Abstract

Disclosed herein is a warp knit spacer dual functional fabric construction that provides the ability to absorb sweat on one side and the ability to cool skin to below a current temperature whether wetted or dry on the other side. The knit uses four separate yarns which collectively work together to produce enhanced cooling. Knits can include warp knit spacer and circular knit spacer materials. Various finishing methods may also be employed to enhance the cooling power of the fabric.

Claims (85)

1. A two-sided absorbing and cooling textile comprising:
