From (12') (12''), the two types of polymer in the sheath part pass through (13) and (15') provided on the distribution plate (3) to reach the mixing plate (4), and from there the two types of polymers are provided toward the lower surface. The mixed polymers pass through the static kneading elements (15), (15'), and (16) formed by the kneading elements to form a randomly laminated composite state of the two polymers. It reaches the outlet (17) of the kneading element and gradually spreads.The highly soluble polymer in the core passes through (19) of the mixing plate (4) and gradually spreads at the flow divider plate (5). The composite stream flows out from the spinning hole (21) of the spinneret (6), covering the highly soluble polymer, and is discharge-molded and spun as a composite multifilament.

より複合マルチフィラメントとして紡出する。In addition, the two types of polymers used in the present invention are such that the storage portion into which the highly soluble polymer is introduced constitutes the sheath portion and the core portion, respectively, as described above, instead of having separate storage portions.
It is also possible to distribute and split the flow from one reservoir. One side of the divided flow is mixed with a polymer with a low dissolution rate,
It passes through a static kneading element and forms a composite state. - Ten thousand is melted straight, covered with a composite flow, and spun from a spinneret as a composite multifilament.

い。For bath treatment, the concentration, temperature, and bath ratio of the bath agent may be set to such an extent that they do not adversely affect the strength or appearance of the fabric after dissolution. Do this to the extent that it reduces weight. If the weight loss ratio is less than 10% by weight, the laminated filament yarn will not separate into its respective components, and when it is made into a fabric, the desired spun-like warm, light, fluffy and firm texture will not be obtained.
