A number of experiments were conducted to optimize the hydro-jet forming and its optimal technological parameters that were determined. Formed headwears from coat fabrics and costume assortment. Completed comparison of developed technology with existing and installed economic effect from its application.

As a rule, hats are picked up under a suit using a similar material. Modern fashion trends intensively offer headdresses costume supplement of various shapes and materials. But for today headwear quality assurance requires the improvement of structures and technologies. It is also necessary to reduce the cost of materials and improving their consumer properties. For better fitting of clothes on a person's figure, it is necessary to give it a volumetric form in certain areas. This is realized in accordance with the artist's plan and the anatomical features of the body structure. There are many technologies and ways to solve this problem for today. Parts quality of volume form headdresses conditioned by structural performance fabrics. Also – the way of formation, an important factor of which is the power field. For a rational selection of formation modes, is expedient to forecast the process due to the analysis of applied actions to the detail of the loads headdresses. Also perspective is development of recommendations regarding the application of different loads schemes taking into account the features of the contour parts. Increasing consumer demands for product quality makes use of new methods, techniques and research equipment for the development of production technologies. Providing details of headdresses difficult spatial form from fabrics without constructive intervention is an extremely hard task. To do this is necessary plastify the fabric and attach it some effort. This scheme is implemented in forming volumetric details of headwear by hydrojet method due to use liquid-active working environment (LAWE) [1]. It plastify the fabric and transfers the molding effort by flooded hydrojet stream [2]. Conducting experiments on the specified equipment using LAWE will allow to optimize the formation process parts of hats of different fabrics. This will improve the quality of the products. Thus, the actual task is to conduct research the process of hydrojet forming of women's headwear of hospitality establishments to determine the optimal technological parameters of the specified equipment. Also, it is necessary to determine the economic effect of the application proposed technology. As known, fibers have certain deformation properties, which then transmitted to threads and then – fabrics. Considering in the complex the composition and structure of the fiber, we can make a definite conclusion. It is established that the most flexible are cotton fibers and the hardest – linen. Forming fabrics of wool fibers is happening at the expense of scales located on their surface. This significantly increases the coefficient of friction with the joining of fibers [3]. Adding chemical fibers to natural improves the shape resistance of the fabric. In particular, the use of wool with fibers, which have high plastic deformation, will increase the quality of the formed detail [4]. With decreasing fabric density, but with the same thickness of fibers and interlacing and with a decrease in the number of fibers by 10 cm the fabric becomes more mobile [5]. With a decrease in fabric bonding, the fibers are easier to move one to another and stiffness of fabric
