Performance and Characteristics

  • 1. It can effectively prevent nylon, polyester and their blended fabrics from yellowing during packaging, transportation or storage.

  • 2. It can prevent the reaction between nitrogen oxide gas and phenols, and has excellent inhibition ability on phenol yellowing.

  • 3. The color becomes smaller, which will not affect the fabric feel.

  • 4. Good stability, acid resistance, alkali resistance and hard water resistance.




Special product to minimize the tendency of phenolic yellowing of white and light shade fabrics, which can be developed during the storage in plastic wrappings.

  • What is textile thickener?

    Thickeners used in textile printing are high molecular weight viscous compounds gave a sticky paste with water, which impart stickiness and plasticity to the printing paste. These thickeners facilitate to preserve the design outlines without spreading even under high pressure.

  • Why thickener is used in printing?

    Thickeners impart adhesivity and plasticity to the printing paste which can be applied on to the fabric without spreading and hold- ing the dye molecule at the desired place until the transfer of dye into the fabric and its fixation are complete.

  • What are chemical thickeners?

    Thickening agents, or thickeners, is the term applied to substances which increase the viscosity of a solution or liquid/solid mixture without substantially modifying its other properties; although most frequently applied to foods where the target property is taste, the term also is applicable to paints, inks, ...

  • What are the two main types of thickeners?

    There are two main types of thickening agent: starch-based (typically modified maize starch) and gum-based.
