| About
PR97™ Fabric PR97™ fabric is the result of five years intensive research and
development aimed at developing the next generation fabric for
protective clothing for use in the world's harshest working
environments. PR97™ has set new standards in terms of protection and
comfort.
Fabric Features
PR97™ is comfortable from new and laundering and wear enhance its
comfort. This fabric is far more user friendly than treated cotton,
which has a distinctly unappealing feel when new. The protective
properties of the fabric are built in to its construction and are
therefore permanent and cannot be laundered out.
The slightly higher initial costs of garments constructed from PR97™
are more than offset by extended lifespans attributable to the fact that
the material retains its safety features over its entire life. Garments
constructed from PR97™ are truly multi-functional and can be used from
smelter pot-rooms to maintenance areas to boardrooms.
Flame Retardant
PR97™ is inherently flame retardant. Unlike FRT cotton, where fire
retardancy can be removed with laundering, PR97™ is inherently flame
retardant and will retain its FRT properties for wash after wash.
PR97™ will not melt or stick to the skin. It will not ignite when
exposed to electrical arc or molten metals. PR97™ provides significantly
higher protection from first and second-degree burns (from molten metal
and cryolite splash) than any other product currently in service of
equal weight. The fabric will maintain this performance over its entire
life span.
Breathability
Heat stress is a problem often suffered by wearers of fire resistant
products. This problem is minimised with PR97™, which provides a unique
wicking effect that absorbs moisture immediately in order to aid the
evaporative cooling process. An additional benefit of PR97™'s inherent
flame retardancy is that the lack of any chemical treatment in its
construction maximises air circulation without affecting safety
performance.
Test Information
PR97™ has been subjected to extensive laboratory testing at Wronz
Developments in New Zealand. The testing addressed the assessment of the
fabric's resistance to molten metal splash.

and iron splash tests, click here.
PR97™ has also been subjected to extensive ASTM testing for
determination of Arc Thermal Performance (measurement of ATPV and
HAF), with high current laboratory testing conducted by Kinectrics Inc.,
Toronto, Ontario, Canada.

Care Instructions
Unlike treated cotton, PR97™ can be dry cleaned, thus providing
significant advantages in areas where heavy soiling are likely to occur.
Cleaning Instructions
PR97 fabrics and garments can be dry-cleaned and washed. The washing,
however, must be carried out at gentler conditions than used for cotton
goods.
Suggested washing instructions are given below:
- Reduce the duration of the washing and rinsing cycles to the
minimum for adequate soil removal. Do not rotate the load between
draining and filling for the next laundering stage. A suggestion is a
flush followed by one wash and two rinses.
- Use high dip levels during washing and rinsing.
- Use neutral pH (pH 6-8) non ionic detergent, do not use soap or
bleaches.
- Use low temperatures during washing preferably 40ºC with cold
water rinses. Tumble drying temperatures should be 60ºC-80ºC. It is
essential that the garments are not tumbled for long periods.
- A satisfactory washing technique which has been used is: -
- 2 minute cold flush
- 8 minute wash at 40ºC and low speed spin
- 2 minute cold rinse
- 2 minute 40ºC rinse
- 6 minute fast extract
- Tumble dry at 70ºC
If the garments are washed with care in a manner to that described
above they will have a long life.
