Under the name viscose a chemical fibre is described, which is manufactured from a naturally-occurring raw material, cellulose. The resulting textile fibres are manufactured as staple fibres. The fibrous material is not thermoplastic and has no welding properties. Service temperatures lie in the middle range and by the use of additives its flammability can be reduced. The mechanical properties are low and resistance against environmental influences, light, acids and alkalis are not high. Absorption properties are high. This material lends itself well to being able to be dyed. Good electrical conductivity leads to low static charging. Special types and mixtures of this material are often used. The material is basically biodegradable and thermically recyclable.
