POWERSOFT® UP 68
POWERSOFT® UP 68 is a nonionic micro emulsion concentrate of a reactive modified aminofunctional polydimethylsiloxane for use in non-yellowing and medium hydrophilic textile finishing.
POWERSOFT® UP 68 is particularly suitable in softener formulations for the impregnation of fibers and textiles. POWERSOFT® UP 68 imparts a soft, drapable and elastic touch to woven and knitted fabrics.
In comparison to usual silicone-based, medium hydrophilic softeners POWERSOFT® UP 68 shows excellent stability in the presence of salt and resins even under high shearing conditions.
POWERSOFT® UP 68 is readily dilutable with cold water to any desired concentration. Dilutions of the product are extremely resistant to high alkaline conditions up to pH 11.
Furthermore POWERSOFT® UP 68 can be used in direct combination with many optical brighteners due to its high compatibility with such compounds. However, the compatibility should be tested on a case-by-case basis.
In contrast to many conventional silicone softeners, POWERSOFT® UP 68 does not turn cotton and other hydrophilic substrates completely hydrophobic. Cotton treated with POWERSOFT® UP 68 shows medium hydrophilicity which offers advantages if overdyeing of the fabric is required.
When applied under normal conditions as part of a softener formulation, POWERSOFT® UP 68 has no effect on the whiteness degree.
Specific features of POWERSOFT® UP 68
- Dilutable with water
- Excellent pH stability
- Good heat stability
Application of POWERSOFT® UP 68 on textiles can be done either by padding or exhaustion method. Emulsions prepared of POWERSOFT® UP 68 are diluted to the optimum concentration for the specific fabric.
POWERSOFT® UP 68 can be applied either alone or together with resins and other finishing agents.
POWERSOFT® UP 68 may also be combined with different organic, nonionic and cationic fabric softeners. The compatible ratio of POWERSOFT® UP 68 and organic softener must be tested prior to use on a case-by-case basis.
