Absorbent core, articles comprising said core, and methods of making

An absorbent core (101) comprising:

• a front portion (122);
• a back portion (124);
• a middle portion (126) positioned between the front portion (122) and the back portion (124);
• and
• a longitudinal axis extending along a length of said core (101) and crossing said front, middle and back portions (122, 126, 124), the absorbent core (101) having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends (102, 103) and at least two opposing sides (104, 105) positioned between said ends (102, 103) characterized in that the absorbent core (101) comprises one or more channels having a first shape when the absorbent core (101) is in dry state and a second shape when the absorbent core is in wet state and in that said first and second shapes are different and in that the absorbent core (101) comprises a single substantially interconnected channel (106) in dry state, and a plurality of distinct channels (206) in wet state,
• wherein the interconnected channel (106) comprises:
• a first channel portion (107) extending substantially along the longitudinal axis proximal to a first side (104) of the core (101);
• a second channel portion (108) extending substantially along the longitudinal axis proximal to a second side (105) of the core (101);
• and
• at least one connecting channel portion (109) in fluid communication with said first and second channel portions (107, 108) and forming a closed end in the form of a U-bend,
• wherein the absorbent core has a first distance (d1) between the first channel portion (107) and the second channel portion (108), a second distance (d2) between the first channel portion (107) and the second channel portion (108), wherein the first distance (d1) is proximal to the front portion (122) of the core (101) and the second distance (d2) is proximal to the back portion (124) of the absorbent core (101), and wherein the first distance (d1) is greater than the second distance (d2).
