ABSORBENT STRUCTURE

A method for evaluating the bunched compression of an absorbent structure is described. The method includes placing an absorbent structure in a tensile tester comprising a first end and a second end, moving the first end and the second end of the tensile tester toward each other such that they compress the absorbent structure along its width, lowering a loading probe that compresses the absorbent structure perpendicular to the absorbent structure, and raising the loading probe and decompressing the absorbent structure perpendicular to the absorbent structure. The loading probe acquires data.

12290427 · 2025-05-06 ·

A reusable textile material for managing a bodily fluids and associated systems and methods are disclosed herein. In some embodiments, the textile material includes a first layer having an inner surface and an outer surface, a second layer in contact with the outer surface of the first layer, and a third layer opposite the second layer from the first layer. In some embodiments, the first layer is configured to draw the bodily fluid through the first layer from the inner surface to the outer surface while dispersing the bodily fluid laterally across the first layer. In some embodiments, the second layer is configured to pull the bodily fluid away from the outer surface and hold the bodily fluid in the second layer. In some embodiments, the third layer is configured to confine the bodily fluid from in the second layer.

ABSORBENT CORE HAVING CHANNELS, AND ABSORBENT ARTICLE WITH ABSORBENT CORE

An absorbent core having a length in a longitudinal direction and a width in a transverse direction, including upper and lower core cover layers and absorbent material sandwiched therebetween, and a pair of channels extending in the longitudinal direction in the absorbent material, each of the channels being free or substantially free from absorbent material and having a channel seal extending therein and joining the core cover layers. For at least one transversal segment of the absorbent core including the channel seals, one core cover layer has a first width between the channel seals, and the other core cover layer has a second width between the channel seals, wherein the first and second widths of the core cover layers are the widths of the core cover layers between the channel seals in an unfolded, flat-out state and wherein the first width is no less than 120% of the second width.

Anti-stain absorption pad for underpants and underpants comprising the same

An anti-stain absorption pad for underpants and an underpants including the same are provided. The absorption pad includes a waterproof layer, at least one absorption layer and two fixing structures; wherein the waterproof layer includes a main body and two inverse-folded parts respectively provided at two opposite sides of the main body; the at least one absorption layer is disposed on the main body, and the at least one absorption layer is used for absorbing a liquid; and the two fixing structures are respectively disposed at the two inverse-folded parts, and fix the two inverse-folded parts on the at least one absorption layer. Therefore, in the present invention, since the fixing structures are covered by the waterproof layer due to the structure of the inverse-folded parts, backflow and secondary leakage of menstrual blood can be avoided, thereby achieving a complete leakproof effect.
