Abstract
Fluid impermeable, protective clothing is usually impermeable in both directions, and thus sweat is unable to evaporate from the skin or from inner clothing. A buildup of moisture is uncomfortable and, if prolonged, can cause pain and injury. A simple solution to the problem is to insert a two-layer liner in the impermeable clothing which will absorb the sweat. The liner includes an inner layer of vapor permeable, liquid impermeable material such as microporous Teflon (trademark) film, microporous polyurethane film or a hydrophilic polymer coating, and an outer layer of a material highly absorptive of both water vapor and liquid.
Claims4
A laminated clothing liner comprising an inner layer permeable to vapour and impermeable to liquid;
- and an outer layer highly absorptive to vapour and liquid, whereby the liner can absorb sweat while isolating the skin or inner clothing from absorbed moisture, said outer layer being selected from the group consisting of a needle-punched, nonwoven blend of a superabsorbent fiber and polyester, and a thermal bonded, nonwoven blend of a superabsorbent fiber and a thermo-bonding bicomponent of polypropylene.
