The present invention relates to a prosthetic knit based on at least a first yarn of biocompatible polymer material defining first and second opposite and openwork faces, and on at least a second biocompatible and heat-fusible monofilament yarn, forming barbs that protrude outwards from at least said first face and are obtained by melting loops generated by said second yarn, the chart followed for the knitting of said first and second yarns on a warp knitting machine having three guide bars B1, B2, B3 being the following, according to the ISO 11676 standard: —Bar B1: 1.0/0.1//—Bar B2: 1.0/7.7/6.6/7.7//—Bar B3: 2.1/5.5/3.4/0.0// said second yarn following the chart of bar B3. The present invention also relates to a process for manufacturing such a knit.

The present invention relates to a bidirectional low tearing strength spacer textile using warp knitting, more particularly, relates to a spacer textile comprising a surface textile layer, a rear surface textile layer, and a spacer thread connecting the textile layers, wherein the surface textile layer and the rear surface textile layer include a main thread provided with a plurality of open loops formed with openings in a longitudinal direction.

An auxetic polygonal cell may have a plurality of chiral structures capable of rotation. The plurality of chiral structures may at least partially enclose a volume. Each of the chiral structures may include a first cross member having a first set of distal ends and a second cross member intersecting the first cross member, the second cross member having a second set of distal ends. The chiral structures may also include a first set of legs, wherein each leg of the first set of legs extends from at least one distal end of the first set of distal ends and a second set of legs, wherein each leg of the second set of legs extends from at least one distal end of the second set of distal ends.

A warp-knitted spacer fabric has a first and a second planar warp-knit layer that are joined together by spacer yarns. The first warp-knit layer is formed by a first yarn system having a first pattern and a second yarn system having a second pattern. The first pattern is a modified pillar-stitch in which the yarns of the first yarn system form pillar stitches in alternating sequence in the working direction and are guided without formation of stitches, and the yarns of the second yarn system are each guided over at least two adjacent stitch wales and running in the working direction. The second warp-knit layer has openings formed by a plurality of stitches.

Knit fabrics having ceramic strands, thermal protective members formed therefrom and to their methods of construction are disclosed. Methods for fabricating thermal protection using multiple materials which may be concurrently knit are also disclosed. This unique capability to knit high temperature ceramic fibers concurrently with a load-relieving process aid, such as an inorganic or organic material (e.g., metal alloy or polymer), both small diameter wires within the knit as well as large diameter wires which provide structural support and allow for the creation of near net-shape preforms at production level speed. Additionally, ceramic insulation can also be integrated concurrently to provide increased thermal protection.

Systems, apparatuses and methods may provide for a clothing article including a first fabric having a first set of threads coupled to one another, wherein each thread in the first set of threads includes a metal compound with electropermanent magnet properties. Additionally, a second fabric may be coupled to the first fabric, wherein the second fabric includes a second set of threads having the metal compound with electropermanent magnet properties. In one example, electrical current may be applied to one or more target threads, wherein the electrical current may initiate a slide of the first fabric across the second fabric and/or initiate creation of a fold among the target threads.
