Our New Friction Tester

Yarn friction is a recurrent source of difficulties in knitting most products on most machines. Problems may arise from inherently high friction yarns, form variations between batches, from a rogue cone within a batch or from changes that occur in storage. Whatever their origins, frictional variations are a major cause for concern, reducing productivity, disrupting work flow, increasing rejects and lowering quality. Friction usually shows up as an increase in knitting tension. Even if the tension does not rise enough to break the yarn, then in the absence of positive feed, high friction will give tight courses resulting in barre, short blanks, or other defects.

Routine checking of incoming yarn can eliminate the problem at source by ensuring that yarns are adequately lubricated before they are issued. If problems do occur, friction testing is a powerful tool in diagnosing their cause.
