Textile Testing Equipment

The intelligent barrier film material can make the surface of biochemical personal protective equipment have self-sensing ("sensor" function) of poisonous and harmful substances, self-response ("actuator" function), self-adapting ability, ensuring the protection performance and adjusting breathability, moisture permeability self-disinfection or self-cleaning according to the external environment. This can greatly improve the protective performance and comfort of biochemical personal protective equipment. 

The intelligent materials which can respond to chemical or biological stimuli (including chemicals, PH, ionic concentration, reaction heat (Checking radiant-heat protective performance tester to know more about heat resistance), moisture, surface tension, function of bio-surface, etc.) includes conductive polymers, Chromium materials, active adsorbents and deformation materials. Among these materials, the conductive polymer is a promising biochemical intelligent protective sensor materials, such as polymer doped polypyrrole, polythiophene and polyaniline (PANI) can be used as a sensor to detect volatile and liquid chemicals.

The shape memory polymer has the ability to maintain the temporary shape and can recover the initial shape when subjected to appropriate external stimuli. The shape memory polymer has the advantages of low density, large amount of recoverable deformation, easy forming, and adjustable shape temperature. It has wide application to work as “actuator” self-reactive barrier film. The shape memory polyurethane can improve the wearing comfort of fabrics by using its thermal activation properties can play low temperature (<Tg) low permeability of the warm and high temperature (> Tg) high permeability of the heat dissipation.

At present, the commercial shape memory polyurethane materials include shape memory polyurethane heat-sensitive breathable films developed by SMP Technologies, shape memory polyurethane-based film materials developed by Ahlstrom of Finland (temperature-sensitive , Breathable overall film sandwiched between two layers of microfiber spunbond polypropylene non-woven fabric made) and so on.
