Abstract

A three-dimensional cleaning textile comprises a textile cleaning back (1) having a front side (2) and a rear side (3) and at least one pile (4) consisting 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 making the same are well known. Wherein the cleaning textile comprises a textile cleaning back having a front side and a back side, wherein the front side is designed for cleaning a surface to be cleaned. A method for producing three-dimensional textile fabrics is for example tufting. Tufting is suitable for producing terry or velour fabrics.

Furthermore, plush materials as fabrics or knits and corresponding production methods are known. Plush fabrics generally have a very soft feel. Characterized by upright pile, which can be brought to different heights by additional equipment. The plush fabric is basically very resistant to pulling, since the pile is firmly embedded in the back.

In the case of knitted 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 having a high/low structure, which can be produced for example from the same fibers or yarns. The cleaning textiles should have consistently good use properties, in particular consistently good cleaning results, over a long period of use, and the cleaning textiles should be simple, inexpensive and reliable in the production process. The cleaning textile should be able to move over the surface to be cleaned with as little friction as possible, have good dirt pick-up and good water absorption and/or dewatering properties.

According to the invention, this object is achieved by the features of

claims

1 and 14. The dependent claims dependent on claim 1 relate to advantageous embodiments of the cleaning of textiles and the dependent claims dependent on claim 14 relate to advantageous further embodiments of the method.

In order 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 with the cleaning back and protrudes beyond the front side. It is advantageous here for the front side of the cleaning textile to be protected to have different pile heights, which are adapted to the respective given conditions of the respective application scenario. The cleaning back can, for example, have a uniform basic structure which is extended by a pile formed by at least one pile yarn. By having a high/low structure at the front side and by means of this moving over the surface to be cleaned, friction is reduced and dirt pick-up is improved during the intended use of the cleaning textile.

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. Because of the relatively high surface pressure of the pile yarns, tough soiling can also be easily removed from the surface to be cleaned and subsequently collected in regions that are not as 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 of plush material. Plush fabrics have many advantages, particularly when used as cleaning textiles. The plush fabric has good and uniform water absorption and dewatering properties and has good cleaning performance by effectively removing dirt on the surface to be cleaned. Plush fabric has low friction when moving over the surface to be cleaned, is effective in absorbing and retaining small particle soils, and has good chemical resistance.

In contrast to this, a cleaning back consisting of a flat fabric would be less suitable for use as a cleaning textile, since the cleaning back has, for example, a lower cleaning performance. Also, the water absorbency and dewatering of the flat woven fabric are significantly poor.

The plush may include 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 a plush fabric is used, the front side of the cleaning back already has two pile heights which differ from one another and 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 and lower density arranged adjacent one another. According to another embodiment, the plush may be interrupted by a non-plush area.

DE 102015014069.8 discloses a cleaning textile having a cleaning side with a cleaning surface which is delimited by peripheral edges, wherein the cleaning surface has a lower pile density in the middle than at the edge sides, viewed transversely to the wiping direction of the cleaning textile.

The production of the cleaning textile according to the invention can be significantly simplified by the interruption of the plush area by the non-plush area. With this construction it is visually clear in which areas the pile yarn is connected to the cleaning backing.

According to an advantageous embodiment, it can be provided that only areas of lower density or non-pile areas are connected to the pile yarn. This arrangement has the advantage that the material requirements are significantly reduced in the lower density or non-pile areas and the cleaning textile can be produced at low cost.

It is furthermore advantageous that the weight of the cleaning textile is lower compared to a cleaning textile without these areas, due to the lower density areas or due to the non-pile areas. The cleaning textiles are typically laundered in a washing machine, depending on the intended use of the cleaning textiles. By having areas of lower density or cleaning textiles with lint-free areas, more of such cleaning textiles can be washed per washing load, which is an advantage worth emphasizing in terms of reduced washing costs and environmental protection.

Although the first and second pile heights may differ from one another, the difference in length between the pile heights may only be relatively small due to manufacturing process concerns.

Due to the pile yarn being attached to the clean back, it is also possible to produce high/low structures with a large pile height difference. There is also the possibility of creating high/low structures from the same fibers/yarns.

According to a first embodiment, provision can be made for the pile yarns to form an annular pile knot on the front side. The annular pile knot has the following advantages: the sliding friction is reduced as the cleaning textile is moved over the surface to be cleaned. Thus, the user can clean quickly and with little effort. In addition, the looped pile holds loose dirt, such as hair, particularly well.

According to a second embodiment, provision can be made for the pile yarns to project beyond the front side in cut pile. It is advantageous here to achieve a particularly deep cleaning effect by using such a cleaning textile. This is important, for example, for thorough cleaning of the structured back. Furthermore, the corners and angular areas can be easily cleaned, since the relatively long cut pile prevents mechanically excessive use/damage of the lower adjacent areas. Furthermore, the open-topped non-loop cut pile largely prevents the cleaning textile from becoming entangled with its surroundings during its use and thus being damaged.

The pile or cut pile has 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 that the cleaning textile has a good dirt absorption capacity and is particularly well suited for ergonomic working due to its bulky design.

The pile yarn can be passed through the cleaning back between the front side and the rear side and is connected to the cleaning back on the rear side by means of a shackle portion. By means of the hook and loop portion it is ensured that, even when cleaning the surface to be cleaned, the pile yarn is not pulled out undesirably from the cleaning back when normal tensile loads act on the pile yarn.

The shackle portion may be formed by a pile yarn and a woven, knot-like latch that cleans the back. This knot-like latching of the pile yarns occurs during the production of the cleaning textile.

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

According to a first embodiment, it can be provided that the pile yarn fastening backing is formed by a coating by means of which the pile yarns are additionally fastened with the loops of the cleaning back. Such a coating may be formed, for example, by a rubber coating.

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

Such a protective fabric preferably has the dimensions of the rear side, 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 made of polypropylene (PP) or Polyester (PES), for example.

The protective fabric and the cleaning back are preferably sewn to each other. By this stitching a permanent connection is produced, the pile yarns are held in their position in the cleaning back undetachably and the cleaning textile as a whole has consistently good use properties over a long period of use.

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

Depending on whether the pile yarn is to form loop-shaped pile knots or to protrude with cut pile beyond the front side, 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 and loop part are covered with the protective fabric in a second method step. The protective fabric may preferably be sewn onto the rear side of the cleaning back.

Drawings

Four embodiments of cleaning textiles 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 in which pile yarns form looped pile knots on the front side;

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

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

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

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 back 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, the second pile height 7 being greater than the first pile height 6.

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

In fig. 2, a cleaning textile with cut pile 9 is shown, 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 yarn 5 is held on the rear side 3 of the cleaning back 1 by the shackle portion 11 and is thereby prevented from accidentally falling out of 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 pile yarn fastening backing 12 is provided, which is non-detachably connected to the rear side 3. In this embodiment, the pile yarn anchor backing 12 is formed from a coating 16.

In contrast, in fig. 2, the pile yarn fixing backing 12 is formed by a protective fabric 17 having the dimensions of the rear side 3, the rear side 3 and the shackle portion 11 being covered over the entire surface and sewn to the cleaning back 1.

In fig. 3, the cleaning back, which is also composed of plush like the previously described cleaning back, has areas of higher density 13 and lower density 14. In the regions of lower density 14, looped pile knots 8 are arranged, or these regions are raised by cut pile 9.

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

The lower density regions 14 or the non-pile regions 15 can be easily detected visually.

It can be seen immediately from this which areas have to be tufted with pile yarns and which areas are subsequently covered by endless loops 8 or cut pile 9.
