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

3. 5% (owf) Hydroperm SRHA liq / 1x 40 °C.
4. 5% (owf) Hydroperm SRHA liq / 5x 40 °C.
5. 5% (owf) Hydroperm SRHA liq / 10x 40 °C.
After this Hydroperm SRHA treatment the
uncomfortable PES is transformed into a hydrophilic,
comfortable PES fi ber.
