Basic structure of a woven fabric
This document contains information about woven fabrics submitted by students Amit Biswas, Md. Ahasan Habib, and Tahmina Hossain Bristy to their lecturer Mr. Suja Ahmed Auporbo. It defines woven fabric as being made from two sets of warp and weft yarns interlaced at right angles. Woven fabrics are classified as having either a simple or compound structure. Simple structures use one set of parallel warp and weft yarns, while compound structures use more than one set of yarns including some for ornamental purposes. The document also describes and provides examples of various basic woven structures including plain weave, twill weave, satin weave
Satin and sateen weaves
Sateen and satin weaves produce smooth, lustrous fabrics. Sateen has a weft effect while satin has a warp effect. They are defined by their repeat (R) and shift (S), where the repeat is greater than 5, not equal to 6, and the shift is between 1 and R-1. Examples given are sateen 5/3 and 7/3. Sateen is denoted by a fraction where the numerator is the repeat and denominator is the shift. Satin and sateen weaves are used for applications like doeskin, linings, and bridal gowns. Variations can be made through additions or subtractions of floats in regular or irregular patterns
knitted fabric Manufacturing Process
This document discusses different types of knitting machines and fabrics produced on them. It describes single jersey, pique, and fleece fabrics which are produced on single bed needle machines. Double knit machines have two beds of needles and can produce interlock, rib, and double jersey fabrics. Three thread fleece is made on fleece machines and has long loops on the back side, allowing for high brushing. Characteristics of two thread and three thread fleece fabrics are provided such as weight, yarn used, and fiber percentages. Common issues that can occur with fleece knitting and their remedies are also outlined.

Importance, Effect & Testing of Yarn Evenness
This document discusses irregularity or unevenness of fiber, which refers to variations in mass per unit length of a fiber assembly. It describes two common methods for measuring irregularity - the irregularity U% and the coefficient of variation C.V%. Several methods for measuring fiber irregularity are outlined, including visual inspection, cutting and weighing, and various testing machines like the Uster Evenness Tester and photoelectric testers. Irregular fibers can affect yarn strength, fabric appearance, and dyeing/finishing. Maintaining low irregularity is important for quality control in textile production.
Different techniques of sizing
Before weaving, sizing of yarns are very important. During weaving the yarns experience heavy pressure, so in some cases, they may break. So sizing is necessary for improving the strength of yarns.
fabric structure and design
This document provides information on extra warp and weft figured fabrics. It discusses two methods of producing these fabrics: 1) using extra warp threads and 2) using extra weft threads. For extra warp fabrics, a separate warp beam is needed along with a dobby mechanism. For extra weft, a drop box mechanism is required. Both methods allow figuring in single or multiple colors. The document provides examples of motif designs and how the ground and extra threads interlace to produce the final figured fabric pattern.
Beating up
The document discusses beating up in weaving, which is the final process that pushes the newly inserted weft yarn to the fell of the cloth to produce a compact fabric. It describes single and double beat-up mechanisms, the parts involved like the crankshaft and reed, and factors that influence beating force. Single beat-up uses a sley sword pivoted to a rocking shaft that pushes the reed forward during each pick, while double beat-up uses two arms connected to a crank to produce two beats per pick.
Weft knitting
Weft knitting is a method of knitting fabric where loops are formed horizontally from a single yarn. There are several types of weft knitted fabrics including plain knits, purl knits, interlock knits, and rib knits. Plain knits have different face and back sides while rib knits have the same appearance on both sides due to the use of two sets of needles forming alternating wales of stitches. Rib knits have excellent stretch widthwise and are heavier, warmer, and more expensive than plain knits. Weft knitting is used to produce various garments and textiles.

Some lessons of Weaving
Woven fabric is produced by interlacing warp threads that run lengthwise with weft threads that run across. The appearance and properties of woven fabric depend on yarn structure and fabric structure. There are four basic fabric parameters: thread count, yarn diameter, yarn bending, and weaving order. Weaving involves repeatedly raising warp yarns with harnesses to make a shed, inserting the weft through with a shuttle or rapier, and firmly beating it into place with a reed. Modern looms use rapier or projectile picking for higher speeds.
Fabric Structure and Design
This document discusses various types of fabric structures and weaves. It begins with an introduction to the main methods of fabric production - weaving, knitting, and non-woven. It then focuses on woven fabrics and provides details on the classification, representation, and basic elements of woven designs. The key woven structures discussed include plain weave, twill weave, and satin/sateen weave. For each weave type, the document explains the weave repeat, shift, characteristics, and examples. It also covers various types of draft plans and their uses for different woven structures.
Knitting needles
This document discusses three main types of knitting needles: bearded needles, latch needles, and compound needles. Bearded needles are the simplest and cheapest type, made from a single piece of metal with a fixed hook. Latch needles are more complex but self-acting, with a movable latch that opens and closes to form loops. Compound needles have a separate sliding element that works with an open hook to form loops without straining the yarn. The document provides details on the features, parts, advantages, and limitations of each needle type.
Jacquad shedding
This presentation summarizes the Jacquard shedding mechanism. It introduces the four presenters and provides background on the Jacquard loom, which can produce complex woven designs through individual control of warp threads. The presentation then covers the scope of Jacquard shedding, including its ability to control thousands of yarns and produce intricate designs. It also classifies different types of Jacquard looms based on their lifting capacity, design capacity, shed formation, and other features. Key aspects of the single lift Jacquard mechanism are explained. Advantages and disadvantages of the Jacquard loom conclude the presentation.
3rd ppt 2011.pptx
This document provides an introduction to knitting technology for a third year textile engineering program. It defines different types of textile fabrics and their processes, with a focus on knitted fabrics. Key terms related to knitting are defined, including courses, wales, stitch density, and knitting machines. The yarns used for knitting and development of knitting techniques are discussed. Comparison is made between weft and warp knitting as well as between knitting and weaving.
Honeycomb, Mock Leno, Huckaback weaves and Dobby Figure Designs
Miscellaneous Weaves:
Honeycomb, Mock Leno,
Huckaback, Dobby Figure Designs
Designs in which the ornament consists chiefly of small, detached spots or figures are employed in nearly all classes of yarn and yarn combinations, for dress fabrics, fancy vesting, and other textures in which elaborate figure ornamentation is not desired.
Winding
Winding is the process of transferring yarn from one package to another to facilitate further processing. There are several types of winding machines classified by the package wound, the winding method, or the drive type. The objectives of winding are to transfer yarn to a suitable package for weaving, remove faults from the yarn, clean and improve quality, and store the yarn. Common winding faults include yarn breakage, packages that are not properly shaped, twist variations, and packages that are dirty or contain hairiness.
Lappet weaving 151014002
This document discusses lappet weaving, a type of weaving that uses needles to superimpose small designs onto fabric. Lappet weaving is similar to embroidery and is done using a loom frame with needles that carry extra warp yarns. As the frame moves sideways across the fabric, it uses the needles to create rows of the pattern design. Lappet weaving can produce beautiful patterns and strong, durable fabrics as long as floats on the back of the fabric are kept short. However, it is a more expensive weaving technique and only a small amount of lappet fabric is produced currently.
Derivatives of single jersey structures
The document describes various derivatives of single jersey knit structures that can be produced using one set of needles. It provides details on structures like cross miss design, birds eye design, weft locknit design, mock rib design, single and double cross tuck designs, single and double Lacoste designs, simple crepe design, cellular blister design, twill effects, knit and tuck denim, zigzag, crow's foot, bubble knit, and mesh. These derivatives are created using different combinations of knit, miss, and tuck stitches and have repeating patterns that complete within a certain number of courses.
Mercerization
The document discusses the process of mercerizing cotton fabrics. Mercerizing involves treating cotton yarns or fabrics with a cold or hot solution of sodium hydroxide (caustic soda) under tension to improve properties like strength, luster, and dye affinity. Specifically, swelling the cotton fibers in the caustic soda solution changes their cross-sectional shape and increases luster when the tension is maintained during washing. There are different methods for mercerizing yarns, knits, and woven fabrics either as batches or continuously. The advantages of mercerizing include brighter dye colors, better color retention after washing, and increased strength, smoothness, and resistance to damage.
Dying machine
The document discusses different types of textile dyeing machines and their uses. It describes beam dyeing machines, which dye yarn or fabric wound onto a beam, maintaining even tension. Sample dyeing machines are used to dye small amounts of fiber, yarn or fabric efficiently. Yarn dyeing machines loosely wind yarn onto perforated tubes for uniform dye penetration. Knit fabrics are often dyed using jet dyeing machines, which allow for low water use, short dyeing times, and gentle fabric handling. Woven fabrics may be dyed using jigger or paddle batch machines.
Terry fabric
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.
Double lift and single cylinder
This document summarizes the double lift and single cylinder (DLSC) jacquard shedding system. It explains that in a DLSC jacquard, each yarn end is controlled by two hooks attached to a single needle, allowing the end to be lifted or lowered independently over two picks. It describes how two sets of knives move in opposite phases to control the two hooks and raise or lower each end. The DLSC jacquard produces a semi-open shed and allows the cylinder to turn only every other pick, unlike a single lift single cylinder jacquard.

Weaving Dataflows with Silk - ScalaMatsuri 2014, Tokyo
Silk is a framework for building dataflows in Scala. In Silk users write data processing code with collection operators (e.g., map, filter, reduce, join, etc.). Silk uses Scala Macros to construct a DAG of dataflows, nodes of which are annotated with variable names in the program. By using these variable names as markers in the DAG, Silk can support interruption and resume of dataflows and querying the intermediate data. By separating dataflow descriptions from its computation, Silk enables us to switch executors, called weavers, for in-memory or cluster computing without modifying the code. In this talk, we will show how Silk helps you run data-processing pipelines as you write the code.
Yarn formation
Fibre is any raw material that has a hair-like appearance or elongated shape due to its high ratio of length to thickness. A textile fibre must have suitable length, pliability, fineness and strength for conversion into yarns and fabrics. Yarn is a continuous strand composed of natural or manmade fibres or filaments used for weaving and knitting. Spinning is the process of converting fibres into yarn, which can be done through wet, dry or melt spinning depending on the fibre properties. Fibre properties like staple length, fineness and strength influence spinning and the properties of the final yarn.

1) A textile is a woven fabric made by interlacing warp and weft threads. Textiles now also refer to fibers, yarns and products made from them.
2) Weaving produces fabric by intersecting the warp (lengthwise) and weft (crosswise) threads. Yarn preparation involves winding yarn onto packages to facilitate weaving and removing faults.
3) Different types of fabrics include woven, knitted, non-woven and special fabrics. Proper yarn preparation and tension are important to produce good quality fabric during weaving.

Nonwoven FABRICS
This document provides an overview of nonwoven fabrics. It defines nonwoven fabrics as sheet or web structures bonded together without weaving or knitting, using mechanical, thermal or chemical processes. Some key points covered include:
- Common uses of nonwoven fabrics in household, industrial, and medical applications.
- Raw materials used like cotton, rayon, polyester and different fiber properties they provide.
- General production steps for nonwoven manufacturing including bonding techniques like needle punching, hydroentanglement, adhesive bonding and thermal bonding.
- Desired properties in bonding agents and different types of binders used.
Types of Yarn and Spinning
There are two main types of yarns: staple fiber yarn and filament yarn. Staple fiber yarn is made from short fibers and includes open end yarn and ring spun yarn. Filament yarn is made from continuous filaments and includes single filament and multifilament yarns. Rotor spinning and ring spinning are two processes for making yarn. Rotor spinning uses air and centrifugal force to twist fibers into yarn on a spinning rotor at high speeds. Ring spinning draws out roving, inserts twist, and winds yarn onto a bobbin simultaneously. Filament formation produces filament yarn by extruding liquid through spinneret holes and drying, twisting,

Process sequence of weaving
The document provides an overview of the process sequence for weaving. It begins with yarn from the spinning department which then undergoes processes like cone winding, warping, sizing, tying-in, drafting, and denting to prepare the warp threads. The warp is then mounted on the loom and undergoes weaving to produce grey fabric. Key steps in weaving include shedding, picking, and beating-up. The woven fabric then undergoes inspection, folding, and baling before delivery. The document outlines the various motions and essential parts of a loom needed to carry out this weaving process.
fabric manufacturing
Weaving is the process of interlacing warp and weft yarns at right angles to form fabric. Historically, shuttles were used to pass the weft yarn through alternating raised and lowered warp yarns (shedding), but now shuttleless looms using air, rapier or projectile mechanisms are more common. The key steps in weaving are warping to prepare parallel warp yarns, sizing the warp yarns, drawing the yarns into the loom, shedding to separate warp yarns, picking to pass the weft through, and beating-up to push the weft into place. Weaving involves the interlacing of the length-wise warp
Buhler Fiber To Yarn
This document describes the process of converting Supima cotton fibers into yarn. It begins with opening, blending, and cleaning cotton bales. The fibers then go through processes like carding, combing, and drawing to further clean and align them. This produces slivers and roving that are spun into yarn using ring spinning machines. The yarn is wound onto cones and packed for shipping to customers for knitting or weaving into fabrics. The document provides details on each step through pictures and explanations.

- 4. Ginning • Ginning is the separation of seed from seed cotton • Recovery of clean lint. The process requires a dryer, a gin saw or some other type of separation devices. • The clean lint is then compacted and tied with a bale wrap. • It is finally weighed and stored.
- 5. Opening and Cleaning of Raw Cotton • The object of this process is to blend cotton so as to obtain uniform raw material, remove leaf dirt and fresh, open up the fibres after they have been compressed in the bale • To deliver a clean uniform product in a suitable form to the nextstage.
- 6. Blow room • The blow room machinery performs function of opening hard pressed bales of cotton and cleaning the cotton of impurities
- 7. Carding • In carding, the lap is attenuated into a sliver (about 100 draft) • The fibres made parallel for the next stage.
- 8. Drawing • Drawing evens the sliver. • It attenuate the sliver to desired count • Doubling reduces mass CV
- 9. Roving • Roving further attenuates the sliver to above 7 draft. • It makes the sliver useful to make yarn
- 10. Spinning • There are two main types of spinning: ring spinning and open-end or break spinning. • In ring spinning the roving is further attenuated by roller drafting to the fineness of the yarn required, usually a draft of about 20 • and at the sametime twist is applied to give the yarn the necessary strength. • Full bobbins may be manually or automatically doffed.
- 11. Cone winding • Cone winding facilitates subsequent processing by rewinding yarn onto a large package • and removing faults.

- 23. Woven structures Twill weave Twill weave, the secondbasic weave, is characterized by diagonal lines running at angles varying between 15° and 75°. A twill weave is denoted by using numbers above and bellow a line (such as 2/1 twill which may be interpreted as two up and one down in the shedding sequence).
- 24. Woven structure Satin and Sateen weave Sateen weave is the third basic weave, in which the interlacing points are arranged in a similar way to twill weaves but without showing the twill line. The satin weave is warp face weave and the sateen is a filling face weave. Fig. Shows 5 ends (Harness) satin. In this case, the repeat is on 5 ends x 5 picks.
