The purpose of the work is development a novel of hydro-vibration technology for the formation of hats from fabrics, which will expand the functionalities of application of various fabrics.

The work is based on a novel technology of forming hats from different fabrics with the use of liquid-active working environment (LAWE). This hydro-vibration technology is characterized by high efficiency, productivity, manufacturability and potential opportunities when compared to existing technologies. This allows expanding its range of applications and increase functionality.

In the article, hydro-vibration technology is developed for the formation of hats from fabrics. As a result of the experiment, regression dependences of the shape stability coefficient on the formation factors having a close correlation were obtained. The performed optimization allowed determining the optimal values of technological parameters of the vibroforming process from fabrics: LAWE pressure 0.26 MPa, vibration frequency LAWE 4.3 Hz, forming time 74 s.

The use of developed hydro-vibration technology has great practical significance in the textile industry. This technology increases labor productivity and reduces the cost of production of hats due to its high efficiency. Increased efficiency is provided by the use of special equipment, methods and optimal parameters of the hats formation. With sufficient refinement, the developed technology can be applied to other technological processes.

Originality of the work is using liquid-actin working environment at vibroforming of heads of headdresses from fabrics. It is determined that the use of LAWE is effective in the formation of hats. To ensure maximum plasticization of textile fibers in the fabric of the part and increase the force field, it is developed a novel hydro-vibration technology of forming the heads of hats from fabrics.
