Embodiment 1

[0022] A new local embossing process for non-woven wallpaper is characterized in that the steps are as follows:

[0023] (1) Non-woven fabric pretreatment:

[0024] Brush a layer of pretreatment liquid on the non-woven fabric, and then dry it at 45°C;

[0025] The formula of described pretreatment liquid is:

[0026] 5g / L trehalose, 0.5g / L malic acid, 0.2g / L citric acid;

[0027] (2) Apply PVC to the non-woven backing paper directly to form the required flower shape through the flower shape on the round screen, and then go through the gravure coloring, and then heat up in the oven, the heating temperature is about 200 ° C, the heating time is 3 minutes, and finally it is pressed by the pressure roller Tied to form a partially embossed product.

[0028] Result: Compared with the wallpaper without pretreatment, the texture of the wallpaper is more realistic and delicate, and the life span is extended by 60%.

Embodiment 2

[0030] A new local embossing process for non-woven wallpaper is characterized in that the steps are as follows:

[0031] (1) Non-woven fabric pretreatment:

[0032] Brush a layer of pretreatment liquid on the non-woven fabric, and then dry it at 52°C;

[0033] The formula of described pretreatment liquid is:

[0034] 3g / L trehalose, 0.8g / L malic acid, 0.2g / L citric acid;

[0035] (2) Apply PVC to the non-woven backing paper directly to form the desired flower shape through the flower shape on the round net, and then go through gravure coloring, and heat up in an oven at a temperature of about 200°C, heating time for 2 minutes, and finally pass through the pressure roller Tied to form a partially embossed product.

[0036] Result: Compared with the wallpaper without pretreatment, the texture of the wallpaper is more realistic and delicate, and the life span is extended by 105%.

Embodiment 3

[0038] A new local embossing process for non-woven wallpaper is characterized in that the steps are as follows:

[0039] (1) Non-woven fabric pretreatment:

[0040] Brush a layer of pretreatment liquid on the non-woven fabric, and then dry it at 49°C;

[0041] The formula of described pretreatment liquid is:

[0042] 4g / L trehalose, 0.6g / L malic acid, 0.2g / L citric acid;

[0043] (2) Apply PVC to the non-woven backing paper directly to form the required flower shape through the flower shape on the round screen, and then go through the gravure coloring, and then heat up in the oven, the heating temperature is about 200 ° C, the heating time is 3 minutes, and finally it is pressed by the pressure roller Tied to form a partially embossed product.

[0044] Result: Compared with the wallpaper without pretreatment, the texture of the wallpaper is more realistic and delicate, and the life span is extended by 100%.

Abstract

The invention discloses a new local embossing process of non-woven wallpaper, which is characterized in that the steps are as follows: (1) Non-woven pretreatment: brush a layer of pre-treatment liquid on the non-woven fabric, and then 45‑52 °C drying; the formula of the pretreatment liquid is: 3‑5g / L trehalose, 0.5‑0.8g / L malic acid, 0.2g / L citric acid; (2) Apply PVC to the non-woven The desired flower shape is directly formed on the backing paper, and then it is colored by gravure, and the temperature is raised in an oven at a temperature of about 200°C, and the heating time is 2-3 minutes. Finally, it is pressed by a pressure roller to form a partial embossed product.

Description

technical field [0001] The invention relates to a partial embossing process for non-woven wallpaper, which belongs to the field of wallpaper manufacturing. Background technique [0002] Wallpaper is widely welcomed because of its richness and variety of patterns and the convenience and quickness of use. It is one of the widely used interior wall decoration materials and is very popular among people. With the development of modern society and the advancement of science and technology, people have higher and higher requirements for the aesthetics of interior decoration, and the decoration style that returns to nature, simple and natural is gradually favored by people with high taste. [0003] In the local embossing process of non-woven wallpaper in the prior art, only foam printing can be processed on the base paper such as non-woven fabric, that is, the pattern with concave and convex surfaces, but there is no texture on the pattern, and the three-dimensional effect is relati...
