Abstract
Textile filaments are treated with chemical solutions during their manufacture and a longevous apparatus is provided to accomplish this treatment. The apparatus is a cylindrical sleeve engaged with a rotating engaging means for a substantial portion of the sleeve length and the sleeve and means are disposed to be contacted with the chemical solution contained by a receptacle. The peripheral surface of the sleeve is disposed in relation to the receptacle so that the sleeve comes in contact with the moving textile filaments. The sleeve can be a graphite, metallic or metallic coated noncorroding material. The sleeve can have a thickness ranging from a foil to a thickness which allows the sleeve to be coated with a metallic coating. The rotatable engaging means can be a noncorroding material such as stainless steel, a thermosetting polymer, graphite or rubber. The rotatable engaging means having mounted thereon the cylindrical sleeve for a substantial portion of length of the cylindrical sleeve can be horizontally disposed in the receptacle, where the receptacle has an opening at one end where the peripheral surface of the sleeve occupies the opening. This occupation can be arranged wh…
