A Closer Look at Nature’s Versatile Fiber

We are continuing our series of articles dedicated to eco-friendly yarns with viscose. At the beginning of my career in knitwear fashion, I didn’t know a lot about yarns and their variety and blends. To be honest I didn’t know anything about viscose, I have knit apparel with viscose, but I thought that viscose was a synthetic fiber and was so wrong! In the next paragraphs, I’m going to tell you more about this beautiful, soft and amazing natural yarn.

In the realm of textile innovation, one fiber stands out for its exceptional versatility and eco-friendly attributes – viscose yarn. Often referred to as “artificial silk” or “regenerated cellulose fiber,” viscose has become a staple in the textile industry, celebrated for its softness, sheen, and breathability. In this article, we delve into the fascinating world of viscose yarn, exploring its origins, manufacturing process, and the myriad applications that make it a favorite among designers and consumers alike.

The Birth of Viscose

Viscose yarn traces its roots back to the late 19th century when French chemist Hilaire de Chardonnet invented the first successful artificial silk known as rayon. However, it was British scientists Charles Cross, Edward Bevan, and Clayton Beadle who later developed the viscose process in the early 20th century, paving the way for the commercial production of this unique fiber. Derived from natural cellulose, usually sourced from wood pulp or bamboo, viscose embodies the perfect blend of natural and synthetic characteristics.

Manufacturing Process

The production of viscose yarn involves several intricate steps, each contributing to the creation of a high-quality, versatile fiber. The process begins with the extraction of cellulose from renewable sources, such as trees or bamboo. After pulping and treating the cellulose with chemicals, a viscous solution is created. This solution is then extruded through spinnerets to form filaments, which are solidified in a bath of chemicals. The resulting yarn is then washed, dried, and spun into the desired thickness, ready to be transformed into a wide array of textile products.

Characteristics of Viscose Yarn

Softness and Drape: Viscose yarn is celebrated for its luxurious softness, closely resembling natural fibers like cotton and silk. Its excellent drape makes it a favorite for creating flowing and elegant garments.

Breathability: Viscose has inherent breathability, allowing air to circulate through the fabric. This makes it an ideal choice for warm-weather clothing, ensuring comfort even on the hottest days.

Sheen and Luster: Viscose yarn possesses a subtle sheen that adds a touch of sophistication to fabrics. This makes it a popular choice for creating garments with a polished and elegant appearance.

Absorbency: Despite being a synthetic fiber, viscose has good absorbent qualities, making it comfortable to wear in various climates.

Applications of Viscose Yarn

Fashion Apparel: Viscose yarn is a go-to choice for creating a wide range of fashion garments, including dresses, blouses, skirts, sweaters and different knit apparel. Its versatility allows designers to achieve various textures and finishes.

Home Textiles: Bedsheets, curtains, and upholstery benefit from the softness and draping qualities of viscose, adding a touch of luxury to home decor.

Accessories: Scarves, shawls, and other accessories made from viscose yarn showcase its elegant drape and sheen.

Blend Possibilities: Viscose blends seamlessly with other fibers, such as cotton, wool, or elastane, enhancing the performance and comfort of the resulting textiles.

When we talk about viscose we have to mention the term “Rayon” and what it means. “Rayon” and “viscose” are terms often used interchangeably, but it’s essential to understand that rayon is a broader category of fibers that includes viscose as one of its subcategories. In other words, viscose is a type of rayon. Let’s delve into the key distinctions between rayon and viscose.

Rayon is a generic term that encompasses a group of manufactured fibers made from natural cellulose, typically derived from wood pulp or other plant-based sources. Rayon is known for its soft and breathable qualities.

Viscose is a specific type of rayon. The term “viscose” is often used to refer to the viscose rayon, which is the most common type of rayon. Viscose is made by the viscose process, involving the conversion of cellulose into a soluble compound that is then spun into fibers.

Manufacturing Process

There are different processes used to produce rayon, including the viscose process (most common), the cuprammonium process, and lyocell process. Each method results in fibers with slightly different characteristics.
Viscose is produced specifically through the viscose process. This involves dissolving cellulose in a solution to create a viscous substance that can be spun into fibers. The fibers are then treated to solidify them.

Chemical Treatment

The term “rayon” encompasses fibers that are produced through various chemical treatments. These treatments may involve the use of carbon disulfide, sodium hydroxide, and sulfuric acid, among other chemicals, depending on the specific manufacturing process.
Viscose is produced by treating cellulose with sodium hydroxide and carbon disulfide to create a viscous solution. The resulting fibers have a soft and silky feel.

Characteristics

Depending on the specific type of rayon, characteristics can vary. Rayon fibers, in general, tend to be soft, breathable, and have a good drape. They can imitate the feel of natural fibers like cotton, silk, or wool.
Viscose, being a type of rayon, shares many of the general characteristics of rayon. It is known for its softness, sheen, and excellent drape. Viscose is often used to create fabrics with a luxurious appearance.

In summary, while “rayon” is a broad term encompassing various types of fibers, “viscose” specifically refers to a type of rayon produced through the viscose process. Both rayon and viscose are widely used in the textile industry, offering a versatile and comfortable alternative to natural fibers.

As consumers become increasingly conscious of their environmental impact, the sustainability of materials used in textiles comes into focus. Viscose yarn, sourced from renewable raw materials, is considered a more eco-friendly option compared to some traditional synthetic fibers. However, it’s important to note that the manufacturing process involves chemicals, and efforts are ongoing to improve the environmental footprint of viscose production.

Viscose yarn has earned its place as a versatile and beloved fiber in the textile industry. Its combination of softness, breathability, and adaptability makes it a favorite among designers and consumers seeking both style and comfort. As sustainability continues to shape consumer choices, viscose’s renewable origins contribute to its enduring appeal in the ever-evolving landscape of textile innovation.
