New process for recycling of poly(acrylic acid)-based superabsorbent polymer (SAP) using a synergistic combination of high shear mixing device and oxidative degradation of SAP to produce poly(acrylic acid) (PAA) useful to recycle pre- and post-consumer SAP.

Recycling of superabsorbent polymer with a hybrid oxidative degradation and high shear mixing

Poly(acrylic acid)-based superabsorbent polymer (SAP) in a feed stream is converted into poly(acrylic acid) (PAA) in an extensional flow device. The total energy used to degrade the SAP into PAA is less than about 50 MJ/kg SAP.

Recycling of superabsorbent polymer with an extensional flow device

Poly(acrylic acid)-based superabsorbent polymer (SAP) and HOin a feed is converted with microwave (MW) irradiation into poly(acrylic acid) (PAA) in the product. The MW total energy used to convert SAP into PAA is less than 50 MJ/kg SAP.

Recycling of superabsorbent polymer via hydrothermal microwave processing

An absorbent article that can be a sanitary napkin. The absorbent article comprises a topsheet joined to a backsheet and has an absorbent core material disposed therebetween, the absorbent core material being a fibrous absorbent material exhibiting on one side thereof discrete raised portions. The raised portions define a continuous network of channels, the channels defining a void region adjacent the topsheet of the sanitary napkin.

A film layer having a micro-textured surface is provided. The film layer has a continuous phase with one or more thermoplastic polymers, wherein at least one of the thermoplastic polymers is a low-modulus polymer having a 2% secant modulus of less than or equal to 140 MPa, and the film has from 10 wt % to 100 wt % of the low modulus thermoplastic polymer. The film layer also has a discrete phase with from 5 wt % to 45 wt % of a thermoplastic starch.

Microtextured films with improved tactile impression and/or reduced noise perception

A multi-layered film comprising at least 3 layers is provided. When a 5 layered film is provided, the film includes a first outer layer having 80% to 100% by weight of one or more polyolefins, a first tie layer having from 5% to 100% by weight of the first tie layer of one or more functionalized polyolefins, a core layer having from 75% to 100% by weight of the core layer of polylactic acid, a second tie layer having from 5% to 100% by weight of second tie layer of one or more functionalized polyolefins, and a second outer layer having from 80% to 100% by weight of the second outer layer of one or more polyolefins, wherein the first tie layer layer is disposed between the first outer layer and the core layer the second tie layer is disposed between the core layer and the second outer layer.

A method of integrating a first fibrous web with a second fibrous web, said method comprising the steps of: a. providing a first absorbent fibrous web material; b. providing a topsheet comprising a second fibrous web material; c. providing an integrating means; and d. integrating said first absorbent fibrous web material and said second fibrous web material by processing through said integrating means. The step of integrating said first absorbent fibrous web material and said second fibrous web material comprises inter-entangling fibers from the first absorbent fibrous web and fibers from the second fibrous web.

Method of making an absorbent core for disposable absorbent article

An improved multilayer polymer film is disclosed. The film may include a first skin layer, a second skin layer, and an intermediate layer between the skin layers. The first, second and intermediate layers may be formed of respective first, second and intermediate polymer compositions. Each layer may have distributed therein particles of titanium dioxide to a weight content of from 6 percent to 14 percent. One or both the second skin layer and the intermediate layer may have distributed therein non-white pigment particles to a weight content of from 0.050 percent to 0.15 percent of such layer(s). The contents and distribution among layers of the pigments may provide for relatively disproportionate improvement of opacity while preserving a neutral white color surface to receive ink-printing, enabling high conformity of printed colors with target colors, and preserving weldability of the film to itself.

Heat sealable multilayer packaging film with improved opacity

A multi-layered film comprising at least 3, preferably at least 5, layers is provided. In the case of a 5 layered film, the multi-layer film includes a first outer layer having 80% to 100% by weight of one or more polyolefins, a first tie layer having from 5% to 100% by weight of the first tie layer of one or more functionalized polyolefins, a core layer having from 75% to 100% by weight of the core layer of polylactic acid, a second tie layer having from 5% to 100% by weight of second tie layer of one or more functionalized polyolefins, and a second outer layer having from 80% to 100% by weight of the second outer layer of one or more polyolefins, and wherein the first tie layer layer is disposed between the first outer layer and the core layer the second tie layer is disposed between the core layer and the second outer layer.
