Abstract
An improved ultraviolet (UV) blocking fabric that has an ultraviolet protection factor (UPF) rating of at least 49 in accordance with AATCC 183. The fabric does not require ultraviolet protecting coating(s) or finish(es) or such other treatment for achieving the desired ultraviolet protecting efficiency. Further, the fabric affords maintenance of the UPF rating even after the fabric has been subjected to several laundering cycles.
Claims20
An ultraviolet blocking fabric comprising:
- a warp yarn comprising a polyester yarn;
- and
- a weft yarn comprising an elastane yarn,
- wherein the fabric comprises a material composition of 87% to 91% of the polyester yarn and 9% to 13% of the elastane yarn by mass of the fabric,
- wherein the fabric has an ultraviolet protection factor (UPF) rating of at least 49 in accordance with AATCC 183-2010,
- wherein the fabric has a cover factor ranging from 65% to 85% after 40 laundering cycles in accordance with AATCC 135 2018,
- wherein the fabric has a fabric count of 43 wales/inch×72 courses/inch,
- wherein the fabric has an air permeability of 65 to 75 ft3/ft2·min, and
- wherein the fabric has a water vapor transmission of 750 to 800 g/sq·m per 24 hours.
