Abstract
A polyamide 56 resin, a fiber, a preparation method therefor and use thereof are provided. The method for preparing the polyamide 56 resin comprises a step of preparing the polyamide 56 resin from monomers by a polymerization reaction, wherein the polyamide 56 resin contains titanium dioxide, and the titanium dioxide is added during polymerization. The method for preparing the polyamide 56 resin in an embodiment can effectively prevent problems such as monofilament breakage and poor dyeing performance in a subsequent spinning process. In addition, the method is simple and easy to operate, and has a low production cost.
