Problems solved by technology

[0005] 1. Compared with non-woven paper, its strength is poor and it is easy to deform
[0006] 2. Under the same thickness, the weight is lighter, the density is small, and the covering is not enough. If there are spots or patterns on the wall, it will pass through the spunlace non-woven fabric
[0007] 3. The surface fiber is fluffy, which is not conducive to wallpaper pattern printing

Embodiment 1

[0030] Using 30% by weight of polyester fiber filaments and 70% by weight of polyester fiber short filaments as raw materials, a spunlace nonwoven fabric is made through a spunlace process, and the spunlace pressure is 28 bar. The prepared spunlace nonwoven fabric is soaked in the padding solution, and the padding solution includes the following components in parts by weight: 20 parts of aqueous acrylic lactic acid solution, 10 parts of kaolin, 15 parts of titanium dioxide, 1 part of dispersant, and 0.5 parts of defoaming agent 0.5 parts of antifungal agent, 3.5 parts of water repellent, and 49.5 parts of water. The spunlace non-woven fabric after padding is subjected to surface coating treatment for further shaping. First use the primer medium to sizing the spunlace non-woven fabric once through a 105-mesh garden net. The primer medium includes the following ingredients in parts by weight: 15 parts of water-based acrylic emulsion, 70 parts of water, 5 parts of transparent pow...

Abstract

The invention discloses a method for manufacturing spunlace non-woven wallpaper. The method comprises the following steps: (1) a spunlace process, wherein a polyester fiber filament and a polyester fiber short filament are used as raw materials, and a spunlace non-woven fabric is manufactured by spunlace process; (2) an afterfinishing stage, wherein a padding process is used for the spunlace non-woven fabric obtained in the step (1) impregnated with padding liquid containing aqueous propylene lactic acid liquid; (3) surface coating treatment, wherein the spunlace non-woven fabric obtained in the step (2) is coated with a bottoming medium, sizing is executed by using a 105-mesh round screen, and baking is executed through an oven; then a covering medium is applied, sizing is executed by using a 125-mesh round screen, rolling is executed after baking with the oven, and the imitated 'cashmere cloth' finished product is obtained. The spunlace non-woven fabric manufactured by adopting the method is small in heat deformation, high in strength, small in tensile deformation, strong in hiding property, uniform in whiteness and good in waterproof effect, has a flat fiber surface and is an ideal material for wallpaper.

Description

technical field [0001] The invention relates to wallpaper materials, in particular to a method for manufacturing spunlace non-woven fabric wallpaper. Background technique [0002] Spunlaced non-woven fabrics use polymer fibers as raw materials to form a fiber web layer of a certain thickness through opening, mixing, and carding of the fibers, and then spray multiple high-pressure fine water jets to the fiber web layer, and the water jets pass through the fiber web. After the layer is rebounded by the mesh curtain, the fiber mesh layer is interspersed again. The fibers in the fiber web layer are displaced, interspersed, entangled and cohesive under the action of high-pressure water jets in different directions, so that the fiber web can be reinforced and have a certain strength, and finally the non-woven fabric is formed after finishing. [0003] Compared with traditional non-woven paper wallpaper, spunlace non-woven fabrics are easy to degrade, and the spunlace process only...
