Filament having ultraviolet ray hiding effect and fabric manufactured from said filament

Abstract

This invention discloses a fiber filament having ultraviolet ray hiding effect and fabric manufactured from said filament. The ultraviolet ray hiding effect of this invention is obtained by adding inorganic titanium dioxide particles having average diameter of less than 100 nm and constituting preferably less than 1 weight % of the total fiber. When fiber filaments of this invention are used in fabric production they constitute preferably over 50% weight of the fabric. thereby producing a fabric with opening rate preferably in excess of 0.7% but preferably less than 25%. The Ultraviolet Protective Factor (UPF) of said fabric is preferably over 40%.
