Cooling Material for Protective Garment

Abstract

A yarn having a plurality of filaments in which the filaments are made of a polymer having a moisture regain of 5 w/w % or less. The plurality of filaments is composed of individual filaments each having a linear density in a range of 1 to 3 denier, and the individual filaments have a multilobed cross-sectional shape. The yarn can be incorporated into fabrics, in particular for protective garments.

What is claimed is: 
     
         1 . A yarn, comprising:
 a plurality of filaments, the filaments comprising a polymer having a moisture regain of 5 w/w % or less;   wherein the plurality of filaments is comprised of individual filaments each having a linear density in a range of 1 to 3 denier; and   wherein the individual filaments comprise a multilobed cross-sectional shape.   
     
     
         2 . The yarn of  claim 1 , wherein the polymer comprises polyamide, polyester, or a blend of polyamide and polyester. 
     
     
         3 . The yarn of  claim 1 , wherein the multilobed cross-sectional shape is a star. 
     
     
         4 . The yarn of  claim 1 , wherein the yarn comprises a powder configured to enhance a thermal effusivity of the yarn. 
     
     
         5 . The yarn of  claim 4 , wherein the powder is a pyroxene mineral. 
     
     
         6 . The powder of  claim 5 , wherein the pyroxene mineral is jadeite. 
     
     
         7 . The yarn of  claim 1 , further comprising a core filament comprised of an elastic material, wherein the plurality of filaments form a sheath around the core filament. 
     
     
         8 . The yarn of  claim 7 , wherein the elastic material comprises elastane. 
     
     
         9 . The yarn of  claim 7 , wherein the core filament has a linear mass density in a range from 10 denier to 60 denier. 
     
     
         10 . The yarn of  claim 1 , wherein the plurality of filaments is from 50 to 150 filaments. 
     
     
         11 . A fabric comprising the yarn according to  claim 1 . 
     
     
         12 . A garment comprising the fabric of  claim 11 , the garment being selected from a group consisting of a gaiter, a sleeve, a balaclava, a t-shirt, a glove, a helmet liner, or a cooling towel. 
     
     
         13 . A cut-resistant fabric, comprising:
 a first yarn, the first yarn comprising the yarn according to  claim 1 , and   a cut-resistant yarn.   
     
     
         14 . The cut-resistant fabric of  claim 13 , wherein the polymer of the first yarn is polyamide and wherein the multilobed cross-sectional shape is a star. 
     
     
         15 . The cut-resistant fabric of  claim 13 , comprising a single jersey knit pattern. 
     
     
         16 . A glove comprising the cut-resistant fabric of  claim 13 . 
     
     
         17 . The glove of  claim 16 , comprising an ANSI/ISEA 105-2016 cut level of at least 2. 
     
     
         18 . The glove of  claim 16 , comprising a rating of at least level B according to EN 388:2016. 
     
     
         19 . A protective sleeve comprising the cut-resistant fabric of  claim 13 , the protective sleeve comprising an ANSI/ISEA 105-2016 cut level of at least 1. 
     
     
         20 . A protective sleeve comprising the cut-resistant fabric of  claim 13 , the protective sleeve comprising a rating of at least level A according to EN 388:2016.
