Abstract
An applicator for use in applying chemical treatments to textile fibers is described which does not require the presence of a reservoir of the chemical treatment in close proximity to where the textile fibers are treated. The applicator has a rotating cylindrical roll which rotates continuously during application and is in rotatable horizontal attachment with a support means. The rotating cylindrical roll contacts the filaments at one portion one roll while at another portion on the roll a delivery means having a slot and cavity to which there is provided the chemical treatment is in fluid contact with the rotating applicator roll. The chemical treatment flows from the cavity through the slot and onto the rotating applicator roll to contact the textile filaments at another location on the roll. The chemical treatment is supplied to the cavity of the delivery means by a fluid control means which provides a continuous and controlled amount of the chemical treatment to the delivery means. In this manner, the precise amount of chemical treatment needed to treat the textile filaments can be applied to the cylindrical applicator roll to prevent waste of any chemical treatment. The applic…
