An arc resistant fabric containing a plurality of first yarns disposed in a first direction in the fabric and a plurality of second yarns disposed in a second direction perpendicular to the first direction forming a woven pattern. The first and second yarns contain non-FR cellulosic fibers, modacrylic fibers, and aramid fibers intimately blended together. The woven fabric has a sateen weave. The arc resistant fabric has a weight less than about 6 oz/yd.sup.2, an arc thermal protective value (atpv) of least about 8.0 cal/cm.sup.2, and a greater thickness than a fabric using the same yarns in a plain weave.

A cloth for mattress including a knitted fabric that is knitted from blended yarns contains flame retardant rayon fibers, modacrylic fibers, polyimide fibers, and low-melting polyester fibers. The cloth for mattress can be obtained by producing blended yarns containing the flame retardant rayon fibers, the modacrylic fibers, the polyimide fibers, and the low-melting polyester fibers, and producing a knitted fabric by knitting the blended yarns. The cloth for mattress has excellent flame retardancy, ensures easy handling when used to cover a mattress, is resistant to pilling without reducing the strength of the blended yarns, and is also safe for contact with the human body.

A sleeve for protecting an elongate member, including a bus-bar of a battery pack, and method of construction thereof are provided. The sleeve includes a knit wall having a circumferentially continuous outer surface extending along a longitudinal axis between opposite open ends. The knit wall is formed at least in part by multifilament flame-resistant yarn. The multifilament flame-resistant yarn is knit to form both the knit wall, and also first ribs extending lengthwise along the circumferentially continuous outer surface or second ribs extending annularly about said circumferentially continuous outer surface. An impervious, flame-resistant coating is bonded to an outer surface of the circumferentially continuous knit wall.

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.

Flame resistant fabrics formed with a combination of body yarns and stretch yarns that exhibit excellent physical and thermal properties. The body yarns are formed at least in part with flame resistant materials. The stretch yarns are corespun yarns having an elastic core surrounded by a fiber sheath formed at least in part with flame resistant materials. The fiber sheath protects the elastic core from direct exposure to heat and flame that would otherwise cause the core to degrade or melt.
