Description

Protective clothing

The present invention relates to garments made from composite fabrics having good cutting and puncture resistance, and more particularly to garments made from fabrics having a combination of a layer of metal mesh and a textile layer of woven nonmetallic fibers. And the non-metallic fibers include meta-aramid fibers, ultra high molecular weight polyethylene fibers, polyethylene terephthalate fibers, cellulose fibers, polyamide fibers, para-aramid fibers and mixtures of meta-aramid fibers, and para-aramid fibers and carbon One selected from the group of mixtures of fibers.

Protective garments made from para-aramid synthetic fibers such as but not limited to fabrics woven from Kevlar ™, Honeywell Spectra ™, Dynea ™, Black Kevlar ™, and combinations thereof, exhibit excellent resistance to ballistic puncture, It has been successfully used to construct lightweight body armor. Other materials, such as but not limited to Nomex ™, exhibit excellent heat resistance and are used in, but not limited to, personal fire resistant garments such as firefighters, race car drivers, and military flight crews. However, the materials have only average resistance to cutting and slash attacks and puncturing by needles. Thus, garments constructed from such materials, such as but not limited to para-aramid based body armor, provide good protection against shooting, but are not particularly effective against knife or needle threats.

There is a need for garments made from lightweight fabrics that provide a combination of ballistic perforation or heat or chemical attack as well as high resistance to cutting and slash and perforation attacks. It is also desirable that such fabric combinations can be readily used to make lightweight flexible garments such as but not limited to gloves and other attack proof garments.

Meta-aramid fibers are well known and are sold, for example, under the trade name NOMEX ™ by E. I. du Pont de Nemours and Company (Wilmington, DE). The chemical composition is poly (meth-phenylene isophthalamide). These are related to para-aramid fibers, which are also sold under the trade name Kevlar ™ by du Pont and have a chemical composition of poly (para-phenylene terephthalamide). Para-aramid is described in more detail, for example, in US Patent 9644923 ("Composite, protective fabric and garments made specifically"), issued May 9, 2017, the contents of which are hereby incorporated by reference in their entirety. Described.

Ultra high molecular weight polyethylene fibers are, for example, Honeywell International Inc. (Morristown, NJ) and sold as Honeywell Spectra ™ fibers and Koninklijke DSM N.V (Heerlen, Netherlands) as Dyneema ™ fibers.

Ultra high molecular weight polyethylene fibers produce lightweight, high strength materials. They have yield strength as high as 2.4 GPa (350,000 psi) and specific gravity as low as 0.97. High strength steels have comparable yield strengths, while low carbon steels have much lower (about 0.5 GPa) yield strengths. Since steel has a specific gravity of approximately 7.8, this provides a strength-to-weight ratio for these materials, in the range of 8 to 15 times higher than steel.

Fibers are used in body armor, in particular personal body armor, and sometimes as vehicle armor and cut-resistant gloves.

Polyethylene terephthalate fibers are generally known as polyester fibers and are sold, for example, by US Fibers (Trenton, South Carolina).

Cellulose fibers are not only naturally occurring fibers, but are also made synthetically. Naturally occurring fibers include cotton and hemp fibers, and the hemp fibers are woven into a fabric such as linin. Synthetic cellulose fibers are generally known as rayon, for example Grasim Industries Ltd. (Mumbai, India) is sold as Viscose Staple Fiber ™.

Polyamide fibers are generally known as nylons, and various polyamide polymer fibers are sold under the trade name Elvamide ™ by various companies including E. I. du Pont de Nemours and Company (Wilmington, DE).

Mixtures of para-aramid fibers and meta-aramid fibers are not well known, but aramids are well known and are sold, for example, under the trade names Kevlar ™ and Nomex ™ by EI du Pont de Nemours and Company (Wilmington, DE). do. Because of their strength and heat resistance, the materials are often used in protective clothing, such as fireman suits, race car driver suits, and air force pilot suits, typically on separate floors.

Materials woven from fibers that are a mixture of para-aramid fibers and carbon fibers are well known and are sold, for example, under the trade name Black Kevlar by E. I. du Pont de Nemours and Company (Wilmington, DE).
