What You Should Know About Denim

If you want to sew jeans and you need a sewing machine, first you should do some research about denim as a fabric. The word ‘denim’ actually comes from the city of Nimes in France. Originally called “serge de Nimes”, it was not the fabric we know today. It was a combination of silk and wool. In the 17th century, Levi Strauss & Co designed the first work pants. The work pants made of denim were a work wear staple for miners, workers and cowboys. Most people might think that denim is much heavier and sturdier than cotton, but what you really need to know is that denim is actually made from cotton. It is a durable cotton, mainly used to make jeans. To create denim, the weft passes beneath two or more warped threads. The weaving process produces the typical diagonal ribbing of denim. That’s why denim is much thicker and stronger than cotton.

Needles that Work Best with Denim

Choosing the right needle for your sewing machine is just as important as the machine itself. There are different size and types of needles, so it’s quite important to choose one that fit your fabric. Keep in mind that one size does not fit all types of fabrics. For example, a small needle will often break when you will sew thick and bulky fabrics like denim, jeans and leather. Therefore, you have to change the standard needle and opt for a larger needle that can pierce through layers of heavy fabric. When it comes to sewing machine needles, there is a great rule to keep in mind: the heavier the material the larger needle size and the thinner the material the smaller needle size. However, if you are going to use the machine for denim, remember that out on the market there are needles that are specially made for jeans and denim. These types of needles are a bit different than the standard needles. Thanks to their sharp and long blade, denim needles can go through the fabric when it is flat. No matter what sewing machine you choose, the needle size is very important. Take a look at the table below and find the needle that works best with your fabric.

Fabric Needle Type Needle Size
Sheer to lightweight Regular Point 9/70 or 11/80
Lightweight Regular Point 11/80
Medium-weight Regular Point 14/90
Medium to Heavy-weight Regular Point 16/100 or 18/110
Denim and Canvas Regular Point 16/100 or 18/110
Sheer to Lightweight Knits Ball Point 10/70 or 12/80
Medium to Heavy-weight Knits Ball Point 14/90
Specialty Fabrics Wedge Point 14/90 or 16/100

What to Look for ?

When it comes to denim, it’s important to know that not all heavy-duty machines are able to handle thicker fabrics like denim or leather. However, most of them can help you finish even the most complicated projects. Therefore, when you go shopping for a denim machine, it’s recommended to choose a model that includes some of the following features.

  • Denim needle

    Denim needles are mainly designed to stitch through the thick fabrics without breaking. They are thicker than standard needles and are able to penetrate sturdy materials like denim and leather. These types of needles are not very resistant, so you should lubricate the needle to help it pass through the fabric. Some models come with a dedicated denim needle, while others don’t have this option. However, if your machine doesn’t have a denim needle, you will need to purchase it separately.

  • High presser foot lifter

    The high presser foot lifter is one of the most important options a sewing machine should have. It is extremely useful, especially if you are thinking about sewing denim. When working with heavy fabrics, you will want to use your both hands, so it’s a bit uncomfortable to use your hands lifting the presser foot. Therefore, if you are looking for a sewing machine, choose a model that comes with a high presser foot lifter to do the hard work for you.

  • Strong motor

    Most heavy-duty machines for denim will be equipped with a strong motor which ensures that it can force the needle through the fabric without breaking up the jeans. Some low-cost machines come with weak motors with plastic gears, so they won’t be able to handle multiple layers of fabric without giving up the ghost.

  • Metal frame

    When shopping for a denim sewing machine, choose a model that has a metal interior frame. It is more durable than the plastic one and gives the unit a longer lifespan. Metal, as opposed to plastic, requires a strong motor that can handle thicker fabrics like denim or leather.

  • Stitch length

    As you probably know, each sewing machine has a maximum stitch length and width. If your tailoring machine has the option for variable stitch length, make sure you choose the longer length stitches. With this stitch length, the needle will efficiently penetrate heavy fabrics without breaking them. In order to select the stitch length much easier, there are some quality machines that will allow you to use a dial. As such, when go shopping, choose a model that allows you to do all these tasks.
