Description

technical field [0001] The invention relates to the field of composite fibers, in particular to a superabsorbent ES composite fiber and a preparation method thereof. Background technique [0002] The cross-section of the same fiber has two or more kinds of immiscible polymers at the same time, that is, composite fiber, which belongs to a kind of physically modified fiber. Nowadays, there are more and more types of composite technology and composite fibers. Through composite fiber manufacturing technology, modified fibers containing two polymer properties can be obtained, such as bicomponent fibers and ultrafine fibers. ES composite fiber is a kind of composite fiber. [0003] The ES of ES fiber is the abbreviation of "Ethylene-Propylene Side By Side" in English, and it is a kind of eye-catching polyolefin fiber. As a new type of heat-bonding composite fiber, ES fiber has won high praise in the world. ES fiber belongs to the key development varieties of my country's textil...
