Title:
TOURMALINE FINE PARTICLE-CONTAINING RAYON FIBER
Document Type and Number:
Japanese Patent JP3297581
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject fiber, capable of releasing a large amount of active electrons and imparting good activating effects to a living body cell by uniformly dispersing tourmaline fine particles with a cellulose xanthate.
SOLUTION: This tourmaline fine particle-containing rayon fiber contains the tourmaline fine particles, uniformly dispersed in a cellulose xanthate and having ≤2.0μm particle diameter in an amount within the range of 0.05-2.0wt.% therein. The fiber is obtained by uniformly dispersing the tourmaline fine particles having ≤2.0μm particle diameter with the cellulose xanthate. The resultant rayon fiber is capable of manifesting high electret properties even with a tourmaline content as low as 0.05-2.0wt.%.
