Abstract
The invention discloses a method for improving evenness of terylene spunbonded nonwoven fabrics and an electrostatic filament dividing device. The method is to apply a certain amount of positive electrostatic charge on melt-spinning cooled fibers through an electrostatic discharging rod at the entrance of a drafting device of production equipment for the terylene spunbonded nonwoven fabrics, wherein the amount of the applied positive electrostatic charge should ensure that the fibers repel each other for being charged with the same kind of charges after leaving the drafting device. An electrostatic eliminator is installed at the tail end of net curtain of a lapping machine. By adopting the technical scheme of the invention, the problem of evenness of the terylene spunbonded nonwoven fabrics, a problem that people have long been hoping earnestly to solve, is solved, and especially to terylene spunbonded nonwoven fabrics of less than 100 grams per square, the advantage is more obvious.
Description
Technical field
The present invention relates to a kind of terylene spun-bonded non-weaving cloth production technology.
Background technology
Terylene spun-bonded non-weaving cloth is also claimed terylene non-woven fabric.Spunbond technology is a kind of non-weaving cloth production technology that development in recent years is very fast, technology content is higher, is one of main method of processing at present non-weaving cloth.Spun-bond process is that melt spinning becomes the net method; Utilize the spinning principle of chemical fibre, in polymer spun silk formation process, the melt thread of extruding is cooled off, form filament through quench air; Be laid in into then and become net on the lace curtaining, form the spun-bond process non-weaving cloth after consolidation device is handled the back.
As everyone knows; With regard to present big plate slit air drawing because spinning speed is fast, between fiber and the air-flow, between fiber and the fiber, between fiber and the equipment to contact separation process each other short; Fiber is easy to generate doubling, tow, teeth etc., causes Fiber Distribution inhomogeneous.Require the high product of the uniformity for some; Such as the dull and stereotyped nonwoven fabric that is used for the reverse osmosis membrane base cloth, because uniformity requirement is very high, present production technology other indexs except that the uniformity are all satisfied; And the uniformity is still unresolved; Be developing new market, capture frontier, just must make great efforts to improve the product uniformity as enterprise.
Summary of the invention
For thoroughly solving product uniformity problem, the present invention provides a kind of method that improves the terylene spun-bonded non-weaving cloth uniformity, and a kind of static of this method of proposition enforcement divides silk device.Through this device melt spinning is added a certain amount of positive electrostatic charge through cooled fiber, fiber separates it rapidly because of having like charges after leaving drawing-off gas, reach the purpose that reduces doubling, tow and teeth, improves the product uniformity.
Technical scheme of the present invention is; A kind of method that improves the terylene spun-bonded non-weaving cloth uniformity; It is the extension apparatus porch at the production equipment of terylene spun-bonded non-weaving cloth, is that the cooled fiber of melt spinning applies a certain amount of positive electrostatic charge through an electrostatic discharging rod, the applied amount of positive electrostatic charge should guarantee fiber after leaving extension apparatus because of having the like charges effect of repelling each other; Make between the fiber and be separated from each other; Reduce the phenomenon of doubling, tow and teeth, the lace curtaining after being paved into is even, thereby improves the product uniformity.
Because a large amount of electrostatic charge procedure after to lapping is unfavorable, and the nonwoven fabric of static electrification adsorbs dust easily, so at the end of lapping machine lace curtaining Xelminator is installed, the positive electrostatic charge that adds eliminated again.
A kind of static of implementing said method divides silk device, and it is made up of with the electrostatic discharging rod that is installed in 100mm place, extension apparatus inlet top the adjustable electrostatic generator that is arranged in beyond the working site, and adjustable electrostatic generator is connected with lead with electrostatic discharging rod; The length of electrostatic discharging rod should satisfy the length of extension apparatus.
Above-mentioned adjustable electrostatic generator should be exported the high pressure of ten thousand volts of 1-10.
During production, the voltage swing through regulating electrostatic generator is also observed the lapping situation, when the uniformity reaches the best; Fixing this voltage was taken a sample after production a period of time, measured the CV value and compared; Readjust voltage swing again, guarantee the uniformity of whole process of production.
Owing to take technical scheme of the present invention, solved the uniformity problem of the terylene spun-bonded non-weaving cloth that people for a long time thirst for solving, especially to the terylene spun-bonded non-weaving cloth less than every square 100 grammes per square metre, its superiority looms large more.
Description of drawings
Fig. 1 is the sketch map that static of the present invention divides silk device;
Fig. 2 is the sketch map of electrostatic discharging rod of the present invention.
Among the figure: the 1-electrostatic generator; The 2-electrostatic discharging rod; The 3-extension apparatus.
The specific embodiment
The method of the terylene spun-bonded non-weaving cloth uniformity of raising of the present invention; Being in the extension apparatus porch of the production equipment of terylene spun-bonded non-weaving cloth, is that the cooled fiber of melt spinning applies a certain amount of positive electrostatic charge through an electrostatic discharging rod, guarantee fiber after leaving extension apparatus because of having the like charges effect of repelling each other; Make between the fiber and be separated from each other; Reduce the phenomenon of doubling, tow and teeth, the lace curtaining after being paved into is even, thereby improves the product uniformity; End at lapping machine lace curtaining is installed Xelminator;
The static of enforcement said method as shown in Figure 1 divides silk device; It is made up of with the electrostatic discharging rod 2 that is installed in 100mm place, extension apparatus 3 inlet top the adjustable electrostatic generator 1 that is arranged in beyond the working site, and adjustable electrostatic generator 1 is connected with electrostatic discharging rod 2 usefulness leads; The length of electrostatic discharging rod 2 should satisfy the length of extension apparatus 3.The structure of electrostatic discharging rod 2 is as shown in Figure 2.
In order to verify the advantage of the inventive method, at random the terylene spun-bonded non-weaving cloth kind below three every square 100 grammes per square metre is tested three groups of data of test such as following table:
Can find out by above form; Add certain electrostatic charge, the uniformity index CV value of product has obvious variation, can observe equally when estimating at the scene; Therefore the uniformity that adds the product behind the electric charge has tangible change, can obtain the better uniformity through the adjustment suitable voltage.
