HURRICANE DYEING & PRINTING (PVT.) LTD. Page 20 of 147 Bengal Hurricane Dyeing & Printing(Pvt.) Ltd.is a famous composite textile industry in Bangladesh located at Monipur, Gazipur, Dhaka. BHDP is producing different types of knitted fabric with great excellence. They are also performing dyeing, printing, finishing and garment manufacturing operation and supplying products to the International Buyers. Single jersey, Single locust, Rib, Interlock etc are common type fabric produced by BHDP. There are two types of knitting machine in BHDP they are; Circular knitting m/c and Flat bed knitting m/c. The no. of circular knitting m/c is 36 and no. of flat bed knitting m/c is 6. All the knitting m/c’s are active and working with good performance. Among the 36 circular knitting m/c’s they are from 5 different company as Fukahama, Terrot, Jumberca, Tien Yang and Wellknit and among 28 flat bed knitting m/c’s they are from different company like ProttiFashiontronix, Kauoheng, JY-LEH etc. The dia and gauge of different circular knitting m/c are different like 20”/24G, 21”/24G, 22”/24G, 23”/24G, 24”/24G, 25”/24G, 26”/24G, 28”/24G, 30”/18G, 30”/24, 30”/32G, 32”/24G, 34”/24G, 36”/18, 36”/24G, 36”/18G, 36”/28G. There are 5 Rib m/c (m/c no. 12,13,14,15,22,), 1 Interlock m/c (m/c no. 21) and rest 30 m/c’s are single jersey. Among the 30 single jersey m/c there are 4 open width single jersey m/c,4 Engineering Stripper. The open width single jersey m/c produces knitted fabric in open width but they can also be used to produce tubular knitted fabric by changing some simple mechanism. BHDP is using different types of yarn of different count for their production of different types of fabric. The common counts of yarns are 20, 22, 24, 26, 28, 30, 32, 34, 40 etc. The yarns are different types in properties like carded, combed, CVC,slub, millange, blended,nepetc BHDP is mainly producing different types of knitted fabrics such as Single Jersey, Single Locust (With and Without Lycra), Rib (1*1 and 2*2) (With and Without Lycra), Polo Pique, CVC Fleece, terry, 100% Polyester Fabric, Grey Melange, Interlock etc. Knitting is a method by which thread or yarn is turned into cloth or other fine crafts. Knitted fabric consists of consecutive rows of loops, called stitches. As each row progresses, a new loop is pulled through an existing loop. The active

HURRICANE DYEING & PRINTING (PVT.) LTD. Page 21 of 147 stitches are held on a needle until another loop can be passed through them. This process eventually results in a fabric, often used for garments. 2.4Classification of Knitting 2.5Knitting Structure Course and Wales Like weaving, knitting is a technique for producing a two-dimensional fabric made from a one-dimensional yarn or thread. In weaving, threads are always straight, running parallel either lengthwise (warp threads) or crosswise (weft threads). By contrast, the yarn in knitted fabrics follows a meandering path (a course), forming symmetric loops (also called bights) symmetrically above and below the mean path of the yarn. These meandering loops can be stretched easily in different directions, which give knitting much more elasticity than woven fabrics; depending on the yarn and knitting pattern, knitted garments can stretch as much as 500%. For this reason, knitting was initially developed for garments that must be elastic or stretch in response to the wearer's motions, such as socks and hosiery.

HURRICANE DYEING & PRINTING (PVT.) LTD. Page 22 of 147 There are two major varieties of knitting: weft knitting and warp knitting. In the more common weft knitting, the Wales are perpendicular to the course of the yarn. Weft-knit fabrics may also be knit with multiple yarns, usually to produce interesting color patterns. The two most common approaches are intarsia and stranded color work. In intarsia, the yarns are used in well- segregated regions, e.g., a red apple on a field of green; in that case, the yarns are kept on separate spools and only one is knitted at any time. Circular Knitting Circular knitting or knitting in the round is a form of knitting that creates a seamless tube. When knitting circularly, the knitting is cast on and the circle of stitches is joined. Knitting is worked in rounds (the equivalent of rows in flat knitting) in a spiral. Originally, circular knitting was done using a set of four or five double- pointed needles. Later, circular needles were invented, which can also be used to knit in the round: the circular needle looks like two short knitting needles connected by a cable between them.Longer circular needles can be used to produce narrow tubes of knitting for socks, mittens, and other items using the Magic Loop technique. Flat Knitting Flat knitting is a method for producing knitted fabrics, in which the work is turned periodically, i.e., the fabric is knitted from alternating sides. Flat knitting is usually contrasted with circular knitting, in which the fabric is always knitted from the same side. Flat knitting can complicate knitting somewhat compared to circular knitting, since the same stitch (as seen from the right side) is produced by two different movements when knitted from the right and wrong sides. In flat knitting, the fabric is usually turned after every row. However, in some versions of double knitting with two yarns and double-pointed knitting needles, the fabric may turn after every second row. Knitting Variables Yarn Count Yarn Twist

Page 23 of 147 Spinning System Yarn Ply Stitch Length Yarn Tension Take Down Tension Machine Gauge 2.6Various Terms Used in Knitting Course: Horizontal row of loops produced by adjacent needles in knitting cycle is called the course of the fabric. A course is a predominately horizontal raw of needle loops produced by adjacent needles during the same knitting cycle. Wales: Vertical column of loops produced by same needle in knitting cycle is called the wales of the fabric. Number of vertical columns of loop of knitted fabrics is called wale. Face Loop: If the legs of new loop are passes over the old loop is called face loop. Back Loop: If the legs of new loop are passes under the old loop is called back loop. Stitch Density: The term stitch density is frequently used in knitting instead of a linear measurement of courses or wales; it is the total number of needles loops in a square area measurement such as a square inch or three square centimenters.It is expressed as: Course per inch × Wales per inch Stitch Length: Length of one loop in the course direction express in mm. Number of Needle: Machine Diameter × Machine Gauge × 3.1416 Cam: Cam is the specific path of needles to produce a specific type of fabric.There are three types of cam used in circular knitting machine; 1. Knit Cam 2. Tuck Cam 3. Miss Cam Knit Cam: It moves the needle upward enough to clear the old loop receive the new yarn. Tuck Cam: It moves the needle upward not enough to clear the old loop but receive the new yarn.

HURRICANE DYEING & PRINTING (PVT.) LTD. Page 24 of 147 Miss Cam: It does not move the needle upward. The needles neither clear the old loop nor receive the new yarn. Needle:A knitting needle or knitting pin is a tool in hand-knitting to produce knitted fabrics. They generally have a long shaft and taper at their end, but they are not nearly as sharp as sewing needles. There are three types of knitting needle- 1. Latch Needle 2. Bearded Needle 3. Compound Needle Latch Needle is four types- One Butt, Two Butt, Three Butt and Four Butt Needle. Sinker: It is a thin metal plate with an individual or collective operation approximately at right angles at the hook side between adjacent needles. Function of Sinker: In circular knitting machine sinker helps to form the loop by holding down the yarn. Needle Gauge:The needle gauge of a knitting machine is a measure expressed the no. of needle per unit of the needle bed or needle bar. As for example: 1. In case of circular weft knitting machine &Tricot warp knitting machine. [Gauge, N=Number of needle per inch] 2. In case of Raschel warp knitting machine [Gauge, N=Number of needle per two inch] 2.7Classification of Knitting Section The knitting section of Bengal Hurricane Dyeing & Printing(Pvt.) Ltd.(Knitting Unit) is divided into two parts although all the machines are placed into the same floor. The sections are- 1. Circular Knitting Section 2. Flat Bed Knitting Section

The grading has two primary functions: First, to classify the fabrics according to standard qualities based on the end-use and costumer demands and second, to supply information as to the qualities actually being produced. The Knitted fabric can be classified into three levels of quality, each one have a number of points for defects as follows. 3.4GENERAL INSTRUCTIONS FOR THE FINAL INSPECTION a) All pieces will be graded on the base of 40 points per 100 Linear yards Mapping will be done on each piece to insure proper grading. Do not count more than 4 points per one yard. b) All defects must be recorded and marked in final inspection and an accurate account of points made to insure proper grading. c) All fabric must meet specifications. d) At the end of each piece of fabric, the inspector will add up total points and decide whether the piece can be shipped as first quality or not, reworked, placed in lower quality, or cut and upgraded for shipment. Fifteen yards or more can be shipped as first quality. e) The quality control supervisor must approve the grading of all quality levels and check the lower quality. f) Major or unsightly defects in the first and last yard of a roll or piece will be cut. All defects of one yard length or more will be cut out of the piece. Defects within the first 2 inches or the last 2 inches of a piece will not be cut out or counted in the grading. g) Open defects on the back of fabric such as drops, runs and hanging picks are to be included in the grading of fabric. h) Pieces can be connected together, once each piece must be the same shade. i) All defects such as runs that extend more than a yard in length will be cut out.

HURRICANE DYEING & PRINTING (PVT.) LTD. Page 44 of 147 4.5 Lab dyeing process follows up The laboratory dyeing process of Bengal Hurricane Dyeing & Printing(Pvt.)Ltd. is as follow: Sample Received ↓ Standard is checked with the Reference from the inventory ↓ If matched then sample prepared from that recipe ↓ If not matched than the color percentage is calculated by using Data Color ↓ Recipe Prepared ↓ Sample prepared according to recipe ↓ Standard (From Buyer) and Sample prepared is Compared ↓ If Okay then the sample is sent to Buyer ↓ Buyer approves the sample and order for the bulk production. Sample Received: Buyer sends a sample which is considered as standard in whole process. Buyer also gives some requirements about the properties of the standard fabric. For example, Buyer wants good wash fastness, light fastness, rubbing fastness, pilling formation etc. The lab receives this standard to make this fabric according to buyer requirements. Standard is checked with the Reference from the inventory: The factory dyed a lot of fabric in its running years. It also stores a lot of sample in its inventory. The standard is first checked with the samples kept in the inventory. If matched then sample prepared from that recipe: If the standard is matched with the sample of inventory then the next process becomes easier. Because after matching the sample with standard previously maintained recipe is followed. If the sample does not match with the standard then the process goes to data color. I not matched than the color percentage is calculated by using Data Color: If the standard does not match with the samples of inventory, then the standard percentage of color is found out from the data color machine. Recipe Prepared:

Sample prepared according to recipe: Following the procedure the sample is prepared. Standard (From Buyer) and Sample prepared is Compared: After getting the sample is compared with the standard. And several tests are done to meet the buyer requirement. If Okay then the sample is sent to Buyer: Sample is then sent to the buyer for the final approval. Buyer approves the sample and order for the bulk production: When buyer gives the final approval the fabric is sent to production floor for the bulk production. 4.6 Properties test 4.7 Color fastness to rubbing (wet & dry): Procedure: Firstly a sample of size (14 × 5) cm is taken at Wales & Course wise. The crocking cloth is put on to the finger & is staged by finger clip & run 10 times in 10 seconds manually & assesses the crocking cloth with gray scale. The crocking cloth is placed on the water, it will suck some water and crocking cloth is then squeezed. Then place the wet rubbing cloth on to the finger and stag with finger clip and run 10 times in 10 seconds manually. The crocking is then assessed cloth by gray scale for wet rubbing. Wet and dry rubbing are checked according to buyer’s requirement. 4.8 Color fastness to washing. (ISO/05-CO6): Procedure: 1. Size of specimen: Sample &multifibre at (10 × 2) cm then stitch. 2. Detergent: 4g/l ECE detergent (WOB) + 1g/l sodium per borate put in distilled water & cooled at 20°C & measured PH (where necessary). 3. the program is run in the following way: - Test no. Temp°C Liq.volume ml Time min. Steel balls Adjust pH C2S 60°C 50 30 25 10.5±1 4. The sample is rinsed twice with cold water. 5. At 60°C by hanging or by flat iron pressing the dried but temperature should not less more than 150°C. 4.9Pilling test: Procedure: The fabric 12.5 x 12.5cm is cut & balanced mark should be 10cm by using template. Then the fabric is sewn so that it can be firmly fit in the tube a moulded polyurethane tubes. Then four tubes are placed in a box & started 60±2 rev/min for 5 hrs or according to buyer requirement.

Shrinkage: length wise--- 5% Width wise----5% Spirality: Left -------- 5% Right -------- 5% Procedure: Firstly two ply of fabric is taken & put the template (50cm) on to the fabric. The template has 8 holes. Both length & width wise the template holes can measure 35cm at 3 places. Then 8 holes are marked by permanent marker & also at the edges of the template. The fabric is sewn & it is given to the washing m/c for run at 60°C for 60minutes with water. After that the sample is dried & then fabric is measured. Calculation: Shrinkage Test: Lengthwise: After wash – Before wash = ----------------------------------×100 Before wash Width wise: After wash – Before wash = ----------------------------------×100 Before wash Spirality test: = M)&HforthLength(wid 2 sideRightsideLeft × 100 % 4.10 Dyestuff Strength test: Dyestuff strength test is very important for any textile dyeing industry. A dye comes to industry then a sample fabric is dyed first to make it a reference. When that dye is used and finished from inventory, new dye is ordered. But it is not sure the dye that reached newly, will make a fabric as much dyed as before. That is why after arriving of dye to the factory it is used to make a sample. Then this newly made sample is checked in respect of previously dyed sample. If the two samples match with each other, it is resulted that the strength is okay. But if not match then the amount to be given (less or more) is determined. Thus the strength of dyestuff is measured in this way.

HURRICANE DYEING & PRINTING (PVT.) LTD. Page 74 of 147 6.2 Introduction Textile finishing , in a restricted sense , is the term used for a series of processes to which all bleached , dyed , printed and certain grey fabrics are subjected before they are put on the market . In fact , finishing includes the final treatment of every kind of fabric made from every kind of fiber . According to Textile Terms and Definition the Finishing describe as, “Descriptive processes, physical or chemical, applied to a substrate to produce a desired effect”. Finishing is a chemical or mechanical process applied on textile goods after dyeing and printing process just to give it some quality development according to the demand of user or customer or buyer. In textile manufacturing, finishing refers to any process performed on yarn or fabric after weaving or knitting to improve the look, performance, or "hand" (feel) of the finished textile or clothing. Some finishing techniques, such as fulling, have been in use with hand-weaving for centuries; others, such as mercerization, are byproducts of the Industrial Revolution. Standard Finishes are different types like quality-oriented, design-oriented, and handle-oriented. There are also some special types of finishing process like bio- polishing, mercerization, raising, fulling, decasting, calendaring, sunforizing or pre-shrinking, peach finish, crease-resit finish, anti-microbial finish etc. Objective of Finishing: 1. Improving the appearance – Luster, whiteness, etc. 2. Improving the feel, this depends on the handle of the material and its softness, suppleness, fullness, etc. 3. Wearing qualities, non – soiling, anticrease, antishrink, comfort, etc. 4. Special properties required for particular uses–water–proofing, flame proofing, etc. 5. Covering of the faults in the original cloth. Types of Finishing: 1. Chemical Finishing: Permanent chemical finishing Temporary chemical finishing 2. Mechanical Finishing: Permanent mechanical finishing Temporary mechanical finishing Finishing Effects: Easy Care. Crease recovery. Dimensional stability. Good abrasion resistance. Improved tear strength. Good sew ability. Soft or stiff handle. Shine or luster.
