RUISOFT 8065M can be used for all types of fabrics and colors, including cotton, cotton blends, synthetics and other cellulose. But the best performance will be

achieved when applied to cotton and cotton blends. Remarkably, retain the hydrophilicity even after extreme cure conditions as well as on aging of treated fabrics.

RUISOFT 8065M should be easily emulsified with simple mixer. It is easier to be emulsified than other traditional silicone oil softener. Normal equipment and emulsifier can meet the requirement.

The emulsion of RUISOFT 8065M is extremely stable under high shear, wide PH range (3-12) and high temperature. As a result, RUISOFT 8065M can be applied onto fabrics by all types of finishing equipment including high speed padding, kiss roll, spray, exhaustion, etc.

1. Charge RUISOFT 8065M, emulsifier and butyl carbitol in the container, start to stir at 800~1,00rpm for 20 minutes until fully homogeneous.

2. Premix acetic acid and sodium acetate in water.

3. Slowly add the acidic water while continuously stirring mixture in the container. Avoid stirring too much air into the mixture.

4. Reduce mixing speed to 400~500rpm and continue to stir for 20 minutes.

5. Clear micro-emulsion should be obtained at end of this procedure
