Abstract: A thickness-adjustable air mattress structure includes an airbag body and an elastic sponge. The airbag body is provided with an air chamber. The elastic sponge is in the shape of a square or long strip and provided in the air chamber. An upper surface of the elastic sponge is fixedly connected to an upper surface layer, and a lower surface of the elastic sponge is fixedly connected to a lower surface layer. The elastic sponge is provided with a plurality of first through-seams and a plurality of second through-seams. The first through-seams and the second through-seams each are provided with a U-shaped, C-shaped, or V-shaped cross-section. When the airbag body is inflated and the elastic sponge is vertically expanded, the first through-seams and the second through-seams are expanded. As the elastic sponge can be vertically expanded, it can have a small thickness to fill the air chamber.

Abstract: A sponge, an air mattress, and a sponge fabrication process are provided. The sponge is provided with cutting seams. When an external force is applied, the sponge is expanded, and gaps are formed. The gaps are equivalent to holes of an existing sponge block formed by a conventional vertical punching method. Compared to an air mattress that requires punching the entire sponge, the air mattress only requires cutting the sponge without punching holes, such that corresponding gaps (i.e., corresponding conventional holes) are formed when the sponge is expanded by an external force. After the sponge is combined with an air mattress body, a corresponding pattern is formed. The sponge avoids waste materials formed by punching holes, and is environmentally friendly.

Abstract: Provided are an inflatable structure, an inflatable product, and a method for manufacturing for an inflatable product. The inflatable structure comprises a first layer and a second layer; a composite material comprises a plurality of filling materials which are sequentially stacked from top to bottom; a reflective layer is arranged between a pair of adjacent filling materials; an upper end of the composite material is connected to the first layer, and a lower end of the composite material is connected to the second layer. The composite material is arranged between the first layer and the second layer of the inflatable structure, and said composite material is respectively stretched by the first layer and the second layer; the stretched filling materials are attached to upper and lower surfaces of the reflective layer like two spring structures; when external vibrations are transmitted to the reflective layer, said vibrations are dampened.

Abstract: A process for manufacturing a non-degumming, seamless and surface-laminated basketball, comprising the steps of: step 1: wrapping the inner bladder by threads, thereby shaping the carcass; step 2: preparing the uncured foamed middle bladder; step 3: preparing the half-finished PU surface-laminated ball; step 4: placing the half-finished leather ball obtained from step 3 into a curing mold; subsequently, curing under low temperature and low pressure via the thermal cross-linking method, thereby forming the cured PU foamed basketball; Step 5: testing the air-holding performance of the PU foamed basketball being cured under a low temperature and mounting the air nozzle, thereby obtaining the finished basketball; by means of the present invention, the prior curing process of the middle bladder and related downstream process can be saved.
