Antistatic wear-resistant non-woven fabric for manufacturing dust-free wiping paper and treatment method thereof

Abstract

The invention discloses an antistatic wear-resistant non-woven fabric for manufacturing dust-free wiping paper and a treatment method thereof. The antistatic wear-resistant non-woven fabric is cellulose filament non-woven fabric of which the surface is coated with an antistatic coating, or spun-laced non-woven fabric formed by combining cellulose staple fibers and polyester staple fibers in different proportions, wherein the antistatic coating is a melamine resin coating combined with an antistatic agent with an active group. The treatment method comprises the following steps of: (1) preparing an antistatic coating solution; (2) coating the antistatic coating solution on non-woven fabric with a dip-coating process; (3) drying the non-woven fabric containing the antistatic coating solution; and (4) packaging the dried non-woven fabric in rolls to obtain the antistatic wear-resistant non-woven fabric. The antistatic wear-resistant non-woven fabric has the advantages of durable antistatic performance, high wear resistance, low probability of fiber breakage by hooking in use and fewer fallen fibers. The treatment process is simple; and the antistatic agent can be firmly combined on the surface of the non-woven fabric without polluting a product.

Description

technical field [0001] The present invention relates to a non-woven fabric for making dust-free wiping paper and its processing method. The dust-free wiping paper made of the non-woven fabric is suitable for the manufacture of liquid crystal display panels, magnetic heads of hard disks, circuit boards, optical lenses and precision instruments And other fields that have antistatic and dust removal requirements on the working surface in a controlled environment. Background technique [0002] Dust-free wiping paper is a kind of non-woven fabric used in clean room wiping operations. It must have the characteristics of fast water absorption, no shedding of fibers, no harmful heavy metals and organic substances, and low solvent leaching. At present, there are three kinds of non-woven fabrics commonly used to make dust-free wipes. The first is a non-woven fabric made of different proportions of cellulose staple fibers (such as viscose fibers) and polyester staple fibers prepared b...

AI Technical Summary

Problems solved by technology

The first is a non-woven fabric made of different proportions of cellulose staple fibers (such as viscose fibers) and polyester staple fibers prepared by the jet spunlace method (spunlace for short), although the non-woven fabric has better water absorption performance. , but the short fiber is easy to fall off during the wiping process, causing pollution to the wiping surface

The second is a non-woven fabric made of chemical fiber filaments, such as PP melt-blown fabric, PP or PET spunbond fabric. Although the long fibers of the non-woven fabric are not easy to fall off, the water absorption performance is poor due to the hydrophobic surface of the chemical fiber.

The third is cellulose long fiber non-woven fabric, cellulose long fiber is not easy to fall off, and has excellent water absorption performance, but the strength of cellulose long fiber is smaller than that of ordinary chemical fiber, and the bonding force between long fibers is weak. , cellulose long fibers are easily broken by hooks, and the wear resistance is poor

For example, the Chinese invention patent whose patent number is 200910110331.X discloses an antistatic antibacterial non-woven fabric, its manufacturing process and a mask made of it. Antibacterial masterbatch and antistatic masterbatch are added to the raw materials of the nonwoven fabric, Co-melted extrusion, stretched into filaments, laid into a net, reinforced to form an antistatic antibacterial non-woven fabric, so that the non-woven fabric has antistatic properties. The non-woven fabric produced by this method has good and long-lasting antistatic properties, but the production The cost is high; in the production process, raw materials such as antibacterial masterbatch and antistatic masterbatch have poor compatibility with non-woven fiber raw materials, which may easily cause the hole in the spinneret to be blocked
