Abstract
A fabric resistant to degradation of strength and elastomeric properties upon exposure to ultraviolet irradiation is provided. The fabric includes an elastomeric fiber component which makes up not less than 40 percent by weight of the fabric. This elastomeric fiber component exhibits a tensile strength of not less than about 8 pounds force and retains at least 80 percent of its tensile strength following accelerated exposure to ultraviolet irradiation.
Claims17
A textile fabric formed from synthetic yarns and exhibiting resistance to strength degradation due to ultraviolet irradiation, said fabric comprising:
- a plurality of elastomeric synthetic yarns running in a first direction interwoven with a plurality of synthetic yarns running in a second direction substantially transverse to said first direction, wherein said elastomeric synthetic yarns running in said first direction comprise not less than about 40 percent by weight of said textile fabric;
- are characterized by an elongation at break of not less than about 50 percent;
- and retain not less than about 80 percent of their tensile strength upon accelerated exposure to 488 kilojoules of ultraviolet irradiation.
