ADVANCES IN COLOR FORMULATION TECHNOLOGY

Macbeth's new spectrophotometer, the Eagle-Eye, uses pulsed xenon light to measure color samples from 20 feet away. The Eagle-Eye quickly measures the color so that ambient light considerations are eliminated while dark colors are adequately illuminated. Other advantages of the Eagle-Eye include the large area of measurement examined and ..

LIGHTFASTNESS IMPROVERS AND PHOTOSTABILIZATION OF TEXTILES

The photodegradation of polyamide fibers used in automative interior trim is discussed. Lightfastness improvers, Cibafast N, and UV improvers for polyamide fibers are explained. Examples demonstrate that the use of light stabilizers during the dyeing process can visibly improve fiber stability and lightfastness for all shades. Stabilized ..

INVESTIGATION OF THE AFTER-RINSING AND WASHING OF FIBER REACTIVE DYES.(Peidmont Section Res. Committee)

A method for studying parameters used to optimize the washoff cycle of fiber reactive dyes was established. The system helps visualize and measure the process, and monitors, compares, and optimizes such variables as temperature, pH, electrolysic concentration. Wetfastness problems were traced to the inefficient removal of unfixed hydrolyz..

HT-PIECE DYEING MACHINE WITH OVERFLOW AND JET NOZZLE SYSTEM

Then's Thenflow HT-piece dyeing machine has vertical loading and unloading and horizontal storage. Some components, particularly the drive and flooding system, were redesigned to dye light- to heavyweight woven fabrics in wool and wool blends. Uniform and reliable dyeing is achieved with the Overflor system. By converting to a conventiona..

SHORT LIQUOR RATIO PIECE DYEING UNIT

Scholl's Colorstar short liquor ratio piece dyeing unit is based on the design of an earlier model, the Subtilo. Colorstar has increased storage capacity, very low liquor ratio, optimal price/capacity ratio, and minimum space requirement. Capacity per storage chamber is 180 to 200 kilograms depending on fabric type. The largest unit has 1..

EFFECTS OF UREA AND OF ANALOGOUS PRODUCTS WHEN DYEING OR PRINTING CELLULOSICS WITH REACTIVE DYESTUFFS

The effect of urea and analogous products on cellulosic dyed or printed with reactive dyes was studied. Any improvement in dye yield with the addition of urea was shown to depend on water solubility, dye reactivity, and dyeing conditions. Urea acted hydrotropically during padding; however, its function during dye fixation could not be def..

JIGGER -- EVOLUTION OF DISCONTINUOUS TREATMENT

Mezzera's Jiggers for cotton and silk dyehouses come in four models (VGJ, VGM, VGSO, and VGC) with roller widths ranging from 1400 to 3800 millimeters. Maximum speeds of these jiggers range from 150 meters per minute for the VGJ model to 30 meters per minute for the VGC model. The driving mechanisms for the fabric winding rollers are hydr..

INTERESTING FACTS ON PHYSICAL FUNDAMENTALS OF TEXTILE FINISHING PROCESSES. PART 4.

The transport of dye in the boundary layer of fiber assemblies was examined. Mass transfer mechanisms for flow, diffusion, and adsorption transport were qualitatively characterized. Flow transport depended on the type of dyeing process; diffusion transport depended on the chemical properties of the substrate and dye; adsorption transport ..

DYEING AND FINISHING MACHINERY REVIEW

An alphabetical guide to British knitted garment dyeing and finishing machine suppliers gives details of machine ranges, services, and new developments. Each entry provides an address and telephone number. It available, the fax number, telex number, and United Kingdom agent are also listed.
