Product Description

RUISOFT RJ-8016C is a linear block silicone copolymer with quat, polyether functional groups and other traditional chemical entities. RUISOFT RJ-8016C delivers a soft, smooth and voluminous hand to natural fiber. It provides excellent hydrophilicity which can be compared with traditional polyether silicone oil. So RUISOFT RJ-8016C can improve wearing comfort.


Features and Advantages

  •  Provides soft,smooth and voluminous hand feel

  •  Good hydrophilicity

  •  High shear resistance

  •  Excellent hand feel, can completely replace traditional amino silicone oil

  •  Good affinity to fabrics

  •  Easy to emulsify

  •  Durable softness

  •  Does not affect the color of dark fabrics

  •  High performance-price ratio

Application

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

 

RUISOFT RJ-8016C 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.

 

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


Formulation(20%)

  •  RUISOFT RJ-8016C                                                      20g

  •  Emulsifier(BASF XL40:BASF XL90=1:1)                   5g                                         

  •  Acetic acid                                                                   0.5g 

  •  Water                                                                          74.5g

 

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


Process

1. Add RUISOFT RJ-8016C 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

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 RJ-8016C in 200ml bath. The stirring speed is 2000r/min,and the temperature is 50℃. The following pictures are the results of the test.
