In the description of the following embodiments, the same reference numerals are attached to the same construction requirement and explanations thereof are omitted or simplified.

[First Realization]

In Fig. 1 to Fig. 5, the first embodiment of a cleaning article and a manufacturing method thereof of the present invention are shown. Fig. 1 is a diagram showing the cleaning article manufacturing process and is an exploded perspective view of the insert forming process; Figs. 2A and 2B are diagrams showing the manufacturing process of the cleaning article of the present invention and are exploded perspective views of the brush piece forming process; Fig. 3 is a diagram showing the cleaning article manufacturing process and is an exploded perspective view of the bonding process; Fig. 4 is a perspective view of the cleaning article; and Figs. 5A and 5B are cross-sectional views taken along the XX direction in Fig. 4. The first embodiment is explained below according to the manufacturing process of the cleaning article.

<Insert Part Forming Process>

First, as shown in Fig. 1, the retention sheet 1 and the base material sheet 2 are spread and heat sealed on the two lines, the bond line 7 'and the bond line 6 'which is located approximately in the center thereof, and a connecting body 15 is formed. Through this, two insert spaces 13 and 13 are formed between the retention sheet 1 and the base material sheet 2 by the two lines, the insert sealing line 7 and the insert sealing line 6a. inserted part. The retention sheet 1 and the base material sheet 2 are preferably made of heat sealable material such as non-woven fabric, for example. Heat sealing for the formation of seal lines in the present invention includes, in addition to heat sealing through the simple pressure of a heated sealing bar, methods such as impulse sealing, high frequency sealing and ultrasonic sealing.

Next, a strip piece 8 is formed by cutting the joined body 15 into strips from both sides, and an insert 16 is formed. The strip piece does not have to be formed in the insert according to the present invention. Furthermore, the insert forming method according to the present invention is not limited to the insert 16, above, but the insert 16 must be attached to a brush piece, and the space for inserting the insert must be formed by a couple of blades.

<Brush Part Forming Process>

As shown in Fig. 2A, a first fiber bundle 3a made of tow fiber, a second fiber bundle 3b made of tow fiber, a third fiber bundle 3c made of tow fiber, a fourth fiber bundle 3c made of tow fiber are formed. 3d of fibers made of tow fiber and a 5 sheet of strips with a multitude of strips that are laminated in sequential order.

ES 2 425 222 T3

Then, the five sheets are joined by heat sealing on the seal line 6 'and a brush piece 17 is formed. In other words, in this brush piece 17, all the layers are integrated by a brush seal line 6b.

In the present invention, the brush seal line, above, is not limited to one seal line, and for example, as shown in Fig. 2B, it may comprise a multitude of seal lines such as the three lines 6b. and brush seal 7b. In addition, the lines can be zigzag lines or curved lines rather than straight lines and can also be a dotted seal.

By providing a multitude of sealing lines as in the figure. 2B, it is made difficult for the fibers to move between the multitude of sealing lines 6b-7b-7b, and the maintenance of flatness is facilitated. Therefore, the joining of the joined part is facilitated in the joining process, and the joining can be performed accurately. Furthermore, by providing a fiber part that does not move easily in the central section due to the separation between the multitude of sealing lines 7b-6b-7b, the fiber parts (fiber part having the brush effect) that they are in a loose state on the outside of the seal line 7B (on both sides) they are properly separated from each other. Therefore, this effectively prevents the fiber pieces on both sides from tangling together and the brushing effect is reduced.

Although the conventionally known tow fiber can be used for the fiber bundles 3a to 3d and is not particularly limited thereto, it is preferable that the material is heat sealable. Also, the number of fiber bundle layers is not limited and can be one layer. The strip sheet 5 is preferably made of heat-sealable material such as a non-woven fabric, for example, as is the case for the aforementioned retention sheet 1 and the base material sheet 2. According to the present invention, the material that forms the brush piece 17 is not limited to a combination of tow fiber bundles and shredded sheets and may be only tow fiber bundles or only shredded sheets. Furthermore, the material composing the brush piece 17 must be a fibrous material, and may be a different material than the aforementioned of tow fiber bundles and / or sheets cut into strips, such as non-woven material, knitted material or rope type material. As "strip-cut sheets", strip sheets are preferably implemented in which several grooves are formed in the sheets made of fibrous material from the outer edge towards the direction of the center line of the sheet.

<Union Process>

The anterior insert 16 and the brush part 17 are joined by a hot melt mass 20. More specifically, the hot melt mass 20 is applied in approximately the central section of the first fiber bundle 3a of the brush part. 17, preferably between the sealing lines 7 and 7 of the insert and are joined to obtain the main cleaning part 11 (hereinafter, the cleaning article according to the present invention).

Although the joining elements for the insert 16 and the brush piece 17 must be a known adhesive and are not particularly limited, the known hot melt mass is particularly preferred. Furthermore, the adhesive can be applied on the side of the insert 16, on the side of the brush part 17, or on both sides. Furthermore, the location of the application is not particularly limited, but should be in a location where the insert 16 and the brush piece 17 can be joined.

<Operation>

In the main cleaning part 11 obtained by the above manufacturing method, the two insert spaces 13 and 13 are formed between the retention sheet 1 and the base material sheet 2, as shown in Fig.

Four. In addition, handle 12 is formed from inserts 12a and 12a that are spaced in two from base piece 12b and extend approximately parallel. The cleaning tool 10 can be used when inserting this insert 12a into the insert spaces 13 and 13.

In this memory, cHerein as shown in Fig. 5A, in this cleaning tool 10, the brush part 17 and the insert 16 of the main cleaning part 11 are joined by the hot melt mass 20, and there are no sealing lines joining all the layers. Therefore, as shown in Fig. 5b, even when the insertion seal line 6a and the brush part seal line 6b are misaligned, the insert gap 13 is not affected. Therefore, in the joining process, an effect is achieved where the precision of mechanical positioning does not really have to be taken into consideration.

The cleaning article comprises a brush piece in which the tow fiber bundle is laminated and a strip sheet in which multiple grooves are formed from the outer edge of a sheet formed of fibrous material and the area in the vicinity of the center line of the layered body is integrated by a multitude of heat seal lines and an insert is formed by heat sealing a pair of sheets, wherein an insertion space for insertion allows engagement and removal of a handle. The insert is located on the strip sheet and the strip sheet of the brush piece and the insert are attached by adhesive.

In the insert forming process, as shown in Fig. 6, the insert 36 having two insert gaps 33 is formed by laminating the retention sheet 31 and the base material sheet 32 ​​and sealing by heat in two lines, the 7 'junction line and the 6' junction line which is located approximately in the central part, with which the process is completed.

On the other hand, in the process of forming the brush piece, as shown in Fig. 7, the sheet 5 of strips are laminated in sequential order in which multiple pieces of strips are formed, a first bundle 3a of fibers made of tow fibers, a second fiber bundle 3b made of tow fibers, a third fiber bundle 3c made of tow fibers, a fourth fiber bundle 3d made of tow fibers and another sheet 5 of strips in which multiple pieces of strips are formed. Then, the brush piece 37 is formed by joining the six sheets by heat sealing at the joint line 6 '. In other words, this brush piece 37 has the strip sheet 5 in the upper section and all the layers are integrated by the sealing line 6b of the brush piece.

Furthermore, in the bonding process, as shown in Fig. 8, the main cleaning piece 35 is obtained by applying a hot melt mass 20 to the strip sheet 5 of the brush piece 37 and bonding the piece 37 brush and insert 36. By applying the hot melt mass 20 onto a strip sheet 5 that is softer than the fiber bundle in this way, the brush piece 37 and insert 36 can be more securely joined.
