Description
Technical field
The present invention relates to a kind of production technology of coloured and functional industrial polyester fiber, be applied to the polyester industrial yarn modification, in particular, be meant and adopt master batch melt injection method to produce polyester industrial yarns such as colored terylene industry silk and other functional form such as fire-retardant, antistatic, antibiotic, uvioresistant, belong to textile technology field.
Background technology
Terylene (PET) industry silk is compared with the normal domestic fiber, is characterized in having the intensity height, and percent thermal shrinkage is low, the physical property of the high excellence of modulus, thus have industrial use widely.Carry out modification by polyester industrial yarn to routine, polyester industrial yarns such as colored terylene industry silk and other functional form such as fire-retardant, antistatic, antibiotic, uvioresistant have also been developed, existing coloured or functional industrial polyester fiber production technology, general adopt master batch and conventional high sticking section to be pre-mixed after, together by drum dried, drop into screw rod jointly and carry out spinning again.This technology has following shortcoming: (1), high sticking section need be carried out redrying, waste energy, and are difficult to guarantee with the master batch mixing uniformity; (2), master batch and conventional high sticking section use same screw rod to carry out fusion, the master batch heated time is long, degraded is serious, the physical property of influence industry silk, adopt the polyester industrial yarn of this explained hereafter, its best fracture strength can only reach 7.5CN/dtex, and the fracture strength of conventional polyester industry silk generally can reach 8.1CN/dtex; (3), during change of product,, can produce a large amount of useless transitional products, unit cost increases greatly because transition blend melt amount is bigger.
Summary of the invention
For solving the above-mentioned defective of prior art, the object of the present invention is to provide a kind of production technology of coloured and functional industrial polyester fiber, reduce the adverse effect of modification to the physical property of polyester industrial yarn own, in modification, keep the intrinsic superior physical properties of polyester industrial yarn to greatest extent, improve the flexibility of producing simultaneously, adapt to little, the various in style characteristics of differential modified product order.
The technical scheme that the present invention is taked for achieving the above object is: a kind of coloured and functional industrial polyester fiber production technology comprises the steps:
1, the master batch that the master batch hopper is produced is put into fusion formation master batch melt in the small screw after drying;
Described master batch is according to producing optional from color grain such as black, yellow, blueness, redness, green master batch etc. any one of needs, or any one of functional form master batch such as fire-retardant, antistatic, antibiotic, uvioresistant master batch etc.;
The drying of master batch adopts twin master batch drying system, promptly divide into the spiral agitating type drier of a 20L at the master batch hopper, bottom polyphone one cover 100L vertical filling formula drying tower, the spiral agitating type drying system helps producing flexibly various be pilots, the fill-type drying tower is used for more large batch of production, so just can change the line of production flexibly, and the waste material that produces in the process of changing the line of production is few;
In the above-mentioned master batch drying process, baking temperature is 130～170 ℃, is preferably 155 ℃, and be 6～12 hours drying time, is preferably 10 hours;
Because the restriction of manufacturing technique, the intrinsic viscosity of master batch can only reach about 0.6 at present, and the viscosity of conventional high sticking section is generally more than 1.02, the temperature of master batch fusion is high more, the time of staying is long more, the degraded of master batch melt is serious more, in order to reduce the degraded of master batch melt as far as possible, keep better physical property, reduce master batch melt temperature of being heated and the time of being heated to greatest extent, the present invention adopts the small screw of a platform independent with the master batch fusion, 275～290 ℃ of temperature, preferred 280 ℃, 4～6 minutes melting times, preferred 5 minutes, 280～285 ℃ of master batch melt temperatures;
2, above-mentioned master batch melt is injected directly into spinning pump in the manifold by Melt Pump before, make in the static mixer of conventional high sticking section melt before spinning pump for preparing in master batch melt and the driving screw and evenly mix;
Conventional high sticking section fusion in driving screw of output from solid state polymerization reactor, 302 ℃ of melt temperatures, the conventional high sticking section melt after the fusion is injected in the static mixer gage outfit pressure 150bar; Simultaneously, the master batch melt of fusion from small screw also is injected in the static mixer and conventional high sticking section melt mixed through Melt Pump, and Melt Pump is injected ratio 3% ratio of total amount (injection rate with), injection pressure 130bar; 300 ℃ of temperature in the described static mixer, the time of staying of blend melt in static mixer is 0.1 minute.
3, mixed melt Conveying in the step 2 is carried out spinning to filament spinning component.
The blend melt that mixes in the static mixer is entered into filament spinning component through spinning pump, adopt conventional high strength yarn drawing-off winding process to carry out spinning and get polyester industrial yarn.
The invention has the beneficial effects as follows: 1, the present invention adopts master batch melt injection method, the master batch melt temperature is descended, the time of staying at high temperature reduces, it only is 1/3rd of original technology, in the common process, before entering filament spinning component, the master batch melt is about 15 minutes 300 ℃ of time of staying, severely degrade easily takes place in the master batch melt under this high temperature and time, the present invention adopts independent small screw that master batch is carried out fusion, mixes with conventional section melt by the Melt Pump injection then, like this before entering filament spinning component, the master batch melt is 4～6 minutes 280 ℃ the following time of staying of temperature, and the time of staying under 300 ℃ temperature is 0.1 minute, only is 1/3rd of original time of staying, thereby reduced the degraded of master batch melt to greatest extent, make it to keep good physical property in spinning process, spin the polyester industrial yarn that comes like this, fracture strength reaches 8.0CN/dtex, extension at break 13%, dry-hot shrinkage be 6.5% (177 ℃, 1min, 0.05CN/dtex); 2, conventional high sticking section directly is delivered to spinning screw from solid state polymerization reactor, prevents that high sticking section from absorbing moisture in air, thereby has avoided the redrying of high sticking section, has saved energy consumption; 3, the master batch drying process adopts twin master batch drying system, has greatly improved the flexibility of product conversion, compares with common process, produces the transition material of product conversion hardly.
