Description

Flame-retardant needled composite base cloth

Technical Field

The utility model relates to the technical field of base cloth, in particular to a flame-retardant needled composite base cloth.

Background

Curtain cloth and sofa cloth are one of the most familiar textiles in the life of people, are widely used in modern life, are used in living rooms, hotels, office meeting rooms, on vehicles such as moving trains, automobiles, airplanes and other public places, are widely visible at any place, and play roles in curtains and sofas, in particular to curtains, and the purposes of regulating the air and light in the inner space and the outer space and beautifying the inner space are achieved by using the curtains, namely, the curtains have functions and decoration. However, when the fabric is used as the traditional curtain fabric and sofa fabric, the fabric is attractive in appearance, but poor in flame retardance, and has no good elasticity under the conditions of strong stretching and impact facing the outside. Therefore, the composite base cloth with good flame retardant effect and good extensibility is designed.
