Abstract

A three-dimensional cleaning textile comprising a textile cleaning back (1) having a front side (2) and a rear side (3) and at least one pile (4) of at least one pile yarn (5) which is non-detachably connected to the cleaning back (1) and protrudes beyond the front side (2).

Description

Three-dimensional cleaning textile and preparation method thereof

Technical Field

The invention relates to a three-dimensional cleaning textile and a preparation method thereof.

Background

Three-dimensional cleaning textiles and methods for their preparation are well known. Wherein the cleaning textile comprises a woven cleaning back having a front side and a rear side, wherein the front side is designed for cleaning a surface to be cleaned. The method for producing three-dimensional textile fabrics is tufting, for example. Tufting is suitable for producing looped or velvet fabrics.

In addition, plush threads as fabrics or knits and corresponding production methods are known. Plush has generally a very soft hand. Is characterized by upright fluff, which can be provided with different heights by additional equipment. The plush fabric is essentially very resistant to pulling due to the firm embedding of the nap in the back.

In the case of knitting plush, the extra threads are tied into a common knitted fabric, forming small loops on the surface.

Disclosure of Invention

The main object of the present invention is to show a three-dimensional cleaning textile with a high/low structure that can be produced, for example, from the same fibers or yarns. The cleaning textile should have consistently good use characteristics, in particular consistently good cleaning results, over a long period of use, and the cleaning textile should be simple, inexpensive and reliable in the preparation process. The cleaning textile should be able to move with as little friction as possible over the surface to be cleaned, have good dirt-absorbing properties and good water-absorbing and/or water-removing properties.

According to the invention, this object is achieved by the features of claims 1 and 14. The dependent claims referring to claim 1 relate to advantageous embodiments of the cleaning textile product, and the dependent claims referring to claim 14 relate to advantageous modified embodiments of the method.

To achieve this object, a three-dimensional cleaning textile is provided, comprising a textile cleaning back having a front side and a rear side, and at least one pile consisting of at least one pile yarn, which is non-detachably connected to the cleaning back and protrudes beyond the front side. It is advantageous here if the front side of the cleaning textile to be protected has different pile heights, which are adapted to the respective given conditions of the respective application. The cleaning back may, for example, have a uniform basic structure which projects beyond the pile formed by the at least one pile yarn. By having a high/low structure on the front side and by utilizing this high/low structure to move over the surface to be cleaned, friction is reduced and dirt pick-up is improved during the intended use of the cleaning textile.

The pile yarns protruding beyond the front side are subjected to a relatively higher pressure load than the cleaning back itself during the intended use of the cleaning textile. Because of the relatively high surface pressure of the pile yarns, stubborn dirt can also be easily removed from the surface to be cleaned and subsequently collected in areas which are not so high relative to the pile formed by the pile yarns.

The cleaning back may be formed of fabric. It is particularly advantageous if the fabric is formed from plush. Plush fabrics have many advantages, particularly when used as cleaning textiles. The plush fabric has good and uniform water absorbency and dewatering properties and good cleaning performance by effectively removing dirt from the surface to be cleaned. The plush has low friction when moving over the surface to be cleaned, can effectively absorb and retain small particle dirt, and has good chemical resistance.

In contrast, a cleaning back made of a planar fabric would be less suitable for use as a cleaning textile, since it has, for example, a lower cleaning performance. Also, the water absorbency and dewatering properties of the planar fabrics are markedly poorer.

The plush may comprise at least a first pile height and a second pile height, wherein the second pile height is greater than the first pile height. If such plush is used, the front side of the cleaning back already has two mutually different pile heights, by means of which the use characteristics of the cleaning textile can be adapted well to the nature and/or soiling of the surface to be cleaned.

Additionally or alternatively, it is possible for the plush to have regions of higher density and lower density arranged adjacent to one another. According to another embodiment, the plush may be interrupted by a plush-free region.

DE 10 2015 014 069.8 discloses a cleaning textile comprising a cleaning side with a cleaning surface which is delimited by edges of the peripheral side, wherein the cleaning surface has a lower pile density in the middle than the edge side, seen in a wiping direction transverse to the cleaning textile.

The preparation of the cleaning textile according to the invention can be significantly simplified by the plush being interrupted by the non-plush area. With this construction it is clearly visible visually in which areas the fleece is connected to the cleaning back.

According to an advantageous embodiment, it can be provided that only areas of lower density or areas of no pile are connected to the pile yarns. This arrangement has the advantage that the material requirements are significantly reduced in areas of lower density or in areas of no pile and that clean textiles can be produced at low cost.

It is furthermore advantageous that the weight of the cleaning textile is lower, due to the areas of lower density or due to the non-pile areas, compared to a cleaning textile without these areas. The cleaning textiles are typically washed in a washing machine, according to the intended use of the cleaning textile. By cleaning textiles with areas of lower density or with areas of no pile, more of such cleaning textiles can be washed per unit of wash load, which is a worth emphasizing advantage in terms of reduced wash costs and environmental protection.

Although the first and second pile heights may be different from each other, the difference in length between the pile heights can only be relatively small due to the production process.

Since the pile yarns are connected to the cleaning back, it is also possible to prepare a high/low structure having a large pile height difference. There is also the possibility of creating a high/low structure from the same fibers/yarns.

According to a first embodiment, it can be provided that the fleece forms loop-shaped knots on the front side. The loop-shaped pile knots have the following advantages: the sliding friction is reduced when the cleaning textile is moved over the surface to be cleaned. Thus, the user can clean quickly and with little effort. Furthermore, loop-shaped knots absorb loose dirt, such as hair, particularly well.

According to a second embodiment, it can be provided that the pile yarns protrude beyond the front side in cut pile. In this case, it is advantageous to achieve a particularly deep cleaning effect by using such a cleaning textile. This is important, for example, for thoroughly cleaning the structured back. Furthermore, the corners and corner regions can be easily cleaned, as the relatively long cut pile prevents mechanically overuse/destruction of the lower adjacent regions. Furthermore, the open-topped non-endless cut pile largely prevents the cleaning textile from becoming entangled with its surroundings and thus being damaged during its use.

The pile knots or cut piles have a third pile height greater than the second pile height. As already described above, the sliding friction is reduced when using the cleaning textile in such a way that the cleaning textile has good dirt-absorbing capacity and is particularly well suited for ergonomic work due to its bulky design.

The fleece may pass through the cleaning back between the front side and the rear side and be connected to the cleaning back on the rear side by a shackle portion. By means of the hook sleeve portion it is ensured that even when cleaning the surface to be cleaned, the pile yarn is not undesirably pulled out of the cleaning back when a normal tensile load is applied to the pile yarn.

The shackle portion may be formed by a woven, knotted latch of the fleece with the cleaning back. This knotted latch of the pile yarn occurs during the preparation of the cleaning textile.

The rear side and the hook sleeve portion may be non-removably covered by a pile yarn fixing backing. This pile yarn fixing backing protects the pile yarns covering the rear side of the cleaning back from mechanical overloads.

According to a first embodiment, it can be provided that the fleece fixing backing is formed by a coating, by means of which the fleece is additionally fixed to the hook sleeve of the cleaning back. Such a coating may be formed, for example, by a rubber coating.

According to a second embodiment, the pile yarn fixing backing may be formed of a separately produced protective fabric.

Such a protective fabric preferably has the rear side dimension, covers the rear side and the shackle portion over the entire surface, and is non-detachably connected to the cleaning back.

The protective fabric may be composed of polypropylene (PP) or Polyester (PES), for example.

The protective fabric and the cleaning back are preferably sewn to each other. By means of this stitching a durable connection is created, the fleece is irremovably held in its position in the cleaning back and the cleaning textile overall has consistently good use characteristics during long-term use.

The invention further relates to a method for producing a three-dimensional cleaning textile, wherein in a first method step, pile yarns are connected to a cleaning back by tufting. Tufting is well known per se. The working principle is the same as that of the sewing machine. The needle introduces knitting wool into the clean back. Before the needle is pulled back again from the cleaning back, the introduced pile yarn is held by the gripper, so that a loop-shaped pile knot is produced on the front side of the cleaning back.

Depending on whether the pile yarn is to form loop-shaped knots or to protrude beyond the front side with cut pile, the loops either remain unchanged or are cut open with a knife, so that the previously described cut pile is subsequently produced.

In a second method step, the rear side and the hook sleeve portion can be coated with a coating.

However, if the additional fastening part should not be formed by a coating, but by a separately produced protective fabric, the rear side and the hook sleeve part are covered with the protective fabric in the second method step. The protective fabric may preferably be sewn to the rear side of the cleaning back.

Drawings

Four embodiments of the cleaning textile according to the invention are explained in more detail below with reference to fig. 1 and 4.

These show details of the three-dimensional cleaning textile, respectively.

In fig. 1 a cleaning textile is shown, wherein the pile yarns form loop-shaped pile knots on the front side;

in fig. 2 a cleaning textile is shown, which differs from the cleaning textile in fig. 1 in that the pile yarns protrude beyond the front side in cut pile;

a cleaning textile having regions of higher density and lower density is shown in fig. 3; and

in fig. 4 a cleaning textile is shown, wherein the plush is interrupted by a non-plush area.

Detailed Description

In fig. 1 and 4, respectively, an embodiment of a three-dimensional cleaning textile is shown, comprising a textile cleaning back 1 having a front side 2 and a rear side 3. In the embodiment shown here, the cleaning back 1 is formed from a plush fabric.

In the exemplary embodiment shown here, the plush has two different pile heights 6, 7, namely a first pile height 6 and a second pile height 7, wherein the second pile height 7 is greater than the first pile height 6.

In fig. 1, the fleece 5 forms 2 loop-shaped knots 8 on the front side.

In fig. 2, a cleaning textile is shown with cut pile 9, which protrudes beyond the front side 2.

As can be clearly seen in fig. 1 and 2, the three pile heights 6, 7, 10 differ significantly from one another. The second pile height 7 is higher than the first pile height 6 and the third pile height 10 is higher than the second pile height 7.

In both embodiments, the pile yarns 5 are held on the rear side 3 of the cleaning back 1 by the hook sleeve portion 11 and are thereby prevented from accidentally disengaging from the cleaning back during the intended use of the cleaning textile. The shackle portion 11 is realized by a knot-shaped latch.

In fig. 1, a fleece-yarn fixing backing 12 is provided, which is non-detachably connected to the rear side 3. In this embodiment, the pile yarn fixing backing 12 is formed by a coating 16.

In contrast, in fig. 2, the fleece-retaining backing 12 is formed by a protective fabric 17, which has the dimensions of the rear side 3, the rear side 3 and the hook sleeve 11 being covered over the entire surface and being sewn to the cleaning back 1.

In fig. 3, the cleaning back, which is also made of plush as the aforementioned cleaning back, has areas of higher density 13 and lower density 14. In the areas of lower density 14, loop-shaped knots 8 are arranged, or these areas are protruded beyond by cut pile 9.

Fig. 4 differs from fig. 3 in that a non-pile area 15 is provided instead of the lower density area 14, wherein the non-pile area 15 is surrounded by plush. In these non-pile areas 15 pile yarns 5 are arranged, which protrude beyond the front side 2.

The lower density region 14 or the no-pile region 15 can be easily detected visually.

It can thus be seen immediately which areas have to be tufted with pile yarns and which areas are subsequently covered with loop-shaped pile knots 8 or cut piles 9.
