Hydrophilic Silicone Softener

Introduction

POWSIL™-50257 is a polyether silicone terpolymer that provides consistent hydrophilicity to all types of textile fibers and fabrics. It imparts a soft, slick hand feel while remaining stable during the textile finishing process without causing oil spots.

Benefits

• Non yellowing as epoxy modified;

• Imparts soft & smooth hand feel;

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

• No extra emulsifiers included 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 soil release properties of fabrics treated with fluorocarbon;

• Redyeable & over dyeable.

Typical Physical Properties

Applications

• POWSIL™-50257 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.

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

Formulation:

Procedures:

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

2. Slowly add POWSIL™-50257 while continuously stirring;.

3. Clear micro-emulsion will be obtained at end of this procedure;

4. Filter before packing, if necessary.

The diluted POWSIL™-50257 can be applied to fabric. The optimum treatments are dependent on the required softness of the fabric and yarn after dyeing and finishing.

Pad-dry-cure process

Exhaustion process

Garment washing process

Stripping:

POWSIL™-50257 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.
