YH-1108 Nylon-Spandex Degreasing Agent for Textile

Specifically developed and optimized for open-width continuous production lines, this product is highly compatible with high-speed open-width desizing and degreasing machines. It is suitable for the continuous long-range pretreatment of nylon-spandex and polyester-spandex stretch fabrics, primarily targeting equipment anti-fouling and low-pH mild processing scenarios.

  • Hardware specifications
  • Physical and Chemical Properties

    1. Appearance: Colorless to light yellow liquid

    2. Ionicity: Anionic / Non-ionic

    3. pH Value (1% aqueous solution): 2.0–4.0

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

     

    Features & Advantages

    1. Special surfactants endow it with highly efficient washing capabilities, used to remove mechanical oils, mineral oils, and silicone oils attached during synthetic fiber weaving. It exhibits excellent emulsifying effects and anti-redeposition properties, especially against dimethyl silicone oil on spandex.

    2. Formulated with an exclusive anti-fouling recipe for long-range continuous machines, it removes oil stains while preventing silicone oil and oily sludge from adhering to rollers, fabric guide rollers, and bath tanks. This reduces equipment downtime for cleaning and ensures stable open-width mass production, while effectively eliminating defects such as dyeing white spots and horizontal bars on stretch fabrics.

    3. Featuring an acid-alkali dual-stable system, it maintains excellent washing, emulsifying, and degreasing capabilities in both weakly acidic stock solutions and neutral/alkaline working fluids, making it compatible with various open-width pretreatment processes.
