Abstract: PURPOSE:To provide a melt-spinning spinneret capable of spinning a plural kinds of yarns of wide yarn variety with a single spinneret at the same time by opening nozzle holes on a circular spinneret in the form of blocks having specific arrangement and spacings between holes for each yarn. CONSTITUTION:Nozzle holes 2 are opened on a circular spinneret 1 having a diameter (a) of 70-140mm in the form of blocks for respective yarns. The gap (b) between the blocks is 8-35mm and the number of blocks is 2-4. The nozzle holes of each block are arranged in alternate zigzag form on the cross points of plural parallel linear line groups having a spacing (c) of 5-10mm and >=4 parallel linear line groups having a spacing (d) of 3-10mm. The number of nozzle holes on each block is 12-100. The chimney cooling air is blown in the direction of the arrow 3 to minimize the generation of turbulent air flow and enable stable melt-spinning of a yarn having a filament fineness of 0.5-20d.

Abstract: PURPOSE:To provide a melt-spinning spinneret capable of spinning a wide variety of yarns by opening nozzle holes on a circular spinneret in specific arrangement, spacings and distribution density. CONSTITUTION:Nozzle holes 3 are opened on a circular spinneret 2 in alternate zigzag form on the cross points of a parallel linear line group having a spacing (a) of 5-15mm and a linear line group perpendicularly crossing the former group and having a spacing (b) of 3-10mm. The average distribution density of the nozzle holes on the spinneret is 2-6 holes per 1cm . The chimney cooling air is blown in the direction of the arrow 1 to minimize the generation of turbulent air flow and enable stable melt-spinning of a yarn having a filament fineness of 0.5-20d.

Abstract: PROBLEM TO BE SOLVED: To provide a yarn interlacing apparatus capable of distributing gas- liquid mixture for normal cleaning to the whole interlacing nozzles in the yarn interlacing apparatus having interlacing nozzles of a number of spindles. SOLUTION: Each spindle of a textile machine comprising a number of spindles is provided with an interlacing nozzle 1, a first main supply line 10 for feeding a pressurized gas for interlacing and a second main supplying line 20 for feeding a gas-liquid mixture for nozzle cleaning are independently installed. Branched flow channels 3 and 4 are branched from plural parts dispersed in the longer directions of both the main supply lines 10 and 20, connected to three-way change valves 5, and flow channels 6, 6a and 6b extended from the three-way change valves 5 are connected to the interlacing nozzles 1. The branched flow channels 4 are extended upward above the main supply line 20 at the branched parts from the main supply line 20.
