Fabric with cool feeling function and related clothing items, manufacturing method and manufacturing systems

Abstract

A fabric with cool feeling function and related cloth clothing items and method and systems. The fabric comprising a first fabric layer and a second fabric layer and related method of making are disclosed, wherein the first fabric layer is formed by interweaving hygroscopic yarn materials, and the second fabric layer is formed by interweaving thermally conductive yarn materials; the first fabric layer and the second fabric layer are connected through knotting spots formed by interweaving the hygroscopic first fabric layer and the thermally conductive second fabric layer. A layered structure weaving method and resulting structure of the fabric results in an interaction between the hygroscopic yarn materials and the thermally conductive yarn materials which continuously produces cool feeling effects.
