An improved self-spreading trawl (13) includes first panels (56T, 56B) which when towed through a body of water (12) separate on opposite sides of the trawl's central axis (62). Portions of panels (56T, 56B) form portions of the trawl's mouth (26). The trawl (13) also includes second panels (56P, 56S) which separate on opposite sides of the central axis (62) from the sides occupied by the panels (56T, 56B). Portions of panels (56P, 56S) form portions of the trawl's mouth (26). Regions of panels (56P, 56S) generate more outwardly directed lift than corresponding regions of the panels (56T, 56B). When towed through the body of water (12): a) a distance separating the panels (56P, 56S) exceeds; b) a distance separating the panels (56T, 56B). Also a braided product strand which includes at least 3 plaits (76, 102), at least one (76) of which is larger than the others (102), advantageously exhibits less drag and vibration.

Auxetic fabric structures, of the sort which can be useful in conjunction with composite materials, and related methods of fabrication.

Cushioning net structures comprise random loops, such as three-dimensional random loops, bonded with one another, wherein the loops are formed by allowing continuous fibers, made of ethylene / α-olefin interpolymers, to bend to come in contact with one another in a molten state and to be heat-bonded at most contact points. The structures provided herein have desirable heat resistance, durability and cushioning property. The cushioning structures are used in furniture, vehicle seats etc.

This invention concerns an elastic multilayer composite, comprising a non-elastic film layer and an elastic nonwoven layer. This invention also concerns a process for manufacturing an elastic multilayer composite, comprising: forming the composite using a non-elastic film layer and an elastic nonwoven layer.

Fabrics and garments may include “dimensionalized” structures. The fabric may be “dimensionalized” by integrally forming a plurality of self-standing fabric surface modifying elements in the fabric material to thereby provide a fabric contact level different from (and / or reduced in surface area as compared to) the fabric base level. Garments may include this “dimensionalized” material, e.g., positioned at various locations to promote better evaporative cooling of the body or heat retention, such as along the wearer's spine, sides, and / or other locations that release substantial heat. The “dimensionalizing” structure may be formed in the material, for example, by molding, rolling, embossing, calendering, stretching, crimping, pressing, heating, and / or the like.

Unique PTFE fabric structures, and methods for making same, are described which comprise a plurality of PTFE fibers overlapping at intersections, at least a portion of the intersections having PTFE masses which mechanically lock the overlapping PTFE fibers.
