  15. 15. Knitting is the method of creating fabric by transforming continuous strands of yarn into a series of interlocking loops, each row of such loops hanging from the one immediately pre-ceding it. The basic element of a knit fabric structure is the loops intermeshed with the loops adjacent to it on both sides and above and below it. The weft knitted structure is very different from the warp knitted one. The difference is ap-parent from both warp and weft knitted structures is shown in simplest forms in below. It is seen from this figure that in a knitted structure a horizontal row of loops can be made using one thread and the thread runs in horizontal direction. In a warp knitted structure, each loop in the horizontal direction is made from a different thread and the number of threads used to produce such a fabric is at least equal to the number of loops in a horizontal row. One can say that in a warp knitted fabric the threads run roughly in a vertical direction.
  16. 16. Northern Fashion Ltd. has a state-of-the-art Weft Knitting Section. It has two knitting unit that is known as knitting – 1 and knitting – 2. The capacity of the knitting section has been rated annually as 900,000 kgs of grey fabric.

  21. 21. Specification of Knitting Machine: Others Equipments Used In Knitting Section: GSM cutter Electronic balance Inspection m/c Raw Material of Knitting Section:
  22. 22. There are two types of raw material that is yarn & Elastane. Brand name & origin of the yarn & elastane that is used in Northern Fashion Ltd. is given below- Types of Fabric: Single jersey & Double Jersey derivatives that is familiar in Northern Fashion Ltd. is given below- Single jersey Derivatives 1 Single jersey with lycra and without lycra 2 Single lacoste with half feeder lycra ( in lacoste never used full feeder lycra) 3 Pique & double lacoste 4 Two thread terry 5 Denim single jersey 6 Three thread fleece

Gauge,N = How many needles are used in one English inch (25.4 mm ). Number of needles N = One English inch. Number of needles N = mm. 2.54 Highest needle gauge is about 60 and lowest gauge is about 2 to 2.5. GSM: GSM means the weight in gram of one square meter fabric. Mainly it is measured by GSM cutter & electric balance.
  24. 24. Selection of machine gauge depends upon yarn diameter. Yarn diameter also depends on sev-eral factors such as yarn count, fibre type, yarn finishing etc. general practice of yarn count and machine gauge in different industries in Bangladesh given below: Yarn count used Machine gauge Yarn count used Machine gauge 16 18 28 22 18 20 28 25 20 20 28 28 20 24 30 22 24 22 30 24 24 24 30 28 26 20 30 34 26 22 34 28 26 24 34 28 26 28 The above values may differ, because it is the results of a research work. There is a relation between yarn in tex and machine gauge is given by equation, 1650 1400 For Single Jersey, G = and for Double Jersey, G = , where G is measured Tex Tex in needles per cm.
  25. 25. The yarn count to be used on a circular knitting machine depends largely on the pitch, and thus on the machine gauge. For any given machine gauge it can lie within a larger range, be-cause on the same machine different yarn counts can be used, depending on the knitted struc-ture, the desired optics (fabric appearance) and the fabric properties. Needle Pitch: The needle pitch is the distance between two neighboring needles in the same needle bed (bar), from the centre of a needle to the centre of the neighboring needle express in mm. Needle Pitch (Length units / Needles )= Needlegauge 1 (length unit ) Loop or Stitch Length: The length of yarn knitted into one stitch in a weft knitted fabric. Stitch length is theoretically a single length of yarn which includes one needle loop and half the length of yarn (half a sinker loop) between that needle loop and the adjacent needle loops on either side of it. Gen-erally, the larger the stitch length the more elastic and lighter the fabric, and the poorer its cover opacity and bursting strength. Stitch Length, l = One needle loop + Two half a sinker loop Yarn count is a numerical expression of fineness or coarseness of yarn. Yarn count is calculated in two systems: Direct system Indirect system Suitable Yarn Count Selection: Yarn count is selected by following equation- For Single Jersey:
  26. 26. Suitable Yarn Count ( Ne )= 4320 Finish GSM For Rib (1×1): Suitable Yarn Count ( Ne )= 6000 Finish GSM For Interlock (plain): Suitable Yarn Count ( Ne )= 7200 Finish GSM Production Calculation: It has been expound in the sections above that the output of a circular knitting machine de-pends on a series of different influencing variables. A wealth of machine data and data on the fabric to be produced is required for calculating production capacity. In this respect the cylinder diameter d in inch, the gauge E, the system count S, the machine rpm n, and the efficiency level ɳof the circular knitting machine must be known. The follow-ing data on the fabric produced must also be available: The construction (e.g. single jersey , rib, purl etc.) The course density or course /cm and the weight per unit area in gm/m 2 . Production is calculated in accordance with the following equation- Machine rpm × No. of feeder × Effciency × 60 Running Length (L) = m / hr No.of feeders per course × courses per cm ×100 Cylinder Diameter in inch ×π × MachineGauge Fabric width (WB) = Meter

  36. 36. Mainly dyes, chemicals and grey fabrics are raw material for dyeing & finishing. Grey fabric is supplied from knitting section. Name of dyes & chemicals that is used in Northern Fashion Ltd. are given below- Chemicals List:
  37. 37. The things which influence the effective coloration of textile materials with reactive dye are called as parameters of dyeing. These include –Temperature, Time, Liquor ratio, pH of the bath etc. A brief description about them is given below- Effects of Temperature: Temperature of the dye bath plays vital role for dyeing. Rise in temperature has a large effect on an increase in the diffusion rate of dyes into fabrics. Increasing of temperature increases the rate of dyeing & of the dye migration. Higher dyeing temperature ensures the good leve-ling & better penetration of dye in to the fibers. But the temperature depends on the types of dyes adapted in the dye bath. For Example-in case of hot brand dyestuff the dosing tempera-ture of dye is 80ºC and for cold brand dye temperature is kept 60ºC. Effects of pH: In the case of most popular fiber reactive dyes, a high PH actually activates the cellulose (cot-ton) fiber, forming a cellulosate anion, which can then attack the dye molecule, leading to a reaction that produces a strong, permanent covalent bond. Without a high pH, the dye will not fix permanently to the cellulose fiber. For this reason Sodium Carbonate (Na2CO3) [Some time mixed alkali such as (NaOH + Na2CO3)] is used for no other reason than to increase the PH of the dye reaction, so that the fiber will react with the dye. Basically during the color ad-dition, the PH of the bath remains at near about 6, but after adding alkali it goes rise to pH 11.4 & this is the critical stage in which the dye molecules fix up with the fiber. Effects of Material: Liquor Ratio (M : L): Dye bath exhaustion increases with the decreasing of liquor ratio. Dyeing at low liquor ratio decreases the amount of waste dyes & chemicals in the effluent. Because higher the liquor ratio greater the amount of g/l of chemicals which increases the volume of effluent. To get rid from this problem Then Air flow Dyeing machine is getting popular in our country which can dyeing at 1:3 Materials: Liquor ratio. But in case of Thies Jet Dyeing machine it can possible up to 1: 5 Materials: liquor ratio. Effects of Time: The time for dyeing also the vital one. A specific Time adjusted with the temperature, very much needed for better dyeing. For this reason color dosing takes place in 20 minutes (may
  38. 38. vary process to process) & Specific run time is set for dyeing. A dimensional change resulting in a decrease in the length or width of a specimen subjected to specified condition is known shrinkage. Spirality: If the wales of the knitted fabric are not perpendicular to the course and skew to the right or left spirality occurs in the fabric. This creates serious problem, especially in the apparel in-dustry. Dyeing Calculation: g/ l ×Total liquor Required chemical = Stock Soluation % ×1000 Required Dye = Material weight ×Shade % Conversion of % to gm/l: X ×10 X%= { }gm/ l Liquor ratio (only L value) Conversion of gm/l to %: X × Liquor ratio (only L value) X gm / l ={ }% Liquor ratio (only L value)
  39. 39. Laboratory: Lab is the most important section of a dying industry. Higher precision lab can aid easily to achieve the goal of the organization. Before bulk production a sample for the approval from industry is sent to the buyer. As per requirement of the buyer the shade is prepared in a lab considering the economical aspect. The Main Objectives of a Textile Dyeing Laboratory: To develop standard operating procedures (SOP) for all the products which are to be processed in a dye house. Dyestuffs evaluation. Color matching together with process and product development. To provide training ground for production and laboratory technicians. Process optimization and cost reduction through process modifications and develop-ing or testing newer techniques and products. In process checks of important quality parameters affecting the quality, efficiency, cost etc and monitoring. Quality control of all raw materials consumed and also all processed material in terms of color and fastness. NORTHERN FASHION LTD. Machinery Layout Plan of Dyeing Lab

  45. 45. Grey Fabric Store & Batch Section: In Northern Fashion Ltd. Grey fabric store and Batch section works along with. Where the fabrics are arranged by type of fabrics & buyer order after completing grey fabric inspection. Fabrics are separated by roll or lot. Every face of lot or rolls contains Fabric types Yarn count Fabric GSM Fabric faults name Lot number Roll number This section maintains a card for every lot which contains the information about fabrics.
  46. 46. Batch section is a vital section for fabric dyeing. Batching is a separation for fabrics roll ac-cording to dyeing machine. Normally its separation depends of the number of nozzle. This section is always tried to give same weight of fabrics for every nozzle. Function of Batch Section: To receive the grey fabric roll form knitting or other source.Turn the gray fabric if require. Prepare the batch for dyeing according to the following criteria:-Order sheet (Received from buyer)-Dyeing shade ( light or dark, color or white)-Machine capacity.-Type of fabric ( 100% Cotton, CVC, Stripe fabric)-Fabric dia. and rope length-Emergency order.-Fabric construction (single jersey, Rib, Lycra Rib, Lacost, PK etc.) To send the grey fabric to the dyeing floor with batch card. To keep record.
  47. 47. To try same rope length for each nozzle. To use maximum capacity of existing dyeing machine. To minimize preparation time & machine stoppage time. To use a particular machine for dyeing same shade. Turning machine This tubular turning machine is for turning tubular knit fabric before dyeing and drying after. As knit fabric material is handled by the air force, there is no fear of damage during opera-tion. Speciation: Made of stainless steel, the main pipe can stand up permanently without rusting. Operation is easy and safe. Air flow initiation or termination is instantly effected by the press of the ON or OFF push-button, or the moment the material fabric reaches the eject roller. There is no lingering air consumption. Air flow direction is designed to automatically switch upon alteration of the position of the curved pipe, as they are interlocked with each other.
  48. 48. Dyeing Machine:
  49. 49. DMS 11 HT JUMBO FABRIC DYEING MACHINE (RDS) HT Jumbo is a winch dyeing machine. HT Jumbo is designed and manufactured with the lat-est high technology for dyeing any kind of open width fabric made of natural, synthetic and their blends such as open width knitted cotton and cotton lycra, viscouse and viscouse lycra and all kind of towell fabric and bathmad etc. DMS 11 JUMBO (RDS) presents the latest technical achievement on dyeing both knitted and woven fabrics to produce high quality level materials at a compatible cost. DMS 11 HT JUMBO is able to process fabrics in the range from 70 g/m up to 2300 g/m in weight by choosing the right nozzle say. Machine is available in various capacities starting from 25 Kg upto 2000 Kg on both high and low temperature design. Machine`s body and all wetted parts made of highly corrosion resisted stainless steel AISI 316 L, in accordance with American ASME and European (CE) norms.
  50. 50. Dyeing & Finishing The basic principle of DMS 11 HT dyeing machines is to have a number of loops or
  51. 51. ropes of the fabric in the dye bath, these ropes are of equal length, which are mostly immersed in the liquor in the bath. The upper part of each rope runs over two reels which are mounted over dye bath. At the front of the machine, above the top of the dye liquor, is a smaller reel, which is called jockey or fly roller. The fly roller remains freewheeling along with fabric rope. At the back of winch tank is the winch wheel, which pulls the fabric rope from the dye bath over the jockey reel for dropping in the dye bath for immersion. From the dropped location, the fabric rope travels back. To be lifted and fed to winch wheel. The dyeing process on winch dyeing machines is based on higher M: L as compared with other dyeing machines. The process is conducted with very little tension. Material Safety Data Sheet (MSDS) for Dyeing Machine: Work should be done before running machine. 1 Clean the machine. 2 Clean additional tank & filter. 3 Switch ON the main switch. 4 Open the steam, water & air bulb. 5 Run the machine. 6 Check the pneumatic bulb is it work properly 7 Have any bad sound in machine? Check it. 8 Start the production process 9 Close the all bulb after ending the process. 10 Switch OFF Emergency switch. 11 OFF the main power 12 Don’t touch electric switch on wet hand. 1 Machine should be kept always clean. 2. Before opening machine door or reel following point should be considered-
  52. 52. a. Machine pressure should be at 0. b. Temperature should be below at 80ºC c. Water level should be kept under machine door. 2 Electric component should be safe from water during machine cleaning. 3 After cleaning machine filter dust should be kept in specific drum. 4 If any problem is observed in dyeing machine, the information should be sent to maintenance department as soon as possible. Operator must not be accessed electric control panel in any condition. 5 After ending process and before going operator must be clean the machine. 6 If it is needed that machine will be stopped for few days, machine should be kept with filling water upto midlevel. Rope Opening, Slitting & Dewatering Machine: Slitting is a process that is applied for cutting the tubular fabric through the intended brake Wales lime on length wise direction prior to stenter processing.
  53. 53. Machine Function: Open the fabric from the rope form.Reduce the water contentTo slit the fabric from tube formApply overfeed to give some compaction.Width-wise stretch the fabric.Plait the fabric J-Box: Squeeze the fabric to reduce the water contains. Water reducing percentage depends on J-Box pressure. Detwister: By the detwister rope formed fabric become untwists form. (due to action of sensor) Hand Wheel: It is manual and used for guiding the rotary blade. Turn Wheel: It controls the fabric rotation Rotary Blade: To cut the fabric through break wales line. Ring: To help cutting. Guide Roller: To guide the fabric to plaiting Plaiter: To plait the fabric. Sensor: Sense for cutting through break wales line. Basic Operation Principle:

Basic Working Principal of Stenter: The stenter line has units: 2 padders, 1 weft straightener, 1 tenter and drying chambers. There are also steaming, selvedge degumming and curing arrangement. At least padder is simply wash with water. The squeeze pressure normally 5 bars. In two padder the fabric is treated with softener. The fabric is passed through tenter. There are two steams along fabric width that apply steam from below fabric. There are gumming unit before drying chamber. In sten-ter, fabric enters in drying chambers by gripping with chain pin and with over feed/ under feed that is with more controlled conditions. The drying chamber has 7 units. Generally tem-perature kept about 150 – 200 ºC. The fabric comes out form chamber by tenter chains grip-ping with pins. Before delivery the fabric is removed from the tenter chains by unpinning rollers and then the cutting units cut the additional fabric from the gummed sides. Now at de-livery side there is an antistatic arrangement to remove static electricity from heated fabric. Function of Stenter: Apply chemical and softener To dart set the T/C fabric Drying of fabric To control width Curing of fabric Apply pigment dyeing To control GSM To control shrinkage To decrease spirality To decrease bowing effect Surface coating for teflon finish Apply soil release chemical finish Heat set for cotton/lycra fabric

  101. 101. Process description The effluent from different sources will be collected in an Equalization tank through a Bar Screen. Bar Screen will remove large floating materials. The equalized effluent is then pumped to a Flocculation tank. Coagulation agents, like Lime, Alum and Polyelectrolyte will be dosed in the Flocculation Tank to agglomerate the suspended particles. The effluent from this tank will pass through the Primary Tube Settler where flocks are removed. After primary tube settler, the effluent flows to the Aeration Tank, where BOD & COD are removed. The pH of the effluent will be corrected to bring to the level of 8 to 8.5. After Aeration Tank, the effluent will pass through a Secondary Clarifier where suspended biological solids are re-moved. From Secondary Clarifier, the effluent will be discharge to drain. Sludge generation from primary clarifier will be taken to sludge pit or sludge drying bed. From sludge pit sludge will be fed to centrifuge followed by filter press unit. Sludge cakes generation from filter press will be dried and can be disposed suitably. Sludge from second-ary clarifier will be re-circulated back to aeration tank and periodically to sludge pit.

Above given figures of chemical consumption will get reduced if the sewage dis-charge is added.
  104. 104. In case it is not possible to provide sewage discharge to the plant, then some di-ammonium phosphate & urea will be required at time of commissioning. Water treatment plant: Water for a textile plant may come from various sources .These includes surface water from rivers and lakes, and subterranean water from wells. The various salts present in water depend on the geological formations through which the water has flowed. These salts are mainly the carbonates (CO3 2- ), hydrogen carbonates or bicarbonates ( HCO3 - ), Sulphates ( SO4 2- ) and chlorides ( Cl - ) of calcium ( Ca 2+ ), magnesium (Mg 2+ ) . Although calcium and magnesium carbonates in limestone are relatively insoluble in water. So in this reasons, water hardness can be divided into two ways 1) Temporary hardness : Ca(HCO3)2 , Mg(HCO3)2 , Fe(HCO3)2 2) Permanent hardness : CaCl2 , CaSO4 , Ca (NO3)2 , MgCl2 , MgSO4 , Mg(NO3)2 This water hardness causes some serious consequences in a textile dyeing and finishing industries and these are 1 Precipitation of soaps . 2. Redeposit ion of dirt and insoluble soaps on the fabric being washed , a. this can cause yellowing and lead to uneven dyeing and poor handle. 2 Precipitation of some dyes as calcium and magnesium salts. 3 Scale formation on equipment and in boilers and pipelines. 4 Reduction of the activity of the enzymes used in washing. 5 Incompatibility with chemicals in finishing recipes and so on. Hardness expressed by parts per million (ppm) of CaCO3 which is standard hardness scale and it is also called American hardness. Capacity: 60m³ per hour

Conclusion:
  109. 109. Technical education and its adoption in practical field. Inextricably , without the implemen-tation of the knowledge gathered in technical education its success bound to suffer . Therefore , this two months long industrial as a partial fulfillment of our B.Sc in tex-tile Engineering course helped us to accomplish the gap between the theoretical and practical knowledge by providing an elementary idea about industrial environment processing machines , tools , equipments production system and maintenance , administra-tion and management system . We completed our industrial training at Northern Fashion Ltd. It was established just a few years ago with latest model of different machinery within a very short time it earned name and fame at home and abroad for its quality in production and administrative facilities . The industry has been a setting up of a 100% export oriented composite knit gar-ment unit. The project is set up with Knitting, Dyeing finishing and garments facilities. Two month is not long period and it not sufficient time to learn all area in a factory but can achieve an idea and can introduced with factory environment. In factory all the employs were very busy to his/ her own responsibility, so they cannot supervise us properly, but they were very cordial to us. Northern Fashion Ltd also called a training house of Textile Engineer. At our training period we gather some knowledge which can be play a vital role in our pro-fessional life. Beside the theoretical knowledge, by industrial training a student can increase his/her knowledge properly. At training period if a student can supervise by a experience person at industry with university he can appropriately learn vast knowledge. We successful-ly completed our training, we try to gather all necessary information but it is true that within this short period it is quiet impossible to achieve 100% success but as a whole this industry training was a satisfactory one again I would like to thank the authority of Northern Fashion Ltd. as well as my honorable teachers for their altruistic help and advice .
