The Modification of Wool by Certain Organic Sorbates

Abstract

The pleat retention, load—extension behavior, bursting strength, hygral expansion, felting rate, abrasion resistance, wrinkle recovery, and bending length of fabrics treated with additives of the type described in Part I have been investigated. Those additives of the anionic detergent type which contain more than 50% alkyl chain per molecule bring about the least improvement in pleat retention and the greatest modification in the wrinkle recovery and extensional properties of the fabric, whereas those which are naphthalene sulfonic acid derivatives accelerate photochemical decomposition of the fabric. The treatments are fast to dry-cleaning and to water but not to alkali. All the additives examined decrease the hygral expansion and felting rate of the fabric and in crease its resistance to abrasion.
