In this paper seam performance of lightweight fabrics was investigated using two methods: ISO 13936-3 and ISO 13935-2: 2004 + ISO 13936-1: 2004. The aim of the paper is to compare these two methods and to determine whether the same assessment of the seam performance will be obtained. In this study three lightweight woven fabrics were investigated. The obtained results have shown that, both methods used have identical evaluation of the fabrics properties with reference to the seam slippage. The comparison of the results shows that, the seam strength measured according to the method ISO 13935-2: 2004 + ISO 13936-1: 2004 is lower in comparison to the seam strength of the needle clamp method (ISO 13936-3), due to the elimination of sewing thread of the second method. In this case it is determined that both methods give matched assessment of the seam strength performance. Key words: seam, seam slippage, strength, needle clamp |
