Hydrophilic Silicone Softener

POWSIL™-59257 is a polyether silicone terpolymer that ensures consistent hydrophilicity across all textile fibers and fabrics. It provides a soft, smooth hand feel, remains stable without causing oil spots in finishing processes, and offers fast, consistent water absorption.

POWSIL™-59257

Introduction


POWSIL™-59257 is a new polyether silicone terpolymer which can impart a consistent hydrophilicity for all types of textile fibers or fabrics compared to other silicone softeners.


POWSIL™-59257 provides a soft and smooth feel to various fabrics. It is very stable and will not generate oil spots in the general textile finishing process.


Benefits


  • Provides fast & consistent water absorption on various fibers & fabric;


  • Imparts soft & smooth hand feel;


  • Non yellowing as epoxy modified;


  • Additional emulsifiers free but self-dispersed in water and alcohols;


  • Can be diluted with water to any grade without additional emulsifies;


  • Very stable & non oil-spots if used in general textile finish process;


  • Excellent affinity with all types of textile;


  • Excellent fiber elasticity and shape recovery;


  • Durable softness to laundering if catalyst is used;



  • Doesn’t interfere with the oil release properties of fabrics treated with fluorocarbon;


  • Redyeable & over dyeable.

Application


POWSIL™-59257 can be directly used as received or can be pre-diluted with water only. Followings are guide formulations for different silicone active content emulsions that can be generally applied in textile finish process.


  • Potential Applications:

1. Fast hydrophilic property to all kind of fabrics or fibers, or some nonwoven;

2. Hydrophilic enhancer to be co-applied with other softeners, such as fatty acid flakes, amino-silicone;

3. Co-emulsifiers


  • Micro-emulsion for 23.0% silicone actives

  • 2. Procedure

1) Charge water at first and then start to stir;

2) Slowly add POWSIL™-59257 while continuously stirring;

3) Clear micro-emulsion should be obtained at end of this procedure;

4) Filter before packing, if necessary.



The diluted POWSIL™-59257 can be applied to fabric. The optimum treatments are dependent on the required softness of the fabric and yarn after dyeing and finishing.
