AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 1-24 are cancelled.
1. A filamentary core for an elastic composite yarn, comprising:
at least two elastic performance filaments; and
a force shifting mechanism configured to boost a bouncing back force of the filamentary core, said force shifting mechanism defining a predetermined shifting point depending on the rate of elastic elongation of the filamentary core, wherein:
each of the at least two elastic performance filaments is configured to: be stretchable at least about 2 times its package length, and have at least 90% up to 100% elastic recovery after having being released from a stretching of 2 times its package length;
said force shifting mechanism is preset such that, when initiating elongation of the filamentary core, the elastic recovery force applied by the elongated filamentary core is realized by at least one active elastic performance filament of the at least two elastic performance filaments and the other of the at least two elastic performance filaments remains in a passive status according to which said other of the at least two elastic performance filaments essentially does not render a recovery force;
said shifting point is set to be at a predetermined elongation rate of the filamentary core upon which the other of the at least two elastic performance filaments is initiated to become active in applying a recovery force; and
said force shifting point is set for an elongation of the filamentary core of more than 0% or 5% of a package length of the filamentary core and less than 100% of the package length of the filamentary core.
