Hydrophilic Silicone Softener

Introduction

POWSIL™-59258 is a new epoxy and polyether silicone copolymer that ensures consistent hydrophilicity across all textile fibers and fabrics. It imparts a soft, smooth feel and remains stable during the textile finishing process, without causing oil spots.

Benefits

• Provides instant & 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 ordinary 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.

Typical Physical Properties

Application

POWSIL™-59258 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 commonly 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 30.0% silicone actives

• 1. Formulation

• 2. Procedure

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

2) Slowly add POWSIL™-59258 while continuously stirring;

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

4) Filter before packing, if necessary.

The diluted POWSIL™-59258 can be applied to fabric. The optimum treatments are dependent on the required softness of the fabric and yarn after dyeing and finishing.

• 1. Pad-dry-cure process

• 2. Exhaustion process

• 3. Garment washing process

Stripping:

POWSIL™-59258 can be stripped off fabric. The stripping formulation is as follows:

Add water and NaOH onto fabric tank and then heat to 100 ºC for 60 min. Then rinse fabric with acidic water and water.
