Its preparation principle
One, starch
1, high amylose starch drying and forming-film caudacoria is tough and tensile, intensity is high, and deflection is with folding, but poorly water-soluble, solution is unstable, and retrogradation is strong, needs high temperature steaming gelatinization, can effectively prevent treating compound from moving in starch-type treating compound.And low amylose starch is soluble in water, solution-stabilized, but film forming caudacoria is fragility, and frangible, intensity is low, easily moves in treating compound.
Starch in starch treating compound need through modification, to improve its cohesiveness and film strength further, improves that it is water-soluble, reduces viscosity.Often use in starch-type treating compound two or more starch with the use of, to reach desired properties.
2, the high amylose starch of modification and low amylose starch mixture is used can to learn from other's strong points to offset one's weaknesses in performance, remix cationic active agent, this treated starch can form the higher film of intensity, and film elasticity is good, good with the fiberglass surfacing affinity of negatively charged ion, can be evenly distributed on fiber.Can also reduce treating compound migration and reduce treating compound preparing, deposit, formed in use procedure the tendency of gel.Treating compound film fast drying, does not get damp again, and in the later process course of processing, fiber breakage is few, lousiness is few, powder falling is also few.
Two, oils
In starch-type treating compound, oils plays a part lubrication and plasticized starch, is mainly hydrogenated vegetable oil, as soybean oil.It has good intermiscibility with water soluble starch after emulsification, not only has lubrication and improves the effect of starch film toughness, also can in warm wash, promotes the burning of starch treating compound film to become estranged volatilization, is convenient to the aftertreatment of glass-fiber-fabric.Microcrystalline wax emulsion is fine to the oilness effect of yarn, and treating compound can be reduced the transport property for the treatment of compound by there is hard Microcrystalline Wax particle in cladding, reduces the fluffing of yarn, is both the water ratio that can also control when glass fibre moves back solution.
Three, emulsifying agent
Oils emulsifying agent be tween (polyoxy ethylene sorbitol fatty alcohol) with department Pan (sorbitan fatty alcohol) with the use of, to obtain best HLB value.
Four, cationic active agent
The additive that cationic active agent is treating compound is used in starch treating compound, for the glyoxaline compound that stearic acid and polyethylene polyamine are formed, its use can reduce the surface tension for the treatment of compound, is conducive to carrying out smoothly of wire-drawing operation, reduces lousiness, broken end when twisting thread.
Five, membrane-forming agent
Membrane-forming agent (polyvinyl alcohol) and starch use, can increase treating compound bonding boundling power, improve precursor powerful, improve wear resistance, reduces lousiness and starch comes off moving back solution, in weaving process of twisting thread.
