摘要:
A method of treating textile materials and an equipment for carrying out this method are provided, notably for dyeing miscellaneous textile materials or articles, whether woven, knitted or unwoven, of synthetic, artificial or natural origin and of various configurations. The method comprises a sequence of steps consisting in disposing the textile material to be treated on a support matching the configuration of the textile material and having at least one inner cavity in its peripheral area as well as a pervious surface contiguous to the textile material; hot-impregnating the textile material to be treated by using a dyeing solution forced through the material from the back side to the right side thereof at a predetermined temperature, and rinsing the textile material by means of a rinsing liquid forced through the material from the back side to the right side thereof during a predetermined time and at a predetermined temperature.

Textile fabrics are dyed in open widths in a closed, heated environment by spraying a heated dye composition containing a dyestuff dispersed in a non-aqueous, high-boiling solvent, without the dye applicator directly contacting the fabric, directly onto the fabric. The sprayed fabric is held under transverse tension in a heated (350.degree. to 450.degree. F.) environment and further heated while the sprayed dye dispersion migrates, penetrates thoroughly through the fabric and levels substantially evenly across the width of the fabric. Fabrics are thus simultaneously uniformly dyed and uniformly heatset. Apparatus for conducting the process is also disclosed.
摘要:
An apparatus is described for continuously dyeing textile fabrics. The apparatus may be best described in terms of its operation as follows: The fabric is preheated in a chamber and then impregnated with a bath consisting of dyestuff dissolved in a solvent in another chamber. Then the fabric is treated in a developing chamber where the dyestuff is fixed thereon by evaporation of the solvent. The excess solvent is then eliminated from the fabric in a water vapor atmosphere. The treatment in the developing chamber is effected by passing the fabric continuously and alternately a plurality of times to and from a zone of saturated solvent vapor and a zone of superheated solvent vapor. The solvent in these two zones is substantially the same as the solvent in the bath.

A method for dyeing polyester fibers by contacting the fiber, which may be in the form of loose fibers or staple, filament or texturized yarn, woven or knitted fabric, with a solution of a soluble dyestuff in a suitable solvent, such as a chlorinated solvent, reducing the volume of the solute in contact with the fiber while maintaining the volume of liquid in contact with the fiber substantially constant by addition of a nonsolvent, maintaining the temperature of the fiber and contacting solvent-nonsolvent at a temperature to effect dyeing. The process also includes the procedures for purifying the solvent and nonsolvent to enable their reuse (recycling) in the process economically and reducing the waste material from the process.The process also provides for scouring and/or drying the fiber if such be necessary.

The present disclosure is directed to an apparatus for the treatment of textile materials which comprises a wet-treatment device containing in its first portion a trough-shaped tank which contains a solvent, inlet means for introducing the materials to be treated to the wet-treatment device and into the solvent in a folded state, a sieve drum means subjected to a suction draft rotatably disposed in the second portion of the wet-treatment device, roller means for conveying the material being treated from the trough-shaped tank to the sieve drum means, press means disposed behind the sieve drum means for at least partially removing the solvent from the material being treated, dryer means disposed behind the press means, said dryer means comprising at least one sieve drum means subjected to a suction draft rotatably disposed in a treatment chamber, exhaust means provided at the outlet side of the treatment chamber, said recycle means also communicating with the solvent recovery device for recycling the substantially solvent free treatment medium back to the treatment chamber and outlet means for removing the material being treated from the dryer means.
摘要:
A process and apparatus for producing dyed and cleaned material. A mixture of a dye and a dye carrier is passed through a batch of material to be processed. The dye remaining in the mixture is separated from the dye carrier after it has passed through the material and the dye and the dye carrier are separately stored. Cleaning fluid is passed first through the batch of material which it cleans of loose dye and then through the store of dye so that the cleaning fluid already containing removed loose dye absorbs the stored dye. The cleaning fluid is separated from the dye and stored and the process is repeated using the stored dye carrier mixed with fresh dye and the stored cleaning fluid.
摘要:
Apparatus for the treatment of textile materials in a bath, such as a dyeing bath containing solvents and diluents for the dye, including an enclosure for the dyeing, means for continuously drawing off a fraction of the bath, means for separating the bath components, recycling means for reintroducing the separated portion into the bath, and regulating devices for regulating the volume of the fraction drawn off from the enclosure.

IN THE DYEING OF TEXTILE SUBSTRATES BY THE ACTION OF A DYE LIQUOR COMPRISING A DYESTUFF HAVING AS A VEHICLE AN ORGANIC SOLVENT, A METHOD OF AND AN APPARATUS FOR, PERFORMING THE DYEING ON SUBSTRATE ARRANGED IN A A SEALED TREATMENT VESSEL AND FOR SUBSEQUENTLY REMOVING THE DYE LIQUOR FROM THE SUBSTRATE, WHILST THE LATTER REMAINS IN THE SAID VESSEL, BY THE PASSAGE OF STEAM THROUGH THE SUBSTRATE UNDER REDUCED PRESSURE.
摘要:
Fibrous material in web or filament form, to be dyed or otherwise chemically treated, is successively passed through a plurality of chambers including a treatment chamber in which it is subjected to the spray of a fluid, a drying chamber which may be subdivided into several compartments, and an intervening reaction chamber in which a controlled amount of moisture is added and which may be preceded by a preconditioning chamber provided with temperature-control means. Air is forcibly circulated, with the aid of a primary blower, from a location near the inlet end of the treatment chamber to a point of the drying chamber remote from the treatment chamber whereby this air passes through the interconnected chambers in counter-current to the treated material. Each chamber may also be provided with an individual secondary air path containing a blower for generating a flow which passes only through that chamber in counterflow to the treated material.
