The three prevention Naisi velvet plain velvet sofa fabric is a velvet sofa fabric with three prevention functions. The "three protections" refer to waterproofing, anti fouling, and anti tearing. This fabric is made of Ness velvet material, which has a soft and comfortable touch and is suitable for making furniture such as sofas. It has a waterproof function, which can prevent moisture from penetrating into the interior of the fabric, avoiding moisture and deformation of the sofa. This means that even in the event of accidental splashing or small amounts of liquid splashing, water droplets on the fabric will form water droplets that slip off and will not immediately penetrate into the interior of the fabric. It has anti fouling function and can resist the adsorption and penetration of stains. This means that the surface of the fabric has a certain degree of anti fouling coating, making it difficult for stains to adhere to the fabric and also convenient for cleaning and maintenance. It has anti tearing function, and the fabric has high tensile strength, which is not easy to be torn or scratched. This makes the sofa fabric more durable and less susceptible to damage.
