BICOMPONENT FIBERS, TEXTILE SHEETS AND THEIR USE Russian patent published in 2012 - IPC D01F8/14 D01F8/06 D01F8/18 B32B5/26 D02G3/04 D02G3/22 D04H13/00 D06M13/00 D06M101/32 D06M101/18 A61F13/15 C08L101/16 

FIELD: textiles, paper.

SUBSTANCE: bicomponent fibers contain aliphatic polyester or a mixture of aliphatic polyesters, which form the first component, and polyolefin or a mixture of polyolefins, which form the second component. Polyolefin contains auxiliary material improving its biodegradation. Textile sheets include these bicomponent fibers and are comparable by mechanical properties to textile sheets based on polyolefin, while they are decomposed more efficiently under the action of microorganisms than the textile sheets based on polyolefin.

EFFECT: enhanced biodegradability, to textile sheets such as nonwoven materials comprising these fibers, which can be used in personal care products.
