Abstract
The invention discloses a method for preparing a super-heavy denier lustrous polyester drawing filament with the total fiber density up to 1,000 denier. The method comprises the following steps: a lustrous direct-spinning fused mass made from PTA and MEG through polymerization is conveyed to a spinning box body under the action of a booster pump, and a metering pump is used to carry out accurate measurement of 12 bundles of fused mass-shaped fibers with the fiber density of between 149.7 and 150.4 denier; after side blowing cooling and even oiling by an oil wheel, the first two-in-one combination of the tows is carried out through a pressure air preheating interlacer and a thread guide so as to form 6 fiber threads; then after draw forming is finished by a first spinning reel hot roller and a second spinning reel hot roller, the second three-in-one combination of the 6 fiber threads is carried out so as to form 2 fiber threads after the second combination; and finally, when package build is finished by a winding head, two required super-heavy denier lustrous polyester drawing filaments are obtained. The product prepared through adopting the method has the advantages of high added value and unique style of downstream textile fabric, and can be widely used in novel face fabric fields such as home textile, decoration and automobile interior decoration.
Description
Technical field
The present invention relates to the preparation method of light polyester drawn yarns, refer more particularly to a kind of preparation method of ultra-coarse denier lustrous terylene drawn yarn.
Background technology
Ultra-coarse denier lustrous terylene drawn yarn adopts by what p-phthalic acid's (being called for short PTA), ethylene glycol (abbreviated as MEG) polymerization were made to be had light directly to spin melt to be raw material, to make by operations such as spinning, stretchings.The line density of polyester drawn yarns is the thickest in the chemical fibre industry at present only can reach for 300 dawn, its production technology is: with PTA, the MEG polymerization is made, and to have light directly to spin melt be raw material, after the booster pump supercharging, send into spinning manifold by the melt Conveying pipeline, and through the measuring pump accurate measurement, after filtering, filament spinning component in spinning manifold forms melt shape fiber, become as-spun fibre through the lateral blowing cooling curing again, again after oil tanker oils, again through the first draw-off godet hot-rolling, the second spinning reel hot-rolling HEAT SETTING that stretches, by thread guide the polyster fibre line being merged into then has a light polyester drawn yarns about 300 dawn, will have the package of light polyester drawn yarns to be shaped by winding head at last.Above-mentioned preparation method's shortcoming is: the later stage of three leaf odd-shaped cross section lustrous fibre lines merges in the production technology, makes to lack cohesive force between monofilament, easily diverges in the use of back road; Cohesive force inequality between monofilament, during stretching between monofilament tension force differ, three leaf abnormity have that light produces easily that boundling is irregular, single wire fracture forms lousiness, thus road, influence back is weaved and the flatness of cloth cover, can't reach the back processing request of coarse denier fiber; And the polyester drawn yarns that conventional spinning obtains is the thickest only to reach for 300 dawn, and range of application is restricted.
Summary of the invention
Technical problem to be solved by this invention is: a kind of preparation method that can reach for 1000 dawn and can produce the ultra-coarse denier lustrous terylene drawn yarn of lousiness hardly will be provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the preparation method of described a kind of ultra-coarse denier lustrous terylene drawn yarn, with by the p-phthalic acid, the ethylene glycol polymerization is made, and to have light directly to spin melt be raw material, be characterized in: comprise the steps: that (one) will have light directly to spin melt is 280 ℃～285 ℃ melt Conveying pipelines in the scope by temperature, simultaneously under the effect of booster pump, be transported to spinning manifold and through the measuring pump accurate measurement, measuring pump is controlled at 4.9～5.1kg/min with the melt flow precision, form 12 bundle melt shape fibers behind the filament spinning component of melt in spinning manifold, and the line density of every bundle fiber was controlled at for 149.7～150.4 dawn; (2) then through the lateral blowing cooling, curing molding, the temperature of lateral blowing is 20 ℃～25 ℃, and humidity is 65% ± 5%, and wind speed is 0.5～0.7m/s; (3) again after oil tanker evenly oils, make the preliminary obvolvent boundling of tow through pressing empty pre-Network device, by thread guide tow is carried out the two-in-one merging first time then, form 6 bundle fiber lines; (4) 6 bundle fiber lines are more respectively through the first draw-off godet hot-rolling, the second spinning reel hot-rolling HEAT SETTING that stretches, and then 6 filamental threads are carried out the three-in-one merging second time respectively through Network device and thread guide, form 2 filamental threads after secondary merges, the filamental thread after the merging is through the obvolvent of the nozzle of interlace boundling; (5) then these 2 filamental threads after secondary merges are shaped through the winding head package, finally obtain 2 required ultra-coarse denier lustrous terylene drawn yarns.
Compressed-air actuated pressure is 1.3～1.8kg in the empty pre-Network device of above-mentioned pressure.The rotating speed of above-mentioned oil tanker is 15～20 rev/mins, and oil concentration is 12%～14%.The pressure that above-mentioned booster pump provides is 8-10kg/cm
2The pressure sky that the nozzle of interlace of described tow process uses is 3.5-4.0kg.
The present invention further technical scheme is: before lateral blowing cooling, make filamental thread pass through impurity in 40 to the 50 purpose metal sand assembly melt filtration earlier.
The present invention further technical scheme is: tow around 9.5 circles, encloses around 7.5 on the second spinning reel hot-rolling on the first draw-off godet hot-rolling when two godets-stretchings are finalized the design.
The invention has the beneficial effects as follows: use above-mentioned preparation method, can obtain the ultra-coarse denier lustrous terylene drawn yarn that total fiber number reached for 1000 dawn, the value-added content of product height, back road Fabric Style uniqueness can be widely used in house and spin, decoratees, reaches novel fabric fields such as automotive trim.
