<p>In the field of knitting there is a need for an improved combination yarn which provides greater flexibility in the knitting of coloured garments. A combination yarn (10) comprises an elastomeric core yarn (12) which has a hard covering yarn (14) wrapped therearound in a spiral configuration. The covering yarn (14) defines a plurality of loops (22) which extend laterally from the core yarn (12). The covering yarn (14) includes at least one synthetic mono-polymer filament (18) which has a plurality of amorphous and crystalline regions (24, 28) of polymer chains (26). The polymer chains (26) in the amorphous regions (24) and at least a portion of each crystalline region (28) have a relaxed configuration with low tension between adjacent polymer chains (26).</p> |
