Abstract:
A product comprising a plurality of interlaced yarns wherein at least a first yarn having a tensile strength, having a value TS in N/tex, said first yarn containing a plurality of UHMWPE fibres having a titer, having a value T in den, wherein the ratio T/TS is at least 5 den.tex/N. The tensile strength is obtained by adjusting the drawing ratio or the UHMWPE filaments/fibres accordingly. The product shows resistance to abrasion. The product can be a rope or round slings, comprising a sheath/jacket comprising said first yarn.
Abstract:
The present invention is related to an apparatus and method for a carrier rope for use in the transport of paper webs in paper threading machine systems. The carrier rope constructed in accordance with the invention comprises a multi filament yarn assembly (A) having an initial twist, a composite yarn assembly (B) comprising mono filament yarn imparted around the multi filament yarn assembly via a second twist, wherein the multi filament yarn assembly (A) is not further twisted, a braided plait assembly (C) comprising a braid of composite yarn assemblies, and a carrier rope (D) comprising a braid of braided plait assemblies.
Abstract:
A self-wrapping, textile sleeve for routing and protecting elongate members from exposure to abrasion, thermal and other environmental conditions and method on construction thereof. The sleeve has an elongate wall constructed from interlaced yarns having interstices between adjacent yarns. At least one of the yarns is heat formed at one temperature to form the wall as a self-wrapping wall curling about a longitudinal axis of the sleeve. The wall has an inner surface providing a generally tubular cavity in which the elongate members are received. The wall also has an outer surface with a cured layer thereon. The cured layer is cured at the one temperature at which the yarns are heat formed into their self-wrapping configuration, wherein the cured layer fills the interstices between adjunct yarns to form an impervious layer on the wall.
Abstract:
A knitted convolute protective sleeve is disclosed. The sleeve is knitted from filamentary members to form alternating crests and troughs lengthwise along the sleeve. The crests and troughs may be formed by alternatingly knitting segments from relatively stiff and relatively flexible filamentary members, by interlacing stiffening hoops at spaced intervals lengthwise along a knitted sleeve having a smaller nominal diameter than the hoops, or by varying the knitting parameters, such as loop density and loop length as a function of length along the sleeve.

Abstract:
The protective tube comprises a plurality of warp-knitted threads that define a strip the longitudinal edges of which are in contact with or overlap each other, defining a substantially circular cross-section, wherein at least one of said threads is monofilament thread, characterised in that at least one of the threads is carried on two or more needles, forming a mesh at least every two passes and a maximum of every twenty-five passes.It gives the protective tube greater curvature than that of currently known tubes, closing completely without need for heating for the strip to acquire its tubular shape.

Abstract:
A warp knit self-curling fabric and methods of construction thereof provides an elongate sleeve having overlapping edges for protecting elongate members. The fabric includes warp stitches and a plurality of weft stitches. The fabric comprises at least three yarns warp knit together, wherein one of the weft stitches is knit using a tricot stitch of a monofilament under tension to bias the fabric into a self-curled configuration about a central space. The monofilament forms an inner surface of the sleeve.
