Innodye & Innovat machines
The Innodye® machine features translational motion of the treatment bath, utilizing a mobile basket that traverses the bottom of the machine, thereby eliminating the need for a plaiter.

Additional features include reduced bath foaming, improved homogeneity of the bath, increased fabric/liquor interaction to enhance levelness and washing, and reduced tangling.

The Innovat® is based on the Innodye® and offers an oxygen-free atmosphere for the running of vat dyes. Utilizing vacuum technology and continuous rinsing, the machine promotes problem-free vat dyeings.

With over 40 years of specific experience in the textile sector, Brazzoli is popular among the leading firms in Pakistan as the manufacturer of dyeing machines, with high technological content for the treatment of fabrics in rope form.

RotoSwing Tumble & Relax Dryer

The RotoSwing is ideal for tumbler-resistant goods with residual shrinkage values that usually lie between 0 and less than 5 %, depending on the fabric construction and the respective pre-treatment. It is now possible to wash and dry knitwear in household washing machines and electric dryers, to maintain their dimensional stability and avoid shrinkage of the garments.

RT Thermosol Unit of the Third Generation
RT stands for Rational Thermosoling and the fabric is usually supplied from a pile or a batch. The intake is designed such that a continuous change of batches is possible without having to stop the machine. For dyestuff application padders of renowned suppliers are used. A moisture measuring system constantly measures the liquor application across the width (left, right and center) and together with the computer control system of the padder supplier controls the liquor application. This ensures uniform dyeing and good reproducibility.

· Extremely short heating-up periods of about 1 to 1.5 seconds owing to the perforated drum principle.

· This results in greatly reduced heat setting periods for the dyestuff of only about 30 seconds for medium dye shades and about 40 seconds for dark shades.

· High temperature uniformity across the entire working width: only +/- 1.5°C for a temperature of 230°C.

Advantages of the RT Unit:

The HT-SteamSet
In the knitwear industry more and more Spandex fibers (like e.g. Lycra) is used to achieve higher elasticity of certain goods. The use of such elasthan fibers causes the fabric edge to roll up even more than pure cotton after cutting it open. In addition there is the negative effect of the elasthan thread withdrawing from the cut edge both after cutting open the tube and when cutting the fabric before making-up so that the fabric near the cutting edge cannot be utilized. Preliminary heatsetting of the raw material prevents the elasthan thread from withdrawing and offers additional advantages for finishing, namely:

· better evenness during dyeing
· reduced pilling tendency during dyeing
· reduced dyestuff consumption
· reduced crease formation during bleaching and dyeing
· the "twisting effect" of elasthan-containing fabric due to imminent curling is eliminated
· no markings of spreaders.

WIDE RANGE OF Dyeing Machines

Luft-Roto Plus
Thies' Luft-Roto Plus is considered as an environment friendly and cost-effective rapid-dyeing machine.
