- FIG. 4 is a schematic view for explaining the method and system for producing the cleaning member 1 .
- the system 100 which is shown in FIG. 4 is used to work the method for producing the cleaning member 1 and produce the cleaning member 1 .
- the method of production of the cleaning member 1 includes the following Step 1 and Step 2 .
- Step 1 Step of opening fiber bundles to step of conveying them
- Step 2 Step of using fiber bundles to produce multilayer web and cutting out cleaning member 1 from multilayer web
- Step 1 will be explained.
- Step 1 includes the following Step 1 a and Step 1 b.
- Step 1 a Step of opening first fiber bundle F 1 to fourth fiber bundle F 4
- Step 1 b Step of conveying first fiber bundle F 1 to fourth fiber bundle F 4
- Step 1 includes Step 1 a , but the presence or absence of Step 1 a may be suitably selected in accordance with the type of the fiber bundles used.
- Step 1 a is omitted may be mentioned.
- the fiber bundles are comprised of noncrimped fibers, Step 1 a may be omitted.
- Step 1 a will be explained with reference to the example of the step of opening the first fiber bundle F 1 , but the steps of opening the other fiber bundles are similarly performed.
- the first fiber bundle F 1 which is comprised of crimped fibers is continuously pulled out from a storage container (not shown) and sent to first nip rolls 102 a and 102 b which rotate by a certain peripheral velocity V 1 . After passing the first nip rolls 102 a and 102 b , the first fiber bundle F 1 passes through a plurality of tension rolls 104 and is sent to second nip rolls 106 a and 106 b which rotate by a peripheral velocity V 2 .
- the peripheral velocity V 2 of the second nip rolls 106 a and 106 b is faster than the peripheral velocity V 1 of the first nip rolls 102 a and 102 b . Due to this difference in peripheral velocities, between the first nip rolls 102 a and 102 b and the second nip rolls 106 a and 106 b , the first fiber bundle F 1 is given tension. As a result, the first fiber bundle F 1 is opened.
- the tension rolls 104 are formed from solid steel and are adjusted in mass so that a considerable degree of force is required to rotate them. Therefore, while the first fiber bundle F 1 is turning the tension rolls 104 and advancing from the first nip rolls 102 a and 102 b toward the second nip rolls 106 a and 106 b , the speed of movement of the first fiber bundle F 1 does not rapidly increase.
- the tension rolls 104 are arranged to be able to gradually open the first fiber bundle F 1 by the distance between the first nip rolls 102 a and 102 b and the second nip rolls 106 a and 106 b becoming longer.
- the first fiber bundle F 1 which passes through the second nip rolls 106 a and 106 b passes through an air feeder 108 and is sent to third nip rolls 112 a and 112 b which rotate by a peripheral velocity V 3 .
- the peripheral velocity V 3 of the third nip rolls 112 a and 112 b is slower than the peripheral velocity V 2 of the second nip rolls 106 a and 106 b . Due to this difference in peripheral velocities, between the second nip rolls 106 a and 106 b and the third nip rolls 112 a and 112 b , the tension of the first fiber bundle F 1 is eased. As a result, the first fiber bundle F 1 is further opened and the width of the first fiber bundle F 1 is expanded.
- the first fiber bundle F 1 which is sent to the second nip rolls 106 a and 106 b to the third nip rolls 112 a and 112 b is blown with air from the air feeder 108 . As a result, the first fiber bundle F 1 is further opened.
- the opening method may be suitably changed.
- an embodiment in which either the operation of imparting and easing tension and the operation of blowing air is used may be mentioned.
- an embodiment in which the operation of imparting and easing tension and the operation of blowing air plus use of another opening method may be mentioned.
- first to third nip rolls are used, but the number of nip rolls can be suitably changed.
- an embodiment in which other nip rolls are used in addition to the first to third nip rolls may be mentioned.
- the oil tank 114 contains an oil.
- the oil which is contained in the oil tank 114 is a dust catching oil which has the action of promoting adsorption of dust, dirt, etc. (for example, oil mainly comprised of liquid paraffin).
- Step 1 b the conveyance step for the first fiber bundle F 1 will be explained as an example, but the conveyance step for other fiber bundles are similarly performed.
- the first fiber bundle F 1 does not pass the nip rolls, tension rolls, etc. until the merging part 132 , so the first fiber bundle F 1 is not given a stronger tension from the first nip rolls 102 a and 102 b than the tension between the third nip rolls 112 a and 112 b.
- first fiber bundle F 1 advances to the merging part 132 .
- second to fourth fiber bundles F 2 to F 4 respectively advance to the merging parts 136 , 138 , and 140 .
- Step 2 includes the following Step 2 a to Step 2 c.
- Step 2 a Step of laying fiber bundle after Step 1 b over other member (in the present embodiment, belt-shaped nonwoven fabric) to form multilayer web
- Step 2 b Step of fastening fiber contained in multilayer web with other members
- Step 2 c Step of cutting out individual cleaning members 1 from multilayer web
- Step 2 a will be explained.
- the other member which is overlaid with fiber bundles after Step 1 b is a belt-shaped nonwoven fabric 121 , 123 , or 151 .
- a belt-shaped nonwoven fabric 121 , 123 , or 151 As another embodiment, an embodiment in which one or two of these belt-shaped nonwoven fabrics is overlaid with fiber bundles after passing through Step 1 b may be mentioned.

- In the
Aspect 1, in the step of conveying the fiber bundle, the fiber bundle is preferably conveyed substantially straight (Aspect 2). According to the Aspect 2, it is possible to obtain excellent high speed productivity of a cleaning member and to efficiently produce a cleaning member. Here, the “fiber bundle being conveyed substantially straight” means the fiber bundle being conveyed without snaking. - In the
Aspect - In any of the aspects of the
Aspects 1 to 3, in the step of conveying the fiber bundle, the fiber bundle is preferably conveyed with the length of the fiber bundle in the width direction substantially constant (Aspect 4).

The “length of belt-shaped nonwoven fabric in the width direction substantially constant” means the length of the fiber bundle in the width direction does not become shorter than the width due to tension of the fiber bundle. According to the Aspect 5, it is possible to obtain excellent high speed productivity of a cleaning member and to efficiently produce a cleaning member. - In the aspect of the Aspect 5, the step of fastening the multilayer web is preferably a step of melt bonding (Aspect 6). In another aspect, the step of fastening is a step of fastening by a hot melt adhesive.
- In any of the aspects of the
Aspects 1 to 6, the fiber bundle is preferably an opened fiber bundle (Aspect 7). To open the fiber bundle, the method of producing a cleaning member according to the present invention includes a step of opening the fiber bundle. - In any of the aspects of the
Aspects 1 to 7, the method further includes a step of cutting the multilayer web in the width direction (Aspect 8). - In the method of producing a cleaning member according to the present invention, two or more of the
Aspects 1 to 8 may be combined. - [System of Producing Cleaning Member]

- The system of producing a cleaning member according to the present invention is a novel system of production which is suitable for producing a cleaning member which is excellent in cleaning performance and which further enables efficient production. Due to the fact that a tension of the fiber bundle at the device which conveys the fiber bundle is lower than a tension of the belt-shaped nonwoven fabric at the device which conveys the belt-shaped nonwoven fabric, the piles of the fiber bundle which form the cleaning member will never become shorter than the width of the belt-shaped nonwoven fabric, so the fiber bundle can more easily contact dust, dirt, etc. and the cleaning performance is improved and, further, the fiber bundle and belt-shaped nonwoven fabric, in particular the fiber bundle, become hard to cut at the time of conveyance, in particular, become hard to be cut by melting at the time of melt bonding or other fastening of the later explained fiber bundle and belt-shaped nonwoven fabric, so the high speed productivity becomes excellent. Further, by adjusting the tension of the fiber bundle and the tension of the belt-shaped nonwoven fabric, the strength of sealing of the multilayer web can be controlled and kept from dropping.

The holdingsheet 13 is overlaid on the top side of thesubstrate sheet 12 so that two end parts of thesubstrate sheet 12 in the long direction stick out outward from the two ends of the holdingsheet 13 in the long direction by predetermined lengths. - The
substrate sheet 12 and holdingsheet 13 are formed from nonwoven fabrics which are comprised of thermoplastic fibers (hot bondable fibers) or nonwoven fabrics which include thermoplastic fibers. As thermoplastic fibers, for example, polyethylene fibers, polypropylene fibers, polyethylene terephthalate fibers, polyethylene and polyethylene terephthalate composite fibers, polyethylene and polypropylene composite fibers, core-sheath type composite fibers comprised, for example, of a core comprised of polyethylene terephthalate and a sheath comprised of polyethylene, etc. may be mentioned. As types of nonwoven fabrics, for example, thermal bond nonwoven fabrics, spunbonded nonwoven fabrics, spunlace nonwoven fabrics, etc. may be mentioned. - As other embodiments, embodiments in which the substrate sheet and the holding sheet are formed from thermoplastic resin films, for example, polyethylene films and polypropylene films, may be mentioned, while as further embodiments, embodiments in which the substrate sheet and the holding sheet are formed from laminate sheets of nonwoven fabrics and resin films may be mentioned.
- The
substrate sheet 12 and the holdingsheet 13 are integrally melt bonded by a later explained first melt bondedpart forming device 158 together with all of the layers of the brush sheet 2 (first fibrous member 3, secondfibrous member 4, third fibrous member 5, fourth fibrous member 6, and sheet with slits 7), whereby the cleaningmember 1, as shown inFIG. 1 toFIG. 3 , is formed with a first melt bondedpart 8 extending in the long direction at the center part in the width direction. Furthermore, thesubstrate sheet 12 and the holdingsheet 13 are integrally melt bonded at the two sides of the first melt bonded part 8 (left and right inFIG. 2 ) by a later explained second melt bondedpart forming device 134 together with one layer of the brush sheet 2 (first fibrous member 3), whereby the cleaningmember 1 is formed with two second melt bondedparts 11 in the long direction. The two second melt bondedparts 11 are respectively formed intermittently. By the first fibrous member 3 being melt bonded with thesubstrate sheet 12 and the holdingsheet 13, the first fibrous member 3 tracks movement of thesesheets brush sheet 2 easily becomes broader and, and in turn, the cleaning efficiency is improved. - The
substrate sheet 12 and the holdingsheet 13 are melt bonded at the first melt bondedpart 8 with all layers of the brush sheet 2 (first fibrous member 3, secondfibrous member 4, third fibrous member 5, fourth fibrous member 6, and sheet with slits 7) and is melt bonded with the first fibrous member 3 of thebrush sheet 2 at the two second melt bondedparts 11.

The cleaningmember 1, as shown inFIG. 3 , is formed with a pair ofmelt bonding lines 18 at a predetermined interval in the width direction of thesubstrate sheet 12 and the holdingsheet 13. Between the pair ofmelt bonding lines 18, the first melt bondedpart 8 is formed. The pair ofmelt bonding lines 18 are marks for management of the position of the first melt bondedpart 8 at the stage of production. By managing whether the first melt bondedpart 8 is arranged between the pair ofmelt bonding lines 18 by sensors etc., it is possible to separate good products and bad products. - As shown in
FIG. 1 toFIG. 3 , the two second melt bondedparts 11 are provided intermittently at several locations in the long directions of thesubstrate sheet 12 and the holdingsheet 13. By engaging the arc shapedprojections 16 a of theinsert parts 16 of thehandle 16 with nonmelt bonded parts of the two second melt bondedparts 11, theinsert parts 16 of thehandle 15 can be prevented from being pulled out from the receivingparts 14. - As shown in
FIG. 1 , the two edge parts of thesubstrate sheet 12 and the holdingsheet 13 in the width direction (outside parts of two second melt bonded part 11) are provided with sawtooth shapedslits 20 a at predetermined intervals along the long direction. Due to theslits 20 a, the two edges are provided with sawtooth shaped reed-shapedparts 20. As another embodiment, an embodiment in which thesubstrate sheet 12 and the holdingsheet 13 are not provided with sawtooth shapedslits 20 a and therefore the reed-shapedparts 20 are not provided may be mentioned. - As shown in
FIG. 1 , thehandle 15 has a pair of long plate shapedinsert parts 16 which are arranged in parallel to each other, a pair of arc-shapedprojections 16 a which stick out from the outside surfaces of the two ends parts in the long directions of theinsert parts 16, and aholder 17 which is provided integrally with one of the end parts of theinsert parts 16 and is, for example, formed from a plastic etc. - By inserting the two
insert parts 16 of thehandle 15 inside the two receivingparts 14 of the cleaningmember 1 and engaging theprojections 16 a with non-melt bonded parts of the two second melt bondedparts 11, the cleaningmember 1 is attached to thehandle 15.

The method and the system of producing a cleaning member according to the present invention can be used to produce a cleaning member as described in, for example, U.S. Pat. No. 6,554,937B, US2002/148061A, US2003/0000934A, US2004/0149095A, US2005/0005381A, US2005/039285A, US2005/097695A, US2005/097696A, US2005/132521A, US2005/177967A, US2005/188490A, US2005/193513A, US2005/193514A, US2005/198760A, US2006/016035A, US2006/016036A, US2006/101601A, US2009/165230A and US2009/172904A, as well as US2009/049633A, US2009/255078A and US2010/154156A, the entire disclosures of which are incorporated herein by reference. - Next, one embodiment of the method and system for producing the cleaning
member 1 will be explained based onFIG. 4 . -
FIG. 4 is a schematic view for explaining the method and system for producing the cleaningmember 1. In the present embodiment, thesystem 100 which is shown inFIG. 4 is used to work the method for producing the cleaningmember 1 and produce the cleaningmember 1. - In the present embodiment, the method of production of the cleaning
member 1 includes thefollowing Step 1 andStep 2. - [Step 1] Step of opening fiber bundles to step of conveying them
- [Step 2] Step of using fiber bundles to produce multilayer web and cutting out cleaning
member 1 from multilayer web - <
Step 1> - Below,
Step 1 will be explained. - In the present embodiment,
Step 1 includes the following Step 1 a and Step 1 b. - [Step 1 a] Step of opening first fiber bundle F1 to fourth fiber bundle F4
- [Step 1 b] Step of conveying first fiber bundle F1 to fourth fiber bundle F4
- In the present embodiment,
Step 1 includes Step 1 a, but the presence or absence of Step 1 a may be suitably selected in accordance with the type of the fiber bundles used. As another embodiment, an embodiment in which Step 1 a is omitted may be mentioned. For example, when the fiber bundles are comprised of noncrimped fibers, Step 1 a may be omitted. - [Step 1 a]
- Below, Step 1 a will be explained with reference to the example of the step of opening the first fiber bundle F1, but the steps of opening the other fiber bundles are similarly performed.
- The first fiber bundle F1 which is comprised of crimped fibers is continuously pulled out from a storage container (not shown) and sent to first nip rolls 102 a and 102 b which rotate by a certain peripheral velocity V1. After passing the first nip rolls 102 a and 102 b, the first fiber bundle F1 passes through a plurality of tension rolls 104 and is sent to second nip rolls 106 a and 106 b which rotate by a peripheral velocity V2.
- The peripheral velocity V2 of the second nip rolls 106 a and 106 b is faster than the peripheral velocity V1 of the first nip rolls 102 a and 102 b. Due to this difference in peripheral velocities, between the first nip rolls 102 a and 102 b and the second nip rolls 106 a and 106 b, the first fiber bundle F1 is given tension. As a result, the first fiber bundle F1 is opened.
- The tension rolls 104, for example, are formed from solid steel and are adjusted in mass so that a considerable degree of force is required to rotate them. Therefore, while the first fiber bundle F1 is turning the tension rolls 104 and advancing from the first nip rolls 102 a and 102 b toward the second nip rolls 106 a and 106 b, the speed of movement of the first fiber bundle F1 does not rapidly increase.
- The tension rolls 104 are arranged to be able to gradually open the first fiber bundle F1 by the distance between the first nip rolls 102 a and 102 b and the second nip rolls 106 a and 106 b becoming longer.
- The first fiber bundle F1 which passes through the second nip rolls 106 a and 106 b passes through an
air feeder 108 and is sent to third nip rolls 112 a and 112 b which rotate by a peripheral velocity V3. The peripheral velocity V3 of the third nip rolls 112 a and 112 b is slower than the peripheral velocity V2 of the second nip rolls 106 a and 106 b. Due to this difference in peripheral velocities, between the second nip rolls 106 a and 106 b and the third nip rolls 112 a and 112 b, the tension of the first fiber bundle F1 is eased. As a result, the first fiber bundle F1 is further opened and the width of the first fiber bundle F1 is expanded. - The first fiber bundle F1 which is sent to the second nip rolls 106 a and 106 b to the third nip rolls 112 a and 112 b is blown with air from the
air feeder 108. As a result, the first fiber bundle F1 is further opened. - In the present embodiment, to open the first fiber bundle F1, the operation of imparting and easing tension and the operation of blowing air are used, but the opening method may be suitably changed. As another embodiment, an embodiment in which either the operation of imparting and easing tension and the operation of blowing air is used may be mentioned. Further, as another embodiment, an embodiment in which the operation of imparting and easing tension and the operation of blowing air plus use of another opening method may be mentioned. Further, in the present embodiment, for the operation of imparting and easing tension, first to third nip rolls are used, but the number of nip rolls can be suitably changed. As another embodiment, for the operation of imparting and easing tension, an embodiment in which other nip rolls are used in addition to the first to third nip rolls may be mentioned.
- The
oil tank 114 contains an oil. In the present embodiment, the oil which is contained in theoil tank 114 is a dust catching oil which has the action of promoting adsorption of dust, dirt, etc. (for example, oil mainly comprised of liquid paraffin). - [Step 1 b]
- Below, in Step 1 b, the conveyance step for the first fiber bundle F1 will be explained as an example, but the conveyance step for other fiber bundles are similarly performed.
- If passing the third nip rolls 112 a and 112 b, the first fiber bundle F1 does not pass the nip rolls, tension rolls, etc. until the merging
part 132, so the first fiber bundle F1 is not given a stronger tension from the first nip rolls 102 a and 102 b than the tension between the third nip rolls 112 a and 112 b. - Further, the first fiber bundle F1 advances to the merging
part 132. Similarly, after Step 1 b, the second to fourth fiber bundles F2 to F4 respectively advance to the mergingparts - <
Step 2> - Below,
Step 2 will be explained. - In the present embodiment,
Step 2 includes the following Step 2 a to Step 2 c. - [Step 2 a] Step of laying fiber bundle after Step 1 b over other member (in the present embodiment, belt-shaped nonwoven fabric) to form multilayer web
- [Step 2 b] Step of fastening fiber contained in multilayer web with other members
- [Step 2 c] Step of cutting out
individual cleaning members 1 from multilayer web - [Step 2 a]
- Below, Step 2 a will be explained.
- In the present embodiment, the other member which is overlaid with fiber bundles after Step 1 b is a belt-shaped
nonwoven fabric - The belt-shaped
nonwoven fabrics substrate sheet 12 and holdingsheet 13 of the cleaningmember 1. The belt-shapednonwoven fabric 121 is continuously unrolled from anonwoven fabric roll 120 and is intermittently conveyed by being passed through dancer rolls 124 which include a plurality of rolls arranged in two top/bottom stages and where the rolls which are positioned at the bottom stage rock up and down. Similarly, the belt-shapednonwoven fabric 123 is continuously unrolled from anonwoven fabric roll 122 and is intermittently conveyed by being passed through dancer rolls 126 which include a plurality of rolls arranged in two top/bottom stages and where the rolls which are positioned at the bottom stage rock up and down. Note that, “intermittently conveyed” means the belt-shapednonwoven fabrics nonwoven fabrics - The belt-shaped
nonwoven fabrics part 128. The multilayer web S1 passes through gathercutters 130 at the surfaces of which sawtooth shaped blades (not shown) at intermittently formed at their surfaces in the peripheral direction. Due to this, slits are formed which correspond to theslits 20 a of thesubstrate sheet 12 and holding sheet 13 (seeFIG. 1 ). Further, the multilayer web S1 advances to a mergingpart 132 while maintaining a certain tension. - The multilayer web S1 merges at the merging
part 132 with the first fiber bundle F1 which has passed throughStep 1 and which has not been given tension. The first fiber bundle F1 is overlaid on the multilayer web S1 whereby the multilayer web S2 is formed. The first fiber bundle F1 is configured to slack a certain extent between the third nip rolls 112 a and 112 b and mergingpart 132. Due to this, the dancer rolls act in the same way as if provided between them. That is, the first fiber bundle F1 becomes a state not given tension between the third nip rolls 112 a and 112 b and the mergingpart 132. - The multilayer web S2 successively merges at the merging
parts Step 1 whereby the second fiber bundle F2 to fourth fiber bundle F4 are successively overlaid on the multilayer web S2 and the multilayer web S3 is formed. - The belt-shaped
nonwoven fabric 151 corresponds to a sheet with slits 7 of the cleaningmember 1. The belt-shapednonwoven fabric 151 is continuously unrolled from anonwoven fabric roll 150 and passed through dancer rolls 152 to thereby be intermittently conveyed and, further, passes through gather rolls 154. The gather rolls 154 have continuous sawtooth shaped blades (not shown) at their surfaces in their peripheral directions. Due to this, sawtooth shaped slits (not shown) are formed in the belt-shapednonwoven fabric 151 which passes through the gather rolls 154. - The belt-shaped
nonwoven fabric 151 merges at the mergingpart 156 with the multilayer web S3 whereby the belt-shapednonwoven fabric 151 is laid over the multilayer web S3 and the multilayer web S4 is formed. - [Step 2 b]
- Below, Step 2 b will be explained.
- The multilayer web S2 passes through the second melt bonded
part forming device 134 before the second fiber bundle F2 to fourth fiber bundle F4 merge. The second melt bondedpart forming device 134 melt bonds the belt-shapednonwoven fabric FIG. 3 ). Due to this, the multilayer web S2 is melt bonded across its thickness direction. In the present embodiment, as the second melt bondedpart forming device 134, a heat seal device is used, but another sealing device (for example, ultrasonic wave sealing device etc.) may also be used. - The multilayer web S4 passes through the first melt bonded
part forming device 158. The first melt bondedpart forming device 158 melt bonds the multilayer web S4 as a whole and forms a first melt bondedpart 8 at the multilayer web S4 (seeFIG. 3 etc.) Due to this, the multilayer web S4 is melt bonded over the thickness direction. In the present embodiment, as the first melt bondedpart forming device 154, a heat seal device is used, but the melt bonded part forming device may be suitably changed. As another embodiment, an embodiment in which an ultrasonic wave sealing device is used may be mentioned. - [Step 2 c]
- Below, Step 2 c will be explained.
- The multilayer web S4 which passes through the first melt bonded
part forming device 158 is cut by thecutting device 160 wherebyindividual cleaning members 1 are cut out. - The cleaning
member 1 which is produced by the present embodiment includes a sheet with slits 7, but a cleaning member which is produced by another embodiment does not contain the sheet with slits 7. Further, in the cleaningmember 1 which is produced by the present embodiment, the receivingparts 14 are positioned on the surface of the cleaningmember 1, but in a cleaning member which is produced by another embodiment, the order of lamination of thesubstrate sheet 12 and the holdingsheet 13 and the fibrous members 3 to 6 is changed so that the receivingparts 14 are arranged between any adjoining fibrous members 3 to 6. Due to this, the two surfaces of the cleaningmember 1 can be used for cleaning. At this time, to facilitate insertion of theinsert parts 16 to the receivingparts 14, the dimensions of thesubstrate sheet 12 and the holdingsheet 13 in the long direction (up-down direction inFIG. 3 ) are preferably made longer than the fibrous members 3 to 6, but these dimensions may be freely determined. Further, at this time, the sheet with slits 7 need not be used. Sheet with slits 7 may also be arranged at the two surfaces of the cleaningmember 1. -
