Description

Be suitable for breast pad of practicing thrift core material

Technical Field

The utility model relates to the technical field of breast pads, in particular to a breast pad suitable for saving core materials.

Background

The water absorption layer (also called a core) of the existing breast pad is mostly wrapped by dust-free paper and is basically a round fluff pulp layer (generally mixed with high polymer water absorption particles in the fluff pulp). For a specific structure of the breast pad, refer to patent document CN101299936. The core body can be formed by cutting a core body coiled material, and the core body coiled material manufacturing process comprises the steps of sequentially paving a first layer of dust-free paper, a second layer of high polymer water absorption particles (SAP, SAF and the like are selected), a third layer of fluffy non-woven fabric, a fourth layer of high polymer water absorption particles and a fifth layer of dust-free paper (refer to Chinese patent document CN208693620U for details).

The existing breast pad has the following defects: when a user uses the breast pad in daytime, the breast pad is generally in a vertical state, the middle lower part of the core body can be saturated in absorption, and the middle upper end part of the core body is basically in a dry state; in this case, the user generally directly exchanges a new breast pad because if the user chooses to exchange the direction of the breast pad up and down to continue to use, the core body at the lower part of the original middle is attached to the chest of the human body in a wet state, and the user experience is uncomfortable; therefore, most users choose to replace the new breast pad so as to improve the use comfort of the product. In the face of the application scene with higher proportion in the actual situation, how to save the core material is the technical problem to be solved in the field.
