The circular knitting machine consists three major sections viz, yarn supply, knitting element and fabric take down.The needles are the most important stitch forming elements. They are displaced vertically up and down and are mounted into the tricks or cuts of the knitting cylinder.
The sinker is the second primary knitting element. It is a thin metal plate with an individual or a collective action operating approximately at right angles from the hook side of the needle bed, between adjacent needles.The knitting cams are hardened steels and they are the assembly of different cam plates so that a track for butt can be arranged. Each needle movement is obtained by means of cams acting on the needle butts.
Terry fabric is a knitted fabric with ring yarn or terry covering at one or both sides. It belongs to one of the fancy knitted fabrics. Terry fabric is characterized by soft touch, thick texture, excellent water absorption and heat retention. Terry fabric can be divided into single-sided and double-sided terry loop fabrics. The terry can form pattern effect on the knitting surface distributed according to some certain rules. Terry fabric after shearing or other process can be turned into fleece fabric or velvet fabric.
Pile fabrics: Manufacturing methods include woven pile fabric formation & others methods such as knit pile fabric, tufted pile fabrics etc. A "Terry" or a "Terry Towel" as is generally known is a woven pile fabric formed by slack tension weave process. of weaving.
Warp knitting is a family of knitting methods in which the yarn zigzags along the length of the fabric, i.e., following adjacent columns ("wales") of knitting, rather than a single row ("course"). For comparison, knitting across the width of the fabric is called weft knitting.Warp knitting machines--needles are mounted collectively and rigidly in a horizontal metal bar (the needle bar that runs the full knitting width of the machine).

Different parts of knitting machine and parameterAzmir Latif Beg
Knitting machines are mainly two types; they are circular knitting machine and flat bed knitting machine. This two types are hugely use in knitting machine. A knitting machine is composed of lots of parts. Every parts of a machine are important for run the machine smoothly. Every part has a specific function during operation.
Effect of machine parameters on knit fabric specificationstawfik_hussein
Effect of Machine Parameters on Knit Fabric Specifications
Cotton knit fabrics of yarn count 16Ne, 20Ne, 26Ne, 30Ne, 40Ne and 120-200 GSM for plain, 165-280 GSM for rib, 205-250 GSM for interlock were investigated with different machine parameters. The investigation developed a way so that it can be visualized or can forecast the resulting fabric specification with required configuration. The research emphasized on the adjustable points on which fabric GSM, stitch length, fabric width, and compactness directly or indirectly depends. It can be approached that the yarn count increases with the machine gauge. At different ranges of GSM the variation of the finished fabric diameter with the machine diameter is different. From a constant, VDQ number can be obtained for a particular stitch length and fabric design. Key Words: GSM, Stitch length, Yarn count, Fabric Width, Machine gauge, Needle.

Denim-Non Denim garments shade control systemAzmir Latif Beg
Shade control policy is very important to ensure one shade in one Carton specially for denim and Non denim. Its also determine shade variation within one destination or PO. Piece to Piece variation common problems found in garments due to fabric problem, mishandling of fabric rolls during cutting fabrics and bundles in sewing floor, wash problem etc.
Lycra void, damage and precaution to avoid those in washingAzmir Latif Beg
There is a lot of factor are involve behind of lycra damage. By the following preventive monitoring in every step of our manufacturing process we can get improvement all over the standard level and will be able to overcome those kinds of unwanted issues.
Mainly we have done visual inspection first after fabric received commonly follow 4 point inspection system. It's cover count/construction, width, weight, color, shading, design, measurement specifications, hand/feel and other specific quality parameters laid down by the clients.
Industrial Hazards and Their Safety Measure in Textile IndustryAzmir Latif Beg
Industrial hazard may be defined as any condition produced by industries that may cause injury or death to personnel or loss of product or property. Textile industries involve diverse operations including fiber synthesis, weaving, manufacturing, dyeing and finishing. Textile operations have been studied extensively and found numerous health and safety issues associated with the textile industry.
The ZDHC MRSL is intended to assist the apparel and footwear supply chain in phasing out the use of restricted substances by establishing enforceable limits for hazardous substances in chemical formulations used to process materials. The MRSL limits are designed to eliminate the possibility of intentional use of listed substances.
Risk Phrases (R) and Safety Phrases (S) is an important part of Chemical MSDS and Safety data sheet. We can identify hazard of a chemical by this phrases. Hazard classification should be indicated with hazard signs and hazard symbols and/or R phrases as well as S phrases.
R phrase and R number: phrases indicating the risks of hazardous preparations and substances, and their numbers respectively.
S phrase and S number: phrases related to the safe handling of hazardous preparations, and their numbers respectively.
Chemical Management System in Textile Manufacturing and Processing is required to achieve the safe use of chemicals and to control the hazards that they present to workers, the community and the environment. It can take a lot of chemicals to make clothes. The apparel sector certainly is not as chemical intensive as other global industries, but its variety of chemical operations and materials does present a range of potential hazards to its workers and the surrounding communities and environment.
NDT-Nondestructive testing is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.
Cotton fiber-textiles touch every aspect of our lives. For years, cotton clothing, home furnishings and industrial goods have enhanced our quality of life by providing comfort, expression and individuality.

Letters of credit is a written commitment to pay, by a buyer's or importer's bank (called the issuing bank) to the seller's or exporter's bank (called the accepting bank, negotiating bank, or paying bank). It is also known as a documentary credit.
Merchandising Transactions and Managing Payment RiskAzmir Latif Beg
The truth is that every payment method involves risk. Managing payment risks in merchandising transactions is very important. The major risks are fraud and operational risk.
Steam distribution system, utilization and designAzmir Latif Beg
n any steam plant or any process plant effectiveness of steam distribution system is dependent upon the project specific conditions like location and layout of the process plant and its steam consuming equipment like heat exchangers, decorators etc. Steam distribution circuit is one of the major link between the steam production point and the point of end use i.e. process plant. Primary steam generating source are co-generation plant and Steam generators. However it not the source of steam generation but the effective and efficient steam distribution system that decides right quality (pressure and temperature) and quantity of steam to reach to the process through it. Thus designing of steam distribution is to be given due importance along with installation and subsequently maintenance during operation.
A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. There are so many standards /test methods for textile testing.
In the present day world most of us are very conscious about our hygiene and cleanliness. Now a days Textile materials facing commonly mold problem during in store, in packed garment or in shipment container are not only related to microorganisms such as pathogenic bacteria, odour generating bacteria and mould fungi, but also good media for growth of microorganisms.
Fourier Transform Infrared Spectrometry (FTIR) and TextileAzmir Latif Beg
Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. FTIR offers quantitative and qualitative analysis for organic and inorganic samples. Fourier Transform Infrared Spectroscopy (FTIR) identifies chemical bonds in fiber. By FTIR we only know the name of fiber is identified. By this technique we can identify the exact composition of fiber like 80 % polyester 20 % cotton.
There are many safety issues, such as fire, fall accidents, choking, chemical content, etc. It can advise you on which requirements to request with the help of EU regulations related to Product Safety. It is an independent documentation of the safety of your products by ensuring that they comply with EU standards.
Flat knitting is a method for producing knitted fabrics in which the work is turned periodically, i.e., the fabric is worked with alternating sides facing the knitter. A "Flat" or Vee Bed knitting machine consists of 2 flat needle beds arranged in an upside-down "V" formation.
A braiding machine is device, which interlaces at least three strands of yarns or wires to form a rope reinforced hose, covered power cords, and some types of lace. Materials include natural and synthetic yarns, metal wires, leather tapes and others.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
