Description

[0001] The present invention relates to a neck protection collar formed from a band of non-woven fabric.

[0002] It is well known that during haircuts in hair salons, a neck collar is placed tightly around the customer's neck to protect them from falling hair, chemicals, and water. Neck collars made of crepe paper are particularly common, but these often cause an unpleasant itching sensation on the neck.

[0003] A neck ruff of the type mentioned above, designed in the form of a non-woven cuff, is described in publication DE 1 743 856 U. The known neck ruff is designed in the form of a band with perforations for detaching the band.

[0004] The described fleece is softer and more comfortable than crepe, but it does not absorb falling hair as well.

[0005] It is therefore the object of the present invention to provide a neck guard for hairdressing applications that feels comfortable on the neck and yet can effectively catch falling hair and thus protect a person well.

[0006] The task is solved by a neck protection collar formed from a band of nonwoven fabric, wherein the band has predetermined separation points, wherein the nonwoven fabric has a hole and / or trench structure over its entire surface and / or the nonwoven fabric has a roughened surface.

[0007] The hole or trench structure and / or the roughened surface create an uneven surface structure of the nonwoven fabric, which provides a larger surface area for hair to grip, allowing it to hook onto the fabric instead of sliding off and thus adhere particularly well.

[0008] The holes and / or grooves in the fleece lead to increased hair adhesion and drastically increase the mechanical anchoring of the hair in the material of the neck brace. Instead of gliding smoothly over the surface, the hair gets caught in the irregularities and edges of the holes and / or grooves. The uneven structure in the area of ​​a hole and / or groove also creates more friction, which promotes hair adhesion. Furthermore, the fleece material becomes more statically charged in the area of ​​a hole and / or groove, which attracts and holds the hair.

[0009] The roughened nonwoven surface features numerous protruding, fine fibers or fiber loops that form an irregular, three-dimensional structure. Hair also possesses a rough cuticle layer. When these two rough structures meet, they interlock, similar to Velcro. Furthermore, the roughened structure increases the effective contact area between the nonwoven and the hair. The fine fiber ends create increased friction, which holds the hair firmly to the surface of the nonwoven. Unlike smooth materials, where hair simply slides off, the open fibers of the roughened nonwoven do not provide a smooth surface on which the hair could lose its grip.

[0010] Preferably, no adhesive is applied to the surface of the neck protection collar. That is, the neck protection collar according to the invention has no adhesive surface for fixation. Instead, the neck protection collar according to the invention stays in place solely through the interlocking of the fibers of the nonwoven fabric.

[0011] Preferably, the nonwoven fabric is a parallel-laid nonwoven, and the neck protection collar is cut so that the predominantly parallel fibers of the parallel-laid nonwoven are oriented in the vertical direction of the neck protection collar. The vertical direction refers to the direction that, when the neck protection collar is attached to a person's neck, runs along the neck rather than around it. A parallel-laid nonwoven, also called a longitudinal-laid nonwoven, is characterized by the fact that its fibers are predominantly oriented in the machine direction during production, for example, by carding. This ensures that the nonwoven fibers, which are predominantly aligned vertically, can be easily pulled apart along the length of the web.This allows the neck guard to be stretched around the neck, so that the neck guard can be pre-made in a pre-made length, such as 58 cm, and yet still fit around different neck thicknesses.

[0012] However, in the neck protection collar according to the invention, a nonwoven fabric with transversely or crosswise laid nonwoven fibers, i.e., a so-called cross-laid nonwoven fabric, can also be used. In such a case, it is advantageous if the nonwoven fibers, which are on the one hand longitudinal fibers oriented in a longitudinal direction of the band and on the other hand transverse fibers oriented in a transverse direction of the band perpendicular to the longitudinal direction of the band, each have the same elongation.

[0013] Such a nonwoven fabric can be produced, for example, by appropriate calendering of the nonwoven and / or by a special, crosswise fiber placement, or by layering thin layers of nonwoven fabric with alternating fiber orientations. The uniform stretching creates a consistent grid structure within the nonwoven, ensuring consistently good adhesion of the hair across the entire neck guard.

[0014] In an advantageous further development of the neck protection collar according to the invention, it has an electrostatic feature. That is, in this embodiment of the invention, the nonwoven fabric is electrostatically charged. The electrostatic charge can be generated by roughening the surface of the nonwoven fabric, i.e., by mechanical friction, but can also be generated by exposing the nonwoven fabric to an electrostatic field. For the latter, a corona discharge, for example, can be used.

[0015] It has proven particularly advantageous if the nonwoven fabric is made of 100% polyester. Due to its synthetic properties, polyester is especially good at accumulating electrostatic charge.

[0016] However, the nonwoven fabric can also be made from another material instead of or in addition to polyester, such as polyester, polyethylene, polyamide, natural fibers or regenerated fibers, such as viscose or lyocell fibers.

[0017] In a further advantageous embodiment of the neck guard according to the invention, the nonwoven fabric is a hydroentangled nonwoven. This is particularly recommended if the nonwoven is a parallel-laid nonwoven. Hydroentanglement, also known as spunlacing or hydroentanglement, is an excellent method for structuring a nonwoven fabric so that hair can adhere to it more effectively. In hydroentanglement, fine jets of high-pressure water impinge on a loose fiber structure. This causes the fibers of the nonwoven to interlock tightly with one another. The water jets mechanically "hook" the fibers of the nonwoven without the use of a binder. Such a nonwoven offers a more open, rougher, and felt-like surface in which individual hairs can become mechanically entangled. Hydroentanglement creates voluminous, often three-dimensional structures that, compared to smooth, thermally bonded nonwovens, offer a much larger surface area for contact with hair.Furthermore, water jet bonded nonwovens are soft and flexible and have a structure that can envelop hair well instead of repelling it.

[0018] However, the nonwoven fabric can also be a nonwoven fabric bonded in another way, such as a needled nonwoven fabric, a meshed or sewn nonwoven fabric, a thermally bonded nonwoven fabric, or a nonwoven fabric bonded with binders.

[0019] It has proven particularly advantageous if the nonwoven fabric has a thickness or height of 1 to 2 mm. This results in a particularly comfortable feel when wearing the neck protection collar according to the invention. Furthermore, this reduces material usage, thus generating little waste when using the neck protection collar according to the invention.

[0020] The tape is typically, for example, an endless tape wound onto a roll or a stack of layers laid crosswise, from which required sections can be cut off for use as a neck protection collar. Cutting off these sections is facilitated if, according to one embodiment of the present invention, the tape has predetermined cutting points in the form of perforations spaced apart from one another and applied transversely to the tape's longitudinal direction.

[0021] Advantageous embodiments of the neck guard according to the invention are explained in more detail below with reference to the figures, wherein Fig. 1 shows a top view of an area of ​​a neck guard designed according to the invention with an enlarged image section; Fig. 2 a perspective view of an area of ​​the neck guard made of Fig. 1 shows an enlarged section of the image; Fig. Figure 3 schematically shows an embodiment of a neck protection collar designed according to the invention with parallel nonwoven fibers in a top view; and Fig. Figure 4 schematically shows an electrostatically charged fleece of an embodiment of the neck protection collar according to the invention in a perspective view.

[0022] The Fig. 1 and Fig. Figures 2 each show a top view of an area of ​​a neck guard 1 designed according to the invention, wherein in Fig. 1. An enlarged section of the image is also shown. Fig. Figure 2 shows an area of ​​the neck guard 1 in a perspective view.

[0023] The neck protection collar 1 consists of a non-woven fabric 2. The non-woven fabric 2 is in the form of a strip with a longitudinal direction L and a transverse direction Q. In the Fig. 1 and Fig. In the embodiment shown in Figure 2, the nonwoven fabric 2 consists of longitudinal fibers 3 aligned in the longitudinal direction L of the strip and transverse fibers 4 aligned in the transverse direction Q of the strip. The longitudinal fibers 3 and the transverse fibers 4 form a grid structure with holes 5.

[0024] In the Fig. 1 and Fig. In the embodiment shown in Figure 2, the nonwoven fabric 2 has a thickness d or fabric height of 1 to 2 mm. In this embodiment, the holes 5 extend through the entire thickness. In other embodiments of the present invention, not shown, grooves or depressions may be formed in the nonwoven fabric 2 instead of the holes 5, and these grooves or depressions may not extend through the entire thickness d of the nonwoven fabric 2.

[0025] In the Fig. In the embodiment shown in Figure 3, the nonwoven fabric 2' has predominantly parallel nonwoven fibers 3, some of which are shown schematically. That is, the nonwoven fibers of the nonwoven fabric 2' are predominantly aligned in a machine direction of a nonwoven laying device (not shown here). The neck guard 1 is cut such that the parallel nonwoven fibers 3 of the nonwoven fabric 2' extend in the vertical direction H of the neck guard 1. This results in high elasticity of the nonwoven fabric 2' in the longitudinal direction L of the web, which corresponds to the longitudinal direction of the neck guard 1, with which it is placed around a person's neck. Fig. The two arrows marked Z indicate the possible direction of pull. The fleece 2' can be pulled along these arrows and thus tightly around a neck. This causes the fleece fibers of fleece 2' to stand up, and the fleece 2' can then be fixed to itself without adhesive.

[0026] The transverse fibers 3 of the fleece 2' typically do not lie completely straight, but are slightly crimped in the fleece 2', resulting in a certain elasticity in the height direction H of the neck protection collar 1.

[0027] Trenches or depressions 5' are imprinted into the fleece 2'.

[0028] In the embodiment shown, the nonwoven fabric 2' has a basis weight of 50 g / m². 2 on.

[0029] Fig. Figure 4 schematically shows an electrostatically charged nonwoven fabric 2'' of an embodiment of the neck protection collar 1 according to the invention in a perspective view. The electrostatic charging is achieved by exposing the nonwoven fabric 2'' to an electrostatic field using an electrostatic charging device 7. Alternatively, or in addition, a surface 8 of the nonwoven fabric 2'' can be electrostatically charged by mechanical roughening. As a result of the electrostatic charge of the nonwoven fabric 2'', the hair 6 adheres particularly well to the nonwoven fabric 2''.

[0030] In the in the Fig. 1, Fig. 2, Fig. 3 to Fig. In the embodiments shown in 4, the nonwoven fabric 2, 2', 2'' consists of polyester, but in other embodiments of the present invention it can also be made of a different material or a mixture of materials.

[0031] Furthermore, the nonwoven fabric 2, 2', 2'' in the embodiments shown is water-jet bonded, i.e. it is a so-called water-jet bonded nonwoven fabric.

[0032] Hairs 6 adhere to the fleece 2, 2', 2'', which catch particularly on the holes 5 and are thus advantageously held on the fleece 2, 2', 2''. QUOTES INCLUDED IN THE DESCRIPTION
