[0002] Spray-bonded cotton is made of polyester fiber. It is fluffy and soft, flat and crisp, and has good warmth retention. It is an ideal filling material for winter clothes, bedding, and household items. The existing spray-bonded cotton structure generally includes a surface layer, a core layer, and a bottom layer, wherein the surface layer, the core layer, and the bottom layer are composed of a first fiber layer, a second fiber layer, and an adhesive layer stacked in sequence from bottom to top, and the first fiber layer is a recycled fiber layer, the second fiber layer is a low-melting fiber layer, and the adhesive layer is a fiber glue layer. The principle of the formation of this structure of spray-bonded cotton is that fiber glue is sprayed on the fluffy low-melting fiber layer, and the fiber glue has a certain pressure during spraying, and the fiber glue can penetrate into the recycled fiber layer and the low-melting fiber layer, and then after drying and curing, the intersections between the fibers are bonded, so that the spray-bonded cotton can maintain its soft and warm characteristics.
