Quality and Efficiency in the Dyeing Plant.

Then's Airflow AFS system is a breakthrough in dyeing technology. The Airflow AFS is an aerodynamic piece dyeing machine that reduces the time required to bring the liquor to appropriate temperatures by use of heat exchangers and steam injection, and injects fresh water to reduce the temperature quickly during the rinse process. As a resu..

Years Later--Results Still Like Those on the First Day.

At ITMA 1995, Babcock Textilmaschinen GmbH intruduced its Babco-Flex dye padder, which comprises a flexible roller pressed against a full cored roller. To ensure absolute uniform pressure across the entire fabric width, Babcock matched the dimensions of each roller width. Because no moving parts are employed, the rollers are wear-free. Wi..

Effect of Solvent Treatment on Nylon-6 Fibre.

Researchers investigated the treatment of nylon 6 with ethylene glycol to determine the effect of the treatment on dye uptake by the fiber. Variations in ethylene glycol concentrations included 1 percent, 2 percent, 3 percent, and 4 percent. Treatment of the nylon 6 samples with the various ethylene glycol concentrations included temperat..

The Affinity of Direct Dyes for Cellophane Under High Hydrostatic Pressure.

Researchers investigated the dyeing of cellophane with C.I. Direct Blue, 1 Red 2, and Yellow 12 under pressures of up to 600 million pascals at 55 degrees centigrade. Dyeing of the cellophane occurred by rolling the cellophane and immersing it in a solution containing the dye and sodium chloride. The results indicated that the uptake of Y..

Trends in the Laboratory Equipment Colorimetery Specialty Field

ITMA 1995 introduced new trends and developments in laboratory equipment and colorimetry. Dyeing equipment developments include detailed improvements in existing program control, storage, process data documentation, and electronic and measurement equipment, as well as an extension of the number of dyeing stages. Continuous dyeing equipmen..

War on Waste: Meeting New Environmental Standards in Printing

A critique describes technical developments of mechanical finishing and printing machines that were apparent at ITMA 1995. The most important overall trend was design refinements by manufacturers aimed at improving environmental performance. In the printing machine sector, attention focused on an innovative rotary screen printing machine ..

Glimpses of Chemical Processing Machinery in ITMA - 95

New chemical processing machinery and technologies, as presented at ITMA 1995, have developed rapidly. Fabric preparation equipment includes units from Benninger, Kleinwefers, Babcock, and Kusters. Monforts, Burckner, and Krantz are marketing new tenter designs. Dyeing machines by Gaston County, Longclose, Krantz, Laip, and others demonst..

Regeneration of the Textile Industry Waste Waters.

Researchers in Croatia are testing the effectiveness of various treatments for the removal of tensides, dyestuffs, and heavy metals from textile finishing effluents. For heavy metal removal, the investigated treatment processes include ion exchange reactions and absorption with natural aluminosilicates, which contain amorphous silica, act..

Study on Water for Dyeing.

Researchers studied the dyeing properties and effluent problems of textile mill water treatment systems. The study used such materials as alum, ferric, chloride, Evirofloc, and nut shells for the treatment of water samples. Jar test apparatus determined coagulation. A Bio-chem water analyzer kit measured pH, conductivity, and redox potent..

Filtration Techniques Used by the Textile Industry for Recovery of Dyes, Chemicals and Energy.

Continual increases in the costs of chemicals, energy, and water make their recovery critically important. The textile industry uses hyperfiltration and ultrafiltration, first introduced 20 years ago, for recovery, although the use is not yet widespread. Mills that have installed filtration systems have had a return on investment of betwe..
