Abstract
The invention relates to a water cooling method in polyester fiber melt spinning, additionally installing spray generator at the air intake of the original side blower or around the spinning window, and able to generate water spray, water foam, and water bubble or water film according to the needs; the melt streamlet extruded from spinning components passes through swelling area into deformation area, then blows the water spray, water foam, and water bubble or water film in the spinning window by a breeze at a speed of 0.05-0.1 m/s to make them fill up the whole window to cool threads, and after heat exchange, the produced water drops and surplus water are collected by water collector. Its advantage: accelerating cooling, reducing skin-core structure of threads and avoiding swing of threads caused by wind cooling. It makes fiber size uniform, breaking tenacity high and product quality good.
Description
Technical field
The invention belongs to a kind of cooling means in the chemical fibre industry production polyester fiber process.
Background technology
In melt spinning was produced at present, polyester slice produced the spinning polymer melt of High Temperature High Pressure through the screw extruder heating.Melt is extruded from the spinneret orifice of filament spinning component spinnerets, produce and partly melt the filament of bodyization, this silk needs through the lateral blowing cooling forming, and present lateral blowing cooling is to adopt folk prescription to blowing or adopts hoop to dry, to that extrude, high temperature, partly melt body chemical fibre silk and carry out cooling forming.Its shortcoming is: because the ratio of specific heat value of air is lower, it is slow to produce cooling rate then, and silk is easy to generate skin-core structure, causes the swing of strand again because of blowing of wind, makes fiber number CV value become big, and fracture strength is not high.The poor quality is a bottleneck of producing high-quality chemical fibre silk.
Summary of the invention
The invention provides the water-cooling method in a kind of polyester fiber melt spinning, to solve at present because the problem that fiber number is inhomogeneous, fracture strength is not high, cooling effect is bad during the lateral blowing cooling forming.The technical scheme that the present invention takes is:
Air inlet place at former lateral blowing installs water fog generator additional, and this water fog generator can produce water smoke, foam, bubble or moisture film as required; The melt thread of extruding from filament spinning component is after fluffing zone enters the deformation district, water smoke, foam, bubble or the moisture film that will be produced as required by water fog generator is blown into this water smoke, foam, bubble or moisture film in the spinning window with the gentle breeze of wind speed 0.05～0.1 meter per second, make this water smoke, foam, bubble or moisture film from top to bottom be full of the spinning window, silk is cooled off, and water droplet that produces after the heat exchange and unnecessary water are received water through water collector.
The present invention is that polyester fiber changes water-cooled method into by the lateral blowing cooling in molten spinning, advantage is that the melt thread extruded from filament spinning component is after fluffing zone enters the deformation district, replace original air-cooled with water smoke, foam, bubble or moisture film, accelerated cooling velocity, reduced the skin-core structure of silk, avoided swing simultaneously because of the air-cooled silk that causes.Make the fiber number of fiber even, fracture strength height, good product quality.330 dtexs/96 rhizoids are example to produce polypropylene fibre, and when former employing lateral blowing cooled off, fracture strength was 7.2cN/dtex to the maximum, change into adopting after the water-cooled, and the intensity raising reaches 10.8cN/dtex.The fiber number CV value of fiber drops to 3.8 by original 4.6, has improved the quality of product widely.
