What is jet dyeing machine?
Jet dye machine is the most modern machine used for dyeing of polyester using disperse dye. It is similar to winch dyeing and fabric is processed in continuous loop. The technique is especially useful for delicate polyester fabrics but depending on the machine almost any weight, structure, or fabric type can be used.
What are the steps of dyeing?
What is the Process of dyeing Fabric?
- Singeing and Desizing: They are the first two steps of pre-treatment respectively.
- Sourcing: This is done to remove the impurities over the textile material.
- Bleaching: In this step, the natural color of the raw materials reduced.
Which machine is used for dyeing?
Jigg or jigger dyeing machine is one of the oldest dyeing machines used for cloth dyeing operations. Jigger machine is suitable for dyeing of woven fabrics, up to boiling temperature without any creasing.
What are the 5 methods of fabric dyeing?
Methods of Dyeing
- 1) Bale Dyeing: This is a low cost method to dye cotton cloth.
- 2) Batik Dyeing: This is one of the oldest forms known to man.
- 3) Beam Dyeing: In this method the warp is dyed prior to weaving.
- 4) Burl or speck Dyeing:
- 5) Chain Dyeing:
- 6) Cross Dyeing:
- 7) Jig Dyeing:
- 8) Piece Dyeing:
How many types of dyeing machines are there?
Types of dyeing machines according to textile material:
Fiber dyeing machine. Yarn dyeing machine. Fabric dyeing machine. Garment dyeing machine.
What is the purpose of Venturi used in jet dyeing?
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.
What is dye method?
A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Generally, a dyeing process involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre).
What is the purpose of dyeing?
The primary objective of dyeing is to apply uniform color to the substrate (fiber, yarn, or fabric) with required color fastness. Tie-dye and printing are the methods where the color is applied in a localized manner.
How does a dyeing machine work?
In jet dyeing machines a strong jet of dye liquor is pumped out from an annular ring through which a rope of fabric passes in a tube called a venturi. This venturi tube has a constriction, so the force of the dye liquor passing through it pulls the fabric with it from the front to the back of the machine.
How do you calculate dye capacity?
So, the capacity of a package dyeing machine can be estimated in below formula. Average Production Capacity = (Batch Loading Capacity * Machine Efficiency * 24 / 10) kg/day. If an 85% efficient machine has capability of dyeing 500 kg yarn in each batch, average production will be 1020 kg/day.
What are the four stages of dyeing?
1. Stages of Dyeing
- Dyeing at Fibre Stage. The process of dyeing at fibre stage is called as fibre dyeing.
- Dyeing at Yarn Stage. The process of dyeing at yarn stage is called as yarn dyeing.
- Dyeing at Fabric Stage. The process of dyeing woven or knitted fabric is called as piece dyeing.
- Dyeing at Product Stage.
Which is continuous dyeing machines?
Continuous dyeing Continuous dyeing machine:- Continuous dyeing machine is the such a types of dyeing machine in which the fabric is treated continuously. o Types of continuous dyeing machine 1) Pad thermosol dyeing machine 2) Pad steam dyeing machine 3) Pad dry chemical pad steam dyeing machine Pad Thermosol …
What is soft flow machine?
In the soft flow dyeing machine water is used for keeping the fabric in circulation. The conception difference of this equipment from a conventional jets that operates with a hydraulic system is that the fabric rope is kept circulating during the whole processing cycle (right from loading to unloading).
What is dye and its types?
Different Types of Dyes with Chemical Structure
| Name of Dyes | Application |
|---|---|
| Basic dye | Jute, Acrylic |
| Reactive dye | Cotton, Wool, Silk, Viscose, Nylon |
| Sulfur dye | Cotton, Viscose |
| Mordant dye | Cotton, Wool, Silk |
What are the 3 types of dyes?
Synthetic Dye. All the dyes that are derived from organic and inorganic chemical compounds are synthetic dyes.
What is soft flow dyeing machine?
What is the formula of dye?
Required Dye = (Shade percentage (%) x Weight of the fabric in gram (gm)/percentage (%) of Stock solution. Calculation of dyestuff will be, for, Rema Blue RR = (1.12 2x 5)/1=5.61 g/l.
What is ML ratio in dyeing?
1.8 Liquor ratio in dyeing
Liquor ratio may be defined as volume of liquor to be taken in dyebath in proportion to weight of textile. If a piece of textile weighing ‘y’ g is to be dyed at a liquor ratio of 1:5, volume of water would be ‘5y’ ml.
How many types of dye are there?
There are three categories: Cellulose fiber dye. Protein fibers dye. Synthetic fibers dye.
What is the classification of dyes?
Dyes may also be classified by their method of application to the substrate. Such a classification would include direct dyes, reactive dyes, vat dyes, disperse dyes, azoic dyes, and several more types.
How do you calculate percentage of dye?
What is E control dyeing?
Econtrol dyeing process was introduced by Dystar and Monforts in ITMA in 1995 to provide the textile dyer with a dyeing system that would produce a simple, rapid, and economical, continuous dyeing method for cellulosic fibers with minimal chemical usage.
What is soft dye?
In soft flow dyeing machines the fabric is transported by a stream of dye liquor. However, the transport is assisted by a driven lifter reel. 3. These machines use a jet having lower velocity that that used on conventional jet dyeing machines.
What is the basic dye?
1. Basic dyes are water-soluble cationic dyes that are mainly applied to acrylic fibers, but find some use for wool and silk. Usually acetic acid is added to the dye bath to help the uptake of the dye onto the fiber. Basic dyes are also used in the coloration of paper.
What is dye used for?
Dyes are used primarily to impart color to textiles, leather, paints, photographs, cosmetic and pharmaceutical products, biological stains, and food. Many natural dyes have been largely replaced by synthetic dyes that were developed at the end of the nineteenth century.
