Abstract

Upholstery fabrics' industry is very important, so it should be cared to achieve better functional properties. Production techniques of these fabrics are enormous. Whether warp knitted fabrics are highly used, weft knitting technique is rarely used. In the present study a group of fabrics is produced using weft knitting technique on rectangle weft knitting machine, different raw materials Nm 28/2, two fabric structures (Rib – Interlock) with gauge 5 and 7. The aim of this work is to study the effect these factors on the functional properties of upholstery fabrics. The results show that it is possible to produce upholstery fabrics using weft knitting technique on rectangle weft knitting machine, it is determined, also, that there is significant effect of the tested factors on fabric weight per unit area, thickness, bursting strength, and dimensional stability. The interlock, gauge 7, Cotton/Polypropylene sample shows the best results, followed by interlock, gauge 7, Acrylic/ Polypropylene sample, then interlock, gauge 7, Cotton sample. The Rib, gauge 5, Acrylic sample shows the worst results. It is recommended to use weft knitted fabrics produced on rectangle weft knitting machine as upholstery fabrics, preferring Polypropylene blends to achieve better functional properties
