Problems solved by technology

Chinese Patent Publication CN1350089A discloses a technology that uses coating finishing to make the fabric antistatic, but adds a scraping adhesive process, and the product obtained after coating does not have waterproof and moisture permeability
Japanese Patent Publication 2004-291420 discloses a coating product with antistatic waterproof and moisture permeability, but it first forms a microporous layer on the base cloth with a wet microporous coating method, and then uses a dry coating The method first forms a layer of non-porous film on the release paper, and then attaches the non-porous film to the microporous layer. This processing method is complex in process, high in operation requirements, and high in cost.

Embodiment 1

[0018] First, the following components by weight are uniformly mixed into a fabric coating primer:

[0019] Hydrophilic polyester polyurethane resin 100 parts

[0020] Isocyanate type bridging agent 1.5 parts

[0021] Acid bridging accelerator 1.2 parts

[0022] 30 parts of toluene

[0023] Butanone 5 parts

[0024] The above-mentioned fabric coating primer is evenly coated on the surface of the pure polyester fabric that has been treated with water in a dry coating method to form a coating; before the coating is dry, it is heated and dried. The heating and drying steps are divided into two steps: low-temperature pre-baking and high-temperature baking. The low-temperature pre-baking temperature is 70°C, and the pre-baking time is 1min; the high-temperature baking temperature is 120°C, and the baking time is 1min. After drying, a coated fabric comprising a non-porous layer of polyurethane is obtained.

[0025] Secondly, the following components by weight are uniformly mixe...

Embodiment 2

[0031] The weight part that is mixed into fabric coating primer is:

[0032] Hydrophilic polyester polyurethane resin 100 parts

[0033] Isocyanate type bridging agent 1.5 parts

[0034] Acid bridging accelerator 1.2 parts

[0035] Conductive mica powder 10 parts

[0036] 30 parts of toluene

[0037] Butanone 10 parts

[0038] The weight part that is mixed into fabric coating top glue is:

[0039] Hydrophilic polyether polyurethane resin (7% swelling rate) 100 parts

[0040] 20 parts of white paint

[0041] Conductive mica powder 15 parts

[0042] 25 parts of toluene

[0043] Butanone 5 parts

[0044] Wherein, the conductive mica powder is flake particles with an average particle diameter of 5.0-9.0 μm.

[0045] All the other are with embodiment 1. After drying, an antistatic waterproof and moisture-permeable coated fabric comprising two polyurethane non-porous layers with a swelling rate of 7% is obtained, and the weight percentage of the conductive mica powder in th...

Embodiment 3

[0047] The weight part that is mixed into fabric coating primer is:

[0048] Hydrophilic polyester polyurethane resin 100 parts

[0049] Isocyanate type bridging agent 1.5 parts

[0050] Acid bridging accelerator 1.2 parts

[0051] Conductive titanium dioxide powder 8 parts

[0052] 30 parts of toluene

[0053] Butanone 10 parts

[0054] The weight part that is mixed into fabric coating top glue is:

[0055] Hydrophilic polyether polyurethane resin (12% swelling rate) 100 parts

[0056] 20 parts of white paint

[0057] Conductive titanium dioxide powder 7 parts

[0058] 25 parts of toluene

[0059] Butanone 5 parts

[0060] Among them, the conductive titanium dioxide powder is needle-shaped particles with an average particle diameter of 0.27 μm and an average length of 5.15 μm.

[0061] All the other are with embodiment 1. After drying, an antistatic waterproof and moisture-permeable coated fabric comprising two polyurethane non-porous layers with a swelling rate of...

Abstract

The invention discloses an antistatic water permeability resistant coated fabric comprising base cloth and a coating layer, wherein the coating layer has the antistatic water permeability resistant function, is a single-layer or multi-layer polyurethane imporous layer of which the swelling rate is 15-30% or a single-layer or multi-layer polyurethane imporous layer of which the swelling rate is less than 15%, wherein the single-layer or multi-layer polyurethane imporous layer of which the swelling rate is less than 15% contains 10-40 wt% of conductive powder. The fabric of the invention has excellent waterproofness, moisture-penetrability, antistatic behaviour and washing durability, can be applied on work clothes of departments, such as metallurgy, petroleum, coal, national defense and the like, can be used for work clothes, gym suits and the like in the harsh external environment such as dry and cold occasions and has great economic benefit and social benefit.

Description

technical field [0001] The present invention relates to a coated fabric. Background technique [0002] Textiles, especially chemical fiber products, due to their own hydrophobicity, are prone to static electricity due to friction and induction during production, processing and use, and the electrostatic charge is difficult to dissipate, which is easy to cause dust adhesion, and clothing entangles the limbs to cause adhesion discomfort; Clothing When putting on and taking off, it is easy to produce acupuncture, electric sparks, and electric shocks, which seriously affect the comfort of wearing it and restrict the development of high-quality, high-grade, and high-performance chemical fiber fabrics; in addition, in some special industries, such as Inflammable, explosive places and electronic industries, etc., may cause serious disasters due to the static electricity of fiber fabrics. At present, the antistatic of textiles basically adopts the following methods: ① fiber graft m...
