Ring frame
INTRODUCTION
The ring spinning will continue to be the most widely used form of spinning machine in the near future, because it exhibits significant advantages in comparison with the new spinning processes.
Following are the advantages of ring spinning frame
• It is universally applicable, i.e. any material can be spun to any required count
• It delivers a material with optimum characteristics, especially with regard to structure and strength.
• It is simple and easy to master
• The know-how is well established and accessible for everyone
Carding note
1. Carding is the process of reducing tufts of entangled fibers into a filmy web of individual fibers using machines called cards. There are three main types of cards used for cotton, wool, and man-made fibers.
2. The carding process opens fibers, removes impurities, disentangles neps, blends fibers, orients fibers, and forms slivers for further processing. It transforms a fiber batt into a uniform web of individual fibers.
3. Fiber batts are fed to the carding machine using either a lap feed system or a flock feed system. The chute feed system aims to feed a fiber sheet of uniform packing density and linear density.
Rapier Loom
This document discusses the rapier loom and rapier weaving. It begins by defining a rapier loom as one that uses a rapier to pull the weft yarn across the loom. It can use a single or double rapier system. It then describes the key components and functioning of single and double rigid and flexible rapier systems. It also discusses different weft insertion principles like Dewas and Gabler systems as well as rapier drives, features of modern rapier looms, selvedge formation, weft insertion rates, and equations for calculating weaving production rates.
Blowroom
The document discusses the key processes that take place in the blowroom of a yarn production facility. These include opening bales of fiber, cleaning the fiber through pre-cleaning and fine cleaning, removing dust, blending different fiber types, and evenly feeding the prepared fiber to the carding process. The goal of blowroom processes is to prepare fibers for subsequent processing while minimizing fiber loss and maintaining fiber quality.
Roving
The document discusses the roving frame machine, which comes after the draw frame in the spinning process. The roving frame drafts sliver from draw frame cans into a thin roving strand and applies a light twist. It operates by drafting the sliver, guiding it through the flyer to apply twist, and winding the roved strand onto bobbins. While complicated, the roving frame produces packages of roving suitable for input to the ring frame. Efforts to eliminate this step have not succeeded due to the high drafts required in ring frames.
Woven Shedding Mechanisms
This document discusses different types of shedding mechanisms used in looms: crank, tappet, dobby, and jacquard. It explains how each works and their features. Crank is the simplest but can only produce plain weaves. Tappet controls 2-8 heald frames for simple weaves. Dobby controls more frames for medium complexity weaves. Jacquard is the most complex but can produce all fabric types by controlling thousands of heald frames individually. The timing of shed opening, early vs late, also affects weaving properties.
Important of textile testing
Textile testing is an important part of the textile production process. It involves determining various properties of fibers, yarns, and fabrics to ensure quality standards are met. The objectives of textile testing include selecting raw materials, controlling manufacturing processes, ensuring quality of finished products, and facilitating research and product development. There are different types of textile testing for fibers, yarns, woven fabrics, knitted fabrics, and nonwoven fabrics. Test methods are established by various standards organizations and influence factors like sampling methods, atmospheric conditions, equipment used, and technician skill.

Compact Spinning System
The compact spinning is a process where fiber strand drawn by drafting system is condensed before twisting it.Following methods are used by machine manufacturers to condense the fiber strand.
1. Aerodynamic condensing.
2. Mechanical condensing.
3. Magnetic condensing.
Compact spinning has a promising future because of the higher production and improved quality of compact yarns
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.
Warping
1. Warping involves winding warp yarns from multiple packages onto a common beam. There are different types of warping including direct/beam warping and pattern/sectional warping.
2. Direct warping is used to produce warp beams for solid color fabrics directly from packages to the beam. Sectional warping is slower but used for short runs or complex patterns by making sections sequentially.
3. A warping machine has a creel to hold packages, a headstock to guide and tension yarns, and a control device. It measures and winds yarns uniformly to produce a warp beam meeting quality requirements.
Rapier loom
The document discusses the rapier loom, a type of shuttleless weaving loom. A rapier loom uses finger-like carriers called rapiers to pull the weft yarn across the loom between the warp yarns. There are two main types - single rigid rapier looms, which use one long rapier across the full width, and double rigid rapier looms, which use two rapiers entering from opposite sides to transfer the weft yarn. Rapier looms can operate at high speeds up to 1300 meters of weft per minute. They are flexible and can weave a wide range of fabrics from light to heavy weights.
Yarn twist
The document discusses yarn twist, which is the spiral arrangement of fibers that binds them together and contributes to yarn strength. It defines twist, describes different types of twist including real and false twist. It also discusses factors that affect twist, methods of measuring and expressing twist, and the effects of twist on yarn and fabric properties such as handle, moisture absorption, and wearing properties. High twist results in a harder handle, better abrasion resistance, and lower moisture absorption, while low twist produces a softer feel but weaker yarn.
Projectile weaving
The document summarizes projectile weaving, which uses gripper projectiles to insert weft threads into warp threads. Key points:
- Projectile weaving machines were invented in 1924 and introduced commercially in 1953. They use small, bullet-like projectiles to insert weft threads at high speeds up to 1500 picks per minute.
- Projectile looms produce fabrics with good quality at high efficiency and low energy use. They can weave a wide variety of yarns from fine to coarse.
- The projectile is propelled through the warp shed using stored energy from a twisted metal torsion bar, allowing very high insertion speeds. It grips the weft securely and deposits it without

For take-up motions, it provides details on negative take-up, five-wheel take-up, seven-wheel take-up, and Shirley take-up motions. For let-off motions, it discusses negative and positive let-off systems. It also explains warp protecting, warp stop, and weft stop motions that are used to stop the loom in case of issues like shuttle trapping or yarn breaks.
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.
Yarn unevenness and its empact on quality
This document discusses yarn unevenness, its causes, measurement, and impact on quality. Yarn unevenness refers to variations in yarn thickness along its length. It is influenced by raw material variations and spinning process irregularities. Unevenness is measured using the irregularity percentage and coefficient of variation. Higher unevenness can reduce yarn strength, impact fabric appearance with defects, and lower productivity. Careful control of the spinning process is needed to minimize unevenness and maximize quality.
FRICTION SPINNING TECHNOLOGY, (M.S)
Dref system is Dref 3000
which was introduced in
2003.It has higher
production capacity than
Dref 2000.
This document discusses friction spinning, also known as Dref spinning. It is a textile technology suitable for spinning coarse yarn counts and technical core-wrapped yarns. Dref yarns have low tensile strength, making them suitable for blankets, mops, and filters. The technology was developed in 1975 and allows yarns like rayon and Kevlar to be spun. Friction spinning uses two friction surfaces to roll fibers into yarn with very little tension applied. This makes it more productive than other spinning methods like ring and rotor spinning. Developments
Draw frame (1)
The document discusses the draw frame process and its components. A draw frame is used to improve the quality and evenness of carded sliver by straightening fibers, increasing parallelization and reducing weight variations. It works by drafting (attenuating) multiple input slivers through roller pairs to produce a single, more uniform output sliver. Key components include the drafting arrangement, which applies different levels of draft, and an auto-leveling system to compensate for input weight variations and maintain consistent output. The document provides details on draw frame components, working principles, objectives and the influence of drafting and doubling on sliver quality.
Autoconer
The document describes an autoconer machinery used for winding yarn into cones. The autoconer is a Savio Orion model from 2005 with 60 cones. It has a drum speed of 1300 rpm, cone weights of 2-3 kg full and 30-35 g empty, and a magazine creel capacity of 6 ring tubes. The autoconer has features like a pneumatic disc tensioner, splicer, and electronic yarn clearer. It can produce 800-1200 kg of cones per shift with up to 95% efficiency.
textile finishing
The document discusses various textile finishing processes. It describes finishing as a process that improves the look, performance, hand and feel of textiles. Some key finishing processes covered include damping, drying methods like cylinder drying and stenter drying, calendaring, and crepe effects. It also discusses shrinkage prevention in cotton and different types of finishes like temporary, permanent and semi-permanent.
Yarn Geometry
This presentation discusses yarn geometry and various types of yarns. It defines textiles and yarn, and classifies yarns into continuous filament, staple, core spun, novelty, stretch, and high bulk yarns. It describes the properties, structures, and manufacturing processes of these different yarns. The presentation also covers yarn designation, ideal yarn properties, fiber packing in yarns, optimum twist factor, twist contraction, and the basic geometry of twisted yarns.
Milling of wool
Milling is a process that felts wool fabrics to make them thicker, fuller, and more uniform. It involves treating wool fabrics with moisture, heat, and pressure in a milling machine. There are several types of milling depending on the chemicals used, such as alkaline milling using sodium carbonate, soap milling using soap solutions, and acid milling using diluted sulfuric acid. The objective is to felt the wool fibers together to condense and shrink the fabric while also making the weave less visible. Milling improves the strength, handle, and appearance of the wool fabric.
Determination of fiber length by comb sorter diagram
This document describes an experiment to determine cotton fiber length using a Shirley comb sorter. Key steps include:
1) Straightening and arranging cotton fibers within the comb sorter.
2) Removing fiber groups one by one and laying them out to create a fiber length distribution curve.
3) Analyzing the curve to determine fiber length parameters like maximum, upper quartile, effective, and modal lengths.
4) Calculating American and Indian staple fiber lengths as percentages of the effective length.
Conventional loom and modern loom
This presentation compares conventional and modern looms. Conventional looms operate more slowly with lower production capacity, while modern looms operate faster with higher output. Conventional looms are manually operated, while modern looms use electric power. Modern looms allow for more design variety and improved safety systems compared to conventional looms. Specific modern loom types discussed include rapier, air jet, water jet, and projectile looms, which utilize different automated processes for inserting the weft through the warp shed.
Beat-up Mechanism of Fabric
The beating-up mechanism is used in weaving to push the newly inserted weft pick to the fell of the cloth. It consists of a reed fixed to a sley that is given a quick motion towards the fell by cranks connected to a crankshaft. The main parts include the crankshaft, crank, connecting arm, reed cap, reed, sley race, sley, and sleysword. The sley receives a reciprocating motion from the rotating crankshaft via the crank and connecting arm, which pushes the reed and new weft pick to the fell. Some looms use a double beating-up mechanism with two arms to give two blows per

Accident detection system project report.pdf
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdf
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days
Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
