HUT76692A - Cleaning cloth or apparatus with fringes - Google Patents

Abstract

The fringes contain ring spun yarns. While having the same fullness, absorbency and cleaning power, these cleaning cloths or apparatus, for example wiping covers, may be up to 25 % lighter. Fluff formation is considerably reduced.

BACKGROUND OF THE INVENTION The present invention relates to a cleaning cloth or cleaning article having loose-tipped fringes (5). The loose-ended fringes (5) are formed as opposed twisted threads of annular braided yarns. Cleaning cloth is a cloth that can be washed in a washing machine. The fringes (5) of the cleaning cloth or detergent have a length of 3.5 to 5.5 cm and consist of 65% polyester and 35% cotton.

BACKGROUND OF THE INVENTION 1. Field of the Invention

For example, the cleaning cloth may be a wiping device for a support portion of a floor wiping device, as described, for example, in German Patent Application DE 38 23 456 C1. Before cleaning, the attachment is tensioned on the support. Since the pad is not permanently connected to the cleaning device, it can be washed separately, for example in a washing machine. The invention also relates to a cleaning device with tassels permanently connected thereto, such as hand-wipes. The only thing that matters is that the cleaning tool or the cleaning fabric has loose-tipped fringes.

The cleaning fabrics and the cleaning means permanently or releasably connected thereto have different cleaning properties according to the design of the fabrics. Fringes, loops or tassels have a large surface area and therefore have a high absorbency. This is particularly true for fringes, whose loose ends additionally increase the effective surface. In the case of fringes, spontaneous suction capacity is greatest.

In addition to these advantages, however, the disadvantages of the fringes are the high slip resistance on the floor, the instability of the fringe tips, and the strong build up of lichen on the surface to be cleaned and, in the case of washable linen, in the washing machine.

In order to overcome these disadvantages, it is necessary to choose cleaning fabrics without loose yarn ends, such as loops. The disadvantages of low absorbency and low absorbency should then be noted.

It is an object of the present invention to significantly reduce the formation of clowns in loose-tufted cleaning fabrics or detergents without reducing suction capacity and cleaning performance.

According to the invention, this object is solved by the fact that the fringes comprise annular braided yarns.

• · · ·

- 3 For two reasons, leaching is much lower than in conventional cleaning textiles. On the one hand, the parallel positioning of all the individual fibers in the ring braided yarn, which is described in more detail below, causes the individual fibers to be detached from the yarn less frequently than in the prior art. On the other hand, cleaning fabrics can contain up to 25% less fiber than normal cleaning fabrics with the same suction capacity and cleaning performance. This also results in lower bohol formation.

In contrast, known solutions employ rotor yarns for making fringes because they are cheaper. In rotor spinning, each fiber is led to a rotor that rotates at high speed. Inbound fibers in the rotor gather on the inner wall. It is formed there and at the same time the yarn is made by twisting. Unlike a ring spinner, the rotating spinner can move further and does not have to be stopped when the fully wrapped roll is removed. The rotor spinning process thus enables the production of yarn inexpensively and in large quantities.

However, the individual strands of the spun yarn are unordered and are not parallel. The tangle of fibers in the rotor yarn, and in particular the individual strands of yarns, called strands, running transversely to the longitudinal direction of the yarn, interferes with and limits the suction and swelling capacity of the fibers.

Unlike the rotor yarn, the individual strands of the ring braided yarn are primarily parallel. The resulting foil is solidified by true twisting using a running ring. The result is a neat, parallel filament yarn that does not prevent the fibers from swelling themselves. The consequence is fluffy fiber and particularly high suction capacity. Ring braided wipes can be up to 25% lighter as we have stated, yet have the same fullness, suction capacity and cleaning performance as heavier rotor wipes.

Particularly preferred are the fringes, which are formed as opposed twisted yarns from annular braided yarns. Since all the individual yarns of the ring braid are opposite to the individual yarns of the other yarn, the loose yarn ends automatically close at the loose yarn ends. In contrast, in the case of fringes made of rotor braided yarns, the ends of the yarn are unwound.

It has been found in experiments that loose tassels, which are formed as threads made of annular braided yarns, are especially closed when washed and that frequent washing is effective against separation of the tufts. Therefore, in a further embodiment of the invention, it is proposed that the wiping cloth suitable for washing the cleaning cloth in a washing machine, in particular a floor wiping device, be provided.

We also recommend that the fringes contain 65% polyester and 35% cotton. The length of the fringes may be 0.5 to 10 cm, preferably 3.5 to 5.5 cm.

The arrangement of the fringes can be different and depends on the requirements of the top. Conditions with only a tassel-wrapped wreath have the highest cleaning performance but are cumbersome due to the increased frictional resistance. The floor is facilitated by a wrap-around wreath with loose fringes on the outside and loops on the inside. In any case, the cleaning performance is slightly lower. Alternatively, loops and tassels can be alternately placed in the flange of the top. However, the invention is not limited to a particular arrangement of the fringes or loops in the circumferential flange of the wipe.

Our invention by way of example! Embodiment of the present invention is described in more detail with the help of our figure.

On the upper side of the fabric cover 2 there are disposed pockets 3 with ribs 4 for sliding into the ends of the non-illustrated sheet-shaped support portion of the wiping device.

At the edge of the topsheet 2 is a circumferential wreath of fringes 5. In the present case, it is a complete fringe. The fringes have a length of 4 cm and consist of 65% polyester and 35% cotton.
