摘要:
A device for subjecting web-shaped textile material to a wet pre-treatment in a damper while passing the textile material along a zig-zag path over rollers alternatingly pertaining to one of two substantially parallel vertical rows of rollers, and through a take off or plaiting device. The dry or squeeze-wet textile material is passed through a vacuum and directly subsequently thereto through a treatment bath. Thereupon, the thus treated textile material is withdrawn from the treatment bath and is passed into a damper where it is plaited for from 8 to 20 minutes (abgetafelt).

An apparatus for the wet treatment of fibrous materials includes a container filled with a treatment liquid, a liquid-permeable support for the material arranged with a supporting surface at least partially underneath a first liquid level within the container, and means for providing a second liquid level extending uniformly along the entire length of the immersed supporting surface and underneath said supporting surface of the support.

THE CURING CONDITIONS IN A STEAMING CHAMBER USED IN THE CURING OF DYED MATERIALS ARE CONTROLLED BY MAINTAINING A BODY OF LIQUID IN THE CHAMBER IN EQUILIBRIUM WITH THE CONDITIONS IN THE CHAMBER, MEASURINNG THE TEMPERATURE OF THE BODY OF LIQUID AND THE RATE OF EVAPORATION FROM ITS SURFACE, AND ADJUDUSTING THE RATE OF INTRODUCTION OF STEAM AND THE INDIRECT HEAT INPUT TO THE CHAMBER IN RESPONSE
TO THE MEASUREMENTS OBTAINED. PREFERABLY THE LIQUID WILL BE WATER.
摘要:
In an installation comprising a chain of rods from which woven material in strip form is suspended in folds, the discharge of hot air or steam through a blowing nozzle is subjected to the cyclic action of a regulating device for progressively reducing the nozzle discharge from a predetermined maximum value during commencement of formation of a fold to a zero value after only a fraction of the time required for complete formation has elapsed. The installation is primarily intended for use in steaming machines.
摘要:
An apparatus for the continuous wet treatment of an endless material, such as a textile web, having a certain width and made of textured polyester fabric or knit, includes a vessel or container having a treatment liquor at a liquid level therein, an endless conveying means for transporting the endless material within the container in the form of suspended loops from an inlet to an outlet of the container, a partition vertically arranged within said container for defining a treatment chamber and a liquor recycling chamber separated from each other, said chambers being in communication with one another above as well as below the partition, means for producing liquid circulation from the treatment chamber to the liquor recycling chamber, the liquor being directed from the top portion of the treatment chamber to the bottom portion and then into the liquor recycling chamber, and take-off means arranged at the outlet of the container and being positioned at the liquid level whereby the endless material is transported through said container in a substantially tension-free manner to provide optimum shrinkage of the material therein.
摘要:
A festoon steamer comprising a set of supporting rods travelling through a closed circuit with a horizontal track in which the web is hanging down in loops from said rods, the loops being consecutively formed in a portion of the circuit ahead of said horizontal track and each loop being only picked up by a rod after its completion.
摘要:
Apparatus for treating textiles with steam and the like wherein a chamber is provided for passing textile material during treatment, the lower and upper walls of the chamber being heat conductive for transferring heat into the chamber, a steam dispenser for introducing the steam into the chamber, and means for heating the chamber walls to prevent condensation of steam on the walls.
