Cleaning clo~h for Cas~enin~ ~o a cleaning-cloth holder
The invention relates to a cie~ning c_ot~ for
~astening ~o a cleaning-cioth holder, i~ the form of a
sheet-like textil2 st~AUcture.
C12~ning cioths of this kind ~re used
p~rticularly as floor-wipln~ cloths, dust mops, etc~,
~epenc:~ing on ehe t~?2 o:t cleaning requiret~ n this
case, th~ cleanln~ cloths ~re -astened ~o a cloth
holde~, spe~fically by means of a re}e~sable
fastenlng, in order ~o ma~e 1~ possib1e to wring out,
cleanse and also exc~2nae ~he cleaning cloth. The
cleaning cloths or ~he type mentioned are the~efore
ready-made and possess lateral fold-round ed~es, in~o
which thç en~s of a cloth holder baseplate can be
pu~he~, with the re~ult th~t the cle~ning cloth can be
fa~tened rel~asa~ly ~o the clo~h holdex The need _or a
ready-made product i~ cost-intensive and resul~ in ~n
~5 increased consump,ion of cl~aning cloth. Furthermore,
it is complicated and therefore time-consuming to
rasten the cleaning cloth to the cleaning-clo~h holder.
In gene~al, in this case, the cleaning cloth has to ~e
held in the hands, thus al-~o leadin~ to an undesirable
so~ g of the hands.
The object of ~he inven~ion i~, therefore, to
pro~ide a cleaning cloth
which, without the
~ualit~ of a cleaning cloth being impaired, is designed
~i in su~h a wa~ t~a~ an be fastened to ~A cleaning-
cloth holder and released from this again simply and
quickly.
This obje~ is achieved by means of ~he

Pile or plush fabric with a basic fabric and
with a pile cover bound into th~ fronL side o~ the
basic f~briç are particularly pre~erred as the ~heet-

which ma~ possikly llkewise project on the fr~n~ side
of the basic fabric ~re concealed by the pile co~er ~nd
therefore do no~ impede the cleaning operation.

The loops of the loop yarn may be ~ormed by a
spun-fi~re, mult;~ilament o~ mo~oril~ment thread. The
advant~ge of pun-fibre and multif lament threads is
that ~e loops consist of a fibre bundle, in which the
barbs of a bar~ed covexing are securely anchored in a
similar way to a .leecy layer. This applies

to Cl~im 7. Loops consistin~ o~ monofilaments have the
advantage of ~ high load-b-aring cap~city.
The basic fabri~ may be a knitted or wo~en
fabric, depending on the i~tended use ~nd the type of
cleaning. ~n the case or a woven fabric with crossed
warp and weft thre~ds, the loop yarn is preferably used
for the weft threads, and e~ch weft thread or every
second to ~ourth weft thread may co~sis~ of the loop
yarn. This ensures that the entire back of a cleaning

cloth is covered with a hook-in laver. ~here is no need
for the barbed covering on the cleaning-clo~h holder to
~e positioned in relation to the back or ~he clean~g
cloth. The clean.ng-cloth holder can be pressed with
its ~a~bed ~oYJeri-lg ontc the ~k of ~he ~leaning cloth

Figures 1 and 2 shows a first exemplary embodiment of a
cleaning cloth 1 for fastening to a cleaning-cloth holder 2, in the form
of a sheet-like textile structure with a basic fabric 3 formed by at
least one thread system. A preferred sheet-like textile structure is a
flat or pile or plush fabric which may be woven, knitted or tufted.
In the cleaning cloth illustrated in Figures 1 and 2, the
sheet-like textile structure is designed as a pile or plush fabric,
specifically with a basic fabric 3 into which is bound a pile cover 4
covering a front side of the basic fabric 3.
In this case, the basic fabric 3 may be a stitched fabric or a
woven fabric, the thread or threads of at least one thread system of the
basic fabric 3 being formed at least partially by a loop yarn which
forms loops 7. The loops 7 extend outwardly from a thread core 12 and a
plurality of loops 7 are provided along the thread core 12. Preferably
the loops 7 are fixed on the core close to each other. The loops 7 can
have the same sizes or different sizes. Loops 7 of the worked-in loop
yarn appear on a rear side 6 of the basic fabric 3 and provide this rear
side 6 with a layer of projecting loops 7. The number of loops 7 arran-
ged on the rear side 6 depends, in particular, on the number of loop
yarn threads worked into the basic fabric 3.
The loops 7 formed by the loop yarn are suitable for coming
into adhesive engagement (in the manner of a touch-and-close fastening)
with barbs 8 of a barbed covering on a baseplate 9 of the cleaning-cloth
holder 2. There is therefore provision for the rear side 6 of the basic
fabric 3 to have, at least along a part region, a hook-on covering 11
which is formed by the loops 7 and which, together with a barbed cover-
ing, forms an adhesive fastening (touch-and-close fastening).
In the exemplary embodiment described here, the basic fabric 3
is a woven fabric with a plurality of crossed warp threads 10 and weft
threads 5 (see Figure 2). The pile cover 4 covering the front side of
the basic fabric 3 is bound into the basic fabric 3. By contrast, the
rear side 6 of the basic fabric 3 remains pile-free. The weft threads 5
consist of the loop yarn, whilst the warp threads 10 consist of a plain
yarn. The weft threads 5 worked in as loop yarn appear on the rear side
CA 02206730 1997-06-03
6 of the basic fabric purely because the weft threads 5 are crossed
alternately with the warp threads 10 by virtue of a fabric weave.
In this case, simple weaves, such as, for example, the cloth
weave, are preferred as a type of weave. In the case of even-sided
weaves of this kind, although the weft threads 5 consisting of the loop
yarn may also form loops on the front side of the basic fabric 3 (see
Figure 2), these loops are covered by the pile cover 4. Non-even-sided
weaves are also suitable, and these may be used to ensure that the weft
threads consisting of the loop yarn predominate on the rear side 6 of
the basic fabric 3.
In order to obtain as high a number of loops 7 as possible,
all the weft threads 5 of the basic fabric 3 of a cleaning cloth 1 may
consist of the loop yarn. Alternatively, only every second to fourth
weft thread 5 may consist of a loop yarn. Furthermore, the weft threads
5 preferably have a higher yarn strength than the warp threads 10 and
are consequently thicker than the warp threads 10 which are preferably
fine.
Furthermore, alternatively, either only the warp threads or
the weft threads and the warp threads 10 may consist of a loop yarn.
Moreover, a uniform distribution of the threads of a thread system,
which consist of a loop yarn, over a width and/or length of the basic
fabric 3 is preferred.
A bouclé yarn or loop twist with a yarn strength of preferably
Nm 0.5 to Nm 20 is used as a loop yarn. The loops 7 are anchored on a
thread core 12, being defined by a basic thread. An additional thread of
the loop yarn is provided on the thread core 12, the said additional
thread producing the loops 7, preferably consists of a plastic material
and may be a spun-fibre, multifilament or monofilament thread. If the
loops are formed by a spun-fibre thread, its fibre strength is prefer-
ably around 0.7 to 30 den. The basic thread can be made from the same
materials. The basic thread and the additional thread are worked to-
gether to achieve a loop yarn with loops 7 which can be distributed
along the core 12 regularly and wherein the loops 7 have substantially
the same sizes (see Figure 1 and 2). Alternatively the loops 7 can be
CA 02206730 1997-06-03
distributed along the core 12 irregularly and in different sizes as
shown in the embodiment of Figures 3 and 4. The statements made above
concerning Figure 1 and 2 otherwise apply accordingly to the embodiment
of Figure 3 and 4.
The pile cover 4 is formed by a pile which is bound into the
basic fabric 3 and which may be designed as a cut pile or loop pile. The
pile naps are bound in preferably according to the W-weave. The pile
length, pile density and pile material may be selected according to the
intended use.
To consolidate the cleaning cloth 1, the rear side 6 of the
basic fabric 3 may be impregnated with a hardening coating, hardening
being completed preferably under the effect of heat.
According to a further exemplary embodiment which is not
illustrated, the sheet-like textile structure may be a flat fabric. In
the case of a flat fabric, the loop yarn is preferably worked in in such
a way that it does not appear or appears only slightly on the top side
or front side of the basic fabric which constitutes the effective
cleaning surface. Such a flat fabric is, in particular, a woven flat
fabric with a plurality of thread systems in a plurality of tiers. The
statements made above otherwise apply accordingly.
Although the invention has been described in connection with
what is presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention is not limited to
the disclosed embodiments, but rather, is intended to cover various
modifications and equivalent arrangements included within the spirit and
scope of the appended claims.
