摘要:
A process for making an embossed web includes providing a precursor web a first forming structure having a plurality of discrete first forming elements and a first pressure source and applying pressure between the first pressure source and the first forming structure to force the precursor web to conform to the first forming elements of to form a first embossed web having a plurality of first discrete extended elements. The first embossed web is then provided between a second forming structure having a plurality of discrete second forming elements and a second pressure source and pressure is applied between the second pressure source and the second forming structure to force the first embossed web to conform to the second forming elements to form a second embossed web having a plurality of second discrete extended elements. The resulting embossed web has a plurality of first and second discrete extended elements.

摘要:
Environmentally degradable molded or extruded articles comprising a blend of polyhydroxyalkanoate copolymer and an environmentally degradable thermoplastic polymer or copolymer are disclosed. Such compositions provide annealing cycle times to form molded or extruded articles that are less than annealing cycle times to form a molded or extruded article lacking the environmentally degradable thermoplastic polymer or copolymer.

A method of making an absorbent core for use in an absorbent article. The method comprising the steps of: a. providing a first absorbent fibrous web material; b. providing a second absorbent fibrous web material; c. providing a pair of rolls forming a nip through which the first and second absorbent fibrous web materials can be processed, the pair of rolls being selected from the processes consisting of, ring rolling, SELF, micro-SELF, and rotary knife aperturing; d. deforming portions of the first absorbent fibrous web material by processing through the pair of rolls; e. deforming portions of the second absorbent fibrous web material by processing through the pair of rolls; and f. combining the first and second absorbent fibrous web materials to form the absorbent core.

摘要:
Environmentally degradable molded or extruded articles comprising a polyhydroxyalkanoate C4C6 copolymer composition having short annealing cycle times are provided. Such short annealing cycle times are achieved by compositions having a percentage of C6 units of 2-8%. Desirable annealing cycle times are obtained for molded or extruded articles, particularly for tampon applicators.

摘要:
A film which is water-flushable and biodegradable that is particularly useful as a backsheet for disposable absorbent articles, and in particular flushable interlabial catamenial products. The film comprises: (1) a relatively thin water-impervious biodegradable layer to maintain the integrity of the film during use and to minimize or prevent aqueous liquids from penetrating through the film; (2) a relatively thick substantially water-soluble layer adjacent the water-impervious layer to cause the film to lose integrity after the film is flushed; and (3) a relatively thin substantially water-permeable layer adjacent the water-soluble layer to control the rate at which water and other aqueous liquids contact, dissolve and disintegrate the water-soluble 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.
摘要:
An absorbent core material for a disposable absorbent article and an article with at least one absorbent core material. The absorbent core material can be a fibrous airlaid nonwoven web comprising cellulosic fibers and having a first density, and having a plurality of discrete out-of-plane deformations, the out-of-plane deformations having a second density, wherein the second density is less than the first density.
