Jet Dyeing Machine - Woven Dyeing

The main difference between jet andoverflows machines is that in jet machines the fabric gets transported by a bath thatflows at high speed through the nozzle, while in Overflow Dyeing M

Jet Dyeing Machine

It was found that in using Winch machines, there were some inherent problems So

the Jet dyeing machines when they came up in the 1970's, were specifically designed

to overcome those shortcomings

In the Jet dyeing machine the reel is completely eliminated A closed tubular system exists where the fabric is placed For transporting the fabric through the tube a jet of dye liquor is supplied through a venturi The Jet creates turbulence This helps in dye penetration along with preventing the fabric from touching the walls of the tube As the fabric is often exposed to comparatively higher concentrations of liquor within the transport tube, so little dye bath is needed in the bottom of the vessel This is just enough for the smooth movement from rear to front Aqueous jet dyeing machines generally employs a driven winch reel along with a jet nozzle

The following diagram explains the functioning of a Jet dyeing machine:

Types of Jet Dyeing Machine

In deciding the type of dyeing machine the following features are generally taken intoconsideration for differentiating They are the following Shape of the area where thefabric is stored i.e long shaped machine or J-box compact machine Type of thenozzle along with its specific positioning i.e above or below the bath level.Depending more or less in this criteria for differentiation following types of JetMachines can be said to be as developments of the conventional jet dyeing machine

B. Soft-flow Dyeing Machine

C. Airflow Dyeing Machine

Advantages of Jet Dyeing Machine

The Jet Dyeing Machine offers the following striking advantages that makes them suitable for fabrics like polyesters

• Low consumption of water

• Short dyeing time

• Can be easily operated at high temperatures and pressure

Comparatively low liquor ratios, typically ranges between 1:4 and 1:20

• Fabrics are handled carefully and gently

A. Overflow Dyeing Machine

Overflows Dyeing Machines are designed for use in delicate knitted and wovenfabrics that are made up of natural as well as synthetic fibers They are alsoextensively used in the production of carpets The main difference between jet andoverflows machines is that in jet machines the fabric gets transported by a bath thatflows at high speed through the nozzle, while in Overflow Dyeing Machine it is thegravitational force of the liquor overflow that is responsible for fabric transportation

Functioning of a Overflow Dyeing Machine

A typical Overflow Dyeing Machine works like this A winch that is not motor drivenusually is located in the top side of the machine where the fabric is hanged A longerlength of textile is made to hang from the exit side of the winch as compared to theinlet side By applying the force of gravitation the longer length of textile is pulleddownward more strongly than the shorter one Consequently the fabric is soaked inthe bath without any sort of tension The following diagram well illustrates theworking process

Advantages of Overflow Dyeing Machine

• No evaporative losses- As the dyeing vessel is closed, there is no evaporative

losses stemming from the dye bath Further, depending on the situation thetemperature may be raised to more than 1000oC

• No build up of steam condensate in the dye bath- The latest technology

implies that the dye bath gets heated by a heat transducer which is steamdriven This technology apart from being very efficient ensures that there is nobuild up of steam condensate in the dye bath

• Low liquor ratios- Dyeing is conducted at relatively low liquor ratios, e.g.

10:1 and may be lesser resulting in substantial savings in water and energy

• Excellent dye liquor contact- Excellent dye liquor contact with the fabric rope

results in better and more improved level dyeing

• Computer control- The machines are operated by computer and hence,

operator error is eliminated

B. Soft-flow Dyeing Machine

In the soft flow dyeing machine water is used for keeping the fabric in circulation.The conceptional difference of this equipment from a conventional jets that operateswith a hydraulic system is that the fabric rope is kept circulating during the wholeprocessing cycle (right from loading to unloading) There is no stopping of liquor or

The principle working behind the technique is very unique There is a system for freshwater to enter the vessel via a heat exchanger to a special interchange zone At thesame time the contaminated liquor is allowed channel out through a drain without anysort of contact with the fabric or for that matter the new bath in the machine

Key Features of Soft flow Dyeing Machine

• Significant savings in processing time

• Savings in water that is around 50%

• Excellent separation of different streams results in optimum heat recovery and

a distinct possibility of further use or a dedicated treatment

C Airflow Dyeing Machine

This is another development of the very popular jet dyeing machines The main difference between the Air Flow Machine and Jet Dyeing machine is that the airflow machine utilizes an air jet instead of the water jet for keeping the fabric in circulation.Typically the fabric is allowed to pass into the storage area that has a very small amount of free liquor This results in a reduction in consumption of water, energy andchemicals

The figure below shows how in an Airflow Machine the bath level is always under the level of the processed textile Here the fabric does not remain in touch with the liquor (the bath used is below the basket that holds the fabric in circulation) This invariably means that the bath conditions can be altered without having any impact

on the process phase of the substrate

Advantages of Airflow Machine

• Completely Separated circuit for liquor circulation without getting in touch with the textile

• Bath less Dyeing operation

• Rinsing process offers all the added benefits of continuous processing as it is

no longer a batch operation

• Extremely low liquor ratio

• Virtually nonstop process

• Comparatively lesser energy requirement due to faster heating/cooling and optimum heat recovery from the hot exhausted dye liquors

• Reduction in consumption of the chemicals (e.g salt) dosage of which is based

on the amount of dye bath

• Lesser water consumption savings up to 50% from the conventional Jet dyeing machines

• Sensitivity towards ecology

• Economical operation

• More safety while dyeing

The New L-shape Airflow

However, the Airflow dyeing machine had one disadvantage: dyeing of extremely delicate fabrics didn't give a perfect result Current and future trends pointing toward more and more lightweight fabrics with high contents of elastane in finest yarn counts and gauges prompted the next stage of Airflow machinery design

To meet the required voluminous hand as well as top-grade quality standards, the world's first long-tube Airflow machine, the Airflow Lotus 200, was developed The new dyeing machine incorporates the latest advances in Then's Airflow technology and operates according to the original aerodynamic principle The dye liquor passes the self-cleaning filter and is then evenly applied and finely distributed as a mist with the aid of the blower, assuring outstanding penetration, according to Then

Schematic drawing of the Airflow® technology: Air is the key element, and is said to be the ideal

medium to transport piece goods in dyeing machines.
