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.

Adhesive hot-melt formulations with a main polymeric component, of at least one isotactic metallocene butene-1 polymer composition, that has a low viscosity, and that has a bimodal composition, directly obtained during polymerization, in two consecutive and separate reaction steps. Moreover, said hot-melts include less than 5% by weight of at least one viscosity modifier that is not solid at room temperature. Such unusually low level of said additives, surprisingly allows to attain substantially improved levels both of high adhesiveness and cohesion. The adhesive hot-melt formulations include less than 5% by weight of a polyethylene wax or of a blend of polyethylene waxes, that characterized by a highly linear/non-branched structure and by an exceptionally low Polydispersity Index. The presence of such peculiar polyethylene waxes, that are partially incompatible with the butene-1 polymer composition, allows to use the disclosed hot-melt formulations even in the presence of fibrous or perforated substrates.

The present disclosure is directed, in part, to an absorbent article comprising a liquid management system (LMS) and an absorbent core disposed at least partially intermediate a topsheet and a backsheet. The LMS defines one or more channels therein. The one or more channels of the LMS may at least partially overlap or not overlap with channels defined in the absorbent core.

A diaper with urine detection functionalities is provided. The diaper includes a urine isolation layer, an absorbent core layer, and an outer layer. A urine detection device is disposed between the urine isolation layer and the absorbent core layer. The isolation layer has an open end that is embedded in a sleeve of the absorbent core layer. The urine detection device comprises a detection circuit and a test paper composite. The test paper composite includes: a trace element test paper, an antibiotic test paper, and a urine routine test paper. Each test paper is made up of a plurality of test strips for detecting different elements. Each test strip produces results according to a different color indicator scheme.
