Abstract
Abstract A fabric includes a first substrate layer; second substrate layer; the first and second substrate layers being at least translucent, being made from a non-woven fabric, and having a weight in the range between 0.25 ounces/yd. 2 and 8.0 ounces/yd. 2 ; a layer of filling material sandwiched between the first and second substrate layers, the layer of filling material including a plurality of substantially parallel, adjacent and spaced apart non-interwoven strands of yarn made of polypropylene, having a size in the range between 40 denier and 12,000 denier and running in a widthwise direction of the fabric between the first and second substrate layers; two opaque layers, one between the first substrate layer and the layer of filling material, and the other between the second substrate layer and the layer of filling material; and a stitching yarn having a size in the range between 40 denier and 1,000 denier and extending in a direction which is substantially transverse to the lengthwise direction, for securing together the first and second substrate layers, the two opaque layers and the layer of filling material.
