Technical Field
The present invention relates to a garment made of a composite fabric having excellent cut and puncture resistance, and more particularly, to a garment made of a fabric having a combination of a metal mesh layer and a woven non-metal fiber fabric layer, the non-metal fiber including one selected from the group consisting of meta-aramid fiber (meta-aramid fiber), ultra-high molecular weight polyethylene fiber, polyethylene terephthalate fiber, cellulose fiber, polyamide fiber, a mixture of para-aramid fiber (para-aramid fiber) and meta-aramid fiber, and a mixture of para-aramid fiber and carbon fiber.
Background
From para-aramid synthetic fibers (such as, but not limited to, Kevlar)TM、Honeywell SpectraTM、DyneaTM、Black KevlarTMAnd combinations of these) exhibit excellent ballistic resistanceAnd have been successfully used to construct lightweight body armor. Other materials (e.g., without limitation, Nomex)TM) Exhibit excellent heat resistance and are useful in fire resistant garments for personnel such as, but not limited to, firefighters, racing drivers, and military aircraft personnel. However, these materials only have an average resistance to cutting and slashing and to needle-stick. Thus, garments constructed from such materials (such as, but not limited to, para-aramid based body armor) provide good protection against gunshot, but are not particularly effective against knife or needle threats.
There is a need for a garment made of lightweight fabric that provides a high degree of resistance to bullet breakdowns or a combination of heat or chemical attack and cut and slash and puncture attacks. It is also desirable that such a combination of fabrics can be readily used to make lightweight flexible garments such as, but not limited to, gloves and other anti-attack garments.
The related prior art includes:
us patent 6,581,212 entitled "Protective clothing" to Andresen, 24/6/2003, describes a Protective garment for protecting body parts against cuts or punctures, comprising an inner layer, a Protective layer and an outer layer, the Protective layer being formed from a mesh of woven wires, the wires having a thickness of between 0.03mm and 0.20mm and the holes in the mesh being between 0.05mm and 0.45 mm.
Various implementations are known in the art, but do not solve all of the problems addressed by the invention described herein. Various embodiments of the present invention are illustrated in the accompanying drawings and will be described in more detail below.
Disclosure of Invention
Inventive protective garments made from novel composite protective fabrics are disclosed.
In a preferred embodiment, the protective garment wearable by a person may be made of a composite fabric in which a metal mesh layer is placed in proximity to a non-metal fabric layer.
The metal mesh layer may be formed, for example, from any metal that can form a suitable fiber, such as, but not limited to, aluminum, beryllium, chromium, cobalt, copper, erbium, gold, indium, iron, lead, nickel, platinum, silver, tantalum, tin, tungsten, uranium, zinc, and zirconium, or some combination of these metals or alloys formed from these metals.
The non-metallic fabric layer may be, for example, a facing formed from fibers including well-known facing fibers such as, but not limited to, para-aramid fibers, meta-aramid fibers, ultra-high molecular weight polyethylene fibers, polyethylene terephthalate fibers, cellulosic fibers, polyamide fibers, mixtures of para-aramid fibers and meta-aramid fibers, and mixtures of para-aramid fibers and carbon fibers.
Forming the non-metallic fabric layer may be formed, for example, by any suitable method for interweaving yarns, such as, but not limited to, weaving, knitting, crocheting, knotting, or felting.
The potential utility of such a combination can be illustrated by the example where the fibers of the fabric layer are para-aramid fibers. When this fabric layer is placed in close proximity to the stainless steel mesh layer, it has been found that a composite is produced that has a surprising puncture resistance property that is 30% to 40% higher than would be expected from the linear combination of cut and puncture resistance properties of each individual layer, while maintaining the combined ballistic and needle resistance of each layer. Thus, combining facestock layers made from other known facestock fibers can produce similarly surprising enhanced combined protective properties.
In a preferred embodiment, a garment can be made that: wherein one or more fabric layers may be placed adjacent to one or more metal mesh layers and sandwiched between inner and outer protective layers, which may be joined together at their peripheries.
In a preferred embodiment, the fabric layer may be made of fibers of 10dtex or less, while the
In another preferred embodiment of the present invention, the composite fabric may have at least three layers and take the form of a first fabric layer and a second fabric layer with a metallic mesh layer sandwiched therebetween. The fibers in the first fabric layer may be, for example, well-known facing fibers such as, but not limited to, para-aramid fibers, meta-aramid fibers, ultra-high molecular weight polyethylene fibers, polyethylene terephthalate fibers, cellulosic fibers, polyamide fibers, mixtures of para-aramid fibers and meta-aramid fibers, and mixtures of para-aramid fibers and carbon fibers, while the fibers in the second fabric layer may be any of the fibers in the group other than the fibers used in the first fabric layer.
As described in more detail below, the number and arrangement of the first fabric layer, the second fabric layer, and the metal mesh layer may be adjusted in various ways to accommodate materials used in the manufacture of various wearable protective garments, such as, but not limited to, gloves, attack resistant vests, protective pants, protective leggings, knee guards, protective sleeves, "chainsaw" pants, protective vests, helmets and helmets (headgears), protective jackets, and protective shoes.
Accordingly, the present invention successfully imparts the following and other desirable and useful benefits and objectives not mentioned.
It is an object of the present invention to provide an improved wearable protective garment that can combine properties such as high levels of ballistic resistance, cut and slash resistance, puncture and needle resistance, and heat resistance.
It is another object of the present invention to provide a cost-effective lightweight material for protective garments.

Detailed Description
Preferred embodiments of the present invention will now be described in more detail with reference to the figures, in which like elements in different figures are identified by like reference numerals as much as possible. These embodiments are provided by way of explanation of the invention, however, the invention is not limited thereto. Various modifications and alterations to this invention will become apparent to those skilled in the art upon a reading of this specification and a review of the accompanying drawings.

The fabric layer may be formed, for example, by any suitable method of interlacing yarns, such as, but not limited to, weaving, knitting, crocheting, knotting, or felting, or some combination of these methods.
Meta-aramid fibers are well known, for example from WilmindU Pont DE Nemours and Company, gton, DE under the trade name NOMEXTMFor sale. Their chemical composition is poly (meta-phenylene isophthalamide). They are also sold by du Pont under the trade name KevlarTMThe para-aramid fiber of (1) has a chemical composition of poly (para-phenylene terephthalamide). Para-aramid is described in more detail, for example, in U.S. patent 9644923 entitled "Composite, protective fabric and catalysts male of," issued to Andresen on 9/5.2017, the contents of which are incorporated herein by reference in their entirety.
Ultra-high molecular weight polyethylene fibers are, for example, available from Honeywell International Inc. of Morristown, NJ as Honeywell SpectraTMFibers and Koninklijke DSM N.V. by Heerlen, Netherlands as DyneemaTMThe fiber is sold.
The ultra-high molecular weight polyethylene fiber can be used for producing light-weight and high-strength materials. Their yield strength is as high as 2.4GPa (350,000psi) and specific gravity as low as 0.97. High strength steels have comparable yield strengths, while low carbon steels have much lower yield strengths (about 0.5 GPa). Since the specific gravity of steel is about 7.8, the strength to weight ratio of these materials is 8 to 15 times higher than that of steel.
These fibers are used in armour, particularly personal armour, and sometimes also as vehicle armour and cut-resistant gloves.
Polyethylene terephthalate Fibers are commonly referred to as polyester Fibers, such as those sold by US Fibers of Trenton, south carolina.
Cellulose fibers are found both in naturally occurring fibers and synthetically produced fibers. Naturally occurring fibers include cotton fibers and hemp fibers, wherein the hemp fibers are woven into a fabric such as a gusset (lin). Synthetic cellulosic fibers are commonly referred to as rayon, for example, by Mumbai, Industries Ltd. of India, as Viscose Stack fiberTMFor sale.
Polyamide fibers are commonly referred to as nylons and various polyamide polymer fibers are available from several companies (including Wilmington, e.i.d. DE)u Pont de Nemours and Company under the trade name ElvamideTM) For sale.
Mixtures of para-aramid fibers and meta-aramid fibers are not well known, but aramid fibers are well known, such as Kevlar (R) under the trade name Kevlar (R) by E.I. du Pont DE Nemours and Company, Wilmington, DETMAnd NomexTMFor sale. Because of their strength and heat resistance, these materials are often used in protective clothing (e.g., firefighter uniform, racing car gear uniform, and air force pilot uniform), although often in separate layers.
Materials woven from fibers that are blends of para-aramid fibers and carbon fibers are well known, such as that sold under the trade name Black Kevlar by e.i. du Pont DE Nemours and Company of Wilmington, DE.

The metal mesh may be formed, for example, by any suitable method of interlacing yarns, such as, but not limited to, weaving, knitting, crocheting, knotting, or felting, or some combination of these methods.
In a preferred embodiment of the invention, the mesh is preferably a woven metal mesh, more preferably a woven mesh made of stainless steel fibers having a diameter of 0.2mm or less and having mesh openings of 0.45mm or less. Such webs have been found to have good resistance to cutting and slashing as well as to needle stick penetration and have been used in protective apparel such as, but not limited to, protective gloves such as those described in, for example, U.S. patent 6,581,212 to Andresen, 6-24/2003, the contents of which are incorporated herein by reference in their entirety.

In a preferred embodiment of the invention there may be between 20 and 28 fabric layers and between 8 and 12 metal mesh layers, and in a more preferred embodiment there are 24 fabric layers and 10 metal mesh layers.
However, it will be apparent to those skilled in the art that the protective composite fabric shown in FIG. 6 and described above may be used in a variety of other protective garments. For example, the introduction of pants or leggings made of such materials may provide significant protection against piercing attacks such as those of industrial cutting machines (e.g., without limitation, electric saws), for example. Similarly, the material or variants thereof may be incorporated into other protective apparel products, such as, but not limited to, shoes, boots, gloves, hard hats, or sleeves.

As mentioned above, the applicant has noted that when a particular fabric layer is combined with a metal mesh layer, its puncture resistance is unexpectedly increased by 30% to 40%.
Thus, by weaving the fibers into a single layer fabric, a similar synergy in the properties of the metal fibers and the fabric fibers can also be achieved.

The folded
The purpose of having one or more metal mesh layers or one or more fabric layers of the protective material with a truncated finger or thumb extension may be to allow additional flexibility for the wearer's corresponding finger. For example, the glove may be used by a person who wishes to use a firearm while wearing the glove. For example, having additional dexterity and less bulk (bulk) in the thumb and forefinger of the glove may make it easier for the wearer to hold a pistol and fire a shot.
In an alternative form of glove with cut-back protection, there may be additional material sized and shaped to cover the remainder of the thumb, but not to connect with the remainder of the pictographic pattern. In this way, flexibility may be maintained while protection may be provided for a large portion of the thumb and fingers.
