PRODUCTION OF NONWOVEN TEXTILE MATERIAL WITH PROCESSING TO ADD PROTECTIVE AND ANTISTATIC PROPERTIES THERETO Russian patent published in 2015 - IPC D04H3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to production of nonwoven textile material from polymers based on at least one polyolefin. Note here that this process comprises treatment to add protective and antistatic properties for protective clothes suitable for use in industry and health protection. In compliance with this process, polyolefin polymer suitable for formation of fibres is mixed with first additive to modify the surface characteristic and to migrate through polymer bulk. Then, obtained mix is used for formation of at least one layer of nonwoven textile material with the help of technology of fibre formation from the melt. Before termination of the first additive migration and stabilisation of resultant protective properties on fibre surface, second additive is applied on the layer that can modify the material antistatic properties. Thereafter, produced nonwoven textile material is held at definite temperature and relative humidity for time required for migration of first additive to the surface and modification of second additive thereon.

EFFECT: higher efficiency.
