Ultrasound Aided Open Width Washing of Mercerized 100 Percent Cotton Twill Fabric.

Researchers investigated the use of ultrasound to improve conventional washing processes. A series of five experiments to determine the effectiveness of ultrasound in the standard wash box configuration to remove caustic soda mercerized cotton twill fabrics tested two ultrasound tanks and used portable ultrasound units in the wash boxes o..

Dyeing of Cotton Fabric with Reactive Dyes Using Hydrogen Peroxide-Renovated Spent Dye Bath Water.

Researchers attempted to optimize such decolorization process parameters as pH, temperature, peroxide concentration, and ferrous sulfate and investigated the reproducibility of shade depths developed in fresh water and those developed in peroxide renovate

On-Line Monitoring of Reactive Batch Dyeing Exhaustion and Hydrolysis by FIA-HPLC.

An investigation into controlling final shade by real time monitoring and adjusting of controllable state variables (electrolyte concentration, dye concentration, pH, and temperature) developed a flow injection analysis (FIA) system that measured real tim

Use of Homo- and Copolymers of 1-Vinyl-2-methyl-imidazole as Dye Transfer Inhibitors in Powdered Detergents and Textile Additives.

Polymers of 1-vinyl-2methyl-imidazole are effective in inhibiting dye transfer in a variety of detergent types. Useful polymers added to granular detergents have an average molecular weight of 5,000-150,000 grams per mole. Polymers are particularly useful in detergents with densities exceeding 550 grams per liter. Terpolymers with acrylic..

Use of Homo- and Copolymers of 1-Vinyl-2-methyl-imidazole as Dye Transfer Inhibitors in Liquid Detergents and Textile Additives.

Polymers of 1-vinyl-2-methyl-imidazole inhibit dye transfer in a variety of detergent types. Useful polymers added to liquid detergents have an average molecular weight of 3,000-400,000 grams per mole. Polymers are suitable in unstructured and structured aqueous or nonaqueous liquid detergents. Terpolymers with acrylic acid are particular..

Use of Ozone to Renovate Dyebath Water.

An Electric Power Institute Research project evaluated the feasibility of renovating spent reactive dyebath wastewater with ozone. The study used ten dye formulations to determine the effect of dye additives on the rate of color removal of ozone. A single

Developments in Jet Dyeing Machines.

Gaston County Machine Company developed the first jet dyeing machine, which offered increased productivity, improved quality, greater dye reliability, and reduced energy consumption. Fully flooded jet dyeing machines transported fabrics into the storage c

The Dyeing of Wool: Past, Present and Future.

Coloration is an improtant stage in the processing of raw wool fibers. Before the development of synthetic dyes, natural dyes extracted from insects and plants were used to dye wool fibers. These natural dyes required a pretreatment with metallic salts to

The Formic Acid in Textile Industry

Kemira and a Finnish university studied the use of formic acid in the textile industry. Formic acid offers a greater acidifying and neutralizing action than acetic acid. Thus, lower quantities of formic acid achieve the same results. Studies show that formic acid treatment does not compromise fabric properties. Formic acid also offers eco..

Dyeing Properties of Wool Treated with Dry Heat, Super Heat Steam, and High Pressure Steam.

Researchers treated wool fibers and woolen fabrics with dry heat (170 degrees centigrade for 15 minutes), super heat steam (170 degrees centigrade for 15 minutes), and high pressure steam (120 degrees centigrade for 15 minutes). Zeta electric potential and electron spectroscopy for chemical analysis measured the surface electric propertie..
