Textile industry — Warp sizing
Acidized starch
Features and advantages
1. Low degree of polymerization, strong coagulability, high strength size film, good wear resistance of sizing
2. Viscosity of serous fluid is low, good liquidity, suitable for making high concentration size pulp with low viscosity
3. Easy to form an even size film
4. Short size pulp boiling time

Functions
1. Make yarn hairness smooth, form protective size film on the yarn surface, improve yarn wear resistance
2. Enhance the adhesion between monofilaments, enhance the effect of cluster
3. Make yarn surface smooth, reduce friction resistance during weaving
4. Increase the stiffness of all-cotton textiles

Applications
1. As main sizing agent for cotton yarn, viscose yarn and ramie yarn
2. Mixed with PVA or polyacrylate to form mixture sizing agent, for blended yarn, such as polyester/cotton, polyester/viscose, polyester/linen, etc.
3. Used for fabric finishing

Oxidized starch
Features and advantages
1. Low viscosity, good liquidity, strong penetration, can be used in making high concentration size pulp with low viscosity
2. Size pulp is stable
3. Size film has good breaking strength
4. Size film is even and clear, can reduce starch lump
5. Size film is easily soluble in water, easy for desizing
6. The affinity for fiber is higher than native starch, and the adhesive force for cotton yarn and blended yarn (polyester/cotton, polyester/viscose) is higher than native starch

Functions
1. Make yarn hairness smooth, form protective size film on the yarn surface, improve yarn wear resistance
2. Enhance the adhesion between monofilaments, enhance the effect of cluster
3. Make yarn surface smooth, reduce friction resistance during weaving

Applications
1. Oxidized starch can be main size agent for medium and fine cotton yarn and linen yarn. The physical mechanical properties and manufacturability of its sizing is better than native starch
2. Oxidized starch has good compatibility with PVA, polyacrylate synthetic size. The mixture size agent is widely used to warp sizing for polyester/cotton, polyester/cotton, polyester/viscose, polyester/wool, and other blended yarn

Textile industry --- Printing gum
1. High whiteness
2. The printing gum has good rheological properties, low viscosity and very stable
3. Good plasticity, low degree of congelation
4. Good film-forming property, film is transparent and tough
