[0001] The invention belongs to the technical field of wall cloths, and in particular relates to a flame-retardant and anti-fouling seamless embroidered wall cloth and a manufacturing method thereof. Background Art

[0002] Seamless wall covering is a kind of wall covering, also known as seamless wall covering. Lingxiu seamless wall covering is a new wall covering product developed in China in recent years. It is designed according to the height of the indoor wall and can be pasted as a whole according to the circumference of the indoor wall. Generally, wall coverings with a width of 2.7 meters to 3.10 meters are called seamless wall coverings.

[0003] With the improvement of people's living standards and the diversification of aesthetic needs, wall cloth, as an important material for interior decoration, has attracted more and more attention from consumers for its functionality, aesthetics and durability. Traditional wall cloth has certain limitations in flame retardancy and anti-fouling ability, especially in public places and homes, which puts forward higher requirements for the flame retardancy and anti-fouling performance of wall cloth.

[0004] To solve the existing problems, the present invention proposes a flame retardant and anti-fouling seamless embroidery wall cloth and a production method. Summary of the invention
