Garment prepared from fluoropolymer staple yarn

A garment for readily shedding a molten metal splash comprising,

• a single layer of fabric prepared from a single layer of woven, spun fluoropolymer staple yarn,
• wherein the garment excludes an inner heat resistant fabric layer adapted and arranged for preventing the transmission of heat through the garment,
• wherein the single layer of fabric has a weight in the range of about 8.0 ounces per square yard to about 11.56 ounces per square yard, and
• wherein the single layer of fabric has at least one of a thickness of about 0.033 inch and a thread count in the range of about 48 by about 48 threads per square inch to about 56 by about 56 threads per square inch.

• wherein the single layer of fabric has a weight in the range of about 8.0 ounces per square yard to about 11.56 ounces per square yard, and
• wherein the single layer of fabric exhibits a maximum temperature rise in the range from 7.1° C. to 14.6° C. when subjected to the molten metal splash in accordance with ASTM standard F955-03.

A method of manufacturing a garment that resists adherence thereto by a molten metal splash comprising,

• spinning a yarn from polytetrafluoroethylene staple fibers, wherein the yarn includes about 15% to about 50% by weight of polyvinyl alcohol staple fibers,
• weaving the yarn,
• producing a woven fabric from the yarn, the woven fabric including a single layer of the woven yarn,
• fabricating the garment from the fabric,
• excluding from the garment a heat resistant fabric layer that is in addition to the woven fabric, and
• removing essentially all of the polyvinyl alcohol staple fibers from the fabric.
