RAYON is made from wood. Rayon is the oldest manufactured fiber, having been in production since the 1880s in France, where it was originally developed as a cheap alternative to silk. Silkworms, sheep, beaver, buffalo deer, and even palm leaves are just some of the natural resources that have been used to meet these needs. Vinyon (1939) Synthetic fibres are the fibres made by humans by the chemical synthesis and not derived directly from the living organisms. Synthetic fibres are of four types, namely: However, synthetic fibre melt on heating. When choosing feminine hygiene products, use organic cotton tampons like Natracare (as recommended in our e-book Label Lessons), or products like the Diva Cup, a silicone reusable product that is inserted into the vagina like a tampon.

For eg., polyester is a wrinkle-free fibre obtained from coal and petroleum and is used for making jackets, raincoats and ropes. Cuprammonium rayon fibers are made from cellulose dissolved in a cuprammonium solution (copper and ammonia). It smells like burning paper and leaves soft, gray ash. A 2005 FDA study found "detectable levels of dioxin in seven brands of tampons," and that included at least one brand that was promoted as 100 percent cotton. Viscose and Rayon are similar because viscose fabric is considered as being a type of rayon, but it is not identical to it. Regular tampon use would be considered repeated exposure. The salt is heated and dehydrated to form the polymer, which is melted and spun to create the nylon fiber. According to the EPA, dioxin exposure causes cancer in lab animals and poses a high risk for humans as well. Synthetic fibres are of four types, namely: Rayon; Nylon; Polyester; Acrylic; Rayon. The process to manufacture rayon begins with the plants that make it possible, such as wood. As opposed to natural fibres, filament production in synthetic fibres is brought about by the spinning process which is either wet or dry.
