**7. Conclusions**

Today, the textiles materials are involved almost in all areas of products. We require from the textile products special features and high functional utility, which include water permeability, resistance to pressure, wear and tear or seams, air permeability, and aesthetic appearance. For more demanding products, such as inflatable boats, protective and sports clothing, etc., the traditional sewing methods no longer meet the technical requirements for joining the garment parts nor the aesthetic appearance of the products. The textiles materials, methods, machinery, and adhesives necessary for the heat joining such as fusing and hot air welding apparel seams are today more and more involved in the commercial market.

In comparison with the hot air welding, the fusing technology has much longer tradition. In fact, the main purpose of fusing is to improve the aesthetic appearance of a garment, as well as to simplify the garment manufacturing process. Further, hot air welding represents today a significant competition to the traditional sewing and becomes one of the most important technologies in the production of various functional and nonconventional textiles. It will be even more important in the future. The hot air welding provides faster production, low waste material, and it is energy‐efficient, therefore it is expected that the merged parts in textile end‐ products should completely meet the users' expectations.

Besides fusing and hot air welding for seamlessly joining the textile materials, we can also use other welding techniques, such as laser, ultrasound, warm air, and high‐frequency welding. The selection of a welding technique depends on the function of the final product, type of material used, and the desired quality of welded joints. To summarize, welding of textile materials has a significant potential for manufacturing of textile products of the future.
