Difficulties in the process of producing table linen in weaving

Weaving of table linens (table covers, decorative tablecloths and napkins) on large width weaving machines in a form of multiple tapes, weft cutting and selvedge forming on the edge of tapes are common and effective way of their production. However, the process of chemical finishing (desizing, bleaching, dyeing, mercerising, etc.) requires larger fabric widths, meaning that the napkins and table cloth have to be stiched back together after weaving in order to obtain the appropriate width corresponding to the working width of the finishing machines. Uneven thread tension in the seam, as well as inner fabric tension, and exposure to chemical agents, in wet and dry conditions, with various temperature conditions, can affect the thread in a seam and cause the seam damage. According to the obtained results, it is apparent that the thread from the seams has a lower tensile stiffness compared to the thread that is treated in the same way in finishing processes and to the thread from the cross- wound cone. The tensile stiffness of the sewing thread decreases mostly after the bleaching process. By visual inspection, it was found that the sewing thread damage was very localized and by marking these points prior tensile testing, it is found that the thread breakpoints where on exact places.
