Abstract: PURPOSE:The yarn inlet of the cooling chimney is positioned at a specific distance from the spinneret down and cooling air at a specific temperature is forcibly blown from the cooling chimney to effect high-efficienty cooling and solidification of the yarn. CONSTITUTION:The extruded yarn is cooled with pre-cooling air (ar 10-20 deg.C) from the horizontal air blower 2, then introduced into the cooling chimney 3 where the yarn is cooled and solidified with the air lower than -5 deg.C. The cooling air is fed at a position downstream from the spinneret 1 by 0.05XW XV meter [W is the through-put of the polymer from each nozzle (g/min); V is the first take-up of the yarn (km/min) to effect forced cooling.

Abstract: PURPOSE:To enable a stable package configuration to be formed in a spindle drive type take-up machine by taking up the package in the non-contact way while setting the relationship between the traverse speed and the take-up speed within a predetermined range. CONSTITUTION:Polyamide fiber Y from a spun yarn mouth piece is intercepted and processed by air of a nizzle 4 and hot stretched by goddy rollers 5, 6 to be taken up by a take-up unit 10 into the form of barn with 4,500m/min or more speed while being traversed by a traversed fulcrum guide 8 and a traverse guide 9. A drive motor 11 of the take-up unit 10 is controlled to have a constant tension by a control board 14 consisting of a tension detector 7, a power controller 12 and a tension setter 13 to take up a package 15 in the non-contact way. Also, as the winding diameter is increased, the winding width is sequentially reduced and the spun yarn is taken up with slow traverse such that the traverse speed T is related to the take-up speed V, as follows V/4,000

Abstract: PURPOSE:To small amount of water-containing finishing oil is applied to a polyamide yarn after it is melt extruded and solidified by cooling, then drawn and heat set between mirror-finished rollers, further a water-containing finishing oil is applied additionally, thus giving desired amounts of water and oil in a direct spin-draw process. CONSTITUTION:A melt-spun polyamide yarn is solidified by cooling, treated with a very small amount of a water-containing finishing oil by means of an oiling roll 4, and drawn and heat set between a mirror-finished roll 5 and another hot mirror-finished roll 6. Then, additional water-containing finishing oil is applied and the resultant yarn is wound up. The peripheral speed of the roll is set over 3,000m/min, the oil pick-up is 0.2% in the first application and 0.5-1.5% in the second based on the yarn and the water is applied by 2-5% in the second oiling.
