DETAILED DESCRIPTION OF THE INVENTION

[0009] Below, various embodiments of the resin sheet will be described, followed by a description of a method for manufacturing the resin sheet, but if a specific description given for one embodiment also applies to other embodiments, that description will be omitted in the other embodiments.

[0010] [First embodiment] The resin sheet according to the first embodiment of the present invention has a base layer having regularly arranged hairs on at least one surface thereof, and a fiber sheet layer on the surface of the base layer opposite the hairs, with no structural boundary between the base layer and the hairs forming a continuous phase. That is, the layer structure of the resin sheet according to this embodiment is, from top to bottom, hairs and the base layer (1), and a fiber sheet layer (2).

[0011] <Underlayer> The base layer (1a) is a layer underlying the hairs and refers to the portion of the reference numeral 1 other than the surface hairs 1b. The thickness of the base layer refers to the thickness from the base of the hairs to the surface opposite the base layer. The average thickness of the base layer is preferably 15 μm to 300 μm, more preferably 30 μm to 280 μm, and even more preferably 50 μm to 250 μm. A thickness of 15 μm or more allows the hairs to be sufficiently tall. Furthermore, a thickness of 300 μm or less not only allows the hairs to be formed efficiently but also reduces the weight of the resin sheet. There may be no structural boundary between the base layer and the hairs, forming a continuous phase. "Structurally, there is no structural boundary" means that the base layer and the hairs are formed integrally, with no clear structural boundary between them. "Forming a continuous phase" means that there is no seam between the base layer and the hairs, and they are not discontinuous (continuous phase). In this respect, it differs from a structure in which hairs are implanted on a base layer. The base layer and hairs may have the same composition, and the bond between the base layer and hairs may include a covalent bond. A covalent bond is a chemical bond formed by the sharing of an electron pair between two atoms. In thermoplastic resins, which are chain molecules made up of linked monomers, the individual polymers are bonded by covalent bonds, which are stronger than the van der Waals bonds or hydrogen bonds that act between polymer molecules. The base layer and the hairs may be derived from the same solid thermoplastic resin sheet, which is not separate. Derived from the same solid thermoplastic resin sheet means, for example, that the hairs and the base layer are obtained directly or indirectly from the same resin sheet. The base layer and the hairs may be formed from the same solid thermoplastic resin sheet, which means that the hairs and the base layer are directly formed by processing a single resin sheet. The absence of a structural boundary between the base layer and the hairs forms a continuous phase, preventing the hairs from separating from the base layer due to external stimuli, resulting in a sheet with a good feel to the touch. Furthermore, the sheet can be manufactured with fewer steps than when the hairs are implanted.

[0012] The base layer and the hair-like bodies are made of the same thermoplastic resin composition, with a thermoplastic resin as the main component. Here, "mainly composed" means that the thermoplastic resin is contained in an amount of 50% by mass or more. Preferably, the amount is 60% by mass or more, 70% by mass or more, 80% by mass or more, or 90% by mass or more. In one embodiment of the present invention, a resin containing at least one of thermoplastic polyurethane resin (TPU), styrene-based resin, polyolefin-based resin, polyvinyl chloride resin, thermoplastic elastomer, and fluorine-based resin can be used.

[0013] Thermoplastic polyurethane resin is a resin made from the reaction raw materials of diisocyanate and polyol. The combination of diisocyanate is diphenylmethane diisocyanate (MDI), H 12 Any combination of MDI-based or hexamethylene diisocyanate (HDI)-based polyol and polyether-based, polyester-based, or polycarbonate-based polyol may be selected, or a combination of two or more thereof may be used. In one embodiment of the present invention, a combination of an MDI-based or HDI-based diisocyanate and a carbonate-based polyol is preferably used.

[0014] Examples of styrene-based resins that can be used include homopolymers or copolymers of styrene-based monomers such as styrene, α-methylstyrene, p-methylstyrene, dimethylstyrene, pt-butylstyrene, and chlorostyrene; copolymers of these styrene-based monomers with other monomers, such as styrene-acrylonitrile copolymers (AS resins); and graft polymers obtained by graft polymerization of the styrene-based monomers with other polymers, such as diene rubber polymers such as polybutadiene, styrene-butadiene copolymers, polyisoprene, and polychloroprene, such as high-impact polystyrene (HIPS resins) and styrene-acrylonitrile graft polymers (ABS resins). Styrene-based thermoplastic elastomers can also be used.

[0015] Polyolefin resins refer to resins made of polymers containing α-olefins as monomers, and include polyethylene resins and polypropylene resins. Examples of polyethylene resins include high-density polyethylene, low-density polyethylene, linear low-density polyethylene, and linear medium-density polyethylene. Not only simple polyethylenes but also copolymers, graft compounds, and blends having these structures can be used. Examples of the latter resins include copolymers and blends of resins having polar groups in the polyethylene chain, such as ethylene-vinyl acetate copolymers, ethylene-acrylic acid copolymers, ethylene-acrylic acid ester copolymers, ethylene-methacrylic acid ester copolymers, ethylene-vinyl acetate-vinyl chloride copolymers, and terpolymers with acid anhydrides.

[0016] Furthermore, examples of polypropylene resins that can be used include homopolypropylene, random polypropylene, and block polypropylene. When homopolypropylene is used, the structure of the homopolypropylene may be isotactic, atactic, or syndiotactic. When random polypropylene is used, the α-olefin copolymerized with propylene preferably has 2 to 20 carbon atoms, more preferably 4 to 12 carbon atoms, such as ethylene, 1-butene, 1-pentene, 1-hexene, 1-heptene, 1-octene, 1-nonene, and 1-decene. When block polypropylene is used, a block copolymer (block polypropylene), a block copolymer containing a rubber component, or a graft copolymer can be used. These olefin resins can be used alone or in combination with other olefin-based resins.

[0017] The polyvinyl chloride resin can be a vinyl chloride homopolymer or a copolymer of vinyl chloride and other comonomers. When polyvinyl chloride is a copolymer, it can be a random copolymer or a graft copolymer. Examples of graft copolymers include those in which vinyl chloride is graft-polymerized onto an ethylene-vinyl acetate copolymer or a thermoplastic urethane polymer as a backbone polymer. The polyvinyl chloride of this embodiment is an extrusion-moldable flexible polyvinyl chloride composition containing additives such as a polymeric plasticizer. Known polymeric plasticizers can be used, but preferred examples include ethylene copolymer polymeric plasticizers such as ethylene-vinyl acetate-carbon monoxide copolymer, ethylene-(meth)acrylate-carbon monoxide copolymer, and ethylene-vinyl acetate copolymer with a high vinyl acetate content.

[0018] Thermoplastic elastomers include those having a structure combining a soft polymeric substance and a hard polymeric substance. Specific examples include styrene-based elastomers, olefin-based elastomers, vinyl chloride-based elastomers, polyester-based elastomers, and polyamide-based elastomers. These elastomers can be selected from commercially available products.

[0019] Examples of fluorine-based resins that can be used include vinylidene fluoride homopolymers and vinylidene fluoride copolymers containing vinylidene fluoride as a main component. Polyvinylidene fluoride (PVDF) resins are crystalline resins that exhibit various crystal structures, such as α-type, β-type, γ-type, and αp-type. Examples of vinylidene fluoride copolymers include vinylidene fluoride-hexafluoropropylene copolymers, vinylidene fluoride-tetrafluoroethylene copolymers, vinylidene fluoride-chlorotrifluoroethylene copolymers, vinylidene fluoride-trifluoroethylene copolymers, vinylidene fluoride-tetrafluoroethylene-hexafluoropropylene terpolymers, vinylidene fluoride-chlorotrifluoroethylene-hexafluoropropylene terpolymers, and mixtures of two or more of these.

[0020] The melt mass flow rate of the thermoplastic resin composition at 190°C to 300°C is preferably 4 g / 10 min or more. By making it 4 g / 10 min or more, the transferability of the shape of the capillaries can be improved. The melt mass flow rate is a value measured according to JIS K 7210 at a test temperature range of 190°C to 300°C under a load of 2.16 kg to 10.0 kg.

[0021] The thermoplastic resin composition may be an alloy of the above-mentioned thermoplastic resins in any ratio, provided that the effects of the present invention are not impaired. Furthermore, other additives may be added. Examples of other additives that may be added, provided that the effects of the present invention are not impaired, include water / oil repellents, colorants such as pigments and dyes, lubricants / release agents such as silicone oils and alkyl esters, fibrous reinforcing agents such as glass fiber, fillers such as granular fine particles such as talc, clay, and silica, and scaly fine particles such as mica, low-molecular-weight antistatic agents such as salt compounds of sulfonic acid and alkali metals, high-molecular-weight antistatic agents such as polyether ester amides, and additives such as flame retardants, antibacterial agents, antiviral agents, and heat stabilizers. Scrap resin generated during the resin sheet manufacturing process may also be added.

[0022] Examples of water- and oil-repellents include silicone-based water- and oil-repellents, carnauba wax, and fluorine-based water- and oil-repellents. Examples of silicones include organopolysiloxane, dimethylpolysiloxane, methylphenylpolysiloxane, and methylhydrogenpolysiloxane, with dimethylpolysiloxane being particularly preferred. Commercially available products include silicone-based resin alloys such as "Clinbell CB50-PP," "Clinbell CB-30PE," "Clinbell CB-1," and "Clinbell CB-50AB" (manufactured by Fuji Chemical Co., Ltd.). Commercially available carnauba waxes include "Carnauba No. 1" (manufactured by Nikko Rica Corporation). Fluorine-based water- and oil-repellents include surfactants with perfluoroalkyl groups, such as "Surflon KT-PA" (manufactured by AGC Seimi Chemical Co., Ltd.). The amount of water- and oil-repellent added is preferably 0.5% to 25% by mass. If the content is less than 0.5% by mass, there is a risk that sufficient water and oil repellency may not be obtained, and if the content exceeds 25% by mass, there is a risk that moldability may deteriorate.

[0023] Examples of antistatic agents include polyetheresteramide-based polymeric antistatic agents and ionomer-based polymeric antistatic agents. Commercially available polyetheresteramide-based polymeric antistatic agents include "Pelestat 230," "Pelestat 6500," "Pelectron AS," and "Pelectron HS" (manufactured by Sanyo Chemical Industries, Ltd.). Commercially available ionomer-based polymeric antistatic agents include "Entira SD100" and "Entira MK400" (manufactured by DuPont-Mitsui Polychemicals). The amount of antistatic agent added is preferably 5% to 30% by mass. If the amount is less than 5% by mass, sufficient antistatic properties may not be obtained, and if the amount is more than 30% by mass, production costs increase.

[0024] The antibacterial agent may be either inorganic or organic. In terms of dispersibility, inorganic agents are preferred. Specific examples include inorganic antibacterial agents based on metal ions (Ag, Zn, Cu) and calcined shell calcium antibacterial agents. Commercially available inorganic antibacterial agents based on metal ions include "Bactekiller BM102VT" (manufactured by Fuji Chemical Co., Ltd.), "Novalon VZF200," "Novalon (AG300)" (manufactured by Toagosei Co., Ltd.), "KM-10D-G," and "IM-10D-L" (manufactured by Sinanen Zeomic Co., Ltd.). Examples of calcined shell calcium antibacterial agents include "Scallow" (manufactured by FID). The amount of antibacterial agent added is preferably 0.5% to 5% by mass. Less than 0.5% by mass may result in insufficient antibacterial activity, while more than 5% by mass increases production costs.

[0025] Examples of lubricants and release agents that can be used include alkyl-based lubricants and release agents such as aliphatic hydrocarbon compounds, higher fatty acid compounds, higher aliphatic alcohol compounds, and fatty acid amide compounds, as well as silicone-based lubricants and release agents and fluorine-based lubricants and release agents. When using a lubricant or release agent, the amount added is preferably 0.01 to 5 parts by mass, more preferably 0.05 to 3 parts by mass, and even more preferably 0.1 to 2 parts by mass, out of a total of 100 parts by mass of the resin composition. Adding an amount of 0.01 parts by mass or more reduces the risk of reduced release effectiveness, while adding an amount of 5 parts by mass or less reduces the risk of bleeding out onto the sheet surface.

[0026] Masterbatches in which lubricants and release agents are pre-alloyed with thermoplastic resins can also be used. For example, "Wax Master V" (manufactured by BASF) is a commercially available masterbatch based on a urethane-based thermoplastic elastomer, and in terms of production efficiency, it is preferable to use a masterbatch. The amount of masterbatch added is preferably 1 to 8 parts by mass, more preferably 2 to 7 parts by mass, and even more preferably 3 to 6 parts by mass, out of a total of 100 parts by mass including the resin composition.

[0027] <hairy body> The hairs (1b) refer to the hair-like portions extending from the surface of the base layer (1a) as shown in FIG. 1. The hairs are regularly arranged on the surface of the base layer. Regularly arranged here means that the hairs are not randomly arranged, i.e., arranged in an orderly manner (e.g., at regular intervals) in one or two directions. The regularity of the arrangement of the hairs is determined by the arrangement of the hair roots. In one embodiment, the hairs are positioned on the base layer at regular intervals, and the positions of the bases of the hairs are regularly arranged in the longitudinal and lateral directions of the base layer. The arrangement of the hairs is not particularly limited, and may be arranged in a checkerboard pattern or a staggered pattern. Regularly arranging the hairs on the surface of the base layer facilitates the development of a uniform, consistent, and pleasant tactile feel. When a load is applied, such as by tracing the hairs with a finger, the hairs may collapse, forming a finger mark that appears to have a different luster and color tone from the surrounding area. The hairy material can also provide a suede-like feel to the touch.

[0028] The average height (h) of the hairs is preferably 30 μm to 500 μm, more preferably 60 μm to 250 μm, even more preferably 80 μm to 200 μm, and even more preferably 90 μm to 180 μm. By setting the average height to 30 μm or more, a good tactile sensation can be sufficiently ensured, and by setting the average height to 500 μm or less, good tactile sensations such as a moist feel, a soft feel, and a fluffy feel can be obtained. When the hairs are almost upright relative to the base layer, the length from the base to the tip represents the height of the hairs. On the other hand, when the hairs are inclined relative to the base layer or have a wound portion, the height h of the hairs is the distance from the surface of the base layer to the point where the hairs are furthest from the surface of the base layer. In addition, the total value of the intervals subdivided by multi-point measurement from the tip to the center of the base of the hair is the length L of the hairs. The average height and length of the hairs can be determined by measuring the height and length of the hairs at any number of locations on the resin sheet using an electron microscope and image processing software, and then calculating the arithmetic mean value of the measured values.

[0029] The average diameter (d) of the hairs is preferably 1 μm to 50 μm, more preferably 5 μm to 50 μm, and even more preferably 5 μm to 40 μm. By setting the average diameter of the hairs to 1 μm or more, a good tactile sensation can be ensured, while by setting the average diameter of the hairs to 50 μm or less, good tactile sensations such as a moist, soft, and fluffy feel can be obtained. The average diameter of the hairs is determined by measuring the diameter at the mid-height (h / 2) of the hairs from several points on the resin sheet using an electron microscope and image processing software, and then calculating the arithmetic mean value of the measured values. The aspect ratio of the hairs can be expressed as (average height of hairs / average diameter of hairs). The aspect ratio of the hairs is preferably 2 to 20, more preferably 2 to 10, and even more preferably 2 to 5. An aspect ratio of 2 or more ensures a good tactile sensation, while an aspect ratio of 20 or less not only provides good tactile sensations such as a moist, soft, and fluffy feel, but also reduces the risk of the ratio of height to length of the hairs falling below a certain level. On the other hand, the aspect ratio can also be determined based on the average basal diameter of the hairs. The average basal diameter of the hairs is preferably 10 μm to 150 μm, more preferably 20 μm to 120 μm, and even more preferably 30 μm to 100 μm. The average basal diameter of the hairs is determined by measuring the distance between adjacent hairs at several locations on the resin sheet and calculating the arithmetic mean value of the measured values. When the basal diameter of the hairs is used as the basis, the aspect ratio is preferably 1.0 to 10, more preferably 1.0 to 5, and even more preferably 1.0 to 2.5. By setting the aspect ratio to 1.0 or more, a good tactile sensation can be ensured. By setting the aspect ratio to 10 or less, not only can good tactile sensations such as a moist feel, a soft feel, and a fluffy feel be obtained, but also the risk of the ratio of height to length of the hairs falling below a certain level can be reduced.

[0030] The average spacing (t) of the hairs is preferably 20 μm to 200 μm, more preferably 40 μm to 150 μm, and even more preferably 40 μm to 100 μm. The spacing of the hairs refers to the distance between the center of the base of a hair and the center of the base of an adjacent hair, as shown in FIG. 2, for example. By setting the average spacing to 20 μm or more, a good tactile sensation is ensured, while by setting it to 200 μm or less, good tactile sensations such as a moist, soft, and fluffy feel are obtained. The average spacing of the hairs is determined by measuring the spacing between adjacent hairs at several points on the resin sheet and calculating the arithmetic mean value of the measured values.

[0031] The shape of the hairs is not particularly limited, but may be such that they extend in a hair-like manner in the direction away from the base layer and gradually become thinner as they approach the tip, or may have a bulge at the tip. In other words, the cross-sectional area may gradually decrease with increasing distance from the base layer, then increase once and terminate. The tip of the hair may be bud-shaped or mushroom-shaped. The hair may have a base-end portion extending away from the base layer, a portion extending from the base-end portion and bending with a constant curvature or a gradually changing curvature, or even a spiral or spiral-shaped portion. In this case, the tip of the hair may be folded inward. Such a shape provides a good tactile sensation. Furthermore, the bud-shaped or mushroom-shaped portion being hollow provides a more favorable tactile sensation. When bud- or mushroom-shaped hair tips are formed, the ratio of the average diameter of the bud- or mushroom-shaped hairs to the average diameter of the width of the bud- or mushroom-shaped hairs is preferably 1.1 or more. The height of the bud- or mushroom-shaped hairs is preferably 7 μm or more. The average diameter of the hairs, the average diameter of the width of the bud- or mushroom-shaped hairs, and the height are measured using electron scanning microscope photographs, and the arithmetic mean values ​​are used. The hairs are made of a thermoplastic resin. The thermoplastic resin may be the same as the resin that can be used in the base layer.

[0032] The thermoplastic resin contained in the base layer and hairs may at least partially form a three-dimensional crosslinked structure (e.g., a three-dimensional network structure). For example, in one embodiment, at least a portion of the hairs may be crosslinked; in another embodiment, the entire surface of the hairs may be crosslinked; and in yet another embodiment, the entire hairs (from the boundary with the base layer to the tip) may be crosslinked. Methods for forming the crosslinked body include, for example, a method in which a resin sheet is molded and then the surface having the hairs is irradiated with an electron beam, and a method in which an organic peroxide is added and then heated and humidified during or after molding of the resin sheet. Commercially available resins containing added organic peroxide include "Linkron" manufactured by Mitsubishi Chemical Corporation. In this embodiment, it is preferable to form a crosslinked body (electron beam crosslinked body) by irradiating with an electron beam.

[0033] <Fiber sheet layer> The fibrous sheet layer (2) is a layer that is laminated directly or indirectly on the surface of the base layer opposite to the hair-like bodies, and includes a sheet of fibrous structures. The thickness of the fibrous sheet layer is preferably 100 μm to 3000 μm, more preferably 200 μm to 2500 μm, and even more preferably 300 μm to 2000 μm. By making the thickness 100 μm or more, it is possible to feel compressibility when touched. Furthermore, by making the thickness 3000 μm or less, it is possible to reduce manufacturing costs. The thickness of the fibrous sheet layer can be measured in accordance with JIS L 1913:2010.

[0034] The average fiber diameter of the fibrous structures contained in the fiber sheet layer is preferably 0.1 μm to 150 μm, more preferably 0.5 μm to 100 μm, and even more preferably 1.0 μm to 80 μm. By setting the diameter to 0.1 μm or more, costs can be reduced. Furthermore, by setting the diameter to 150 μm or less, smoothness can be felt when touched. In another embodiment, the average fiber diameter of the fibrous structures contained in the fiber sheet layer is preferably 0.1 μm to 80 μm, more preferably 0.5 μm to 50 μm, and even more preferably 1.0 μm to 30 μm. By making it 0.1 μm or more, costs can be reduced. Furthermore, by making it 80 μm or less, it is possible to achieve a smooth feel when touched. The average fiber diameter can be determined by measuring the fiber diameter at any number of points of the fibrous structure using an electron microscope and image processing software, and then calculating the arithmetic mean value of the measured values.

[0035] The fiber sheet layer has a basis weight of 10 g / m 2 More than 400g / m 2 It is preferable that the thickness is less than 50 g / m 2 More than 200g / m 2 It is more preferable that the basis weight is 10 g / m or less. The basis weight can be measured in accordance with JIS L 1913:2010 or JIS L 1096:2010. 2 By setting the weight to 400g / m or more, the fabric can be transported without breakage during roll-to-roll processing. 2 The weight of the resin sheet can be reduced by the following: The basis weight can be adjusted by the material, diameter, and manufacturing method of the fiber.

[0036] The raw material of the fibrous structure forming the fiber sheet layer is not particularly limited, and examples thereof include chemical fibers and natural fibers. Examples of chemical fibers include chemical fibers containing at least one of polyester-based resins, polyethylene-based resins, polypropylene-based resins, polystyrene-based resins, polyamide-based resins, polyvinyl alcohol-based resins, and polyacrylonitrile-based resins. As with the thermoplastic resin composition forming the base layer and the hair-like bodies, other additives may be contained within a range that does not impair the effects of the present invention. Other chemical fibers include recycled fibers primarily composed of cellulose or protein, and inorganic fibers such as carbon fiber and glass fiber. Examples of natural fibers include plant fibers such as cotton and hemp, and animal fibers such as wool and silk. The structure of the fiber sheet layer may be nonwoven fabric, woven fabric, knitted fabric, or the like. A nonwoven fabric refers to a fabric in which fibers are unidirectionally or randomly oriented and bonded by entanglement, fusion, and / or adhesion. In one embodiment of the present invention, the nonwoven fabric preferably does not include paper, woven fabric, knitted fabric, tufted fabric, or crepe felt. Depending on the manufacturing method, nonwoven fabrics include chemically bonded nonwoven fabrics, thermally bonded nonwoven fabrics, needle-punched nonwoven fabrics, spunlaced nonwoven fabrics, spunbonded nonwoven fabrics, melt-blown nonwoven fabrics, and the like, and any of these can be appropriately selected and used. Woven fabrics are fabrics in which warp and weft threads are interwoven (by a loom), usually at right angles to each other. Depending on the weaving method, woven fabrics can be plain weave, twill weave, satin weave, etc., and can be selected appropriately. Knitted fabrics refer to fabrics made by joining loops of one or more knitting yarns to form continuous new loops. Depending on the knitting method, there are woven fabrics knitted by weft knitting machines such as circular knitting machines, and warp knitting machines such as tricot knitting machines, Russell knitting machines, and Milanese knitting machines, and any suitable knitting method can be selected and used.

[0037] <Resin sheet> In this embodiment, "tactile sensation" refers to the texture and feel of the surface of the resin sheet. It is determined whether the surface of the resin sheet feels comfortable to the touch, and if so, a good tactile sensation is defined as a specific pleasant feel, such as moist, soft, or fluffy.

[0038] In one embodiment of the present invention, the thickness of the resin sheet refers to the combined thickness of the average height of the hairs, the average thickness of the base layer, and the average thickness of the fiber sheet layer. The thickness of the resin sheet is preferably 95 μm to 2500 μm, more preferably 190 μm to 1900 μm, and even more preferably 280 μm to 1500 μm. A thickness of 95 μm or more ensures a satisfactory tactile feel, while a thickness of 2500 μm or less reduces manufacturing costs. The thickness of the resin sheet can be measured in accordance with JIS L 1913:2010.

[0039] In one embodiment of the present invention, the resin sheet preferably has a bending resistance measured in accordance with the 45 cantilever method of JIS L 1096:2010 of 150 mm or less, more preferably 140 mm or less, and even more preferably 130 mm or less. Good processability can be achieved by setting the bending resistance measured in accordance with the 45 cantilever method of JIS L 1096:2010 to 150 mm or less. A certain bending resistance can be achieved by adjusting the type of resin used when synthesizing the thermoplastic resin composition, the type of fibrous structure (material, fiber diameter, basis weight), and the like.

[0040] In one embodiment of the present invention, the resin sheet has a compression work capacity of 0.02 gf cm / cm as measured by the KES method. 2 More than 0.20gf cm / cm 2 It is preferable that it is less than 0.02 gf cm / cm 2 More than 0.18gf cm / cm 2 It is more preferable that it is less than 0.02 gf cm / cm 2 More than 0.16gf cm / cm 2 It is even more preferable that: The compression work load is measured by first placing a 200mm x 200mm resin sheet as a sample in a compression tester with the side with the hairs facing upward, and compressing the center of the resin sheet from the side with the hairs. 2 Maximum compression load with a circular plate: 10gf / cm 2 The compression is performed at a compression speed of 20 μm / sec. As the compression tester, for example, KES-FB3-A manufactured by Kato Tech Co., Ltd. can be used. The compression work measured by the KES method is 0.02 gf·cm / cm 2 A good texture can be achieved by setting the compression work load measured by the KES method to 0.20 gf cm / cm or more. 2 The following can improve handling during sewing. A certain compression work load can be achieved by adjusting the type of resin used when synthesizing the thermoplastic resin composition, the type of fibrous structure (material, fiber diameter, basis weight), and the like.

[0041] The resin sheet according to one embodiment of the present invention has a basis weight of 100 g / m 2 More than 450g / m 2 It is preferable that the thickness is less than 125 g / m 2 More than 435g / m 2 It is more preferable that it is 150 g / m or less. 2 More than 420g / m 2 It is more preferable that the basis weight is as follows: The basis weight of each resin sheet can be measured in accordance with JIS P8124 (2011) "Paper and paperboard - Method for measuring basis weight". Basis weight: 100g / m 2 By setting the basis weight at 450 g / m or more, deformation and breakage of the resin sheet can be suppressed. 2 By doing so, the weight of the sewn product can be reduced. A certain basis weight can be achieved by adjusting the type of resin used when synthesizing the thermoplastic resin composition, the type of fibrous structure (material, fiber diameter, basis weight), and the like.

[0042] The resin sheet according to one embodiment of the present invention preferably has a tensile strength of 1 MPa or more and 25 MPa or less, more preferably 1 MPa or more and 10 MPa or less, and even more preferably 1 MPa or more and 5 MPa or less. The tensile strength of each resin sheet can be measured according to JIS K 7161. A tensile strength of 1 MPa or more allows the material to be transported without breakage during roll-to-roll processing, while a tensile strength of 25 MPa or less prevents burrs and cracks from occurring during sewing. A certain level of tensile strength can be achieved by adjusting the type of resin used when synthesizing the thermoplastic resin composition, the type of fibrous structure (material, fiber diameter, basis weight), and the like.

[0043] The resin sheet according to one embodiment of the present invention preferably has a tear strength of 1 N / mm to 30 N / mm, more preferably 5 N / mm to 30 N / mm, and even more preferably 10 N / mm to 30 N / mm. The tear strength of each resin sheet can be measured according to JIS K 7128-3. A tear strength of 1N / mm or more allows the material to be transported without breakage during roll-to-roll processing, while a tear strength of 30N / mm or less prevents burrs and cracks from occurring during sewing. A certain level of tear strength can be achieved by adjusting the type of resin used when synthesizing the thermoplastic resin composition, the type of fibrous structure (material, fiber diameter, basis weight), and the like.

[0044] [Second embodiment] An example of the resin sheet according to the second embodiment of the present invention is a resin sheet in which a base layer is formed on the surface of the fiber sheet layer opposite to the base layer side, as shown in Fig. 3. That is, the layer structure of the resin sheet according to the second embodiment is, from top to bottom, hair-like bodies and base layer (1), fiber sheet layer (2), and base layer (3). Here, the hairs and the base layer are the same as those described in the first embodiment, so a description thereof will be omitted. The total average thickness of the hairs, the base layer, the fiber sheet layer, and the base layer is 95 μm to 2500 μm, more preferably 190 μm to 1900 μm, and even more preferably 280 μm to 1500 μm. The average thickness of the base material layer is preferably 15 μm to 100 μm, more preferably 15 μm to 50 μm. By setting the average thickness of the base material layer to 100 μm or less, losses in sewing processability, cushioning properties, and lightweight feel of the resin sheet can be suppressed. The base layer of the resin sheet according to the second embodiment preferably uses a thermoplastic resin that can adhere to the fiber sheet layer. For example, the same thermoplastic resin composition as that of the underlayer, polycarbonate-based resin, polyester-based resin, or a polymer alloy resin thereof can be suitably used. The mass ratio of the polycarbonate-based resin to the polyester-based resin is preferably 50:50 to 90:10, more preferably 60:40 to 80:20, and even more preferably 65:35 to 75:25. Here, the polymer alloy resin refers to a polymer multi-component system, and may be a polymer blend having a certain degree of compatibility due to mixing, a block copolymer or graft copolymer obtained by copolymerization, or a mixture of resins that are not compatible with each other. Examples of polycarbonate resins include those derived from aliphatic dihydroxy compounds and those derived from aromatic dihydroxy compounds. For example, those derived from aromatic dihydroxy compounds can be suitably used, and particularly those derived from aromatic dihydroxy compounds (bisphenols) in which two aromatic dihydroxy compounds are bonded via a certain type of bonding group are preferred. These can be produced by a known method of polycondensation of a dihydroxy compound with phosgene or a carbonate ester, but are not limited to this production method, and commercially available resins can also be used. Examples of polyester-based resins that can be used include polyethylene terephthalate, polybutylene terephthalate, polyethylene-2,6-naphthalate, polymethylene terephthalate, and polyester resins copolymerized with copolymer components such as diol components, such as diethylene glycol, neopentyl glycol, and polyalkylene glycol, and dicarboxylic acid components, such as adipic acid, sebacic acid, phthalic acid, isophthalic acid, and 2,6-naphthalenedicarboxylic acid. The substrate layer may contain other additives as needed. These additives include water repellents, oil repellents, colorants such as pigments and dyes, lubricants and release agents such as silicone oils and alkyl esters, fibrous reinforcing agents such as glass fiber, fillers such as granular fine particles such as talc, clay, and silica, and scaly fine particles such as mica, low-molecular-weight antistatic agents such as salt compounds of sulfonic acid and alkali metals, high-molecular-weight antistatic agents such as polyether ester amides, and additives such as flame retardants, antibacterial agents, antiviral agents, and heat stabilizers, provided that the additives do not impair the effects of the present invention. Scrap resin generated during the resin sheet manufacturing process may also be mixed and used. Furthermore, the substrate layer may have a partially crosslinked structure, provided that the additives do not impair the effects of the present invention.

[0045] [Manufacturing of resin sheets] The method for producing a resin sheet according to the present invention is not limited and may be any method, but typically includes the steps of melt-extruding a raw resin, laminating the resulting resin sheet with a fiber sheet, and providing regularly arranged hair-like bodies on at least one surface of the resin sheet. For example, a feed block or a multi-manifold die can be used during production. The layer structure of each embodiment of the resin sheet of the present invention is basically as described above. In addition, for example, scrap raw material generated during the production process of the resin sheet or molded container of the present invention may be added to the substrate layer or laminated as an additional layer, as long as no deterioration in physical properties is observed.

[0046] The method for providing the hairy bodies is not particularly limited, and any method known to those skilled in the art can be used, such as a manufacturing method using an extrusion molding method, a manufacturing method using a roll-to-roll method, a manufacturing method using a photolithography method, a manufacturing method using a heat press method, a manufacturing method using a pattern roll and a UV-curable resin, a manufacturing method using a 3D printer, or a method in which the hairy bodies are embedded in a resin layer and then covalently bonded by a polymerization reaction.

[0047] For example, when using an extrusion molding method, a resin sheet according to the present invention can be produced by extruding a resin sheet using a T-die method, and casting the resin sheet with a transfer roll having an uneven surface and a touch roll so as to impart a hair-like shape to the surface of the resin sheet. As the transfer roll having the textured surface, a roll having fine textures of several μm to several hundred μm in size regularly formed on its surface by laser engraving, electroforming, etching, mill engraving, or the like can be used. Here, "regular" means that the textures are not randomly arranged, i.e., arranged in an orderly manner in one or two directions. In some embodiments, the textures can be arranged in a grid pattern or a staggered pattern, with the textures arranged lengthwise and widthwise. Examples of the shape of the textured portion include, for example, a cone (e.g., a cone, a square pyramid, a triangular pyramid, a hexagonal pyramid), a semicircle, or a rectangle (a square prism). The size of the recesses ranges from several μm to several hundred μm, with the opening diameter, depth, and spacing of the recesses. Examples of materials that can be used for the transfer roll include metals and ceramics. The spacing of the hairs can be adjusted by adjusting the spacing of the recesses on the transfer roll, and the height of the hairs can be adjusted by adjusting the depth of the recesses on the transfer roll, thereby adjusting the tactile feel. It is also preferable to process the transfer roll surface into unevenness with a high aspect ratio. For example, when processing recessed shapes on the transfer roll surface, the aspect ratio (recess depth / recess opening diameter) is preferably 1.0 to 9.0 or 1.0 to 2.0. To process the transfer roll surface into unevenness with a high aspect ratio, laser engraving or electroforming is particularly preferred because it is more suitable for precise processing in the depth direction than etching, blasting, mill engraving, etc. The transfer roll may be made of a material such as metal or ceramic. The touch roll may be made of a variety of materials, including silicone rubber, NBR rubber, EPT rubber, butyl rubber, chloroprene rubber, and fluororubber. In one embodiment, a touch roll having a rubber hardness (JIS K 6253) of 40 to 100 may be used. A Teflon (registered trademark) layer may be formed on the surface of the touch roll. The touch roll can be made of various materials, including, for example, silicone rubber, NBR rubber, EPT rubber, butyl rubber, chloroprene rubber, and fluororubber. In one embodiment, a touch roll having a rubber hardness (JIS K 6253) of 40 to 100 can be used. A Teflon (registered trademark) layer may be formed on the surface of the touch roll. The resin sheet of this embodiment can be produced by using the roll set of the transfer roll and the touch roll. In one embodiment, the temperature of the transfer roll is adjusted to a temperature near the crystalline melting temperature, glass transition point, or melting point of the thermoplastic resin (for example, 100 to 150°C when random polypropylene is used), and the pinch pressure between the transfer roll and the touch roll is adjusted to 30 to 120 kg / cm. 2 The resin sheet of this embodiment can be manufactured by casting the resin sheet as follows: The cast resin sheet is taken up at a line speed of 0.5 to 30 m / min using a pinch roll or the like. Although the above embodiments are specifically shown, the present invention is not limited to these.

[0048] The resin sheet having the hair-like bodies on its surface according to the present invention can be used in applications requiring the above-mentioned good tactile sensation. For example, the resin sheet of the present invention can be used in processed products such as clothing, fashion accessories, and daily necessities, preferably sewn products.

[0049] [Processed products] The processed product of the present invention is a processed product using the resin sheet of the present invention. The resin sheet of the present invention can be subjected to general sewing and pasting processes. Sewing processes include hand sewing, machine sewing, etc., but are not limited to these. Examples of clothing include coats, jackets, suits, sweaters, sweatshirts, shirts, pants, skirts, dresses, T-shirts, underwear, stockings, etc. Examples of decorative items include neckties, socks, gloves, hats, belts, bags, wallets, shoes, watch bands, and business card cases. Examples of everyday items include book covers and document cases. [Example]

[0050] The present invention will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited to the contents of the examples. In the examples, "parts" are by weight.

[0051] The various raw materials used in the examples and the methods for producing them are as follows. (1) Hairy body and underlayer (A-1) TPU (thermoplastic polyurethane resin) "ET880-10" (manufactured by BASF) (A-2) TPU (thermoplastic polyurethane resin) "P380POTA" (manufactured by Tosoh Corporation) (A-3) Release agent masterbatch "Wax Master V" (manufactured by BASF) (2) Fiber sheet layer (B-1) "ICG-103" (manufactured by Japan Vilene Co., Ltd.) Average fiber diameter: 14 μm, basis weight: 100 g / m 2 (B-2) "DS-90HP" (manufactured by Japan Vilene Co., Ltd.) Average fiber diameter: 18 μm, basis weight: 142 g / m 2 (B-3) "DS-45HP" (manufactured by Japan Vilene Co., Ltd.) Average fiber diameter: 18 μm, basis weight: 85 g / m 2 (3) Base material layer (C) PC / Polyester "PCX-6694" (manufactured by Sumika Polycarbonate Co., Ltd.)

[0052] The methods for evaluating various properties of the resin sheets produced in the examples and comparative examples and the sewn products made of the resin sheets are as follows.

[0053] (1) Average height of hairs, average diameter of hairs, average spacing of hairs, average thickness of base layer and substrate layer The height (h), diameter (d), spacing (t), and thickness of the base layer and substrate layer of the resin sheet were measured using a laser microscope (VK-X100, Keyence Corporation). The samples measured were cross-sectional slices cut from three arbitrary locations on the resin sheet using a microtome. The average height of the hairs was determined by measuring the height of 10 hairs for each sample, and the arithmetic mean value of 30 measurements was used. The average diameter of the hairs was determined by measuring the diameter of 10 hairs at the mid-height (h / 2) for each sample, and the arithmetic mean value of 30 measurements was used. The average spacing of the hairs was determined by measuring the distance between the center of the base of a hair and the center of the base of an adjacent hair at 10 locations for each sample, and the arithmetic mean value of 30 measurements was used. The average thickness of the base layer and substrate layer was determined by measuring the thickness of each layer at 10 locations for each sample, and the arithmetic mean value of 30 measurements was used. The thickness of the base layer is the distance from the base of the hair to the interface with the other layer.

[0054] (2) Sensory evaluation of good tactile sensation For the good tactile feel, a sensory evaluation was conducted in which a total of 10 external panelists, five men and five women, touched the resin sheets. The specific tactile feel (smooth, silky, moist, dry, rough, etc.) when touching the surface of the resin sheet was evaluated on a scale of 1 to 10, and the feel with the highest score was designated as the tactile feel of the resin sheet surface. In Table 1, "◯" indicates that the score for smooth, silky, or moist was high, and a good tactile feel like a suede-like brushed sheet was obtained even after processing. "X" indicates that the score for dry or rough was high, and a good tactile feel was not obtained after processing. On the other hand, even if the score for smooth, silky, or moist was high, if the resin sheet had poor cushioning, it was marked with "△."

[0055] (3) Bending resistance evaluation For the prepared resin sheet, a cantilever-type bending resistance tester was used in accordance with Method A (45° cantilever method) described in JIS L 1096:2010, 8.21.1. Five 20 mm × 150 mm test pieces prepared in accordance with Clause 6 of JIS L 0105 were taken in each of the longitudinal and transverse directions, and measurements were taken on the front and back of each of the five pieces, and the average value was taken as the bending resistance in this example. Measuring device: Cantilever type bending resistance tester (manufactured by Daiei Chemical Industry Co., Ltd.) ·Measurement environment: temperature 23℃, humidity 50%

[0056] (4) Compression work evaluation Three 200mm x 200mm test pieces were prepared from the prepared resin sheet, and the compression work load was measured when compressed from the side having the hair-like bodies using a compression tester, and the average value was used as the compression work load in this example. Measurement equipment: Compression tester KES-FB3-A (manufactured by Kato Tech) ·Measurement environment: temperature 20℃, humidity 65% Compression speed: 20μm / sec Maximum compression load: 10gf / cm 2 Pressure plate area: 2.0cm 2

[0057] (5) Basis weight evaluation For the produced resin sheet, 20 test pieces of 200 mm x 250 mm were prepared, and the basis weight of each was measured according to JIS P8124 (2011), and the average value was taken as the basis weight in this example. ·Measurement environment: temperature 23℃, humidity 50%

[0058] (6) Tensile strength evaluation Five test pieces of 150 mm x 10 mm were prepared from the prepared resin sheet, and the stress at the time of sheet breakage was measured in accordance with JIS K 7161, and the average value was taken as the tensile strength in this example. Measurement equipment: Universal material testing machine Strograph VE1D (manufactured by Toyo Seiki Co., Ltd.) Chuck distance: 50mm Pulling speed: 50mm / min ·Measurement environment: temperature 23℃, humidity 50%

[0059] (7) Tear strength evaluation Five test pieces for right-angle tearing were prepared from the prepared resin sheet, and the stress at the time of sheet breakage was measured in accordance with JIS K 7128-3, and the average value was taken as the tear strength in this example. Measurement equipment: Universal material testing machine Strograph VE1D (manufactured by Toyo Seiki Co., Ltd.) Chuck distance: 40mm Pulling speed: 200mm / min ·Measurement environment: temperature 23℃, humidity 50%

[0060] (8) Sewing processability evaluation The resin sheet was folded over and the folded portion was sewn together using a sewing machine. The evaluation of the sewing processability was performed by observing the appearance of the sewn portion. The evaluation criteria were as follows: ○: If the sewing process was performed without any problems, it was marked as ○; ×: if burrs or cracks were formed.

[0061] (9) Formability during extrusion molding When the resin sheet was taken up using the pinch roll, it was marked with a circle if it could be taken up without any problems, and marked with an X if it was wrinkled and could not be taken up properly or was torn.

[0062] (Production of a resin sheet having hair-like bodies) [Examples 1 to 6] A blend (weight ratio 95:5) of (A-1) or (A-2) thermoplastic resin and (A-3) release agent masterbatch (which form the capillary and underlayer layers) was fed from a 40 mm single-screw extruder, and (B) fiber sheet (which forms the fiber sheet layer) was fed from a feeding device. (A) was cast between a transfer roll with a textured surface, which had been treated with chromium oxide spraying and laser engraving and adjusted to 60 ° C to 150 ° C, and a silicone rubber touch roll with a rubber hardness of 70 adjusted to 10 ° C to 90 ° C. The (B) fiber sheet was inserted while following the touch roll, and laminated simultaneously with casting, and taken up at a line speed of 1 m / min to 15 m / min using a pinch roll. This produced a resin sheet with the composition, thickness, and surface shape shown in Table 1.

[0063] [Comparative Examples 1 and 2] A blend (weight ratio 95:5) of (A-1) or (A-2) thermoplastic resin and (A-3) release agent masterbatch (which form the capillary and underlayer layers) was poured from one 40 mm single-screw extruder, and (C) thermoplastic resin (which forms the base layer) was poured from one 65 mm single-screw extruder. The resin sheet extruded by the co-extrusion multilayer T-die method (feed block method) was then subjected to chromium oxide spraying and laser engraving to create a textured transfer roll adjusted to 60 ° C to 150 ° C, and a silicone rubber touch roll with a rubber hardness of 70 adjusted to 10 ° C to 90 ° C. The resin sheet was then cast using a pinch roll at a line speed of 1 m / min to 15 m / min. This resulted in a resin sheet with the composition, thickness, and surface shape shown in Table 1.

[0064] [Comparative Examples 3 and 4] A blend (weight ratio 95:5) of (A-1) or (A-2) thermoplastic resin and (A-3) release agent masterbatch, which form the capillary bodies and undercoat layer, was poured from a 40 mm single-screw extruder. The extruded resin sheet was then subjected to chromium oxide spraying and laser engraving to create a textured transfer roll adjusted to 60°C to 150°C, and a silicone rubber touch roll with a rubber hardness of 70 adjusted to 10°C to 90°C. The sheet was then cast using a pinch roll at a line speed of 1 m / min to 15 m / min. This yielded a resin sheet with the composition, thickness, and surface shape shown in Table 1.

[0065] Using the resin sheets obtained in each of the Examples and Comparative Examples, evaluation tests were carried out on various properties, and the results are shown in Table 1.

[0066] [Table 1]

[0067] The results shown in Table 1 reveal the following: It was shown that all of the resin sheets of Examples 1 to 6 had a good feel and could be sewn. On the other hand, the resin sheet of Comparative Example 1 is a conventional resin sheet having a base layer, hair-like bodies, and a base material layer, but has a high bending resistance, a low compression work load, and a high basis weight, which results in poor tactile feel in terms of flexibility and compressibility, and when sewn, cracks appear at the folded parts and from the marks of the sewing machine needle, making it problematic as a sewn product. Furthermore, the high basis weight causes a feeling of weight. The resin sheet of Comparative Example 2 had a thicker base layer and a higher compression work load than the resin sheet of Comparative Example 1, but because it had a base layer, cracks appeared at the folded parts when sewn and from the marks of the sewing needle, which was problematic as a sewn product. There was also the problem that the basis weight was even higher, making the product feel heavier. The resin sheet of Comparative Example 3 was a single-layer resin sheet made of a thermoplastic resin composition, but had a low compression work load, a texture lacking cushioning, and an unfavorable feel. The resin sheet of Comparative Example 4 had a thicker base layer than the resin sheet of Comparative Example 3, resulting in a higher compression work load, but the basis weight was also higher, resulting in a problem of a heavy feel.

[0068] Although the present invention has been described above using various embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Industrial Applicability]

[0069] The resin sheet of this embodiment can be sewn, has cushioning properties, and has a reduced weight, so that even after sewing, it is possible to provide processed products that have cushioning properties and a reduced weight, and has industrial applicability. [Explanation of symbols]
