Product Description

RUISOFT KHS is a linear block silicone co-polymer, with quat, polyether functional groups and other traditional chemical entities. RUISOFT KHS delivers a hydrophilic, soft, silk and voluminous hand to all kinds of fabrics,but is particular suitable for natural fiber. After the treatment of RUISOFT KHS, the fabric still maintain their original which amount is less than other traditional softener.

Features and Advantages

● Provides soft, silk and voluminous hand feel

● Good hydrophilicity

● Increases the hydrophilicity of synthetic fiber 

● Provides stretch recovery and increases elasticity

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

● Easy to emulsify

● Redyeable 

● Causes little yellowing of white or light color fabrics

Application

RUISOFT KHS can be used for all kinds of fabrics. But the best performance will be achieved when applying to following fibers, such as cotton, cotton blends, wool, wool blends, viscose, rayon, acetate and polyester woven.

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

RUISOFT KHS can be applied by padding and impregnation finishing. The emulsion is extreme stable in a wide PH range, high temperature or high concentrations of salts. Also, it will not stick to rollers. As a result, RUISOFT KHS can be used in special conditions. 

Because of its cationic structure, RUISOFT KHS has limited compatibility with anionic auxiliaries. Compatibility tests should be carried out before it is used together with other chemicals.

Formulation (20% emulsion) 

◆ RUISOFT KHS                             20g

◆ Basf TO-6                                   5g

◆ Acetic acid                                  0.3g

◆ Water                                         74.7 g 

TO-6 : Tridecyl Alcohol 6EO ethoxylated (CAS # 24938-91-8)

Process

1. Add RUISOFT KHS and emulsifier in the container, start to stir for 5-10 minutes. 

2. Premix acetic acid and water.

3. Slowly add the acidic water while continuously stirring mixture in the container.  Stop adding the acidic water occasionally to ensure the water is well taken into the grease.

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

Salt resistant stability

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

Result

After 3 hours of heating, RUISOFT KHS is still transparent

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 softener in 200ml bath. The stirring speed is 2000r/min,and the temperature is 50℃. The following pictures are the results of the test.
