Abstract
A method for manufacturing a flame-retardant bulky fiber without a flame retardant on a fully-drawn yarn (FDY) machine is provided. The flame-retardant bulky fiber is formed by winding a plurality of spiral yarns arranged in the same direction; and the yarns are polyester yarns with a fineness of 0.52 DPF to 80 DPF. The method includes the following steps: slicing and drying a polyester masterbatch; spinning through a spinning die, and cooling by side blowing; cooling and oiling; drawing by a first hot roller; drawing and shaping by a second hot roller; and winding. The present disclosure can manufacture a flame-retardant bulky fiber on an FDY machine, which has the same effect as drawn textured yarn (DTY) manufactured by a texturing machine. Moreover, without being added with any chemical flame retardant, the flame-retardant bulky fiber of the present disclosure can reach the flame-retardant standard of home textiles.
