Problems solved by technology

[0003] The disadvantages of plant fiber wallpaper are: 1. Since the wallpaper is composed of plant fibers, it is easy to be affected by moisture, and is greatly affected by the ambient temperature and humidity. It is easy to absorb moisture and become moldy, and its friction resistance is poor. 10% of the dry strength, so it is easy to expand and break, which is not conducive to the long-term use of family hotels; 2. The wrinkle resistance of the wallpaper is poor, and it is easy to wrinkle during the installation and transfer process, and it is not easy to restore, which affects the overall appearance; 3. The quality of this kind of wallpaper The main component is plant fiber. In the actual application process, the flame retardant effect is poor, which is an unsafe factor in the home decoration environment. In the case of fire, it is easy to ignite other items
[0004] In addition, the existing production process of ordinary wallpaper has the following disadvantages: 1. The scope of application is small, 100% chemical fiber raw materials cannot be used, and fiber raw materials with a length of 8mm cannot be processed; 2. The drying equipment is highly required during the coating process , and it is not conducive to large-scale production, and it is not conducive to changing the internal structural characteristics of the wallpaper itself
3. During inkjet printing of ordinary wallpaper materials, due to the unsuitable ink absorption of non-coating special surface treatment, the ink is easy to bleed and spread during printing, the ink droplets are large, the roundness is poor, the image is rough, there is no sense of layering, and the density is low. Low, poor clarity, not water resistant, slow drying, etc.

Abstract

The invention discloses spunlace non-woven fabric wall paper and a production method thereof. The existing wall paper is almost made from paper, so that the existing wall paper is easily affected with damp, influence caused by temperature and humidity of the environment is great, the existing wall paper absorbs moisture and mould easily and has poor rubbing resistance, and the existing wall paper is not applicable to being directly printed on an ink-jet printer. The spunlace non-woven fabric wall paper disclosed by the invention is characterized by comprising a spunlace non-woven fabric and coatings which are coated on the spunlace non-woven fabric twice, wherein the spunlace non-woven fabric is a product obtained by carrying out spunlace on chemical fibers or functional fibers with the length of 20-65mm and the fineness of 0.7-7dtex. The spunlace non-woven fabric wall paper disclosed by the invention has the following beneficial effects: the strength of the wall paper is effectively improved, the wall paper has less possibility of being affected with damp, and required functional finishing can be carried out; and the defects that non-coating special surface treatment has inappropriate ink absorption, ink is easily permeated and spread during printing, an ink droplet is big, the roundness is poor, an image is rough, no layering exists, density is low, definition is poor, no water tolerance exists and the drying speed is slow can be effectively solved.

Description

technical field [0001] The invention relates to a wallpaper material, in particular to a spunlace non-woven fabric wallpaper and a production method thereof. technical background [0002] Most of the existing wallpaper materials are paper materials. The production process of this kind of wallpaper is to add plant fiber raw materials and water to the hydraulic pulper, dilute with clean water after crushing, put them into the pulp storage tank, pump them into the beater for beating, and then Put it into the pulp storage tank for use; then the pulp is adjusted by the thickness regulator and then dehydrated on the Internet to form a pre-wet paper sheet, which is coated after drying, then dried by the dryer, crimped and packaged, and the next process That is, the coating is dried, inkjet printed, cut, and the final product is formed. [0003] The disadvantages of plant fiber wallpaper are: 1. Since the wallpaper is composed of plant fibers, it is easy to be affected by moisture,...
