    摘要: The dyeing behavior of a sulfur dyestuff, whether water soluble or water insoluble, is improved by electrolytic reduction. This reduction is performed in a cell in which the dyestuff is used as the catholyte. An ionic agent, such as salt or lye may be used to improve the conductivity of the catholyte. The dyestuff concentration in the cell ranges from about 5 to 50 percent by weight and 10 to 20 percent by weight is particularly effective. A porous clay diaphragm separates the anolyte and catholyte. The anolyte is for example, an aqueous lye or salt solution. The cathode is a material having relatively high hydrogen overvoltage, such as lead and alloy steels. The anode is a noble metal such as platinum or graphite. The catholyte is agitated during the reduction and its temperature is maintained from about 25* to 200* C. and preferably from 50* to 80* C. A current density of about 0.005 to 0.05 A./cm.2 is employed and preferably maintained from 0.01 to 0.04 A./cm.2. The reduction has an energy demand from about 0.5 to 1 kWh./kg. The termination of the reduction of water-insoluble sulfur dyestuff is determined by a spot analysis test. The end of the reduction of water-soluble sulfur dyestuffs is determined relative to hydrogen formation. After the electrolytic reduction has been terminated, the catholyte is stabilized by adding any of a number of suitable reducing agents.

    摘要: There is provided a novel process for the production of flatdrying, dimensionally stable, durable press garments with good abrasion resistance properties. In such process there is no requirement that the textile material from which said garments are made be impregnated with a fiber-setting reagent and precured or postcured in order to obtain a permanent press; rather, said press is obtained by the more economical and desirable method of heating the textile material to a temperature and for a time of from about 180* Fahrenheit for about 6 hours to about 440* Fahrenheit for about 1 second, cutting patterned pieces of fabric, sewing said pieces into a unitary shaped body, and pressing said shaped body for from about 10 to about 90 seconds at a head temperature of from about 300* to about 350* Fahrenheit and an air supply pressure of from about 20 to about 100 pounds per square inch. This process works especially well with fabrics comprised of from about 50 to about 95 percent of polyester. Since the fabrics used in this process contain substantially no fiber-setting reagent, the garments produced via the process of this invention possess excellent abrasion resistance properties.
