The Development of Washable Non-Iron Effects in Pure Wool Fabrics

Abstract

The use of reducing agents for setting wool has been extended to give washable non-iron effects on pure wool fabrics. Initially this was accomplished by applying the Si-Ro-Set process to garments made from shrinkproofed wool. This led to flat setting of fabrics in the mill by applying a dilute solution of a reducing agent to the fabric fol lowed by immediate steaming on a blowing machine. When preceded by shrinkproofing, this method of setting gives excellent washable non-iron effects on pure wool fabrics. Garments made from fabric treated in this way showed satisfactory laundering and wear performance in practical trials.
