Hydrophilic Silicone Softener

Technical Data

Application

• Since POWSIL-59100 silicone fabric softener is a silicone oil that cannot be applied directly on fabrics. It should be emulsified before applying in the textile finish process. However, emulsifying it is much easier than emulsifying other silicone fluids conventionally used in the application of textile softener. POWSIL-59100 can be readily emulsified using normal equipment and procedure.

• Micro-emulsion for 24.0% of POWSIL-59100

• Formulation

  Composition    % wt

  POWSIL-59100   24.0

  TDE-6 or AEO-6*   6.0

  Acetic Acid    0.3

  Water     69.7

  
  

• Preservative if required ~

  - TDE-6: Tridecyl Alcohol 6EO ethoxylated

  - AEO-6: Fatty alcohol ethoxylated with 6 EO

  
  

• Procedures:

  Stir POWSIL-59100 content to make it homogeneous;

   Charge POWSIL-59100 and TDE-6 or AEO-6 into a mixer, and then stir the contents at moderate speed for about 10 min till fully homogeneous;

  Premix acetic acid and water;

  Slowly add the acidic water while continuously stirring POWSIL-59100 and TDE-6 or AEO-6 in the mixer. Stop charging the acidic water occasionally to ensure the water is well absorbed into the grease;

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

  Filter before packing, if necessary.

•  Procedure

  Stir POWSIL-59100 content to make it homogeneous;

  Charge POWSIL-59100 and TDE-6 or AEO-6, TDE-12 & butylcarbitol into a mixer, and then stir the contents at moderate speed for about 10 min till fully homogeneous;

  Premix acetic acid and water;

  Slowly add the acidic water while continuously stirring the above content at moderate speed;

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

  Filter above emulsion before packing, if necessary.

• The Example of Application of 24.0% POWSIL-59100 Microemulsion:

  24.0% of POWSIL-59100 can be used as received or pre-diluted with water before applying.

  Optimum treatments are dependent on the required softness of the fabric and yarn after dyeing and finishing.
