Abstract

DC60 (15/11/43), a hygienic absorbent with a fluid-permeable cover made For placement in close The body of the wearer when this product is in use by the wearer, a liquid barrier barrier made up of So that it turns away from the wearer's body when this product is in use by the wearer. And absorbent structures between the layers This cover and barrier layer Which structure This absorbent will have a The density is equal to between approximately 0.04 g / cm3 and approximately 0.09 g / cm3. Which layer absorbent layer There is approximately 15% of the super-absorbent particles introduced into the process. On basis of weight to weight and which absorbent layer The second has a density equal to between approximately 0.25 g / m3 and approximately 0.5 g / m3, and this second absorbent layer contains more absorbent particles. Notably, imported Co-operate in it at amounts not less than 30% approximately based on weight by weight. Hygienic absorbent with a layer that allows fluid to pass through.
