This document describes textile assemblies for speakers, including textile assemblies with inlaid tensioning yarns, and associated apparatuses and methods. The textile assembly includes a textile body (106) with inlaid tensioning yarns (302, 304). The textile assembly (102) may be a fully-fashioned textile swatch. The tensioning yarns are inlaid at intervals in the textile body but can slide within or be pulled through the textile body. Further, the tensioning yarns have ends (306, 308, 402, 404) that are accessible near the edges of the textile body for various reasons. First, pulling on them while the textile assembly is on an acoustic device (104) tensions the tensioning yarns such that they limit movement of the textile assembly and break up vibration modes. Second, their ends can be tied directly to, formed into loops to hook over, or wound around, features (208) on the acoustic device to removably secure the textile assembly to the acoustic device.

A structure includes an oriented piezoelectric polymer arranged in a circular tubular or circular columnar shape, wherein the orientation angle of the piezoelectric polymer with respect to the central axis of the structure is 15° to 75°, the piezoelectric polymer includes a crystalline polymer having an absolute value of 0.1 to 1000 pC/N for the piezoelectric constant d14 when the orientation axis is the third axis, and the piezoelectric polymer includes a P-body containing a crystalline polymer with a positive piezoelectric constant d14 value and an N-body containing a crystalline polymer with a negative value, wherein for the portion of the central axis of the structure having a length of 1 cm, the value of T1/T2 is 0 to 0.8, T1 being the smaller and T2 being the larger of (ZP+SN) and (SP+ZN), where ZP, SP, ZN, and SN are particularly defined masses.

The invention relates to a compression bandage comprising a nonwoven-based bandage layer that has been stitched over with elastic textile threads by stitch bonding methods, the textile threads being heat-shrinkable and not elastomeric and the compression bandage having an elasticity after heat shrinking of the textile threads by 50-200%, particularly 50% to 90% and especially 50% to 70%. The invention also relates to a compression bandage combination.

There is provided herein a compression dressing comprising a first cushion layer (1) and a second support layer (2) wherein the two layers (1,2) are connected to each other in the unstretched state by means of a stich-bonding process via an elastic sewing thread, the stich length being 1.5 to 3mm/U at a sewing thread tension of at most 4 cN.

A knitted textile having a first layer including a first yarn with a thermoplastic composition integrally formed with a second layer including a second yarn, the first yarn forming an array of knitted patterns defining voids through the first layer to the second layer. The first layer may be heat treated to form a film. Treatment of the first layer may change zonal and directional tensile properties of the knitted textile. The Poisson's ratio of the knitted textile may be greater than or equal to zero in a first axis and/or a second axis, before and/or after treatment. Articles of apparel, including articles of footwear and garments incorporating the knitted textile, and methods of forming the knitted textiles and articles are disclosed.

The disclosure discloses a washable flame retardant viscose fabric. The viscose fabric includes a flame retardant viscose fiber; and a method of preparing the viscose fiber includes the following steps: impregnation, squeezing, ageing, yellowing, addition before spinning, spinning, bundling, drafting, cutting off, first washing, desulfurization, second washing, pickling, third washing, application of oil bath, drying, and packaging. Before spinning, an aqueous dispersion of flame retardant, an aqueous dispersion of hyperbranched nanocellulose and a dispersant are uniformly added to a spinning glue using a pre-spinning injection system. During the production of the flame retardant viscose used, the aqueous dispersion of flame retardant, the aqueous dispersion of hyperbranched nanocellulose and the dispersant are introduced into the spinning glue by the pre-spinning injection system before spinning, so that the flame retardant has a high residual rate in the subsequent coagulation bath.
