TECGEN SELECT® OPF Blend Twill (5.5oz / 186gsm)

TECGEN® Select® OPF Blend Twill is an excellent FR/AR fabric, particularly valued for balancing high-level protective compliance with exceptional daily wearer comfort. The fabric offers advanced fibre material technology.

Inherent FR/AR Properties: The flame resistant capabilities are integrated into the fabric's core fibre chemistry, which is a specialised blend of FR Rayon (35%), Modacrylic (27%), OPF (21%), Aramid (15%) and Nylon (2%). This ensures the safety protection cannot be washed or worn out over time, maintaining long-term integrity.

OPF Technology: The fabric utilises Oxidized Polyacrylonitrile Fibres (OPF), the same high-tech precursor material used to manufacture carbon fibre structures for aerospace applications and high-performance race cars. 

Moisture Management: The blend delivers rapid moisture-wicking capabilities and an exceptionally high drying rate, drawing perspiration away from the skin to actively facilitate evaporative cooling.
