d) There is more than one way to make rayon. The most common way – and the one widely used for bamboo – is called the viscose process.
b) In this process, cellulose material (such as bamboo) is dissolved in a strong solvent to make a thick, viscous solution that is forced through a spinneret into a quenching solution where strands solidify into fiber.
c) This is sometimes called hydrolysis alkalization or solution spinning because the fiber is “spun” in a chemical solution.
a) The solvent used for this process is carbon disulfide, a toxic chemical that is a known human reproductive hazard. It can endanger factory workers and pollute the environment via air emissions and wastewater.
