Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an outer material for use clothing as well as an insert clothing item.

[0002] The most frequent cause of death among firefighters in use is not burns, but is the overload in the form of a circulatory collapse due to the increased body core temperature. This increase in the body core temperature is due to the fact that the heat generated in the clothing can not be dissipated or can be removed only inadequately. As a rule, a fire brigade is wearing an undergarment as the first layer. Then, as a second layer, a lining material, then a third layer, the membrane, and finally a fourth layer, follow the outer material of the insert.

[0003] This layer structure hinders both the water vapor passage and the passage of sweat in liquid form. Without the passage of water vapor and liquid water, the heat produced by the body can not be dissipated. The consequence is the increase of the body core temperature with serious health consequences.

[0004] Application clothing is usually constructed as follows: A lining serves as heat insulation. This is followed by a membrane with a textile side, which serves as a wet protection and as additional thermal insulation. The third layer is followed by an outer material which protects against flame contact. It also protects against radiant heat and mechanical effects. Each of these layers increases the resistance for the water vapor and the liquid sweat with respect to the transport from the inside to the outside. In particular, this affects the feed and the membrane.

[0005] It is an object of the present invention to improve use clothing, in particular for fire-fighting personnel, in such a way that the above-mentioned disadvantages do not arise or only occur in a reduced form.

[0006] This object is achieved according to the invention by an outer material for use clothing, which is constructed as a double fabric with a top fabric and a lower fabric, the upper fabric and the lower fabric layer being joined together. By means of this measure, the outer material is changed in such a way that a lining is no longer necessary for the protection because the outer material already assumes the function of the feed, in particular the heat insulation. With the elimination of the feed, significantly more water vapor and also liquid sweat and thus heat can be removed from the clothing. The heat insulation is thus displaced externally, namely into the outer material. The lower fabric is designed in such a way that it changes under the influence of heat, Whereby an additional air cushion is formed on the inner side (the body-facing side) of the outer material. This air cushion increases the insulation protection of the entire system and makes the feed superfluous. The resistance to water vapor and liquid sweat is considerably reduced.

[0007] It is particularly preferred if indentations are formed on the underside of the outer material. Air cushions can be formed in these indentations, which act as insulation. The indentations can reach up to the upper tissue.

[0008] The top fabric may have aramid and antistatic material components. Suitable antistatic components are, for example, carbon fiber-coated carbon fibers. Other antistatic components are, for example, Belltron, Negastat, Resistat, Steel, etc. The fiber components of the yarns of the upper fabric are mixed intimately, ie all components are mixed together in corresponding machines before the yarn is produced and then spun to a yarn. The antistatic components are spun in the warp and warp threads of the upper fabric.

[0009] It is particularly preferred if the lower fabric has aramid. Aramid fibers have a negative coefficient of thermal expansion in the direction of the fibers, ie become shorter and thicker on heating. As a result, the sub-fabric contracts slightly under heat, as a result of which the indentations are enlarged, so that a thicker insulation layer is formed. Furthermore, aramids are extremely heat-resistant. They easily exceed temperatures above 370 ° C without melting and are highly heat resistant. In this respect, they also form a good protection for a firefighter when he wears an insert clothing which has an outer material according to the invention.

[0010] According to a particularly preferred embodiment, the lower fabric can be connected to the upper fabric by means of binding points. The upper fabric and the lower fabric are each composed of a basic binding. For example, the upper fabric can consist of a twill weave and the lower fabric can be made from a canvas binding. If the basic binding of the upper tissue is modified (additional lowering of warp threads) in order to create a connection to the lower tissue, AB binding points are referred to. If the binding of the lower tissue is altered (additional lifts of warp threads), in order to achieve a connection of the two tissues, one speaks of AN binding points. The upper fabric and the lower fabric are simultaneously woven, with both the upper fabric and the lower fabric each having a thread system (warp and weft).

[0011] According to a further development it can be provided that the threads of the lower fabric, which serve to connect to the upper fabric, form the form of a grating. The indentations can be formed in the meshes of the grid. For example, it can be provided that, after a predetermined number of warp threads of the upper fabric, one or more warp threads of the lower fabric are incorporated into the upper fabric. Warp threads of the lower fabric can be incorporated into warp threads of the upper fabric in the ratio 1: 2. In particular, for example, four warp threads can be drawn in for the later sub-fabric in the weaving harness and reed.

Furthermore, it can be provided that, after a predetermined number of weft threads of the upper fabric, one or more weft threads of the lower fabric are incorporated into the upper fabric. For example, weft threads of the lower fabric can be incorporated in the weft threads of the upper fabric in a ratio of 1: 1.

[0013] Preferably, the yarns of the lower fabric are formed of a spun-black material. Through the color selection and the selection of the suitable binding points, it can be achieved that the black material of the lower fabric does not adversely affect the appearance of the upper fabric. The threads of the lower fabric are therefore practically not visible in the upper fabric.

[0014] The improved insulating effect can be achieved by at least the sub-fabric contracting under the influence of the flame. This can be effected by suitable material selection. The indentations are provided on the underside of the outer material immediately after the weaving process. As a result of the following equipment, the fabric can be stretched and extremely flattened. When heated, the outer material can develop somewhat again within established parameters. This applies in particular to the sub-fabric. As a result, the indentations or free spaces / void spaces in the lattice of the lower fabric again become more pronounced, so that larger free spaces are created for insulating air.

[0015] Within the scope of the invention, furthermore, an insert clothing piece, in particular a fire brigade clothing, which comprises an outer material according to the invention. Such an article of clothing has a lesser weight since no lining is necessary. Nevertheless, this lining garment has a high insulating effect since an insulating layer can form under heat effect between the outer material and a following membrane. The insert article thus has an insulating layer on the outside of the membrane, whereas it has hitherto been customary to provide an insulating layer, in particular a lining, on the body side of the membrane.

[0016] To this extent, it can be provided that the insert clothing piece has a water vapor permeable membrane. This ensures that the water vapor can escape to the outside. The outer material according to the invention is designed in such a way that water vapor, which comes from the membrane, can simply be discharged to the outside.

[0017] The membrane can directly adjoin the lower fabric of the outer material. As a result, it is possible for air cushions to form between the membrane and the lower fabric of the outer material, in particular in the region of the indentations of the lower fabric or of the lattice form of the lower fabric.

[0018] A too high body core temperature of a carrier of the insert clothing piece can be avoided by the fact that this is without lining. Owing to the embodiment of the outer material according to the invention, however, the insert article according to the invention has a similar insulating effect to conventional feed jackets.

Further features and advantages of the invention will become apparent from the following detailed description of an exemplary embodiment of the invention, with reference to the figures of the drawing showing the essential details of the invention, and from the claims. The features shown there are not necessarily to be understood to scale and are illustrated in such a way that the special features according to the invention can be made visible thereby. The various features can be implemented individually or in several combinations in variants of the invention.

[0020] Exemplary embodiments of the invention are illustrated in the schematic drawing and are explained in more detail in the following description.

[0021] FIG.

FIG. 1 shows a binding cartridge which shows the smallest repeat pattern of the fabric in the warp and weft direction; FIG.

2 shows a plan view of the rear side of an outer material, ie, the lower fabric.

FIG. 1 shows a bonding cartridge 1 of an outer material according to the invention. It shows the smallest repeating repeat of the fabric in the warp and weft direction. In the finished tissue, the binding cartridge describes a range of about 5 mm in width and about 6 mm in height. The warp and weft threads marked with a slash 2 form the fabric top side during the weaving process of the double fabric. The warp and weft yarns marked with an X 3 form the lattice on the fabric bottom during the weaving process. Circles 4 identify the binding points. They represent the connection of the lower fabric to the upper fabric. The warp threads of the lower fabric are thereby bound by the weft threads of the upper fabric into the upper fabric.

Claims

FIG. 2 shows a plan view of the underside of an outer material 10. In particular, the lower fabric 11 can be seen in a grid-like arrangement. The meshes of the mesh-like arrangement of the lower fabric 11 represent indentations 12, the bottom of the indentations 12 being formed by the upper fabric. This means that the upper fabric is seen through the meshes of the lattice. Air cushions can be formed in the indentations 12, which have an insulating effect. [0024] Both the upper fabric and the lower fabric 11 have aramid fibers which change, in particular contract, with the effect of heat. This is utilized, so that the grid structure is reinforced with heating and thus the indentations 12 are enlarged. Under heat, larger air cushions can thus form, Resulting in better thermal insulation. claims
