20150038929 | ENVIRONMENTALLY FRIENDLY ABSORBENT STRUCTURE - The present invention relates to an absorbent structure, preferably for use in absorbent articles as used in the personal hygiene industry such as feminine hygiene garments, baby diapers and pants or adult incontinence garments. The present invention also relates to an absorbent article comprising such absorbent structure and to a method of manufacturing the absorbent structure. The absorbent structures comprise a carrier layer, an auxiliary layer and an absorbent material there between wherein substantially permanent primary attachments and substantially temporary secondary attachments join the carrier layer and auxiliary layer at least partially together, whereby the substantially temporary secondary attachments are loosened as a result of exposing the absorbent structure to a liquid whereas the substantially permanent primary attachments remain substantially intact. The present invention foresees in the need for improved flexible, thin, lightweight absorbent structures for an absorbent article which overcomes the absorbency problems of the prior art during absorption, distribution and retention of liquids with optimal fit. | 02-05-2015 |
20140296817 | METHOD AND APPARATUS FOR PRODUCING AN ENVIRONMENTALLY FRIENDLY ABSORBENT STRUCTURE - The present invention relates to a method and apparatus for forming a composite structure, preferably for use in an absorbent structure used within the personal hygiene industry, such as for instance feminine hygiene garments, baby diapers and pants and adult incontinence garments. The present invention preferably provides a method and apparatus for depositing particulate material in a desired pattern onto a moving carrier layer and positioning it into a pocketing pattern. The method allows accurate forming of a pre-determined pattern of particulate material clusters at high production speed, with reduced raw material usage and relative low cost. As such method allows manufacturing of absorbent structures being substantially cellulose free and substantially glue free, considered technically, economically and environmentally friendly. The present invention foresees in the need for an improved thin, flexible, lightweight particulate material absorbent structure which overcomes the problems of the prior art having optimal absorption, distribution and retention. | 10-02-2014 |
