltration, required slurry to have high dense low sticking characteristic, made it to infiltrate fast yarn inside.Product of the present invention promptly possesses above-mentioned performance.Product structure of the present invention contains more ester group in forming, and this material easily is degraded by microorganisms after the destarch, and environmental protection has been played good effect.
In sizing was filled a prescription at present, generally based on PVA and starch, and PVA had tough characteristics as chemical pulp, and starch is hard and crisp as the natural compounds serous coat, to the poor adhesion of washing.Because the serous coat integraty that PVA and starch form is poor, not ideal enough to the provide protection of warp yarn containing high polyester especially.And product of the present invention contains multiple function monomer, on chemical structure, all form with starch by similar structure to PVA, by hydrogen bond and intermolecular forces, served as structural function served as bridge, it is unified whole that PVA and product of the present invention and starch are formed, on size film property, make separately that advantage demonstrates fully, for warp thread provides the fine adhesion layer.
Product of the present invention and PVA, starch are used, and can substitute the PVA of 20-50%, have significantly reduced the usage quantity of PVA and starch.Because after warp thread was dried through starching, consecutive warp was bondd by slurry.During the dried leasing of yarn, consecutive warp is separated by lease rod, has destroyed its original bonding form.If powerful excessive after the slurry film forming, when leasing, can make the warp thread that is subjected to the serous coat protection exposed again, the regeneration feather appears.More serious meeting causes the leasing broken end, and is therefore powerful moderate after the slurry film forming, and keeps favorable elasticity, could improve the integrity of serous coat to the protection of yarn, reduces sizing hairiness, improves sizing wear resistant.Height contained wash and the warp sizing of high-count and high-density kind, adopt the amount of PVA bigger at present in the prescription, though a large amount of uses of PVA, to increasing sizing wear resistant good one side is arranged, but also can bring unfavorable factors such as dried leasing difficulty, filoplume increase simultaneously, therefore in prescription, introduce product of the present invention, because it has moderate intensity and good elongation, therefore reduce the leasing filoplume, wear-resistingly paste clothes with filoplume this provides a new way to contradiction for solving.
