Wool fabrics are disclosed that have improved stretch properties. The wool fabrics can be used in numerous and diverse applications, such as to make uniforms. The fabric can be designed to have greater than 15%, such as greater than about 20% stretch in one or more directions, such as in the fill direction. In one aspect, longer wool fibers are used in the fabric in order to increase durability.

A sleeve for the construction of a hose pipe extends about a longitudinal axis. The sleeve has greater elongation capacities in one direction than in the other with respect to the longitudinal axis.

A respiratory mask including a mask fabric body (1), and one or more holding straps (3) for holding the mask body to the face of a user, the mask body being made of a woven fabric having weft yarns and warp yarns, the weft and warp yarns having a count comprised between 10 and 1100 den, the warp density being between 14-130 warps/cm, the weft density being between 12-70 wefts/cm, wherein at least part of the body is provided with a liquid-repellent crosslinked polymer.

A double-face fabric having elastic properties in its warp direction and provided with hook-and-loop properties, formed by the weaving of warp yarns and of weft yarns. The warp yarns are of four different types worked in different weaves with respect to the weft yarns, respectively: elastic yarns (A) worked in a taffeta weave; core yarns (B), formed of synthetic yarns texturized by false twist on the face, worked in a plain weave alternating with surface floats and having a linear strand density in the range from 10 to 25 dtex; core yarns (C) on the back side, formed of multifilament synthetic yarns, having a linear strand density in the range from 0.3 to 1.7 dtex, worked in a rep weave, alternating floats of great length on the back side and short binding areas on the face side, binding yarns, exclusively formed of thermo-adhesive synthetic yarns, having a melting point in the range from 80° C. to 160° C., worked in a plain weave.

Systems, methods, and structures that provide distributed acoustic sensing using chirped optical pulses of selectable duration and bandwidth, at a frame rate limited by a round-trip propagation time of a fiber under test. Instead of processing a transmitted chirped pulse as a single sequence—our systems, methods, and structures employ a parallel fragmented multiband architecture, where each tributary correlates the received signal with a truncated chirped pulse to obtain the Rayleigh impulse response over its frequency band. By reducing the duration of the chirp processed by each tributary, spatial leakage is reduced at all the tributaries, thus even after combining all the interferometric products from all tributaries using a rotated vector sum, the resultant signal is much less impacted by spatial leakage than by using a conventional TGD-OFDR method.

Weaving equipment may include warp strand positioning equipment that positions warp strands and weft strand positioning equipment that inserts weft strands among the warp strands to form fabric. The fabric may include insulating strands and conductive strands. The conductive strands may be coupled to electrical components. The warp strand positioning equipment may position the warp strands to form a shed. Component insertion equipment may be used to insert electrical components into the shed. The weaving equipment may have a reed. The reed may be used to help position an electrical component in the fabric. The weaving equipment may have take-down equipment and individually controllable warp fiber positioning and tensioning devices.

There is provided swimwear which satisfies the stretchability, strength, ease of movement, and the like desired for swimwear, has superior water repellency, and reduces friction resistance between a surface of the swimwear and water. The woven fabric for swimwear according to the present invention has a weave structure in which covering coated threads are arranged in at least a part of a warp or weft yarn, the covering coated threads each including an elastic fiber as a core yarn and a synthetic fiber filament as a sheath yarn, where, in a woven fabric structure, one of the warp yarn and the weft yarn has a larger number of float yarns. A direction with a large number of float yarns is defined as a body length (height) direction of the swimwear, a ratio of resistance yarn in a direction perpendicular to the body length (height) direction is 40% or less. The woven fabric is suitably used for swimwear.
