Insulating sheer fabric
Fabrics which allow for light transmission and provide thermal insulation are described. A fabric is formed from at least one yarn to form a continuous web of fabric. The continuous web is configured to allow between 20% and 65% of incident light to be transmitted through the fabric, and to reduce heat transfer through the fabric such that the fabric has an R value of at least 0.75 K·m 2 /W. The continuous web of fabric may be a woven fabric where the at least one yarn is woven to form the woven fabric.
1. A woven fabric comprising:
warp and filling yarns arranged in a weave pattern and having a density of 96.0 warp threads per inch and 72.7 filling threads per inch as measured according to ASTM D3775, a weight of 78.65 g/m 2 as measured according to ASTM standard D3776, and a light transmittance of 60.2% with a standard deviation of 0.29% as measured according to AATCC 203-2014,
wherein the warp and filling yarns are 75 denier polyester as measured according to ASTM D1059;
wherein the fabric has a thermal insulation R value of 1.08 K·m 2 /W; and
wherein the weave pattern has a mean pore size of 68.07 μm with a standard deviation of 45.98 μm.
2. The woven fabric of claim 1 , wherein the woven fabric has a first side and a second side, and the first side and second sides have substantially the same construction.
3. A woven fabric comprising:
warp and filling yarns arranged in a weave pattern and having a density of 96.0 warp threads per inch and 64 filling threads per inch as measured according to ASTM D3775, a weight of 112.82 g/m 2 as measured according to ASTM standard D3776, and a light transmittance of 23.72% with a standard deviation of 0.462% as measured according to AATCC 203-2014,
wherein the fabric has a thermal insulation R value of 0.901 K·m 2 /W;
wherein the warp yarns are 37.8 denier yarns as measured according to ASTM D1059 and the filling yarns are 346.9 denier yarns; and
wherein the weave pattern has a mean pore size of 69.32 μm with a standard deviation of 55.73 μm.
4. The woven fabric of claim 3 , wherein the woven fabric has a first side and a second side, and the first side and second sides have substantially the same construction.
