Problems solved by technology

[0006] The main disadvantage of a sleeve bent into a tubular shape is that the bending is accomplished by a separate step in the process of making the sleeve
The fibers making up the base layer can be bent by cold working before making the sleeve or by heating the base layer later when wound around a mandrel, but these activities constitute an additional process which increases the cost and time required to manufacture the sleeve

example 1

[0024] In an example related to Example 1, the plurality of closed chain stitch yarns 28 may comprise one or more monofilaments that replace some of the multifilament chain stitch yarns on the plurality of warp loops 29, thereby creating The sleeve fabric 14 is one or more warp loops of closed chain stitch monofilament yarn extending in length. Such circumferentially spaced warp monofilament loops 29 enhance abrasion resistance and provide enhanced protection for adjacent multifilament yarns. Accordingly, the sleeve 10 , 12 may contain monofilament and multifiber warp chain stitches 28 , 29 on the outer convex surface 27 . As mentioned above, this example achieves the classic crochet technique and has less end fraying when cold cut due to the aforementioned reasons.

example 3

Figure 5 schematically illustrates the yarns and stitches used to construct Fabric Example 3. The fabric 14 has one strand of yarn woven with a weft insertion stitch 44 over the four needles of a first bar of a knitting machine (not shown) and the other strand woven with a closed chain stitch 46 on a second bar. Yarn, another strand of yarn knitted in open warp satin or super satin trickle stitch 48 on the third bar, and another strand of yarn knitted in closed chain stitch 50 on the fourth bar . In the production example, a 2×167 dTex multifilament yarn formed of PET fibers was used for the weft insertion stitch 44 and for the closing chain stitches 46 and 50 . The open tricket stitch 48 is formed from 0.010 inch PET filaments. Having two closed chain stitches 46 and 50 bars marks this example as a classic crochet. The needle designation of the weft insertion stitch 44 , the open tricket stitch 48 and the closed chain stitches 46 , 50 are the same as in example 1. Also, as...

Abstract

The invention provides a warp knit self-curling fabric and methods of construction thereof, providing 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.
