What are the advantages and disadvantages of three beam un woven fabric making machine in China ?
Advantages and disadvantages of non-woven wallpaper: non woven cloth, also known as non-woven cloth and non-woven cloth. A sheet, web, or batt of oriented or randomly arranged fibers bonded to each other by friction, cohesion, or bonding, or a combination of these methods. Paper and woven, knitted, tufted, stitchbonded with stitchbonded yarns and wet felted products ( whether or not such products are needled or not ) are excluded. The fibers may be natural or chemically processed, and may be short fibers, filaments, or fibers formed in situ.
1. The difference between wet nonwoven and wet papermaking is that nonwoven should meet one of the following conditions:
A, fibers with a ratio of length to diameter greater than 300 ( excluding chemically cooked plant fibers ) account for more than 50 % of the mass in the fiber composition; B fibers with a ratio of length to diameter of more than 300 ( excluding chemically cooked plant fibers ) account for more than 30 % of the mass in the fiber composition and have a density of less than 0.4 / cm3.
2. Viscose fibers are not considered to be chemically cooked plant fibers. The non-woven wallpaper has the best air permeability among the three categories of wallpaper, is also quite environmentally friendly, and has no pollution of its own material. This kind of wallpaper dries fastest when it is pasted, so it won’t damp the wall. Another advantage is the convenience of construction, which may not be obvious to the owner.
The so-called pure paper wallpaper is a wallpaper made entirely of paper pulp. It is mainly made of grass, bark and a new type of natural reinforced wood pulp ( containing 10 % wood fiber ). It is an ideal material for environmental protection and low carbon home improvement, and is becoming a new trend of green home decoration.
Advantages: Good environmental performance, not easy to become warped edges, bubbles, no peculiar smell, strong air permeability, and not easy to mold. Moreover, the pattern is mostly made by printing process, so the picture is vivid and the tone is clear.
Disadvantages: The technical difficulty in construction is high. Once the operation is improper, obvious seams will be easily produced. Moreover, due to the influence of the characteristics of the paper itself, it is not easy to make patterns with strong layering or stereoscopic impression ( because the paper is flat, it can only be printed and cannot be made with concave and convex feeling ), and there is also poor water resistance and scrubbing resistance.
The above small edition lists the advantages and disadvantages of the two wallpapers in detail. The following small edition sums up the advantages and disadvantages of the two wallpapers together to help everyone better see the difference between the two wallpapers:
Non – woven wallpaper:
Advantages: Air permeability is the best of the three wallpaper types, and environmental protection is better. Another advantage is that construction is more convenient.
Disadvantages: Because the material is made of plant fiber or chemical fiber, it is not water resistant or scrub resistant.
Paper wallpaper:
Advantages: The most environmentally friendly of the three wallpapers has vivid patterns and clear colors.
Disadvantages: The construction technology is difficult and the obvious joint problem is easy to occur, because it is made of paper material and it is not easy to make patterns with strong layering.
