摘要:
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.
摘要:
Superabsorbent fibers (SAF) in a feed stream is converted with UV irradiation into soluble polymers in a flow system. The UV total energy used to convert SAF into soluble polymers is less than about 50 MJ/kg SAF.
摘要:
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.

摘要:
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.
摘要:
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.
摘要:
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.
