  • Patent number: 6170531
    Abstract: The invention relates to a flexible tubular lining material which comprises a seamless plush textile tube and a plastic film layer arranged coaxially and freely around it as well as a method for the production of conduit and/or pipe linings which comprises impregnation of the flexible tubular lining material with a curable resin composition, the introduction of the impregnated material into an inversion tube, the subsequent pressing of this arrangement into the conduit or pipe section to be lined and the curing of the resin under maintenance of applied pressure in the inversion tube.

  • Patent number: 5156589
    Abstract: A cohesive bandage fabricated according to a method comprising the steps of providing at least one layer of woven fabric and applying a coating containing polybutylacryate ester and alkyphenyl polyethylene glycol ether to at least one fabric face is disclosed. In one embodiment, the coating is applied by an airless method microselectively in statistical distribution where the quantity of coating is controlled by pump pressure. Alternatively, an aqueous dispersion of polybutyl acrylate ester and carboxymethyl cellulose is microselectively and cohesively coated on both sides of the fabric by screen printing to produce a regular dot pattern on both faces of the fabric.

  • Patent number: 4984570
    Abstract: The textile fabric is used as a wound dressing in much the same way as dressing gauze with improved characteristics compared with the latter and comprises a central web portion of man-made fibers having a high surface tension, and on either side thereof web portions formed from absorbent, cellulosic yarns. The central web portion is connected by looping to the outer web portions so that after folding, a nonstick wound dressing is obtained in which the hydrophobic man-made fibers functioning as the wound covering, come to rest on the wound, while the folded layers of cellulosic fibers behind it, act as an absorbent layer.

  • Patent number: 4699133
    Abstract: The invention relates to a cohesive, self-adhesive, rigid or elastic bandage for fixing, compression and support dressings and permanent elastic compression and support dressings for medical purposes and a process for the manufacture thereof. The bandage comprises a web of warp and weft threads or warp threads in the form of a woven fabric having a porous structure and an amount of ultra fine particles of an adhesive, such as a rubber adhesive, distributed over and bonded to both the exposed surfaces of the warp and weft threads to provide adhesive particles bonded to the threads on both sides of the fabric. The adhesive particles are uniformly distributed over both bandage surfaces without the fiber groups adhering to one another or to the projecting fiber ends of the two surfaces, the particles being of a size distribution and amount sufficient to provide adhesion between overlying bandage surfaces without substantially reducing the porosity and elasticity of the fabric.

  • Patent number: 4476697
    Abstract: The invention relates to a wound dressing which prevents or at least reduces sticking of the dressing to the surface of the wound due to contact with moisture from the wound and which without the use of over twisted threads has a controllable lifting action and an excellent secretion-absorbing action, whereby cutting of the dressing into strips does not lead to lateral fraying due to the cutting of the mesh as is the case with known knitted fabrics and in which the further use leads to complication. The present wound dressing comprises a knitted fabric formed with a basic stitch construction and with a plurality of inlay threads having a Z or S twist, the yarns of the inlay threads having the same thickness and twist, and being inserted as slightly or greatly displaced wefts.

  • Patent number: 4424808
    Abstract: The invention relates to a fabric which is highly longitudinally elastic in the warp direction and easily tearable in the weft direction, or highly longitudinally elastic in the weft direction and easily tearable in the warp direction, or highly longitudinally elastic and easily tearable in both the warp and weft directions, which is adhesively or self-adhesively coatable and has a crepe structure, whereby in bandage form it can be used as a fixing and compression bandage after distortions, luxations, fractures and similar injuries, as well as preventatively against injuries liable to occur when playing sports.

  • Patent number: 4236550
    Abstract: The invention relates to an elastic muslin bandage with in part elastic and non-elastic threads and with non-elastic weft threads which can be used elastically and as a fixing dressing having a high elastic behavior, permits an easy application to conical extremities and joints, is conductive to moisture and heat so that no moisture and heat chambers form, and in which slipping of the individual bandage layers is prevented, whereby the bandage is constructed in such a way that in the warp the web has textured polyfilic polyamide threads of thickness Td 70/13/2 or a lighter or heavier titre varying therefrom as the elastic element and threads of 17 tex staple fibre and/or bleached cotton of size Nm 60 or the like as the rigid element in a ratio 1:1, 1:2, 1:3, 2:1, 2:2, 2:3, 2:4 or the like, and in the case of a ratio of 1:1 in a number of 59 textured polyfilic polyamide fibres and 58 staple fibres based on the web width of 10 cm, and in the weft threads of 17 tex bleached cotton and/or staple fibre or a blende
