We certify that this project was done by us under the supervision of Asit Ghosh, Assistant Professor, Department of Textile Engineering, Faculty of Engineering, Daffodil International University. This research titled "Analysis of different type of weft knitted fabric And Machine Efficiency" at Daffodil International University, November 2019. At first we thank the almighty God for enabling us to complete this project work successfully.
Asit Ghosh, Assistant Professor, Department of Textile Engineering, Daffodil International University, for his care and continuous guidance and supervision during our project work. Mahbubul Haque, Professor and Head of the Department of Textile Engineering at Daffodil International University for giving us the necessary permission to use the machine and materials at the beginning of the project. First, we collect some knitwear samples along with the necessary data needed to start our project work with effective analysis.
Our efforts have been to develop a reliable way so that we can easily visualize or predict the resulting material specification with required configuration. The theoretical as well as the practical knowledge that we have gathered from our classes and in industry help us to carry out our project with credit and for this we convey special thanks to our esteemed teachers.
CHAPTER ONE
INTRODUCTION
Our project is basically in the specifications of knitted fabrics and machinery related to the production of knitted fabrics. In the analysis of knitted fabric specifications, we considered wales per inch, course per inch, thread count, M/C diameter, fabric diameter, gauge, GSM, stitch length, fabric color, yarn type and many other things. The title of our project work is analysis of knitted fabric specifications, GSM, stitch length, thread count and machine efficiency.
For this reason, there are problems if an order arrives that has not been produced before. Our goal is to find out the easy process to decide on yarn count selection, machine diameter selection and machine gauge selection and machine efficiency. We strongly believe that by this process we can get a decision on yarn count, loop length, machine thickness and machine diameter for Single jersey, Rib, Interlock, Fleece, Terry fabric.

LITERATURE REVIEW
Cylinder: Cylinder is one of the main parts of knitting machine where all the needles are set
13. Automatic stop: If the knitting machine is defective, the automatic stop will stop the knitting machine automatically.
CHAPTER THREE
Data collection for facilitate understanding of the relation between dia, Gauge, GSM, SL, Yarn count of Normal Fleece machine: SL, Yarn count of Normal Fleece machine
Cylinder needles- The first two needles produce a knit loop and the last needle produces a slip loop. Dial needles - The first two needles produce a slip loop and the last needle produces a knit loop. Cylindrical needles: All odd-numbered needles produce knit loops, and even-numbered needles produce misloops.
Dial needles: All odd numbered needles produce miss loop and even numbered needles are. Cylindrical needles: All odd-numbered needles produce misloops, and even-numbered needles produce knit loops. Dial needles: All odd-numbered needles produce knit loops, and even-numbered needles produce slip loops.
3.6.6) Milano Rib: Milano Rib is a rib-based woven fabric. the appearance and characteristics of fabrics are related to the ratio of the course length of the two rows.
CHAPTER FOUR
From the above analysis it clearly shows that % of efficiency loss of tricot machine is maximum for taper change about 6.69% and clearance about 6.18%. This means that this knitting machine has stopped more time for changing and cleaning the cone. From knitting errors see the maximum efficiency loss for thread breakage and cone change is found. From the above analysis it clearly shows that the efficiency loss % of this single knitting machine is maximum for fabric discharge about 4.11% and yarn breakage about 2.3%. This means that this knitting machine has stopped more time for unloading the fabric and breaking the threads. From the view of knitting errors, the maximum efficiency loss is found for yarn breakage and taper change.
From the above analysis, it clearly indicates that the efficiency loss % of single jersey machine is maximum for unloading material about 4.25%, yarn breakage about 2.86% and cleaning about 2.78%. This means that this knitting machine has stopped more time to unload fabric, break yarn and clean. From knitting errors view, maximum efficiency loss is found for yarn breakage and taper change. shutdown Cleaning Cone change Power off.
From the above analysis, it is clear that the efficiency loss% of this single jersey machine is maximum for cone change of about 3.12%, yarn breakage of about 3.0% and cleaning of about 2.91%. That means this knitting machine has put more time into cone changing, yarn breaking and cleaning. From the point of view of knitting errors, maximum efficiency loss is found with yarn breakage and cone change. From the above analysis, it is clear that the efficiency loss% of this single jersey machine is maximum for cleaning about 5.73% and yarn breaking about 5.24%. That means this knitting machine has put more time into cleaning and yarn breakage.
From the above analysis, it is clear that the efficiency loss% of this single jersey machine is maximum for cleaning about 3.61% and yarn breaking about 3.12%. That means this knitting machine has put more time into cleaning and yarn breakage. From the above analysis, it is clear that the efficiency loss% of the single jersey machine is maximum for cleaning about 7.85%, yarn breakage about 7.23% and cone change 6.69%. That means this knitting machine has spent more time on cleaning, yarn breakage and cone modification. From the above analysis, it is clear that the efficiency loss% of this single jersey machine is maximum for yarn breakage of about 13.79% and cleaning of about 7.23%. That means this knitting machine has put more time into yarn breakage and cleaning.
From the above analysis, it clearly indicates that the efficiency loss % of this single jersey machine is maximum for yarn breaking about 12.89% and cleaning about 7.94%. This means that this knitting machine has more time stopped for yarn breaking and cleaning. From the above analysis, it clearly indicates that the efficiency loss % of this single jersey machine is maximum for cleaning about 8.26% and yarn breakage about 5.66%.
CHAPTER FIVE
CONCLUSION
Through the project work of "Analysis of Various Weft Knitted Fabrics and Machine Efficiency", we have gained a complete practical knowledge of knitted fabrics, its characteristics, machine setup, historical development, state of domestic knitted fabric manufacturing enterprises, types, raw material requirements, its manufacturing and processing procedure, parameters of manufacturing , processing and quality control. We are really lucky that we got the chance to do our project work in a specialized area of textile processing. We have also carried out almost all quality tests of knitwear in the test laboratory.
We believe that through this practical work and study, we have gained good technical knowledge about the knitwear production process. We believe that our achievements in project work will help us to face the challenges of our future life. Finally, we would like to thank everyone who helped us in the implementation of our project work.
