Kind Code:
A1
Abstract:
A polyamide 56 resin and fiber, preparation methods therefor and the use thereof. The preparation method for the polyamide 56 resin comprises preparing the polyamide 56 resin from a monomer by means of a polymerization reaction, wherein the polyamide 56 resin contains titanium dioxide, and the titanium dioxide is added during the polymerization reaction process. The preparation method for the polyamide 56 resin in one embodiment can effectively avoid problems such as monofilament breakage and poor dyeing performance in a subsequent spinning process. In addition, the preparation method is simple and easy to operate, and has a low production cost.
