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.

Simplex machine. Roving, sliver
A roving frame produces rovings of cotton and synthetic fibers through a process of drafting, twisting, and winding. It attenuates sliver through multiple drafting zones to form rovings of the required count. A flyer inserts twist into the roving as it is wound onto bobbins. Modern roving frames can achieve higher production rates through increased flyer speeds up to 1400 rpm and delivery speeds up to 40 m/min. They also have improved drafting systems and flyer designs for better fiber control and a wider draft range.
Differents parts of Simplex Machine and their Functions
The fly frame takes the thicker draw sliver and drafts, twists, and winds it into a thinner roving package. It attenuates the sliver through multiple drafting rollers that increase in speed, which stretches and thins the material. A flyer inserts twist into the roving to hold the fibers together. The key components of the fly frame are the creel, drafting rollers, flyer, spindles, and winding components. Modern fly frames like the Toyoda FL-100 and FL-200 use servo motor systems for more precise control compared to earlier cone drive systems.
DIFFERENT TYPES OF DRAFTING SYSTEMS
Drafting is the creation of a drawing or other graphical representation of a building, mechanical device or other structure for the purposes of determining how the device should be created. Drafting is used as a part of the design and fabrication processes. Drafting can be done by hand or using specially designed computer programs and mechanical drawings.
Drafting arrangement is the most important part of the machine. It influences mainly evenness and strength The following points are therefore very important
carding

Warp stop motion
This document discusses warp stop motion, which is a mechanism that stops the loom immediately when a warp thread breaks during weaving. There are two main types: mechanical and electrical. The mechanical type uses drop wires and reciprocating bars to obstruct loom movement if a thread breaks. The electrical type uses drop wires to complete or break an electrical circuit, activating a solenoid that stops the loom. Both aim to prevent faults from occurring in the fabric if a thread breaks by halting the loom quickly.
Cotton Yarn Quality Depends on Mixing Strategy
Cotton is a natural fibre available easily and abundant quantity. It is a most suitable fibre for textile spinning & clothing due to it’s good spinnability & human friendly characteristics. As cotton is a natural fibre hence it’s properties also affected with several other factors which create variation in fibre properties, these variations also affect spinning processes & it’s products Quality in multi dimensions. Each fibre characteristic impact individually and collectively on spinning process or at ultimate product quality. Revolutionary changes observed in last two decade in the field of spinning machineries where processing speeds greatly increased to enhance production rate. Not only production rate of spinning machines increased but speeds of it’s downstream processes also increased simultaneously which requires better quality of yarn for smooth process and without any interruption to get the maximum efficiency. Hence now it is most important to co-relate fibre properties with respect to it’s consumer process competency. In this article we will discuss the different cotton properties and it’s impact on spinning process and product quality in present prospective and will try to minimize the impact of poor fibre properties on process or product Quality through better Mixing plan selection.
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.
Take up mechanism
The document provides information about take up motion in weaving looms. It discusses the objectives and classification of take up motion. It describes the mechanisms of 7-wheel and 5-wheel take up motions. The 7-wheel take up motion uses 7 gears to continuously wind fabric onto the cloth roller, while the 5-wheel uses 5 gears for an intermittent winding motion. Calculations are provided for determining picks per inch using the gear ratios and dimensions of each take up type.
Machine parameter of speed frame
The document discusses the key components and processes of a speed frame machine. It describes the functions of creeling, drafting, twisting, building, and winding processes to attenuate sliver and produce roving. The drafting system and its roller configuration is explained.

Tension is important for winding density and removing defects, and can be achieved through multiplicative, additive, disc, or compensation tension devices. The target audience is third year textile engineering students.
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.

Bdft ii, tmt, unit-i, loom & itz types
This document compares conventional looms to modern looms, focusing on shuttle looms, projectile looms, and rapier looms. Shuttle looms are the oldest type but are slow and noisy. Projectile looms insert weft using a bullet-like projectile and have advantages like higher speeds, less wear on threads, and ability to weave multiple fabrics at once. Rapier looms insert weft using rigid or flexible rapiers and gripper heads, allowing for high insertion rates but also potential for more yarn breaks if not properly tensioned. Modern looms like projectile and rapier looms offer improvements over conventional shuttle looms through technological refinements.
Fancy Spinning
The document summarizes different types of specialty yarns including Bobtex, chenille, slub, siro, and core spun yarns. It provides details on the production processes, properties, and end uses of each yarn type. The Bobtex process produces an integrated composite yarn using a core of filaments or multifilaments covered with staple fibers and a polymer layer. Chenille yarn has a fuzzy surface due to short cut pile yarns wrapped around a core. Slub yarn is produced with intentional thicker and thinner sections. Siro spinning combines spinning and twisting in one step to make a two-fold yarn. Core spinning covers a core yarn, typically filament,
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

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
