Abstract

Abstract A continuous process for the wet treatment of textile material in the form of endless ropes and for dwelling the textile a certain period under high temperature (HT) conditions, which comprises introducing the material in curls into the long leg of a vertically positioned, U-shaped tubular tunnel having legs of different length, impregnating the textile under atmospheric pressure with hot treatment liquor that is ejected at a high flow rate by means of spraying nozzles which are positioned at the top and at additional locations further down the descending long leg of the tubular tunnel, conveying the textile along the bent portion of the tubular tunnel under the hydrostatic pressure exerted on the material by the weight of the liquid column in the long leg, conveying the textile from the short leg of the tubular tunnel into a pressure-tight reaction and fixing chamber through at least two pressure locks placed one behind the other at the entrance of the reaction and fixing chamber, allowing the textile to dwell during its passage through the reaction and fixing chamber under the action of a HT vapor atmosphere in stored condition, and finally withdrawing the textile from the reaction and fixing chamber through at least two other pressure locks is disclosed.

A continouos process for the wet treatment of textile material in the form of endless ropes and for dwelling the textile a certain period under high temperature (HT) conditions, which comprises introducing the material in curls into the long leg of a vertically positioned, U-shaped tubular tunnel having legs of different length, impregnating the textile under atmospheric pressure with hot treatment liquor that is ejected at a high flow rate by means of spraying nozzles which are positioned at the top and at additional locations further down the descending long leg of the tubular tunnel, conveying the textile along the bent portion of the tubular tunnel under the hydrostatic pressure exerted on the material by the weight of the liquid column in the long leg, conveying the textile from the short leg of the tubular tunnel into a pressure-tight reaction and fixing chamber through at least two pressure locks placed one behind the other at the entrance of the reaction and fixing chamber, allowing the textile to dwell during its passage through the reaction and fixing chamber under the action of a HT vapor atmosphere in stored condition, and finally withdrawing the textile from the reaction and fixing chamber through at least two other pressure locks.
