Hydroperm SRHA<br />
Soil Release / Hydrophilic / Antistatic<br />
a) Main features<br />
Hydroperm SRHA liq is a soil release and<br />
hydrophilizing agent for woven and knitted synthetic<br />
fi ber textiles, especially those made from polyester<br />
fi bers and polyester/cellulosic fi ber blends. This<br />
auxiliary overcomes the well known uncomfort of<br />
synthetic fi bers.<br />
b) Features<br />
Improves durable moisture absorbency of<br />
polyester fi bers.<br />
Imparts soil and stain release properties.<br />
Minimizes static build-up and adds comfort to<br />
the garments.<br />
Prevents soil re-deposition.<br />
Inhibits greying of polyester-containing fabrics<br />
during laundering.<br />
Saves time and money because it can be added<br />
directly to the dye-bath during high-temperature<br />
dyeing.<br />
Acts as a lubricant in the dyeing process,<br />
improving piece-to-piece consistency.<br />
c) Durable hydrophilic properties<br />
1. unfi nished (PES fi ber naturally hydrophobic).<br />
2. 5% (owf) Hydroperm SRHA liq.<br />
3. 5% (owf) Hydroperm SRHA liq / 1x 40 °C.<br />
4. 5% (owf) Hydroperm SRHA liq / 5x 40 °C.<br />
5. 5% (owf) Hydroperm SRHA liq / 10x 40 °C.<br />
After this Hydroperm SRHA treatment the<br />
uncomfortable PES is transformed into a hydrophilic,<br />
comfortable PES fi ber.<br />
