  • Patent number: 11846066
    Abstract: The present invention provides an anti-pilling wool fabric with a coating having pilling resistance and resistance to fiber loss from fabric surface. The coating is formed by a coating formulation including at least two diisocyanates, at least two catalyst, a water dispersing agent, a buffer and water, which provides a polycarbodiimide crosslinker reactive to the relative less reactive groups on polypeptide of the wool fabric and promotes crosslinking between polypeptides of the wool fabric under relatively mild processing conditions so as to enhance mechanical strength of the wool fabric whilst no significant effect of the original finish merino wool fabric and/or garment and fiber loss from fabric surface are observed, compared to conventional treatment methods on wool fabric. A corresponding coating formulation and method of fabricating the anti-pilling wool fabric are also provided.
