    Abstract: PROBLEM TO BE SOLVED: To produce polyester textiles constantly excellent in after-processing character and package form while the production condition is varied by specifying the speed of the heat treating godet roller and the textile tension between these godet rollers in direct spinning and drawing process using heating cylinders. SOLUTION: The polyester textile filament cooled and solidified on the cooler 2 is drawn by introducing into the heating cylinder 3 then heat treated by a heat treating apparatus 8 set between a pair of godet rollers 6, 7 and wound-up. The speed of the godet roll satisfies the equation, 63× √d √d [d is speed of a single filament (d); V is take-up speed(m/s)] and the tension of the filament between the godet rollers 6, 7 satisfies the equation, 0.1T

    Abstract: PURPOSE: To obtain a combined filament yarn capable of providing silk-like surface touch in weaving into fabric by combining two kinds of filament groups each having thinness and thickness in the length direction and different in delustering agent content and fineness in a specific state. CONSTITUTION: A filament group A having thinness and thickness in the length direction and containing a delustering agent is combined with a filament group B having thinness and thickness in the length direction and having delustering agent content smaller than that of the filament group A and having average fineness lower by >=1.5 denier than that of the filament group. The resultant combined filament yarn has 2-7% Uster irregularity, 10-30% shrinkage factor by boiling water, 0.04-0.10g/denier continuous shrinkage stress by steam heating and 4.0-12.0% coefficient of variation.

    Abstract: PURPOSE: To provide a thermally fiber-treating device always enabling the optimal thermal treatment of the fiber even when a fiber-producing condition is changed, and suitable, especially when used in a melt-spinning process. CONSTITUTION: The fiber passageway of the main body of a thermally fiber- treating device is disposed in a state capable of being moved in a direction crossing the fiber passageway or in a state capable of being moved in a perpendicular direction. The thermally fiber-treating device disposed on the downstream side of the cooling device of a melt-spinning device is disposed in a state capable of being moved substantially in parallel to the cooling gas blow-off direction of the cooling device and capable of tilting the cooling gas blow-off direction in the perpendicular direction.

    Abstract: PURPOSE:To provide the subject soft polyester conjugated fiber exhibiting a high antistatic property in combination with an elegant gloss and drapability, excellent in workability and suitable for inner use. CONSTITUTION:This invented sheath-core type polyester conjugated fiber has a core part composed of a mixed polyester in which the content of a polyalkylene ether contained in a blocked polyether amide composition is 0.05 to 5wt.% based on the whole fiber. The sheath part and the core part are arranged in a concentric configuration and the content ratio of the core part is 5 to 50wt.%. The cross section of the conjugated fiber is substantially a trifoliate shape and the modification degree (M) of the cross section satisfies 1.3 OMEGA.cm and the total fineness is

    Abstract: PURPOSE:To provide the subject fiber having a specific cross-sectional shape, having excellent opaque property, dyeability, strength and luster and further having a soft hand touch by copolymerizing with a specific amount of a metal sulfonate group-containing isophthalic acid component and with a specified amount of a polyalkylene glycol component, adding a delustering agent to the copolymer and subsequently spinning the copolymer. CONSTITUTION:A modified polyester copolymerized with an isophthalic acid component having a metal sulfonate group in an amount of 0.7-2.4mol% based on all dicarboxylic acid components and with a polyalkylene glycol component having a mol.wt. of 90-6000 in an amount of 0.2-10wt.% and containing 1.3-8.0wt.% of a delustering agent, is melt-spun through a spinneret having extrusion holes each having a modified cross-sectional shape to form uneven cross-sectional shaped fibers which are characterized by follows; a long axis A at the longest line portion of the cross section of each fiber and a short axis B vertical to the long axis A are satisfied with the equation I; the cross section of the fiber has eight leaf portions which are positioned at both the ends of the axis A and on both the lateral sides of the axis A in mutually faced states; depressions are disposed between the leaves; the lengths C of both the side leaves are satisfied with the equation II; the lengths D between the depressions are satisfied with the equation III; when the longest line among lines between cross points of the line A with the lines B-D is 1, the other lines are 0.6-1.0.
