Description

  The present invention relates to a composite nonwoven fabric wiper obtained by hydroentanglement treatment of a combination web formed by combining pulp fibers and other fibers and a spunbond web obtained by a spunbond method, and a method for producing the same. .

  A composite nonwoven fabric wiper in which a pulp fiber web and a spunbond web are integrated is obtained by laminating a natural fiber web made of pulp and a spunbond web and then hydroentangling them. Since such a nonwoven fabric wiper becomes an excellent nonwoven fabric product having both strength and water absorption, it is used in various applications as a wiper for wiping off dirt.

  The composite type non-woven wiper as described above using pulp fibers is excellent in wiping as an industrial wiper, but there is still room for improvement in terms of texture and bulkiness when used as a personal wiper. There is.

  Therefore, an object of the present invention is to provide a nonwoven fabric wiper that is not only wiping but also excellent in texture and bulkiness and has higher versatility.

  The above object is a nonwoven fabric wiper formed by integrally laminating a combination web containing pulp fibers, regenerated fibers and composite synthetic fibers and a spunbond web obtained by a spunbond method, The content ratio of each fiber can be achieved by a non-woven wiper characterized in that the pulp fiber is 50 to 85% by weight, the regenerated fiber is 10 to 30% by weight, and the composite synthetic fiber is 5 to 20% by weight. .

The combination web can be formed as a mixed web in which the pulp fiber, regenerated fiber and composite synthetic fiber are uniformly mixed and integrated.
In this case, the regenerated fiber is preferably at least one fiber selected from the group consisting of rayon, cupra, lyocell, and polynosic, and the fiber length is preferably 20 mm or less.
The composite synthetic fiber is formed using at least two types of synthetic resins having different melting temperatures, and the fiber length is preferably 20 mm or less.

On the other hand, the combined web is formed as a laminated web in which a pulp fiber layer made of the pulp fibers and a combined fiber layer made of the regenerated fibers and the composite synthetic fibers are laminated, and the pulp fiber layer of the laminated web is You may employ | adopt the structure which is the spun bond web side.
In this case, the regenerated fiber is at least one fiber selected from the group consisting of rayon, cupra, lyocell and polynosic, and preferably has a fiber length of 21 mm to 61 mm.
The composite synthetic fiber is formed using at least two kinds of synthetic resins having different melting temperatures, and the fiber length is preferably 21 mm to 61 mm.

The weight ratio of the spunbond web to the combination web is preferably 2: 8 to 5: 5, and the basis weight of the nonwoven fabric wiper is preferably ²⁰ to 90 g / m ² .

  And the above-mentioned object is a method for producing a nonwoven fabric wiper in which a combination web including pulp fiber, regenerated fiber and composite synthetic fiber and a spunbond web obtained by a spunbond method are laminated and formed integrally, A combined web forming step of forming a mixed web in which the pulp fiber, regenerated fiber and composite synthetic fiber are uniformly mixed and integrated as the combined web using an airlaid device, and a spunbond obtained by a spunbond method A laminating step of laminating the combination web on a web, and a entanglement treatment step of performing hydroentanglement treatment on the laminated combination web and the spunbond web to obtain an integrated nonwoven fabric wiper. It can achieve by the manufacturing method of the nonwoven fabric wiper which makes it.

  Furthermore, the above object is a method for producing a nonwoven fabric wiper, in which a combination web containing pulp fibers, regenerated fibers and composite synthetic fibers and a spunbond web obtained by a spunbond method are laminated and formed integrally. As the combination web, a combination web is formed to form a laminated web in which a combination fiber layer made of the recycled fiber and the composite synthetic fiber formed by using a card device is laminated on a pulp fiber layer made of the pulp fiber. A laminated step of laminating the combined web on a spunbonded web obtained by a spunbond method, hydroentangled the laminated web and the spunbonded web, and forming an integrated non-woven wiper It can also be achieved by a method for manufacturing a non-woven wiper characterized in that it includes an entanglement treatment step.

The nonwoven fabric wiper of the present invention is excellent not only in wiping properties but also in texture and bulkiness, and can be provided as a more versatile nonwoven fabric wiper.
Moreover, according to the manufacturing method of this invention, the said nonwoven fabric wiper can be manufactured.

It is the figure shown about the manufacturing apparatus which enforces the manufacturing method of an example suitable for the nonwoven fabric wiper which concerns on this invention.

  Hereinafter, an embodiment of the present invention will be described. The nonwoven fabric wiper according to the present invention has a composite structure in which a combination web composed of pulp fibers, recycled fibers and composite synthetic fibers and a spunbond web obtained by a spunbond method are laminated and integrally formed. It is what you have.

Pulp fibers are excellent in wiping property because they are rich in water absorption (liquid absorption). However, since the pulp fiber has a structure in which cellulose is hydrogen-bonded, it is easy to form a web that is hard and has a poor texture. The fibers added to make up for this deficiency are the recycled fiber and the composite synthetic fiber.
And the regenerated fiber has a fiber length equal to that of the pulp fiber and contributes to the strength stabilization of the non-woven wiper because the ratio of the long fiber is high. Moreover, since it is hydrophilic, it also contributes to the improvement of water absorption. On the other hand, since it is more expensive than pulp fiber, it is desirable to suppress the blending amount from the viewpoint of cost.
Moreover, since the composite synthetic fiber does not form hydrogen bonds with the pulp fiber, it contributes to improvement in bulkiness and texture. However, if the composite synthetic fiber is too much, there is a concern that the hydrophilicity of the nonwoven fabric wiper is lowered.

Considering the above points comprehensively, the combination web of the nonwoven fabric wiper of the present invention has a ratio of 50 to 85% by weight of pulp fibers, 10 to 30% by weight of recycled fibers, and 5 to 20% by weight of composite synthetic fibers. ing.
The weight ratio between the spunbond web and the combination web is preferably 2: 8 to 5: 5. The basis weight of the nonwoven fabric wiper is preferably 20~90g / ^{m 2,} more preferably from 30~90g / ^{m 2.}
By specifying as described above, since the fibers exhibit their respective functions, it is possible to produce a nonwoven fabric wiper that is excellent in wiping properties and improved in texture and bulkiness. And also from the viewpoint of cost, a nonwoven fabric wiper can be manufactured efficiently.

As the pulp fiber, radiate pine, slash pine, southern pine, lodgepole pine, spruce and douglas fir selected softwood bleached kraft pulp can be employed.
The regenerated fiber is preferably selected from the group consisting of rayon, cupra, lyocell and polynosic. A plurality of regenerated fibers may be used in combination.

Furthermore, the composite synthetic fiber is preferably formed using at least two types of synthetic resins having different melting temperatures. Such a composite synthetic fiber can be, for example, a composite heat-fusible fiber designed in a known core-sheath structure. Here, as the first synthetic resin having a relatively high melting point constituting the core portion, for example, polyesters such as polyethylene terephthalate and polybutylene terephthalate, polyamides such as nylon 6, nylon 6, 6, etc., polymethylpentene, polypropylene Polyolefin homopolymers such as ethylene-propylene copolymer and ethylene vinyl alcohol copolymer, copolymers, graft modified products, and thermoplastic resins such as polymer alloys thereof can be used.
And as a 2nd synthetic resin which has relatively low melting point which comprises a sheath part, propylene copolymers, such as polyethylene, an ethylene-propylene copolymer, an ethylene-butene-1-propylene terpolymer, ethylene, for example -Thermoplastic resins such as vinyl acetate copolymer and ethylene-methyl acrylate copolymer can be used.
The composite synthetic fiber is not limited to the core-sheath structure, but may be a so-called side-by-side structure.

  The spunbond web is a web made of a synthetic resin such as polypropylene (PP) or polyethylene terephthalate (PET) by a known spunbond method. The spunbond web has predetermined rigidity and strength, and fulfills the function of maintaining the shape of the nonwoven fabric wiper.

By the way, the “combination web” included in the nonwoven fabric wiper of the present invention can be in the form of a “mixed web” in which the pulp fiber, regenerated fiber and composite synthetic fiber are uniformly mixed and integrated.
The “combination web” may be in the form of a “laminated web” in which a pulp fiber layer composed of the pulp fibers and a combination fiber layer composed of the regenerated fibers and composite synthetic fibers are laminated on the pulp fiber layer. . The laminated web will be described in detail later.

In the following, an exemplary embodiment in which the combination web is configured as a mixed web will be described first.
In the mixed web, the above three kinds of fibers, pulp fibers, regenerated fibers and composite synthetic fibers are uniformly mixed and integrated. Such a mixed web can be preferably manufactured using an air laid apparatus as described later.

  The regenerated fiber used here is, for example, rayon, and the fiber length is preferably a short fiber of 20 mm or less. The fiber length of the regenerated fiber is preferably 20 mm or less from the viewpoint of efficiently mixing fibers using an airlaid device and further realizing reliable entanglement between the fibers when subjected to hydroentanglement processing downstream thereof. . The fiber length is more preferably 5 mm or less.

  The composite synthetic fiber may be a core-sheath fiber made of, for example, polyethylene (PE) and polypropylene (PP). The composite synthetic fiber used in the mixed web is also preferably 20 mm or less in fiber length. If the fiber length of the composite synthetic fiber exceeds 20 mm, uniform mixing may be hindered when mixed using an airlaid device.

  Hereinafter, a method for producing a nonwoven fabric wiper of the present invention having a mixed web (combination web) on a spunbond web will be described using a suitable production apparatus illustrated in FIG.

In the nonwoven fabric wiper manufacturing apparatus 1 shown in FIG. 1, an airlaid device 2, a spunbond web supply device 3, and a suction device 4 are arranged on the upstream side. The suction device 4 is arranged to face the lower side of the air laid device 2.
In the transport direction TD, downstream from these devices 2, 3, 4, a water jet device 5 and a drying device 6 are arranged in order from the upstream side. A winding device 7 for winding the continuously produced non-woven wiper CWeb is further provided downstream of the drying device 6.

The air laid apparatus 2 supplies the fiber pulp PF that has been defibrated with a defibrator 21 that defibrates the raw pulp RP, in which the fibers are densely packed into a sheet shape, into pulp fibers, and a blower (not shown). And a duct 22 for conveying.
In the middle of the duct 22, a recycled fiber input duct 25 for supplying the regenerated fiber RF in a defibrated state and a composite in a defibrated state so as to merge with the flow of the defibrated pulp fiber PF. A composite synthetic fiber charging duct 26 for charging the synthetic fiber CSF is additionally provided.
Here, the blending ratio (% by weight) of the pulp fiber PF, the recycled fiber RF, and the composite synthetic fiber CSF can be arbitrarily adjusted by a sensor or a measuring instrument (not shown).

An air-laid hopper 23 is disposed downstream of the duct 22. Inside the air laid hopper 23, the above three kinds of fibers in a defibrated state are lowered while being dispersed, and are gradually piled up at a stacking position 24 set on the lower surface. As a result, a mixed web MW in which the pulp fiber PF, the recycled fiber RF, and the composite synthetic fiber CSF are uniformly mixed is formed (combined web forming step).
A suction device 4 is disposed opposite to the lower side of the stacking position 24. More specifically, the suction device 4 has a suction portion 42 on the upper surface of the device body 41, and the suction portion 42 is set with respect to the stacking position 24 so as to apply a suction force (negative pressure) to the mixed web MW. It is.

Further, a transport wire 43 for transporting the web is disposed around the suction device 4. The conveying wire 43 can be placed with the mixed web MW at the stacking position 24, and is arranged so as to convey it downstream. However, the mixed web MW is not placed directly on the transport wire 43. This will become clear from the following description.
The carrier wire 43 is formed in an open-mesh shape (mesh) so that the suction force of the suction part 42 extends to the opposite side (upper side).

  A spunbond web supply device 3 is disposed below the air laid device 2 and upstream of the suction device 4. In this spunbond web supply device 3, a spunbond web SW prepared in advance is set in a roll shape. The spunbond web SW is pulled out from the spunbond web supply device 3 and is transported to the stacking position 24 on the transport wire 43 described above. As the spunbond web SW, a continuous filament web of synthetic resin formed by a spunbond method is preferably used.

  The above-mentioned mixed web MW is placed on the spunbond web SW located at the laminating position 24 (lamination process). At that time, at the stacking position 24, the suction force by the suction part 42 of the suction device 4 passes through the transport wire 43 and acts on the spunbond web SW and the mixed web MW. Therefore, the preliminary laminated body PWeb in which the spunbond web SW and the mixed web MW are laminated is conveyed to the downstream side.

The above-described preliminary laminated body PWeb is maintained in a laminated state by being sucked and compressed by the suction force of the suction device 4. At this time, the upper mixed web MW is in a state where three kinds of fibers are densely packed. However, if the preliminary laminate PWeb is conveyed and introduced into the downstream water jetting device 5 as it is, a part of the pulp fiber PF may be swollen by the water flow (water jet).
Therefore, in the present manufacturing apparatus 1, the preliminary laminated body PWeb is sandwiched from above and below, the sandwiching roller 28 for stabilizing the mounting state of the mixed web MW on the spunbond web SW, and the upstream side of the water jetting apparatus 5. Further, a prewetting device 30 for providing moisture to the pulp fiber PF to prevent scattering is provided. The prewetting apparatus 30 preferably applies a suction force from the spray nozzle 31 that sprays water mist from above the preliminary laminate PWeb and the lower side of the preliminary laminate PWeb (that is, the lower surface of the spunbond web SW). And a suction device 32.

The water jet device 5 promotes the confounding of the pulp fibers by blowing a high-pressure water jet to the preliminary laminate PWeb that has been subjected to the processing of the pretreatment units 28 and 30. Thereby, integration of the mixed web MW layer located on the upper side and the spunbond web SW layer located on the lower side is promoted (entanglement process step).
In the water jet device 5 shown as an example in FIG. 1, water jet nozzles 51 are arranged in multiple stages (four stages are illustrated in FIG. 1) along the transport direction TD. It is good also as a substitute for the pre-wet apparatus 30 mentioned above by spraying the 1st stage water-flow injection nozzle by low pressure.
In FIG. 1, the state of the nozzles in the direction perpendicular to the transport direction TD (the width direction of the apparatus 1) is not shown, but a plurality of water jet nozzles are also arranged in the width direction.

  It is desirable that the water pressure at the time of the hydroentanglement treatment is set in consideration of the basis weight of the mixed web MW and the spunbond web SW. For example, it is preferable to select in the range of 1 to 30 MPa.

  A suction device 52 is disposed so as to face the water jet nozzle 51. The suction force of the suction device 52 is applied to the lower side of the spunbond web SW located on the lower side while blowing the high-pressure water jet coming out of the water jet nozzle 51 to the pulp web located on the upper side. Due to the cooperative action of the water jet nozzle 51 and the suction device 52, the mixed web MW side fibers have entered the lower spunbond web SW or have passed through the spunbond web SW to the opposite side. Etc. are estimated to be formed. The action promotes the integration of the two layers.

The water jet device 5 is also provided with a transport wire 55. The transport wire 55 receives the preliminary laminate PWeb downstream of the pretreatment units 28 and 30 and transports it into the water jetting device 5. The transport wire 55 is disposed so as to pass between the water jet nozzle 51 and the suction device 52 of the water jet device 5 from the upstream side toward the downstream side.
Therefore, the preliminary laminated body PWeb transported on the transport wire 55 is subjected to more hydroentanglement processing as it goes downstream in the transport direction TD. Sufficient confounding processing between the MW layer and the lower spunbond web SW layer is realized.
Immediately after leaving the water jetting device 5, the web is in a wet state, and before drying, the bonding between the pulp fibers and the like is not sufficiently established.

Therefore, as shown in FIG. 1, a drying device 6 is provided on the downstream side of the water jetting device 5 to dry the laminate and complete the manufacture of the nonwoven fabric wiper. The drying device 6 employed here is an uncompressed dryer, and preferably an air-through dryer.
In FIG. 1, the rotatable dryer body 61 of the air-through dryer is a cylindrical body, and a large number of through holes are provided on the peripheral surface thereof, and hot air heated by a heat source (not shown) is centered from the outer periphery of the dryer body 71. It is the structure which inhales toward the part side.
In addition, when the web of the nonwoven fabric wiper is heated as described above, it acts so that at least a part of the above-mentioned composite synthetic fiber having a low melting point is thermally fused. It will contribute to improvement.
The composite nonwoven fabric wiper CWeb thus continuously manufactured is wound around the roller 71 of the winding device 7 to complete a series of steps.

  The non-woven wiper manufactured as described above has a combination web that can improve inconveniences when a web made only of pulp fibers is used on a spunbond web, so that it has a wiping property, and further has a texture and bulkiness. As a result, the nonwoven fabric wiper is improved for human use.

(Example)
Hereinafter, the Example of the nonwoven fabric wiper of this invention provided with the mixing web manufactured as mentioned above is described.
The fibers used in the mixed web are as follows.
Pulp fiber Grade: Southern pine Fiber length: 2.5mm
Recycled fiber Composition: Rayon Fiber length: 5mm
Composite synthetic fiber Composition: Polyethylene (PE) / Polypropylene (PP)
Fiber thickness: 2.2dtex Fiber length: 5mm

Using the manufacturing apparatus shown in FIG. 1, the nonwoven fabric wipers of Examples and Comparative Examples shown in Table 1 below are manufactured as described above, and the thickness (mm), texture (sensory evaluation), strength based on a tensile test, A comprehensive judgment was made for water absorption.
Evaluation was performed under the following conditions.
The measuring method of the nonwoven fabric wiper is as follows.
Thickness: Measured with a Peacock paper thickness gauge under a load of 37.85 g / cm ² .
・ Feel: Monitor survey by 8 people.
The evaluation was made on a four-point scale [◎ particularly good, ○ good, Δ: equivalent, × poor].
Strength: Measured as tensile strength during drying based on JISP8113.
-Water absorption: Based on the water absorption rate test stipulated in JIS S 3104, the time from when the amount of dropped water was changed to 0.5 mL and when the water droplets reached the surface of the test piece until the specular reflection of the test piece disappeared (Seconds) was measured and evaluated. Here, it is assumed that sufficient water absorption is provided when the time is 2 seconds or less, and x when the time exceeds 2 seconds.
The top row of Table 1 below shows the composition of the mixed web by weight (%). The basis weight of the mixed web can be obtained by subtracting the basis weight of the spunbond from the basis weight of the nonwoven fabric wiper (whole).

Although the nonwoven fabric wiper demonstrated above demonstrated the case where the mixed web manufactured with an airlaid apparatus was employ | adopted as a combination web, it is not restricted to this. A laminated web manufactured using a card device may be adopted as the combination web.
The laminated web described above is configured as a laminated form of a pulp fiber layer made of pulp fibers and a combined fiber layer made of recycled fibers and composite synthetic fibers produced using a card device.
The above-mentioned combination fiber layer may be a mixed fiber layer obtained by card processing by mixing recycled fibers and composite synthetic fibers, or a single-layer web form, or the recycled fibers and composite synthetic fibers may be individually carded. It is good also as a 2 layer web form by processing and a regenerated fiber layer and a composite synthetic fiber layer.
The pulp fiber layer may employ a pulp fiber sheet (web) prepared in advance or a web formed by an air laid apparatus as described above.
The laminated web is preferably laminated on the spunbond web with the pulp fiber layer on the lower side.

Specifically, as the card device, a known card machine (a device that unwinds fiber cotton and aligns the fiber direction) conventionally used in the spinning process is used to combine the recycled fiber and the composite synthetic fiber. By blending, it is possible to obtain a web in which the former mixed fiber layer is one layer.
When the latter combination fiber layer is composed of two layers, two card devices are prepared and the recycled fiber layer web and the composite synthetic fiber layer web are individually formed.
A non-woven wiper having a laminated web as a combination web can be manufactured by additionally arranging the card device as described above on the downstream side of the air laid device of FIG.
In the case of the latter laminated web, since it becomes 3 layers including a pulp fiber layer, a manufacturing facility becomes complicated. Therefore, it is preferable to employ the laminated web in the former form.

  In the above laminated web, it is preferable to adopt a fiber having a relatively long fiber length as compared with the case of the mixed web described above. For regenerated fiber and composite synthetic fiber, the fiber length is 21 mm to 61 mm. preferable. Thus, since the fiber length of the recycled fiber and composite synthetic fiber contained in the laminated web is longer than that of the mixed web described above, the strength is improved. Therefore, the nonwoven fabric wiper employing the laminated web can be provided as a relatively strong wiper.

In the nonwoven fabric wiper according to the present invention described above, the combination web arranged on the spunbond web includes regenerated fibers such as rayon fibers and composite synthetic fibers in addition to pulp fibers. Recycled fibers are hydrophilic and have a fiber length longer than that of pulp fibers, so that the fiber lengths are uniform, so that the function of the nonwoven fabric wiper is improved in terms of both hydrophilicity improvement and reinforcement. And since a composite synthetic fiber does not form a hydrogen bond with a cellulose fiber, it contributes to the improvement of bulkiness and a texture.
Therefore, in the nonwoven fabric wiper which concerns on this invention, it is excellent not only in wiping property but a feeling and bulkiness, and becomes a more versatile nonwoven fabric wiper.
And the said combination web contained in the nonwoven fabric wiper of this invention can be manufactured using an airlaid apparatus and a card apparatus.

  Although the description of the embodiment has been completed above, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the scope of the invention.
