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 provides a covalent linkage between the wool and the resin (collagen). Glycidylacrylate and the trifunctional epoxide Araldit PT 810 are applied as crosslinkers. Almost complete shrink resistance of wool fabric and top is achieved using the collagen/Araldit resin with plasma pretreated material. In combination with the oxidative plasma treatment described in Part I, the additive collagen treatment appears to be an effective substitute for the chlorine/Hercosett process.
