Claims20
A launderable composite fabric material comprising:
- a shell fiber layer comprising nylon at about 58 wt %, polyester, and elastane;
- and
- a spun fiber membrane coupled to the shell fiber layer;
- wherein the composite fabric material exhibits a low range hydrostatic water resistance of between 5,000 millimeters (mm) and 10,000 mm as measured using American Association of Textile Chemists and Colorists (AATCC) 127;
- wherein the composite fabric material exhibits an air permeability of between 0.25 cubic feet per minute (cfm) and 0.75 cfm as measured using American Society for Testing and Materials (ASTM) D737;
- wherein the composite fabric material exhibits a moisture vapor transmission rate (MVTR) of between 30 kilogram per square meter per 24 hour (kg/sqm/24 hr) and 45 kg/sqm/24 hr as measured using Japanese Industry Standards (JIS) L1099-B1;
- and
- wherein an overall fabric weight of the composite fabric material is about 102 grams per square meter (gsm).
