The fabric according to the present invention can particularly be used in the manufacture of ballistic vests, hard and soft armor, stab and knife protection systems, and anti-ballistic systems, and they provide a highly reduction of likelihood of ricochets using such systems.

Abstract: The present invention relates to a heat, flame, and electric arc resistant fabric (1) for use as single or outer layer of protective garments. The fabric (1) of the invention comprises at least two separate single plies which are assembled together at predefined positions so as to build pockets (4). The fabric (1) of the invention is made of materials independently chosen from the group consisting of aramid fibers and filaments, polybenzimidazol fibers and filaments, polyamidimid fibers and filaments, poly(paraphephenylene benzobisaxazole) fibers and filaments, phenol-formaldehyde fibers and filaments, melamine fibers and filaments, natural fibers and filaments, synthetic fibers and filaments, artificial fibers and filaments, glass fibers and filaments, carbon fibers and filaments, metal fibers and filaments, and composites thereof.

Abstract: This invention relates to a flame-resistant spun staple yarns and fabrics and garments comprising these yarns and methods of making the same. The yarns have 25 to 90 parts by weight of a polymeric staple fiber containing a structure derived from a monomer selected from the group consisting of 4,4?diaminodiphenyl sulfone, 3,3?diaminodiphenyl sulfone, and mixtures thereof; and 10 to 75 parts by weight of a textile staple fiber having limiting oxygen index of 21 or greater, based on 100 parts by weight of the polymeric fiber and the textile fiber in the yarn.

Abstract: A substantially torqueless composite dual core-spun yarn (10) is produced by introducing two slivers (30A,30B) forming a covering (30) together with a central (20) core in a spinning triangle (40). The core (20) is fed overtwisted S or Z and the slivers (30A,30B) have an opposite Z or S twist corresponding to about 30% to 70% of the twist of the fed overtwisted core (20) that detwists during spinning. The inelastic core (20) is fed at controlled speed to compensate for the angle of feed and to compensate for detwisting, and is guided into the spinning triangle (40) by a guide groove (52) in a feed roller (50).

Abstract: This invention relates to heat and flame resistant single ply fabric for use as a single or outer layer of a protective garment for a wearer. The fabric comprises at least one warp system and at least two weft systems. The warp system comprises a blend of 60 to 90 wt-% poly-m-phenylenisophtalamid (meta-aramid) and 10 to 40 wt-% poly-p-phenylenterephtalamid (para-aramid). The first of the at least two weft systems comprises a blend of 85 to 95 wt-% meta-aramid and 5 to 15 wt-% para-aramid. The second of the at least two weft systems essentially comprises para-aramid.

Abstract: A substantially torqueless composite dual core-spun yam (10) has a substantially inelastic central hard core (20) covered with a dual-spun fiber covering (30). The central hard core (20) has an elongation at break less than 50% and a Z or S twist, and the fiber covering (30) comprises fibers twisted on the core (20) with an S or Z twist opposite to that of the core. The opposite twists of the core (20) and of the covering (30) exert opposite and substantially equal torques. This yarn is produced by introducing two slivers (30A,30B) forming the covering (30) and a central (30) core in a spinning triangle (40). The core (20) is fed overtwisted S or Z and the slivers (30A,30B) have an opposite Z or S twist corresponding to about 30% to 70% of the twist of the fed overtwisted core (20) that detwists during spinning.

Abstract: A thermally-resistant composite fabric sheet for use as single or outer layer of protective garments, comprises inside and outside fabric layers (B,A) joined together by an array of connection lines (12,22,32) arranged so that the inside layer forms bubble-like pockets (16) when the outside layer (A) is caused to shrink by the external application of intense heat. The array of connection lines (12,22,32) is constituted by a plurality of isolated single connection lines (22) and/or by a plurality of isolated groups of connection lines (12,32), for example forming a series of Y or V shapes. The connection lines are arranged at different angles and are spaced apart from one another to leave gaps (42) where the two layers (A,B) are not connected to one another. These gaps (42) unite a continuous expanse (40) of the two unconnected layers that surrounds each isolated connection line (22) or group of connection lines (12,32).
