Problems solved by technology
[0006] Therefore, in view of the above-mentioned problems, the present invention proposes an absorbent core, which solves the technical problem that the distribution of water-absorbing polymers in the existing absorbent core is difficult to be uniform when the mold wheel is formed, and also solves the problem of the existing absorbent core after the mold wheel is formed. It is easy to cause technical problems of core hardening when using diamond-shaped embossing for reinforcement

Abstract
The present invention relates to the field of disposable sanitary products, in particular to an absorbent core, which includes a body, the body includes an inner core and toilet paper, grooves are arranged on the body, and raised parts are formed on the inner core. A water-absorbing polymer is arranged in the groove, and the two ends of the inner core are respectively coated with a barrier dust-free paper, and each barrier dust-free paper seals one end of each groove, and the width of the groove is the same as the width of the raised part. The ratio is 1:3-2:3, the width of the groove is 10-20mm, the width of the raised part is 15-30mm, the thickness of the inner core at the raised part is 3-5mm, and the inner core is located at the groove The thickness is 1.5-2.5mm. It solves the technical problem that the water-absorbing polymer is difficult to distribute evenly when the existing absorbent core is formed by the mold wheel, and also solves the technical problem that the core body is easily hardened when the diamond-shaped embossing is used for reinforcement. And based on the same inventive concept, a molding process of the absorbent core is proposed.
Description
technical field [0001] The invention relates to the field of disposable sanitary products, in particular to an absorbent core and a molding process thereof. Background technique [0002] At present, in the field of disposable hygiene products, the absorbent core is a relatively core product, and its absorption performance, cost, and structural performance often determine the success or failure of its market competition. Existing absorbent cores are usually formed in a die wheel, which is formed into a specific shape by using wood pulp cotton and water-absorbing polymers in the die of the die wheel, and then released from the die wheel, and then formed by wrapping with surface materials such as toilet paper. The shape after molding is often with concave parts and convex parts, which can not only increase the absorption performance, but also reduce the contact area with the skin. As disclosed in Chinese Patent No.: 200980118308.3, the core includes a base layer, the base laye...
