MASTER

in Denim Dyeing 

MASTER, since more than 40 years, designs and manufactures only dyeing machinery for yarn, branch in which boasts an outstanding experience and several machines and patented novelties.

It made research, experimentation and anticipation of new technologies its strong points.

It is world leader in the continuous dyeing, with indigo and other dyestuffs, of denim fabrics warps manufacture.

It is the machine with maximum operative flexibility for the slasher continuous dyeing, with indigo and other dyestuffs, of denim fabric warps.

It is arranged for all the pre and post treatments and for dyeings of yarn's warps, both ring spun or open end, even very light, of cotton, new fibres, blends and elastic too, in a very wide range of blue, black and different colours, in line with the fashion's trend.

Its special vats with optimized shape and dipping times, equipped with the ingenious and efficient double overflow circulation system, the effective computerized monitoring and dosing automatic systems among which the hydrosulphite ponderal one too, the squeezing units with equipressure rollers, the exclusive oxidation enhancing devices RAPIDSKY® and the intensive washing units ECOWASH® made it the much evolved and more technologically advanced and, at the same time, easy and reliable machine.

It performs its maximum usage flexibility by the special TWINFLOW® (Pat.) vats, which can be used, beside at full capacity with indigo, with reduced bath's volume too, fed by a suitable independent circuit, for the "colourdenim" dyeing with sulphur, indanthrene, reactive dyestuffs, etc.

Its peculiar constructional characteristics, together with the continuous evolution and constant updating, allow high quality, repeatable, economic and ecological dyeings.

It is the machine used by the top class worldwide denim manufactures.

It is a new machine for the rope continuous dyeing, with indigo and other dyestuffs, of denim fabric warps, in which, to the tradition, have been added the modernity, the reliability and the completeness.

Furthermore, it born already technologically advanced thanks also to the cooperation with the high ranking worldwide denim manufacturers.

It is arranged for all the pre and post treatments and for dyeings of warps rope, both ring spun or open end, even very light, of cotton, new fibres, blends, in a very wide range of blue, black and different colours, in line with the fashion's trend.

Three sets of gangways, on the side and crossing, connected by suitable ladders, make the whole yarn's path accessible and checkable, where everything is designed at human size so to make any intervention easy, simple and safe; therefore it is practical, reliable and ergonomic.Furthermore the basic version, equipped with the dryers and coiler is set for possible future upgrading with steamers, etc.

It is equipped with the more reliable computerized dosing and monitoring automatic systems, the hydrosulphite dosing and dissolving automatic system, as well as with the tank for the collecting of the overflow indigo's bath and with a complete colour kitchen; the whole at guarantee of high quality level dyeings and consistency.

It is a new machine for the slasher continuous dyeing, with indigo and other dyestuffs, of denim fabric warps, which, instead of the normal N. 6-8 dyeing vats, uses the genial ecological and economical technology of two or more Genius® (Pat.).

Genius® (Pat.) is an integrated dyeing module, consisting in a special combination of a special dyeing vat, with a group for the diffusion of leuco in yarn by heat activation and long permanence in inert environment. This allow, among other, to operate also with high concentration, with low level and at high temperature too, new proceedings which add to the already known, with possible different dyeing results.

Genius® (Pat.) allows a new indigo dyeing technology, the more advanced, ecological and economical, which eliminate much of the typical problems of the traditional dyeing technology.

Genius® (Pat.) is moreover particularly fitted to the use of sulphur, indanthrene, reactive, etc. dyestuffs.

Genius® (Pat.) is the arrival point of the whole MASTER research, the starting point to the future.

Genius® (Pat.) compared to the traditional slasher machines, has the following advantages:

  • dyeing process independent from external variables
  • higher dyeing yield
  • better diffusion and fixation of indigo dyestuff to the fibre
  • drastic reduction in the sodium hydrosulphite and caustic soda consumption
  • dyeing vats number reduction
  • yarn wastage reduction at lot change
  • operative flexibility
  • process application, with sure lower environmental impact, for the organic cotton (biologic) dyeing -
  • nitrogen reduced consumption (compared to other systems)
  • intervention and maintenance easiness
  • environment respect and ecology

Genius® (Pat.) brings innovation in the dyeing processes and in the high quality textile and, moreover for the notable savings with considerable production costs reductions.
