Provided are a base cloth for a material and a manufacturing method therefor, the base cloth suppressing opening of a boundary portion between an expanding part and a non-expanding part when used in a bag body, having low dynamic air permeability, and being capable of exhibiting the characteristic of being unlikely to burst even at high temperatures. A fabric base cloth for a material according to the present invention is composed of fibers having a prescribed thread breaking strength value, and for which the cloth surface is not subjected to resin coating, laminating, or a resin impregnation treatment.

A weaving loom for weaving a multilayer fabric with weft insertion mechanism (90) and main heddles moved by a Jacquard main shedding mechanism for guiding main warp yarns (12) and defining a main harness width (W11). According to the invention, the weaving loom includes auxiliary heddles (21) moved by an auxiliary shedding mechanism, for guiding auxiliary warp yarns (22) and defining a clamping area (W21) arranged within the main harness width (W11). At a first pick, the auxiliary heddles are configured for closing the auxiliary shed of auxiliary warp yarns for clamping an inserted weft (100) while the main shed is still open.

A planar, flexible textile element, which is particularly suitable as a baby sling, consists of at least 90% natural fibres and/or fibres made of natural fibres and has a net structure. In this case, a main part having the net structure and an elastic edging enclosing the main part are provided.

A method for producing an annular hair band includes providing an elongated, elastic woven strip having transversely extending yarns interleaved between longitudinally extending yarns. Two ends of the woven strip are overlapped. An abutting area of the two ends is greater than a cross sectional area of an end face of each end. Two non-planar dies are used to heat and compress overlapped sections of the two ends. The yarns of one of the two ends and mesh holes of another of the two ends are fused together. The two ends are flattened to form protrusions or grooves on an upper face and a lower face of a non-planar engaged portion of the two ends, thereby forming the annular hair band. The two non-planar dies are opened to remove the annular hair band for cooling. The annular hair band is capable of withstanding a stretching force greater than 2 kg.

The present application is at least directed to a curved band having a plurality of warp yarns and a plurality of weft yarns. The curved band includes a first portion and a second portion. The first portion of the curved band has a first weaving density. The second portion of the curved band has a second weaving density that is less than the first weaving density. The curved band is configured to curve toward the second portion in response to contraction of the warp yarns.

The present invention discloses an anti-gravity backpack, which comprises a backpack body and two shoulder straps. A supporting plate is provided on a back of the backpack body, and a pressure reducing plate is provided on a back of the supporting plate. A first elastic band and a length fixing band are provided between the pressure reducing plate and the supporting plate. The existence of the pressure reducing plate, the first elastic band and the length fixing band causes the backpack to bounce up and down to act as a buffer, which not only relieves the pressure on the wearer's shoulders but also saves the wearer's energy with the resilience produced by the elastic band, thus helping slow down the wearer's rate of muscle fatigue and make the wearer feel less burden on the body.

Woven preforms, for example those used for jet aircraft engine fancases, may need additional stiffeners to improve the strength and/or dynamic performance of the preform assembly, as well as to serve as attachment points. The present invention describes several improved woven preforms that include circumferential or axial stiffeners, as well as methods of manufacturing the same. One embodiment includes circumferential stiffeners added to a woven preform. Another embodiment includes sub-preforms with integral flanges that combine to make integral stiffeners. A further embodiment includes an intermediate stiffener wrapped onto a base sub-preform wrap, wherein the intermediate stiffener wrap incorporates intermediate stiffeners. Another embodiment incorporates bifurcations in one or more layers of an outermost wrap of a multi-layer fabric composite that forms a preform, wherein the bifurcated outer wrap is folded to form stiffeners that may be oriented circumferentially or axially.
