Shaped knitting is a process by which the various panels of a gannent are fonned directly in the shape needed for assembly, during the knitting process. In shaped knitting, the knitting machine can perform the following steps:

  • shaped knit garment provides the ability for the shaped knit garment to have a desired shape that cannot be prepared using a typical glove knitting machine, which can only perform tubular knitting, typically up to 4 inches in diameter at most.
  • This shaped knitting is preferred for the present invention, since the fabrics of the present invention have cut and slash resistance and are therefore extremely difficult to cut using conventional fabric cutting means. While it is possible to cut the fabric, the cutting process is very hard on the cutting surfaces, significantly reducing the interval between servicing of the cutting equipment, and thus increasing the cost of operations.

While not wishing to be bound by any particularly theory of operation, it is believed that upon trying to cut the resulting yarn, the 3 ends within the core are moving (especially with a stainless steel blade) away from the blade and not allowing the blade to bite into the yarns, and cut them.
