SAMPLE JIGGER

The Bombay Textie Research Association has developed an automated laboratory jigger capable of handling a fabric sample 10 centimeters wide and 3 to 4 meters long. A special electronic motor drive moves the fabric through the liquor bath at 2.4 meters per minute. The jigger can be separated from the dyeing vessel, making filling and empty..

THIES INTRODUCES LUFT-ROTO DYEING PRINCIPLE

German-based Thies, a manufacturer of dyeing and finishing equipment, is introducing the Luft-Rotor (Air-Roto) jet dyeing machine to the United States. The machine is designed for woven and knitted fabrics with sensitive surface structures. A rotating drum in the center of the machine enables fabric to be safely transported. The Luft-Roto..

SMALL LOTS HELP THE JIGGER TO MAKE A COMEBACK

Kuesters Twin Jig is designed to shorten processing times by using low liquor ratios, which also reduces the quantities and concentrations of dyes, salts, and auxiliaries in effluent. The Twin Jig permits constant liquor ratios and consistent processing conditions from the smallest to the largest batch. For washing processes, the machine ..

ITMA 1991 REVIEW -- DYEING AND FINISHING EQUIPMENT.

A wide range of dyeing and finishing equipment displayed at ITMA 1991 is reviewed. Arioli featured the Minivapo steam ager, the Flash-Ager steamer, and the Uniwash modular open-width tensionless washer. Babcock showed the Super-Sat high-moisture impregnation unit, a multi-purpose wet finishing range and the BTM 2000 single-layer tenter. H..

REDUCING ENVIRONMENTAL POLLUTION IN TEXTILE PRINTING BY CONTROLLED DAMPING IN FRONT OF FESTOON STEAMER

The combination of a rotor damping system and an area weight differential measuring and control unit permits contact-free, low add-on printing in festoon steamers. The area weight differential measuring unit measures moisture add-on and, by traversing the fabric, can monitor the spraying function of individual rotors. The quantity of wate..

TRANSFER OF LABORATORY DYEINGS IN BATCHWISE DYEING PROCESSES

Because corrections to production dyeing are cosity, extra laboratory work to transfer recipes from the laboratory to bulk with greater reliability is justified. Some sources of error and important factors for recipe transfer are discussed. Tonal differen

EXACT VOLUME OF WATER TO BE USED IN JUGGER DYEING

The volume of water used for jigger dyeing depends on fabric weight, the type of dyestuff, and the depth of shade to be produced. The most leveled and brightest shades are achieved with high volumes of water. Dyeing conditions are described for vat, reactive, azoic, and sulfur dyes. For jigger dyeing to be beneficial, the dyer must use ef..

Environmental issues shape dyeing systems.

An international conference dealing with recent developments in dyeing theory and technology was held at the University of Leeds. Many of the presentations at the conference dealt with environmental issues. Individual papers considered the level of chromium in dyebath effluent, the action of Albegal B levelling agent, the use of mass spec..

DYEING MACHINE AIR-FLOW A/D

The Scalvos Diplo dyeing machine is capable of dyeing delicate fabrics, particularly fubular knit fabrics. Any fiber type can be processed. The liquor ratio is 1:5, which increases the dye yield and reproducibility and decreases the consumption of water and chemicals. Transport is tensionless. Water pressure is minimal. The Air-Flow unit ..

NEW GENERATION OF HENRINKSEN JUGGERS

Henriksen has developed a high-speed control for jig dyers that decreases processing time by up to 30 percent. The microprocessor regulates the speed of the taking-up roller to maintain a nearly constant centrifugal force throughout the passage. Jiggers can achieve maximum speeds of up to 200 meters per minute. One of the main features of..
