Computer Colour Matching

Researchers developed a computer color matching system to characterize the migration behavior of fibers in binary blended yarns. The system provides numerical values that fabric. The numerical system allows engineers to predict changes in the aesthetic properties of the fabric due to the migration of coarser fibers toward the surface. Res..

Advances in Computer Colour Matching

An overview of recent advances in automated color matching addresses developments in spectrometers and spectrophotometers. The MC-90 spectrometer combines two identical photodetector diode arrays (sample and reference beams) and diffraction grating into a

Developments in Dyes ＆ Application Technology

BASF Corporation recently introduced four new environmentally freindly textile dyes. Its Basilen Navy F-2 RM features a high degree of fixation, excellent wash-out properties, and high lightfastness. Basilen Blue F-BTM homogeneous reactive dye has a combi

Latest Advances in Cotton Dyeing

Papers presented at the Cottech Europe '96 conference focused on new advances in cotton dyeing. Wolfgang A. Strahl of Cotton Incorporated reported that barre color differences decreased as the micronaire differences among yarns knitted together decreased. Yarn twist variations must be kept below 5 percent to prevent bare. BASF and Cotton ..

Fundamentals of Dye Diffusion

Researchers are examining ways to eliminate dye streaking by understanding the mechanisms that limit the thermal mobility of molecule segments in fibers. They are using software to model the diffusional motion of nylon and polyethylene terephthalate chain segments in fibers. A large number of diffusion experiments have show a previously u..

An Investigation into the Use of Supercritical Fluid Technology for Analytical, Process and Environmental Applications in Textiles.

Researchers are studying the use of supercritical fluid technology to process fluids as well as for analytical applications. They successfully used an evaporative light scattering detector (ELSD) to study the dynamics of suppercritical fluid extraction in real time. They interfaced an ELSD directly to a packed column supercritical fluid c..

Argelich, Termes y Cia SA: Airtint Piece Dyeing Machine

Argelich, Termes y Cia SA manufactures the Airtint piece dyeing machine, which is notable for its ability to operate at ultralow liquor ratios. The most important modification to the unit is the replacement of water with air to transport the fabric during dyeing. In dyeing 1 pound of 100 percent cotton, the Airtint uses 2.83 gallons of wa..

Fast Dyeing with Reactive Dyes on Knitted Fabric

Brazzoli's Saturno dyeing machine reduces the time required for reactive dyeing by 35-40 percent. It uses jet dyeing technolgies to increase fabric throughput to 250-300 meters per minute. The Saturno dyeing machine processes 100-150 kilograms per channel. Other improvements include a continous injection washing system with no downtime in..

Aero-Dye Machine for Lyocell Finishing

Krantz Textiltechnik GmbH's Aero-Dye dyeing machine creates a broad range of surface effects on such fabrics as polynosic blend, polyester, microfiber blend, viscose blend, cotton, and Lyocell fabrics. Possible effects include an opalescent look; peach skin, sand, and eggshell finishes; and an extremely soft hand. The Aero-Dye features an..

Scholl: Softglider Dyeing Machine.

Scholl America Incorporated manufactures the Softglider dyeing machine, which hydraulically opens fabric rope to eliminate rope marks. Machine configuration consists of a novel double U shaped design to optimize fabric transport. The outer U serves as the fabric chamber, and the inner U, which is known as the intensive zone, serves as the..
