Abstract
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 apparatus has a pair of squeeze rolls, the cylinders of which are arranged to be spaced apart to form a guide slot and are rotatably mounted, these squeeze rolls being associated immediately thereabove with spray means to supply the chlorinating liquor necessary for complete wetting.
