Warp knitting of double jacquard-patterned pile fabric

摘要

A double, jacquard-patterned piled fabric is produced on a modified warp-knitting machine having two needle-rows whose needles form needle- pairs. Each needle-pair receives a respective set of pile threads, differing ones of which are at different points in a pattern to become patterning pile threads visible in the fabric's pile pattern. When a given pile thread is to be non-patterning, it is tied into one of the two ground fabrics in the form of a walewise-running unlooped thread, and is not knitted into the ground fabric in the form of either half or full loops, in order to greatly reduce the rate of consumption of non- patterning pile thread. When a pile thread is to become a patterning pile thread, it is displaced into the zone intermediate the two needle rows and incorporated into alternate ones of the two ground fabrics in the form of half-loops. When it is again to become a non-patterning pile thread, it is returned to one of the ground fabrics and again tied thereinto in the form of a walewise-running unlooped thread.
