Effect Of Functional Finishes And Laundering On Textile Materials. Part 2. Characterization Of Liquid Flow.

Finishing and laundering affected the vertical wicking and demand wettability of polyester and cotton fabtics. Durable-press, antistatic, and stain repellent finishing changed the liquid flow characteristcs of the fibers by changeing their surface energy and/or pore characteristics. The results of wicking and wettability tests after finsh..

Efect Of Functional Finishes And Laundering On Textile Materials. Part 1. Surface-Characteristics.

The Wilhelmy technique determined surface properties of polyester and cotton fibers before and after treatment with durale press, fluorocarbon stain repellent, and antistatic-finshes Durable press and stain repellent finished did not produce changes in the wettability of cotton fiber, but increased the wettability of the polyester fibers...

Padder Monitoring.

Pleva's AF310 monitoring system easily fits onto existing dye padders. The AF310 continuously measures and controls dye application alosng the length and width of the padder. It alerts operators to variations in dye pickup and compares preset with actual pickup values, facilitates adjustment of the pad mangle, and automatically corrects s..

Removal And Speciation Of Transition Metal Lons IN Textile Dyeing Wastewater.

Effluent from dyeing can contain heavy metals, including free ionci metal and complexed metal. To study their bioavailability, about which little is known, speciation of these metals is requistie. One method involves the use of chelating agents, which contain paired imidodiacetic acid groups on a strrene divinyl benzene copolymer. The fun..

American Dyestuff Reporter's Process Controls Buyer's Guide features listings for textile wet processing controllers, auxiliary equipment, and monitoring instruments. an alphabetical listing of manufactures and vendors includes compnay addresses (United States sales agents for overses companies), telephone and fax numbers. the names and I..

Litany Of Solved Problems.

A review of troubleshooting strategies used by textile chemists and colorists focuses on solving such problems as shade nonuniformity; spots from airborne dye; warp dyeing streaks, discoloration of whites sewn to navy; garment fading; white blotches on navy polyester; borwn specks in rayon cakes; colored blotches; vertical yellow streak i..

EFFECT OF AFTERTREATMENTS ON DIRECT DYED JUTE FABRICS.

The effect of aftertreatments with coppr sulfate/potassium dichromate and two fixing agents (Ciba-Geigy's Lyofix 2776 and Sandoz's Sandofix WEI) on direct dyed jute fabrics were examined. Fabrics trated with coppr fsulfate/potassium dichromate showed a slight improvement in lightfastness and a decrease in color strength. Fabric streatd wi..

MILLS WILL FACE NEW EFFLUENT CHALLENGES.

Federal environmental agencies are directing increased attention toward the effluents discharged by textile mills. Regulations are concerned with four basic problems: color in effluent, trace quantities of heavy metals, high concentrations of dissolved salts, and low biochemical oxygen demand (BOD)/chemical oxygen demand(COD) ratios. Most..

LOOKING TO TREAT WASTEWATER? TRY OZONE.

Ozone is a strong oxidizing agent and is safer than chlorine for the treatment of wate and wastewater. Oxone not only disinfects, it also kills viruses in wastewater. Unlike chlorine, ozone does not form toxic chlorinated compounds. For organic compounds, the oxidation and decomposition rates for ozone are much faster than for chlorine. O..

REDUCTION OF EFFLUENT LOAD DURING THE DYEING OF COTTON FABRIC.

High processing costs and escalating environmental dangers caused india's cotton fabric finishers to adjust their processing parameters to minimize effluent loads and still anintanin quality dyeing. Their efforts focused on balancing the quantity of water needed to achieve certain saturated shades in vat dyeing versus the quantity of wate..
