INDUSTRIAL TRAINING Course Code: Tex -4036 INDUSTRIAL ATTACHMENT OF Givensee Group of Industries Ltd. 1
INTRODUCTION By achieving practical knowledge it is possible to apply the theoretical knowledge in the practical field. For any technical education, practical experience is almost equality necessary in association with the theoretical knowledge. The industrial attachment is the most effective process of achieving practical experience. University education provides us vast theoretical knowledge as well more practical knowledge, despite of all these Industrial Attachment helps us to be familiar with technical support of modern technology, suitability about various processing/operation stages. It also provides us sufficient practical knowledge about production management, productivity evaluation, work study, efficiency, industrial management, production planning and control, production cost analysis, inventory management, purchasing, utility and maintenance of machinery and their operation technique etc. The above mentioned cannot be achieved successfully by means of theoretical knowledge only. Industrial attachment makes us reliable and improves courage and inspiration to take self-responsibility. We had the opportunity to perform the industrial attachment with Givensee Group of Industries Ltd. During 42days (6-Weaks) long attachment, We studies the man, Machine, material expects of the Batching, Dyeing section (Knit fabric), Finishing section, Quality Control, Lab, Knitting section, store & inventory control of the mill. According to my studies there we have prepared the following report and would like to present. We have prepared this report according to the guideline given by the University authority, which will lead to a strong guideline and milestone for our future career. 2
Object of Industrial Attachment B. Sc. in Textile Technology is the combination of Theoretical knowledge along with the practical experience. We as the Graduates of Textile Technology must acquire adequate practical knowledge to combat with the challenge that we will face in future.

CHAPTER-6 PRODUCTION PLANNING & SEQUENCE & OPERATION 40
PRODUCTION PLANNING, SEQUENCES & OPERATION Introduction and Basic Procedure of Planning and Control: A planned work brings success. Without planning nothing is completed within the required time. So planning has its own importance which is intolerable. "Planning" gives a scheduled task and 'control' completes it successfully. But production planning and control is not an easy task. So Esquire Knit Composite Limited’s has a high-performance department called "Production Planning & Control". Its Basic working procedure is as follows – Taking orders from marketing division. Analyzing the orders. Planning for knitting the fabric. Planning for dyeing the fabric. Planning for finishing the fabric. It is only a basic procedure. It may change according to the type of order. Sometimes, order is places only for finishing the material or only for dyeing the white goods. Then some steps are omitted for planning procedure. Taking orders from marketing division: EKCL marking division supplies Fabric Orders to the EKCL Planning and control division by a special format. Analyzing the orders: This section analyzes the orders according to buyers, Order Quantity, type of orders (i.e. type of fabric, color to be dyed etc.), delivery date etc. Then it selects which M/C. to use, no of M/C. to use, time required for production etc. This section plans for required quantity of fabric to be knitted 41
(Order quantity + 6% of Order Quantity), knitting balance, fabric need to be dyed. Dyeing balance, RFD (Ready for delivery), RFD balance, delivered fabric and delivery balance. Planning for knitting: This section plans for knitting production. It selects machine for knit the fabric for specific type of fabric, type of yarn used, required GSM, width etc. It also gives delivery data for knitted fabric. It also places orders for buying of yarn from spinning mills by a specific schedule. Planning for dyeing the fabric: Production planning for dyeing is called 'Batch Plan'. According to the batch no. And color, width, style and construction the batch plan is made. For easy understand this section gives some 'ROUTE CARD.' cards. "ROUTE CARD' cards are serialized according to the priority of delivery. The batches and "ROUTE CARD ' cards also serialized as to dye light shade at first and lastly the dark shades, since faulty shades can be converted to dark color later. Planning for finishing the fabric: Finishing schedule is same as the dyeing. After dyeing the material goes to the finishing section with the batch plan. Finished data is written to the batch card and is informed to the planning section. However, this section always enforces to all the departments to finish all the works within the delivery time given by the buyers. This section delivers materials by truck, micro, air etc to the customer within the meantime. Thus it plays a very important role in the success of the company. 42

DESCRIPTION OF PRODUCTION PROCESS: 1. Firstly, knitting manager gets a production shit from the merchandiser as accordance as consumer requirements then he informs or orders production officer about it. Production officer informs technical in charge and knows about machine in which the production will be running. Technical in charge calls for leader of mechanical fitter troops, they two take decision about machine for production considering machine condition, production capacity, maintenance complexity, etc. Production officer with experienced mechanical fitter adjusts required stitch length and grey GSM for required final GSM. Supervisor checks daily production regularity and make operator conscious about finishing tin due time. Operators operate machine in high attention as if there were no faults in the fabrics. If he thinks or sure about any fabric fault, then he calls for the mechanical fitters in duty. Mechanical fitter then fixes it if he can or he informs technical in charge. Then he comes in spot. After required production and final inspection in 4-point system, they sent in dyeing section. 2. 3. 4. 5. 6. 7. PRODUCTION PARAMETER: Machine Diameter; Machine rpm (revolution per minute); No. of feeds or feeders in use; Machine Gauge; Count of yarn; Required time (M/C running time); Machine running efficiency 47

Method of Increasing Production 1. By increasing m/c speed: Higher the m/c speed faster the movement of needle and ultimately production will be increased. 2. By increasing the number of feeder: If the number of feeder is increased in the circumference of cylinder, then the number of courses will be increased in one revolution at a time. 3. By using machine of higher gauge: The more the machine gauge, the more the production is. So by using machine of higher gauge production can be increased. 4. By imposing automation in the m/c: a) Quick starting & stopping for efficient driving system. b) Automatic m/c lubrication system for smoother operation. c) Photo electric fabric fault detector. 5. By imposing other developments: •Using creel-feeding system. •Applying yarn supply through plastic tube that eliminates the possibilities of yarn damage. •Using yarn feed control device. •Using auto lint removal. 49
Description of Knitting Parts With Figure: Name of the parts Picture Function Creel Creel is a part of knitting machine. Here yarn packages are stored for yarn feeding in the machine. MPF Wheel Its control the speed of the MPF. Pulley belt gives motion to the wheel. MPF It’s mean Mamminger positive feed. It gives equal length yarn distribution in the knitting cycle. VDQ Pulley It is a very important part of the machine. It controls the quality of the product. Altering the position of the tension pulley changes the G.S.M of the fabric. If pulley moves towards the positive directive then G.S.M decreases and reverse direction G.S.M will increase Pulley belt It controls the rotation of the MPF wheel. 50
