Preparation for application onto a cellulosic fabric or textile material and textile articles comprising same

Abstract

A preparation for application onto a cellulosic fabric or textile material includes a blended mixture of wool particles or wool powder, and a binding agent. The functional additive is carried by the wool particles. The wool particles or wool powder is preferably of macrofibril size or below. Such a preparation exhibits exceptional functional additive-carrying and retention ability which enhances the durability of functional enhancements of a cellulosic fabric material. In another embodiment, the preparation includes a mixture of powdered bamboo fibre, carrier agents, and binding agents. Preferably, the non-charcoal fibrous bamboo powder is nano-sized having an ultrafine particle size, e.g., 1 μm or below. Fabric materials treated with ultrafine bamboo fibre powder have good moisture management properties.
