Sabbir This paper presents the concepts of a Textile Yarn Unwinding and Winding System for application in the textile industry. Considering that textile industry market is constantly growing, this work aims to develop a system of unwinding and winding of textile yarn that will later be applied to a system of verificationof the quality of the textile yarn through image processing. The article first presents the methodology used for prototype development. It then presents the relevant concepts and mathematical model for the development of a system that allows unwinding and winding the textile yarn as well as adequate yarn tension control. feasibility is discussed, and the added value of this prototype is highlighted.

Hafizur We worked with knit and woven fabrics where we collected data on their production faults and analyzed it, through which we were able to find out the percentage of those faults. From this data analysis we found Knit fabric F/Y (Fly Yarn) = 13,U/T (Uneven Tension) = 0 ,O/L (Oil Line) =4,O/S = (Oil Spot) = 20,N/B = (Needle Break) = 4,T/T = (Thick and Thin) = 0,B/S = (Black Spot) = 0,L/C = (Lycra cut) = 43,Loop = 63 Woven ( Denim ) fabric Knot-52.58%,Slub in Weft-17.53%,Loose End-16.49%,Broken Pick- 3.09%,TightEnd-3.09%,Starting-2.06%,Course Pick-2.06%,Double Pick-2.06%Miss Pick_1.03% Thesis 2025-01-23T00:00:00Z http://dspace.daffodilvarsity.edu.bd:8080/handle/123456789/17305 Study on Sample Development Procedure for Knit Items Datta, Joy The Ready-Made Garment (RMG) sector is the cornerstone of Bangladesh's economy and a key driver of its development. In the Ready-Made Garment (RMG) sector, the sample creation process is essential to achieving customer expectations, guaranteeing product quality, and expediting manufacturing. Receiving the buyer's technical package, often known as the "tech pack," which includes design specifications, measurements, fabric specifics, and trims, usually marks the start of this phase. The initial pattern must be prepared initially, and then the necessary fabric and trims must be sourced and developed. The first development sample or prototype is made once the materials are available in order to assess the precision of the construction and the viability ofthe design.To guarantee appropriate size and comfort, a fitsample is created after analyzing and taking into account customer input. A pre-production (PP) sample is created after approval to ensure that bulk production will satisfy all requirements. Indepth quality inspections and buyer communication are part of every step. A seal sample, which acts as the standard reference for bulk manufacture, is produced at the end of the procedure. I gained understanding about the sample development process during my internship. The thesis report includes instructions on how to begin and complete the sample development process.

This study explores the dyeing of cellulosic materials, specifically cotton and jute, using a natural dye extracted from onion skins. The researchinvestigates the effects of different mordants, including Lemon juice and Tanic acid, on dye uptake, colorfastness, and overall dyeing properties. Experimental results indicate significant variations in color intensity and shade, influenced by the type and concentration of mordant used. UV-Vis spectroscopy and colorimetric analysis were employed to quantify dye absorption and assess color changes over time. The findings contribute to understanding the feasibility and sustainability of onion skin dyeing in textile applications, highlighting its potential as an alternative to synthetic dyes in eco- conscious practices.
