Process of continuously washing textile web

A process of continuous washing of textile web, comprising:

• introducing a textile web into the lower portion of a wash tower chamber through a pressure seal;
• from the lower portion of the chamber guiding the web to travel progressively upwardly within the chamber in generally zig-zag fashion over and between laterally spaced series of vertically spaced guide rolls within the chamber so that successive sections of the web extend generally horizontally in traveling between the series of rolls;
• in the upper portion of the chamber supplying washing liquid to the web in the upper portion of the chamber and adjacent to the tops of said series of rolls for travel of the washing liquid generally downwardly countercurrent to the generally upward progress of the web;
• guiding the descending washing liquid to travel successively downwardly from roll-to-roll and progressively through the successive ascending web sections;
• maintaining a saturated atmosphere of at least 100.degree.C and a super-pressure of at least one atmosphere within said chamber;
• transferring the washed web out of the chamber from the upper portion of said chamber;
• and
• removing spent washing liquid from the bottom of said chamber.

A process of continuously washing textile web, comprising the steps of:

• guiding a textile web in a closed wash tower chamber to travel in generally zig-zag fashion progressively upwardly between laterally spaced series of vertically spaced guide rolls within the chamber so that successive sections of said web extend substantially horizontally in traveling between the series of rolls;
• supplying washing liquid to the web in the upper part of the chamber adjacent to the tops of said series of rolls to travel generally downwardly countercurrent to the generally upward progress of the web;
• and
• successively washing each web section below said supplying of washing liquid with said washing liquid as the liquid progressively descends from section-to-section of the traveling web, including the step of collecting washing liquid at the undersides of said guide rolls and dipping said textile web sections in said washing liquid as the sections travel into engagement with the rolls.
