The invention relates to the wet processing in particular of knitted tubular material in the broad tubular state which in a first processing section is led through a fluid bath then inflated to form a balloon section and afterwards led in the broad tubular state through the gap between a pair of squeezer rollers. Within the fluid bath the incoming material in hank form is subjected to twist sensing and if any twist is detected the incoming tubular material is rotated in the region before the first processing section to undo the twist. The completely and stably relaxed and untwisted tubular material leaves this first processing section in a stable broad tubular state and can then be passed in an optimum manner through the succeeding principal processing sections.

Method for wet processing of tubular textile material

The invention relates to a method and to apparatus for stretching tubular material by blowing in compressed air, in which the delivery speed and/or the removal speed of the tubular material are regulated. In this way, a very uniform stretching of the tubular material is achieved without impairing the surface.

Method and apparatus for stretching tubular material

The invention relates to apparatus for the continuous wet treatment of a length of tubular material in which a changing device is provided at the inlet and the arrangement for introducing air into the length of material extends over the entire width of the chamber. Such apparatus also permits full utilization of the machine capacity even with narrow material.

The invention relates to a method and to apparatus for washing material wound on a beam, in which from the time at which a specific degree of cleanness has been reached in the central region of the roll length until the end of the washing process the proportion of the washing fluid coming out of the central region of the roll length is returned directly to the beam. In this way water and energy can be saved on a considerable scale.

The invention relates to apparatus for the wet treatment of a continuous length of textile material, containing a plurality of chambers through which the length of material flows in succession, in which a fluid connecting channel through which the length of material passes in counterflow to the treatment solution is provided in the region between adjacent chambers. This results in a significant improvement in the exchange of material between the solution and the length of material.

Rinsing of textile material is accomplished in a tank having a rinsing zone through which the material passes upwardly from a resting zone. Rinsing fluid is applied to the upwardly moving material exclusively in the rinsing zone and in a quantity greater than that which the material can carry with it during its upward movement.

Method and apparatus for rinsing textile material

The invention relates to a process and an apparatus for spreading a moving web of textile material during a treatment by means of fluid streams directed from the middle to the edges of the web. The side edges of the web are probed by sensors which control the fluid streams directed onto the associated edges of the web. In this way, reliable spreading is obtained with minimal outlay, even with different webs of textile material and under varying working conditions.

Apparatus for spreading a moving web of textile material

At least one nozzle is provided for supplying a stream of air to tubular knitted textile material. A retaining device, including at least one guide roller, is provided for retaining an air bubble formed in the textile material by the air supplied thereto. Means for controlling the air supply comprises a probing device for measuring said air bubble which is separate from and is located ahead of said retaining device, and includes a feeler element in contact with the side of the air bubble which is remote from said nozzle.

Apparatus for the wet treatment of tubular knitted textile material

A tube has a longitudinal slot extending over the entire working width of the apparatus, and at least one cover element is arranged on the side of the fabric web remote from the slotted tube. The cover element extends over the entire length of the slot, and also extends over a substantial portion of the path of the fabric web, immediately preceding the slot, and over another substantial portion of the path of the fabric web immediately following the slot. A guide surface for the fabric web is provided on the same side of the web as the slotted tube, which surface forms with the cover element a flow space for conducting the working fluid, which flow space extends from a point in the path of travel of the fabric web lying substantially ahead of the slot to a point in the path of the web lying substantially beyond the slot.

Apparatus for passing a working medium through a continuously moving

An aqueous solution containing impurities such as size is applied to a textile material and the textile material subsequently is exposed to treatment by an organic. solvent. Between the application of the aqueous solution and the exposure of the material to the solvent, the material is exposed to a saturated steam treatment in which the impurities are dissolved or degraded.

Processes for removing impurities from textile materials

A process for heat-treating and, in particular, for drying and/or fixing a continuously moved fabric web in a treatment unit comprising at least two treatment zones through which the fabric web successively passes, using a hot gas stream recirculated in the treatment unit, a certain quantity of waste gas being continuously removed from the treatment unit and freed from constituents present in it and some of the waste gas thus treated being returned to the treatment unit after reheating, the rest of the waste gas being released into the atmosphere.

Process for heat-treating a fabric web

Water or organic solvent soluble impurities are removed from textile materials at a treatment zone by applying to the material a first liquid capable of dissolving the impurities, following which a second liquid immiscible with the first liquid is applied to the material to expel the first liquid and the dissolved impurities. The two liquids are then separated and the material is removed from the treatment zone and dried without further contact with the first liquid.

Apparatus for treating a web of textile material in a dwell zone comprises means for guiding around a closed circuit a plurality of suspension bars for carrying loops of the web of material. The web is fed downward at a fixed entrance point in such circuit to cause each passing suspension bar to pick up a loop of the web and is withdrawn continuously at a point in such circuit immediately preceding such entrance point.

An endless strand of textile material is initially dyed by transporting it spirally through successive compartments of a vat and simultaneously and separately circulating a homogeneous dye liquor through the compartments individually, and then the textile material is rinsed while continuing to transport it through said successive compartments, by causing a rinsing liquor to flow successively through the compartments in countercurrent to the movement of the textile material.

Process for the wet treatment of endless strands of textile material

Methods of and apparatus for cold dyeing pile fabrics, particularly carpets, wherein dye liquor is first applied to the pile side of the fabric in an amount between 150% and 300% of the material weight, the dye impregnated fabric then being coiled, under tension, into a roll and the roll allowed to stand, all at room temperature. The magnitude of the tensile force applied to the fabric is greater than about 90% of that required to cause dye liquor to emerge from the roll, but is not more than that which enables 5%, at the most, of the liquor to emerge from the roll.
