Title:
PROCESSING OF ARTIFICIAL CELLULOSIC FIBER
Document Type and Number:
Japanese Patent JPH10237766
Kind Code:
A
Abstract:

To manifest high levels of friction mark resistance, color fastness and soft touch feeling by applying an epoxy compound and an acidic catalyst to an artificial cellulosic fiber, heat-treating the resultant fabric, soaping and washing the heat-treated fabric while breaking the fabric.

An epoxy compound such as diethylene glycol diglycidyl ether in an amount of 2-20wt.% and an acidic catalyst such as magnesium borofluoride in an amount of 5-20wt.% based on the concentration of the epoxy compound used are applied to a fabric composed of an artificial cellulosic fiber such as cuprammonium rayon and the resultant fabric is then predried at 80-150°C for 20sec to 2min and further heat-treated at 130-200°C for 5sec to 5min, preferably 140-180°C for 30sec to 3min. The soaping or washing treatment with water is then carried out while breaking the fabric with a jet dyeing machine, etc., and prescribed dyeing processing is subsequently performed.
