An apparatus for supporting a guide roll horizontally within a steamer or like housing wherein the roll is looped partially from the bottom by a length of textile material. The apparatus includes means for suspending the roll at each of its ends via support means that extend through the ceiling of the housing. These support means are vertically controllable to be raised and lowered as required.

Apparatus for supporting a roll looped around by a textile material

An improved process for the continuous dyeing of lengths of textile material that at least partly contain cellulose fibers by the Pad-Steam process wherein the textile material onto which dyestuff has been applied is impregnated with chemical reducing agents including an alkaline solution, is then transported into a steamer for dyestuff-fixation by steaming thereon, is then after-treated by the sequential steps of rinsing with a liquor to remove the reducing agents, oxidizing the dyestuff with a liquor, and soaping and again rinsing the material with a liquor, and then finally drying the material. The improvement in the process comprises effecting the after-treatment steps, at least partially, by forcing the appropriate liquors through the material, especially on the perforated surface of a suction drum.

Process and apparatus for the continuous dyeing of lengths of material

The present disclosure relates to a process for the continuous pad-dyeing or printing of continuous synthetic filament groups with dyestuffs which are set under the influence of heat. More particularly, the present disclosure is directed to a process for the continuous pad-dyeing of synthetic filament groups wherein a heated treatment medium, for example air, is passed through the filament groups which have been printed or padded with the preparations containing the dyestuffs. By drawing heated air through the material being treated a completely uniform drying of the filament groups and also a uniform dyestuff setting is obtained and a migration of the dyestuffs is substantially avoided.

A device for the wet treatment of material lengths, e.g., woven textiles, which comprises several treatment bowls containing treatment liquids, e.g., a washing liquor, one of which is designed as a high efficiency wash bowl with the bowl preceding said high-efficiency wash bowl serving as plain steeping bowl through which the material passes slowly and in folded state through a treatment liquid. A perforated drum wash bowl is used as the high efficiency wash bowl and a J-box means is employed as the steeping bowl.

Device for the wet treatment of material lengths in several treatment

The present disclosure is directed to a process for the production of a textile material length containing filling or bonding agents which are used in the production of synthetic leather which comprises impregnating the textile material with a thermo-sensibilized bonding or filling agent, heating said impregnated bonding or filling agent contact-free to a temperature at which the bonding agent coagulated and subjecting the textile material to subsequent treatment steps.

A process for the continuous heat-setting and shrinking of synthetic fibers in the form of yarns with a given twist and/or in the form of tows with a forced crimp by means of a heated fluid medium with temperatures between 100.degree. and 220.degree.C, characterized in that the fibers are treated in a two-step continuous process, first at temperatures below 100.degree.C in water or saturated steam temperatures, or slightly superheated steam, respectively, and subsequently with air, superheated steam or a superheated steam-air mixture at high temperature conditions between 150.degree. and 220.degree. C.

Process for continuous heat-setting and shrinking of synthetic fibers

The present disclosure is directed to an apparatus for the continuous treatment of fibrous and thread-like materials in the form of slivers, roving or fibrous ribbon wherein uniform treatment, for example, uniform dye application and uniform setting of the dyestuff is effectively achieved.

Apparatus for the continuous treatment of textile material

An apparatus for the continuous steaming, and more specifically shrinking, of fibrous material wherein a fibrous material is transported without tension on conveyor means through absolutely pure and air-free saturated steam within an open steamer housing defining a steam bell, the steam is caused to flow through the material, said saturated steam being produced under said steamer housing and owing to its relatively low specific weight automatically takes the place of the air which in its turn leaves the material owing to its higher specific weight.
