Sažetak
Flax/wool (33/66) and flax/polyester (33/66) blend yarns, spun from short staple flax, were scoured using either conventional or enzymatic scouring methods before bleaching under appropriate conditions for the different blends. The efficacy of the various preparation routes was evaluated using a water droplet absorption test, a vertical wicking test and a thin layer wicking method. Enzymatic scouring proved to be at least as effective as conventional scouring, but addition of ethylenediamine tetraacetic acid (to enhance pectin solubility) resulted in more hydrophobic yarns. Thin layer wicking with n-heptane and formamide, as well as with water, permitted calculation of yarn surface free energy changes associated with scouring and bleaching. It is suggested that when thin layer wicking is applied to yarns (rather than fabric samples) special care is required when winding the yarns onto the support to ensure that samples of uniform and repeatable porosity are presented to the wicking liquids.
