An apparatus and method effect cleaning of a grooved applicator cylinder which applies molten size to textile strands, such as spun yarns. A plurality of holding blocks have quadrate-shaped channels formed in one end thereof, and a circular cross-section elongated elastomeric material cord (e.g., silicone rubber having a Durometer of about 50-75) is frictionally received within the channel. The position of the holding blocks with respect to a housing may be individually adjusted utilizing a cam slide having a slanted surface which engages an adjustment screw, tightening of the adjustment screw sliding the holding block toward the cylinder. The elastomeric material of the cord deforms to essentially completely fill the grooves and to wipe unused size, lint and the like from the grooves and adjacent lands, including the bottoms of the grooves, to effect cleaning. The housing is beveled to facilitate flow of removed size thereover.

Textile fabrics are dyed in open widths in a closed, heated environment by spraying a heated dye composition containing a dyestuff dispersed in a non-aqueous, high-boiling solvent, without the dye applicator directly contacting the fabric, directly onto the fabric. The sprayed fabric is held under transverse tension in a heated (350.degree. to 450.degree. F.) environment and further heated while the sprayed dye dispersion migrates, penetrates thoroughly through the fabric and levels substantially evenly across the width of the fabric. Fabrics are thus simultaneously uniformly dyed and uniformly heatset. Apparatus for conducting the process is also disclosed.

Solvent dyeing and heatsetting apparatus

A fluid nozzle assembly is disclosed for dispensing liquid dye onto an underlying fabric in a substantially closed structure provided with an inert gas atmosphere. The assembly includes an elongated rotatable housing provided along its length with a relatively narrow opening or slot. An elongated manifold, provided with a plurality of laterally spaced dispensing nozzles, is concentrically mounted within the housing so that the nozzles are aligned with the slot. The housing and manifold are rotatable from a first operative position where the nozzles are in communication with the interior of the structure, to a second inoperative position where the nozzles are substantially isolated from the interior of the structure so that the nozzles may be removed for maintenance, cleaning or replacement without significant loss of inert gas from the interior of the structure. In an alternative embodiment, a fixed, cylindrical housing is mounted exteriorly and concentrically with respect to the rotatable housing and, when the rotatable housing is rotated to an inoperative position, the manifold may be slidably removed through an end wall of the fixed housing.
