Article
Education in India, especially the Engineering Education is facing a lot of disinterest and disruptions. Further, the onset of Covid-19 pandemic has greatly affected the quality of education and revolutionized the entire method of teaching, learning, assessment and examination system in our nation. For the last one year, there is an almost absence...

Innovation is the creation of a new product or process. Innovation in engineering education means creation of a new spectrum of learning through improved or new methods, process and educational tools. Innovation is the heart of engineering for creating new designs, objects, products, and process from time to time. Hence understanding about the impo...
Article
The tensile behavior of Ring spun, Rotor spun, Air-jet spun and DREF-3 Friction spun yarns has been investigated at high strain rates and different gauge lengths. It is observed that the increase in gauge length from 150 mm to 500 mm decreases continually the yarn tenacity, breaking extension, but increases the breaking work and the modulus. The ro...
Article
The longevity of any garment depends on the seam parameters and fabric quality. In the present work, the quality of fabric samples was controlled, now the garment longevity depends on the seam parameters like various factors such as seam strength, seam slippage, seam puckering and yarn severance. In the present work, fabrics of different blend prop...
Article
This article deals with development and characterization of cotton and organic cotton flat knit bandages for wound healing. Bioploymers such as chitosan–sodium alginate, sodium–calcium alginate, and their mixtures were coated on the bandage and subjected to Fourier transform–infrared and scanning electron microscope analysis. Bacteria present in in...
Article
The present work deals with the development and characterisation of cotton and organic cotton based bandage using 40s Ne yarn. The physical properties such as areal density, air permeability and stiffness of fabrics have been measured. Chitosan-sodium alginate polymer, calcium-sodium alginate polymer and their mixture have been coated separately on...
Article
For the present work, polylactic acid yarn (140 denier) was used for the production of bandage. The physical properties of fabric were measured. Chitosan–sodium alginate, calcium alginate–sodium alginate polymer and their blends were coated separately on the bandage to incorporate wound healing, haemostatic, easy removal, biocompatibility and antib...
Article
Absorbent disposable products, such as diapers and sanitary napkins, are mostly one-time use items and designed to absorb and retain body fluids and solid waste. The present research work deals with the development and characterization of baby diapers made from four different fibrous compositions namely, pure bamboo, pure cotton, bamboo/cotton (70/...
Article
The bamboo yarn of Ne 40s was used for the preparation of the Gauze fabric. The physical properties such as areal density and stiffness of fabrics were measured. The fabric was then scoured and bleached as per the standard procedure using distilled water. Chitosan-sodium alginate, Calcium-sodium alginate polymer and their mixture were coated separa...
Article
This paper reports study on the development and characterization of baby diapers made from four different fibrous compositions, namely pure bamboo, pure organic cotton, bamboo/organic cotton (70/30), and bamboo/organic cotton (50/50). Antibacterial activity tests have been carried out on baby diapers against S aureus and E coli. Superabsorbent poly...
Article
Textile technologists have already recognized the role of fibre friction in various textile processes. Attempts have been made to develop a novel instrument system to quantify fibre friction and relate it with fibre processing, yarn quality and ultimately, the fabric handle. In this context, the current paper presents research work carried out in d...
Article
The manufacture of yarn usually involves conversion of staple fibers and filaments into a continuous assembly. Yarns that are produced with special characteristics and effects is made by recent innovations in the area of yarn manufacture. These innovations now focus on alternate methods of twisting the strand of fibers and forming the yarn at high...
Article
The influence of process variables on characteristics of modal siro-spun yarns has been studied using Box-Behnken response surface design. The characteristics of these yarns have been evaluated and compared with those of equivalent double-rove spun yarns. It is observed that the increase in strand spacing from 6 mm to 10 mm increases the unevenness...
Article
DREF 2000 and DREF 3000 models are the new additions to the DREF class of friction spinners. The DREF 3000 friction spinning machine works on the principle of DREF 3 friction spinner and spins elastomeric-core yarns along with speciality yarns in the count range of 33-590 tex. The DREF 2000 friction spinning machine uses DREF system with a rotating...
Article
Ring-spun yarns of different counts and fibrous materials have been studied for irregularity and imperfections. The irregularity-length equations have been developed using five different cut lengths (10, 100, 1000, 10000, and 100000 mm) to deduce irregularity-length indices (m and a). The values of 'm' and 'a' for all the yarns are found to be -0.2...
Article
The influence of frictional characteristics of core and sheath, core-sheath ratio, and spinning drums' speed on the tensile characteristics of DREF-3 friction-spun yams has been studied. The increase in fibre-to-fibre friction due to the increase in the level of add-on finish on core fibres/sheath fibres/both the fibres increases the yarn tenacity,...
Article
The influence of operational factors on friction in acrylic fibres of 38 mm and 1.65 dtex has been studied. The increase in normal force decreases the coefficient of friction and results in a more pronounced stick-slip effect. The values for friction indices 'a' and 'n' in the equation F=aN n are found to be 0.71 and 0.90 respectively. The sliding...
Article
The influence of core filament surface structure on tensile properties of friction-spun yarns has been studied. The yarn spun from Z pre-twist filament core has superior properties while that spun from S pre-twist filament core shows inferior quality as against the yarn spun with flat filament core. Yarns spun with air-jet textured filament core ex...
Article
The influence of fibre friction on twist structure and tensile properties of filament-core DREF-3 friction spun yarns has been investigated. A 110/48 dtex polyester multi-filament in three different forms – namely, flat, twisted, and textured – was used for the core, and acrylic fibres of 38 mm and 1.65 dtex with three different add-on levels of po...
Article
The influence of fibre-to-fibre friction on structure and tensile properties of staple-core DREF-3 friction spun yarns has been investigated. Acrylic fibres of 38 mm and 1.65 dtex with three different add-on levels of PEG400 finish were used to produce a set of nine yarns, each of 50 tex with a core:sheath ratio of 70:30. It was found that, to a ce...
Article
The superabsorbent acrylic fibre (acrysorb) was spun into ring, rotor and dref-3 yarns, which were knitted to terrysock fabrics. The quality of these fabric samples was evaluated and compared with that of terrysock fabric knitted from cotton ring yarn. The acrysorb yarns performed well in knitting, with the fabrics having better appearance and hand...
