ABSTRACT:
A liquid receptacle in the form of a chamber has a slit in one section thereof, the elongated sides of the slit being parallel straight lines. The chamber communicates through another section thereof with means for the supply thereto of a liquid treating composition at a controlled rate. Guide means configures a traveling multi-filament textile yarn in a close-packed monofilamentary layer and directs the so-configured traveling textile yarn under a desired tension and at a right angle over the slit and in contact with the chamber at a point downstream of the slit and in proximity thereto. The minimum length of the slit is equal to the total width of the traveling textile yarn when configured in a close-packed monofilamentary layer; and the width of the slit is between about 0.001 and 0.01 inches.
