QuangFeng SM-370 is a specialized textile auxiliary agent composed of block silicone oil in a weak cationic emulsion form. Its unique molecular structure allows for deep penetration into synthetic fibers, forming a durable, lubricating film that significantly reduces inter-fiber friction. This results in a luxurious "smooth and fluffy" texture ideal for high-end polyester bulky yarns and plush toys. The formula is engineered for stability, offering low yellowing and minimal color change, even on sensitive green fabrics, making it an environmentally friendly choice for factory-direct textile processing.

• Appearance: Pale yellow liquid

• Composition: Block Silicone Oil

• Purity: 38%

• pH Value: 5-7

• Ionicity: Weak cationic

• Package: 120kg, 200kg

• Block Silicone Technology: Provides a more uniform and durable wetting film than traditional amino-silicones, resulting in a premium, non-greasy soft finish.

• Weak Cationic Ionicity: Ensures strong electrostatic attraction to negatively charged synthetic fibers, providing long-lasting wash resistance and durability.

• Superior Fluffiness: Specially formulated to maintain and enhance the "bulky" nature of yarns without causing them to collapse or become heavy.

• Low Color Change: Designed to be "Color Change Green" and anti-yellowing, preserving the original brightness and shade of dyed fabrics.

• Environmental Stability: A pale yellow liquid that is chemically stable and environmentally friendly, meeting modern industrial standards for safe textile manufacturing. 

• Polyester Bulky Yarns: Used during the finishing stage to provide essential lubrication and a soft, voluminous touch to thick yarns.

• Plush Toy Manufacturing: Applied to soft toys to achieve a "velvety smooth" and cuddly tactile experience that enhances consumer appeal.

• Synthetic Fiber Softening: Ideal for polyester and nylon blends where a balance of smoothness and structural integrity is required.

• Knitwear Finishing: Enhances the elasticity and drape of knitted garments, making them more comfortable and less prone to pilling.

• Industrial Yarn Lubrication: Reduces fiber breakage and machinery wear during high-speed spinning and weaving processes.
