Title:
A TREATED YARN AND METHODS FOR MAKING SAME
Document Type and Number:
WIPO Patent Application WO2003000979
Kind Code:
A3
Abstract:
The present invention relates to methods and apparatuses for treating yarn to enhance the performance characteristics, such as the odor adsorption capacity, of the yarn while retaining the physical properties, such as hand and feel, associated with the yarn. Methods for treating the yarn involve incorporating solid particles such as activated carbon into the yarn using an air dispersion technique or a padding technique. The air dispersion technique disperses the solid particles over the yarn in a controlled air stream. The padding technique incorporates solid particles into the yarn when the yarn passes through a bath of solid particles. The yarn treating method may apply a binding agent to the yarn. The binding agent binds the solid particles to the yarn without inhibiting the performance characteristics of the solid particles. The yarn treating method further includes curing the binding agent to permanently attach the solid particles to the yarn.
