QuangFeng SF-340 is an advanced textile finishing agent engineered with a unique ternary copolymer structure. Unlike standard softeners, this polyester elastic softener emulsion focuses on "fluffy rebound," allowing synthetic fibers to regain their shape while maintaining a luxurious, smooth texture. With a 38% purity and weak cationic ionicity, it provides excellent affinity for fibers without compromising material stability. This pale yellow transparent liquid is optimized for high-efficiency industrial use, offering a stable structure that is both eco-friendly and highly effective for yarn and fabric treatments.

• Appearance: Pale yellow and transparent

• Composition: Ternary Copolymer

• Purity: 38%

• pH Value: 6-7

• Ionicity: Weak cationic

• Package: 120kg, 200kg

• Ternary Copolymer (Terpolymer) Structure: Provides a stable structure that ensures consistent, long-lasting performance throughout the textile life cycle.

• Good Resilience and Rebound: Specifically formulated to offer fluffy rebound, helping polyester fabrics recover their original shape after stretching.

• Soft and Smooth Finish: Significantly reduces surface friction to deliver a premium, soft and smooth tactile experience.

• Stable pH Value (6~7): Features a neutral-to-slightly-acidic pH value of 6~7, ensuring compatibility with common textile processing environments.

• Weak Cationic Ionicity: The weak cationic nature enables efficient exhaustion onto negatively charged polyester fibers for uniform coating. 

• Polyester Elastic Finishing: Primarily used to treat polyester elastic fabrics to improve their stretch recovery and surface softness.

• Yarn Softening: Its balanced formula is also suitable for yarns, providing essential lubrication and volume during the spinning or knitting process.

• Fluffy Rebound Treatment: Ideal for garments requiring a "bouncy" or fluffy rebound effect, such as high-loft knitwear or sportswear.

• Industrial Fabric Processing: A reliable factory direct sale choice for large-scale production lines focusing on synthetic fiber finishing.

• Green Environmental Finishing: Part of the "Green" product line, it is suitable for manufacturers seeking high-performance stable structure agents that meet modern standards.
