Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wall cloth, in particular to a color-woven yarn spinning jacquard seamless wall cloth. BACKGROUND

[0002] The wall cloth is colorful, has rich texture, and has various patterns, such as embroidery, hand-drawing, Chinese style, European style, cartoon, rural style, modern style, and engineering style, covering more than 1,000 types of patterns suitable for various places such as bedrooms, dining rooms, living rooms, study rooms, children's rooms, and public places. The surface texture of the wall cloth is concave-convex, and the three-dimensional pattern causes the sound waves to be diffused, soaked, and softly reflected, so that the sound is quickly scattered and the echo is small. The sound-absorbing, sound-damping, and sound-insulating effects of the wall cloth are obviously stronger than those of other types of walls, and the wall cloth is particularly suitable for bedrooms and old people's rooms and is widely used in villas and high-end hotels. It is extremely beneficial to human health and is a truly green and environmentally friendly wall cloth.

[0003] However, in the prior art, when the existing wall cloth is used in an indoor environment, it is in contact with air, and the moisture in the air erodes the wall cloth, causing the wall cloth to mildew and reducing the strength of the wall cloth, which affects the aesthetics of the wall cloth. In addition, in the prior art, the warp and weft of the wall cloth are displaced after being subjected to stress, causing uneven distribution of gaps between the wall cloths, and air cannot pass through the wall cloth uniformly when passing through the wall cloth, which also affects the air permeability of the wall cloth.
