Problems solved by technology

The antistatic needle-punched non-woven fabric obtained by mixing a certain amount of conductive fibers into the raw materials of the needle-punched non-woven fabric has the characteristics of good antistatic effect and long-lasting, but the manufacturing cost is high, and due to the addition of certain Conductive fiber, the prepared fiber web is a collection of conductive fiber and chemical fiber, which changes the original performance of the fiber web, and is different from the fiber web composed of chemical fiber in performance, so there are some differences in the product application range. certain limit

[0018] (3) Preparation of electrospun conductive fibers

[0019] Before the output fiber web from the roller carding machine enters the web laying machine, an electrostatic spinning device is installed, a spinneret is installed above the fiber web, and a grounded electrode plate is installed below the fiber web to connect the spinning liquid to a high-voltage power supply. The positive electrode, the grounded plate is connected to the negative electrode of the high-voltage power supply, a high-voltage electric field is formed between the spinneret and the grounded plate, and the spinning solution extruded from the spinneret is stretched under the action of the high-voltage electric field to a fiber diameter of Nano-scale ultra-fine fibers, the fiber diameter is less than 1000 nanometers, superimposed on the fiber web, the spinning solution is a composite of polyaniline polymer and polyaniline polymer, with excellent electrical conductivity, the prepared ultra-fine fiber is a ki...

Abstract

The invention relates to a manufacturing method of an antistatic needle fabric, and belongs to the field of textile technology. According to the manufacturing method of the antistatic needle fabric, before a fiber web obtained from a mechanical web forming process enters into a lapping machine, the spinning liquid extruded from an electrostatic spinning nozzle is stretched into a superfine conductive fiber under the function of a high-voltage electrostatic field and is overlapped on the surface of the fiber net; and after a lapping process, a composite fiber web that the conductive fiber layer and the fiber net layer are mutually overlapped is formed. In comparison with the method for manufacturing the antistatic needle fabric by mixing the conductive fiber in the raw materials, the manufacturing method disclosed by the invention has an advantage of not changing the physical and mechanical performances of the fiber net; the produced antistatic needle fabric is good in durability, high in reliability, free from environmental pollution and special finishing process, short in production procedure, low in cost, and applicable to the mass production.

Description

technical field [0001] The invention relates to a manufacturing method of an antistatic needle-punched non-woven fabric, belonging to the technical field of textiles. Background technique [0002] Needle-punched nonwovens are widely used in carpets, automotive interior materials, filter materials and other products with excellent mechanical properties and good permeability. Due to the strong electrification of chemical fibers, when the filter material is used for drying flue gas and dust filtration, due to the low relative humidity, it is easy to generate and accumulate a large amount of electric charge, which is easy to cause harm in filtration, and in severe cases can cause Explosion and fire cause casualties and damage to the workplace. Therefore, non-woven filter materials with antistatic effect should be selected for flammable and explosive dust. In addition, acupuncture non-woven fabrics are prone to generate static electricity due to friction and induction during use...
