How is Denim Made? the Manufacture of Denim

We try to explain how denim is made in its entirety in this article, from fiber to fabric.

Since 1873, a great pair of jeans has been a necessary item in every wardrobe. We reach for our go-to pair for both comfort and style, whether it’s Friday casual or date night. From unprocessed cotton to the garment hanging in your bedroom closet, denim has a long history.

It typically takes several steps to make denim fabric out of cotton, including harvesting the cotton on the farm, separating the cotton fiber from the seeds, spinning the yarn, dying it, and finally treating the yarn to stop the denim fabric from shrinking.

Discover the answer to the question “How is denim made” by reading on.’

How is Denim Made?

Many processes come in while making denim fabric, these are:

Step One: Getting the Cotton

Cotton, which is the main component of denim, gives it its rigidity and durability. With the exception of Antarctica, cotton is grown almost everywhere on Earth. Almost all denim mills source their cotton from the biggest cotton growers in China, the United States, India, and Pakistan.

The cotton seed needs 140 days to mature into a cotton boll, which can then be harvested by hand or with the aid of a cotton picker machine.

Step Two: Turning Cotton Fibres into Yarns

A type of plant-based fiber called cotton is spun or twisted during the spinning process to create a strong, lengthy, interlocked yarn. The spinning process was carried out manually, by hand, prior to the Industrial Revolution’s invention of the spinning machine.

Both ring spinning and open-ended spinning are currently used to make yarn. Due to its speed and reduced cost, the latter is strongly preferred by most manufacturers.

Step Three: Dyeing the Yarns

An unusual process, dyeing is. Rope dyeing and slasher dyeing are the two methods used to color denim yarns. Both techniques require soaking in dye vats because it allows indigo to penetrate the threads more deeply.

The fabric’s deep blue hue, in particular, is derived from indigo. To create colored or black denim, it is occasionally dyed with sulfur. The dependence on oxygen in the dyeing process of denim makes it special.

The green color characterizes the cotton yarn as it emerges from the first dyeing vat. however, as it dries out when exposed to oxygen, it will eventually turn blue. Oxidation refers to this stage of the procedure.

Only the outer layer of the yarn will be colored during the denim dyeing process, leaving the yarn’s core uncolored. The undyed yarn core will consequently gradually become visible as you wear and wash your denim.

This is the explanation for denim fading. You should take note that wear fading is more noticeable in raw denim than in pre-washed or industrially treated jeans.

Step Four: Weaving the Dyed Yarns

Usually, two yarns are woven together to create denim, which allows the indigo-dyed and un-dyed threads to intertwine. Denim’s distinctive blue front and white back are the result of the interweaving of dyed and undyed threads.

High-end selvedge denim is characterized by the use of shuttle looms, an antiquated weaving technique that is still popular today. These days, the majority of denim mills weave their fabrics on looms without shuttles, enabling producers to make more fabrics in a shorter amount of time.

Due to its raw appearance, the selvedge is popular. Selvedge denim is preferred by denim enthusiasts because it is frequently sold in raw indigo, which enables the wearer to create distinctive fades on the denim. To make the indigo last longer and increase the contrast of the fade, people try not to wash their raw denim.

Denim textiles must pass a strict quality inspection. When the material passes the inspection, it is prepared for shipping to a garment factory where the denim fabric will be made into usable jeans.

Step Five: Designing the Jeans

When creating a pair of jeans, designers always make an effort to take the end user’s lifestyle into consideration. Designers can assess the technical requirements, create a technical sketch, and specify the jeans treatment in a tech pack by posing questions about the utility and target audience.

Step Six: Cutting Jeans Pattern & Sewing the Final Piece

Based on a design pattern that is a part of the garment tech pack, garment makers will cut the denim fabrics from the denim mills into about 20 pieces. In addition, they will get ready the leather patches, labels, zippers, and buttons for sewing.

Step Seven: Laundry Treatments

You’re probably wondering now why the distressed light blue pair you own looks the way it does. In the washing, pre-washing, or pre-distressing treatment stages, a pair of jeans can be made to appear distressed or washed out.

Some people lack the patience to let their jeans deteriorate over time. As a result, businesses like Jeanologia and Tonello exist to develop devices and laundry technologies to dilute indigo to the desired shade for designers.

In addition to fading, some jeans are distressed by stone washing or laser to give the appearance of unmistakable vintage wear and tear over time.

Who Invented Denim?

Denim was first made in 1873 by Levi Strauss and Jacob Davis, who founded the well-known Levi brand. They were inspired by a cotton corduroy fabric called “Serge de Nimes” that originated in Nimes, France.

“Waist overalls,” as jeans were known at the time, were very popular with miners during the They could withstand rough conditions in their pants thanks to the tough twill fabric and metal rivets at stress points during the Gold Rush. Factory workers, farmers, soldiers, mechanics, and carpenters were also big fans.

Denim evolved from its working-class roots over time. The world never looked back after the pants became fashionable thanks to pop culture icons like James Dean and Marilyn Monroe.

History of Denim

Weavers in the French city of Nîmes attempted to imitate the strong, resilient fabric made by weavers in the Italian city of Genoa in the sixteenth century, which led to the creation of the fabric that is now known as denim. The fabric in question was a type of cotton corduroy.

The name of Genoa in French is Gênes, which is possibly where the word “jeans” originated. The French-made fabric was known as serge de Nîmes. Serge, the fabric’s name, and de Nîmes, which is French for “from Nîmes,” made denim; this was the method used to create the first denim fabric.

Final Words: How is Denim Made?

Later, more sophisticated methods utilizing synthetic dye provided an important solution to the problem of how to reduce the cost of denim jeans.

Jeans dyed synthetically were much less expensive to produce than those dyed naturally, and they also had the advantages of permanence and durability.
