Composite fiber capable of emitting far infrared heat energy and preparation method thereof

Abstract

The invention relates to composite fiber which can send out far infrared heat energy and a method for preparing the composite fiber. The method is characterized in that the method comprises: firstly, sufficiently dipping fiber or fiber products into inorganic organic combined composite solution, wherein the inorganic organic combined composite solution is composed of active water-soluble ion typepolyurethane, germanium, silane coupling agent, thickener and soft water, wherein the weight content ratio of the active water-soluble ion type polyurethane is 6-15%, the weight content ratio of the germanium is 3-15%, the weight content ratio of the silane coupling agent is 0.20-0.40%, the weight content ratio of the thickener is 0.50-0.05%, and the weight content ratio of the soft water is 70-90%, then, taking out the fiber or the fiber products, drying until the liquid hold-up rate is 80-90%, drying under the temperature of 100DEG C, enabling the liquid rate to be less than 10%, then crossing and curing under the temperature of 110-140DEG C, and obtaining the final product. The product is composed of natural or chemical fiber and germanium which is dispersed in the fiber, wherein the weight content of the germanium is bigger than 200PPM. Compared with an existing technique, the invention has the advantages that both enough infrared heat energy and far infrared heat energy can be sent out under normal temperature and normal pressure.

Description

Technical field: [0001] The invention relates to a functional composite fiber and its manufacturing method Background technique: [0002] Current medical far-infrared fiber products generally contain tourmaline components, (tourmaline, a borosilicate mineral commonly known as "tourmaline" is a natural multi-element non-metallic mineral. Its chemical composition is boron (B ), magnesium (MG), aluminum (AL), silicate. It has unique physical and chemical properties such as piezoelectricity and pyroelectricity, has electromagnetic radiation in the far-infrared band, produces negative oxygen ions, and has antibacterial and deodorizing functions) , this kind of fiber that can emit far-infrared heat can only cause the potential difference of the tourmaline crystal to generate far-infrared heat and ionize the surrounding air that is generated in the air only when the temperature and pressure change are higher than normal temperature and normal pressure. Negative oxygen ions. In th...
