TWO-PLY WOVEN STRUCTURE WITH HIGH-STRENGTH AND THERMOPLASTIC FIBERS Russian patent published in 2018 - IPC B29C70/22 D03D1/00 D03D11/00 F41H5/04 

FIELD: textile and paper; individual protection means.

SUBSTANCE: invention relates to a penetration resistant article that can be used to produce protective clothing such as flak jackets, helmets, as well as shields or armor elements, and to the method of its production. Article comprises at least one woven fabric structure (3), having thermoplastic fibers and high- strength fibers with a strength of at least 1100 MPa in accordance with ASTM D-885 standard. High-strength fibers are joined together to form woven fabric (2) of woven fabric structure (3), and the thermoplastic fibers have a weight percent relative to the weight of woven fabric structure (3), ranging from 5 to 35 %. Moreover, the thermoplastic fibers preferably in the form of non-corrugated fabric (6) lie on woven fabric (2) and are connected to woven fabric (2) by the main yarn and/or weft yarn of woven fabric (2) made of high-strength fibers. There are no additional connecting yarns or non-textile connecting means for ensuring connection between woven fabric (2) and thermoplastic fibers.

EFFECT: products resistant to penetration has the properties of protection against impact and/or anti-ballistic properties.
