Anatomy of a Sewing Machine Needle and Functions of Each Part. What is Sewing Machine Needle? Needle is the principle element of sewing machine.

What is the function of the needle?
The basic functions of a needle
To create a passage in the material for the thread to pass through. To carry the needle thread through the material and form a loop which can be picked up by the hook or looper mechanism.
What does the needle do on a sewing machine?
Universal (Style 2020) needles are used for all woven fabrics. This needle will penetrate the fabric threads of woven fabrics. Ball Point (Style 2045) needles are used for sewing on knits; the rounded tip allows the needle to pass between the fabric threads by separating them.
What are parts of needle?
A needle has three parts, the hub, the shaft, and the bevel. The hub is at one end of the needle and is the part that attaches to the syringe. The shaft is the long slender stem of the needle that is beveled at one end to form a point.

Denim/ Jeans Heavy wovens and denims 70/10 – 110/18 These needles have a thick, strong shaft and a very sharp point. They are used for stitching denim, canvas, duck and other heavy, tightly woven fabrics. They are also ideal for stitching through multiple fabric layers without breaking.
What is the strongest sewing machine needle?
Sewing Machine Needle Sizes
- The American system uses 8 to 19, 8 being a fine needle and 19 being a thick heavy needle.
- European sizes range from 60 to 120, 60 being a fine needle and 120 being a thick heavy needle.
- Either way, the higher the number, the thicker/heavier the needle.
What is a 90 14 needle used for?
90/14 – suitable for medium weight fabrics, e.g. slightly heavier weight cotton, polyester, linen, lightweight upholstery fabric. Lighter weight fabrics such as silk (chiffon, organza, crepe-de-chine) will require a smaller sized needle. The lighter the fabric the smaller the needle required.

The most common needle gauges are 26 and 27. This gauge range adapts to all three types of injections–intradermal, intramuscular and subcutaneous.

How do you end sewing?
At the end of your line of stitching, make a very tiny stitch (this stitch should go through both layers of fabric!) and pull the thread through. Now reinsert the needle and put it through the same stitch. Pull gently on the thread and you’ll see a loop forming. Pass your needle through the loop and begin to pull.
