Impact of Sewing Needle Coating on Needle Heating

Original language description

Sewing needle heating is a common problem in the sewing of technical and medical textiles. The hot needle causes burnt spots on fabric, the breakage of thread and weak seam strength. The most economical way of reducing needle heat is to use thread lubrication, needle coating or air cooling. Multiple coated needles are commercially available on the market, including those coated with Nickel, Chromium, Ceramic or Titanium Nitride, etc. In this research, the needles are coated with Diamond-Like Carbon (DLC) for improved frictional properties. Commercially available needles are compared with the DLC-coated needles for sewing performance and needle heat. The results shows a significant decrease in needle friction as compared to the classic needle but the commercial needles coated with Titanium Nitride still performed better. Also, the coating of DLC peeled off in a shorter time during high-speed sewing; within 15 cycles of continuous sewing, there was a significant loss of coating near the needle eye. The novel DLC technique can be of future benefit to sewing needles, offering an improved technique and more cost-effective approach. The results for the DLC-coated needles showed a 9-12% reduction in the needle temperature and, overall, a 12-14% rise in the tensile strength of the thread after sewing as compared to sewing by classical needles.
