Applications of Modified Starch in Industrial Manufacturing

As a specialist producer of modified starches, we supply high-quality ingredients to leading industrial manufacturers across diverse sectors. Our modified starch products meet demanding process requirements, and our technical service supports customer applications throughout the value chain. Below, we detail major industrial application fields and their technical integration.

3. Textile Sizing and Finishing

Our modified starch is widely used in the warp-sizing process of woven textile production. It forms a flexible film that protects yarns from abrasion and mechanical stresses during weaving. This prevents yarn breakage, reduces production downtime, and ensures high weaving efficiency, especially with cotton and blended yarns. Downstream users adjust dosage and viscosity to optimize sizing for different fiber types and loom speeds. We support continuous process integration for modern high-speed looms and eco-friendly after-wash removal.

• 8–15% solids on yarn weight for cotton sizing
• 12–20% for blended polyester-cotton yarns
• Adjusted based on yarn count, loom type, and desired film properties

Downstream process integration

• Prepared as aqueous solution, applied during warp-sizing operation
• Coats yarns before entry to weaving process
• Removes easily in post-weaving scouring or desizing bath, supporting eco-compliance

Final product types

• Denim fabrics
• Shirting materials
• Home textiles and technical fabrics
• Industrial canvas and geotextiles

4. Construction and Building Materials

Within the construction sector, modified starch functions as a binder, water retention agent, and plasticizer in dry-mix mortars, tile adhesives, and joint compounds. Our products support improved workability, reduce sagging, and extend open time for installers. We partner with certified construction material manufacturers, emphasizing compliance with regional building chemistry standards.
