Knitting types
This document discusses various types of knitted fabrics. It begins by explaining that knitting involves interlocking loops of yarn or thread to form cloth or crafts. There are two main types of knitting: weft knitting uses horizontal yarn fed into needles, while warp knitting uses vertical yarn loops. Specific weft knits discussed include single jersey, purl, rib, and interlock stitches. Warp knits highlighted are tricot, raschel, and milanese. The document also briefly touches on technical textiles, seamless technology, float plating technology, 3D fabrics, and knitting machines used.
Yarn Manufacturing
Textile yarn manufacturing involves several key steps. Fibers are first opened and cleaned through blowroom and carding processes. Drawing further arranges fibers into parallel strands called slivers. Roving attenuates slivers and adds twist. Ring frames then spin roving into yarn using drafts and twist. Combing upgrades raw materials by removing short fibers. The processes work to arrange, draft, and twist fibers into consistent yarns for weaving or other uses.

Knitting
Knitting is a process of making fabric by interlocking loops of yarn. It can be done by hand or machine, and involves pulling loops of yarn through previous loops to form the fabric. There are two main types of knitting: weft knitting and warp knitting, which differ based on the direction the yarn moves during knitting. Weft knitting uses yarn that moves across the fabric, while warp knitting uses yarn that moves in the lengthwise direction of fabric formation. Knitted fabrics are used widely in apparel and technical textiles due to properties like stretchability, shape retention, and moisture absorption.
Weaving process
Shyamoli Textile Engineering College is affiliated with the University of Dhaka. Weaving involves interlacing two sets of threads at right angles to each other to form fabric - the warp runs longitudinally and the weft crosses it. The warping process transfers yarn from packages to a section beam, which must have uniform tension, no defects, and be smooth. Weaving requires three operations - shedding to separate warp threads into layers, picking to pass the weft through the shed, and beating-up to push the weft pick into the woven fabric.
Warp knitting
Warp knitting is a method of knitting where loops are formed vertically along the length of fabric from warp yarns. There are several types of warp knitting including tricot, raschel, and milanese knits. Tricot knits use compound needles and are used for fabrics like lingerie, loungewear, and uniforms. Raschel knits use latch needles and heavier yarns, producing more textured fabrics for applications like carpets, home textiles, and outerwear. Milanese knits form diagonal patterns and are often made from filament yarns into lightweight fabrics.

INTRODUCTION Knitting
Knitting is a process of fabric production that involves interlooping yarns to form a fabric or garment. It can be done by hand or machine, but the basic principle of pulling a new loop through an old loop remains the same. Knitting originated over 1000 years ago and has since evolved from finger knitting to include machines with needles. Key terms in knitting include wales (vertical columns), courses (horizontal rows), stitch density (number of loops per area), and stitch length. Knitting allows for garment production and creates fabrics that are more comfortable, crease-resistant, and extensible than woven fabrics.
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.
Knitted fabric
Knitted fabrics are made from interlocking loops of yarn. There are two main types of knitting: weft knits and warp knits. In weft knitting, loops are linked across the width, while in warp knitting loops are linked vertically. Weft knits can be made by hand or machine and have stretch and retain heat, but can lose shape. Warp knits are made quickly by machine, are elastic but hold their shape, and lie flat when cut.
Fancy weaves
The document discusses various types of decorative woven fabrics including plain weave, twill weave, fancy weaves, pile fabrics, leno weave, crepe weave, double cloth weaves, and slack tension weaves. It provides examples of each type of weave and describes their distinguishing characteristics and production methods. Complex weaves like jacquard, brocade, and damask use additional warp or filling yarns to create intricate patterns in the fabric structure.
KNITTING
This document discusses different types of weft knitting techniques. It describes the basic process of weft knitting where loops are formed across the width of fabric using a single thread. The main types discussed are plain/single jersey, purl, rib, and interlock fabrics. For each type, it provides details on how they are knitted, their properties and characteristics.

It provides details on the construction, properties, end uses and raw materials for different weaves and knitting stitches. It also lists and describes common defects in weaving like bias fabric, bowed fabric. Defects in knitting, dyeing, printing and finishing are also outlined.
Yarn production process/ Spinning process
This document summarizes the process of yarn manufacturing from fibers through spinning. It describes how fibers are opened, cleaned and formed into laps in the blowroom. The laps then go through carding to be further cleaned and formed into slivers. Combing is used to straighten and parallelize fibers. Drawing drafts and blends slivers. Roving/Simplex frames draft and add twist to form rovings. Ring frames further draft and twist rovings to produce yarn, which is then wound onto bobbins. The key steps are blowroom, carding, combing or drawing, roving/Simplex frame, and ring frame spinning.
Types of fabrics
This document provides information on various types of fabrics, including poplin, cambric, voile, canvas, brocade, crepe, georgette, chiffon, and others. It describes the materials, weaves, historical uses, and distinguishing characteristics of each fabric type. Key details are given on fabrics such as poplin traditionally being made of silk and worsted yarn, cambric originating from Cambrai, France, voile meaning veil in French, and brocade being woven with an ornamental supplementary weft for pattern. The document serves as an informative reference on the properties of different textile fabrics.
Weft Knitting
In weft knitting, the loops are formed across width of the fabric Each weft thread is fed , more or less at right angles to the direction in which the fabric is produced.Weft-knit fabrics may also be knit with multiple yarns, usually to produce interesting color patterns.
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.
Weaving
This document discusses various aspects of ring spun yarn measurement and production. It begins by explaining that yarn size is typically measured through linear density or count systems. It then provides details on direct and indirect count calculation methods as well as conversions between different systems. The document also covers topics like folded and plied yarn calculations, the formation of different fabrics like weaving and knitting, and requirements for high quality yarn production. Key steps in the production process like winding, warping, sizing, drawing-in and weaving are outlined. Different weaving machine types based on the weft insertion method are also summarized.
Weaving
This document discusses the development of looms from primitive hand looms to modern automated looms. It outlines the key stages of development including the fly shuttle loom, power looms, semi-automatic looms, and modern shuttle-less looms. The basic mechanisms and motions of weaving are described, including primary, secondary, and tertiary motions. Different parts of a loom and their functions are also summarized.
Interlock fabrics
Interlock fabrics are a variation of rib knit construction where both sides of the fabric look identical due to a double knit construction. Interlock fabrics have identical appearances on the front and rear surfaces, making them double-sided. They are tightly knitted, giving a smooth surface and firm feel. Interlock fabrics have advanced dimensional stability and can stretch more in the lengthwise direction than widthwise. They provide better heat insulation than single knit fabrics due to an insulating layer of air between the front and rear surfaces.
FABRIC STRUCTURE
1) The document discusses different basic weaves including plain weave, twill weave, and satin weave. It explains how each weave is constructed and provides examples of fabrics made with each weave type.
2) Graph paper is used to represent weaves, with squares indicating where warp and weft threads interlace. Different graph paper sizes are used depending on the thread count of the fabric.
3) Derivatives and variations of the basic weaves are also covered, such as basket weave, rib weave, herringbone twill, and diamond and diaper twill designs. The uses of twill weave for different fabric types is mentioned.
Braid fabrics
Braiding is a simple form of narrow fabric construction. A braid is a rope like thing, which is made by interweaving three or more stands, strips, or lengths in a diagonally overlapping pattern. They have good elongation characteristics and are very pliable, curving around edges nicely.
Braids are divided into two types :
1. Flat braids, in the form of strips or narrow flat
tapes.
2. Round braids, tubular in form, which may be
hollow or have a center core of some material.
Braiding are produced from any of the textile fibers (cotton, jute, nylon, glass fiber, rubber .................etc), as well as from metal threads, tinsel, straw, wire or leather.
The traditional circular braiding machine contains a series of bobbins of yarn mounted on a moving track at the bottom of the machine. The braid is produced as the bobbins move in and out around the base of the machine ,much as Maypole dancer do. Interweaving yarns by braiding produces a flexible fabric; the fabric can be stretched in one direction, but it contracts in the other.
Braided fabrics braiding is more significant for Industrial fabrics than consumer textiles. Braiding is one of the major fabrication methods for composite reinforcement structures , with increasing application of electrical wires and cables, harnesses , hopes, Industrial belts and surgical sutures. This principle of fabric construction is used for making shaped articles , such as straw hats and small rugs ;narrow fabrics , such as ribbons and braids for millinery and accessory dress materials; cords and tapes, such as fish lines, show laces, wicks, parachute cords and structural components for other industrial products.

Draw Frame lecture 1.pptx
The draw frame is a machine that combines and draws out slivers of textile fibers to prepare them for spinning. It performs the process of drawing, which elongates and blends slivers by passing them through pairs of rollers that increase in speed. This straightens, levels, and aligns the fibers for further processing. The draw frame improves fiber uniformity and removes dirt and shortcomings from previous processing steps to produce slivers suitable for the next stage of spinning.
Weaving1
The document provides details about the weaving process from warping to final folding of the woven fabric or towel. It involves key steps like warping, sizing, drawing-in, looming, and folding. Warping involves winding yarn parallel onto beams. Sizing adds size to strengthen the yarn. Drawing-in threads the yarn through heddles and reed according to the weave pattern. Looming uses looms like Sulzer or air jet to weave the warp and weft yarns. Folding inspects and packs the final woven product.

Rotor spinning
This document compares ring spinning and rotor spinning methods of yarn formation. It discusses that rotor spinning is a more recent method that omits the step of forming a roving. In rotor spinning, fibers are fed into a rotary beater and deposited onto the sides of a rotating disc called a rotor, where they are twisted without requiring package rotation. Rotor spinning allows for higher twisting speeds with lower power usage compared to ring spinning. It provides characteristics like higher productivity, larger sliver/package sizes, less power consumption, and more automation/flexibility. The document provides details on the parts of a rotor spinning machine and compares various parameters of ring-spun and rotor-spun yarns.
Direct warping
This presentation discusses direct warping, which is a high-speed warping process used to make common fabrics in large quantities from single yarns. The key components of a direct warping machine are the creel, expanding comb, pressure roller, and beam. Direct warping is not suitable for producing stripe effects because it does not allow for warp patterning. Improvements to direct warping include better tension uniformity, larger bobbins and beams, and higher accuracy in measuring. Direct warping is compared to sectional warping, with direct warping having higher production but requiring larger amounts of yarn.

Basics of Fabric Manufacturing
The document provides information about the basics of fabric manufacturing processes. It discusses the key steps which are:
1) Yarn production from the spinning department which includes processes like winding, creeling, and warping. Warping can be done using direct/beam warping or indirect/sectional warping methods.
2) Sizing of the warp yarns is then carried out to prepare them for weaving.
3) The warp yarns are threaded through the heddles and reed during loom preparation before weaving begins.
4) Weaving is the process that interlaces the warp and weft yarns to produce fabric. The fabric then undergoes inspection, folding
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
Warping and details
This document discusses warping, which is the process of winding warp yarn parallel onto a warp beam in textile manufacturing. It defines warping and describes the requirements, such as uniform spacing and tension of ends. It discusses different types of warping like direct/beam warping and sectional warping. Direct warping is described as a high-speed process using a simple beam suitable for single-color fabrics. The components and working principle of a direct warping machine are explained. Advantages like high production and disadvantages like unsuitability for stripe fabrics are provided. Calculations for determining yarn length per beam are shown. Common warping faults and how to improve the beam warping process are also covered.
Different types of loom
Loom is machine or device which is used to produce woven fabric. It is the central point of whole process of cloth production. In other word, a loom is a mechanism or tool used for weaving yarn and thread into textiles. Looms vary in a wide assortment of sizes. They come in huge free standing hand looms, tiny hand-held frames, to vast automatic mechanical tools. A loom can as well pertain to an electric line construction like that of a wiring loom. The main task of looms is to clutch the twist threads under pressure to enable the progress of interweaving of the woof strands. The loom's system and exact form can differ to some extent; however it still performs the basic application.

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
