POWERSOFT UP 70 LV is a nonionic micro emulsion concentrate of a reactive modified aminofunctional polydimethylsiloxane for use in non-yellowing and hydrophilic textile finishing.
POWERSOFT UP 70 LV is particularly suitable in softener formulations for the impregnation of fibers and textiles.
POWERSOFT UP 70 LV imparts a soft, drapable and elastic touch to woven and knitted fabrics.
In comparison to usual silicone-based, medium hydrophilic softeners POWERSOFT UP 70 LV shows excellent stability in the presence of salt and resins, even under high shearing conditions.
POWERSOFT UP 70 LV is readily dilutable with cold water to any desired concentration. Dilutions of the product are resistant to alkaline conditions up to pH 10.
Furthermore POWERSOFT UP 70 LVcan be used in direct combination with many optical brighteners due to its good 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 70 LV does not turn cotton and other hydrophilic substrates hydrophobic.
Cotton treated with POWERSOFT UP 70 LV shows good hydrophilicity which offers advantages if overdyeing of the fabric is required.
When applied under normal conditions as part of a softener formulation, POWERSOFT UP 70 LV has no effect on the whiteness degree.
Compared to polyether containing hydrophilic softeners POWERSOFT UP 70 LV provides a considerably better wash-durability of the soft-hand properties.
POWERSOFT UP 70 LV does not contain SVHC relevant impurities of more than 0.1% each, e.g. cyclics D4, D5 or D6.
Application:
The application of POWERSOFT UP 70 LV on textiles can be done either by padding or exhaustion method.
Emulsions prepared out of POWERSOFT UP 70 LV are diluted to the optimum concentration for the specific fabric.
POWERSOFT UP 70 LV can be applied either alone or together with resins and other finishing agents.
POWERSOFT UP 70 LV may also be combined with different organic, nonionic and cationic fabric softeners.
The compatible ratio of POWERSOFT UP 70 LV and organic softener must be tested prior to use on a case-by-case basis.
Processing:
Typical recipe for woven and knitted materials of cotton and synthetic fibres:
0.5 ml/l acetic acid 60 %
10-20 g/l POWERSOFT UP 70 LV
Padding, liquor pick-up about 70 %
Drying at 150 °C / 3 min.
