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 method of enhancing crop growth, comprising:
- covering a crop planting site comprising one or more crops planted thereon with a fabric having a spunbond layer comprising filaments including a filler;
- wherein the fabric comprises a basis weight of least about 12 grams-per-meter-squared (gsm);
- wherein (i) an average transmittance value within a photosynthetic active radiation (PAR) across wavelengths 400 nm to 700 nm of the spunbond layer comprises 37% or less, and (ii) an infrared radiation (IR)-transmittance value across wavelengths 7000 nm to 14000 nm of the fabric comprises from about 10% to about 70%.
A method of enhancing crop growth, comprising:
- (i) covering a crop planting site comprising one or more crops planted thereon with a fabric having a spunbond layer comprising filaments including a filler;
- wherein (i) an average transmittance value within a photosynthetic active radiation (PAR) across wavelengths 400 nm to 700 nm of the spunbond layer comprises 37% or less, and (ii) an infrared radiation (IR)-transmittance value across wavelengths 7000 nm to 14000 nm of the fabric comprises from about 10% to about 70%;
- and
- (ii) maintaining the fabric directly or indirectly over the crop planting site for a total time duration of from about 100 to about 4400 hours.
