  • Patent number: 5229181
    Abstract: A wiper for use in cleanrooms and other controlled environments is made using a knit fabric tube rather than a fabric sheet. The fabric tube is knit with a diameter approximately equal to the preferred wiper dimension and is presented directly to an apparatus for sealing and cutting. A sequence of spaced strips are fused into the fabric tube perpendicular to its length. Individual two ply wipers are separated from one another along a cut line midway in the strips. The wipers are characterized by lower costs due to fewer fabrication steps and a 50% reduction in the number of wiper edges requiring treatment.

  • Patent number: 5131099
    Abstract: The sock is produced as a knitted mesh article and at least in the sock leg has concave holding elements formed as thread bows and which are directed in the direction towards the foot. The height-to-length ratio of the thread bows directed downwardly is selected such that the loops when wearing on the leg and in the case of leg movements serve to produce a movement of the entire mesh article, e.g. sock, in the direction away from the foot. The holding elements are formed as the meshes of a loop plush, in which the loops serving as the holding elements are constituted by the thread bows. This is achieved in simple manner in that at least part of the meshes are formed from a plush thread and a basic thread, whereof the mesh head is directed towards the edge of the sock while the holding elements in the form of loops are directed towards the foot. Thus, the sock can be manufactured as a loop plush.

    Abstract: Protective blanket for hoofed and domestic animals, in particular horses and dogs, to protect against the influences of cold in cold weather or due to evaporation of the skin moisture after physical exertion, and for thermal treatment of certain ailments, e.g. influenza or kidney trouble. Woolen or linen blankets have the disadvantage of not giving off the evaporation moisture and do not provide warmth when wet. The protective blanket according to this invention provides better heat protection and has a therapeutic effect due to the fact that it consists of two mutually movable layers of a knit fabric (6) made of nonhygroscopic synthetic fibers fit for generating static electricity and with a mesh of 50-125/cm.sup.2. For choice, the blanket contains a synthetic foam lining permeable to air between the two layers of fabric (6).

  • Patent number: 4497187
    Abstract: A burning wick for hydrocarbons and the like is manufactured by continuously forming two wick bodies by two juxtaposed raschel knitting machines, and then fastening the two bodies together transversely along spaced lines, by wrap yarns or other linking yarns. The composite strip thus formed is then cut off along those transverse junction lines, to provide a plurality of separate cylindrical sleeves, each of which serves as a wick. The individual knit wick bodies can have various weaves across their transverse width, such as a burning portion at one edge, an intermediate suction portion for drawing up the fuel, and a bending or stretching portion between the edges of the body and characterized by a reduced number of weft yarns. In this way a cylindrical wick is produced which has various characteristics along its axial length.

  • Patent number: 4463486
    Abstract: A velvet-type or snap-together fastener web comprises a warp-knitted ground structure and series of interlooped loops disposed in at least every other wale, each loop including a pair of mushroomed stems projecting from the wale at each course. To produce such a fastener web, a double-faced fabric is knitted on a Raschel warp knitting machine, and is separated into a plurality of strips by dissolving transversely spaced water-soluble threads in the fabric. Each strip is divided into front and back fabric webs by severing thermoplastic thread portions therebetween, leaving a multiplicity of raised stems on each fabric web. The raised fabrc stems are then heated to mushroom their ends.

  • Patent number: 4419868
    Abstract: A warp-knit stringer tape for slide fasteners has a wale-free coarse region extending between a pair of longitudinal warp-knit webs for easy attachment to a knit fabric. The two webs are interconnected by a connector thread extending transversely across the wale-free region. The innermost wale and the next one or two in each web are disposed closely to one another, thereby providing a widened and thus reinforced wale along the wale-free region. No heavy or thickened yarns are used for the chain stitches of the innermost opposite wales of the webs, and hence there appear no bulged or increased-thickness wales along the wale-free region.
