YH-1104 Nylon-Spandex Degreasing Agent

Specially developed for nylon-spandex and polyester-spandex stretch fabrics, this product is universally compatible with batch equipment (such as jig dyeing and rope overflow dyeing machines) and conventional open-width continuous pretreatment degreasing processes. It serves as a general-purpose degreasing product for the regular production of nylon-spandex fabrics.

  • Hardware specifications
  • Physical and Chemical Properties

    1. Appearance: Colorless to light yellow liquid

    2. Ionicity: Anionic / Non-ionic

    4. Solubility: Can be diluted with water in any proportion and disperses uniformly in aqueous solutions.

     

    Features & Advantages

    1. Formulated with highly efficient emulsifying surfactants, it completely removes mechanical lubricating oils, mineral oils, and spinning silicone oils attached during weaving. It possesses strong emulsifying and decomposing power against dimethyl silicone oil on the surface of spandex fibers, ensuring stable basic anti-redeposition performance.

    2. It simultaneously removes oil and inhibits the redeposition of oil stains onto the fibers, significantly reducing white spots and color unevenness defects in conventional nylon-spandex fabric dyeing, making it suitable for the stable mass production of conventional stretch fabrics.

    3. Resistant to neutral, weakly alkaline, and moderately alkaline environments, it maintains stable emulsification and washing performance across the entire range, making it compatible with conventional acid and alkali pretreatment processes.
