Problems solved by technology

[0003] At present, most of the radiation-proof fibers are heavy metal fibers, which will inevitably bring many shortcomings such as heavy weight, poor softness, poor comfort, and poor dyeability; The fiber with health care function has not been developed yet, so the development of a fiber with radiation protection and health care function not only meets the current development trend of radiation protection fiber, but also meets the requirements of fiber differentiation and multifunctionality

Abstract

The invention relates to a radiation-proof polyester fiber for emitting negative ions and far infrared rays and a preparation method thereof. The polyester fiber has the following raw materials according to weight percentages: 0.1-10% of active carbon loaded with BaSO4, 0.1-3% of nanometer silver anti-bacterial agent, 0.1-3% of far infrared-emitting agent, and the balance of fiber slice. The polyester fiber is soft, light and radiation-proof, and has the health functions of emitting the negative ions, the far infrared rays, and the like; the polyester fiber has wide application prospect; and the preparation method of the polyester fiber is simple in operation, has lower cost and low equipment requirement, and is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of polyester fiber and its preparation, in particular to a polyester fiber with anti-radiation, negative ion and far-infrared emission and a preparation method thereof. Background technique [0002] Radiation has been listed by the World Health Organization as the fourth largest source of environmental pollution after water, air, and noise, and has become an invisible "killer" that endangers human health. Radiation protection has become a top priority. Anti-radiation materials have become a major topic in materials science today. With the emergence and wide application of various high-radiation equipment, the research on anti-radiation materials has attracted widespread attention. The use of high radiation sources in various medical testing equipment is becoming more and more common. In order to protect the health of medical staff, radiation-proof fibers and their fabrics are also an indispensable material. [0003] ...
