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.

Sizing is the process of giving a protective coating on the warp yarn to minimize yarn breakage during weaving.
Sizing is the most important operation in preparing warp yarn for weaving especially with cotton yarn. The smallest error in sizing process may be very harmful. This may increase warp breakage rate on the looms and consequently reduce weaving production and quality. Therefore sizing is termed as the “Heart of Weaving”.

This is an internee report on SINHA ROTOR SPINNING LIMITED. It is done by Shahadat Hossain, K. M. Mamunur Rashid, Sadikur Rahman Shawpon, Ashfaqur Rahman, We are from Department of Yarn Manufacturing, Bangladesh University of Textiles. I would be happy is anyone get any benefit from this.
: Blow room consists a number of machines used on succession to open and clean the cotton fiber. About 40% to 70% trash is removed in blow-room section
The blow room is must needed type section of a spinning factory where different type of works are done like fibre opening, cleaning and some other further acts which is needed to boost up the yarn quality
VDQ pulley (Variable Dia for Quality Pulley): It is a very important part of the machine. It controls the quality of the product. Altering the position of the tension pulley changes the G.S.M. of the fabric.

Northern Fashion Ltd. is a state-of-the-art Knitting, Dyeing – Finishing & Garment Manufacturing
factory. The project has been a setting up of a 100% export oriented composite knit
garment unit. The project has been designed to fulfill the present world market demand for
producing most value added fabrics. The project is equipped with open width finishing line.
This helps saving all types of fabrics consumption. Also the quality of fabrics is improved
tremendously. The machinery of the project is Brand new and has been imported from
abroad. The project has been started its commercial operation in the mid of 2007.
Industrial training is considered as one of the most essential part of engineering and
technical education. This training is included in our graduation program to introduce us
with the practical implementation of the technology that we have studied in our courses.
So, it is very helpful, lays the milestone for starting the carrier for fresh textile graduates
and helps to gain self-confidence and discover one’s own ability.
For any technical education, practical experience is equally necessary in association with
the theoretical knowledge. The industrial attachment is the most effective way to achieve
this practical experience. It provides sufficient practical knowledge about production
management, worker’s productivity, evaluation, work study, efficiency, industrial
management, production planning & control, inventory control, purchasing, utilities and
maintenance of machinery and their operation techniques etc. Like other engineering
fields, industrial attachment is also necessary for textile engineering.
Authors got an opportunity to complete 8 weeks long industrial training and they were
sent to Mosharaf Composite Textile Mills Ltd. They have done their training by gathering
information about various dept. in that mill. On the basis of that training the following
report has been prepared.
An intro of This Industry:
M/S Golden Crown Enterprises Int’l Ltd, Hong Kong, an umbrella organization, has started its operation in the field of processing in Dhaka Export Processing Zone(DEPZ), Bangladesh under incorporation in the name of “South China Bleaching & Dyeing Factory Ltd” and has been meeting the growing demand of 100% cotton/lycra fabric in Bangladesh Readymade Garment sector largely.
South China Bleaching & Dyeing Factory Ltd was registered on 14th February 1996 and commenced first commercial operation in July. 1998.
South China group is a rapidly growing multinational organization in Bangladesh. Over a long time being in business in Bangladesh as a pioneer, the organization has earned a solid reputation both locally & globally in Textile & Apparel sector.
The state-of-the-art textile machinery imported from Germany, Italy, USA and installed under the direct supervision of experts of supplier companies has developed an inbuilt means for optimum productivity with superior quality.
While South China remains a 100% export oriented organization, the company vision is to uplift Bangladesh globally in the textile sector.
Yarn printing is also known as “Space Dyeing”. Although the printing of yarns for true patterned effects proved very difficult tom control, the random space-dyed effects that can be more readily attained by a variety of yarn-printing methods have continued to be popular. The patent literature abounds with systems for producing colored flecked effects on yarns but the two most successful methods entail either warp printing or color application to a tubular knitted ‘sock’. The essential process sequence begins with dye liquor application, followed by steam fixation, washing-off and drying .

An Approach to Detecting Writing Styles Based on Clustering Techniquesambekarshweta25
An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap
-Shweta Ambekar
-Harshit Singh
-Nakul Sharma (Assistant Professor)
Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.
