<p>This is a procedure to improve the feel of yarns and spun fibers, particularly those that have previously spun-dyed or tow-dyed. It is characterized by the fact that in a process of coning, winding, rewinding, shrinking and warping a spindle made of solid softener is applied to the yarn during its longitudinal displacement depositing the material that makes up this solid element along the yarn in a quantity between 0.1 and 1% of the weight of the fiber in the yarn being treated. This solid softening element is made up of a complex mixture of fatty amides and esters, partially quaternized.</p> |
