<p>The yarn, having an improved solidity, contains a metal sulfonate with the structure (I), wherein M is Na or K, and a compound A with the following units: -(CH2)y- and/or -O-(Cx1<H>2x1<O)>y1<-, wherein x>1< > 2, y > 20 and x>1<y>1< > 20. The base-dyeable yarn contains from 1.0 to 5.0 mol % of metal sulfonate units and between 0.5 and 12 % by weight of the compound A.</p> |
