Abstract
Provided with a loess-containing fiber and its manufacturing method wherein the fiber contains loess that generates far-infrared rays and has antibiotic and disinfectant properties, the method including the steps of melting a polymer to form a melt polymer, firing loess in a firing furnace, grinding the fired loess into particles having a specified size by means of a mill, and admixing the powder of the ground loess with the melt polymer in a mixer.
Claims5
A method of manufacturing a loess-containing fiber, comprising the steps of:
- a) forming a melt polymer by melting a polymer in a melting furnace and maintaining the melt polymer in a liquid state;
- b) firing loess in a firing furnace in order to mix the loess with the melt polymer;
- c) grinding the fired loess into particles having a specified size by means of a mill;
- d) admixing the powder of the ground loess with the melt polymer in a mixer;
- and
- e) extrusive-spinning the mixture of the loess and the melt polymer to produce a fiber.
