How Do Sewing Machine Needles Work?


Sewing machine needles are designed to pierce the fabric and create a stitch. They are typically made from steel or other strong materials and have a sharp point at the end.

The shaft of the needle is slightly tapered which helps it penetrate the fabric more easily.

Sewing machine needles come in a variety of sizes depending on the thickness of the fabric being sewn.

The size is usually indicated by a number on the needle (e.g. size 5 needle).

The larger the number the thicker the fabric can be.

Most sewing machines use two types of needles: straight stitches and zigzag stitches. Straight stitch needles are used for basic stitching while zigzag stitches are used for more decorative stitching.

Some sewing machines also have special needles for specific tasks such as buttonholes or embroidery.

How Does A Sewing Machine Needle Work?

There are a couple of different types of sewing machine needles. The most common type is the sharp needle.

It has a sharp point and a small hole in the middle.

This type of needle is used for general sewing.

Another type of needle is called the ballpoint needle. It has a round point and a large hole in the middle.

This type of needle is used for sewing fabrics like knit or stretch fabric that can’t be pierced with a sharp needle.

The ballpoint tip spreads the fibers as it moves through the fabric which prevents runs and pulls from happening.

How Does A Needle Pick Up Bobbin Thread?

Are you familiar with the anatomy of a sewing machine needle?

If not let’s take a quick look. A sewing machine needle has a sharp point at the end that penetrates the fabric and a shaft that fits through the needle bar.

The eye of the needle is where the thread goes and it’s also where the thread forms the loop that catches the bobbin thread. 

Now let’s talk about how a needle picks up the bobbin thread.

When you lower the presser foot it catches hold of the top thread and pulls it down towards the feed dogs.

At the same time the needle begins to move up and down (this is called stitch formation). As the needle moves down it enters the fabric and then starts to come back up.

As it comes up it catches the bobbin thread and brings it up through the fabric. The top thread and bobbin thread now form a loop.

This loop is called the stitch formation.

As the needle continues to move up and down it forms stitches that hold the fabric together.
