Lateral Migration Control During Drying Using Methyl Cellulose

A method developed previously was used to quantitatively assess lateral migration during controlled drying. Methyl cellulose in aqueous solution, which has a unique property of forming a gel when heated, was used to control lateral agent migration during drying of knitted cotton fabrics impregnated with crosslinking reagents. During drying, the reagent solution formed a gel and significantly restricted movement of water and reagents in the capillaries of the fabric. Effects of methyl cellulose concen tration on the rate and extent of migration were evaluated.
