Technical advantages
– Processing on common finishing
lines.
– Suitable for cotton and selected
natural and regenerated cellulosic
fibres as well as blends with
synthetics.
– Very low impact on fabric strength
allowing wider range of fabric
selection and end-uses.
– Safer processing due to absence of
formaldehyde emissions.
– No oily deposit formation in stenter
compartments, as easily removable
deposits are formed.
– No ‘bad smell’ formation as
observed with established reactive
phosphonate chemistry.

Novel technology for protective apparel
Comparison Pekoflam ® ECO/SYN – Pekoflam ® DPN –
Pekoflam ® DCB
FR test according to EN15025 on a royal blue 290 gsm
cotton protective wear fabric:
– DPN treated fabric fails test after 100 domestic
laundries, as flames reach upper mark within
20 seconds, and material is completely charred.
Comparison material treated with our new
technology does not even ignite during contact with
the gas burner flame, comparable to the ammonia
cured fabric treated with DCB.

Benefits of novel finishing
technology
Clariant’s concept for sustainable
protection:
– SUSTAINABILITY: Suitable for
renewable fiber materials.
– PROTECTION: Safe handling and
low environmental footprint.
– ECOLOGY: No additional
chemical consumption in rinsing
and no fabric neutralization
needed.
– FLEXIBILITY: High strength
retention enlarges material selection
pool.
– ECONOMY: Cost competitive to
established concepts.
