DEVELOPMENTS IN TEXTILE MACHINERY

Recent trends in textile machinery include reduction of water and chemical use on continuous rope and open -width machines for pretreatments, rapid heating and cooling on batch dyeing machines, a 36-color screen printer, new laminating/coating machines, and laboratory-scale HT/HP and jet dyeing machines. New machinery for pretreatment, dy..

EXPOMATEX 89--DEVELOPING MACHINERY--DYEING, FINISHING, AND PRINTING

Wet finishing machinery was well represented at Expomatex 89 in Barcelona. Major Spanish manufacturers as well as the best known international machinery manufacturers stressed the reduction of cost, energy consumption, raw material, time, and labor in the machinery they exhibited. Emphasis was placed on automation for control and reliable..

ULTRASOUND TO ACCELERATE WET PROCESSING IN DYEING.

The effect of ultrasound on diffusion of CI Direct Red 81 in a cellulose film was examined. The diffusion and permeability coefficients and the time lag were calculated for a control and for 40 and 50 percent ultrasound. Both coefficients increased significantly with ultrasound. Irradiating the film directly or using higher ultrasonic pow..

OPTIMAL COMMERCIAL FORMS OF THE FUTURE.

The history and development of the science of dyes and dyeing is reviewed as part of a general environmental analysis of commercial forms used in European industry. The waste effluent from solid formulations--press cakes, powders, and pastes--tends to be more ecologically disruptive than the effluent produced by liquid dyes. General toxic..

SAVING DYESTUFFS WITH THE OF PROCESS AUTOMATION SYSTEMS.

Through the use of dye liquor consumption analysis, dyers can reduce the quantity of residual liquor. Process monitoring can be used to analyze fabric weight, fabric length, liquor uptake, and liquor consumption. Consumption analysis also enables improved pretreatment and drying control.

SOFTWARE FOR THE DYEHOUSE.

ATYC has used the Microlor series of microprocessors, which were developed for the automatic control of dyeing machines, dye kitchens, and chemical dispensing systems, to develop dyehouse software. The ATYC software is capable of the following: dye recipe preparation, dye lot production planning, and dye machine planning; detailed machine..

DYEING AND FINISHING MACHINES.

Machinery to be exhibited by Thies at the 1991 ITMA is reviewed. The company will feature several dyeing machines, including the Mini-Soft-Midi-Soft machines for laboratory sample dyeing and small lots, the Eco-Soft short liquor dyeing machine for knit and woven fabrics, the Soft-TRD horizontal dyeing machine for synthetic fibers, and the..

RECENT ADVANCES IN DISPERSE DYE DEVELOPMENT AND APLICATIONS.

Standard anthraquinone disperse dyes, which are used for bright red and bright blue shades in the dyeing of polyester blends, are poorly wet-fast, expensive, and--due to the presence of mercury in their manufacture--environmentally hazardous. The formation, structure, and wetfastness properties of several new alternative types of dyes for..

ACRYLIC BLENDS GAINING IN POPULARITY.

Acrylic fibers in blends, particularly acrylic/wool blends, are becoming more popular. Acrylic/wool blends require dyes of different ionic character to ensure high quality of dyefastness. Migrating cationic dyes for the acrylic component are more dependable and permit shorter dyeing cycles. They also provide a wider spectrum of shades and..
