Abstract
A warp-knitted fabric with surface interest patterning is formed from at least two full sets of threads being fed to separate guide bars of a warp knitting machine then to a single needle bed for knitting by supplying one of the full set of threads from two partial beam sets of threads. The two partial beam sets of threads are fed at different rates to the operating guide bar in a pattern. The pattern is predetermined groups of threads from one partial beam set of threads with each group being separated by at least one thread from the other partial beam set of threads.

In a method for producing warp knitted fabrics on a warp knitting machine having at least two full sets of warp threads, including the steps of feeding one of said two full sets of threads to one of two operating guide bars of said warp knitting machine and feeding the other of said two full sets to the other operating guide bar of said warp knitting machine to form a knitted fabric, there being only one thread in each guide of each operating guide bar, the improvement comprising:
- supplying one of said full sets of threads from two partial beam sets of threads, said two partial beam sets of threads being fed at different rates to said operating guide bar in a pattern, said pattern being predetermined groups of adjacent threads from one partial beam set of threads, each group being separated by at least one thread from the other partial beam set of threads.
