Abstract

The invention relates to radiation resistant polyester fibers with a microphase separation structure and a preparation method thereof. The polyester fibers comprise the following components by mass percent: 1-30% of BaSO4 supported activated carbon resins, 1-5% of nanocomposite antibacterial fiber master batches and the balance of fiber chips. The preparation method comprises the following steps: mixing the BaSO4 supported activated carbon resins, the nanocomposite antibacterial fiber master batches and the fiber chips and then carrying out melt spinning. The polyester fibers and the preparation method have the following beneficial effects: the polyester fibers have good spinnability, light weight and good comfort, have the functions of resistance to negative ions and far infrared emission and health care, can be applied to radiation resistant clothing and radiation resistant reinforced materials and have broad application prospects; and the preparation method is simple, has the advantages of lower cost and low requirement for equipment and is suitable for mass production.

Description

technical field [0001] The invention belongs to the field of polyester fiber and its preparation, in particular to a radiation-proof polyester fiber with micro-phase separation and its preparation method. 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. With the emergence and wide application of various high-radiation equipment, the research on radiation-proof materials has attracted widespread attention. At present, for radiation-proof fibers, most of them are heavy metal wire fibers, which will inevitably bring about many shortcomings such as insufficient protection performance, heavy quality, poor wearing comfort, and poor dyeability. Therefore, the development of a fiber with radiation protection and health care functions not only meet...
