Preface
Training in business organization infuses among students a sense of critical analysis of the real managerial situation to which they are exposed. My institutions has given me opportunity through training to be aware of and cope with fast rate changing technology, management policies, quality and productivity etc. This is a bold attempt to bridge the gap between the ‘world of work’ and ‘studies imparted in the institutions’
This training enables me to apply theoretical knowledge to practical situations, appreciate the sense of responsibility, importance of discipline, punctuality and the psychology of worker and their habits which make me more professional and near to the world of technology and team work. Industrial training brings out better citizens, better technocrats and better diplomats out of me.
I was lucky to get an opportunity to work in one of the top limited sector industries, i.e. PRATIBHA SYNTEX LTD. The purpose of this training was to gain knowledge about the industry, how it works and also to see the environment of the industry. I joined the training not only for these purpose, but also to learn something about operation of the machines and construction of spinning machines.
I have worked in the concern for 6 weeks and prepared my Industrial training report. Under the guidance of training office, I analyzed various aspects of production. This has helped me in boosting up my confidence and determination, which will help me to face any situation in the years to come.
This report is written account of what I learnt and experienced during this period. I wish, those going through it will not only find it readable but will also find useful information for future reference.

The mixing is done according to a matrix.
5.2. MIXING
OBECTS:
1. TO HAVE A UNIFORM DISTRIBUTION OF DIFFERENT TYPES OF COTTON
2. TO REDUCE THE COST OF RAW MATERIAL USED3. TO APPLY SPIN FINISH & TINT ( IF REQUIRED ) ON MATERIAL TO
IMPROVE PROCESS PERFORMANCE & TO SEGREGATE THE MATERIAL FROM OTHER KINDS.
4. Removing waste and contamination by sorting.
IN ORDER TO HAVE BEST RESULT, FOLLOWING POINTS SHOULD BE UNDER CONSIDERATION
1. FIBRES MUST HAVE SAME ORIGIN 2. PRICE, COLOUR & GRADE OF COTTON IS ALSO KEPT IN MIND WHILE LAYING MIXING 3. QUALITY OF MIXING TO BE LAID 4. SOFT WASTE SHOULD BE ADDED AS PER REQUIREMENT
Types of mixing-1.Hand mixing2.Bin mixing3.Stack mixing The lots for the mixing should have somewhat identical properties. Very coarse and very fine or very short and long cotton are never mixed.
19

LENGTH-2.0 FEETBREADTH-1.5 FEETHEIGHT-4.5 FEET
CONTAMINATIONS REMOVED DURING SORTING PROCESS:
1. Plastic dori2. Paper3. Cloth4. Polythene5. Wires6. Coconut material7. Feather8. Coloured thread9. Wood10. Leather11. Hair12. Sutli13. Yellow cotton
PRECAUTION WHILE LAYING MIXING:
1. Material should not spread out of yellow line marked on floor. 2. The top layer of mixing should be in same level. 3. Waste should be added uniformly. 4. Bales should not fall after opening them. 5. House keeping should be proper.
BLOW ROOMOBJECT:-The object of blow room is opening and cleaning of cotton.It consist of the following sequence of the machines for the attainment of this object.
1.SIX CHAMBER BLENDER-There are six chamber filled with cotton.Here blending of cotton is to be done by six beater.2.THREE ROLLER CLEANER-There are three rollers having different spikes.The function of three roller cleaner is to clean the cotton.3.HEAVY PARTICLE SEPERATOR-The function of heavy particle separator is to remove the heavy particle by the principle of centrifugal force by circulating the cotton.
20
4.PINNED OPENER AND CLEANER-The spikes of roller is pin-like which open the cotton and so impurities are removed,so clean tha cotton.5.FINE OPENER AND CLEANER-Here fine impurities are removed from cotton. Spikes of rollers are very fine.
6. CONTAMINATION SORTING MACHINE-There are two separators -
1. Vetal-It works on the camera vision. It has 24 sensors, which sense the contamination,And is recorded by the camera and is ejected by the air pressure.2. Loptex-Total 56 sensor sense the contamination and are ejected by the air pressure.

CARDINGCarding is the heart of spinning.The objects of carding are:-
1. Individualization of fibre2. Disentanglement of neps3. Sliver formation 4. Cleaning action
The chute feed system feeds the machine. Types of card:-1. Tandem card (16 in no.)REAKER
The main carding action takes place between cylinder and flat. To control the feed autoleveller are installed in the machine.
DUO OR TANDEM CARDING
As the name implies, tandem cards consists of two individual cards joined together to make up a unit, in which the doffer of the first card feeds fibre material to the taker-in of the second card. Double carding of the raw cotton has a positive effect on quality and on blending. However, these advantageare purchased at the cost of expense in hardware and maintenance, and additional space is required.Modern cards of the latest generation give the same or nearly the same quality. Tandem cards come into consideration.

PRODUCTION/ SHIFT- 4Ton
So the fabric initially in the roll form goes through the following path before it is made into a
finished usable material.
Pratibha Syntex Lmt. has its own Knitting plant. So it has its own production of Knitted fabric as
per sales order which is issued from the buyers. The main advantage of this is that it receives
pre-inspected fabric that’s why inspection process is not being much concentrated but still there
is random inspection takes place during opening & stitching process.
Various activities have been done here as follows:
First of all, the sales order issued by Buyers is received. Production of fabric is as per
required sales order quantity, construction & design.
Then this fabric is dispatch to Cutting Department as per sales order & roll number
specifications.
Challan number/date entry at Cutting department.

B. BLEACHING DEPARTMENT
The grey fabric consists of various kinds of impurities like vegetable matter, waxes etc. In this section all of these impurities are removed and whiteness in fabric is imparted.In this department two main steps are carried out:
35
Pre-treatment
Bleaching
i) Pre-treatment
a) Scouring: Scouring is the first process carried out with or without chemicals, at room temperature or at suitable higher temperatures with the addition of suitable wetting agents, alkali and so on. Scouring removes all the waxes, pectins and makes the textile material hydrophilic or water absorbent.
b) Bleaching: The next process of decolorization of greige material in to a suitable material for next processing is called bleaching. Bleaching of textiles can be classified in to oxidative bleaching and reductive bleaching.
Oxidative bleaching
Generally oxidative bleachings are carried out using sodium hypochlorite, sodium chlorite or hydrogen peroxide. Natural fibres like cotton, ramie, jute, wool, bamboo are all generally bleached with oxidative methods.
Reductive bleaching
Reductive method of bleaching is done with Sodium hydrosulphite, a powerful reducing agent. Fibres like Polyamide, Polyacrylics and Polyacetates can be bleached using reductive bleaching technology.
In this step scouring and bleaching are carried out in a single machine.
The Benninger continuous pretreatment concepts comprise continuous desizing and bleaching in one cycle with just one steaming process. In one step grey cloth is turned to dye ready fabric.
This process is fast, economical and of immaculate quality. Due to this optimized one-level process the operational costs are lowered by approximately thirty percent, and the impact on the environment is significantly lower.

The ERBATECH machine is mainly divided into 5 main parts
1. Parcowash Zone -1
In this initial step the Dust,impurities etc are removed using hot water and steam. All the processes are carried out in a chamber known as parcowash-1. There are 3 chemicals used for pre-washing.
Name of chemical Working
Sirrix N Sequesting agent2UDI Water hardness controllerMRZ Wetting AgentTemp. 70oc
2. Impregnating:
In the main Bleaching zone the fabric is impregnated with chemicals for subsequent troublefree
37
steaming process. The design ensures that a high liquor exchange is achieved. The chemicals are distributed immediately at the right place in the fabric. The chemicals added are as follows:
Chemical used Working of chemical
H2O2 Bleaching agent
Sifa M Reaction Stablizer
MRZ Wetting agent
Caustic soda Swelling,cleaning agent
Sirrix N Sequesting agent
Temp. 97 oc
3. Steaming:
In the steamer the chemicals react with the fibres themselves and the accompanying substances. The combination steamer with tight strand cloth runsand plaiting on a roller bed permits reaction times of 1 to 60 minutes. An automatic steam conditioning and regulating station guarantees constant conditionsand an air free atmosphere. In this machine steaming time was 13-14 minutes. The steam is used in the following conditions:
Temperature of steam mix: 102oc4. Washing:
The chemicals which have been made soluble by steaming, are washed out. The high washing effect of this machine is achieved through exact liquor segregation andcounter-flow guidance. It has been designed for especially low power and water consumption. Final washing is done in 4 subsequent chambers.

C. DYEING DEPARTMENT
Dyeing is the process of imparting colors to a textile material through a dye (color). Dyes are obtained from flowers, nuts, berries and other forms of vegetables and plants as well as from animal and mineral sources. These are known as natural dyes.
The other class of dyes is known as synthetic dyes. These are based on a particular type of chemical composition. Some of these dyes are- Acid (Anionic) dyes, Basic (Cationic) dyes, Neutral- Pre metalized dyes, sulfur dyes, vat dyes, reactive dyes, pigment dyes etc.
Colour is applied to fabric by different methods of dyeing for different types of fiber and at different stages of the textile production process. These methods include Direct dyeing; Stock dyeing; Top dyeing; Yarn dyeing; Piece dyeing; Solution pigmenting or dope dyeing; Garment dyeing etc. Of these Direct dyeing and Yarn Dyeing methods are the most
39
popular ones.
Dyeing is defined as the application of dye to fibers (according to their affinity) to have desired colour. Every natural or synthetic fiber varies in affinity or capacity to take the dyestuffs. Dyeing is done at fabric stage. Main types of fabrics those are dyed are:
1) 100% cotton fabric2) L/C blend
(A)DARK SHADE DYEING In dark shade dyeing of cotton cloth we use Reactive dyes are used. And the machine used is Cold pad batch and soaper.

Process of Cold Pad Batch is as follows:
Fabric is passed through the cold rollers to keep the temperature of the fabric even so that the classes of dyes used are better reactive .
Then fabric is passed through the Padding mangle where the colour padding takes place. The color recipe used here is 1 part Sodium Silicate as fixing agent and 4 parts of colour. speed here is 44Mts./min.
The fabric is then sent for rotation of 8 hours. The time allotted is the dwelling time and within this time the colour fixing happens and the fabric absorbs the dye equally.
And at the end fabric is sent on the washing range where the fabric is washed and dried on the drying range.
Flow of fabric in Cold Pad Batch Machine
ERBATECH SOAPER
The washing range primarily is used to wipe out the superficial colour absorbed by the fabric and then send to the finishing department.
The process of Washing Range is as follows: The dyed fabric is washed with the counter flow of water at 98 degree of temperature. Then the fabric is washed in soap solution in two chambers. Then again the fabric is passed through water. And finally the fabric is passed through acetic acid where it is neutralized and then the fabric
is dried as the acetic acid is volatile in nature thus it does not require any further washing. After the fabric is passed through the drying range it is drying in Pin Dryer and sent to
finishing department.Excellent results have been obtained with the pad batch (cold) system utilizing high reactivity dyes. Dyers have experienced many benefits,
41
Some of which are listed ahead:1. Reduction in waste loads in effluent 2. Low capital outlay. 3. Low energy requirements. 4. High production speed 5. Less labour requirement. 6. High colour yield 7. Outstanding productivity. 8. Excellent dye penetration and levelling characteristics. 9. Rapid fixation10. Substantial overall cost savings (dyes, chemicals, labour, water. The fabric undergoes less turbulence during the cold pad batch dyeing process, and therefore retains a smooth, uniformly coloured appearance with added luster and a soft touch and drape. It is also brighter in shade, has superior wet fastness properties, and has a better look and feel.
D. FINISHING DEPARTMENT
Finishing is the final series of operations that produces finished textile fabric from greige goods. Finishing operations are predominantly wet operations requiring large amounts of thermal energy for water heating and drying.
Finish is applied on the textile material by different chemical and mechanical means. The finish
to be applied on textile material depends upon the end use of the fabric.
OBJECTIVES
To improve the appearance of fabric
To increase the whiteness
To provide anti-shrink properties
To provide soft feel to the fabric
To increase the width of the fabric
To improve dimensional stability.

Different parts of stenter :Brushes after pinning: Since the pinning shoes only bring the fabric on to the tips of the pins, the function of the subsequent brushes to press the f/c fully on to the pins. The brushes are mounted on a pivoting lever, which after releasing a locking handle, can be moved to the non operational position or working.
Vertical feed roller: The feed roller is located right ahead of the pinning or clipping positions. It can be moved to various positions by means of pneumatic cylinders.Steam spray cleaning unit clips/pins: Some time finish chemicals such as softener etc. cling or stick to the pin over a period of time softener, residue of glue & condensates can build up on the needle bars & clip tables the steam spray cleaning unit for pin chains or combination chains can be used.Brushes for needles: Over a period of time softener residue of glue & condensates can build up on the needle bars &clip tables, impairing the function of the stenter chain. The residue must therefore be removed at regular interval by actuating the brush system.Main track guide selvedge feeder: The width of the in feed track is controlled by the selvedge feeder when there is no f/c in the m/c the chain track run with the activated feeders swung fully increases.
44
Rotary compensator: Is used even running speed it is infinitely pneumatic variable so that necessary longitudinal tension can be produced in the f/c Rotary tensioner it can be infinitely by hand so that requisite longitudinal tension can be created via f/c friction.Break roller: When unbreaked the break roller is driven by f/c. actuating the pneumatic break slow the roller movement & thus increase the f/c tension.My-cock bent stretching (curved roll): The bent stretching to prevent fold & stretches out the edges of the f/c.depending on the type & design of the f/c ,the adjustment angle of the stretching roller can be varied while the f/c is running.Lifting device: The liquor can be lowered pneumatically so that internal element in the trough is easily accessible. This facilitates threading in of the f/c& simplifies the cleaning of the trough & internal element.Matex three roll padding mangle system: The rolls are press together by two pneumatic cylinder thereby pressing excess liquor out of the f/c.Spreading roller: This roller has severe like profile running out to the left & right.Drawing screens: The screens prevent fluffs, threads etc. carried by the f/c from entering the air circulation system. The screens are located on the suction duct depend on the type & design /the m/c may be equipped with fixed base screens which can be removed after opening the service doors or with auxiliary screen which can be removed during the m/c operation.Integrated suction ducts: The m/c is equipped with an integrated suction duct. The exhaust air volume can be regulated via mechanically adjustable air valves.Rip cord switch: The safety system comprised a ripcord switch located at the outlet of the stenter. Pulling the ripcord trips the emergency stops function for the whole m/c.Master switch: When the master switch is in the Zero position, all power to m/c is switched off. In this operation the master switch can be locked with a pad lock to prevent restarting.Compressed air maintenance unit: A separate maintenance unit is provided in the control desk to prepare the compressed air for the mangle pad. The maintenance unit consists of filter with water trap a compressed air oilier & shut off tap.Pinning unit: The function of two pinning unit is to position the fabric selvedge as closely & uniformly as possible in line with the pressed overfeed on to the tips of the pins on the rubber brush roller & the continuous shrink belt underneath.Heating system: It is based on the oil circulating heating .the machine should be heated up only with the stenter chains running. in the same way, the heated machine Should never be left for prolonged periods with the stenter chain stationary. for this reason heating is automatically switched off when the machine is stopped on machine, without bypass flaps, when the machine is empty, the air circulation fan & suction fans must continue to run for approximately 15 min. after switching off the heating in order to condensation of the vapour treatment chamber monforts stenter are therefore adequate control reserve. the large heating capacity allows the circulating air in Monforts stenter to be heated up very quickly from room temperature to the desired temperature .for physical reasons the circulating air heats up more quicker than the steel construction, so steel parts can therefore still be cold even when the circulating the air has already reached the desired treatment temperature when starting the machine, cold before the beginning of production, heat up the range without fabric to 250˚c at least one hour. After one hour the desired temperature can be set.
45
Cooling zone: The fan draws in the ambient air & blows it via the nozzle system as top & bottom air current on the fabric. The fabric is carried on the air current.
Sanforizing machine
Objective: The purpose of this machine is to provide the fabric with relaxation shrinkage so that it does not shrink during later washings. This finish also increases the lusture and softens the handle of the fabric.
The main function is to give shrinkage in the warp direction and fix it, until the next home wash, to avoid that the fabrics have any dimensional variation (shrinkage), and also improving the touch of fabric.
