    Abstract: PROBLEM TO BE SOLVED: To obtain a polyester composite finished yarn maintaining tension, rigidity and repulsion, providing a woven fabric and a knitted fabrics with new grain tone and uneven surface feeling and to provide a method for producing the finished yarn. SOLUTION: This composite finished yarn comprises at least two kinds of polyester multifilaments A and B having false twisting crimp. The multifilament A comprises a single filament partially having an undrawn part, has a shrinkage percentage in hot water smaller than that of the other multifilament B. Both the multifilaments A and B have difference in dyeing in the lengthwise direction of the multifilaments.

    Abstract: PROBLEM TO BE SOLVED: To precisely feed a fiber yarn to a specific position in a nozzle without interfering plural yarns. SOLUTION: This guide for nozzle is arranged near a nozzle inlet and independently feeds at least two or more kinds of fiber yarns to the interior of the nozzle and constituted of a slit-like yarn guide member (A) and a separating body (B) fixed to the yarn guide member (A) and each independently separating plural fiber yarns and has a spare (S) capable of introducing fiber yarn having substantially limitless length into a yarn guide part in a part of boundary between the yarn guide member (A) and the separating body (B).

    Abstract: PROBLEM TO BE SOLVED: To provide a nozzle for a chemically synthetic fiber, capable of mixing and processing the fiber stably even in a high overfeeding ratio. SOLUTION: This nozzle for the chemically synthetic fiber has a yarn thread- introducing opening Y, a yarn thread-discharging opening Ye, and a fluid- injecting orifice I positioned between the yarn thread-introducing opening Y and the yarn thread-discharging opening Ye, and is so structured that a fluid from the fluid-injecting orifice I is injected to yarn threads of the chemically synthetic fiber which are introduced from the yarn thread-introducing opening Y and travel, so as to mix the yarn threads with each other, wherein a separator C is located between the yarn thread-introducing opening Y and the fluid- injecting orifice I, so that the introduced yarn threads are separated from each other.

    Abstract: PROBLEM TO BE SOLVED: To obtain a false twist textured yarn having fine crepes, a soft touch feeling, excellent drapeability, stretchability and even dimensional stability, and to provide a method for producing the false twist textured yarn. SOLUTION: This false twist textured yarn is characterized in that the yarn is composed of polytrimethylene terephthalate and subjected to false twist texturing and has primarily twisted and untwisted crimps and 200-1,000 turns/m real twists.

    Abstract: PURPOSE: To provide an interlacing nozzle allowing a large overfeed ratio between core and sheath, giving a yarn having excellent uniformity with dispersed loops and capable of adding much interlaced parts to get a yarn having excellent shape durability of loops. CONSTITUTION: In an interlacing nozzle having a capillary-like yarn guiding part and at least one fluid jetting hole Ai opened into the yarn guiding part, this interlacing nozzle is characterized by the followings: (i) the yarn guiding part is divided into at least one yarn introducing part Yi and a fluid-treating part Yt adjacent to the Yi, (ii) an opening area ratio B/A satisfies 1.5

    Abstract: PROBLEM TO BE SOLVED: To provide a fused false-twist textured yarn capable of giving fabric products suitable as a material for clothing for both spring and summer seasons having crisp feeling and soft touch feeling as well, also having softness, drape tendency and sufficient fusing strength, despite comprising partially fused conjugate fiber composed of a polyester polymer (A) and a low-melting polymer (B) with a melting point >=10 deg.C lower than that of the polymer (A), and to provide a method for producing the textured yarn. SOLUTION: This fused false-twist textured yarn is such that conjugate fibers each composed of a polymer (A) consisting substantially of a polyester and a low-melting polymer (B) with a melting point >=10 deg.C lower than that of the polymer (A) are partially fused, and is characterized in that the low- melting polymer (B) is intermittently located irregularly and in the yarn longitudinal direction on the surface of the filament.
