More than in the Beholder's Eye.

An investigation of color focuses on the history of color and examines the color related interrelationships among culture, science, technology, and art. Topics address color theory, colored material degradation, color reproduction, color photography, paint, pigment analysis, and problems in are restoration. The book fails, however, to add..

ATIRA's microprocessor based control and monitoring system for jigger dyeing machines features a dedicated process control programmer; personal computer based data acquisition system; and software modules that operate in a transparent, multitasking environment. Systems designed for manual jig dyeing machines include temperature control, t..

Colour Fading of Textiles during Laundering. D. A. S. Phillips (UMIST - Manchester).

A single cycle stress test (UK-TO) determines the degree of fading of a substrate after multiple launderings in conventional bleach containing detergents. A study using tetra acetyl ethylene diamine as a bleach activator tested 64 vat, sulfur, direct, and reactive dyed cotton fabrics. Vat dyes did not fade. Azoic dyes faded, especially or..

Fabric Faults Emphasized by Dyeing and Finishing Processes -- Part 2.

Fabric pretreatment and finishing processes lead to or emphasize dyeing defects. Such woolen fabric dyeing defects as uneven fabric center and selvage colors arise from such treatment processes as desizing, carbonizing, kier decating, open width washing, drying, raising, shearing, and calendering. Uneven heat distribution in a dryer provo..

Dyeing of Polyester Microfibres and Ultrafine Fibres -- Research Trends.

Since 1970 studies have shown that the small radius of microfibers causes problems in dyeing and reduces colorfastness. The effects of stagnant solution layer surrounding the fibers on the dyeing rate is heater for microfibers than for conventional fibers. Uneven dyeing is attributable to the uneven flow rate of dye liquor through the fib..

Kyung-In Synthetic Corporation manufactures environmentally friendly dyes for the textile, fur, detergent, and paper industries. The company exports 70 percent of its products to overseas markets. Subsidiaries include Eastwell Company Limited, which produces 2,000 tons of dyes annually; Namo Interactive, which develops internet related so..

Ultrasonic Dyeing of Cotton with Reactive Dyes.

An ultrasonic method dyed plain cotton fabric with 92 ends and 54 picks using C.I. Reactive Red 11, C.I. Reactive Blue 4, and C.I. Reactive Blue 21 dyes at various temperatures. K/S values at different shade depths during room temperature dyeing were higher for ultrasonic dyeing than for conventional dyeing. Ultrasonic dyeing increased C...

Photophysical and Photochemical Events during the Photosensitization of Hypocrellin A on a Colloidal CdS Semiconductor.

An experiment investigating the electron transfer from excited Hypocrellin A (HA) into the conduction band of a colloid CdS semiconductor used the dye HA as a sensitizer. CdS colloids quenched the fluorescence emission of the sensitizing dye HA due to electron transfer from the excited singlet state of HA to the conduction band of colloid..

Influence of Fibre Materials on the Course of Occurrence of Fluorescence

An overview of fluorescence addressed the spectral remission curves of nylon, polyethylene terephthalate (PET), and polyacrylonitrile fabrics dyed by fluorescent disperse dyes; fluorescent brightened PET fabrics; and fabrics printed with fluorescent brighteners and fluorescent pigments. The level of fluorescence caused by fluorescent disp..
