Aspects herein are directed to a woven, breathable textile. The textile comprises a first woven zone and a second woven zone, where the first and second woven zones are integrally woven such that a particular warp yarn extends through both the first woven zone and the second woven zone of the textile. The first woven zone comprises a first woven layer and a second woven layer with a space or void formed between the first and second woven layers. The second woven zone comprises a single woven layer comprising a plurality of apertures formed through the weaving process, where each aperture is located at the center of a repeating pattern of interlacings.

A fabric can comprise yarns comprising less than about 30 denier total and less than about 10 denier per filament; a density of greater than about 177 yarns per cm.sup.2; and a thickness of less than about 3.2 mil. The fabric can further comprises a weight of less than about 60 g/m.sup.2. The fabric can have performance characteristics equivalent to or greater than those in conventional implantable fabrics. A method of making such a fabric can include twisting together filaments into a multifilament yarn; passing adjacent yarns into a loom in parallel so as to allow the yarns to be woven together more closely; maintaining a consistent tension on the yarns during placement of the yarns on a loom beam and during weaving; and or subjecting the fabric to increased heat and pressure so as to compress the yarns more tightly.

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.

The invention addresses the problem of providing a cloth and a protective product, which are excellent not only in flame retardancy but also in protection performance against electric arcs, and can further be provided with any color appearance. As a means for resolution, in a cloth including a flame-retardant fiber, a UV absorber or carbon particles are contained in the cloth, and the cloth is configured to have a lightness index L-value of 25 or more.
