ITMA 1991 -- DYEING AND FINISHING MACHINERY DEVELOPMENTS

New machinery and machine designs in the dyeing and finishing sectors were exhibited at ITMA 1991. In the chemical pretreatment area, a number of novel wet pick-up applicators were shown. In yarn dyeing, the major interests were in compact, modular, low liquor machines and the use of robots for package loading and unloading. In fabric dye..

KINETICS OF DYEING POLYAMIDE WITH GRYFALANY DYES.

Spestrophotometry was used to study the kinetic sorption of Grtfalany dyes that had been applied to nylon. Dyeing half-time, normal concentration,and apparent diffusion coefficient were determined. The Gryfalany dyes were found to have short exhaustion time, good affinity, and similiar diffusivity. The values of each parameter depend on t..

HISTORICAL PROGRESS FROM WINCH BECK TO MODERN PIECE DYEING. PART 1. DEVELOPMENTS LEADING TO THE MOERN ROPE DYEING MACHINE.

The introduction of new fibers and fabrics have had an important infullence on the development of both wich beck and jet dyeing machines. The jet dyeing machine, first introduced during the 1960s,has evolved from models that use the jet for fabric transport to those that use the overflow liquor for fabric transport. A recent machine, the ..

FURTHER DEVELOPED OVERFLOW DYEING MACHINE FOR A WIDE RANGE OF GOODS.

Flainox's Uni-Flow ATP is an overflow dyeing machine for dyeing, scouring, and bleaching a wide range of fabrics. The machine can handle woven and weft or wrap knit fabrics in natural and manmade fibers and blends. Fabric weights ranging from 80 to 800 grams per running meter can be processed. The redesign of this unit focused on the over..

NEW TURBO - SYSTEM HT OVERFLOW MACHINE.

Brazzoli's Turboflow HT is an overflow dyeing machine that processes woven and knit goods in polyester/cotton blends, the entire ranges of manmade fiber, and microfibers. Production speeds as high as 400 meters per minute can be achieved due to the combined effort of the overflow system and a special liquor accelerator. Dyes and auxiliari..
