Description

Application Scope

This size is dedicated for polyester filament yarn, pure polyester yarn, and Terylene yarn with polyester content more than 60%.

Characteristics

Excellent adhesion performance

Having similar molecular structure and excellent adhesion performance with polyester, that the adhesion force better than that of PVA, acrylic ester and modified starch, etc

Better water-soluble
Having a good solubility in water above 80℃, no precipitation, no crust. Having a good miscibility with the starch, PVA, acrylic ester, no precipitation, no stratification.

Low viscosity and good stability
Adapt to the high concentration, high pressure, low viscosity sizing process. Easy to get good penetration, fiber cohesion, hairiness appressed.

Good sizing film
Firm, smooth and transparent, the sizing film disconnected uniformly in lease with little regeneration yarn hairiness. Effectively reduce the rate of warp breakage and improve the loom efficiency.

Cost effective
Providing the quality of weaving is satisfied, the sizing was used in an 0.5 times of PVA dosage.

Green and Eco friendly
Degraded by alcohol, water, alkali, light and microbe. The performance of degradation is better than PVA and the
dosage is 0.5 times of PVA in weaving to reduce the cost of sewage treatment.

Uses

Formula
On the basis of existing formula, substitute 1kg dedicated size for polyester for 2kg PVA, supplemented with starch or modified starch to keep the content of solid unchanged.

Add the appropriate amount of oiling agent, antistatic agent, to ensure that the rate of sizing(actually the rate of sizing will be slightly lower).
Mashing
Add an appropriate amount of water to mashing bucket. Then add starchy and dedicated size for polyester after the stirring apparatus started, stir sufficiently and then heat to above 95℃,
next cook for 30 minutes or more with small valve on. Add the appropriate amount of oiling agent, antistatic agent, then mix them to boil. Finally adjust the volume and viscosity to use.

Announcements

1. Using as directed by professional technician.
2. Assistant size containing divalent metal or heavy metal salts should be avoided in size formula, water of high hardness should also be avoided using, if the hardness of water for size mixing is high, demineralization is needed. Do not use NaOH as decomposing agent in mixing. The PH value of the slurry should be between 6 to 7, and not too low or too high, pay special attention on acrylic acid and alkalinity of starch denaturing agents. The viscosity of the original formula should basically be consistent.
