Process for preparing composite nonwoven wallpaper

Abstract

The invention discloses a process for preparing composite nonwoven wallpaper. The composite non-woven wallpaper is of a three-layer structure including a coated material at the upper layer, a wet-laid nonwoven material at the intermediate layer and a needle-punched nonwoven material at the lower layer. A surface density of the upper layer is 10 to 20g / m<2>; the intermediate layer is prepared by adopting wet forming and a spunlaced or thermo-bonding technology, and has a surface density of 100 to 200g / m<2>; the lower layer is prepared by adopting a carded web forming and a punched or thermo-bonding technology and has a surface density of 300 to 400g / m<2>; the three layers of materials are composited by adopting ultrasonic waves and a spunlaced technology, or the like. The composite non-woven wallpaper disclosed by the invention has excellent mechanical properties, favorable air permeability and dampproof and anti-fouling properties, excellent sound absorption property and certain antibacterial property. According to the process disclosed by the invention, defects that a traditional wallpaper material is likely to be affected by damp, is air-impermeable, and is free of sound insulation and noise reduction and the like are solved by adopting wet forming, punched and other nonwoven machining technologies, such that the composite nonwoven wallpaper is applied more widely.

Description

technical field [0001] The invention relates to a preparation process of a composite non-woven wallpaper. The composite non-woven wallpaper material is suitable for the field of home decoration, including public places such as hospitals, communities, and KTVs. Background technique [0002] At present, there are many kinds of wallpapers on the market, including pure paper wallpapers, PVC wallpapers, resin wallpapers, etc., but these traditional wallpapers generally have disadvantages such as moisture, airtight, non-bacterial, and sound-absorbing effects. The green new environmental protection wallpaper solves the above-mentioned problems. Due to its labyrinth structure and close arrangement of fibers, non-woven wallpaper is not only waterproof and moisture-proof, but also has good air permeability, and has the environmental protection advantages of sound insulation and noise reduction. At the same time, non-woven wallpaper can make the material have functional advantages suc...
