Problems solved by technology

[0006] At present, the research on wall coverings mainly involves the bonding of wall coverings, reducing the content of formaldehyde in wall coverings or the amount of formaldehyde released, etc. However, there are few targeted studies on how to prevent wall coverings from deforming.
In fact, during the use of wall coverings, especially after long-term use, the wall coverings will be deformed, bulged, and warped after the alternating changes of cold and heat in spring, summer, autumn, and winter.
To solve the problem of wall covering warping, in reality, sticky adhesives are often used for bonding, or adhesives are added after warping occurs, and the increase in the content of adhesives will increase the probability of formaldehyde release , or cause the wall covering to change color, affecting the beauty of the decoration

preparation example Construction

[0015] The invention provides a method for preparing a seamless short-fiber non-woven fabric-based embroidered wall covering. The preparation method comprises the following steps: (1) coating the adhesive on the surface of the non-woven fabric, and then laying the short fiber on the surface of the adhesive, and then preliminarily dried to obtain the primary product; (2) the primary product is subjected to the first treatment and the second treatment in sequence to obtain the processed product; (3) the surface of the processed product is finished Embroidery is made, followed by compaction treatment; wherein, the temperature of the first treatment is 53-82°C higher than that of the second treatment.

[0016] Through the above-mentioned technical scheme, the present invention formulates the production process of the wall covering, especially the first treatment and the second treatment are carried out sequentially on the initial product, and the temperature of the first treatment ...

Embodiment 1

[0039] The preparation method of seamless short-fiber non-woven fabric-based embroidery wall covering comprises the following steps:

[0040] (1) Coat the adhesive (polyvinyl acetate resin glue) on the surface of the non-woven fabric (30 filaments), the coating thickness is 25 filaments, and then lay the short fiber (nylon fiber, 35mm in length) on the adhesive On the surface of the mixture, the thickness of the laying is 20 wires, and the laying density is 70 area%, and then preliminary drying (drying at 60°C, drying time is 12h) to obtain the first product;

[0041] (2) The primary product is subjected to the first treatment in turn, the process of the first treatment is carried out under the condition of steam smoking under the steam pressure of 0.02MPa, the temperature of the first treatment is 53°C for 10min, and then the temperature of the first treatment is 5°C / min is cooled to 0°C for the second treatment, the second treatment time is 8min, and the processed product i...

Abstract

The invention discloses a preparation method for seamless chopped-fiber non-woven-fabric-based embroidery wall cloth. The preparation method comprises the following steps: (1) coating the surface of anon-woven fabric with an adhesive, then laying chopped fibers on the surface of the adhesive and carrying out preliminary drying so as to obtain an initial product; (2) subjecting the initial productto primary treatment and secondary treatment successively so as to obtain a treated product; and (3) subjecting the surface of the treated product to finishing and embroidering, and then carrying outcompacting treatment, wherein the temperature of the primary treatment is 53 to 82 DEG C higher than the secondary treatment. The seamless chopped-fiber non-woven-fabric-based embroidery wall cloth provided by the invention has good resistance to alternate cooling and heating; in particular, the wall cloth is free of deformation and warping in practical usage after cycles of the four seasons, i.e., the spring, the summer, the autumn and the winter; so the phenomena of bulging and warping of the wall cloth are greatly reduced. The preparation method has the advantages of simple procedure and easy availability of raw materials.

Description

technical field [0001] The invention relates to wall coverings, in particular to a seamless staple fiber non-woven fabric-based embroidered wall covering and a preparation method thereof. Background technique [0002] Wall covering or wallpaper is a widely used interior decoration material.
