[0011] As desired, protective clothing has been developed for firefighters and other related workers that: a) is fire resistant without chemical treatment, b) remains fire resistant after cleaning or washing, c) is designed to be worn under other layers of fire resistant clothing, d) wicks moisture away from the body of the wearer, e) provides side-to-side comfort for the wearer, f) provides additional design features that aid these workers in wearing the clothing without traditional problems or issues with that clothing.

[0012] Specifically, a contemplated shirt, as disclosed herein, includes a body component, comprising a front component, a back component, at least two side components, and at least two sleeve components, wherein the body component comprises a fire-resistant material. In some embodiments, the body component consists entirely of a fire-resistant material. It should be understood that the fire resistant material is not chemically treated with a chemical that makes the material fire resistant. This concept will be described in detail herein.

[0013] Contemplated shirts, as disclosed herein, comprise a body component. As used herein, the phrase body component means that it is designed to be worn over and around the body. Contemplated body components may comprise any suitable fabric, as long as the fabric is fire resistant without any chemical coatings or application. It should be understood that there may be a fiber treatment process that dyes the fabric or keeps it from shrinking, but there are no fire-resistant chemicals applied to an otherwise non-fire-resistant shirt to make it fire resistant.

[0014] In some contemplated embodiments, contemplated fabrics comprise acrylic, rayon, nylon, or a combination thereof. In other embodiments, the rayon consists of cellulose fiber made from dissolving pulp (bleached wood pulp) using dry jet-wet spinning. In yet other embodiments, contemplated rayon is provided under the tradename LYOCELL, which will be referred to herein as cellulosic rayon. As contemplated herein, fabrics comprise at least 20% cellulosic rayon. In some embodiments, fabrics comprise at least 30% cellulosic rayon.

[0015] In some embodiments, contemplated fabrics comprise at least 40% acrylic fiber. In other embodiments, contemplated fabrics comprise at least 50% acrylic fiber. And in yet other embodiments, contemplated fabrics comprise about 55% acrylic fiber.

[0016] In some embodiments, contemplated fabrics comprise at least 5% nylon fiber. In other embodiments, contemplated fabrics comprise at least 10% nylon fiber. And in yet other embodiments, contemplated fabrics comprise at least about 15% nylon fiber.

[0017] In one contemplated embodiment, a contemplated shirt comprises a fabric having about 55% acrylic fiber, about 30% cellulosic rayon fiber, and about 15% nylon fiber. In yet another contemplated embodiment, a contemplated shirt comprises a fabric consisting of about 55% acrylic fiber, about 30% cellulosic rayon fiber, and about 15% nylon fiber. In another contemplated embodiment, a contemplated shirt comprises a fabric consisting essentially of about 55% acrylic fiber, about 30% cellulosic rayon fiber, and about 15% nylon fiber. In some embodiments, a contemplated fabric is referred to by the tradename TECHTT4, which is manufactured by TenCate.

[0018] It should also be noted that contemplated fabrics should meet certain levels of protection criteria. Contemplated fabrics must have less than about a 2 second response to a vertical flame test, which is the time it takes for a flame to be extinguished after being exposed to a vertical flame for 12 seconds. Contemplated fabrics must also have a char length of less than 6 inches6 inches, which is the actual char length as measured after the vertical flame test. Contemplated fabrics should have an arc thermal protective value or ATPV of at least 4.8 CAL/CM2. Contemplated fabrics should be as light in weight as possible, in order to be as comfortable as possible when being worn by firefighters. They should also be able to stretch and should be able to recover and form back into shape easily.

[0019] A contemplated body component 100 is shown in FIG. 1 and comprises an inside 160, an outside 170, a front component 110, a back component 210, at least two side components 130, and at least two sleeve components 120. Each of these components will be described herein. However, it should be understood that each of these components are connected to one another using a fire-resistant thread component, which may comprise a single-ply thread or a multi-ply thread. If the contemplated thread is a multi-ply thread, it is contemplated that each ply may contain or comprise the same material or may be made from materials different from the other ply or plies. The contemplated embodiments shown in FIGS. 1-3 are made from the materials disclosed herein.

[0020] In some embodiments, a contemplated body component 100 comprises a sewn-in neckline 150 that extends around the neck opening. In other embodiments, neckline 150 is made from the same material as the other components, but it is stitched in order to make it more durable than the rest of the body component. A contemplated stitching line is shown in FIG. 1.

[0021] Any suitable fire-resistant thread component would be contemplated. However, in some embodiments, a contemplated fire-resistant thread comprises a thread made from aramids. In other embodiments, a contemplated fire-resistant thread comprises a thread made from a meta variant of the aramids. In yet other embodiments, a contemplated fire-resistant thread comprises the tradename NOMEX, which will be referred to herein as an aramid variant.

[0022] A contemplated front component 110 is coupled with at least one sleeve component 120 and at least one side component 130. As used herein, the term coupled means that the front component, the at least one sleeve component, the at least one side component, or any combination thereof, may be transitionally-connected, in that one or more of them are not physically separated components, or may be physically connected, in that one or more of them are initially physically separated components that are stitched together. A contemplated front component comprises a directional distance line 116, from the top 112 of the front component, near the head of the wearer, to the bottom 114 of the front component, near the waist of the wearer.

[0023] A contemplated back component 210 is coupled with at least one sleeve component 120 and at least one side component 130. A contemplated back component 210 is designed to cover the back (not shown) of the wearer (not shown). A contemplated back component 210 comprises a directional distance line 216, from the top 212 of the back component, near the head of the wearer, to the bottom 214 of the back component, near the waist of the wearer. It is contemplated that the directional distance line 216 of the back component is at least 10% longer than the directional distance line 116 of the front component. In other embodiments, it is contemplated that the directional distance line of the back component is at least 25% longer than the directional distance line of the front component. In yet other embodiments, it is contemplated that the directional distance line of the back component is at least 40% longer than the directional distance line of the front component. It should be understood that this back component length is designed to fit better into the pants of the wearer, in order to provide better comfort and coverage during wearing.

[0024] In some embodiments, a contemplated back component comprises a shoulder component 280 that provides additional width to the shoulder area and may also strengthen the area around the neck.

[0025] A contemplated shirt also comprises at least two sleeve components. In contemplated embodiments, where at least one of the sleeve components is physically coupled to the front component and the back component, they are coupled using a raglan coupling technique. This technique is designed to run the seam down from the neck area of the shirt in an angle from the neck area down to near the armpit area of the shirt. In a raglan coupling technique, there are no seams on the top of the shirt running down the shoulder area or under the sleeve. This technique is important, because it provides additional comfort for firefighters when they are wearing additional layers on top of the contemplated shirt.

[0026] Contemplated shirts also comprise at least two side components, which are designed to provide maximum flexibility of movement for the wearer. In some embodiments, the side components are considered or function as gussets, in that they are sewn in or physically coupled with the other components, in order to strengthen it, enlarge it, or a combination thereof.

[0027] Thus, specific embodiments, methods of protective clothing for firefighters and other related professionals and workers have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the disclosure herein.
