Multi-component comfortable cooling fabric and preparation method thereof

Abstract

The disclosure relates to a multi-component comfortable cooling fabric and a preparation method thereof. This fabric is formed by blending and spandex knitting several fibers with different properties, such as polyamide fibers with continuous cooling properties, regenerated cellulose fibers with high hygroscopicity, functional fibers with moisture-wicking properties and polyurethane fibers. The obtained cooling fabric is superior to its conventional counterparts on the market in terms of cooling value, cooling duration, moisture absorption rate, and moisture-wicking performance. Meanwhile, this cooling fabric has good air permeability and softness, which significantly improves the comfort experiences of the user's human body. In the test for contact continuous cooling property, the fabric reaches the indicator of Level 2 regarding the contact continuous cooling property.

         2 . The multi-component comfortable cooling fabric according to  claim 1 , wherein the characteristic thereof is the ratios of the fibers, wherein the functional fibers with moisture-wicking properties component accounts for 20% to 30%, the polyamide fibers with continuous cooling properties component accounts for greater than or equal to 50%, the regenerated cellulose fibers component accounts for 5%-35%, and the polyurethane fibers component accounts for about 10%-13%. 
     
     
         3 . The multi-component comfortable cooling fabric according to  claim 1 , wherein the fabric has a gram weight of 170-190 g/m 2 , the polyurethane fibers have a single fiber fineness of 30 D, other fibers have a single fiber fineness of 30-70 D and the fabric has a fabric width of 2.4 m to 2.9 m. 
     
     
         4 . The multi-component comfortable cooling fabric according to  claim 1 , wherein the polyamide fibers with continuous cooling properties are formed by adding cooling factors, nanoscale jade powders, into the polyamide fibers, and the fibers with continuous cooling properties have cross sections in an irregularly-shaped flat shape. 
     
     
         5 . The multi-component comfortable cooling fabric according to  claim 1 , wherein the functional fibers with moisture-wicking properties comprise modified polyamide fibers, or modified polyester fiber; wherein the functional fibers with moisture-wicking properties are specifically designed with cross-shaped sections to increase grooves and gaps on the fiber surfaces, to increase moisture migration and water absorption, and to accelerate water vapor diffusion. 
     
     
         6 . The multi-component comfortable cooling fabric according to  claim 1 , wherein the functional fibers with moisture-wicking properties are full dull fully drawn filament yarns, the polyamide fibers with continuous cooling properties are semi-dull drawing textured filament yarns, and viscose fibers comprise filaments or staple fibers. 
     
     
         7 .
