Abstract
Fabrics suitable for a wide variety of uses, including coverage of crops, crop planting sites, or both, are disclosed. The fabrics may comprise at least one spunbond layer comprising filaments including a filler. The at least one spunbond layer may comprise a basis weight of least about 12 grams-per-meter-squared and the at least one spunbond layer may comprise an average transmittance value within the photosynthetic active radiation (PAR) across wavelengths 400 nm to 700 nm comprising about 37% or less. Methods of enhancing crop growth are also disclosed.
Claims20
A fabric, comprising:
- a spunbond layer comprising filaments including a filler;
- and
- the fabric comprises a basis weight of least about 12 grams-per-meter-squared(gsm);
- wherein the average transmittance value within the photosynthetic active radiation (PAR) across wavelengths 400 nm to 700 nm of the spunbond layer comprises 37% or less.
A method of enhancing crop growth, comprising covering a crop planting site with a fabric having a spunbond layer comprising filaments including a filler;
- and the fabric comprises a basis weight of least about 12 grams-per-meter-squared(gsm);
- wherein the average transmittance value within the photosynthetic active radiation (PAR) across wavelengths 400 nm to 700 nm of the spunbond layer comprises 37% or less and the crop planting site comprising one or more crops planted thereon.
