Definitions

  • the present invention relates to warp-knit fabrics but primarily has for its purpose the produc-- I ping, sueding, etc.
  • the present invention has been found to eliminate the foregoing'disadvantages in the handling of warp-knit fabric and comprises knitting onto the body of the fabric, simultaneously with the knitting of the body of the fabric, a non-curling selvage.
  • This method is obviously the most practical manner of producing a warp-knit fabric with non-curling selvages, both from the standpoint of production methods as well as in the lowering of the cost thereof.
  • My improved warp-knit fabric with non-curling selvages is made on a conventional tricot warpknitting machine such as is used for making laces and jersey fabrics. Such fabrics are produced upon such machines by linking 'or looping together upon the needles, the threads which are fed to the needles through guides arranged on guide bars, which guide bars traverse the desired distance from right to left in the making of the fabric desired. 20 In my improved fabric two or more warp or body threads are employed in making the fabric '(two being shown in the drawing) as A, B.
  • This additional set of threads is fed through 35 guides arranged on an additional guide bar which is arranged back of the front and middle guide ries, in addition to the number of threads necessary to produce the desired width offabric, a sufllcient number of extra threads to produce one inch, which may be more or less, of extra fabric on either side of the main body of the fabric.
  • the back guide bar is used to carry the same number of threads, and in the same relative position, as the extra threads on the middle guide 'bar. These threads are indicated by the letter C. 66
  • the C threads carried by the back bar are laid in the fabric by the bar ascending so that its guides are between the needles and descending so as to bring them between the same needles although it does not return until the threads from the middle guide bar have been lapped or looped over the needles.
  • the threads from the back bar are thus trapped or inlaid by the threads from the middle guide bar and held by them.
  • the back bar When the back bar has returned below the needles, it traverses a-plurality of needles to the right, and then after going up through the needies and repeating the process above described and returning again through the same needles traverses back to its first position. This is done, simultaneously with the operation of the front and middle guide bars, on both sides of the main body of the fabric.
  • the back bar traverses a plurality of needles and, when the end of such traverse is reached, goes up between the needles then adjacent to the guides and returns between the same needles without lapping or looping its threads over those needles, as the middle guide bar in the meantime will have done with its threads.
  • the selvage may be formed from a single thread running from a cone on either side of the warp threads and the single thread be traversed back and forth the desired number of wales to obtain the flat and noncurling selvage.
  • a tricot warp knitting machine having only two bars may be employed and an attachment placed thereon to guide the threads C over and under the loops of the main fabric at the edges to form the selvage.
  • the gist of the invention therefore resides in the knitting of a non-curling fabric in the form of a selvage which is made simultaneously with and as a part of the warpknit main body portion of the said fabric;
  • a fiat knit-warp fabric having incorporated therein at least one unknit thread along each selvage, each unknit thread extending inwardly over only a limited number of wales whereby the central portion of the fabric is devoid of unknit threads.
