ZERO-AOX SHRINKPROOFING TREATMENT FOR WOOL TOP AND FABRIC .2. COLLAGEN RESIN APPLICATION

The halogen-free shrinkproofing resin presented in this work is based on the natural protein collagen and a crosslinking agent, which provid es a covalent linkage between the wool and the resin (collagen). Glyci dylacrylate and the trifunctional epoxide Araldit PT 810 are applied a s crosslinkers. Almost complete shrink resistance of wool fabric and t op is achieved using the collagen/Araldit resin with plasma pretreated material. In combination with the oxidative plasma treatment describe d in Part I, the additive collagen treatment appears to be an effectiv e substitute for the chlorine/Hercosett process.
