What is Rayon?<\/strong><\/h2>\n\n\n\n

When talking about fabrics, \u2018rayon\u2019 is not an unheard name. I am sure some of you have clothes, accessories, or homeware items made of this material. You might be wondering what is rayon? In a nutshell, it\u2019s a man-made fiber and yet, it\u2019s not one hundred percent synthetic. Intrigued? Read on to find out what is rayon.<\/p>\n\n\n\n

What is rayon made of?<\/strong><\/h2>\n\n\n\n

Rayon<\/a> is a natural-based material that is made from the cellulose obtained from wood pulp or cotton. It\u2019s a low-cost and convenient fiber to work with and lends itself to diverse uses. There are several grades of rayon that can imitate the look and texture of other natural fibers such as cotton, linen, and silk. The different types of rayon include viscose, modal, and lyocell.<\/p>\n\n\n\n

What is rayon\u2019s origin and history?<\/strong><\/h2>\n\n\n\n

In the 1860s, the French silk industry was in crisis because of a disease affecting the silkworm. Louis Pasteur and Count Hilaire de Chardonnet were studying this problem in hopes of saving the industry. It was during this time that Chardonnet became interested in finding a way to produce artificial silk. In 1885, he patented the first successful method to make fiber from cellulose.<\/p>\n\n\n\n

For the next forty years this material was called artificial or imitation silk. By 1925, it had developed into an industry itself and was named rayon by the Federal Trade Commission (FTC). The term rayon comprised any man-made fiber made from cellulose.<\/p>\n\n\n\n

In 1952, the FTC divided rayon into two categories: fibers consisting of pure cellulose (rayon) and those consisting of a cellulose compound (acetate). By the 1950s, most of the rayon produced was used in industrial and home furnishing products rather than in apparel. Regular rayon (also called viscose rayon) fibers were considered weak in comparison to other fibers used for clothing.<\/p>\n\n\n\n

In 1955, manufacturers began to produce a new type of rayon, high-wet-modulus (HWM) rayon, which was stronger and could be used to make sheets, towels, and apparel. The creation of HWM rayon is considered the most important development in rayon production since its invention in the 1880s. Today rayon is one of the most widely used fabrics and is produced globally.<\/p>\n\n\n\n

How is rayon made?<\/strong><\/h2>\n\n\n\n

Rayon is made from cellulose obtained from wood pulp\u2013usually from pine, spruce, or hemlock trees\u2014and cotton linters, which are residue fibers clinging to cotton seed after the ginning process.<\/p>\n\n\n\n

\"rayon<\/figure><\/div>\n\n\n\n

Viscose rayon is the most common and versatile. It can be blended with man-made or natural fibers and made into fabrics of varying weight and texture. It is also an absorbent, cost-effective, and comfortable fabric to wear.<\/p>\n\n\n\n

High-wet-modulus rayon is a stronger fiber than regular rayon. It is similar to cotton and easy to care for. Fabrics containing modulus rayon can be machine-washed whereas those made of regular rayon need to be dry-cleaned. Whether it is wood pulp or cotton linters, the basic raw material for making rayon must be processed in order to extract and purify the cellulose. The resulting sheets of white, purified cellulose are then treated to form regenerated cellulose filaments. These filaments are then spun into yarns and eventually made into the desired fabric.<\/p>\n\n\n\n

\"rayon<\/figure><\/div>\n\n\n\n

Steps involved<\/em>
\u2022 Sheets of purified cellulose are steeped in sodium hydroxide (caustic soda), which produces sheets of alkali cellulose. These sheets are dried, shredded into crumbs, and then aged in metal containers for 2 to 3 days. The temperature and humidity in the metal containers are carefully controlled.<\/p>\n\n\n\n

\u2022 After aging, the crumbs are combined and churned with liquid carbon disulfide, which turns the mix into orange-colored crumbs. The crumbs are then bathed in caustic soda. This results in a viscose solution that looks and feels like honey. The solution is filtered for impurities and stored in vats to age for 4-5 days.<\/p>\n\n\n\n

\u2022 The viscose solution is next turned into strings of fibers by forcing the liquid through a spinneret into an acid bath. The acid coagulates and solidifies the filaments resulting in regenerated cellulose filaments. Next, the filaments are ready to be spun into yarn.<\/p>\n\n\n\n

\u2022 Once the fibers are sufficiently cured, they are ready for post-treatment chemicals and the various weaving processes needed to produce the fabric. The resulting fabric can then be given a number of finishing treatments. These include calendaring to control smoothness, fire resistance, pre-shrinking, water resistance, and wrinkle resistance.<\/p>\n\n\n\n

What is rayon used for?<\/strong><\/h2>\n\n\n\n

The most common use for rayon is to make various articles of clothing and home-ware, such as blankets, sheets and curtains. Rayon can also be used for making tire cords and surgical products.<\/p>\n\n\n\n

What are the advantages of rayon?<\/strong><\/h2>\n\n\n\n

\u2022 Inexpensive but looks and feels luxurious
\u2022 Some variants of rayon are known for their silk-like feel
\u2022 Drapes well
\u2022 Breathable
\u2022 Blends well with other fibers
\u2022 Dyes easily resulting in beautiful colors<\/p>\n\n\n\n

What are the disadvantages or rayon?<\/strong><\/h2>\n\n\n\n

\u2022 Not a very strong fabric, more so when exposed to light or moisture
\u2022 Can shrink when washed, thus has to be dry-cleaned
\u2022 Can get damaged while ironing
\u2022 Manufacturing method is harmful to the environment and to the safety of the workers if the chemicals used are not handled carefully.<\/p>\n\n\n\n
