SM-370 is a specialized cationic silicone emulsion designed as a high-efficiency bulking and softening agent for polyester yarns. It provides a non-greasy, dry finish that significantly enhances the fluffiness and tactile quality of synthetic fibers without causing knotting.

• Appearance: Transparent liquid 

• Ionicity: 5-7

• pH Value: Weak cationic

• Package: 120kg, 200kg

• Endows polyester yarns with excellent bulkiness and softness.

• Can be diluted in high proportions, with good softness enhancement.

• The finished yarns are dry (not greasy), not easy to knot, and have good bulkiness.

• Has excellent safety in use.

• Bulk Finishing: Primarily used to impart superior bulkiness and a "full" hand feel to polyester yarns during the finishing stage.

• Softness Enhancement: Acts as a powerful softener that can be diluted in high proportions while maintaining its performance.

• Tangle Prevention: Ensures finished yarns remain dry and easy to process, preventing the common issue of fiber knotting.

• Thread Lubrication: Provides a smooth, non-greasy surface that improves the mechanical properties of yarns for knitting and weaving.

• Safety-Critical Processing: Formulated for high stability and excellent safety in industrial use, suitable for diverse textile manufacturing environments.
