Description of drawings
Describe the present invention by means of embodiment and accompanying drawing below;
Fig. 1 has schematically shown the device that is used to produce the device of filament yarn and is used for the production endless tow.
The specific embodiment
If filament yarn 3 will be spun, then follow the process of representing among the figure, reel 8 arrives the fracture reforming unit (for example seeing WO-A-00/77283) of a known construction.In described device, the polyester filament yarn on the reel 8 is extended, is fragmented into staple fibre and formed a kind of spinnable band.The elongation of filament yarn and fracture realize that by the paired roller that drives with friction speed its drive motors has high energy consumption.The speed of drive motors must accurately be adjusted and keep constant in addition.
In order to make the fracture reforming unit to the energy consumption of drive motors, accurately the requirement of the property adjusted and constant airspeed reduces, in the process shown in the figure, on filament yarn 3, produce tender spots, thereby in fracture conversion process subsequently, described filament yarn can change into required staple fibre, and energy consumption obviously reduces.As shown in the figure, the generation of tender spots is to be realized by the yarn reduction machine 9 that is arranged in the treating apparatus 6, it is arranged in the upstream for the extension 7 of yarn direction (arrow A) back, perhaps two extensions 7 and 7 ' between, perhaps for the extension 7 of yarn direction (arrow A) front ' and reel 8 between.
Endless tow 5 (figure right half of) arrive the treating apparatus 6 in device for spinning 4 downstreams ', it comprise represented among at least one extension-Tu two extensions 10,10 '-and curling stage 11.And then should curl stage 11, endless tow 5 is stored in a suitable container for example in cylinder 12, perhaps can be wound.This known process can be carried out or carry out discontinuously continuously, the difference of the continuous process of representing among discontinuous process and the figure is, the endless tow 5 of coming out from device for spinning 4 leaves in the cylinder, temporarily stores, and pulls out from cylinder then, extends, curls and deposit.
In order to obtain staple fibre, cylinder 12 is transported to a fracture reforming unit, wherein to cut off in the district at two, endless tow 5 fragments into staple fibre and is solidified into a kind of spinnable band in curing area.
For the fracture reforming unit is reduced the energy consumption of drive motors and the requirement of constant airspeed, in the process shown in the figure, on endless tow 5, produce tender spots, in the feasible fracture conversion process subsequently, described endless tow can change into required staple fibre, and energy consumption obviously reduces.As shown in the figure, the generation of tender spots realizes by yarn weakening apparatus 9, and it is arranged between the extension 10 of the direction of the supply (arrow A) back of device for spinning 4 and endless tow 5.
Under two kinds of situations of filament yarn 3 and endless tow 5, a series of devices can be considered as yarn weakening apparatus 9 to this particularly:
Producing tender spots in filament yarn 3 or endless tow 5 can also realize by the influence that heats up, and suitably is combined in the mechanical stretch on filament yarn 3 or the endless tow 5.In this case, yarn weakening apparatus 9 is chambers, and the portion space has the temperature of rising within it, and yarn or tow are conducted through this chamber.But yarn weakening apparatus 9 can also be the form of ring, and it centers on yarn or tow, and is heated to for example 160 ℃ to 280 ℃.
Producing tender spots in filament yarn 3 or endless tow 5 can also realize by plasma.With Cement Composite Treated by Plasma is the very large system of effect, to change the surface of polymer by chemical mode.Consequently, by the fiber of plasma resonance than untreated fibers " more crisp ".Handle by so-called plasma flame, can produce very high temperature and can be used under the normal pressure.In this case, yarn or tow are conducted through the chamber that produces plasma.Under the situation of plasma torch (jet flames system), oxygen and fuel mix and in the flame internal-combustion, in most of the cases fuel is acetylene or propane.The raw material of a kind of wire or powdery is transported in the flame simultaneously, and quickens in the direction of filament yarn 3 or endless tow 5 by compressed air.The particle of fusing is distributed on filament yarn 3 or the endless tow 5 with very short random pulses, thereby produces the tender spots of random distribution in yarn.
Yarn weakening apparatus 9 can also be made of the electron beam treatment device, and it makes yarn or tow be subjected to the effect of high-velocity electrons.Be called as in the processor of EB processor at these, high voltage is applied on the tungsten filament of the internal tightness of vacuum chamber, and consequently, described tungsten filament produces electron cloud.High speed is isolated and accelerated to electronics from electron cloud.The electronics that is accelerated leaves vacuum chamber and passes a paper tinsel window, enters into its direction that is directed filament yarn vertical with electron beam 3 or endless tow 5, causes that molecule required in described filament yarn 3 or the endless tow 5 changes, and is tender spots in this example.When adopting traditional impact system, electronics enters into fiber and destroys the hydrogen bond of large-scale molecule.This destruction of taking place at random produces preferred compensation point, and the resistance of yarn reduces 60%, makes the output of fracture reforming unit motor correspondingly reduce 60%.
The major advantage that described spinning apparatus has is, as final products, a kind of filament yarn 3 or endless tow 5 that has tender spots is provided, break with the process that obtains staple fibre ensuing, no longer need to be loaded into as yarn that does not have tender spots or tow many degree, make and obviously reduce to the requirement of the energy consumption of fracture reforming unit and size design with to the constant requirement of the speed of its drive motors.So the cost of the reforming unit that ruptures also descends.
