| titleOfInvention | Method for producing polytrimethylene terephthalate resin |
| abstract | The invention relates to a PTT resin, which has a number average molecular weight of 20,000 or more and a polydispersity index, indicating a dispersibility of a molecular weight, of 1.3-2.7, a method of producing the same, and a PTT fiber produced using the same. The PTT resin is advantageous in that it has a uniform molecular weight distribution, and thus, an increase of a pack pressure is suppressed, a pack change cycle and a wiping cycle are lengthened in the spinning process of a PTT fiber. Thereby, the productivity of the PTT fiber is increased, the uniformity ratio of a grey yarn produced using the PTT fiber is increased, and the physical properties of the grey yarn are improved. Furthermore, the PTT fiber has a relatively high tenacity due to its relatively high molecular weight, and thus, the intrinsic and desirable physical properties of the PTT fiber, such as flexibility, elastic recovery, softness, resistance to chemicals, are scarcely reduced during subsequent processes, such as a false twisting process, a drawing process, a knitting process, and a weaving process. Additionally, the workability of the PTT fiber is improved in the subsequence processes, bringing about the reduction of the production costs the PTT fiber regardless of its uses, such as clothes or industrial fibers. |
