The crimped yarn described in Publication No. 7 is provided with a plurality of melting sections 51, 51', a metering pump 52, 52', and one mouth pack 53, as shown in the schematic process diagram of FIG. One rotary switching valve 54 is provided between the pump 52, 52' and the mouth pack 53, and the melting section 51
．． The polymers having different dyeing abilities melted in step 51' are alternately transferred to the cap pack 53 using a rotary switching valve.
As shown in FIG. 9, the yarn obtained by spinning from 3 to form yarn 55 is a combination of polymer A portion and polymer B portion arranged periodically along the length. .

融状態の熱趙歴が異なり、長さ方向の物理特性が均一と
ならないという欠点を有する。Therefore, the thermal history of the molten state of polymer A and polymer B of the yarn 55 is different when passing through the rotary switching valve and when it is stopped, and the physical properties in the length direction are not uniform. have

ーペットとなした場合、前記ポリマーＡ、Ｂの周期的な
配列に伴ない、染色した場合周期的な色模様となりラン
ダムな色模様にならない。Further, when the obtained yarn 55 is crimped to make a crimped yarn and a carpet without it, due to the periodic arrangement of the polymers A and B, when dyed, it becomes a periodic color pattern and a random pattern. No color pattern.

は略周期的に変化している。The crimped yarn described in the above-mentioned Japanese Patent Publication No. 49-12132 is made by twisting heterochromatic filaments together and twisting them, and due to the twisted yarn, the heterochromatic portions are formed periodically or almost periodically in the length direction. It's changing.
したがって、該巻縮糸を用いたカーペットとして染色し
た場合、周期的な色模様となりランダムな色模様を有す

However, physical properties such as boiling water shrinkage rate, crimp/stretch rate, strength, and elongation are virtually the same, and even if slight differences are found through strict measurement, the difference in dyeing ability is minute. Because they exist extremely irregularly, their physical properties are essentially the same.
