INTERLACE COMBINED FILAMENT CRIMPED YARN AND CARPET

PROBLEM TO BE SOLVED: To provide an interlace combined filament crimped yarn with excellent bulkiness (voluminous feeling, bulky texture) while having sufficient glaze when used for a tufted carpet and others and a carpet using the same.SOLUTION: An interlace combined filament crimped yarn contains a crimped yarn Y1 with triangular cross section and a crimped yarn Y2 with non-triangular cross section. A difference between a crimp expansion rate R2 (%) of the crimped yarn Y2 after boiling water treatment and the crimp expansion rate R1 (%) of the Y1 after boiling water treatment (R2-R1) is 1 to 25 (%).SELECTED DRAWING: Figure 1 【課題】たとえばタフテッドカーペット等に用いられる際に、充分な光沢性を有しつつ、かつ、優れた嵩高性（ボリューム感、風合い等）を備える交絡混繊捲縮糸および該交絡混繊捲縮糸を用いたカーペットを提供する。【解決手段】三角断面を有する捲縮糸Ｙ１と、三角以外の断面を有する捲縮糸Ｙ２とを含み、前記捲縮糸Ｙ２の沸騰水処理後の捲縮伸長率Ｒ２（％）と、前記Ｙ１の沸騰水処理後の捲縮伸長率Ｒ１（％）との差（Ｒ２−Ｒ１）は、１〜２５（％）である、交絡混繊捲縮糸。【選択図】図１
