Abstract: The invention features a lining material for footwear. The material includes a non-woven felt including up to 80% by weight of grooved or multi-lobed cross section transport fibers and the remainder of thermally bondable fibers arranged to secure the transport fibers against abrasion and excessive mechanical stretch presented during incorporation of the lining material into a product during that product's manufacture.

Abstract: A wound dressing combining a graduated density felt 1 with an absorbent fiber layer 2 in order that the aggressive absorption of the absorbent layer 2 may be regulated to acceptable rates for wound dressing usage and to ensure potentially irritative alginate absorbent fibers are isolated from the wound site. The graduated density felt 1 acts as a regulating or gate layer for the absorbent fiber layer 2 and so limits the rate that exudate from a wound can pass to the absorbent fiber layer 2. Furthermore, the regulating layer 1 effectively spreads the exudate to give a conical transmission profile enhancing wound dressing performance.

Abstract: Non-woven fiber fabrics are described, suitable for use in self-supporting dust filter units having at least one passage (10) defined by wall portions (12) made from air permeable fiber fabric through which wall portions (12) air can pass a d be drawn off along the passage (10) but which prevent the passage therethrough of dust and/or other debris carried by the air. The non-woven fabrics are blends of high temperature resistant fibers. A preferred blend consists of 50% by weight polyimide fibers and 50% by weight aramid fibers, but may include glass fibers, polytetrafuoroethylene fibers, or others and may optionally include an amount of heat activated fibers having a relatively high melting point for example, polyphenylene sulphide fibers.
