Effect of Needle Size



Effect of needle size can be described into two ways. These are:
  1. If the needle finer than thread.
  2. If the needle coarser than thread.
If the needle finer than thread:
  1. For finer needle size of needle eye is small. As a result thread can not easily pass through the needle eye.
  2. The friction between needle and thread increased. As a result frequent thread breakage may occur as well as thread may burn due to heat production.
  3. Thread cannot easily pass through the fabric. As a result friction between thread and needle increased. So, fabric may be damaged due to excessive heat production.
  4. Due to frequent thread breakage mechanical failure will be held frequently. As a result production will be delay.
If the needle coarser than thread:
  1. Thread can easily pass through the needle due to improper tension on the thread loop formation by needle may not uniform which leads to defective seam.
  2. Due to improper tension on the thread slipped stitch may form.
  3. Due to bigger needle size, the hole in the fabric is bigger size as a result fabric my be damaged as well as seam pucker may occur.
