Description of the Invention: [Technical Field of the Invention] The present invention relates to a non-woven fabric roll that maintains a non-woven fabric. [Prior Art] In recent years, as the production of non-woven fabrics has become more efficient, it is a matter of course that high-speed manufacturing equipment is required, and in order to reduce the number of replacements to reduce costs in the process of processing non-woven fabrics, it is required to roll the non-woven fabric strips before processing. Chemical. Also, it needs to be cut into a narrow width to a wide width depending on the application. However, the strip length has a limit on the diameter of the reel due to the difference in the garnishing equipment. Therefore, if the diameter of the reel is to be controlled when slitting and winding, the winding tension is increased. The non-woven fabric roll is usually taken up on the paper tube (10). For example, referring to Patent Document 1), there is also a winding offset as a non-woven fabric roll, or a winding core, a chip offset, or the like. The case of paper tube detachment. Further, when such a non-woven fabric roll is used for processing, curling occurs, or the cloth is loosened in a plurality of places, or the paper tube and the non-woven fabric are slid, and the roll product is not durable. = cloth also has a wide variety of non-woven fabrics from soft to hard, and has a good feel and a soft non-woven fabric or a smooth surface, which is thinned by the winding up during winding, and the damage is not felt. 'So the stable and long stripping becomes a problem. Moreover, by the strip of the non-woven fabric, the weight of the reel itself is also placed upright. When the non-woven fabric roll is placed upright, or when the roll is placed upright, the end face or the corner of the roll is often loaded, and as a result, the roll is subjected to compressive force, in many cases Formed wrinkles. Further, a non-woven fabric having a hygroscopic property or a non-woven fabric treated with a water-soluble treatment agent such as a hydrophilization treatment may have a problem that the wetness of the paper tube is transferred to the non-woven fabric when stored under high temperature and high humidity. [Prior Art] [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open Publication No. 2004-150008 [Draft] [Problems to be Solved by the Invention] An object of the present invention is to solve the above problems, and in particular to provide a The non-woven fabric roll is stably and longly wound without damaging the performance of the non-woven fabric having a good hand feeling. [Means for Solving the Problems] The inventors of the present invention conducted various studies to solve the above problems, and as a result, it has been found that when the non-woven fabric is cut and wound, if the winding is too loose, winding deviation or paper tube deviation occurs. If the paper tube is detached, the winding is too tight, and the winding deviation due to the shrinkage of the nonwoven fabric is not generated, or the winding diameter difference is increased. Therefore, the winding stability of the non-woven fabric roll is rolled. Density is important to complete the present invention. That is, the present invention is as follows.

(#3) as described above 1 or 2 The non-woven fabric roll of the present invention is characterized in that the diameter of the roll of the non-woven fabric roll is 30 cm or more, and the roll strength of the roll of the roll is 8.0 N·m or more. (4) As in any of the above items 1 to 3 The non-woven fabric roll of the present invention is characterized in that the winding offset is 〇~8 mm. (5) The non-woven fabric roll according to any one of the above items 1 to 4, characterized in that the paper tube offset is 〇~8 mm (6) The non-woven fabric roll according to any one of the above items 1 to 5, wherein the roll diameter difference is 0 to 8 mm. (7) The non-woven fabric roll according to any one of the above items 1 to 6, It is characterized in that the surface friction coefficient MIU of the non-woven fabric is 〇〇5〇~〇4〇〇. (8) The non-woven fabric roll according to any one of the above items 1 to 7. The non-woven fabric roll of any one of the above items 1 to 8 is pressed against the both ends of the non-woven fabric roll by a curing sheet, or plural The non-woven fabric roll of any one of the above items 1 to 9 is characterized in that the non-woven fabric contains thermoplastic fibers. (11) As in the above 10 items, the non-woven fabric rolls are arranged in a film. The non-woven fabric roll is characterized in that the thermoplastic fiber contains at least a polyolefin-based fiber. 163669.doc 201250077 (12) The non-woven fabric roll of the above U, characterized in that the polyolefin-based fiber contains at least polypropylene-based fibers. The non-woven fabric roll according to any one of the above items 1 to 12, wherein the non-woven fabric comprises a long-fiber nonwoven fabric. (14) The non-woven fabric roll according to any one of items 1 to 13 above is used for a sanitary material. [Effects of the Invention] According to the present invention, in particular, even a non-woven fabric having a good hand feeling and a soft non-woven fabric or a surface smoothness can provide a winding which is relatively tight during winding, and which is not damaged as a non-woven fabric. In the case of the hand, it is stably and slit into a long strip and is wound into a non-woven fabric roll. Moreover, it is not easy to form a deformed wrinkle due to compression after the bale is bundled, and the operability is good. The present invention will be described in detail below. The method for producing the nonwoven fabric forming the nonwoven fabric roll of the present invention is not particularly limited, and may be obtained by a so-called carding method or a papermaking method. Short fiber. In the case of the domain dimension, the H-cut method or the airflow method is made into a fiber (web), and the heating is carried out until (four) the temperature at which the fiber is dazzled, so that the fiber is made into a non-woven fabric at the intersection of the hot material. As a method of the heat, the hot air method, the rich light roll method, the emboss roll method, the ultrasonic method, or the like can be used. In terms of productivity, the fibers constituting the nonwoven fabric are preferably continuous and preferably long fibers. For example, the continuous filament obtained by spinning the molten I63669.doc 201250077 is formed into a fiber web by a spunbonding method (S), and the fiber web is joined to form a nonwoven fabric. Further, a fiber web formed by melt-spinning by a melt blow method (μ) may be sprayed on a fiber web formed by the spunbonding method (8) to obtain a laminated fiber web. Regarding the state of the buildup, in terms of productivity, the stackable layer may be SS SSSS ' or may be laminated to the webs by means of SM, SMS, SMMS or SMSMS, or may be bonded and used with an adhesive. The fibers are fused by the dots or the composite fibers, and the hot-melt adhesive is dispersed in the process of forming the fiber web to be melt-bonded, or the fibers are interlaced by a needle-like needle punch, a water flow, or the like, but the high-speed productivity is compared. Preferably, the bonding is carried out by partial thermocompression bonding, for example, by passing the fiber web between the embossing roller/smoothing roller which can impart a needle-like ellipse, diamond shape or rectangular shape and the heated embossing roller/smooth roller And joined. The heat-pressing area ratio of the partial thermocompression bonding is preferably 5 to 40% Å or more preferably 5 to 25 Å/Å in terms of strength and flexibility. The fiber constituting the nonwoven fabric is preferably a thermoplastic fiber, but it is preferably a fiber having no adhesiveness in terms of stability in processing and extraction. As the thermoplastic fiber, for example, polyolefin fibers such as ethylene fiber, polypropylene fiber, and copolymerized polypropylene; polyethylene terephthalate fiber, polybutylene terephthalate, and polynaphthalene m fiber; Copolymerized poly-anthratic fibers such as polystyrene; polyamine fibers such as nylon-6 fiber, nylon_66 fiber and copolymerized nylon; and polylactic acid, polybutylene succinate and polyethylene succinate Biodegradable fiber, etc. Among them, from the viewpoint of hand feeling, it is preferable to contain a polyolefin fiber. For example, a fiber 1 (four) comprising a polyethylene, a propylene, and a resin such as a copolymer of the monomer and another α-ene 163669.doc 201250077 hydrocarbon may be used as a conventional Zigler-Nattacatalyst. Further, the polymer synthesized may be a polymer synthesized by using a single-site active catalyst typified by a metallocene. The other α-olefins refer to those having a carbon number of 3 to 1 Å, (4), 1-butadiene, ..., hexane, and 4 _methyl. These may be used alone or in combination with two types of resins in combination with a resin having adhesiveness. The content of the resin having adhesiveness may be 5% by weight or less. In the case of composite fibers, the temple can be made into a type of side-by-side type, side-by-side type, split type or mixed type 3L. Further, the fiber shape is not only a normal circular fiber but also a special shape such as a crimped fiber or a hollow fiber. In particular, in terms of strength and dimensional stability, it is preferred that the poly(propylene) component as the main component is preferably 75% by weight or more, and more preferably 9% by weight or more. Further, a nucleating agent, a flame retardant, an inorganic filler, a pigment, a coloring agent, a heat-resistant stabilizer, an antistatic agent, and the like may be blended in the thermoplastic fiber.

From the viewpoint of spinning stability, t is Preferably, it is 0.7 dtex or more, and is preferably 35 or less from the viewpoint of the texture or strength of the non-woven fabric. The basis weight of the non-woven fabric forming the nonwoven fabric roll of the present invention is preferably 8 to 8 〇 2, and the texture of the non-woven fabric is not preferable. More preferably, it is preferably 10 to 50 g/m2. The paper tube used in the roll of the nonwoven fabric of the present invention is preferably a conventional paper tube but may be polystyrene or polypropylene. Resin manufacturer. 163669.doc 201250077 In this respect, a paper paper tube is often used. If it is a non-woven fabric having hygroscopicity or a non-woven fabric subjected to hydrophilization treatment, it is more preferably the above-mentioned resin maker's layer or layer. A hydrophobic paper tube which is pressed with a resin such as polyethylene. Further, the outer diameter of the paper tube used for the core of the non-woven fabric roll is not limited to 'but the folding wrinkles are easily generated at the start of winding, so the winding is performed. In terms of easiness, it is preferably 50 mm or more. From the viewpoint of the loading efficiency, it is preferably 200 mm or less. Further, if the wall thickness of the paper tube is less than 4 mm, the winding collapse is likely to occur, so that it is preferably a wall thickness of 4 or more claws. The apparatus is not particularly limited, and may be a conventional center drive type or a surface drive type that can adjust the take-up tension. Further, if the device is a press roll, the press can be adjusted. The pressure can be more stably wound up. In addition, the required width for slitting can be shear cut, slit (^(3) generation cut) or razor cut. The roll density of the non-woven fabric rolls of the present invention is a value calculated from the basis weight of the non-woven fabric, the roll length/reel cross-sectional area, and the roll density is mainly obtained by the roll of the roll. With regard to the tension of the take-up, the lower the tension of the take-up, the looser the winding, and the higher the take-up tension, the easier the winding is. The range of the take-up tension is based on the characteristics of the non-woven fabric being taken up. And the difference 'usually better at 20 Adjustable within the range of 80 N/m. The roll density of the non-woven roll must be 0.175~0.400 g/cm3. If it is less than 175 g/cm3, the paper tube deviation is easy to occur, for example, the paper tube is not in the roll. The end face is exposed in the vertical direction, and there is also a case where the paper tube is completely detached from the reel 163669.doc 201250077. It is also easy to cause the end face of the reel to be misaligned, that is, the non-woven fabric is offset. The roll density exceeds 0.400 g/ The cm3 is also liable to cause a winding offset or a paper tube offset 'and damages the feel of the non-woven fabric due to the winding. The roll density is more preferably 0 to 175 to 0.3 10 g/cm 3 in terms of maintaining the hand feeling. More preferably, it is 0.175 to 0.250 g/cni3. By considering the above-mentioned roll density and controlling the thickness ratio (inner layer thickness/outer layer thickness) of the inner layer to the outer layer of the nonwoven fabric roll, it is more stably wound up. The thickness ratio of the inner layer to the outer layer of the non-woven fabric roll can also be adjusted by the take-up tension at the time of winding. However, for example, when the pressing roll is used in combination, the pressing can be gradually lowered as the winding ends from the start of winding. Adjust with pressure. The inner layer and the outer layer of the non-woven fabric roll are made up of 10% of the paper tube side from the distance of the non-woven fabric roll minus the paper tube radius as the inner layer 'the outermost portion of the non-woven fabric roll within 10% of the outer layer as the outer layer. . The thickness of the inner layer and the thickness of the outer layer indicate the thickness of a piece of non-woven fabric located within each of the above ranges. The thickness ratio (inner layer thickness/outer layer thickness) of the inner layer to the outer layer of the non-woven fabric roll which can be stably wound up is preferably from 0 65 to 1.00. If the thickness ratio is less than 0.65 ', the paper tube deviation is liable to occur, for example, the paper tube is exposed in the vertical direction of the end surface of the nonwoven fabric roll, and the paper tube is completely detached from the roll. Moreover, it is also easy to produce a winding offset in which the end faces of the reels are not aligned, i.e., non-woven. When the thickness ratio exceeds 1.00, the winding deviation or the paper tube offset is liable to occur, and the feel of the non-woven fabric is impaired by the winding. The thickness ratio is preferably from 0.80 to 1.00, more preferably from 〇 85 to 0 96, in terms of maintaining the hand. The width of the roll of the nonwoven fabric roll of the present invention is not particularly limited, and the roll width is preferably 60 mm or more in terms of winding stability.

Regarding the diameter of the roll of the nonwoven fabric roll of the present invention, it is preferable that the roll diameter is 3 cm or more from the meaning of the long roll. Namely, the reel hugs: a range of not more than 30 cm can be easily taken up even without considering the problem of the present invention. The diameter of the reel is preferably 5 cm or more, and more preferably 70 cm or more. In terms of coiling stability, it is preferably within a range of 150 cm. The nonwoven fabric roll of the present invention preferably has a roll sliding strength of at least 8.0 N, m or more indicating a degree of winding. More preferably, it is 1 〇. 〇 N.m or more, and particularly preferably 12 〇 N'm or more. If the sliding strength of the reel is less than 8.0 N.m, the paper tube is likely to be displaced or the paper tube is detached, and it is difficult to maintain a stable roll form. The reeling strength of the reel can be adjusted by the winding tension at the time of winding. However, for example, when the pressing roller is used in combination, the pressing pressure may be gradually decreased as the winding is started from the start of winding. As long as the feel of the non-woven fabric is maintained, the greater the sliding strength of the reel, the better, but it is preferably within 150 N.m, preferably within 100 N.m, as a standard for not over-winding. The winding deflection of the nonwoven web of the present invention is preferably 〇 8 mm. The winding offset refers to a state in which the non-woven fabric is wound with respect to the end surface of the reel when the non-woven fabric reel is formed. That is, the larger the distance of the winding offset, the more unstable the winding. The winding offset is preferably within 5 mm in terms of the stability of the processing step ten non-woven reel. The paper tube offset of the nonwoven web of the present invention is preferably 〇 8 mm. The term "paper tube offset" refers to a state in which the paper tube is unaligned with respect to the non-woven fabric roll I63669.doc 201250077 when the non-woven fabric roll is formed. That is, the greater the distance of the paper tube offset, the more unstable the winding. In terms of the stability of the nonwoven web in the processing step, the paper tube offset is preferably within 5 mm. The roll diameter difference of the nonwoven web of the present invention is preferably 〇 8 mm. The difference in the diameter of the roll indicates the difference in the unevenness of the surface of the nonwoven roll, and is the difference between the maximum diameter and the minimum diameter in the width direction. That is, the larger the roll diameter difference, the more unstable the winding. The roll diameter difference is preferably within 5 mm in terms of the stability of the nonwoven web in the processing step. The surface friction coefficient MIU of the nonwoven fabric forming the nonwoven web of the present invention is preferably from 0.050 to 0.400. If the surface friction coefficient MIU exceeds 〇 4〇〇, the reel is easily caught in the step, or the non-woven reel is easily wound up.

The surface friction coefficient MIU is more preferably from 〇1〇〇 to 〇35〇, and particularly preferably from 0.100 to 0.300. » For the non-woven fabric roll of the present invention, the deformation caused by the compression load is not generated during the operation after packing. A defect such as pleats or damage is preferably such that the protective sheet presses both end faces of the nonwoven fabric roll or the most end faces of the plurality of non-woven fabric rolls, and is packaged in a crucible. The plural arrangement means that the end faces of the non-woven fabric (4) are overlapped with the end faces in such a manner that the cores of the reels are overlapped, and the ones are often arranged in the same reel diameter. The term "most ends" refers to a plurality of rows of non-woven fabric rolls which are placed on the outer end faces of the rolls at both ends. When pure, the sheet can be protected from the most end faces. The protective sheet is not particularly limited. It can be thermoplastic such as polystyrene or polypropylene. 163669.doc 201250077 Du Shuyue a manufacturer can also be paper thick paper or cardboard. The size of the protective sheet is generally the same as the diameter of the roll of the non-woven roll. In the operation after the bale of the non-woven fabric reel, the reel is stacked longitudinally in terms of handling efficiency and the like. Therefore, when the diameter of the protective sheet at least the end surface of the roll of the lower surface is in the range of 1 mm of the diameter of the roll, the protection effect of the corner portion of the roll is large, so that it is preferable. Further, it is possible to prevent the packaging film from being broken, etc., and 5' is more preferably in the range of -1 〇 mm to +5 mm. The film to be used for the packaging is not particularly limited, and is preferably a polyolefin-based thermoplastic resin film such as polyethylene having moisture impermeable properties which is not easily affected by environmental changes such as temperature and humidity when the nonwoven fabric roll is stored. Further, the bundle of non-woven fabric rolls can be used for manual packaging or by an automatic strapping machine. In terms of the ease of fixing the nonwoven web, it is preferred to wrap the film in a shrinkable film. Further, since the reel is stacked vertically in the operation as described above, when the corner portion of the lower surface is wound more than the upper surface, the protection effect of the reel angle 4 is large, so good. The nonwoven fabric which forms the nonwoven fabric roll of the present invention is not particularly limited, and in particular, a nonwoven fabric having a good hand feel is effective for obtaining a nonwoven fabric roll which is stably wound up, and which is excellent in handleability after being packaged. As the non-woven fabric having a good hand feeling, for example, a non-woven fabric obtained by attaching a hydrophilizing agent to a non-woven fabric or a non-woven fabric containing a softening agent may be used. As a hydrophilizing agent attached to the nonwoven fabric, in consideration of safety to the human body and safety in the step, it is preferred to add a higher alcohol, a higher fatty acid, and the like to the nonionic system obtained by the epoxy epoch. Active agent, crop base 163669.doc 201250077 An anionic active agent such as a phosphate or an alkyl sulfate is used alone or a mixture thereof or the like is used. Further, the amount of the hydrophilizing agent to be attached varies depending on the desired properties. For example, as a sanitary material, it is usually in the range of 〇1 to 丨〇 with respect to the fiber, and more preferably 0 2 to 0.6 in terms of performance. Wt0 / 〇β As a method of applying a hydrophilizing agent, a diluted hydrophilizing agent can be usually used, and a conventional method such as a dipping method, a spray method, and a coating (same coater, gravure coater) can be used. As a drying method at this time, a known method using convection heat transfer, conduction heat transfer, and radiation heat transfer may be employed, and drying by hot air or infrared rays or drying by thermal contact may be used. Further, as the softening agent contained in the nonwoven fabric, for example, an ester compound is preferable, and an ester compound of a polyhydric alcohol of 3 to 6 yuan and a monocarboxylic acid is more preferably used. Examples of the 3 to 6-membered polyhydric alcohol include a trihydric alcohol such as glycerin or trimethylolpropane; and 4 quaternary tetraol, glucose, sorbitan, diglycerin, and ethylene glycol diglyceride; A polyhydric alcohol; a 5-valent polyhydric alcohol such as triglycerin or trimethylolpropane diglyceryl ether; a 6-membered polyhydric alcohol such as sorbitol, tetraglycerin or dipentaerythritol.

Oils derived from natural products can also be used. The ester compound containing an unsaturated fatty acid is easily oxidized, and is easily oxidized and deteriorated during melt spinning, and thus is preferably a saturated aliphatic monocarboxylic acid or an aromatic monocarboxylic acid. When a fat or oil derived from a natural product is used, it is odorless and stable in comparison with the raw material oil, and therefore it is preferred to use a hydrogenated ester compound. It is important for the ester compound that the molecular weight of the monocarboxylic acid is relatively large and the lipophilicity is high. In the case of a polyolefin-based fiber, since it is highly lipophilic, it enters into a non-BB.卩 inhibits crystallization and increases the amorphous region, so flexibility can be obtained. The content of the ester compound is preferably 〇 3 or more and 5 Å 〇 wt% or less based on the thermoplastic fiber. Even if a small amount is added to the ester compound, the flexibility of bending or the ease of sliding are remarkably improved, and even if the content is increased, the performance improvement in proportion to the content is not exhibited. Accordingly, the content of the ruthenium compound is suitably 5.0 wt% or less, more preferably 0 5 wt% to 3.5 wt%, and particularly preferably 0.5 wt% to 2 〇. /〇. The non-woven fabric roll of the present invention is excellent in handling and processing suitability because it can be wound up stably, and is particularly preferably used for sanitary materials such as disposable fabrics, menstrual sanitary napkins, and incontinence pads which require a hand.

The friction elements and specimens formed by bending 10 piano wires with a diameter of 0.5 mm into a U-shape are arranged under standard measurement conditions (sensitivity: Η, speed: 1 mm/sec, crimping pressure of the sample and the friction member: 5 〇 gf) T was rubbed and the MIU was measured. The longitudinal (MD) direction was measured 3 times and expressed as the average value. A smaller value indicates less frictional resistance. 3. Roll sliding strength (Nm) in the paper tube of the non-woven fabric roll, the insertion surface is a rubber-made roll sliding special fixed shaft (the rubber length is 5 cm in contact with the inner surface of the paper tube), and the shaft is filled with two gas. The fixed pressure is applied to make the inner side of the paper tube and the rubber close to each other. Then, using a torque wrench, the special fixed shaft for rolling the drum is rotated in the winding direction of the winding, and the strength of the measuring tube is rotated. That is, the so-called monthly luma strength ' indicates that the degree of tightness of the non-woven fabric on the paper tube 'the lower the monthly kinematic strength of the reel' means that the paper tube is displaced more easily and the paper tube is detached, and is extracted in the processing step.
