The Origin of Rayon Fabric

Although early steps in the production of rayon fabric were made in the mid-19th century, it was not until the late 19th century that a more conventional form of rayon was developed. Originally referred to as Chardonett silk, this form of rayon was commercialized in 1911.

Commercialization was catalyzed by the invention of the viscose process, which gave birth to viscose rayon. As the years went by, more technologies were born, giving rise to other types of rayon including Lyocell rayon and High Wet Modulus Rayon. These advanced rayon forms are still in use up to date.

Advantages of Rayon Fabric

  • Drapability: Owing to the slinky nature of the semi-synthetic fibers utilized to produce rayon, it is often deployed in the manufacturing of draping or loose clothes.

Rayon Fabric Manufacturing

For the elegant rayon fabric material to be born, numerous ingredients must be amassed and taken through a series of chemical processes.

In the case of rayon, natural cellulose garnered from plant-based sources, especially pine and bamboo, is the main ingredient. The conversion of raw cellulose into shiny rayon fabric can be accomplished using numerous methods.

Viscose Process

The viscose process has been in use since rayon fabric was commercialized. Essentially, this process generates viscose by transfiguring cellulose from plants. This is accomplished in the following steps:

Step 1: Cellulose Extraction

Cellulose is the primary ingredient in rayon manufacturing. It is typically sourced from wood pulps drawn from bamboo, eucalyptus, or other natural sources. This can be achieved using chemical or mechanical means. The extracted cellulose is then processed using caustic soda and carbon disulfide to generate cellulose xanthate.

Step 2: Viscose Generation

Subsequently, the cellulose xanthate generated after the cellulose has been chemically treated is preserved for a while or aged. This results in the formation of a viscous liquid that is yellow in color. This is referred to as the viscose.

Step 3: Spinning

The resulting viscous liquid is then squeezed into a coagulating bath, where it is transformed into rayon filaments. The coagulating bath often utilizes sulfuric acid to congeal the viscose.

Step 4: Excess Alkali Removal

With the rayon strands well-formed, a neutralization process is initiated. This process involves washing the rayon threads to dislodge unwanted chemicals amassed in the previous steps. To dislodge the surplus alkali from the filaments, weaker acids may be deployed.

Step 5: Ripening

For elevated tensile strength, the rayon fabric strands generated are further treated using distinct chemicals.

Step 6: Cutting and Drying

The post-treated rayon filaments are then subjected to regulated heat to flush out unwanted moisture. They are subsequently subdivided into smaller pieces in adherence to the design specifications. The end product is high-quality rayon fabric.
