Textile & Engineering College, Bhilwara, Rajasthan, India In this study, effect of relaxation on the properties of acrylic- silk blended fabrics has been examined. The effect of wet relaxation as well as full relaxation has been examined. Bulk in the silk yarn was produced by blending shrinkable acrylic fibre with silk with varying blend percentage. Single jersey weft knitted fabrics were prepared from acrylic silk blended yarns such as 100% shrinkable acrylic A10, 80% shrinkable acrylic and 20% silk (A8S2), A6S4, A5S5, A4S6, A2S8 and 100% silk S10. It was found that after wet and full relaxation the course/cm, wales/cm, stitch density, thickness and bulk of acrylic/silk fabrics increased whereas stitch length reduced. After wet and full relaxation the increase in th...

Asian Resonance   (P: ISSN No. 0976-8602 RNI No.UPENG/2012/42622 VOL.-7, ISSUE-1, January-2018 E: ISSN No. 2349-9443) Abstract   Rajiv Kumar  Associate Professor, Deptt.of Textile Technology, M.L.V. Textile & Engineering College, Bhilwara, Rajasthan, India. Due to limited availability and higher cost of cotton fibre, polyester/ viscose knitted fabrics are increasingly used these days. The aim of the paper is to compare the properties of 65/35 Polyester-Viscose single jersey knitted fabric with that of 100% Cotton single jersey knitted fabric having same particulars. It was found that bursting strength of P/V knitted fabric is greater than cotton fabric, due to higher elongation at break values of P/V yarn. Abrasion resistance of P/V fabric was also greater than that of cotton fabric. The air permeability of cotton fabric is slightly less than P/V fabric due to bigger diameter and higher value of hairiness in case of cotton yarn. Moisture regain of cotton fabric is...

Textile & Engineering College, Bhilwara, Rajasthan In this study effect of blend percentage on the properties of silkacrylic blended knitted fabrics has been analysed. For this purpose, single jersey weft knitted fabrics were prepared from acrylic silk blended yarns such as 100% shrinkable acrylic A10, 80% shrinkable acrylic and 20% silk (A8S2), A6S4, A5S5, A6S4, A8S2 and 100% silk S10. Fabric properties in dry relaxed condition were analyzed. Effect of blend percentage on course/cm, wales/cm, stitch length, stitch density, loop shape factor, tightness factor, thickness and skewness of silk- acrylic blended singlejersey knitted fabrics has been studied. It has been found that course/cm first increases, then reaches maximum at 50/50 silk- acrylic blend and then ...

Textile & Engineering College, Bhilwara, Rajasthan Fabric hand has become indispensable property of fabric. It indicates that whether customer will prefer to purchase the fabric or not. This paper reports comparison of low stress mechanical properties (tensile, bending, shear, surface and compression properties) and Total hand Value of 100% silk, 100% acrylic, silk/ acrylic 50/50 blended knitted fabric to very common cotton knitted fabric of similar construction. It was found that comparatively lower values of elongation are observed for 100% acrylic and acrylic-silk 50/50 blend (A5S5) in comparison to 100% silk and cotton fabric. This is due to higher value of yarn diameter resulting in more area of contact within the threads and more resistance during tensile elon...
