Problems solved by technology

[0003] As we all know, as far as the current large-plate slit air drafting is concerned, due to the high spinning speed, the contact and separation process between fibers and air flow, between fibers and fibers, and between fibers and equipment is short, and fibers are easy to produce Doubling, tow, bonding, etc., resulting in uneven distribution of fibers
For some products that require high uniformity, such as flat non-woven fabrics used for reverse osmosis membrane base fabrics, due to the very high uniformity requirements, the current production technology has met other indicators except uniformity, and the uniformity has not yet been resolved. , in order to develop new markets and occupy new fields, as an enterprise, we must strive to improve product uniformity

Embodiment Construction

[0014] The method for improving the uniformity of polyester spunbonded nonwoven fabrics of the present invention is to apply a certain amount of heat to the fibers after melt spinning and cooling through an electrostatic discharge rod at the entrance of the drafter of the production equipment of polyester spunbonded nonwoven fabrics. The positive electrostatic charge ensures that the fibers repel each other due to the same charge after leaving the drafter, so that the fibers are separated from each other, reducing the phenomenon of doubling, tow and sticking filaments, and the net curtain after laying is uniform , so as to improve the uniformity of the product; install a static eliminator at the end of the net curtain of the netting machine;

[0015] like figure 1 The shown electrostatic splitting device for implementing the above method is composed of an adjustable electrostatic generator 1 arranged outside the work site and an electrostatic discharge rod 2 installed at 100mm...

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 [0001] The invention relates to a production technology of polyester spun-bonded nonwoven fabric. Background technique [0002] Polyester spunbonded nonwovens are also called polyester nonwovens. Spunbond technology is a non-woven fabric production technology with rapid development and high technical content in recent years, and it is one of the main methods for processing non-woven fabrics at present. The spunbond method is a method of melt spinning to form a web. Using the spinning principle of chemical fibers, the extruded melt stream is cooled by quenching air during the polymer spinning process to form filaments, which are then laid on The web is formed on the web curtain, and finally processed by the consolidation device to form a spunbonded nonwoven fabric. [0003] As we all know, as far as the current large-slab slit air drafting is concerned, due to the high spinning speed, the contact and separation process between fibers and airflow, between fib...
