Sewing Machine Needles and Their Uses

A needle is always the most important component of any sewing operation, whether done by hand or with the help of a machine. We cannot, however, use the same needles for hand stitching and machine sewing. The aim of the machine needle is to produce a hole in the fabric so that the sewing thread can flow through. It also permits the thread to form a loop, completing the stitch.
The following components make up a sewing machine needle:
- 1. Butt – at the very end of the needle. It’s used to connect the sewing machine to the needle.
- 2. Shank — the needle’s foundation and widest section. It is attached to the needle bar and is placed under the butt. Flat and cylindrical shanks are the two types of shanks.
- 3. The shank is followed by the shoulder. The friction between the needle and the fabric is reduced.
- 4. The narrowest component of the needle is the blade. Of course, this is where the needle and the fabric have the most friction.
- 5. Long groove — minimizes friction between the needle, fabric, and sewing thread.
- 6. Short groove — the area between the needle’s tip and the eye. It uses the sewing thread to construct the loop.
- 7. The eye of the needle is the orifice at the top of the needle. Its main function is to keep the thread together.
- 8. The curving slot above the eye that seals the gap between the looper and the needle is known as the scarf.
- 9. Point – The needle’s sharp tip and the first point of contact with the fabric.
Universal, sharp, and ballpoint needle points are the three most popular types. But keep in mind that various fabrics demand different needle points. When sewing straight lines, we utilize the sharp point. Ballpoint needles are used while knitting fabric because the point needs to glide between the loops without harming the fibers or the fabric.
Obviously, universal needles can be used on both types of fabric. This is due to the fact that a universal needle’s point is both sharp and rounded, giving it the qualities of both sharp and ballpoint needles.
Sewing Machine Needles Types and Names

There are many different types of needles available, however the following are the most common:
- 1. Round point needle: This is the most common variety because it is utilized in practically every type of sewing project.
- 2. Ballpoint needle – utilized for elastic textiles since the needle passes through the fiber rather than over it, keeping the fabric’s flexibility.
- 3. DI leather needle — a needle designed specifically for dry, heavy, and hardened leather. As a result, the diamond shape of the blade allows the needle to cut rather than rip the fiber.
- 4. SD1 needle – a smaller version of the DI needle with a smaller cutting tip. This tiny tip not only cuts but also moves the fabric sideways.
- 5. Serv7 needle — a scarf-shaped needle with a sharpened blade for cutting hard-to-cut materials.
- 6. Twin needle – a twin needle is made up of two needles that are connected together on a single carrier. As a result, it’s perfect for sewing double decorative stitches. Don’t be fooled by the 4.0/80 rating. The first number indicates the distance between the two needles in millimeters, while the second indicates the needle size.
- 7. Tri-needle — this needle is used to sew triple ornamental stitches, as the name implies. They’re branded 2.5/80, which is the same ratio as the one on the twin needle label.
- 8. Embroidery needle – this sort of needle is used with particularly sensitive twine, and it has a larger than usual eye to avoid harming the twine.
- 9. Metallic needle – This needle type has a stretched eye form, which is required to prevent the twine from curling.

What Size Sewing Machine Needles Should You Use?


How are Sewing Machine Needles Numbered?
- The sewing machine will not switch on.
- Foot control isn’t working.
- The threader is out of control.

Sewing Machine Needles and Threads

- To avoid knots, the needle thread must be able to pass through the eye of the needle.
- Make sure the thread’s strength surpasses the fabric’s strength to avoid injuring it and preserving it.
- Because the stitches must be equal, a thread with excellent flexibility throughout its length is required.
- Control the amount of friction between the needle and the thread, as well as the thread and the fabric, because too much friction will cause the thread to brake, and too little friction will prevent the stitches from locking and causing seam run-back.
- Abrasion resistance is essential for effective sewing results.
- The sewing thread must be flexible enough to maintain its shape while also keeping its qualities in the seam after the sewing operation is completed.
