Abstract
A polyester plain weave fabric construction wherein said fabric has a basis weight of between 150 to 300 g/mwith tongue tear strength equal to or better than nylon fabrics of the same construction and weight. The present invention relates to both coated and uncoated polyester filament woven fabric. The uncoated fabric is useful for industrial purposes wherein the fabric has a warp tongue tear resistance of at least 0.75 N/g/m, when the fabric basis weight is between 150 to 300 g/mThe preferred uncoated polyester filament yarn has a linear density of between about 200 to about 800 dtex, a tenacity of at least 65 cN/tex, a tensile index of at least 350. The fabrics can be coated with chloroprene, neoprene, polyurethane, silicone or other organic coatings to reduce air permeability. The fabric of the present invention may also be constructed with the warp and/or filling yarn having an aspect ratio between 1.2 and 6.
