SUGGESTIONS FOR ENVIRONMENTALLY FRIENDLY SOLUTIONS OF COLOR KITCHENS AND PROCESS OPTIMIZING FOR TEXTILE COMPANIES OF THE FUTURE.

Dyehouses can achieve acceptable production while taking the steps necessary to protect the environment. In the laboratory, colormetrics and high-performance computer equipment can be used to optimize color reproduction and achieve a high degree of accuracy. Equipment such as the DS-3 dispensing system are computer controlled and much mor..

TECHNICAL AND ECONOMIC CRITERIA FOR SELECTING DYES FOR WOOL

Level dyeings are more difficult to achieve on wool than on other fibers. Three strategies can be adopted: blending stock- and top-dyed wool with batch-to-batch variations; boiling wool with low molecular weight dyes, which results in migration; and controlling the wool's rate of uptake with high molecular weight dyes. Various classes of ..

DISPENSING SYSTEM ENABLES CONTINUOUS QUICK RESPONSE

A state-of-the-art automated liquid dye dispensing system from the Italian company CIR has been installed on the Neochrome production line at the Courtaulds acrylic fiber plant in Grimsby, United Kingdom. The online dispensing system allows for rapid color changes with excellent consistency and reproducibility. The system consists of see-..

COST EFFECTIVENESS, FLEXIBILITY, AND PROCESS REPRODUCIBILITY -- KEY FACTORS IN DYEING/DRYING MECHINERY DEVELOPMENT.

Barriquand-Durand Textile Machine Company, part of the Barriquand Group, produces two main machine ranges: yarn dyeing and drying machines of both the vertical autoclave (Ecostat) and horizontal autoclave (Ecobox) types, and piece dyeing machines, including the traditional Durand range and the most recent developments. The company's effor..

DEVELOPMENTS AND STATE-OF-THE-ART OF TEXTILE PROCESSING.

Textile finishing preparation is a series of cleaning operations to prepare the textile fibers for subsequent dyeing, printing, and finishing processes. Preparatory operations include desizing, scour boiling, alkalizing/mercerizing, and bleaching. The newest preparatory finishng processes and commercial products are reviewed. The developm..

PROCESS CONTROL SYSTEM FOR TEXTILE FINISHING

The application of a process control system to continuous finishing machines is described. The machines are divided into functional zones; control parameters are defined and the number of controllers are determined for each zone. A multiplexer links the controllers and the computer. Minimum software capability includes parameter definitio..

KNIT AND FABRIC FINOSHING

Both knit and woven fabric finishing involve bleaching, dyeing, and finishing. Woven fabric finishing is, however, a far more substantial sector of the textile industry. The processing of knit goods is not as diversified and thus smaller in scope and less important.

ADVANCES IN TEXTILE WET PROCESSING TECHNOLOGY

Recent advancements and trends in wet processing technology, including such areas as fabric preparation, pretreatment, dyeing, printing, and finishing, are discussed. New and improved machine designs and new chemical treatments are considered. The ways in which these technologies improve fabric quality and reduce processing costs are emph..

DYEING AND FINISHING MACHINERY

Dyeing and finishing exhibited at the 1989 OTEMAS is reviewed. Although the trend toward automation was seen in this sector, it is not as strong as in weaving and knitting. Problems related to thermodynamics, hydrodynamics, and the chemistry of the processes have made automation more complicated. The high turnover in fashion has affected ..

SMOKE ABATEMENT FOR TEXTILE FINISHERS

Fabrics heated to 300 to 400 degrees Fahrenheit in tenter frames, dryers, ovens, and cure boxes produce a blue-gray smoke. Pollution control agencies are increasingly requiring abatement of this smoke. Applicable smoke abatement equipment includes after-burners, scrubbers, condensation filters, and the Beltran electrostatic precipitator. ..
