The most popular types of threads are mercerized cotton, polyester and nylon threads. Mercerized cotton threads are strong which makes them perfect for jeans stitching where they should withstand poking by a pointy object like a pin or needle. Polyester threads are strong, but not as strong as mercerized cotton.

An Easy Way to Check Your Needle to Thread Size

  1. Grab a needle and about 12 inches of the thread you use.
  2. Thread the needle.
  3. Hold both ends of the thread and move one end up to create a 60 degree angle.  The needle should slide down the thread.
  4. Now reverse the process and see if the needle slides back down the thread.

Does the needle slide freely down the thread?  If so you know the needle is large enough – if not, your needle may be too small.  In general, you want the smallest size that will slide freely down the thread.

While there are many other features to consider when choosing the right needle for your sewing application, size is one that is fairly easy to determine and check.  Service Thread manufactures industrial threads and yarns, and has broad knowledge about industrial sewing and textile application best practices.  Let us know if you need help determining the right needle or thread size for your industrial sewing application.
