The invention relates to a knit having barbs protruding outwards from both faces obtained by knitting yarns of biocompatible material in guide-bars B2, B3 and B4 of a knitting machine, wherein the knitting patterns followed by guide-bars B2 and B3 involve at least two needles and produce an arrangement of yarns defining two faces of the knit, the knitting pattern followed by guide-bar B4 making stitches generating loops protruding outwards from each of the faces of the knit, guide-bar B4 being threaded with a hot-melt monofilament yarn, heat-setting the knit, forming barbs by cutting the loops via melting.

One or more electrical components may be incorporated into a fabric seam. The fabric seam may join two pieces of material in a fabric item or may form the border of a fabric item. The fabric seam may include first and second fabric portions with one or more conductive strands extending between the first and second fabric portions. An electrical component may be coupled to the conductive strand. The fabric seam may have one or more side pockets for capturing the edge of a material such as a piece of fabric. The fabric seam may have gaps that allow conductive strands within the fabric seam to branch off in different directions. Openings may be incorporated in the fabric seam to allow air or light to pass through and/or to form a window for an electrical component in the fabric seam.

The present invention discloses a method for producing unidirectional hybrid-braided fabrics, including: preparing a first layer of 0° warps; preparing a second layer of 0° warps to a Nth layer of 0° warps; preparing an auxiliary layer of wefts; preparing binding yarns; laying and hybrid-braiding the materials prepared in steps 1-4 to obtain unidirectional hybrid-braided fabrics; and cutting and winding. The 0° warps and wefts of the invention are made of two or more layers of different fibers that are laid in a single direction and finally hybrid-braided. Therefore, two or more different types of materials can be laid, thereby ensuring the uniform distribution and thickness of the fibers in different areas of the hybrid-braided fabric. The grammage of different 0° warp fiber layers can be adjusted freely in a range of 30-3000 grams/m.sup.2, thereby realizing performance and cost designability of a composite material.

A double-knit fabric containing a first knit layer, a second knit layer, and a plurality of stuffer yarns. The stuffer yarns are located between the first knit layer and the second knit layer. The double-knit fabric contains a plurality of anchored regions and a plurality of detached regions. In the anchored regions, the first and second fabric layers are knitted together and in the detached regions the first and second fabric layers are unattached. The average peak distance between the first and second fabric layers in the detached regions is at least about 3 mm and the double-knit fabric has between about 10 and 30 detached regions per square inch. The anchored regions contain at least two knit stitches in at least one direction and the anchored regions have a width of at least about 1 mm.

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.

For the purpose of providing a skin material that is easily bonded to a base material, an interior material including the skin material, and a method for manufacturing the interior material, a skin material includes a base cloth layer and a design layer. The base cloth layer includes a surface fabric and a back fabric, and a binding yarn that binds the surface fabric and the back fabric. The binding yarn is erected between the surface fabric and the back fabric to form a void inside the base cloth layer. An embossed pattern is formed in a concave shape on the skin material from the design layer side. A thin portion is formed in a band shape in a peripheral edge portion of the skin material. The skin material is bonded to the base material to obtain an interior material.
