This article contributes to study the influence of weft yarn count on silk fabric properties such as fabric weight in g/m2, tensile strength, breaking elongation and tear resistance in both warp and weft directions. The experiments are implemented with silk fabric specimens using 72D warp yarn and different weft yarns of 48D, 72D, 96D, 120D &144D. | Journal of Science & Technology 122 (2017) 073-076 Study on Influence of Weft Yarn Count on Mechanical Properties of Plain Silk Fabric Hoang Thanh Thao*, Nguyen Minh Tuan Hanoi University of Science and Technology, No. 1, Dai Co Viet, Hai Ba Trung, Hanoi, Viet Nam Received: November 21, 2016; Accepted: October 27, 2017 Abstract Having many precious characteristics, silk fabric offers comfortable feeling with elegant fashion and is always preferred by the customers. However, silk fabric is easily wrinkleable and fragile with reduced properties when it is used. This article contributes to study the influence of weft yarn count on silk fabric properties such as fabric weight in g/m2, tensile strength, breaking elongation and tear resistance in both warp and weft directions. The experiments are implemented with silk fabric specimens using 72D warp yarn and different weft yarns of 48D, 72D, 96D, 120D &144D. The research results show that when weft yarn count increases the fabric weight in g/m2 and the tensile strength as well are increased considerably while the longitudinal tensile strength is slightly decreased, the tear resistance in warp direction is increased while the tear resistance and the breaking elongation in weft direction are unchanged. The research results could be a scientific basis for better selection of weft yarn count to produce silk fabric to meet the quality requirements of the end-use product. Keywords: physical-mechanical properties, weft yarn count, plain silk fabric 1. Problem statement was measured according to ISO 3801-77 standard on Ohaus Digital Scale – US; Tensile strength follows ISO 13934-1-2013 standard on Tensometric Tensile Strength Tester – UK; tear resistance follows ISO 13937-1-2000 standard on Elmatear Tear Resistance Tester – UK and crease recovery angle follows ISO 2313-72 on Crease Recovery Tester Device – UK. 1 Silk is a type of fancy fabric preferred by customers for being more comfortable and fashionable than other .
