Product Description

Super Soft Hydrophilic Silicone Oil RUISOFT RJ-8016A is a linear block silicone copolymer with quat, polyether functional groups and other traditional chemical entities. RUISOFT RJ-8016A delivers a hydrophilic, soft, voluminous and smooth hand to natural fiber. Its outstanding emulsion stability overcomes poor stability and hydrophobicity of traditional amino silicone oil. The high performance-price ratio allows to reduce the cost of use greatly.

Features and Advantages

 v Provides soft, voluminous and silk hand feel

 v Does not alter the hydrophilic nature of cotton and cotton blends

 v No yellowing change, nearly no effect to color light

 v Excellent chemical stability,can resist high temperature, salt, PH and high shear, can be used in jet overflow machine

 v Good affinity to fabrics

 v Easy to emulsify

 v Durable softness

 v High performance-price ratio

Application

RUISOFT RJ-8016A can be used for all kinds of fabrics. But the best performance will be achieved when applying to natural knits and woven fibers, such as cotton, cotton blends, wool, wool blends, viscose, rayon acetate and so on.

RUISOFT RJ-8016A 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.

For textile finish process, RUISOFT RJ-8016A can be applied by padding and impregnation finishing. The emulsion of RJ-8016A 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, RJ-8016A can be used in special conditions.

Because of its cationic structure, RUISOFT RJ-8016A has limited compatibility with anionic auxiliaries. Compatibility tests should be carried out before it is used together with other chemicals.

Formulation

  •  RUISOFT RJ-8016A                                                      20g

  •  Emulsifier(BASF XL40:BASF XL90=4:6.)                5g                                         

  •  Acetic acid                                                                     0.5g 

  •  Water                                                                             74.5g

Attention: if you don’t have Basf XL series emulsifier, we recommend isotridecyl alcohol ethoxylates with 5EO and 7EO, the ratio of 5EO and 7EO is 1:1 or 3:2.

Process

1. Add RJ-8016A and Emulsifier in the container, and start to stir for 10 minutes.

2. Mix Acetic acid together with water

3. Slowly add acid water into the mixture for several times while stirring 

4. Adjust the PH Value to 6 around.

5. Filter into the container
