BOPI 02 BR/2024 REPERTOIRE NUMERIQUE 27 packaging applications, especially for perishable goods/ commadities. A key feature of the invention is that the fabric (1A) is made using relatively heavy diner bast yarn (3A) on a flat loom. This avoids the fluff and particulate matter generated during weaving process on a circular loom, which cannot work with the heavy denier yarn used in the present invention. The woven fabric (1A) manufactured using the method and materials disclosed here is more robust and durable than the fabric manufactured on a circular loom. The invention also discloses a bag (1) made from the woven fabric (1A) and a process of making a bag (1) that uses an L-stitch or two longitudinal side stitched (1M), or a U-shaped stitch (IN). ________________________________________ (11) 21409 Consulter le mémoire (51) A61F 13/15 (2018.01); A61F 13/53 (2018.01); B29C 53/00 (2018.01) ; B32B 37/00 (2018.01) (21) 1202300348 (22) 25/08/2023 (54) High-utilization rate absorbent core, production line and production method thereof.

(57) The present invention relates to the technical field of absorbent cores, and specifically relates to a high-utilization rate of absorbent core, production line and production method thereof. Particularly, the absorbent core includes a first zone, a second zone, a third zone and a fourth zone sequentially connected along a length direction and having the same length, wherein the second zone has a width less than a width of the first zone and a width of the fourth zone, respectively; the third zone has a width less than a width of the first zone and a width of the fourth zone, respectively. The core is composed of wood pulp and super absorbent polymers (SAP), which are mixed uniformly. The SAP in the second zone and the third zone has a greater proportion based on the entire SAP than a proportion of the SAP in the first zone and the fourth zone based on the entire SAP. In order to overcome the deficiencies of the prior art, objectives of the present invention is to provide a high-utilization rate absorbent core which can enhance the absorption performance in the middle part of the diapers or training pants, and meanwhile to optimize the shape of the core so as to improve the comfort level at the crotch of the diapers or training pants.
