Abstract
An apparatus for conducting the continuous washing of printed and dye-fixed, web-shaped textile material, including woven or knitted fabrics, includes a series of textile processing units arranged along a production line. These units include a dwell bath having a conveying means arranged underneath the bath level for textile material deposited in folds, a textile material moistening zone in front of dwell bath, a dewatering means, at least one sieve drum washing bath and a subsequently positioned squeeze means for removing washing liquid from the textile material.
Claims23
An apparatus for continuous washing of printed and dye-fixed, web-shaped textile material including woven or knit fabrics of natural and/or synthetic fibers which comprises feed means for depositing the textile material in folds into a dwell bath;
- conveying means arranged underneath the liquid level in said dwell bath for transporting the textile material in a folded condition from an inlet end through said bath to an outlet end of said bath, said conveying means including two spaced apart endless belts for continuously conveying the textile material in a folded condition between mutually parallel conveying surfaces provided by said belts, said conveying surfaces being disposed underneath the bath level and rotating in the same direction;
- means located at the outlet end of the bath above the liquid level for removing liquid and a film of dye material detachable from said textile material and for withdrawing the textile material from said dwell bath;
- and at least one washing bath unit having sieve drum means located within a washing bath for washing the textile material, said sieve drum means being subjected to forced throughflow of the washing liquid from the outside to the inside of the drum means;
- said means for depositing said textile material in folds including a slide means at the inlet end of the dwell bath for guiding said folds of textile material into a space between said two endless belts and said slide means being movable in a reciprocating fashion whereby the textile material is subjected to longitudinal compacting and relief during transportation through said dwell bath between said two belts.
An apparatus according to claim, further comprises a textile material moistening zone located in front of the dwell bath and in front of said feed means wherein the textile material is exposed on both sides to a cold liquid for moistening said textile material.
An apparatus for continuous washing of printed and dye-fixed, web-shaped textile material including woven or knit fabrics of natural and/or synthetic fibers which comprises feed means for depositing the textile material in folds into a dwell bath;
- conveying means arranged underneath the liquid level and said dwell bath for transporting the textile material in a folded condition from an inlet end through said bath to an outlet end of said bath;
- means located at the outlet end of the bath above the liquid level for removing liquid and a film of dye material detachable from said textile material and for withdrawing the textile material from said dwell bath;
- at least one washing unit having a sieve drum means within a washing bath for washing textile material, said sieve drum means being subjected to forced throughflow of the washing liquid from the outside to the inside of the drum means;
- and a take-off device for the textile material at the outlet of said dwell bath, said take-off device having a rotatable member controlled in its rotating speed by a potentiometer and a pressure sensor arranged at the level of the textile material deposited on the conveying means, said sensor being movable forward and backward above the textile material within said dwell bath.
