SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering INTRODUCTION By means of practical knowledge it is possible to apply the theoretical knowledge in the practical field. For any technical education practical experience is almost equally important in association with the theoretical knowledge. The industrial attachment is the process which builds understanding skill and attitude of the performer, which improves his/her knowledge in boosting productivity and services. Academic education provides us vast theoretical knowledge as well as more practical attachment, despite all these industrial attachment help us to be familiar with the technical support of modern machinery, skill ness about various operation stages. It also provides us sufficient practical knowledge about production management, Productivity evaluation, work study, efficiency, industrial management, production planning & control, production cost analysis, inventory management, purchasing, utility & maintenance of machinery and their operation techniques etc. The above mentioned cannot be achieved successfully by means of theoretical knowledge only. This is why it should be accomplished with practical knowledge in which it is based on industrial attachment makes us reliable to be accustomed with the industrial atmosphere & improve courage & inspiration to take self- responsibility.

SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering 1. G.S.M: The weight of fabric in gram per square meter is called G.S.M. 2. Yarn count: It is a numerical expression of coarseness or fineness of yarn which can be measured in two systems. One is direct system and another one is indirect system. For direct system: × Count = For Indirect System: × Count = × 3. 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 on needle loop & half the length of yarn (Half a sinker loop) between that needle loop & the adjacent needle loops on either side of it. Generally, the larger the stitch length the more elastic & lighter the fabric, & the poorer its cover capacity & bursting strength. 4. Fabric Width: Along the fabric width there presents the Wales. The total no. of needle is fixed for the same cylinder having the equal gauge as well as diameter. Fabric width = No. of Wales X Wales space. = No. of needle X Wales space. = Πdg X Wales's space. d = Cylinder diameter, 24 | P a g e S u b m i t t e d b y : M d .

SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering g = Gauge. The above concept clarifies that Fabric width closely depends on total no. of needle not directly related to machine diameter machine gauge. 5. Fabric Thickness: In the dry and wet relaxed states fabric thickness (t) is depends upon fabric tightness, but in the fully relaxed state, it is more or less dependent of the fabric tightness factor. In the fully relaxed state t= 4d. Where d is the yarn diameter For single jersey, t = 2d Technical Specification: 1. Machine gauge: No. of needles per inch present in a needle bed of a knitting machine is called machine gauge for that knitting machine. A term giving a notational indication of the no. of needles per unit length along a needle bed or needle bar of a knitting machine in current practice, a common unit length of one English inch (25.4mm) is used for all types of warp and weft knitting machine. Selection of machine gauge depends upon yam diameter. Yam diameter depends upon the following: 1. Yarn count. 2. Yarn type. 25 | P a g e S u b m i t t e d b y : M d .

SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering 2. V.D.Q Pulley (Variable Dia Quality): In a knitting m/c to supply the specific length of yarn, there are two or more adjustable pulleys which are known as V.D.Q. Pulley. By adjusting the V.D.Q. pulley we can control the speed of accumulator which supplies the required amount of yarn. V.D.Q. pulley is very important to set up the correct loop length. The amount of yarn wound on accumulator by one revolution of cylinder is called the course length of fabric VDQ Pully Measurement: For Orizio machine, . × VDQ = – 2 For an Exp: S.L = 2.90 No of needle = 2580 27 | P a g e S u b m i t t e d b y : M d .

SOUTHEAST UNIVERSITY School of Science and Engineering, Department of Textile Engineering Drive: Today the belt system has by far become most common positive feed system. The belt makes the spool rotate and the no of rotating spools corresponds to the no of feed systems. By adjusting the belt RPM, the quantity of yarn per loop can be increased or reduced. This system grants an accurate control of the yarn tension. We know knit loops more yarn than tuck loops. To produce this fabric we use 3 belt drive. Two drive for knit loops & one drive for tuck loops. Stitch length: Stitch length of each loop is controlled by VDQ pully . VDQ pully was adjusted to give 3.1 mm length for knit loops & 2.65 mm for tuck loops. Thus we produced the fabric. Lycra attachment: There are several methods to calculate lycra percentage in fabric sample. Some of them are described below- Manual method: 5 gm sample fabric is taken & withdrawn the lycra yarn from sample fabric Then the sample fabric is weighted. From difference weight, we calculate the lycra percentage of the sample fabric % ℎ ℎ − ℎ = ℎ ∗ 100% 34 | P a g e S u b m i t t e d b y : M d . K a m r u l H a s a n I D : 2 0 0 8 0 0 0 4 0 0 0 9 3
