1.	5. Read the passage and prepare a flow chart based on it:Rayon is a man-made fibre. It is a reconstituted natural fibre-cellulose. Rayon ismade by dissolving cellulose in a solution of sodium hydroxide or caustic soda.The cellulose is obtained from shredded wood pulp. The dissolved cellulose isformed into threads by forcing it through a spinneret in a setting bath of dilutesulphuric acid. The threads are drawn from the setting bath, wound on a reel,washed, then dried on a heated roller and finally wound onto a bobbin.
