Technical field
The utility model relates to the fiber process device of chemical fibre industry, relates in particular to a kind of relaxation heat setting device.
Background technology
Polyster fibre after spinning and stretching, its supramolecular structure is not perfect, and stable not, although the deformation major part that occurs when stretching is non-response plastic deformation, and often be fixed because of crystallization, but still some is at room temperature replied because of the lax of tensile stress, whole physics-engineering properties shows as the intensity height, ductility is low, initial modulus is larger, but toughness and elasticity are relatively poor, particularly be heated, be subjected to wet or can produce very large contraction when being subjected to humid heat treatment, do not meet the requirement of rear road processing, for this reason, in rear process by the polyster fibre tow is carried out HEAT SETTING, repair and improve the structure that fiber has formed in forming process, improving the DIMENSIONAL STABILITY of fiber, and further improve the physical-mechanical property of fiber.
Heat setting process mainly is divided into tension force HEAT SETTING and relaxation heat setting.Relaxation heat setting is the HEAT SETTING that fiber carries out under free state, and fiber is not subjected to the tension force effect during owing to typing, and its macromolecular chain activity is large, can be relaxed fully, and the fiber internal stress after the typing can discharge fully, the structure of fiber and stable performance.Especially for three-dimensional polyester staple fiber, effectively relaxation heat setting can improve the shape stability (boiling water shrinkage) of fiber, further improve the physical and mechanical properties (knot strength, ABRASION RESISTANCE, fixedly crimpness) of fiber, improve the dyeability of fiber, satisfy the following process requirement of fiber.
Existing setting machine is the short closed two cavity heaters of length mostly, and the time that tow stops in cavity, short typing was abundant not, and the temperature in the cavity differs larger, and setting temperature is unstable, so fixed effect is relatively poor.Tow needs after HEAT SETTING through the cooling and shaping operation in addition, and sometimes cooling is not thorough, and the finished silk performance difference is larger, and quality is unstable.
The utility model content
The purpose of this utility model is to solve above-mentioned problems of the prior art, by increasing the heating cavity (increasing to 4 thermals treatment zone from 2 thermals treatment zone) of baking oven, prolong the heated time of tow in baking oven, and guarantee that the fiber setting temperature is even, internal stress discharges fully; Above cooling device, add a machine of taking off, tow has been carried out simple shredding, accelerated cooling rate, intrastitial hot gas, aqueous vapor are fully volatilized, helped tow cooling; Increased transfer chamber and strengthened fixed effect, reduced to pack on the impact of fiber scroll after the HEAT SETTING at once.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of relaxation heat setting device, it mainly comprises heating and dehumidification district, dryness finalization district, cooling and shaping district, wherein said heat setting device comprises first thermal treatment zone, second thermal treatment zone, the 3rd thermal treatment zone, the 4th thermal treatment zone, described cooling and shaping district comprises cooling forming device, cools off little carrier bar, and a machine of taking off of being located at chainlet plate top.
The beneficial effects of the utility model are: the utility model adopts four thermals treatment zone to prolong the heated time of tow in baking oven, and guarantee that the fiber setting temperature is even, internal stress discharges fully, and the intramolecule orientation has the sufficient time to change, thereby realizes increasing the effect of tow HEAT SETTING; Cooling device has comprised a machine of taking off that cools off little carrier bar and be located at cooling chainlet plate top simultaneously, above cooling device, add a machine of taking off, tow has been carried out simple shredding, accelerated cooling rate, intrastitial hot gas, aqueous vapor are fully volatilized, help tow cooling.
As preferably, described cooling and shaping is provided with transfer chamber behind the district, and the transfer chamber structure is used for strengthening fixed effect, reduce HEAT SETTING after at once packing on the impact of fiber scroll.
Further, described dryness finalization district comprises air inlet, heater, the web that is located at the body below and the air outlet of being located at the body top, described air inlet, heater, web, air outlet consist of airflow channel from bottom to top, the blowing mode of this mode is so that fiber is in fluffy and half floating state, so that cooling air penetrates easily, moisture is taken away, thereby strengthened the fixed effect of fiber, improved bulking intensity and the smooth degree of fiber.
Compared with prior art, advantage of the present utility model is as follows: 1, adopt four thermals treatment zone to prolong the heated time of tow in baking oven, and guarantee that the fiber setting temperature is even, internal stress discharges fully, the intramolecule orientation has the sufficient time to change, thereby realizes increasing the effect of tow HEAT SETTING; 2; Take off a machine structure tow that is heated is carried out simple shredding, accelerate cooling rate, intrastitial hot gas, aqueous vapor are fully volatilized, help tow cooling; 3, the dryness finalization district is blown into hot blast from bottom to top, so that fiber is in fluffy and half floating state, so that cooling air penetrates easily, moisture is taken away, thereby has been strengthened the fixed effect of fiber, has improved bulking intensity and the smooth degree of fiber; 4, at once packing had been strengthened fixed effect to the impact of fiber scroll after the transfer chamber design can effectively reduce HEAT SETTING.
