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...

Embodiment 1

[0022] The antistatic wear-resistant nonwoven fabric is made by coating the surface of the spunlace nonwoven fabric combined with 50% viscose staple fiber and 50% polyester staple fiber by coating the hexamethylolmelamine resin coating combined with an antistatic agent.

[0023] Antistatic wear-resistant non-woven fabric treatment method comprises the following steps:

[0024] (1) prepare antistatic coating solution, at first 0.5% hexamethylol melamine resin, 0.05% malonic acid, 0.1% dodecyl dimethyl hydroxyethyl quaternary ammonium salt and water are made mixed solution, stir Evenly put into the padding tank;

[0025] (2) The antistatic coating solution is coated on the non-woven fabric through a dip coating process, and the scrap rate is controlled at 70%.

[0026] (3) Dry the non-woven fabric containing the antistatic coating solution at a temperature of 60° C. for 10 minutes.

[0027] (4) Packaging the dried non-woven fabric into rolls to obtain a wear-resistant non-wove...
