Will non-woven wallpaper be more environmentally friendly than PVC?

Non-woven paper (commonly known as: non-woven fabric) is a kind of weaving without directionality, that is, non-warp and weft woven. The structure is relatively loose and can be easily degraded in nature. Therefore, it is more environmentally friendly compared to PVC. s material.

The comparison of the environmental protection of these two materials is based on the degree of pollution to the environment after they are discarded or the amount of energy (or natural resources) used to reduce these materials. In addition, if you want to talk about the purity of the material itself, PVC, which is a high molecular polymer, is relatively simple; on the contrary, the material of non-woven fabric is rather messy. Non-woven is a weaving method, not the material itself. It can be non-woven with various materials. Finally, it is about VOC emissions. VOC=volatile organic compounds=Volatile organic compounds=formaldehyde, ether, ethanol, etc. Since we are most concerned about formaldehyde, it is simply called formaldehyde emission. Is this thing in the wallpaper? It depends on the specific situation. Are all non-woven materials without VOC, but PVC materials will have it? No.

There is a kind of ink called water-based ink, the additives used in the coloring process are materials such as water and ethanol, which are very environmentally friendly; there is also a kind of ink called solvent-based ink (commonly known as: oil-based ink), the auxiliary agent used in the coloring process is organic Solvents are volatile organic compounds that contain formaldehyde and are not environmentally friendly.

For non-woven materials, because the structure is relatively loose, organic solvents can penetrate into the material, and the process of volatilization of compounds such as formaldehyde is relatively slow. For many manufacturers, especially big brands, this solvent-based ink uses very little. Even if it does, it will add links in the production process to complete VOC emissions during the production process. For PVC materials, because the structure is relatively dense, short-base compounds such as formaldehyde cannot penetrate, so compounds such as formaldehyde adhere to the surface of the PVC material and are easy to volatilize, and the volatilization is basically finished after a few days. In fact, in the process of home decoration, the most feared is not the wallpaper, but the composite board (not solid wood). Because the VOC emission of composite panels is relatively very slow, it takes months or even years.

Therefore, the question of whether it contains formaldehyde or emits formaldehyde. Even if solvent-based ink is used in the wallpaper, don't be afraid, it will no longer be harmful to the human body if it volatilizes. Especially for PVC materials, it volatilizes quickly. There may be a strong pungent smell at once, but it is easy for a few days to be fine.
