Fiber materials having improved qualities required for clothes and method of improving the same

Abstract

Fiber materials (for example, yarns, knitted goods and woven goods) are provided which sustain texture characteristics of a natural fiber such as silk, are effectively prevented from yellowing over time due to light or sweat, are less contaminated with a residual toxic gas, and are effectively prevented from worsening in warmth retention and strength over time, but which can be produced at a lower cost. More specifically, the fiber materials having improved qualities required for clothes are obtained by bringing a chemical fiber containing 0.01 to 5.0% by weight of titanium oxide together with a natural fiber.
