Definitions

  • This 'lnvention comprises improvements in knitted fabric and in the production thereof. More particularly the invention refers to fabric of a kind wherein, for the purpose of minimizing stitch running or laddering in the event of thread 1 breakage, locked stitches are formed in the fabric 1 bypassing a thread loop through and also around a stitch loop, the stitch-locking thread being coiled around each leg or side of the stitch loop.
  • the object of the present invention is to render the ladder-proof properties of fabric of the aforesaid kind more positive or definite, to provide the fabric with a degree of elasticity in the direction of the stitch courses which is equal to and even greaterthan that of ordinary knitted fabric and also preserve the normal elasticity in the direction of the stitch wales, to produce a fabric which is capable 0f quick recovery to normal ,after being repeatedly stretched, and also provide a fabric having a substantially smooth and even surface.
  • Fabric possessing the combined properties as above can be knitted in fine gauges from silk or artificial silk yarn and can be employed with advantage in the production of underwear and other articles of clothing; although the field of utility of the fabric is not restricted to such articles.
  • the locking loop to anchor or grip the released loop and thereby prevent or minimize the possibility of laddering. It is found, however, that if the loop of locking thread is of 50 insuflicient length or size in relation to the stitch loop with which it is associated same may slip back over and through said stitch loop and thereby release same, whereas if the locking thread loop is sufilciently long or large in relation to t5 the stitch loop, said locking loop will continue to have frictional or looking engagement with the stitch loop and will be prevented or restrained from slipping back through the stitch loop when the latter becomes tightened.
  • the present invention resides-in the provision of knitted fabric embodying locked or tied stitches of the kind referred to wherein the amount or length of thread introduced to form a number of successive stitch-locking loops is substantially greater than the amount of thread introduced to form the stitches locked thereby, and wherein the length or size of a stitch-locking loop (the amount of thread in said loop) is greater than the 'lengthcrzsize of the stitch loop to be locked (the amount of thread in said stitch loop) to such an extent that, in the event of said stitch becoming released by thread breakage from its interlinking engagement with another loop in the ordinary stitch loops i same wale, said locking loop does not slip back completely out of locking or frictional gripping engagement with the stitch loop.
  • a feature of the invention also resides in the provision of knitted fabric as last described wherein the size or length of the loops of locking thread is substantially equal in the needle or stitch wales and in the sinker wales.
  • each stitch loop i in each knitted course is locked or tied by a stitch-locking loop 2, the stitch-locking thread In. from which the locking loops 2 are formed being finer or thinner than the stitch forming thread la.
  • the released stitch loop which is shown pulled straight or substantially straight by virtue of lateral tension applied to thefabric, takes the form of a thread bar 4.
  • the stitch-locking loop associated with the released stitch loop is, however, of such a relative length or size that when said released stitch loop is pulled straight or substantially straight to form the bar 4 there still remains sufficient slackness in the locking thread to maintain a loop 2b, and this locking loop is maintained in engagement with the thread bar 4 and becomes anchored between same and the next previously formed stitch loop lb in the same wale, thereby preventing or resisting further stitch running down the wale.
  • each successive stitch in a course of stitches is locked or tied as above, for every 10 inches of stitch-forming yarn la inserted into the fabric to produce the to be locked there is at least one additional inch of stitch-locking thread 2a inserted; in other words, the amount or length of stitch thread and stitch-locking thread may be in the ratio of 10 to 11.
  • the amount of stitch-formin thread introduced into a stitch course is advantageously 30 inches. and the amount of stitchlocking thread 33% inches.
  • each stitch to be locked may have associated with it a plurality of stitch-locking loops, e. g. two loops, each passed in a similar manner through and around the stitch loop. In other words there may be more than one locking thread 2a introduced into a course of stitches.
  • the loops of stitch-locking thread 2a are of substantialiy uniform size in the needle or stitch wales, and in the sinker wales of the fabric; in other words the stitch-looking thread is substantially evenly divided between the needle wales and the sinker wales.
  • the elasticity of the fabric is in no way impaired, and a fabric is produced having a smooth or substantially smooth or uniform surface, that is to say a surface without comparatively long plush or pile loops projecting therefrom.
