Method for processing tubular knitted fabrics in continuous form

Abstract

A method for processing tubular knitted fabrics in a continuous form, wherein the tubular fabric is delivered in a substantially dry condition and the edge portions thereof are engaged for simultaneous conveyance and lateral stretching. In this manner, the fabric is stretched to a uniform, predetermined width. In accordance with the invention, the fabric is maintained free of externally applied moisture during the lateral distension of the fabric. The distended fabric is then discharged onto endless supporting surfaces while the edge portions are disengaged in a zone of predetermined dimensions to accommodate a controlled, lateral relaxation of the fabric. Thereafter, both faces of the laterally relaxed fabric are engaged between the endless supporting surfaces. During the time the fabric is engaged by the endless supporting surfaces, steam is applied over the entire area of the fabric to accommodate further relaxation and adjustment of the fabric. In accordance with the invention, the fabric is held in a controlled, continuous gripping engagement between the endless supporting surfaces throughout the conveyance of the fabric by the surfaces and all during the steaming operation. Moreover, moisture is removed from the supporting surfaces subsequent to the steaming of the fabric and prior to re-engagement of the supporting surfaces with the fabric.
