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.
Claims22
A two-sided absorbing and cooling textile comprising:
- an absorbent side formed by two separate yarns comprising a first yarn and a second yarn,
- wherein the first yarn and the second yarn are located on separate but adjacent knitting bars during construction of the two-sided absorbing and cooling textile, and
- wherein a pile height of the absorbent side is greater than 0.2 millimeter for absorbing moisture from a skin surface;
- and
- a cooling side formed by four separate yarns comprising the first yarn, the second yarn, an evaporative cooling yarn, and an elastomeric yarn,
- wherein the cooling side is configured to transport the absorbed moisture from the absorbent side in order to expose the absorbed moisture to the cooling side for evaporation.
