<p>A system (10) for applying textile treatment compositions to textile materials. A conduit member (12) is provided which includes a passageway (14) having a first end (20), a second end (22), and a medial portion (24) with a constricted (narrowed) region (44). The passageway (14) may include at least one baffle (150) having an opening therethrough. A yarn stand (120) is then moved through the passageway (14). A textile treatment composition (a sizing agent or dye) dissolved in a carrier medium (a supercritical fluid or liquified gas) is thereafter introduced into the constricted region (44), preferably at an acute angle relative to the passageway (14). The carrier medium expands inside the passageway (14) which causes delivery of the treatment composition to the yarn (120). The treated yarn (310) then passes through the baffle (150) (if used) which facilitates drying of the yarn (120). During this process, a carrier gas (200) can be introduced into the passageway (14) to ensure the production of a smooth, dry product.</p> |
