The Crucial Role and Advantages of Starch in Textile Processing


Starch, a key functional material in the textile industry, plays a multifaceted role in the processing and finishing of fibers. This article delves into the significant functions of starch in textile processing and highlights the essential advantages it brings to the industry.

1. Primary Component of Sizing: Starch finds extensive application as a primary component in the preparation of sizing agents used in textile processing. As a key ingredient in sizing, starch contributes to the formation of a uniform protective film, enhancing the strength and abrasion resistance of fibers and creating favorable conditions for subsequent processing steps.

2. Wetting and Water Absorption Properties: Starch's excellent wetting and water absorption properties facilitate superior dye and chemical agent absorption by fibers. This is crucial for ensuring even penetration and fixation of treatment agents during processes such as dyeing, finishing, and coating.

3. Adhesion and Protective Coating: The adhesive properties of starch enable it to uniformly adhere to the fiber surface, forming a protective coating. This contributes to improved wear resistance, wrinkle resistance, and durability of fibers, extending the lifespan of textile products.

4. Viscosity Regulation and Flow Control: Starch's viscosity can be controlled by adjusting the concentration of sizing solutions, allowing for the modulation of interactions between fibers. This is essential for controlling the appearance and handfeel of textiles and achieving better control of fluidity during the production process.

5. Environmental Sustainability: Compared to some synthetic sizing agents, starch stands out as a natural and environmentally friendly choice. In the current context of emphasizing sustainable development and green production, choosing starch as a material in textile processing contributes to reducing environmental impact and aligns with the principles of sustainability.

Conclusion: Starch, with its multifaceted advantages, plays an irreplaceable role in textile processing. Its application in sizing enhances fiber performance, laying a solid foundation for the production of high-quality and durable textiles. As the demand for sustainable practices continues to rise, the future outlook for starch in the textile industry appears promising.
