INTRODUCTION/IMPORTANCE Package dyeing machines are the most widely used

now a days for dyeing of almost all types of yarns , due to automatic, economical and accurate dyeing results.

Term package dyeing usually denotes for dyeing of any type yarn wound on the compressible dye spring/perforated solid dyeing tubes or cones.

Yarn dyeing in package form is done at high temperature and under high pressure, with the package mounted on the hollow spindles these spindle are fixed on the dyeing carrier

The dyeing liquor is forced through the package in two way pattern (in/out-out/in)

All operation from pre-treatment to finishing can be performed in the same machine, without taking out the material out of the machine

RBNO HORIZONTAL DYEING MACHINE

RBNO horizontal dyeing machines operate with material fully immersed in dyeing liquor.

Yarn packages, tops or bumps are loaded on dyeing carriers with rectangular base, fitted with vertical spindles.

Liquor flow through the material is BIDIRECTIONAL

Dyestuffs are injected into the highest turbulence point of liquor circulation pump

Yarns are dyed in on Cheese Package Requires a liquor ratio of 3.5:1

ENVIRONMENTAL ASPECTS1. The air pad operates as a double chamber to

reduce heat emissions in the dyehouse.2. No emission of chemical vapours.3. Low water, steam, power consumption and

very limited pollution of effluents

RBNV VERTICAL DYEING MACHINE

RBNV dyeing machines operate with material fully immersed in dyeing liquor.

Liquor flow through the material is bidirectional

The entire liquor volume participates to the dyeing process and dyes exhaustion rate it is perfectly homogeneous.

RBNV is energy efficient and environment- friendly due to substantial savings in cooling water,steam and electric power

Liquor ratio is adjustable to optimize processing condition, by means of automatic liquor level controls

RBNV FEATURES: Nominal loading capacities from 5 to 1500

kgs. Construction entirely in AISI 316 stainless

steel. Water protected motors and electrical

equipment Interchangeable Dyeing Carriers Flexibility in loading rate and textiles A. Half load

B. Reduced load

C. Full load

ECO BLOCK YARN DYEING

Eco-bloc can be used to process material in many forms including yarn packages,muffs, warp beams, loose stock,tops, ribbons and tapes made of natural, man-made fibres and their blends.

type of material effective liquor ratios from 1:3,5 to 1:8 can be readily achieved.

All parts of the eco-bloc coming into contact with the liquor are manufactured from stainless steel as well as the kier base plate, pump circulation system and flanged connections

The Eco blocks are available in both Vertical (eco-bloc X) and horizontal execution (eco-bloc HV)

Techical details:1. Liquor return to the 100% Stock Tank re-use

of bleach , rinsing or dye liquor 2. Analogue dosing programmable automated

dosing of dyes and auxiliaries using time and curve profiles (also applicable under HT contidions)

3. Operating temperature max. 140c at 5 bar pressure

4. Batch sizes from 1 to 10000 kg5. Option of the vertical or horizontal dyeing

machines 6. Automated process control using industrial

PC

HTHP PACKAGE DYEING MACHINE

Suitable for processing natural and synthetic fibers and their blends: 100% cotton, poly/cotton, polyester, poly/wool, acrylic, nylon, ramie/cotton, woolen

Versatile enough to process a large variety of yarns make-ups

Low ratio can save the dyestuff, auxiliaries and energy

Rapid rinsing system can reduce rinsing time and water consumption.

Advanced dyeing computer for auto control of water supply, drain, heating, temperature preservation, cooling and rinsing.

Technical Data：The standard size of the package is Ø165*165 ㎜ of 1kg.Designed working pressure: 0.45Mpa Max. working pressure: 0.4Mpa Designed working temperature: 140°C Max. working temperature: 135°C Max. heating rate: Approx. 30 minutes from 20°C ～ 130°C; Cooling rate: Approx. 20 minutes form 130°C～ 80°C.

ALLWIN HIGH TEMPERATURE PACKAGE DYEING MACHINE

Type of YarnsYarn wound in all kinds of dye tubes,

Loose fibre such as cotton, wool, artificial silk etc.

Muffs, tops, tapes, etc. Capacity

From 28~9130 kg/batch  Applications

For the pre-treatment, dyeing and after treatment of packages, bobbins, loose fibre, hank yarn, beams, muffs, tops, tapes, etc.

Designed for the process of yarns on cones, tubes, or in hank form or beam

Requires low liquor ratio ILC Intelligent Leveling Control function  AIR+ and high temperature drain function Water consumption is as low as 34 L/kg for

medium to dark shade

HTHP HORIZONTAL TABULAR DYEING MACHINES

Texfab has designed & developed economical & eco friendly Horizontal tubular type dyeing machine

Having capacities from 20 kgs to 320kgs per batch ( up to 16 tubes)

These machines do not require overhead hoist or working flatform. Hence installation cost is low and machines can be installed on mezzanine of higher floors also

Application : The machine is suitable for dyeing all types of

yarn in package form. It is also suitable for dyeing zippes tapes, small width fabrics & warp beams

Salient features Works on very low liquor ratio of 1:3.5 upwards

depending on nature of yarn & loading factor Variable loading possible from 50% upwards of

the rated capacity without using dummies. Works on airpad dyeing system, resulting in

saving cooling water, heat & electrical energy. Opening closing and locking/unlocking is done,

simultaneously and automatically by electro pneumatic devices with complete safety.

Machines working on gas (CNG) with burner fitted ( without the need of steam or boiler)

Design ensures complete drain of liquor from the machine every time. Thus, preventing accumulation of dye deposits inside the machine and contamination.
