It is made up of many glucose monomers, which is food for moths and moulds. Whereas acrylic wool is synthetic fibre, manufactured from petroleum, which is moth-resistant.
2. Yes, 'manufacturing synthetic fibres is actually helping conservation of forests'. As synthetic fibres are obtained from petrochemicals, they have very well substituted the use of natural fibres like cotton, silk, wool and jute which are obtained from plants and animals.
