Description
Technical field
The utility model relates to a kind of production equipment of polyamide fibre, particularly a kind of production equipment of 5～40D polyamide fibre 6FDY long filament.
Background technology
5～40D chinlon 6 filament is of many uses, not only, for through compiling weft-knitted lace and woven, is also applicable to knit socks.FDY(FULLY DRAWN YARN, fullly drawn yarn (FDY)) technique is the conventional production technology of 5～40D chinlon 6 filament.As depicted in figs. 1 and 2, traditional FDY equipment comprises screw extruder 1 ', melt pipe arrangement 2 ', a plurality of spinning manifold 3 ', monomer suction system 4 ', quenching air window 5 ' (middle section of quenching air window is provided with the frame 6 ' that oils of oil feeding system), path 7 ', pre-Network device 8 ', a pair of cold roller seal wire, a pair of hot-rolling, master network device, jockey pulley and the winding head (all not shown) sequentially arranging, and traditional FDY technique is roughly divided into following 5 steps:
1, melting, take chinlon 6 section as raw material, through screw extruder 1 ' melting, extrudes, by melt pipe arrangement 2 ', is dispensed to a plurality of spinning manifolds 3 ';
2, spray silk, in spinning manifold 3 ', be provided with melt metering pump, spinning pack and heat-insulation system, in a common spinning manifold, be provided with 2 melt metering pumps and 8-12 spinning pack, heat-insulation system is for keeping the high temperature of melt, melt metering pump is delivered to spinning pack by appropriate melt and is sprayed silk, then takes the volatile matters such as most monomer away by monomer suction system 4 ';
3, cooling and oil, then chinlon filament approaching side blowing window 5 ' carries out coolingly, and the middle section of quenching air window is provided with the frame 6 ' that oils of oil feeding system, and for oiling to chinlon filament boundling, now chinlon filament has been cooled to solid-state;
4, pre-network, the chinlon filament after oiling forms tow by entering pre-Network device 8 ' by path 7 ', with equal dispersant, increases the obvolvent degree of tow;
5, reel, then through a pair of cold roller seal wire, enter master network device through a pair of hot-rolling again, finally by jockey pulley, enter winding head and be coiled into spinning cake.
But this traditional production equipment and process makes, 5～40D chinlon 6 filament intensity of producing is not high, silk is not straight, while being used for knitting socks, can cause fabric out-of-flatness, the defects such as lines is unintelligible, and socks are had relatively high expectations to the definition of flatness and lines, have therefore produced contradiction.After studying for a long period of time, applicant finds: conventionally for civilian conventional silk, from spinning pack chinlon filament out greatly about 260 ℃ of left and right, approaching side blowing window immediately after monomer suction cover, owing to oiling, be erected at again the stage casing of quenching air window, therefore oiling is to carry out middle period cooling, so generally speaking, shorter during this period of time from spinning pack chinlon filament out to the frame that oils, just determined that the cool time before oiling is shorter, cooling velocity is too fast.In this shorter cool time, too fast cooling velocity has caused the problem that yarn strength is not high, silk is not straight just.In addition, the temperature of the wind that quenching air window blows out is 16～20 ℃, and the temperature difference of cooling front and back is too large, makes excessive velocities, also can cause long filament internal approach degree and the uniformity to decline.Therefore need be improved.
