Sažetak
In the world oh high performance fibers and textiles, which are suitable for making a variety of protective clothing, special attention should be focused on applied sewing techniques and seam performance. Although it is usually taken for granted that new joining techniques (welding & bonding) ensure seam impermeability, it is not always so. Generally, there is no horizontal or vertical seam leakage in both types of fabric welding (US or HF), provided impermeable fabrics are used in the process. But, according to the some of our recent investigations on ultrasonically welded seam performances we may say that the only instance where horizontal permeability could occur is in ultrasound welding, if in welding an engraved roller is used with discontinuous pressing surface (dotted weld, weld with a series of discontinuous lines). Horizontal leakage is avoided if engraved anvil wheels with a single or multiple continuous lines are used, or anvil wheel with engraved sinusoid or zigzag pattern. However, to make a weld vertically impermeable it is necessary to optimize processing parameters which, if inappropriate, could cause micro-porosity and make the product inadequate for some of the intended end-uses (protective clothing, tents, reservoir etc.).
