A method for shrink-proofing a cellulosic fiber textile that involves liquid ammonia treatment, hot water or alkali treatment under tension or under no tension, and with optional resin treatment.

Shrink-proof treatment of cellulosic fiber textile

A method for finishing a cellulose fiber-containing textile fabric comprises treating a cellulose fiber-containing textile fabric with liquid ammonia, applying a resin finishing agent to said fabric, subjecting subsequently to either or both of a hot calendering treatment and a heat treatment, and finally treating the resultant fabric with hot water. The resultant fabric keeps its shape stability including a crease or shrink resistance when washed, without involving any problem on residual formaldehyde.

Method for processing cellulose fiber-containing textile fabrics

Creases are formed in a cellulosic fiber textile by treating the fiber textile with liquid ammonia, creasing the fiber textile, and treating the fiber textile with hot water or alkaline solution substantially simultaneous with or subsequent to the creasing step. Fully durable creases are formed in the cellulosic fiber textile without detracting from strength.

Method for forming durable creases in cellulosic fiber textile

A process for resin finishing textile containing cellulosic fiber comprises the steps of using a resin finishing agent chiefly containing a cellulose-reactive N-methylol compound having two or more functional groups and a reaction catalyst, mainly reacting only one functional group of the cellulose-reactive N-methylol compound with cellulose, water washing, again imparting reaction catalyst, drying, garment making, and heat treating. The process eliminates the conventional postcuring method drawbacks of loss of color fastness and discoloration owing to dye decomposition and formaldehyde increase by unreacted resin and residual reaction catalyst during long storage before heat treatment, and simultaneously achieves high crease-resistant property, shrink resistance, good feeling, excellent pleating property, and anti-puckering property.
