[0177] The methods of making nonwovens described herein may exclude (or be distinguishable from) the following processes: hydroforming (water braiding); hydromolding; use of air jets; rigid versus elastic (e.g., steel / rubber) embossing; and Use the patterned surface against the flat anvil surface. The method may also exclude (or be differentiated from) The Procter & Gamble Company's process for making "Structural Elastic-Like Films" ("SELF" process). The forming member used herein differs from the forming member used in the SELF film formation process (to form the fluted structure (and the tufted structure)) because the SELF teeth typically have relatively small diameter tips and the ridges of the conforming ring roll are only Adjacent to the SELF teeth on the sides, and not the front and rear of the teeth.

Embodiment 1

[0324] Example 1: Single layer

[0325] In Example 1 the material was 50 g / m from Fitesa 2 (gsm) PE / PP sheath / core bicomponent spunbond nonwovens. It was machined by a male / female tooling (shaping member) at a speed of 25 fpm (7.6 meters / minute) at a depth of engagement (DOE) of 0.155 inches (3.94 mm). The teeth on the male tool have a rounded diamond shape similar to that shown in Figure 21 with vertical sidewalls and rounded or rounded edge. The teeth are 0.186 inches (4.72mm) long and 0.125 inches (3.18mm) wide with a CD spacing of 0.150 inches (3.81mm) and a MD spacing of 0.346 inches (8.79mm). The grooves in the conforming concave rolls also have a rounded diamond shape similar to the shape of the convex rolls, with a 0.032-0.063 inch (0.813-1.6 mm) gap between the rolls around the The perimeter of the groove has changed slightly.

Embodiment 2

[0326] Example 2: Two layers

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