Abstract
The invention relates to a silk flock slowly-cooling method for fine-denier spinning. According to the silk flock slowly-cooling method, a cooling device comprises a spinneret plate, an oiling device, a coiling device and a spinning heating sleeve which is connected with a silk outlet, wherein the silk outlet is formed in the lower end of the spinneret plate; and the sleeve diameter of the spinning heating sleeve is the same as the diameter of the aperture of the silk outlet of the spinneret plate, the spinning heating sleeve can be electrified to be heated, and the length of the spinning heating sleeve is 5 centimeters. The silk flock slowly-cooling method comprises the following steps of: (a) installing the spinning heating sleeve at the silk outlet of the spinneret plate, so that silk flocks pass through the spinning heating sleeve; and (b) electrifying and heating the spinning heating sleeve in the step (a) to ensure that the temperature change of silk flocks which are sprayed from the silk outlet is small, and cooling to normal temperature to achieve an effect of cooling the silk flocks slowly. By the silk flock slowly-cooling device which is used by the silk flock slowly-cooling method, the cooling speed of the silk flocks is reduced under the spinning heating sleeve, so that an effect of reducing broken ends can be achieved effectively; and the silk flock slowly-cooling device is simple in structure and convenient to use.
Description
Technical field
The present invention relates to but method of a kind of tow slow cooling for thin dawn spinning.
Background technology
Fine denier filament refers to filament number at the fiber of 1.0～0.5dpf, and filament number is called superfine Denier fibre at the fiber of 0.5～0.1dpf, and the fiber that filament number is lower than 0.1dpf is called fine-denier fiber.The one-component spinning process is generally adopted in fine count fiber production, one-component spinning process or conjugate spinning method are generally adopted in superfine Denier fibre production, and fine-denier fiber generally adopts the conjugate spinning method, and it is widely used in peach face, deer velvet, highly dense waterproof down-proof fabric, thick, the high-grade knitted fashionable dress of high perceptual Silk and underwear, high performance wiping cloth, medical protection, super clean quiet Work Clothes and is directly used in function sorbing material, filtering material, material which can retain moisture etc.Be that brocade is washed composite fibre or islands-in-sea type fibre equiconjugate fiber there is the complicated fine problem of opening in they in rear arrangement process, open the quality that fine quality directly affects finished product.And there is not out fine problem in the one pack system superfine Denier fibre owing to self be exactly superfine Denier fibre, and the therefore rear arrangement stage is fairly simple, can reduce rear arrangement cost than conjugate fibre.
But thin dawn spinning threadling in the actual production, because the spinneret orifice footpath is little, the diameter of monofilament is very little, and is very high to the requirement that spinning condition is stable, therefore in stretch orientation, wishes to carry out at a certain temperature.And conventional thin dawn spinning threadling, tow from spinnerets out after, namely cooled off by lateral blowing, tensile stress is large, causes easily the monofilament broken end, causes exorbitant expenditure.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and but method of a kind of tow slow cooling for thin dawn spinning is provided.
For solving above technical problem, the present invention takes following technical scheme:
A kind of tow slow cooling for thin dawn spinning is method but, the cooling device that the method adopts comprises the spinnerets that is connected with spinning manifold, be used for further oiling device and the batching apparatus of processing tow, wherein the lower end of spinnerets is provided with filament mouth, described cooling device also comprises the spinning heating muff that is connected with filament mouth, the barrel dliameter of this spinning heating muff is identical with the bore of the filament mouth of spinnerets, the simultaneously spinning heating muff heating of can switching on, and the length 5cm of spinning heating muff, but method is as follows in this tow slow cooling: (a), the spinning cartridge heater is installed in the filament mouth of spinnerets, allows tow through the spinning cartridge heater; (b), with the heating of switching on of the spinning cartridge heater in the step (a), guarantee from the poor variation of strand temperature of filament mouth ejection littlely, gradually to normal temperature, thereby realize tow slow cooling effect but.
Because the enforcement of above technical scheme, the present invention compared with prior art has following advantage:
The tow slow-cooling device that the present invention adopts, the cooling velocity of having slowed down tow under the spinning heating muff can effectively reach the effect that reduces broken end, and simple in structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of tow slow-cooling device of the present invention;
Wherein: 1, spinning manifold; 2, spinnerets; 20, filament mouth; 3, tow; 4, oiling device; 5, batching apparatus; 6, spinning heating muff.
The specific embodiment
As shown in Figure 1, the tow slow cooling that is used for thin dawn spinning of present embodiment is method but, the cooling device that the method adopts comprises the spinnerets 2 that is connected with spinning manifold 1, be used for further oiling device 4 and the batching apparatus 5 of processing tow 3, wherein the lower end of spinnerets 2 is provided with filament mouth 20, described cooling device also comprises the spinning heating muff 6 that is connected with filament mouth 20, the barrel dliameter of this spinning heating muff 6 is identical with the bore of the filament mouth 20 of spinnerets 2, simultaneously spinning heating muff 6 heating of can switching on, and the length 5cm of spinning heating muff 6, but method is as follows in these tow 3 slow cooling: (a), spinning cartridge heater 6 is installed in the filament mouth 20 of spinnerets 2, allows tow 3 through spinning cartridge heaters 6; (b), with the heating of switching on of the spinning cartridge heater 6 in the step (a), guarantee to change from tow 3 temperature differences of filament mouth 20 ejections little, gradually to normal temperature, thereby realize tow slow cooling effect but.
Slowed down the cooling velocity of tow in this enforcement under the spinning heating muff, can effectively reach the effect that reduces broken end, the broken end number of times is 3～5 times/class before using, and the broken end number of times is 0～1 time/class after using, and simple in structure, easy to operate.
More than the present invention has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; the equivalence that all Spirit Essences according to the present invention are done changes or modifies, and all should be encompassed in protection scope of the present invention.
