Description
FIELD OF THE INVENTION
[0001] The present invention relates to dusters and methods for
making the cloths thereof, more particularly to a double-face
usable duster and the method for making the cleaning cloth thereof.
The double-face usable duster thereby made has a central portion
for cleaning irregular surfaces, and the inner layer and the outer
layer can be swapped to extend the durability of the double-face
usable duster.
BACKGROUND OF THE INVENTION
[0002] The dusters of the prior art are mainly feather dusters
suitable for cleaning surfaces of large areas and less efficient
for cleaning irregular surfaces. To clean irregular surfaces, a
cleaning cloth is held by a hand and applied to a surface. The hand
holding the cloth is easy to get stained, or the hand will wear a
glove, which is inconvenient to a user in either case. Therefore,
it is desirable to invent a duster for generally cleaning and
cleaning irregular surfaces.
SUMMARY OF THE INVENTION
[0003] The primary objective of the present invention is to provide
a double-face usable duster and the method for making the cleaning
cloth thereof for cleaning dust off various articles. The
double-face usable duster comprises a plurality of surface cleaning
layers each made of two non-woven fabrics through a hot-melt
process, during which process sleeves for retaining a handle arm
are formed on each of the surface cleaning layers. Each of the
sleeves has a closed end for preventing inserting the handle at a
wrong end. Between the surface cleaning layers, there situates a
central, electrostatic precipitating layer. The central layer is
made of hot melt nodal yarns provided with nodes. The hot melt
nodal yarns are a fabric interlaced by coarse and fine fibers
capable of being hot-melted, whereby the fibers will not entangled.
The central layer, the first surface cleaning layer and the second
surface cleaning layer are bound together by hot melting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] The various objects and advantages of the present invention
will be more readily understood from the following detailed
description when read in conjunction with the appended
drawings.
[0012] Referring to FIGS. 2, 3, 4 and 5, a double-face usable
duster according to the present invention comprises a first surface
cleaning layer 1, a second surface cleaning layer 9, a central
layer 8, and a handle 18. A plurality of sleeves 4, 12 are
respectively formed on the outer surfaces of the first surface
cleaning layer 1 and the second surface cleaning layer 9 when they
are made. A plurality of elongated weld lines 5, 13 are
respectively formed transverse to a selected longitudinal axis of
the first surface cleaning layer 1 and the second surface cleaning
layer 9.
[0013] The first surface cleaning layer 1 is combined by two layers
of non-woven fabric through a hot melt process. The first layer of
non-woven fabric is a needle-punched non-woven fabric with embossed
mesh 2, and the second layer of non-woven fabric is a smooth hot
melt non-woven fabric 3. Each of the sleeves 4 has a wider opening
and a closed narrow tail section 6, taking the form of an elongated
trapezoid. Thereby, a handle arm can be inserted and secured
therein, and the closed narrow tail section 6 can prevent inserting
a handle arm at a wrong end. Further, the outer portions of the
cleaning cloth made of the first surface cleaning layer 1 and the
second surface cleaning layer 9 are cut to form a multitude of
transverse strips 7 for providing a more effective cleaning
effect.
[0014] The central layer 8 is an electrostatic precipitating
portion sandwiched by the first surface cleaning layer 1 and the
second surface cleaning layer 9. The central layer 8 is made of hot
melt nodal yarns with a node density of 50 per inch. The hot melt
nodal yarns are a fabric interlaced by coarse and fine fibers
capable of being hot-melted, whereby the fibers will not entangled.
The central layer 8, the first surface cleaning layer 1 and the
second surface cleaning layer 9 are bound together by hot
melting.
[0015] The second surface cleaning layer 9 is combined by two
layers of non-woven fabric through a hot melt process. The first
layer of non-woven fabric is a needle-punched non-woven fabric with
embossed mesh 10, and the second layer of non-woven fabric is a
smooth hot melt non-woven fabric 11. Each of the sleeves 12 has a
wider opening and a closed narrow tail section 14, taking the form
of an elongated trapezoid. Thereby, a handle arm can be inserted
and secured therein, and the closed narrow tail section 14 can
prevent inserting a handle arm at a wrong end. Further, a multitude
of transverse embossments 15 are formed on the outer surface of the
second surface cleaning layer 9 for providing a more effective
cleaning effect.
[0016] A double-face usable duster 16 thereby formed is further
provided with two elongated openings 17 respectively along the
respective longitudinal axes ending at the elongated weld lines 5,
13. The elongated openings 17 have the effect of expanding the
cleaning surface of the double-face usable duster 16.
[0017] Referring to FIG. 7, a handle 18 is inserted into the
sleeves 4 on the first surface cleaning layer 1, forming a
double-face usable duster 16. The double-face usable duster 16 is
capable of cleaning a variety of articles, and, especially, the
elongated opening 17 is suitable for cleaning irregular surfaces.
When the cleaning cloth is dirty, the handle 18 is pulled out and
the cloth is flipped so that the second surface cleaning layer 9
becomes the outer layer. The handle 18 is reinserted into the
sleeves 12 on the second surface cleaning layer 9, as shown in FIG.
6.
[0018] Referring to FIGS. 1, 2, 3 and 4, the double-face usable
duster and the method for making the cleaning cloth thereof are
illustrated.
[0019] The method of making the cloth of the double-face usable
duster is illustrated in FIG. 1, which comprises the steps of
piling up a needle-punched non-woven fabric with embossed mesh 2
and a smooth hot melt non-woven fabric 3 to form a first surface
cleaning layer 1, being cut to form a multitude of transverse
strips 7, yarn setting and five-layer combining processing.
[0020] The central layer 8 is formed by the steps of processing
coarse fibers capable of being hot-melted into hot melt nodal
yarns, yarn setting and five-layer combining processing.
[0021] The second surface cleaning layer 9 is formed by the steps
of piling up a needle-punched non-woven fabric with embossed mesh
10 and a smooth hot melt non-woven fabric 11, cutting the second
surface cleaning layer 9 to form a multitude of transverse strips
15, yarn setting and five-layer combining processing.
[0022] The first surface cleaning layer 1, the central layer 8, and
the second surface cleaning layer 9 are then piled up and undergo
the steps of yarn setting, five-layer combining processing, and
five-layer hot stamping.
[0023] The first surface cleaning layer 1 and the second surface
cleaning layer 9 of the cleaning cloth are cut to form respective
elongated openings 17 extended along the longitudinal axis and
ended at the weld lines 5, 13. The cloth is then folded about its
longitudinal axis to form the final configuration of the
double-face usable duster.
[0024] The handle 18 is inserted into the sleeves 4 on the first
surface cleaning layer 1 to form the double-face usable duster 16,
as shown in FIG. 7, which can cleaning a plurality of articles. The
elongated opening 17 of the double-face usable duster 16 is
especially suitable for cleaning irregular surface of some
articles. When the cleaning cloth is dirty, the handle 18 is pulled
out and the cloth is flipped so that the second surface cleaning
layer 9 becomes the outer layer. The handle 18 is reinserted into
the sleeves 12 on the second surface cleaning layer 9, as shown in
FIG. 6.
[0025] The present invention is thus described, and it will be
obvious that the same may be varied in many ways. Such variations
are not to be regarded as a departure from the spirit and scope of
the present invention, and all such modifications as would be
obvious to one skilled in the art are intended to be included
within the scope of the following claims.
