Example Embodiment

[0177] The methods of preparing nonwoven materials described herein can exclude (or can be distinguished from) the following processes: hydroforming (water knitting); hydraulic molding; using air jets; rigid versus elastic (e.g., steel / rubber) embossing; and Use a patterned surface against a flat anvil surface. The method may also exclude (or be distinguishable from) The Procter & Gamble Company's process for preparing "Structural Elastic-Like Films" ("SELF" process). The forming member used herein is different from the forming member used in the SELF film forming process (to form the fluted structure (and the clustered structure)) because the SELF teeth usually have relatively small diameter tips, and the ridges of the mating ring roll are only Adjacent to the SELF teeth on the side, and not the front and back of the teeth.

[0178] Absorbent products

[0179] The three-dimensional nonwoven materials of the present disclosure and their manufacturing methods are discussed above....

Example Embodiment

[0324] Example 1: Single layer

[0325] In Example 1, the material is 50 g / m from Fitesa 2 (gsm) PE / PP sheath / core bi-component spunbond nonwoven material. It was processed by a convex / concave processing tool (forming member) at a depth of engagement (DOE) of 0.155 inches (3.94 mm) at a speed of 25 fpm (7.6 m / min). The teeth on the convex tool have a rounded diamond shape similar to that shown in Figure 21, with vertical side walls and rounded or rounded edges at the transition between the top and side walls of the teeth edge. The teeth are 0.186 inches (4.72 mm) long and 0.125 inches (3.18 mm) wide, with a CD pitch of 0.150 inches (3.81 mm) and an MD pitch of 0.346 inches (8.79 mm). The groove in the mating concave roller also has a rounded diamond shape similar to that of the convex roller, with a gap of 0.032-0.063 inches (0.813-1.6mm) between the rollers, the gap surrounding The periphery of the groove changes slightly.

Example Embodiment

[0326] Example 2: Two layers

[0327] In Example 2, the material is a composite material of two materials, and the two materials are glued together using the same hot melt adhesive applied in a spiral pattern as described in Comparative Example 1. It was processed by the convex / concave processing tool described in Example 1 at a speed of 800 feet per minute (fpm) (24.4 meters per minute) and a DOE of 0.155 inches (3.94 mm). The material layer in contact with the convex roller is a 20 gsm spunbonded nonwoven material produced by Fitesa, which includes 2.5 denier fibers with the blend of PP and PE described in Comparative Example 1. The material layer in contact with the gravure roll is a 60gsm air-bonded carded nonwoven material produced by BeijingDayuan Non-Woven Fabric Co, LTD (Beijing, China), which includes a 5 denier PE / PET skin / core bicomponent fiber.

Abstract

An absorbent article comprises a liquid permeable three-dimensional material, a liquid impermeable backsheet, and an absorbent core positioned at least partially intermediate the liquid impermeable backsheet and the three-dimensional material. The absorbent core comprises an absorbent material having one or more channels defined therein. The absorbent article may comprise other layers positioned at least partially intermediate the absorbent core and the liquid permeable three-dimensional material that also may comprise one or more channels. Any of the layers of the absorbent article may comprise indicia and/or color. The absorbent articles may have a delta E* of greater than 1, according to the delta E* Test herein.

Description

technical field [0001] The present disclosure relates to absorbent articles having certain ΔE* values ​​according to the "ΔE* Test" described herein. Background technique [0002] Absorbent articles are used to absorb and contain bodily exudates (eg, urine, menses, BM). Absorbent articles are often configured as, for example, diapers, pants, adult incontinence products, or sanitary napkins. Consumers in some markets desire three-dimensional materials on the wearer-facing surface of absorbent articles, such as the topsheet. These three-dimensional materials create depth in absorbent articles and thereby provide the consumer with the impression of better absorbency and reduced exposure of the skin to bodily exudates. Three-dimensional materials also provide improved softness or an improved impression of softness compared to planar materials. However, these better absorbency, reduced skin exposure to body exudates, and impression of softness are not the only attributes desir...
