Abstract

The invention relates to a piece of textile underwear (10; 10 ') which has an inside (20) facing the body of a wearer and an outside (30) opposite this inside (20). At least one area of the undergarment (10) has at least two layers, in that an inner layer (41) lies on the inside (20) of the undergarment (10) and is made of a liquid-absorbent textile material, while an outer layer (40) on the outside ( 30) of the undergarment (10) and is formed from a 3D knitted fabric.

Description

The invention relates to a textile underwear item according to the preamble of claim 1, which has an inside facing the body of a wearer and an outside opposite this inside.

If textile clothing is worn during sports or other strenuous activities, the wearer may develop sweat, which can be uncomfortable for various reasons. The garment absorbs sweat from the wearer's skin, which can result in it being visible on the outside. If the sweat does not evaporate quickly enough, the garment becomes very moist, which can be uncomfortable when wearing it and dangerous due to the risk of catching a cold.

A large number of functional textiles have therefore become known in the field of clothing, which are intended to transport sweat as quickly as possible from the skin of a wearer, ie from the inside of a clothing item, to the outside so that it evaporates there. Furthermore, items of clothing have been proposed which have a two-layer structure, a 3D network structure being provided on the inside of the item of clothing in order to provide ventilation for the skin. A 3D network structure is intended to prevent contact between the skin of a wearer and another outer textile layer. For example, the JP 3046374 such a piece of clothing.

In addition, it is common to wear underwear under an outer garment, such as a shirt, so that sweat does not get directly into the outer garment but is initially absorbed by the underwear. If there is a particularly large amount of sweat, the sweat can still get into the outer clothing, which affects its appearance. Especially in activities such as dancing, where men's shirts are worn, this can lead to that the sweat on the shirt is visible and does not evaporate quickly enough.

Proceeding from this, it is therefore the object of the invention to provide a textile item of clothing with which the impairment of the appearance of an outer clothing item by welding a wearer can be reduced.

According to the invention, this object is achieved by a textile underwear item according to independent claim 1. Advantageous further developments of the undergarment result from subclaims 2-13.

It should be pointed out that the features listed individually in the claims can be combined with one another in any technically meaningful way and show further refinements of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.

The textile undergarment according to the invention has an inside facing the body of a wearer and an outside lying opposite this inside. At least one area of the undergarment is made at least in two layers, in that an inner layer lies on the inside of the undergarment and is formed from a liquid-absorbent textile material, while an outer layer lies on the outside of the undergarment and is formed from a 3D knitwear, which is the transition from Inhibits fluid from the inner layer to the outside of the undergarment. The item of underwear is preferably an item of underwear for the upper body, at least having a back part and two arm openings.

Such an undergarment has the advantage when worn under an outer garment that the inner layer absorbs sweat well from the skin. Due to the outer 3D knitted fabric, however, the moist / wet inner layer has no direct contact with the outer clothing item, so that the sweat does not reach the outer clothing item. The inner layer soaks up sweat and sticks possibly on the skin. However, the outer layer made of 3D knitwear creates a barrier between the moist inner layer and the outer garment. The outer garment remains so sweat-free that its appearance is not affected. Even if sweat penetrates all the way to the outer garment, this does not take place over a large area, but only selectively. This affects the appearance of the outer garment less than large welding surfaces.

The textile underwear item according to the invention thus has effective perspiration protection. The invention turns away from solutions in which sweat is to be transported as quickly as possible from the inside to the outside of a piece of clothing. It also turns away from solutions in which a 3D knitted fabric is placed between the skin of a wearer and another textile layer in order to keep sweat away from the textile layer. Rather, the invention provides an undergarment with an inner layer that is deliberately designed to absorb sweat as well as possible and to keep it there. The inner layer is allowed to soak up sweat and may create an uncomfortable feeling on the skin, since the main aim of the invention is to keep sweat away from an outer garment worn over the underwear. The invention therefore also includes an arrangement of an undergarment according to one embodiment of the invention and an outer garment, the undergarment being arranged under the outer garment such that the outer layer of the undergarment lies between the inner layer and the outer garment and can be contacted by the outer garment.

In the area provided according to the invention with an inner layer and 3D knitwear, the underwear piece is designed at least in two layers. If additional layers are provided, the arrangement is at least selected so that the 3D knitted fabric always forms the outer layer. For example, more than one inner layer can be provided to absorb the sweat. On the outside, however, the underwear piece has the 3D knitted fabric in order to keep the inner layers and the outer clothing at a distance from one another.

The materials and the structure of the inner layer and the 3D knitted fabric are selected accordingly to fulfill the functions mentioned. For example, the inner layer is formed by a textile made of natural fibers and / or synthetic fibers and has an overall hydrophilic property. For natural fibers, for example, fibers made of cotton, wool, bamboo, etc. come into consideration. Textiles made from such natural fibers absorb sweat particularly well. In the case of synthetic fibers or man-made fibers, fibers made from natural or synthetic polymers come into consideration. Fibers made from inorganic substances can also be used. However, mixtures of natural and synthetic fibers are also possible. The textile material of the inner layer is formed into a flexible and compliant fabric or knitted fabric that does not hinder the movement of the wearer. The inner layer, for example, has a thickness of up to 2 mm and is made relatively thin.

The 3D knitted fabric of the outer layer is preferably formed from fibers with hydrophobic properties, in particular from fibers made from natural polymers, synthetic polymers and / or from inorganic substances. For example, the fibers are made of polyester, polyacrylic, polypropylene, polyamide and / or elastane, and mixtures of different types of fibers can also be used. When processed appropriately, the 3D knitted fabric absorbs and transports liquid such as sweat only poorly. This can be achieved in various ways, whereby a 3D knitted fabric in the sense of the present invention is to be understood as a flat knitted fabric which has, however, been expanded into the third dimension. The knitted fabric is knitted or knitted, although combinations are also possible. Furthermore, it is not a homogeneous knitwear with a certain thickness, but it is inhomogeneous and comprises a special spacing structure between two outer bearing surfaces, which inhibits the transfer of liquid. Air in particular inhibits the transition.

For example, the 3D knitted fabric of the outer layer is formed from a spacer fabric or knitted fabric that is formed by two flat knitted fabric or knitted fabric layers that are spaced apart by an intermediate spacing structure. The spacing structure is formed, for example, by a multiplicity of spacing threads (pile threads), which the two knitted layers connect to one another connect. Such knitted spacer fabrics or knitted spacer fabrics are therefore knitted fabrics which have been expanded to include the third dimension. They are typically referred to as 3D mesh. The spacing structure between the two flat knitted or knitted layers has the effect that the transfer of liquid (sweat) from one knitted or knitted layer to another is inhibited. Furthermore, the fibers of the knitted or knitted layers are preferably chosen so that they have hydrophobic properties.

The thickness of such a 3D knitted fabric is determined by the thickness of the knitted or knitted layers and the length of the pile threads. The aim is to have a sufficiently large distance between the inner layer and the outside of the 3D knitted fabric, the 3D knitted fabric also not being so thick that the outer layer is strikingly visible under an outer garment and / or impairs the movement of the wearer. For example, the thickness of the outer layer is between 0.5 mm and 5 mm, in particular between 0.5 mm and 2 mm. Even if the inner knitted or knitted layer of the outer layer absorbs sweat through contact with the inner layer, it is difficult for the outer threads to knit, which in turn can have contact with an outer garment, via the pile threads.

Furthermore, openings are preferably formed in the knitted or knitted layers, the size of which is selected appropriately. The size can in particular be selected so that the 3D knitted fabric has the desired flexibility, but has a contact surface towards the inner layer that is as small as possible in order to keep sweat absorption as low as possible. These are not openings that inevitably form in stitches of a knitwear, but the knitted fabric or knitted fabric forms the edge of larger openings through several stitches. For example, the width of an opening is more than one millimeter.

In another embodiment of the invention, the 3D knitted fabric of the outer layer is formed by a knitted fabric or knitted fabric with two outer layer surfaces which are spaced apart from one another. The outer layer surfaces are the opposite surfaces of the outer layer in the direction of their main extent. Here a knitted fabric or knitted fabric forms a lattice structure that has a three-dimensional dimension between the two outer bearing surfaces. A mesh surface with openings without meshes is also formed on at least one outer surface. The lattice structure formed by a knitted fabric or knitted fabric is thus not only three-dimensional, as a result of which it forms a spacing structure, but it also forms a surface of meshes on one side of the outer layer, which is interrupted by openings. The openings without meshes have an essentially round or polygonal shape, for example hexagonal or diamond-shaped openings being used. These are also not openings which inevitably form in stitches of a knitted fabric, but the knitted fabric or knitted fabric forms the edge of larger openings through several stitches. For example, the width of an opening is more than one millimeter.

The outer layer can consist exclusively of such a three-dimensional lattice structure, or the lattice structure is formed on a knitted or knitted layer which serves as the basis for the lattice structure. In the latter case, the outer layer is arranged within the undergarment in such a way that the lattice structure either points towards the inner layer or forms the outside of the outer layer. The grid structure has the effect that the transfer of liquid (sweat) through the outer layer is inhibited, since it creates a distance between the outside and the inner layer of the undergarment. Furthermore, the fibers of this 3D knitted fabric are preferably also selected so that they have hydrophobic properties. In addition, the openings in the mesh surface on at least one outer layer surface have the effect that the contact surface with an outer garment and / or the inner layer is reduced.

The thickness of such a 3D knitted fabric is determined by the thickness of the lattice structure and the optional knitted or knitted layer to form a base for the lattice structure. For example, the thickness of the outer layer is between 0.5 mm and 5 mm, in particular between 0.5 mm and 2 mm.

The invention can be implemented in various types of undergarments. However, it is particularly advantageous for underwear items for the upper body, ie for undershirts. These have at least one back part and two arm openings, and can be designed completely or partially at least in two layers with a spacer fabric. A front part and sleeves can also be provided. Since a sweat often forms on the back of a wearer, in one embodiment of the invention at least one back part is made in two layers. Other areas such as arm openings or sleeves can also be formed in two layers, or this only applies to the back part. The single-layer areas of the undergarment are preferably made of the same textile material as the inner layer in the two-layer area.

The underwear piece does not necessarily have to be designed like a classic undershirt with front and back. Rather, a piece of underwear with only one back part and two arm openings is sufficient. For example, this is the case with an undergarment that is in the form of a vest or a bolero that is open at the front.

The 3D knitted fabric is preferably firmly connected to the inner layer. However, it can also be a detachable connection, for example via push buttons, hooks, Velcro strips, etc. A fixed connection can also be implemented in different ways. The connection is preferably not made over the entire 3D knitted fabric, but only locally. In this way, the outer layer remains movable to a certain degree with respect to the inner layer. The combination of inner layer and 3D knitted fabric is therefore not a prefabricated layer structure, but only two interconnected individual textiles. For example, the outer layer is connected to the inner layer by sewing, gluing or other suitable types of connection for textiles. Sewing is preferably selected.

In one embodiment of the invention it is provided that the outer layer is connected to the inner layer at a connecting line which runs all the way around the outer layer. The 3D knitted fabric is then connected to the inner layer, for example, exclusively at the outer edge of the outer layer. However, further connection points can also be provided within the surface of the outer layer be. The outer layer can also be continuously connected to the inner layer along this circumferential connecting line. However, there can also be several local connection points which are arranged on a circumferential connection line. If sewing is selected as the type of connection, it can be, for example, a circumferential seam with which the edge of the spacer fabric is connected to the inner layer.

Both the inner layer and the 3D knitted fabric preferably have a skin color or are white, so that, for example, under a white shirt, they are hardly noticeable at least in terms of color.

Of the Fig. 1 is a front view of a first embodiment of an undergarment 10 according to the invention, which is an undershirt that is designed as a vest or bolero open at the front. It has a back part 11 on which two short sleeves 12 and 13 are formed. The sleeves 12, 13 can be sewn onto the back part 11 as individual parts, or the back part 11 and sleeves 12, 13 are formed in one piece from a continuous textile which forms the sleeves 12, 13 by means of cuts and corresponding seams. This underwear item 10 is made in two layers in at least one area, the two-layer being achieved by an inner layer and an outer layer. In particular, only the back part 11 is constructed in two layers, but this can optionally also be the case for the sleeves 12, 13. The undergarment 10 is thus a total of a textile trained, which in a two-layer area by adding an outer layer to an inner layer.

Fig. 2 shows such an undergarment 10 in a rear view while Figure 3A a side view and Figure 3B a top view of the neck area of an undergarment according to Fig. 1 demonstrate. The sleeves 12, 13 each form an arm opening 14 and 15 and a neckline 16 is formed in the upper region of the back part. The two-ply in the area of the back part 11 is achieved by an outer layer 40, the edge of which is attached to the back part 11. This is preferably done via a circumferential stitching 50. The expansion and attachment of the outer layer 40 via a stitching 50 is the rear view of FIG Fig. 2 refer to. However, this configuration is only to be understood as an example, and in particular the shape of the outer layer can also be chosen differently.

Fig. 4 and Fig. 5 show a front view and a rear view of a second embodiment of an undergarment 10 'according to the invention. This is designed more as a vest and less as a bolero, so that in addition to the back part 11 and two sleeves 12, 13, two narrow front sides 17 and 18 are also provided. An outer layer 40 sewn on via a stitching 50 is again the rear view of FIG Fig. 5 It can be seen that the outer layer 40 has a different cut in this embodiment than in the embodiment of FIG Fig. 1 . The cut can therefore be adapted to the design of the respective undershirt.

The outer layer 40 is arranged on the outside of the respective undergarment. This two-ply is the schematic representation of the Fig. 6 can be seen, which shows a section of a two-layer area such as the back part. The underwear piece which is two-ply in this area has an inner side 20 which points towards the wearer of the underwear piece. In contrast, the outside 30 of the undergarment is. An inner layer 41 lies on the inner side 20 and an outer layer 40 on the outer side 30. The inner layer 41 is formed by a liquid-absorbent textile, the sweat from the skin of a wearer can record and save. The outer layer 40, however, is formed by a 3D knitted fabric.

In one embodiment of the invention, the 3D knitted fabric 40 is formed by a spacer fabric (3D mesh). The exemplary structure of such a 3D mesh 40 is shown in the schematic illustration of FIG Fig. 7 shown. It is formed by two knitted layers 42 and 43 which are spaced apart by a spacing structure 44. This spacing structure 44 is formed by a plurality of pile threads which are connected to the knitted layers 42, 43. As an alternative to knitted layers, knitted layers can also be used.

Fig. 10 shows a three-dimensional view of such a spacer fabric 40. From this it can be seen that openings 45 are formed in the knitted layers 42 and 43, which are preferably aligned with openings in the respective other knitted layer. However, the openings 45 can also be arranged offset to one another. Furthermore, the 3D mesh can also have other forms of knitted fabric.

The inner layer 41 and the outer layer 40 can be connected to one another in different ways in the two-layer area, in particular this does not take place over the entire area. For example, shows Fig. 8 in a schematic representation of how an outer layer 40 is connected to an inner layer 41 via two stitchings 50 and 51. There can thus be a distance between the two layers 40, 41 and it is not a prefabricated layer structure. Rather, two individual textiles are suitably connected to one another, which is preferably done at the edge of the outer layer 40. Optionally, further connection points can be provided within the surface of the outer layer 40.

Fig. 9 shows a schematic representation of an undergarment 10 between the body 60 of a wearer and an outer garment 70. The absorbent inner layer 41 of the undergarment 10 points towards the body 60 and can absorb sweat from there. The outer layer 40 with the 3D knitted fabric, on the other hand, points to the outer clothing 70 and thus creates a barrier between the moist inner layer 41 and the outer clothing 70.

Of the Fig. 11 A second embodiment of a 3D knitted fabric 40 'can be seen in a schematic side view. It is a knitted fabric or knitted fabric with two outer bearing surfaces 48 and 49, which in the Fig. 11 are only shown in dashed lines, since they are not flat, continuous surfaces. The two outer bearing surfaces 48, 49 are spaced apart from one another, and the knitted fabric or knitted fabric forms a lattice structure 47 'which has a three-dimensional dimension between the two outer bearing surfaces 48, 49. Furthermore, the lattice structure 47 'forms a mesh surface with openings without meshes on at least one outer surface. In the embodiment of the Fig. 11 For example, the lattice structure 47 ′ forms a mesh surface 46 on the outer bearing surface 48, in which a plurality of openings 45 are located. The lattice structure 47 'is also formed on a base layer 47, which forms the outer layer surface 49 and also consists of knitted fabric or knitted fabric. The three-dimensional lattice structure 47 'creates a distance between the base layer 47 and the outer surface 48 which inhibits the transition from liquid, ie sweat. The lattice structure 47 'can be directed toward the inner layer of the undergarment, or it forms the outside of the undergarment.

In the top view of the Fig. 12 lies the outer layer surface 48 so that the mesh surface 46 with the openings 45 can be seen. The openings 45 here have a substantially hexagonal shape, but they can also have a different shape. The underlying base layer 47 can be seen in the openings 45. In a further embodiment of the invention, a 3D knitted fabric 40 "does not have a base layer, but rather consists only of a three-dimensional lattice structure made of knitted fabric or knitted fabric with several openings. For example, shows Fig. 13 analogous to Fig. 12 such a lattice structure without a base layer. The openings 45 are therefore continuous.
