TRISCOUR JET CONC
100% active detergent developed especially
to provide the following properties:

Excellent degree of whiteness
 Outstanding hydrophilicity and very good absorbancy
 Low foam product suitable for all kinds of machines
 Stable to high pH and electrolytes
 Very efficient for cleaning cotton/elastane blends
 Suitable for PDF and Full white

This demonstrates that the speed of wetting of 100% bleached cotton with Triscour JET CONC is faster than
the competition
The Draves Test:
100% cotton yarn is bleached with the products to be evaluated and then dried. The yarn is attached to a
weight by the use of thread and then dropped into a cylinder filled with water. From the time the weight is at
the bottom of the cylinder to the time the tread attached to the yarn and the weight sags is recorded as the
wetting speed.
TRIASSIST DSA
 Removes residual alkali from bleaching
 Core neutralisation of the fabric
 Excellent dispersing properties and prevent
deposits on fabric and machinery
 Good binding properties with Fe, Ca and Mg
 No formation of undesired salts or buffers during
neutralisation
TRIMINOX GH
 Works over a very broad range of pH from 3 to 10
 Efficient in a wide temperature spectrum up to 65C
