1.1 INTRODUCTION
In textile sector dyeing is an important process. Dyeing is the steps on which uniform colouring of the cloth is depend. Now a day’s dyeing of the cloth is doing only by deep process. Deep process is very time consuming and difficult process. Uniform dyeing produces fine garments. Dyeing is a method which imparts beauty to the textile by applying various colours and their shades on to a fabric. Dyeing can be done at any stage of the manufacturing of textile- fibre, yarn, fabric or a finished textile product including garments and apparels. The property of colour fastness depends upon two factors- selection of proper dye according to the textile material to be dyed and selection of the method for dyeing the fibre, yarn or fabric. Dyeing is the process in which a dye molecule gets thoroughly dissolved and dispersed in the carrier. It can be in water or some other carrier also, but it must be able to penetrate and colour the textile materials in the process. In the textile dyeing process the dyeing is carried out at different stages like polymer, yarn, fabric and garment or even at the product stage.
Dyeing process is categorized into 3 types i.e. Batch Dyeing Process, Continuous Dyeing process, Semi-Continuous Dyeing process. Batch Dyeing Process is the most popular and common method used for dyeing of textile materials. Batch dyeing is also sometimes referred to as Exhaust dyeing. This is because in this process, the dye gets slowly transferred from a comparatively large volume dye bath to the substrate or material that is to be dyed. The time taken is also longer. The dye is meant to ‘exhaust’ from dye bath to the substrate. In batch processes, textile substrates can be easily dyed at any stage of their assembly into the desired textile product. This includes fibre, yarn, fabric or garment. A Continuous dyeing process typically consists the following. Dye application, dye fixation with heat or chemicals and finally washing. Continuous dyeing has been found to be most suitable for woven fabrics. Mostly continuous dye ranges are designed for dyeing blends of polyester and cotton. The step of padding plays a key role in the operation of continuous dyeing. Sometimes Nylon carpets are also dyed in continuous processes, but the design ranges for them is unlike that for flat fabrics. Warps are also dyed in continuous process. Very good examples of such warp dyeing are long chain warp dyeing and slasher dyeing using indigo. In the process of semi-continuous dyeing that consists of pad-batch, pad-jig, pad-roll the fabric is first impregnated with the dye-liquor in, what is called a padding machine. Then it is subjected to batch wise treatment in a jigger. It could also be stored with a slow rotation for many hours. In the pad-batch this treatment is done at room temperature while in pad- roll it is done at increased temperature by employing a heating chamber. This helps in fixation of the dyes on to the fibre. After this fixation process, the material in full width is thoroughly cleansed and rinsed in continuous washing machines. There is only one point of difference between Continuous and semi-continuous dyeing process is that in semi-continuous dyeing, the dye is applied continuously by padding. The fixation and washing remaining discontinuous. Liquor Ratio in semi-continuous dyeing is not of much importance and is not taken as a parameter. One of the widely used techniques for semi-continuous dyeing process is the Pad Batch Dyeing a schematic diagram is given here for the semi-continuous process.
Colour is applied to fabric by different methods and at different stages of the textile manufacturing process viz. stock dyeing, top dyeing, piece dyeing, Solution pigments or dope dyeing, Garment dyeing, yarn dyeing. Stock dyeing is used to dye fibres. In this process, the staple fibres are packed into a vessel and then dye liquid is forced through them. Although the dye solution is pumped in large quantities, the dye may not penetrate completely into the fibres and some areas may be left without dyeing. However, the following blending and spinning processes mix up the fibres in such a thorough way that it results in an overall even colour. Woolens are usually stock dyed. Top is the combed wool. In this method, the fibre is dyed in the stage just before the appearance of finished yarn. Piece dyeing, in this method, small batches of constructed natural colored fabric are dyed according to the demands for a given colour. It is the process in which the entire roll of the cloth is dyed and then cut as needed or cut pieces of cloth are dyed before the garment is assembled. In this process the cloth is placed in dyeing machine and passed through the dye solution for specified length of time. Once the cloth is dyed it is cut according to your pattern and sewn using the same colour thread. Dye is added to the solution before it is extruded through the spinnerets for making synthetic filaments. Garment dyeing Dye is applied to finished products such as apparels and garment. Stock dyeing is used to dye fibres. In this process, the staple fibres are packed into a vessel and then dye liquid is forced through them. Although the dye solution is pumped in large quantities, the dye may not penetrate completely into the fibres and some areas may be left without dyeing. However, the following blending and spinning processes mix up the fibres in such a thorough way that it results in an overall even colour. When dyeing is done after the fibre has been spun into yarn, it is called yarn dyeing. In this method, the dyestuff penetrates the fibres to the core of the yarn. There are many forms of yarn dyeing- Skein (Hank) Dyeing, Package Dyeing, Warp-beam Dyeing, and Space Dyeing.
1.1 AIM OF THE PROJECT
The aim of this automatic machine is to reduce operating time and also to increase dyeing rate.
1.2 OBJECTIVE OF THE PROJECT
The objectives of present study is to develop a low cost, simple in design an Automatic cloth dyeing machine with conventional source of Energy & which will be economical, user friendly and highly efficient.
1.3 ADVANTAGES OF THE PROJECT
- Construction and operation of winch are very simple.
- The dyeing machines are suitable for types of wet processing operations from desizing to softening.
- The dyeing machine is suitable for practically all types of fabrics, which can withstand creasing in rope form processing.
- The tension exerted on winch is less the material thus dyed is with fuller hand.
- The appearance of the dyed goods is clean and smooth on winch dyeing machines.
1.4 LIMITATIONS OF DYEING MACHINE
- Dyeing operations needs trimming, sewing, and opening out the rope, loading and unloading for individual lots separately.
- Since several lengths of fabric are run over the winch reel into the liquor and sewn end to end, Continuous length processing is not possible in a single batch.
- Fabric is processed in rope form which may lead to crease marks, particularly in heavy, woven, thin and light synthetics.
- Most of the machine work under atmospheric conditions.
1.5 SCOPE OF RESEARCH
To provide Innovative design of a cloth dyeing machine which is very simple even an unskilled labour can operate it. To achieve no drop in temperature so that continuous heating of water should not require.
1.6 PROBLEM STATEMENT
Traditional process of cloth dyeing in commercial stores is very time consuming and also difficult to perform. With this process only one cloth can be coloured in one attempt. As per the observation, time required for a cloth to be coloured is 90 minutes (average). Also the process is completely manual thus dyeing rate is also less. Operating time and dyeing rate are the most important parameters in dyeing process. They are measured as the performance and efficiency of the process. The main achievement with this machine is not only increased dyeing rate but also time required for dyeing is decreasing drastically. Because of its closed system, temperature drop is very slow continuous heating is not required thus energy is saved and two or more clothes can be coloured at a same time. Moreover dipping & stirring are done automatically. Following table shows the entire manual process.
