Abstract
The utility model relates to a composite absorption core comprising at least two layers of fiber aggregates and at least one layer of high-molecular super-absorption resin. The layers of fiber aggregates and the high-molecular super-absorption resin are directly integrated on a hot air bonding machine through a hot air bonding method. According to the utility model, with the hot air bonding method, the at least two layers of fiber aggregates and the at least one layer of high-molecular super-absorption resin are manufactured into the composite absorption core structure, such that soft and fluffy characteristics of the composite absorption core are maintained. The absorption performance of the composite absorption core is excellent, and liquid can be absorbed more freely. Also, when the fiber aggregates are manufactured, bonding is not needed to be carried out on an independent composite absorption core device, and direct bonding and forming are carried out by using hot air on a hot air nonwoven fabric device with a hot air bonding machine. Therefore, a gluing or hot-press bonding production process is eliminated, such that the process is environment-friendly, and production efficiency is effectively improved.
