POWERSOFT® CF 20

• POWERSOFT® CF 20 is particularly suitable as a softener for the impregnation of fibers and textiles. POWERSOFT® CF 20 imparts a very soft, smooth and elastic hand to woven and knitted fabrics. It improves the wash-and-wear properties and the crease recovery angle, sewability and tear strength and reduces abrasion loss.
• The effects are fast to washing and dry cleaning. POWERSOFT® CF 20 has little effect on the degree of white when usual application conditions are adhered to. As a rule, no adverse effect on the shade or color fastness properties of colored goods is observed.

Processing

• POWERSOFT® CF 20 gives permanent effects without the addition of a catalyst. Provided no resins are used, specific curing conditions need not be adhered to. POWERSOFT® CF 20 can be applied by padding but not by exhaust method in a jet dyeing machine. As with all products containing silicone, the finishing liquors should not be subjected to high shear, as this might cause instability. High loadings in wet-on-wet applications can cause pad roll build up.
• Special care should be taken to make sure rolls are cleaned periodically. 200-300 g/l of POWERSOFT® CF 20 are recommended for the pad method to achieve the elastic effect. Less can be used if only softening is needed. The pH of the liquor should not exceed pH 6. It may need to be adjusted with acetic acid.
• POWERSOFT® CF 20 can be applied both alone or together with resins and other finishing agents. If POWERSOFT® CF 20 is used together with cross-linking agents and other additives, it should be added, in dilute form, after all the other products. (This applies generally to the processing of all polysiloxanes). Higher crease recovery angles and lower abrasion values can be obtained in resin finishing by using POWERSOFT® CF 20.

Typical Formulation:

• 50-300 g/l POWERSOFT® CF 20
• Pad, liquor pick-up about 75%
• Dry at 120-150°C

POWERSOFT CF 20 imparts an excellent soft hand on cotton and polycotton substrates. POWERSOFT CF 20 is medium yellowing and imparts elastomeric properties to fabrics and knit ware. Stretch recovery is greatly improved. Because of the crosslinking nature of the product durability is much better than standard amino softeners.
