Minimizing Needle Heat

Introduction 
Today, most high-speed industrial sewing machines sew at very high speeds from 4,000 to 10,000 stitches per minute. Also, the most common sewing threads used for the manufacturing of apparel or non-apparel items are either polyester or nylon that have been produced using a melt-spinning process. Many of the fabrics being sewn are made from synthetic fibers that can be impacted by excessive heat.Some needle holes that appear to be needle cuts are actually caused by excessively hot needles. In this bulletin, we will discuss what causes needle heat and what can be done to minimize needle heat.
