Abstract:
A process and an apparatus for batch treating of textile material such as yarn packages, raw stock, knit goods, muffs or the like by placing the material in an enclosed zone, evacuating the enclosed zone to provide a vacuum therein, and then flooding the evacuated zone with a treating agent by placing the evacuated zone into communication with a second zone having the treating agent therein under a positive pressure. A substantial pressure differential exists between the two zones, and the treating agent flows extremely rapidly through the textile material whereby, at the very outset of the treating process, the treating agent is uniformly distributed over the surfaces of the textile material and substantially in its original concentration and condition. The temperature of the treating agent will depend upon the treatment. The process and apparatus are capable of recycling or reversing the flow of the treating agent through the textile material as and when desired. Examples of treating agents are: dye liquor, scouring liquids, fixing agents, solvents, finishes or the like, or combinations of dye liquor with other treating agents, such as scouring chemicals, salt, and any other desired chemicals.
Abstract:
Apparatus including a rotary upright spindle is placed within a chamber confined by an openable mantle casing in order to extract water or watery liquid from textile pirns mounted thereon by centrifugal effect caused by a high speed axial rotation thereof, subsequent rotation of the spindle at relatively lower speed in combination with a supply pump and a cross valve causing circulation of oiling agent through the textile pirns.

Abstract:
A dyeing apparatus comprising a closed cylindrical container divided by an intermediate bottom into an upper space containing a package of the material to be dyed and a lower space containing a cylinder in which a piston is reciprocable, the inside and outside of the package being connected by passages in the intermediate bottom to chambers above and below the piston, respectively, within the cylinder.
Abstract:
A method for reeled yarn dyeing as accomplished by operating from inside the yarn winding completely devoid of support, expansion means being provided for producing, upon expansion, individual tight-sealed compartments, in which the dye injectors are accomodated, and apparatus for carrying the method into effect.
Abstract:
A machine for washing and/or applying finishing agents onto yarns in form of skeins, which prevents any type of friction to the yarn fibers. The machine substantially comprises one or more cells in each of which is rotatably mounted at least one reel on which the skeins of yarns are disposed. At the upper part of each cell a row of nozzles is provided for spraying the washing or treatment liquid and a longitudinal slot for blowing an air flow drying the yarns. Each reel comprises a number of spokes one half of which are movable and alternately disposed between two adjacent stationary spokes on which are pivotedly and resiliently mounted. An example of a complete treatment cycle of the machine is also given.
Abstract:
Apparatus and method for the treatment of thread or sheet-like fabric with fluids wherein a drum upon which the thread or fabric is supported in a container, and a trough for pre-treatment of the material is associated with the container.
Abstract:
Programmed centrifuge drum to treat thread and sheetlike material wound on the drum according to which selected parts of the material are subjected to treatment fluid passing through areas of the drum jacket according to a desired program; and means for controlling such passage.
Abstract:
An apparatus for wet treating webs of textile material in which the web is passed over and below staggered rollers in a trough adapted to receive treating liquid into which at least some rollers are at least partially immersed while the web material leaving the last roller is wound onto a perforated drum which latter is, relatively to said last roller, pressed against the latter at a substantially uniform pressure during the winding-up operation, said drum being arranged in a housing adapted selectively to be closed completely for independent wet treatment of material on the perforated drum.
