Description
The present invention relates to a kind of manufacture method of viscose rayon and the spinning equipment that viscose rayon Silk Mill uses, i.e. viscose rayon high-speed spinning spinning machine.
In the viscose rayon production process, the viscose ripening degree is the major parameter of spinning technique before spinning, and it influences the spinnability of viscose glue, influences the quality and the dyeing uniformity of artificial silk, and the potential shrinkage of artificial silk.
Think in the prior art and spin preceding viscose ripening degree when 9～9.3 scope, the corresponding difference minimum of viscose filament yarn dye uptake.So long-term regulation viscose ripening degree value is 9～9.3, guarantees the dyeing uniformity of artificial silk with this, but the property spun And nonoptimal value of the viscose glue of viscose ripening degree value in 9～9.3 scopes.Because this regulation, the raising that makes spinning machine spin speed is restricted over a long time, 92 meters/be divided into the highest spinning speed; Also just because of this regulation, cause the artificial silk dyeing uniformity not have new improvement and raising for a long time and ignored spinning machine board viscose ripening Du ， And, the top-quality product rate of artificial silk can not break through this upper limit more than 90%.
Existing viscose rayon wet method repiece spinning machine, because the technical performance of equipment and the high speed spinning that structure can not be applicable to the low value degree of ripeness, the existing problem division of its structure is as follows.
The board sebific duct of existing spinning machine is not circulating, and viscose glue stop distribution time difference in pipe is big, though Japan has added a circulating pump in the middle of the sebific duct of board loop, but still part viscose glue overstand in sebific duct is arranged, thereby board viscose ripening degree can not be well controlled; The lifting take-up mechanism of existing R531 spinning machine is that the cylinder slot type cam ， And that is equipped with on difference little case, speed change gear and worm and gear device and worm gear rotates and axially move back and forth the rotating speed that makes cylinder slot type cam forms rotating speed for the sometimes fast and sometimes slow rotation of even speed change poor micromotion by the constant speed of worm screw.Cylinder slot type cam drives two rollers on 180 ° of symmetric positions, each roller is on the chuck that is fixed on lifter drawing bar of single armed, so that lifter drawing bar pumps, obviously mechanism's complexity, again since a cam undertake about the work in two districts, the mutational load point of workspace cam that causes board is on 2 of symmetry, load point is concentrated, vibrations are big, and reciprocal time can not surpass 39 times/minute, can't adapt to high speed spinning; The repiece instrument of R531 and R535 spinning machine all is the repiece bowl; Transmission device external and domestic spinning machine all is the transmission of gear type collective.
According to the above, spinning machine has following shortcoming at present:
1, the viscose ripening degree difference＞3(NH that comes out by the board sebific duct
4The Cl salt figure).Thereby, cause the quality of spinning to be affected, present top-quality product rate can only reach 90%.
2, again because a large amount of viscose ripening degree value that contains that shower nozzle comes out is 9 viscose glue, spinnability is poor, can not realize high speed spinning.
3, for viscose ripening degree value be 9 viscose filament yarn, not only spinnability is poor, and lousiness is many, and the brute force of silk is poor, so that can not strengthen stretching, and this just brings the post processing problem of viscose rayon, and retraction is serious.
4, China and viscose rayon Silk Mill in the world all are integrated mills at present, its reason is that the sulfonation board of the glue department of viscose rayon Silk Mill went out one time viscose glue in per four hours, in order to eliminate the influence of four hours periods, sulfonation board number is added, become factory and build to such an extent that be the bigger the better.The fact is that the board sebific duct is particularly important to the control of viscose glue, plant layout also can't be improved greatly the present situation that the part viscose glue reached 5 days promptly 120 hours at intraductal retention time again, with 100,000,000 yuan of great investments with on cycle of eliminating four hours be continous mode production, cause the national conditions that the capital construction time is long, the slow and fund of producing effects overstocks, is not suitable for China.This also is the one of the main reasons that causes the artificial silk of the long-term a large amount of import Japan of China and its country of other country.Desire to exceed tens of times price ， And and to be to buy artificial silk to export at a low price cotton linter with ten thousand tons surprising numeral surplus annual ten every year.
5, the lifting take-up mechanism of cylinder slot type cam, because the lifting in two districts of cam burden, and each district must control lifting simultaneously by two cams, thereby the mutational load point that makes whole unit cam is on 2 of symmetry.It is big to form vibrations, and the lifting reciprocal time is limited to 39 times/minute.
6, the tophan box function of the board differential mechanism of existing lifting take-up mechanism and 1: 9 tapering repeats, the influence silk and alleviate performance, the coiling doubling that is easy to be shaped, and the complicated cost height of this mechanism.
7, the repiece bowl can't be finished the repiece task of high-speed spinning.
8, because spinning machine is collective's transmission, must shutdown change gear to adjust the artificial silk fiber number, when shutting down the accent fibre, whole shower nozzles of spinning machine (48 or 77 shower nozzles) must all be changed.
9, owing to transfer fine difficulty, therefore, the silk and the ectonexine thickness difference of R531 and R535 spinning machine are 5.2%, and the ectonexine thickness difference of Japanese Kuraray is 1.4%, and difference is all bigger than normal, and this is can't regulate the pump amount separately in silk and the forming process and cause.
10, silk and inside and outside aberration R531 and R535 are 1.8%, and Kuraray is 1.3～3.5%, and this is to cause owing to not regulating spinning disc and following spinning disc speed separately.
11, spinning machine adopts collective's transmission unfavorable to the board vibration, and because of there has been the capillary ripple phenomenon in the viscose glue thread of being extruded by shower nozzle in the drawing process, fuselage shaking directly makes capillary ripple enlarge, and causes evenness fault, powerful decline, capillary and the broken end of silk.
The objective of the invention is to propose a kind of production method of new artificial silk and new spinning equipment, improving quality, the spinning speed of spinning, dyeing uniformity and strengthen the brute force of silk, And and change the aftertreatment performance and the viscose rayon Silk Mill of silk
The qualifications of factory rules and regulations mould.
The viscose ripening degree is the major parameter of spinning technique before spinning, and the change of viscose ripening degree has a significant impact for spinning condition before spinning, and the viscose ripening degree was 9 before long-term both at home and abroad regulation was spun.The present invention increases according to the sulphonic acid ester molecule of the low more then low esterification degree of viscose ripening degree value, the intermolecular hydrogen bonding active force is big more, the trend that aligns of the viscose glue thread linear molecule of the spray orifice that increases at flow velocity is big more, axial brute force based on thread is high more, this principle that spinnability is strengthened, and can improve simultaneously again under the prerequisite of dyeing uniformity of artificial silk, adopt the low value viscose ripening degree spinning below 7.5, improved spinnability, provide and realized that 120～140 meters of per minutes spin the good process conditions of speed.
