LINEAR FIBROUS FORMATION COMPRISING POLYMER NANOFIBRES, PRODUCTION METHOD AND DEVICE FOR PRODUCTION OF SUCH FORMATION

摘要

The invention relates to the linear fibrous formation (5) comprising the polymer nanofibres (52) which create the coating (521) on surface of the core (511) formed by the supporting linear fibrous formation (51), while at least some of them are caught among fibres of the surface section of this core (511). Method of production of linear fibrous formation (5) comprising polymer nanofibres (52) consists in that, through the spinning space (4) there is guided the supporting linear fibrous formation (51), on which is outside the spinning space (4) a false-twist imparted, so that the supporting linear fibrous formation (51) rotates in the spinning space (4)around its longitudinal axis, and on its surface the polymer nanofibres (52) are deposited, while at least some of them are being caught among the fibers of the supporting linear fibrous formation (51) due to forming and/or elimination of a false-twist and so they create the nanofibrous coating (521) on the core (511) formed by the supporting linear fibrous formation (51), which is with the core (511) connected by means of the nanofibres (52) caught among fibres of the supporting linear fibrous formation (51).
