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...
