Abstract: The main concern of this project work was to increase the wash fastness value of whitening fabric. In this project work the cotton fabric was treated in three different methods using synthetic optical brightening agent, Cationic Pretreatment of cotton fabric and application of green resource (vinegar and Lemon Juice) as alternative of synthetic agent. Six different concentrations (0.5-3%) of synthetic Optical brightening agent were used for assessment of wash fastness values but experimental data showed the concentrations have not visible influence to increase the fastness value rather than it decreases the wash fastness value after certain limit .On the other hand, the effect of cationic modification on cotton fabric was noticeable. The cationization of cotton fabric was performed at 60°C and..........

Abstract: Environmental aspects have been drawing extra space in all scholarly attempts of sustainable development as it's the only way forward to ensure sustainability in supply chain strategy at present global context. Conservation of natural resources, mainly water savings captured the prime attention of ecological concern for manufacturing entities; especially for industries like Textile and Readymade garment industry where plenty of water is used on daily basis. Textile processing is one of the largest and oldest industries worldwide and responsible for substantial resource consumption and pollution. This paper presents an approach towards environmental sustainability through adopting measures to conserve the water resource in the clothing industry.

Key Words: Conservation, Water resource, Sustainability, Textile and Apparel sector.

Abstract: After defining, dual prime numbers will be presented: Bölcsföldi prime numbers from 23 to 33333333223, Birkás prime numbers from 227 to 77772727777, Bölcsföldi-Balogh prime numbers from 353 to 53333335333, Bölcsföldi- Madar prime numbers from 557 to 57775777757 . How many dual prime numbers are there in the interval (10p-1, 10p) (where p is a prime number)? On the one hand, it has been counted by computer at least to 13 digits. On the other hand, the function (1) gives the approximate number of dual prime numbers in the interval (10p-1,10p). Near-proof reasonig has emerged from the conformity of Mills' prime numbers with dual prime numbers. The sets of dual prime numbers are probably infinite..

Abstract: In this study variations of knitted fabrics properties due to different yarn count was analyzed. Here weft knitted fabrics like single jersey were used. Yarn count and GSM of fabric has great impact on fabric properties. Aim of this project is to find out the convenient strategies to choose yarn count selection, GSM selection to get the desired qualities in the single jersey grey fabrics. In this research, Knit fabrics( made from 100% cotton yarn and blended yarn ) having different GSM were tested where 26 Ne,30 Ne 100% cotton yarns and 26 Ne blended yarns were used for manufacturing single jersey fabrics.

Key words: Fibre, Yarn, GSM, Yarn count, Stiffness, Tear strength.
