PCT No. PCT/JP96/00041 Sec. 371 Date Sep. 16, 1997 Sec. 102(e) Date Sep. 16, 1997 PCT Filed Jan. 12, 1996 PCT Pub. No. WO96/21760 PCT Pub. Date Jul. 18, 1996A composite elastic material comprises a non-woven fabric secured to an elastic member. The non-woven fabric is elastically stretchable by about 100% or more. The sheet-like elastic member has an elastic recovery of about 60% or more and a break-down elasticity of about 200% or more. The elastic member and the non-woven fabric are secured together at a plurality of points in the stretchable direction of the non-woven fabric. The composite elastic material has multiple-stage elongation characteristics including a first stress lowering point caused by changes in the structure of the non-woven fabric, and a second stress lowering point occurring at an elongation larger than that of the first stress lowering point, caused by the fracturing of the sheet-like elastic member. The elastic material clearly shows a break-down point when stretched, and increases the flexibility of designing various products.

Balloon catheter covers are elastic fabric structures of interconnected yarns, the structure having a high degree of stretch and recovery in the circumferential direction with little change in dimension in the longitudinal direction during multiple pressurization cycles over full range of inflation and deflation of the balloon catheter. The covers have longitudinal yarns positioned at about zero degrees to the balloon axis and reversibly-stretchable, circumferential yarns positioned at a high angle Ø to the axis. A method for making the balloon catheter covers allowing nearly orthogonal placement of circumferential and longitudinal yarns involves triaxial braiding a minimum number of elastomeric braid yarns with multiple axial yarns to provide maximum convergence angle (approaching 90 degrees).

A compression adjustable fabric and/or garment, system, and/or method can include a compression element (a) integrated into a fabric structure, (b) having a compressive pressure capability independent from compressive pressure capabilities inherent in the fabric structure, and (c) adjustable to provide various compressive pressures. In such a garment, the compressive pressure provided by the garment can be adjusted in all or part of the garment while the garment is being worn. The compressive pressures in different parts of the garment may be independently adjustable. The compression element can further comprise an inflatable tube and/or an electrically stimulatable yarn. The compression element can be integrated into the fabric structure by being knit into, or laid in, the fabric structure.

Paper machine clothing method including covering an extended working surface with successive layers of a resultant material. Treating each successive layer with an energy source in accordance with predetermined instructions before adding a next successive layer to build up a three-dimensional fabric structure.

Flat knitting allows production of textile structures (e.g., for use in footwear uppers) of a final desired shape such that textile cutting steps can be avoided. Flat knitted elements also can be formed directly in desired three dimensional shapes, which can help avoid the need to use additional support structures (e.g., in footwear construction). By selectively placing multiple different yarns and/or stitch patterns at multiple different locations in the overall structure during the knitting process, flat knitted products may have multiple different physical properties (e.g., different stretchability, different moisture management capabilities, etc.) at multiple different locations or zones within a single, unitary construction (e.g., different properties at different zones or locations within a single footwear structure). Additionally, flat knitting can be used to produce pockets, tunnels, or other layered structures in the final product.

A wire-reinforced webbing material is disclosed for use in furniture, bedding and the like. The webbing includes a flat knitted fabric comprised of substantially elastic yarns such as polyester. A plurality of reinforcement wires are integrally knitted into the fabric structure in a lengthwise direction. The wires may be thin-gauge titanium or titanium alloy wires.

The invention relates to an electroconductive textile material and method of preparation thereof. The method consists mainly of two stages: 1) special pretreatment of the fabric substrate for activation and making it suitable for subsequent application and strong attachment of a conductive coating with the use of a layer-by-layer technique (LBL); 2) subsequent application and strong attachment of a conductive coating by means of a layer-by-layer technique. The first stage may be carried out thermally, thermochemically, by treating in hot solutions, or plasma-chemically by plasma treatment. The pre-treatment may be performed, e.g., for swelling and/or for the formation of unsaturated chemical bonds or uncompensated charges in the fabric material. The pretreatment is needed to ensure more efficient penetration of chemical components into the fabric structure during subsequent LBL applications of treatment solutions that contain nano-particles and that determine the density of the molecular layer. The types and amounts of the nano-particles determine their charge density (solution pH is very important for charge density) in the sublayer. Such a pretreatment increases bonds of the applied layers with the substrate material.

A three-dimensional fabric structure in a form of a pocket for use in a breast reconstruction surgical procedure such as single-stage or two-stage breast reconstruction.

An example scaffold device employs a knitted mesh including at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes.

The present invention provides a fabric and a fabric structure made of yarns with reduced water absorption. The fabric comprises yarns and interstices between the yarns, the interstices between the yarns having an average width of greater than 100 μm. At least one of the yarns is comprised of multiple fibers. Said at least one yarn has voids between the fibers wherein the voids are filled up with a polymer material. The interstices remain open and the size of the interstices is the same as before the treatment. The filling of the voids between the fibers with the polymer material prevents the absorption of water into said voids and therefore leads to reduced water absorption of the fabric. The polymer material is substantially only located within the voids of the yarn and has embedded the fibers within the outer surface of said yarn.
