QuanFeng SF-320 - Polyester Smoothing Silicone Oil for Polyester Fabric

SF-320 is a high-performance ternary copolymerized organosilicon softener designed to provide polyester fabrics with deep "internal softness" and an exceptionally smooth hand feel. Its unique synthetic structure ensures a lightweight, premium finish that remains stable under extreme industrial conditions.
PRODUCTS DESCRIPTION

Silicone Based textile softener is a ternary copolymerized organosilicon finishing agent developed using advanced synthesis technology for textile processing. The ternary copolymer molecular structure allows the softener to deliver a refined smoothing and softening effect on polyester fabrics while maintaining stable performance under demanding finishing conditions. After treatment, fabrics obtain a lighter and smoother hand feel with improved internal softness and surface smoothness. Compared with conventional amino-modified organosilicon softeners, this formulation provides a cleaner and more balanced fabric touch, allowing polyester textiles to achieve a premium finishing effect. The treated fabrics maintain a smooth and comfortable hand feel while preserving fabric structure and appearance during subsequent processing.

key features

  • Deep Softness - Silicone based textile softener penetrates fiber structures and improves the internal softness of polyester fabrics, allowing the textile to maintain a smooth and flexible feel. Fabrics finished with silicone softening systems can achieve 20–35 percent reduction in yarn surface friction, which improves the internal softness perception and enhances the smooth hand feel of finished fabrics while maintaining structural stability.


  • Light Handle - The finishing system creates a thin and even silicone layer on the fabric surface, allowing polyester textiles to maintain a lightweight and thin tactile profile. Treated fabrics commonly show 15–25 percent reduction in bending rigidity, enabling materials to maintain a light and flexible drape while preventing the heavy or greasy feel sometimes associated with traditional softeners.


  • Heat Stable - Silicone based textile softener maintains stable performance during industrial textile finishing processes involving elevated temperatures. The formulation remains stable under typical drying and heat-setting temperatures ranging from 150 to 200 degrees Celsius, ensuring consistent finishing performance throughout continuous textile production operations.


  • Chemical Stable - The product maintains stable behavior in finishing baths exposed to common textile processing conditions. The formulation typically operates effectively within pH ranges between 6 and 7, allowing the working fluid to remain stable when exposed to acid or alkaline environments and helping maintain consistent finishing performance across production batches.


  • Shear Stable - Silicone based textile softener maintains emulsion stability under high mechanical agitation in industrial finishing equipment. During high-speed padding or circulation processes with shear rates above 3000 revolutions per minute, the emulsion remains stable without oil separation, allowing reliable distribution across the fabric surface during finishing operations.

application
  • Polyester Fabric - Silicone based textile softener can be applied during the final finishing stage of polyester fabric processing to improve the internal softness and tactile quality of the textile. The finishing agent is typically introduced into the final treatment bath and evenly distributed through padding or dipping processes. After drying and stabilization, polyester fabrics obtain a smoother internal hand feel and improved surface comfort suitable for garment production.


  • Light Apparel - In the production of lightweight polyester apparel fabrics, silicone based textile softener can be used to refine the tactile quality of finished textiles. The product is applied during the last finishing stage after dyeing and washing, followed by drying and heat setting. This finishing process allows garments to maintain a lighter and smoother hand feel while preserving the natural drape of polyester fabrics.


  • Industrial Finishing - Silicone based textile softener is suitable for continuous textile finishing lines where consistent production performance is required. The finishing agent can be added to padding systems and circulated evenly through the finishing bath. After drying and heat treatment, fabrics show improved softness and consistent surface quality suitable for large-scale textile manufacturing.


  • Dipping Process - Silicone based textile softener can be used in dipping finishing processes where fabrics are immersed in a finishing bath before drying. The chemical spreads evenly across the textile structure during immersion, allowing the finishing layer to form uniformly. After drying and stabilization, the treated fabrics obtain improved tactile smoothness and refined finishing quality.


  • Padding Process - Silicone based textile softener can also be applied in padding finishing operations commonly used in textile processing plants. The finishing solution is applied through padding rollers to ensure even distribution across the fabric surface before drying and heat setting. This process allows fabrics to achieve stable finishing quality and consistent softness during continuous production.
