Sewability engineering of technical textiles

Abstract

Inspite of profound investigation of sewability assessment and number of theoretical models existing in the textile literature for different fashion fabrics, a model covering technical textile is not available. Hence the challenge addressed in the present work to talk full modeling, and design tool for sewability of nonwoven technical textile (geotextiles). This study evaluated the sewability of technical textile in relation to the sewing needle penetration force (SNPF). The measuring system depends on measuring the change of the electric power under dynamic conditions by using measuring electric circuit and a digital oscilloscope connected to a PC computer. Sewability is defined as a maximum needle penetration force (CN), measurements are realized on home, sewing machine at 100 spm. For sewing the two layers of geotextile (GT) are used. For treatment of results the semi-symmetrical frequency distribution is assumed. Also it was found that needle penetration force and geotextile compressional properties are well related to each other. As can be seen, the results reveal one common feature, i.e. the higher the compressional properties the higher the seam sewability index (less sewing troubles). By providing reinforcement the technical textiles improve the performance of paved roads, and others.
