v  Provides voluminous, soft and smooth hand feel

v  Virtually no fabric yellowing

v  Excellent chemical stability,can resist high temperature, salt, PH and high shear

v  Excellent fiber elasticity and shape recovery

v  Redyeable

v  Lower dosage

Technical Index

Application

As a textile auxiliary agent, RUISOFT HBS can be used for all kinds of fabrics including natural fabrics or synthetic fabrics, especially for terrycloth. It’s a hydrophilic textile softener consisting of revolutionary silicone molecules.

RUISOFT HBS should be emulsified before applying in textile finish process. It is easier to be emulsified than other traditional silicone oil. Normal equipment and emulsifier can meet the requirement.

For textile finish process, RUISOFT HBS can be applied by padding and impregnation finishing. Formulations based on RUISOFT HBS have good pH-stability that extend well into the alkaline range, and offer good shear resistance. When in use, there absolutely not exist the phenomenon of sticky roller, sticky cylinders, floating oil, emulsion breaking.

Formulation(20%)

l  RUISOFT HBS                                        20.0g

l  Emulsifier AEO-6                                       3.2g

l  Emulsifier TO9                                         3.2g  

l  Butylcarbitol                                           1.6g

l  Acetic acid(33%)                                        0.4g

l  Water                                                71.6g

AEO-6: lauryl alcohol ethoxylates with 6EO

TO9: tridecyl alcohol ethoxylates with 9EO

Emulsification process

1. Add RUISOFT HBS , emulsifier and butylcarbitol in the container, start to stir for 10 minutes until fully homogeneous

2. Premix acetic acid and water

3. Slowly add 24g acidic water while continuously stirring the mixture for 20mins. 

4. Slowly add 24g acidic water while continuously stirring the mixture for 20mins.

5. Slowly add the rest acidic water while continuously stirring the mixture for 20mins.

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

7. Filter before packing, if necessary

Usage

Performance comparison

The products are subjected to the form of micro-emulsion, following the proportion of oil around 20% in the emulsion. The samples are applied in concentrations of 25 grams per liter on cotton.

Salt resistant stability

To realize the salt resistant stability test we use 10g/l Na2SO4 and 20g/l RUISOFT HBS in 200ml bath. The following pictures are the results of the test.

Alkali resistant stability

To realize the salt resistant stability test we use 1.2g/l NaOH (pH=12) and 20g/l RUISOFT HBS in 200ml bath. The following pictures are the results of the test.

Shear resistant stability

To realize the shear resistant stability test we use 0.5g/l Na2CO3, 1g/l Na2SO4, 0.1g/l reactive dye and 50g/l RUISOFT HBS in 200ml bath. The stirring speed is 2000r/min,and the temperature is 50℃. The following pictures are the results of the test.

Packing

RUISOFT HBS is available in 200kg plastic drums or other packing on request.
