APPROACHES FOR PRODUCING SIMULATED YARN DYED DENIMS.

There are two methods for producing simulated yarn dyed denims. One method, based on a fabric treatment, yields a chemically modified cotton which, after being dyed, has the appearance of a denim fabric. This material is termed a pseudodenim because only the face of the fabric has a denim appearance. The second method is based on a chemic..

PROCESSING PLANTS--WET PROCESSING.

Three wet phases of the mercerization process were performed : impregnation with caustic soda, reduction, and washing. A discussion of Sperotto Rimar's new MT/12 and MT/12 is presented.

AUTOMATIC DYE AND CHEMICAL DISPENSING.

Automatic dye and chemical dispensing systems offer management a variety of benefits such as holding formulas to exact tolerances, consistent end product, zero defects, elimination of human error, labor costs savings resulting from total automation, reduction in inventory costs, reduced environmental hazards, and many others. A system for..

MACHINES FOR TEXTILE COLORATION. PART 1. APPLICATION BY DYEING.

Uniform dyeing of textiles is achieved with batch dyeing by liquor circulation and fabric movement. Hank and package dyeing, jig and Japanese soft-flow machines introduced in the 1970's are described. Dyeing knit garments and hosiery and problems associated with textured polyester yarns are addressed as well as the principles of continuou..

BEGINNINGS OF PRESSURE DYEING.

The history of pressure dyeing, beginning with the discoveries by Harold J. Walter at Uxbridge and concluding with the recent advances in beam dyeing and jet dyeing, is outlined. 52 refs.

GREEK-MADE LOW LIQUOR DYEING MACHINE.

The Air Flow A/D, from Sclavos, can handle the most sensitive tubular knitted fabrics and can dye delicate wovens under atmospheric conditions. The machine's design incorporates a mechanical system that transports fabric in open form at variable speeds. The drive rollers rotate synchronously with the movement of the fabric, eliminating st..

I-R ROTARY DYER.

Roaches Engineering's Pyrotec infrared rotary dyeing machine features methods for producing dye samples, electronic sensors, programmable temperature control, and a range of dye pot sizes. The TFO/S humidity-controlled steamer and 50L rotary drum are also discussed.

THE BEST JUDGE IS THE CUSTOMER.

In order to evaluate the MCS Pandora dyeing machines, Tibites Srl, who uses eight models for their cotton tubular knits, was approached for an opinion. Reported advantages include: water and energy savings, easy fabric circulation, quick unloading, absolute protection of fabric surfaces, ease in washing at recipe turnover, and shorter dye..

SUCCESS IN FINE GAGE DYEING.

An historical review of Breconshire Dyeworks, a hosiery manufacturer, includes the company's success with using static dyeing machines produced by Cubotex. The Cubogtex machines, developed in Milan in 1983, were first used in Great Britain by the Breconshire firm in 1988. Today, over 150 static dyeing machines, which replace the cabinet, ..

HOW TO EVALUATE DIRECT-DYE FIXATIVES.

An evaluation of commercial fixative must be based on techniques that permit accurate assessment of not only the positive money-value effectiveness of the fixatives, but also the negative effects these products may have on lightfastness. Some of these techniques are illustrated through the use of data generated using a range of commercial..
