GLOBAL TRENDS IN DYEING

At the AATCC Dyeing Symposium this year four sessions were offered: dye/fiber interactions, trends in carpet coloration, trends in yarn dyeing, and trends in piece dyeing. Improving the dyeability of cellulose, dye penetration of nylon 6 fibers, the use of sulfonated aromatic aldehyde condensation products as stain resist agents, exhaust ..

SHADING IN YARN DYED FABRICS

For the correct mixing of two colors, the quality of threads needed to cover a certain area is not a chance number, but the result of a specific arithmetic formula. The quality of threads needed is made up of an equal number of threads for each color. Therefore, knowing the degree of shading needed, the number of thread per centimeter of ..

Gaston AT Piece Dyeing Machines.

Gaston County Dyeing Machine Company manufactures the Gaston AT20 piece dyeing machine for light weight fabrics, the Gaston AT24 for medium weight knit and woven fabrics, and the Gaston AT28 for medium to heavy weight knit and woven fabrics. Features include a stainless steel kier, liquor circulation pump, lint filter, heat exchanger, and..

The Practical Approach to Controlled Colouration.

Textile chemists use computer color matching systems to control color precisely and achieve right first time dyeing. Factors that affect right first time dyeing include variables in laboratory functions, substrates, process conditions, calibrations, employee skill level, and database management. The most important areas involve maintainin..

Self-Tuning pH Control in Dyeing.

One of the most important parameters in the quality control of dyeing processes is pH. In dyeing, pH exhibits strong nonlinearity and time varying behavior, which complicates conventional quality control and necessitates a control system that adapts to changes in system parameters. A new approach to pH control during dyeing involves self ..

Dye Plants and Dyeing.

An introduction to natural plant dyes for hand dyers provides accurate botanical information about each species, outlines dyeing procedures for practical dyeing with plants, describes how to use the parts of many familiar plants as dyes, and provides historical information about the use of natural dyes. Illustrations are based on traditio..

Ecological and Economical Aspects of reductive Cleaning for Polyester Dyeings.

Reductive cleaning aftertreatment removes oligomers from polyester fibers to improve subsequent spinning, winding, and twisting. Alkaline aftertreatment reduces oligomer build-up, as do limited dyeing times, carriers, increased dosing of dispersant, hot washing, and washing of dyeing machinery. reductive baths can contain sodium hydroxide..

Dyeing Blended Fabrics -- The Ultimate Compromise?

Careful, well-informed dye selection is critical for efficient dyeing of blend fabrics. Factors that affect dye selection and evaluation include homogeneity, absorption in solution, shade area, color value, build-up in blend dyeing conditions, reproducibility, storage stability, compatibility with other classes of dyes and dyeing assistan..

Quality improvement and Autodispensers in Dyeing and Finishing (Part. I).

Computer color matching (CCM) and computer color kitchens reduce the time necessary for dye formulation, which significantly reduces production time, especially for novel textile products and processes. Autodispensers accurately measure dyes and chemicals based on formulations calculated by the CCM. Kurabo's Aukitchen-S100 volumetric auto..
