What is Denim? All about Denim

In short: denim is the fabric from which jeans are made. What cannot be explained so briefly is what denim actually is. It is a complex and unique fabric with a rich historical and cultural heritage. What sets denim apart from other fabrics is its adaptability and versatility; there are endless ways to dye, fade, embellish and customize it, with each method creating a unique result.
It is one of the most popular and durable fabrics in the world. Initially, the work clothes for workers were made from it. Traditionally, denim was a fabric made from cotton in a twill weave and dyed with indigo. Today, there are numerous types of jeans on the market. In addition, different surface finishes are used, such as coating and printing. These increase functionality and aesthetics and add value to denim.

The History of Denim

The origin of denim was in 1600, in the south of France. A robust twill weave called "serge de Nîmes" (Nîmes twill) evolved into the English word "denim". However, there are some doubts about the origin of the word. Some believe that it comes from another French fabric called "Nim". Adding to the confusion, both fabrics - serge de Nîmes and Nim - were originally made from wool or a blend of wool and silk, unlike today's denim, which is cotton. We can also find a similar fabric in Genoa, Italy, called "Bleu de Gênes" (blue of Genoa). It was a durable and coarse fabric used by manual workers. In the early 1700s, textile mills in the United States began to make the same twill weave as European denim. However, they were using local cotton as it was easier to get.

Why is denim blue?

In 1800, they were made in two colors: blue and brown. The blue dye with which the fabric was dyed, called Indigo, was imported from India and became popular in the textile trade. The blue color had a peculiarity: it dyed only the transverse threads. After each wash, the pants became softer, gradually taking on the body's shape. The brown dye did not give such an effect: the clothes remained stiff, so buyers liked them less.

There is a legend about the origin of that color: it is said that in the hold of a ship going to the US, along with the denim ordered by Levi Strauss, barrels with blue paint were carried. During a storm, they turned over and soiled some rolls of fabric. Despite the failure, the businessman decided to sell the goods. And it turned out that people liked the fabric of that color even more than usual. Since then, they began to color all the pants. What is certainly not a myth is that workers wore durable blue work clothes provided by their employers, as blue is the cheapest color to produce. This is why the term "blue-collar" refers to someone who does manual labor.

How is denim made?

For Sumissura denim, the fiber is first cleaned of the dirt from being outside. Once clean, we will mix it with more fibers, in this case, with more cotton fiber, but it can also be mixed with polyester, polyamide, viscose, etc. For the thread to form, we will have to twist the fibers and stretch them to obtain the resistance we want from the thread. The thickness and the length are decided by us, depending on the coil we will use. From these reels, a much larger width reel is passed, where all the threads that will form the warp of the Denim will go, one next to the other. Once wound on the beam, the threads will pass through a bench, where they are dyed with indigo. Once the dyeing process is finished, they are rewound on the beam. From there, a treatment is carried out called gluing. A protective layer is given to resist abrasion when forming the fabric. We will form the fabric, and for that, we take the warp beam to the loom, where it will be intertwined, with a twill weave, with the weft thread. Once the fabric is finished, it will be given a finish according to the use we want to give it. Finally, it is packed, on a roll, or flat in a folder.

Types of Denim Fabrics

Denim, a cornerstone in the world of fabrics, is not just a single entity but a spectacular canvas of variety and style. In this exploration, we delve into the different types of denim fabrics, each with its unique charm and functionality.

Raw Denim: Often referred to as 'dry denim', raw denim is the purest form of denim, untouched by washing or distressing processes. Its key feature is the way it conforms to the wearer's body over time, creating personalized fading patterns and whiskering. This type of denim is prized for its longevity and the beautiful patina it develops with wear. Raw denim is perfect for those who value a custom-fit and a personal touch in their garments.
Selvedge Denim: The term 'selvedge' comes from 'self-edge', referring to the clean, natural edge of the fabric that prevents unraveling. Selvedge denim is known for its high quality and durability, woven on traditional shuttle looms. It is often recognized by the iconic red or white edge visible when the jeans are cuffed. This denim is a favorite among denim aficionados for its classic look and robust feel.
Stretch Denim: Infused with a small percentage of elastane or spandex, stretch denim offers flexibility and comfort, making it a popular choice for everyday wear. It retains the classic denim appearance but provides more ease of movement, ideal for those who prioritize comfort without compromising on style.
Acid-Washed Denim: Known for its distinctive faded, almost marbled appearance, acid-washed denim undergoes a chemical process involving chlorine and pumice stones. This type of denim stands out for its edgy, vintage look, often associated with the rebellious styles of the 1980s. It's a go-to for fashion enthusiasts who love to make a bold statement.

Each type of denim fabric offers its own set of benefits, from the custom-fit allure of raw denim to the comfortable give of stretch denim. Whether you’re looking for durability, comfort, or a specific style statement, there’s a type of denim to suit your needs. Understanding these variations helps in making an informed choice and appreciating the diverse world of denim.

The Art of Indigo: The Journey from Traditional Dye to Modern Mastery

The indigo dye, with its deep blue allure, has long been synonymous with the soul of denim, imparting jeans with their iconic hue that has captivated hearts and styles across generations. This journey of color, steeped in tradition yet constantly evolving, marries the ancient art of dyeing with contemporary innovations, giving birth to an array of techniques that celebrate both heritage and modernity in the realm of denim.

The Roots of Indigo Dyeing

Indigo dyeing, an art form revered for its rich color and depth, finds its origins in nature. Derived from the indigo plant, this natural dye has been used for centuries across various cultures to achieve the coveted blue shade that is both vibrant and lasting. The traditional process of indigo dyeing is a craft in itself, involving:

Fermentation: The indigo leaves are fermented, converting the natural glycosides into the indigo dye.
Dipping: The yarns or fabrics are repeatedly dipped into the dye bath, allowing the indigo to adhere to the fibers.
Oxidation: Between dips, the material is exposed to air, undergoing oxidation that transforms the dye into its distinctive blue hue.

This meticulous process, while time-consuming, is celebrated for the unique characteristics it brings to the fabric, including the variation in shades and the personal patina that develops with wear.

The Evolution to Contemporary Techniques

As the fashion industry strides forward, the method of applying indigo to denim has embraced technological advancements and sustainable practices, broadening the spectrum of denim aesthetics and functionalities. Innovations include:

Synthetic Indigo: While natural indigo remains prized, the development of synthetic indigo has allowed for greater consistency and accessibility in dyeing processes.
Foam Dyeing: A modern technique that reduces water usage, foam dyeing involves applying indigo in a foam form, offering an eco-friendly alternative to traditional methods.
Laser Fading: In place of manual fading techniques, lasers are now used to achieve precise patterns and fades, providing a controlled and customizable approach to denim finishing.
