FISSIONABLE CONJUGATED FIBRE, ITS AGGREGATE AND FIBROUS FORM MADE OF FISSIONABLE CONJUGATED FIBRE Russian patent published in 2011 - IPC D01F8/14 

FIELD: textile industry.

SUBSTANCE: invention includes a polyester wherein fissionable conjugated fibre contains two or more parts of a polyester segment running form the fibre centre to the outer edge of the fibre in cross section configuration. At least one of the two or more parts of the polyester segment running form the fibre centre to the outer edge of the fibre is located on the outer edge of the fibre. At least one of the two or more parts of the polyester segment running form the fibre centre to the outer edge of the fibre is not located on the outer edge of the fibre. The aggregate contains the fissionable conjugated fibre in proportion at least 25% in relation to the total quantity of fissionable conjugated fibres contained in the aggregate. The fissionable conjugated fibre preferably has a cavity.

EFFECT: invention allows to form a fissionable conjugated fibre containing a polyester and polyolefin with excellent characteristics in terms of fissionability and thermal bonding with a polyolefin containing fixing fibre as well as spinning capability, ensuring a fibrous form with high density and good texture.
