NORDSON--POROUS COAT SYSTEM

The Porous Coat System from Nordson offers and alternative coating technology to powder coating, paste dot printing, gravure-wheel coating, flame bonding, and web or film bonding. The Porous Coat System uses an innovative extrusion coating head design to apply 100 percent solid thermoplastic resins. The systems, which applies discontinuou..

STARCH MAY BE STIFF, BUT IT COULD BENEFIT PESTICIDE APPLICATORS

Starch applied to cotton and cotton/polyester apparel can protect people who work with pesticides against contamination. Starch binds with most pesticides so that there is no contact with the skin. Washing then removes the pesticides and starch. Although starch stiffens the fabric, it is more comfortable than many of the designs used in p..

RESEARCH AT THE INTERNATIONAL WOOL SECRETARIAT(IWS)

The latest research and development in the area of wool coloration at IWS includes three areas of differential dyeing: black overdyeing, tone-on-effects, and multicolored effects; Siroprint continuous vigoureux printing, which extends traditional gray vigoureux effects to a wider shade range of navy, brown, and green as well as a wider pr..

ITMA SURVEY 10--DYEING EQUIPMENT

Dyeing equipment displayed at ITMA 1991 offered less innovative technology than was offered by the other categories of machinery. North West Textile Research presented a cost-effective method for dyeing polyester by using liquid carbon dioxide. Jasper offered a new chemical process by which a filter material, which can be regenerated by o..

EVALUATION OF PARAMETERS OF TEXTILE WET PROCESSING AND FINISHING MACHINERY. CHAPTER 16. JET DYEING MACHINE

The design and operation of jet dyeing machines are discussed. A Scholl COMPACT jet dyeing model is used to illustrate principles of machine design and such operational parameters as temperatures, pressures, power requirements, and liquor ratios. The fabric guiding system, jet nozzle construction, door closing, control systems, and fabric..

DYEING AND PRINTING EQUIPMENT DEVELOPMENTS AT IMTA 1991

Dyeing and printing equipment displayed at ITMA 1991 was compatible with Quick response production scheduling. Operating parameters and production sequences could be altered with little effort of expense. Also associated with the trend towards Quick Response, dyeing and printing machine featured greater versatility in terms of fabric batc..

CONTROLS IN PROCESSING OF POLYESTER FABRICS

Process controls for pretreatment, dyeing, printing, and finishing of polyester fabrics are discussed. For each fabric treatment, proper production parameters and the selection of chemicals and auxiliaries are stressed. Specifications for suitable processing water are outlined. For polyester pretreatment, procedures for sizing/desizing, s..

Pushing Efficiency to the Limits

At ITMA 1999, Thies displayed its Eco-Soft Plus dyeing system with rapid fill/drain, 100 percent add tank, rapid unloading, variable parameters for batch optimization, vario nozzle, automatic self cleaning filter, and the CCR Superwash rinsing process. The unit reduces processing times by up to 50 percent. Thies's air stream dyeing machin..

Then: Innovations in Piece and Yarn Dyeing.

Then GmbH's Then-Airflow AFT HT jet dyeing machine is based on the patented aerodynamic system developed for the AFS machine. The AFT HT jet dyeing machine is a two store machine with a 450 kilogram capacity. The Then-DyeNet control system features a touch screen and graphic display for triggering and remote control of all sensors and act..

Dyeing Safely

Researchers investigated whether how-to manuals adequately warned amateur dyers of the potential risk of contact with chemicals commonly used in natural dyeing. In a survey of more than 350 books and articles available through the local public library, only two issued any warning to pregnant women or women of child bearing age. Abstract.
