Process for rendering wool sliver shrinkproof, and apparatus for performing the process

Abstract From the Canadian patent

The process for rendering wool sliver shrinkproof involves complete wetting of at least one laterally unguided wool sliver with a chlorinating liquor at ambient temperature wherein the liquor is applied to the sliver with a four- to sevenfold excess. The sliver is conducted immediately thereafter through a guide slot, together with the applied excess quantity of liquid; the complete wetting of the fibers of the sliver with the chlorinating liquor is effected in this guide slot by separating the wool sliver from possible air occlusions. Subsequently thereto the sliver is, accompanied by the liquor through a small-volume guide channel to be squeezed out following the chlorine treatment. The …
