Non Woven Felt Fabric can withstand the constant pull of men's force, will not tear, will not affect the use, and ensure the stability of Chiffon Interling in windy areas. Compared with black non-woven fabrics of other materials, the tensile strength of the steel frame is reliable. Our company produces Pp Non Woven Fabric technology for many times. During production, the insulation layer is passed through the quilting machine as a whole. The layers are sewn into a whole, and it is not easy to roll, roll, and fracture during use, which will affect the use of Woven Fusible Interling. The upper layer is covered with a layer of film-coated felt. The film-covered felt is not integral but needs to be needled to avoid water seepage through the needle holes. Around the quilt, turn up the bottom tensile felt and pass the double quilting thread to fix the whole quilt. After that, buttonholes are made every 15 cm. Easy to fix during installation.
