[0002] The full name of polyester fiber sound-absorbing board is polyester fiber decorative sound-absorbing board. It is a decorative material with sound-absorbing function made of polyester fiber by hot pressing. Polyester fiber sound-absorbing board has the characteristics of sound absorption and heat insulation, and the material of the board is uniform and solid, elastic, tough, wear-resistant, impact-resistant, tear-resistant, not easy to scratch, and large board width. Because of its decoration, heat preservation, flame retardant, environmental protection, light body, easy processing, stability, impact resistance, and easy maintenance, it has become the first choice of decorative sound-absorbing material for interior decoration. It is widely used in homes, shopping malls, hotels, KTV, theaters, dance halls, auditoriums, multi-function halls, gymnasiums and other public gathering places. At present, the production process of polyester fiber sound-absorbing board generally goes through the following processes: opening - blending - combing - laying nets - needling - oven hot pressing - air cooling - trimming. In order to make the polyester fiber sound-absorbing board have flame retardant properties, it is necessary to add flame retardants. For example, CN106812222B discloses a polyester fiber flame retardant sound-absorbing board one-time molding fully automatic production line, including an opening mechanism, a combing mechanism, a web laying mechanism and a needle punching mechanism connected in sequence, the opening mechanism is provided with a short fiber feed port, the needle punching mechanism is provided with a board discharge port, the board discharge port is connected with a spraying mechanism for applying a flame retardant to the board, the output end of the spraying mechanism is sequentially connected with a pre-drying mechanism for curing the flame retardant on the fiber of the board, a heating mechanism for molding the board, a calendering mechanism and a cold air mechanism, and the board output by the cold air mechanism enters the laser cutting mechanism. The one-time molding method is adopted, there is no energy loss in the intermediate links, the board processing is continuous, the production efficiency is greatly improved, the production cost is reduced, and the molding quality and flame retardant and sound absorbing properties of the board are also ensured. However, in order to meet the needs of polyester fiber sound-absorbing panels of different sizes, it is necessary to cut the two sides of the grey cotton before the spraying mechanism sprays the flame retardant, which will produce grey cotton waste.
