METHOD OF REDUCING THE TENDENCY OF A LYOCELL FABRIC TO PRIMARY FIBRILLATION

摘要

The tendency of a lyocell fabric to primary fibrillation after dyeing and washing is reduced by contacting the fabric, before dyeing, at elevated temperature with an aqueous solution of an oxidising agent such as a hypochlorite or hydrogen peroxide. Depending on the nature and concentration of the oxidising agent, the fabric produced may have substantially no fibrillation after subsequent dyeing and washing or may develop a peach-skin hand after subsequent dyeing and washing.
