WOOL PRE-TREATMENT METHOD

摘要

Keratin-containing fabric is treated by exposing it to a fluorine-containing gas for a relatively short time, for example 60 seconds or substantially less, by passing the fabric continuously through an atmosphere containing fluorine gas. The fluorine content of the gas to which the fabric is exposed can be relatively low, for example 3 %. The fluorinated fabric may be treated with a polymer such as an amino polysiloxane, and when so treated is protected against shrinkage and maintains good fabric mechanical properties.
