Three prevention treatment refers to the treatment of fabrics with water, oil, and dust prevention. Frosted velvet printed sofa fabric is usually composed of fabric and printed materials. In order to protect the quality of the fabric and extend its service life, it can be treated with three prevention measures. Waterproof treatment: Use waterproof spray or soak in waterproof liquid to form a waterproof film on the surface of the fabric. This can prevent water stains from penetrating the interior of the fabric and keep it dry and clean. Anti oil treatment: Use anti oil spray or soak in anti oil solution to form an anti oil film on the surface of the fabric. This can prevent oil stains from penetrating the fabric fibers, prevent stains from leaving behind, and also facilitate cleaning and removal of oil stains. Dustproof treatment: Use dustproof agent or soak in dustproof solution to form a dustproof film on the surface of the fabric. This can reduce the adhesion of dust and debris on the fabric and keep the surface of the fabric clean.
