The aim of this paper is to review KORUS FTA Rules of Origin. Although there are some differences in terms of structure and contents, KORUS FTA Rules of Origin is not much different from the other FTA's texts that Korea has already concluded. Textile and Apparel chapter is also separately specified. For textile and apparel goods, Korea and the US agreed to adopt 'yam-forward rule', allowing exceptions for certain goods. Both sides also agreed to introduce procedures for permitting to use non-Party's materials when fibers ryarns rfabrics are not available in commercial quantities. Overall evaluation on KORUS FTA is considered to be positive. Economically, KORUS FTA is expected to provide good opportunities for Korean companies to access the US market. Politically, Korea and the US can take advantage of KORUS FTA to reinforce the relationship between the two countries.

The newly developed cone drum twister is one of the outer surface contacting friction-twisting devices in false-twist texturing. An investigation of the drag angle for the newly developed cone drum twister texturing mechanism is reported. An analysis is given from which equations can be derived that relate to the conical angle of cone drum, wrapping angle, drag angle, and yam helix angle. Theoretical values of drag angle are calculated and discussed. It is shown that, as the helix angle and the projected wrapping angle increases, the drag angle also increases slowly until the helix angle of $40^{\circ}$ but after the helix angle of $40^{\circ}$ the drag angle increases rapidly. Furthermore the higher the projected wrapping angle and conical angle, the higher the drag angle of friction surface.
