Definitions

• the invention relates to protective leg clothing, in particular protective socks, against chemical and / or biological pollutants.
• Lower leg protective clothing is known in the civilian field, in particular in the medical field.
• EP 0 705 543 B1 describes lower leg protective clothing which, in order to avoid injury or recurrence of an injury in sports or training activities, is said to produce a bandaging effect.
• Waterproof, breathable socks are also known (see e.g. EP 0 386 144 Bl).
• EP 1 269 877 describes a protective suit as overall for protection against chemical pollutants.
• a disadvantage of known protective suits against chemical and / or biological pollutants in the military field is that they only reach up to the ankle and the feet are therefore not protected. Overboots made of 100% butyl are used to protect the feet. However, a disadvantage is that the boots can only be activated if the 'soldier has attracted the suit. However, since the protective suits are usually very stiff, putting on the boot is relatively difficult. The well-known overboots also have no breathability and are relatively bulky and large. Because they are separate from the protective suits, there is also a risk that they will be lost.
• the present invention is therefore based on the object of providing under-leg protective clothing, in particular protective socks, which avoids the disadvantages mentioned above, in particular which is very comfortable to wear and can be worn like a conventional sock or stocking.
• a lower leg protective clothing in particular a protective sock which has several layers, with an outer leg part and a laminate arranged in the interior of the outer leg part, which has a flexible, windproof and water-deflecting membrane which forms the outside of the laminate and which has at least one barrier for biological Forms pollutants, a carbon layer arranged under the membrane, in which carbon is present in fiber or particle form, and has an inner textile fabric layer.
• the lower leg protective clothing according to the invention also offers high wearing comfort. It is very flexible and can be worn like a "normal" stocking or socks.
• the lower leg protection according to the invention put on clothing before putting on the suit, which means that a person wearing a protective suit is put on more quickly in the event of an operation and also has better freedom of movement.
• the membrane is made breathable according to the invention, the wearing comfort can be improved even more.
• the outer leg part can be an outer sock made of wool, cotton, silk, polyester, polypropylene, polyamide, polyacrylic, modifications or mixtures thereof if they are designed as socks. Protection against chemical and / or biological pollutants is achieved by the laminate according to the invention. In this way, the windproofness of the membrane prevents wind from entering the carbon layer underneath and thus impairing its effectiveness. Due to the watertightness, wetting or penetration of liquid chemicals into the carbon layer is also prevented, which would also lead to an impairment of effectiveness.
• the membrane acts on a corresponding one. Also designed as a filter against pollutants.
• hydrophilic membranes e.g. There is no microporosity in polyester, polyether, polyester copolymer and the like, which creates a barrier against biological pollutants. However, water vapor molecules can still pass through, but water cannot.
• the carbon layer underneath can be made thinner without impairing its effectiveness. This increases the wearing comfort considerably because the heat-accumulating carbon layer is thinner.
• membranes are e.g. materials based on cellophane, polyvinyl alcohol, polyacrylamides, polyurethanes and mixtures thereof.
• microporous membranes e.g. Polytetrafluoroethylene
• breathability is achieved despite being windproof and watertight.
• the carbon layer can have a woven or knitted fabric with 100% activated fibers or also activated carbon spheres which have been applied to a carrier material.
• the wearing comfort is improved even more if, in addition to the outer leg part, an inner leg part on the inside, i.e. the side of the laminate facing the carrier is arranged.
• the inner leg part can be made from synthetic fibers, such as e.g. Polypropylene, polyamide, polyester, modifications and mixtures thereof.
• a textile fabric can be provided as the textile fabric layer, which forms a mechanical protective layer for the carbon layer.
• the membrane On the outside, in addition to its protective effect against pollutants, the membrane also forms a mechanical protective layer for the fiber layer.
• Figure 1 is a side view of the lower leg protective clothing according to the invention as protective socks.
• FIG. 2 shows a rear view of the protective sock according to FIG. 1;
• Fig. 7 is a greatly enlarged cross section through a protective sock in another structure.
• the lower leg protective clothing according to the invention is described below using a protective sock.
• other lower leg protective clothing such as Stockings, possible in the configuration according to the invention.
• the protective socks shown in FIGS. 1 and 2 have an outer sock 1 as the outer leg part.
• a laminate 2 is arranged in the interior of the outer sock 1, the structure of which is described in more detail below with reference to FIGS. 6 and 7.
• An inner sock 3 is arranged on the inside as the end of the protective sock as an inner leg part.
• the three layers consisting of outer socks 1, laminate 2 and inner socks 3, are connected to one another and are put on together as a protective sock.
• the connection between the three layers can e.g. by sewing and / or gluing.
• the sewing can e.g. in the area of the upper ends of the three layers and additionally in the heel and toe area, e.g. by means of flags.
• the inner sock 3 can optionally be made hydrophilic. At the seams, the inner socks 3 should be made of chem, fluffy spun yarn, so that pressure points on the foot are prevented.
• the inner socks 3 can be placed at the upper end over the laminate 2 and the outer socks 1 in the form of a cuff, as shown in dashed lines in FIGS. 1 and 2 is.
• moisture absorbed in this way can be transported to the outside and can evaporate there.
• Outer socks 1 and inner socks 2 can be made from several cut parts. Of course, outer socks 1 and inner socks 3 can also be woven or knitted without a seam.
• the laminate 2 can be produced from three cut parts, as can be seen from FIGS. 3 to 5 - FIG. 3 shows the cut part for a shaft 4 of the laminate.
• Fig. 4 shows the cut part for an upper part 5
• Fig. 5 shows a cut part for a sole 6 of the laminate - the same or similar applies to the outer socks 1 if this is also made from cut parts.
• FIG. 6 shows in a greatly enlarged cross section the structure of the protective sock from the three layers, namely the outer sock 1, the laminate 2 and the inner sock 3.
• FIG. 6 also shows the structure of the laminate 2, which consists of three layers exists.
• the outer side, ie the side of the laminate 2 facing away from the carrier, is formed by a membrane 7. Under the membrane 7, ie on the side facing the support, there is a carbon layer 8 and a textile fabric layer 9 is provided as the inner layer.
• the membrane 7, the carbon layer 8 and the textile fabric layer 9 are connected to one another in a known manner by a lamination process.
• This can e.g. by means of a point-by-point lamination, adhesive being introduced point by point between the layers to be connected and then the layers being connected to one another during a pass through pressure rollers.
• the lamination process can be carried out with or without heating.
• Fig. 7 shows basically the same structure as the embodiment of the protective sock according to Fig. 6. The only difference is that in this case the inner socks 3 are missing, so that the textile layer 9 of the laminate 2, which in this case then will form hydrophilic, rests on the foot of the wearer.
• the membrane 7 is designed to be flexible so that stretching in both the transverse and longitudinal directions is possible and tearing is avoided.
• the active carbon layer 8 can be produced in fiber form from a knitted or woven fabric.
• active carbon fibers it is known to burn viscose fibers or a viscose fabric or knitted fabric in a controlled manner and to control the combustion process in such a way that activated carbon is formed with extremely fine pores, which then produce the filter effect.
• the thickness of the carbon layer 8 can be between 0.2 to 1.0 mm, preferably between 0.4 to 0.8 mm.
• Advantageous active surfaces of the carbon layer 8 are in a range from 800 to 2,000 m 2 / g, preferably between 1,000 to 1,200 m 2 / g.
