Description
本発明は、不織布の風合いを保持し、取り扱い性に優れた不織布ロールに関する。 The present invention relates to a nonwoven fabric roll that retains the texture of the nonwoven fabric and is excellent in handleability.
近年、不織布の生産効率化に伴い、製造設備の高速化は当然ながら、不織布を加工する工程においては、コストダウンを狙った切替え数低減の為に加工前の不織布ロールの長尺化が要求されている。また、用途に応じて、狭い幅から広い幅までスリットされることは必須である。 In recent years, with the increase in production efficiency of nonwoven fabrics, the speed of manufacturing equipment is naturally increased, and in the process of processing nonwoven fabrics, the length of nonwoven fabric rolls prior to processing is required to reduce the number of switching aimed at cost reduction. ing. In addition, it is essential to slit from a narrow width to a wide width depending on the application.
しかしながら、長尺化は加工設備によっては、ロール径に限界がある為、不織布ロールとしてスリットして巻き取る際にロール径を抑えようと巻取張力を上げることが多い。その結果、不織布ロールは一般に紙管に巻き取られるが(例えば、特許文献1参照)、不織布ロールとしての巻上がり姿は、巻きズレを起こしたり、巻芯である紙管がズレ出ていたり、その紙管が抜けてしまうこともあった。さらに、そういった不織布ロールを用いた加工時においては、蛇行が生じたり、布弛みが多くみられたり、あるいは紙管と不織布のスリップが生じたり、ロール製品として使用に耐えないものがあった。 However, since the roll diameter has a limit on the roll diameter depending on the processing equipment, the winding tension is often increased to suppress the roll diameter when slitting and winding the nonwoven fabric roll. As a result, the nonwoven fabric roll is generally wound around a paper tube (see, for example, Patent Document 1), but the rolled up form of the nonwoven fabric roll causes winding misalignment, or the paper tube as the core is misaligned, The paper tube sometimes came off. Furthermore, during processing using such a nonwoven fabric roll, meandering, a lot of fabric slack, or slippage between the paper tube and the nonwoven fabric occurred, and some roll products could not be used.
不織布も柔らかいものから硬いものと多種多様にあり、特に風合いが良く柔らかいものや表面の滑り性の良い不織布では、巻取時の巻締りにより厚みが潰れてしまい、不織布としての風合いを損ねることが多く、安定に且つ長尺に巻取ることが難題となっている。 There are a wide variety of non-woven fabrics, from soft to hard. Especially, non-woven fabrics with good texture and softness and good slipperiness on the surface may be damaged by winding during winding, and the texture of the nonwoven fabric may be impaired. Many of them are difficult to wind stably and in a long length.
また、不織布ロールの長尺化により、ロール自体の重量も増分される。不織布ロールの梱包後のロールの取り扱いは、運搬積載効率が良い縦置きにするのが一般的である。不織布ロールを縦置きにする際、あるいは縦置きにしたロールの取り扱いの際に、ロールの端面や角に加重を掛けてしまいがちになり、その結果、圧縮力が加わり、変形シワを形成させてしまうことが多い。 Moreover, the weight of roll itself is also increased by elongating a nonwoven fabric roll. The handling of the roll after packing the non-woven roll is generally performed in a vertical orientation with good transport and loading efficiency. When placing a non-woven roll vertically or when handling a roll placed vertically, the end face or corner of the roll tends to be subjected to a load, resulting in a compressive force and the formation of deformed wrinkles. It often ends up.
また、吸湿性を有する不織布や親水化処理などの水溶系の処理剤を用いて処理した不織布などにおいては、高温多湿下に保管された場合、紙管の湿潤が不織布に移行する不具合が生じることもあった。 In addition, in non-woven fabrics that have hygroscopicity or non-woven fabrics that have been treated with a water-soluble treatment agent such as a hydrophilic treatment, there is a problem that the wetness of the paper tube will shift to the non-woven fabric when stored under high temperature and high humidity. There was also.
本発明の課題は、上記の課題を解決して、特に風合いの良い不織布の性能を損ねることなく、安定にかつ長尺に巻き取られた不織布ロールを提供することである。 An object of the present invention is to solve the above-described problems and provide a nonwoven fabric roll wound up stably and in a long length without impairing the performance of a nonwoven fabric having a particularly good texture.
本発明者らは、前記課題を解決する為に種々検討した結果、不織布のスリット巻取時に柔らかく巻きすぎると巻きズレや紙管ズレおよび紙管抜けなどの不具合が発生し、また固く巻きすぎても不織布の幅入りによる巻きズレ、あるいは巻径差が大きくなったりするなどの不具合が発生することから、不織布ロールの巻取安定性には巻密度が重要であることを見出し、本発明をなすに至った。 As a result of various studies to solve the above problems, the present inventors have found that problems such as winding misalignment, paper tube misalignment, and paper tube slippage occur when the nonwoven fabric is wound too softly, and too tightly wound. However, since a problem such as winding deviation due to the width of the nonwoven fabric or a difference in winding diameter occurs, it is found that the winding density is important for the winding stability of the nonwoven fabric roll. It came to.

A wound non-woven roll can be provided. In addition, it is possible to provide a product with good handleability because it is difficult for deformation wrinkles due to compression even after packing.
以下本発明について詳述する。

These webs can be joined using adhesives, low-melting fibers and composite fibers, melt-bonding with a hot melt binder applied during web formation, or entanglement of fibers by needle punching and water flow. However, from the viewpoint of high-speed productivity, it is preferable to join by partial thermocompression bonding. For example, heated embossing that can provide a joint point such as a pinpoint shape, an elliptical shape, a diamond shape, or a rectangular shape. / Can be done through the web between flat rolls.

さらに、熱可塑性繊維には、核剤、難燃剤、無機充填剤、顔料、着色剤、耐熱安定剤および帯電防止剤などを配合したものでもよい。Especially, it is preferable that the polyolefin-type fiber is included from a viewpoint of texture. For example, the fiber which consists of resin, such as a copolymer of polyethylene, a polypropylene, those monomers, and another alpha olefin, is mention | raise | lifted. Polypropylene may be a polymer synthesized by a general Ziegler Natta catalyst, or may be a polymer synthesized by a single site active catalyst typified by metallocene. Other α-olefins have 3 to 10 carbon atoms, and specifically include propylene, 1-butene, 1-pentene, 1-hexane, 4-methyl-1-pentene and 1-octene. It is done. These may be used alone or in combination of two or more. In the case of a combination with an adhesive resin, the content of the adhesive resin is preferably 50% by weight or less in terms of handling and the like. When a composite fiber is used, it may be a core sheath, side-by-side, split fiber or mixed fiber. Further, the fiber shape includes not only ordinary circular fibers but also specially shaped fibers such as crimped fibers and hollow fibers. In particular, it is preferable that the main component is polypropylene from the viewpoint of strength and dimensional stability. Further, the polypropylene component is preferably 75% by weight or more, particularly preferably 90% by weight or more.
Further, the thermoplastic fiber may be blended with a nucleating agent, a flame retardant, an inorganic filler, a pigment, a colorant, a heat stabilizer, an antistatic agent, and the like.
また、不織布を構成する繊維の平均単糸繊度は0.7dtex以上3.5dtex以下が好ましく、さらに好ましくは0.7dtex以上3.0dtex以下である。紡糸安定性の観点から0.7dtex以上であることが好ましく、不織布の風合いや強力の観点から3.5dtex以下であることが好ましい。

From the viewpoint of spinning stability, it is preferably 0.7 dtex or more, and from the viewpoint of the texture and strength of the nonwoven fabric, it is preferably 3.5 dtex or less.
Basis weight of the nonwoven fabric forming the nonwoven fabric roll of the present invention is preferably 8~80g / m 2, is 10 to 50 g / m 2 in terms of texture of the nonwoven fabric more preferred.
本発明の不織布ロールの巻芯に用いる紙管は一般的な紙製の紙管が好ましいが、ポリスチレンまたはポリプロピレンなどの樹脂製でもよい。コストの点から紙製の紙管を用いることが多い。吸湿性を有する不織布や親水化処理が施された不織布などであれば、前記樹脂製のもの、あるいはポリエチレンなどの樹脂でラミネートした疎水性紙管がより好ましい。
また、不織布ロールの巻芯に用いる紙管の外径サイズは、限定されるものではないが、巻き始めは折込みシワなどが入り易い為、巻取容易性の点から、50mm以上が好ましく、物流面での積載効率の点から200mm以下が好ましい。また、紙管の肉厚は4mm未満では巻き潰れが生じやすい為、4mm以上の肉厚が好ましい。The paper tube used for the core of the nonwoven fabric roll of the present invention is preferably a general paper paper tube, but may be made of resin such as polystyrene or polypropylene. In view of cost, a paper tube is often used. As long as it is a non-woven fabric having hygroscopicity or a non-woven fabric subjected to a hydrophilic treatment, a hydrophobic paper tube laminated with a resin or a resin such as polyethylene is more preferable.
In addition, the outer diameter size of the paper tube used for the core of the nonwoven fabric roll is not limited, but it is preferably 50 mm or more from the viewpoint of ease of winding because wrinkles or the like are likely to enter at the beginning of winding. 200 mm or less is preferable from the viewpoint of loading efficiency in terms of surface. Further, if the thickness of the paper tube is less than 4 mm, crushing is likely to occur, and a thickness of 4 mm or more is preferable.
不織布を巻き取る設備は、特に限定されるものではなく、巻取り張力が調整できる、一般的なセンタードライブ式またはサーフェイスドライブ式であってもよい。さらに抑えローラが使用されるものであれば、抑え圧の調整も出来、より安定に巻き取ることが可能な点で好ましい。また、要求される必要な幅へのスリットはシアーカット、スコアーカットあるいはレザーカットなどの方式でもよく、特に限定されるものではない。 The facility for winding the nonwoven fabric is not particularly limited, and may be a general center drive type or surface drive type capable of adjusting the winding tension. Furthermore, if a restraining roller is used, the restraining pressure can be adjusted, which is preferable in that it can be wound more stably. Moreover, the slit to the required required width | variety may be methods, such as a shear cut, a score cut, or a leather cut, and is not specifically limited.
本発明の不織布ロールの巻密度とは不織布の目付×ロール巻長/ロール断面積で算出した値である。巻密度は主に巻き取る際の巻取りテンションによって制御される。巻取りテンションは、一般的に巻取りテンションが低い程、巻き柔らかく、巻取りテンションが高い程、巻き硬くなりやすい。巻取りテンションの範囲としては、巻き取る不織布の特性により異なるが、一般に20〜80N/mの範囲で調整するのが好ましい。不織布ロールの巻密度は0.175〜0.400g/cm3が必要である。0.175g/cm3未満では、不織布ロールの端面の垂直方向に紙管が出てきたりする紙管ズレが発生しやすくなり、完全にロールより抜けることもある。また、ロールの端面が揃わない不織布の巻きズレも発生しやすくなる。巻密度が0.400g/cm3を超えると巻きズレや紙管ズレも起こりやすくなり、さらに巻締りにより不織布の風合いを損ねてしまう。風合いの保持という点から、巻密度は0.175〜0.310g/cm3がより好ましい。特に好ましくは、0.175〜0.250g/cm3である。The winding density of the nonwoven fabric roll of the present invention is a value calculated by the basis weight of nonwoven fabric × roll winding length / roll cross-sectional area. The winding density is controlled mainly by the winding tension at the time of winding. In general, the lower the winding tension, the softer the winding tension, and the higher the winding tension, the harder the winding tension. The range of the winding tension varies depending on the characteristics of the nonwoven fabric to be wound, but is generally preferably adjusted in the range of 20 to 80 N / m. The winding density of the nonwoven fabric roll needs to be 0.175 to 0.400 g / cm 3 . If it is less than 0.175 g / cm 3 , paper tube misalignment, in which the paper tube comes out in the direction perpendicular to the end face of the nonwoven fabric roll, is likely to occur, and it may come off the roll completely. Moreover, the winding deviation of the nonwoven fabric in which the end surfaces of the rolls are not aligned easily occurs. When the winding density exceeds 0.400 g / cm 3 , winding misalignment and paper tube misalignment are likely to occur, and the texture of the nonwoven fabric is impaired by tightening. From the viewpoint of maintaining the texture, the winding density is more preferably 0.175 to 0.310 g / cm 3 . Particularly preferably, it is 0.175 to 0.250 g / cm 3 .
上記巻密度を考慮しながら、不織布ロールの内層と外層との厚さの比(内層厚さ/外層厚さ)を制御することで、さらに安定な巻取りが可能となる。不織布ロールの内層と外層の厚さの比は、巻取り時の巻取りテンションで調整を行うことも可能であるが、例えば抑えローラーを併用する場合は、巻き始めから巻き終りになるほど、抑え圧を下げて、調整することも可能である。不織布ロールの内層、外層とは不織布ロール半径から紙管半径を差し引いた距離の紙管側10%以内を内層とし、不織布ロール最外側10%以内を外層とする。内層の厚さおよび外層の厚さは、上記各範囲内の位置にある不織布一枚の厚さを示す。安定に巻取りが可能な不織布ロールの内層と外層との厚さの比(内層厚さ/外層厚さ)は0.65〜1.00が好ましい。この厚さの比が0.65未満では、不織布ロールの端面の垂直方向に紙管が出てきたりする紙管ズレが発生しやすくなり、完全にロールより抜けることもある。また、ロールの端面が揃わない不織布の巻きズレも発生しやすくなる。この厚さの比が1.00を超えると巻きズレや紙管ズレも起こりやすくなり、巻締りにより不織布の風合いを損ねてしまう。風合いの保持という点から、この厚さの比は0.80〜1.00がさらに好ましく、0.85〜0.96が特に好ましい。 Controlling the thickness ratio (inner layer thickness / outer layer thickness) between the inner layer and the outer layer of the nonwoven fabric roll while taking the above-mentioned winding density into consideration enables further stable winding. The ratio of the thickness of the inner layer to the outer layer of the nonwoven fabric roll can be adjusted by the winding tension at the time of winding.For example, when using a suppression roller, the pressure decreases as the winding starts and ends. It is also possible to adjust by lowering. The inner layer and the outer layer of the nonwoven fabric roll are defined as the inner layer within 10% of the paper tube side of the distance obtained by subtracting the radius of the paper tube from the radius of the nonwoven fabric roll, and the outer layer within the outermost 10% of the nonwoven fabric roll. The thickness of the inner layer and the thickness of the outer layer indicate the thickness of one nonwoven fabric at a position within the above ranges. The thickness ratio (inner layer thickness / outer layer thickness) of the inner layer and outer layer of the nonwoven fabric roll that can be stably wound is preferably 0.65 to 1.00. If the ratio of thickness is less than 0.65, a paper tube misalignment in which the paper tube comes out in the direction perpendicular to the end face of the nonwoven fabric roll is likely to occur, and it may come off the roll completely. Moreover, the winding deviation of the nonwoven fabric in which the end surfaces of the rolls are not aligned easily occurs. If the thickness ratio exceeds 1.00, winding deviation and paper tube deviation are likely to occur, and the texture of the nonwoven fabric is impaired by winding. From the viewpoint of maintaining the texture, the thickness ratio is more preferably 0.80 to 1.00, and particularly preferably 0.85 to 0.96.
本発明の不織布ロールのロール幅は特に限定しないが、巻取安定性の点で60mm以上のロール幅が好ましい。80mm以上がさらに好ましく、100mm以上が特に好ましい。
本発明の不織布ロールのロール径は、長尺のロールと言う意味では、30cm以上からなるロール径が妥当と言える。すなわち、ロール径30cmを超えない範囲は本発明の課題解決手段を考慮せずとも容易に巻き取ることが可能である。より好ましくは、50cm以上、さらに好ましくは、70cm以上である。巻取り安定性の点で150cm以内の範囲が好ましい。The roll width of the nonwoven fabric roll of the present invention is not particularly limited, but a roll width of 60 mm or more is preferable from the viewpoint of winding stability. 80 mm or more is more preferable, and 100 mm or more is particularly preferable.
The roll diameter of the nonwoven fabric roll of the present invention can be said to be a roll diameter of 30 cm or more in the sense of a long roll. That is, the range not exceeding the roll diameter of 30 cm can be easily wound without considering the problem solving means of the present invention. More preferably, it is 50 cm or more, More preferably, it is 70 cm or more. The range within 150 cm is preferable in terms of winding stability.
本発明の不織布ロールは巻締り程度を表すロールスリップ強度が少なくとも8.0N・m以上が好ましい。10.0N・m以上がさらに好ましく、特に好ましくは12.0N・m以上である。ロールスリップ強度が8.0N・m未満では紙管ズレや紙管抜けが起こりやすく、安定なロール形態を保持しにくい。ロールスリップ強度は巻取り時に巻取りテンションで調整を行うことも可能であるが、例えば抑えローラーを併用する場合は、巻き始めから巻き終りになるほど、抑え圧を下げて、調整することも可能である。
不織布の風合いを保持していれば、ロールスリップ強度は大きければ大きい程好ましいが、巻締り過ぎない目安として150N・m以内が好ましく、100N・m以内が好ましい。The nonwoven fabric roll of the present invention preferably has a roll slip strength representing the degree of tightening of at least 8.0 N · m. It is more preferably 10.0 N · m or more, and particularly preferably 12.0 N · m or more. When the roll slip strength is less than 8.0 N · m, paper tube misalignment and paper tube slip are likely to occur, and it is difficult to maintain a stable roll form. The roll slip strength can be adjusted with the winding tension at the time of winding.For example, when using a suppression roller, it is also possible to adjust the roll slip strength by decreasing the suppression pressure from the beginning of winding to the end of winding. is there.
If the texture of the nonwoven fabric is maintained, the roll slip strength is preferably as large as possible. However, it is preferably 150 N · m or less, and preferably 100 N · m or less, as a guideline for preventing excessive tightening.
本発明の不織布ロールの巻きズレは0〜8mmであることが好ましい。巻きズレとは、不織布ロールを形成する際に不織布がロールの端面に対して揃わずに巻かれた状態を言う。すなわち、巻きズレの距離がある程、不安定に巻かれていることを示す。不織布ロールの加工工程での安定性の点で巻きズレは5mm以内がさらに好ましい。
本発明の不織布ロールの紙管ズレは0〜8mmであることが好ましい。紙管ズレとは、不織布ロールを形成する際に紙管が不織布ロール端面に対して揃わずに抜け出ている状態を言う。すなわち、紙管ズレの距離がある程、不安定に巻かれていることを示す。不織布ロールの加工工程での安定性の点で紙管ズレは5mm以内がさらに好ましい。
本発明の不織布ロールの巻径差は0〜8mmであることが好ましい。巻径差とは、不織布ロールの表面の凹凸差を示し、幅方向内の最大径と最小径の差である。すなわち、巻径差が大きい程、不安定に巻かれていることを示す。不織布ロールの加工工程での安定性の点で巻径差は5mm以内がさらに好ましい。The winding deviation of the nonwoven fabric roll of the present invention is preferably 0 to 8 mm. Winding misalignment refers to a state in which the nonwoven fabric is wound without being aligned with the end face of the roll when the nonwoven fabric roll is formed. That is, as the winding deviation distance increases, the winding is unstable. The winding deviation is more preferably within 5 mm from the viewpoint of stability in the processing step of the nonwoven fabric roll.
The paper tube deviation of the nonwoven fabric roll of the present invention is preferably 0 to 8 mm. Paper tube misalignment refers to a state where the paper tube is not aligned with the end surface of the nonwoven fabric roll when forming the nonwoven fabric roll. That is, the more the paper tube misalignment is, the more unstable the winding is. The deviation of the paper tube is more preferably within 5 mm from the viewpoint of stability in the processing step of the nonwoven fabric roll.
It is preferable that the roll diameter difference of the nonwoven fabric roll of this invention is 0-8 mm. The difference in the winding diameter indicates the unevenness of the surface of the nonwoven fabric roll, and is the difference between the maximum diameter and the minimum diameter in the width direction. That is, the larger the winding diameter difference, the more unstable the winding. The winding diameter difference is more preferably within 5 mm from the viewpoint of stability in the processing step of the nonwoven fabric roll.
本発明の不織布ロールを形成する不織布の表面摩擦係数MIUは0.050〜0.400であることが好ましい。表面摩擦係数MIUが0.400を超えると、工程中のロールとられが生じやすくなったり、不織布ロールの巻締まりが起きやすくなったりする。また、表面摩擦係数MIUが0.050未満であると、工程中で滑りによる蛇行やロールとられが生じやすくなる。表面摩擦係数MIUは0.100〜0.350がさらに好ましく、0.100〜0.300が特に好ましい。 The surface friction coefficient MIU of the nonwoven fabric forming the nonwoven fabric roll of the present invention is preferably 0.050 to 0.400. When the surface friction coefficient MIU exceeds 0.400, it becomes easy to cause the roll to be taken during the process or to tighten the nonwoven fabric roll. In addition, when the surface friction coefficient MIU is less than 0.050, meandering or rolling due to slipping is likely to occur during the process. The surface friction coefficient MIU is more preferably 0.100 to 0.350, and particularly preferably 0.100 to 0.300.
本発明の不織布ロールは梱包後の取り扱い時に圧縮加重による変形シワや傷などの不具合を発生させない為に、不織布ロールの両端面、あるいは複数並べた不織布ロールの最両端面を養生シートで抑え、フィルムで包装することが好ましい。複数並べるとは、ロールの芯が合うように不織布ロールの端面と端面を合わせるように並べることである。複数並べる際は同一ロール径のものを並べるのが一般的である。最両端面とは、複数並べた不織布ロールの両端に配置されたロールの外側となる端面のことであり、梱包する際には、最両端面を養生シートで養生してもよい。 Since the nonwoven fabric roll of the present invention does not cause defects such as deformation wrinkles or scratches due to compression load during handling after packing, the both ends of the nonwoven fabric roll, or the outermost ends of a plurality of arranged nonwoven fabric rolls are suppressed with a curing sheet, and a film It is preferable to package with. Arranging a plurality of layers means arranging the end surfaces of the nonwoven fabric rolls so that the end surfaces are aligned so that the cores of the rolls are aligned. When arranging a plurality, it is common to arrange the same roll diameter. The outermost end surfaces are end surfaces that are outside the rolls arranged at both ends of a plurality of non-woven fabric rolls arranged. When packing, the outermost end surfaces may be cured with a curing sheet.
養生シートは特に限定されるものではなく、ポリスチレンまたはポリプロピレンなどの熱可塑性樹脂製のものでもよく、紙製の厚紙またはダンボールでもよい。養生シートのサイズは、不織布ロールのロール径サイズに合わせるのが一般的である。不織布ロールの梱包後の取り扱い時に、運搬積載効率などの点から、ロールが縦積みにされることが多い。このため、少なくとも下面となるロール端面の養生シートの径は、ロール径±10mmの範囲が、ロールの角部の養生効果が大きく好ましい。また、包装フィルムの破れ防止などの点から、−10mm〜+5mmの範囲がさらに好ましい。 The curing sheet is not particularly limited, and may be made of a thermoplastic resin such as polystyrene or polypropylene, or may be paper cardboard or cardboard. The size of the curing sheet is generally matched to the roll diameter size of the nonwoven fabric roll. When handling non-woven rolls after packing, the rolls are often stacked vertically in terms of transport and loading efficiency. For this reason, at least the diameter of the curing sheet on the roll end surface serving as the lower surface is preferably in the range of roll diameter ± 10 mm because the curing effect of the corners of the roll is large. Moreover, the range of -10 mm-+5 mm is more preferable from points, such as a tear of a packaging film.
包装に用いるフィルムは特に限定されるものではないが、不織布ロール保管時に温湿度などの環境変化に影響されにくい不透湿性を有したポリエチレンなどのポリオレフィン系の熱可塑性樹脂フィルムが好ましい。また、不織布ロールの梱包は、手包装でも自動梱包機を用いて行ってもよい。不織布ロールを固定し易い点でシュリンク性のあるフィルムで巻き付けて包装するのが好ましい。さらに、前述の通り取り扱い時に、ロールが縦積みにされることが多い為、少なくとも下面となる角部は、上面よりも多く巻き付けることがロール角部の養生効果が大きく好ましい。 The film used for the packaging is not particularly limited, but a polyolefin-based thermoplastic resin film such as polyethylene having moisture impermeability which is not easily affected by environmental changes such as temperature and humidity during storage of the nonwoven fabric roll is preferable. Moreover, you may pack a nonwoven fabric roll using an automatic packing machine by hand packaging. It is preferable that the nonwoven fabric roll is wrapped and wrapped with a shrinkable film in terms of easy fixing. Furthermore, since the rolls are often stacked vertically during handling as described above, it is preferable that at least the corners which are the lower surfaces are wound more than the upper surfaces because the curing effect of the roll corners is large.
本発明の不織布ロールを形成する不織布は限定されるものではないが、特に風合いの良い不織布に対して、安定に巻取られた不織布ロールとして、また梱包後の取り扱いに優れた不織布ロールとして有効である。
風合いの良い不織布としては、例えば、不織布に親水化剤が付着されている不織布や柔軟化剤が含有されている不織布などがある。Although the nonwoven fabric which forms the nonwoven fabric roll of the present invention is not limited, it is particularly effective as a nonwoven fabric roll wound up stably and a nonwoven fabric roll excellent in handling after packing, especially for a nonwoven fabric having a good texture. is there.
Examples of the non-woven fabric having a good texture include a non-woven fabric in which a hydrophilic agent is attached to the non-woven fabric and a non-woven fabric containing a softening agent.
不織布に付着する親水化剤としては、人体への安全性および工程での安全性等を考慮して、高級アルコール、高級脂肪酸、アルキルフェノール等にエチレンオキサイドを付加した非イオン系活性剤、アルキルフォスフェート塩およびアルキル硫酸塩等のアニオン系活性剤等の単独あるいは混合物等が好ましく用いられる。
また、親水化剤の付着量は、要求される性能によって異なるが、例えば衛生材料用としては、通常、繊維に対して0.1〜1.0wt%の範囲が好ましく、性能の点から0.2〜0.6wt%がさらに好ましい。As a hydrophilizing agent that adheres to the nonwoven fabric, in consideration of safety to the human body and safety in the process, nonionic active agents in which ethylene oxide is added to higher alcohols, higher fatty acids, alkylphenols, etc., alkyl phosphates A single or mixture of anionic active agents such as salts and alkyl sulfates is preferably used.
Moreover, although the adhesion amount of a hydrophilizing agent changes with performance requested | required, for example, for sanitary materials, the range of 0.1-1.0 wt% is preferable normally with respect to a fiber, and it is 0. 2 to 0.6 wt% is more preferable.
親水化剤を塗布する方法としては、通常、希釈した親水化剤を用いて、浸漬法、噴霧法およびコーティング(キスコーター、グラビアコーター)法等の既存の方法が採用でき、その際の乾燥方法としては、対流伝熱、伝導伝熱および放射伝熱等を利用した既知の方法が採用でき、熱風や赤外線による乾燥あるいは熱接触による乾燥方法等を用いることもできる。 As a method of applying the hydrophilizing agent, existing methods such as a dipping method, a spraying method, and a coating (kiss coater, gravure coater) method can be generally employed using a diluted hydrophilizing agent, and as a drying method at that time Can be a known method using convective heat transfer, conduction heat transfer, radiant heat transfer, or the like, and can also be a drying method using hot air or infrared rays or a drying method using thermal contact.
また、不織布に含有する柔軟化剤としては、たとえば、エステル化合物であることが好ましく、より好ましくは、3〜6価のポリオールとモノカルボン酸とのエステル化合物が用いられる。
3〜6価のポリオールとしては例えばグリセリンおよびトリメチロールプロパン等の3価のポリオール、ペンタエリスリトール、グルコース、ソルビタン、ジグリセリンおよびエチレングリコールジグリセリルエーテル等の4価のポリオール、トリグリセリンおよびトリメチロールプロパンジグリセリルエーテル等の5価のポリオール、ソルビトール、テトラグリセリンおよびジペンタエリスリトール等の6価のポリオール等が挙げられる。Moreover, as a softening agent contained in a nonwoven fabric, it is preferable that it is an ester compound, for example, More preferably, the ester compound of a 3-6 valent polyol and monocarboxylic acid is used.
Examples of the trivalent to hexavalent polyols include trivalent polyols such as glycerin and trimethylolpropane, tetravalent polyols such as pentaerythritol, glucose, sorbitan, diglycerin and ethylene glycol diglyceryl ether, triglycerin and trimethylolpropane diene. Examples include pentavalent polyols such as glyceryl ether, hexavalent polyols such as sorbitol, tetraglycerin, and dipentaerythritol.
モノカルボン酸としては例えばオクタン酸、ドデカン酸、テトラデカン酸、オクタデカン酸、ドコサン酸、ヘキサコサン酸、オクタデセン酸、ドコセン酸およびイソオクタデカン酸等のモノカルボン酸、シクロヘキサンカルボン酸等の脂環式モノカルボン酸、安息香酸およびメチルベンゼンカルボン酸等の芳香族モノカルボン酸、ヒドロキシプロピオン酸、ヒドロキシオクタデカン酸およびヒドロキシオクタデセン酸等のヒドロキシ脂肪族モノカルボン酸、並びにアルキルチオプロピオン酸等の含イオウ脂肪族モノカルボン酸等が挙げられる。 Examples of the monocarboxylic acid include octacarboxylic acid, dodecanoic acid, tetradecanoic acid, octadecanoic acid, docosanoic acid, hexacosanoic acid, octadecenoic acid, docosenoic acid and isooctadecanoic acid, and other alicyclic monocarboxylic acids such as cyclohexanecarboxylic acid. Aromatic monocarboxylic acids such as benzoic acid and methylbenzenecarboxylic acid, hydroxyaliphatic monocarboxylic acids such as hydroxypropionic acid, hydroxyoctadecanoic acid and hydroxyoctadecenoic acid, and sulfur-containing aliphatic monocarboxylic acids such as alkylthiopropionic acid Etc.
柔軟化剤として使用されるエステル化合物は特に単一成分である必要はなく、2種以上の混合物でもよい。天然物由来の油脂類を使用してもよい。ただし、不飽和脂肪酸を含むエステル化合物は酸化されやすく、溶融紡糸時に酸化劣化しやすいため、好ましくは飽和の脂肪族モノカルボン酸または芳香族モノカルボン酸が好ましい。天然物由来の油脂類を使用する場合は原料油に比べて、無臭で安定なため、水素添加したエステル化合物が好ましく用いられる。 The ester compound used as the softening agent need not be a single component, and may be a mixture of two or more. Oils and fats derived from natural products may be used. However, since ester compounds containing unsaturated fatty acids are easily oxidized and easily deteriorated during melt spinning, saturated aliphatic monocarboxylic acids or aromatic monocarboxylic acids are preferred. When natural oils and fats are used, hydrogenated ester compounds are preferably used because they are odorless and stable compared to raw material oils.
エステル化合物はモノカルボン酸の分子量が比較的大きく、親油性が高いことが重要である。ポリオレフィン系繊維の場合、親油性が高いことにより、非晶部に入り込み結晶化を阻害して非晶領域が増加するため、柔軟性を得ることができる。
エステル化合物の含有率は熱可塑性繊維に対し、0.3wt%以上5.0wt%以下が好ましい。該エステル化合物は少量の添加でも曲げ柔軟度や滑りやすさが著しく向上し、含有量を増やしても含有量に見合った性能向上は見られない。このことから、紡糸性および発煙性を加味し、5.0wt%以下が適切であり、さらに好ましくは0.5wt%〜3.5wt%、特に好ましくは0.5wt%〜2.0wt%である。It is important that the ester compound has a relatively high molecular weight of monocarboxylic acid and high lipophilicity. In the case of a polyolefin-based fiber, since it has high lipophilicity, it enters the amorphous part and inhibits crystallization to increase the amorphous region, so that flexibility can be obtained.
The content of the ester compound is preferably 0.3 wt% or more and 5.0 wt% or less with respect to the thermoplastic fiber. Even when the ester compound is added in a small amount, the bending flexibility and slipperiness are remarkably improved, and even if the content is increased, the performance improvement corresponding to the content is not observed. From this, considering the spinnability and smoke generation, 5.0 wt% or less is appropriate, more preferably 0.5 wt% to 3.5 wt%, particularly preferably 0.5 wt% to 2.0 wt%. .
本発明の不織布ロールは安定に巻き取られ、その取り扱いや加工適正にも優れている為、特に風合いの要求される使い捨てオムツ、生理用ナプキンおよび失禁パットなどの衛生材料用途として好ましい。また、例えばマスク、カイロ、テープ基布、防水シート基布、貼布薬基布、救急絆基布、包装材、ワイプ製品、医療用ガウン、包帯、衣料およびスキンケア用シートなどの用途向けの不織布ロールとして使用することができる。 Since the nonwoven fabric roll of the present invention is stably wound and excellent in handling and processing suitability, it is particularly preferable for use as sanitary materials such as disposable diapers, sanitary napkins and incontinence pads that require a texture. In addition, non-woven fabrics for applications such as masks, warmers, tape base fabrics, tarpaulin base fabrics, patch base fabrics, first aid adhesive base fabrics, packaging materials, wipe products, medical gowns, bandages, clothing and skin care sheets Can be used as a roll.

In addition, the evaluation method of each characteristic is as follows.
1. Average single yarn fineness (dtex)
The nonwoven fabric was cut off by 1 cm square at an arbitrary location so that there were 5 locations in the width direction of the nonwoven fabric to be measured, and the fiber diameter of the nonwoven fabric surface layer was measured at 20 points using a microscope, and the fineness was calculated from the average value. .

A friction element and a sample in which ten contacts obtained by bending a piano wire with a diameter of 0.5 mm into a U-shape are arranged, and a standard measurement condition (SENS: H, SPEED: 1 mm / sec, pressure bonding pressure between the sample and the friction element: Friction at 50 gf) and MIU was measured. The vertical (MD) direction is measured three times, and the average is shown. A smaller value means less frictional resistance.
3.ロールスリップ強度(N・m)

Insert a rubber roll slip fixed shaft (paper tube inner surface contact rubber length 5 cm) into the paper tube of the non-woven roll, insert air into the shaft, apply a certain pressure, and tightly fix the inside of the paper tube and rubber. It was. Next, using a torque wrench, the roll slip fixed shaft was turned in the roll winding direction, and the strength when the paper tube was rotated was measured. That is, the roll slip strength indicates the degree of tightening of the nonwoven fabric around the paper tube. The lower the roll slip strength, the easier the paper tube slippage and paper tube slippage occur, and the paper tube during unwinding in the processing step. This means that problems such as slipping of the nonwoven fabric are likely to occur.
4.不織布ロールのロール径(cm)
不織布ロールを転がすようにして床面に置き、床面上から垂直に不織布ロールの端面中心を通して、不織布ロールの最上部までの距離を、定規を用いて測定した。これを両端面で測定し、さらにロールの3分の1を転がし、同様に測定、さらにロールの3分の1を転がし、同様に測定した。片側の端面で3点ともう片側の端面で3点測定した計6点の平均値を不織布ロールのロール径とした。4. Roll diameter of non-woven roll (cm)

The thickness of the inner layer and the thickness of the outer layer indicate the thickness of a single nonwoven fabric at a position within the above ranges. Immediately after unwinding the nonwoven fabric roll, the thickness of the nonwoven fabric located in the range of the inner layer and the outer layer was arbitrarily measured with a peacock type thickness meter (100 g / cm 2 ), and the average thickness was calculated.
6.巻密度(g/cm3)
不織布ロールの巻密度(g/cm3)は、不織布の目付×ロール巻長/ロール断面積で算出した値である。不織布の目付は、上記厚さ測定時と同時に、内層および外層において、不織布ロール1m長を任意に3枚切取り重量を測定し、その値を(定規にて測定したロール幅×1m長×3枚)の面積値で除した。また、不織布のロール巻長は巻取機に設置した測長カウンターで測定した。さらに不織布のロール断面積は、上記4にて測定したロール径から断面積を求め、その値から用いた紙管外径断面積を差し引いた値とした。6). Winding density (g / cm 3 )
The winding density (g / cm 3 ) of the nonwoven fabric roll is a value calculated by the basis weight of the nonwoven fabric × roll winding length / roll cross-sectional area. The fabric weight of the nonwoven fabric was measured at the same time as the above-mentioned thickness measurement by arbitrarily measuring the weight of three nonwoven fabric rolls of 1 m in the inner layer and outer layer, and measuring the value (roll width measured by a ruler × 1 m length × 3 sheets) ) Divided by the area value. The roll length of the nonwoven fabric was measured with a length measuring counter installed in a winder. Furthermore, the roll cross-sectional area of the nonwoven fabric was determined by obtaining the cross-sectional area from the roll diameter measured in 4 above and subtracting the paper tube outer diameter cross-sectional area used from that value.
