The present invention relates to a novel composite sheet material that has a feel similar to that of natural suede leather and has physical performance, particularly strength, as an artificial leather. Conventionally, the base fabric for artificial leather and its manufacturing method has been to use sea-island fibers, blended fibers and splittable fibers, to make them into non-woven fabrics using dry non-woven fabrics such as cards and needle punches, and then to make sea-island fibers, blended fibers and splittable fibers. It is known that nonwoven fabrics made of ultrafine fibers can be made by extracting or splitting the fibers. However, these nonwoven fabrics have a problem of poor dimensional stability (poor elongation recovery). In order to solve the above-mentioned problems of non-woven fabrics, for example, Japanese Patent Application Laid-Open No. 52-107368 and Japanese Patent Application Laid-Open No. 53-122869
As seen in the above publication, it has been proposed to three-dimensionally intertwine and integrate ultrafine fibers and knitted fabrics. In this case, the physical performance of the product depends on the knitted fabric, and the ultrafine fibers particularly contribute greatly to the effect of significantly improving the tactile feel of the sheet. However, even in this case, when knitted fabrics are used, although strength and drapability can be imparted to the product, poor dimensional stability (large amount of residual deformation) results in artificial leather products for clothing. This has the problem of causing so-called "elbow drop". In addition, when a woven fabric is used, although it has excellent dimensional stability, it has the disadvantage of low seam strength because the texture of the woven fabric tends to sag (particularly when wet) even in the product. Moreover, there is also the problem that "fraying" occurs at the cut edges when cutting. Therefore, the present inventors conducted extensive research in order to solve the problems in intertwined bodies of ultrafine fibers and textiles, and as a result, they arrived at the present invention. That is, the present invention provides a sheet-like article mainly made of ultrafine fibers, woven fabrics, and elastic polymers with a fineness of 0.5 d or less, in which the fibers constituting the woven fabric are made of false twisted yarn with a single yarn fineness of 3 d or less. The twisted yarn has a twist of 200 to 1200 T/m, and the ultrafine fibers cover at least one entire surface of the fabric and are integrated with the fabric through three-dimensional entanglement, and an elastic polymer is inserted into the interstitial spaces of the entangled body. This is a composite sheet material characterized by containing. To explain the present invention in more detail, the sheet-like article of the present invention has ultrafine fibers and a woven fabric that are three-dimensionally entangled and integrated, at least one side of the woven fabric is covered with the ultrafine fibers, and an elastic polymer is contained inside the structure. It contains. Its physical performance is highly dependent on the fabric, and the ultrafine fibers primarily contribute to the effect of significantly improving the tactile feel of the sheet. Elastic polymers, on the other hand, emphasize these two effects, namely, the physical performance of the fabric and the improvement in touch and feel due to the ultrafine fibers. In this case, what is particularly important is the intertwining state of the ultrafine fibers and the fabric. It has been found that physical properties suitable for clothing applications, particularly seam strength and tear strength, are greatly influenced by this entangled state. It has been found that it is extremely effective to apply the fabric specified in the present invention in order to obtain suitable performance. As in the present invention, it is observed that by twisting the false twisted yarn constituting the fabric, the entanglement between the ultrafine fibers and the false twisted yarn is controlled. That is, the degree of entanglement between the ultrafine fibers and the single yarns constituting the false twisted yarn increases or decreases depending on the number of false twists. This fact greatly influences the physical properties of the product. The woven fabric of the present invention is made of false twisted yarns for both the warp and weft, and the false twisted yarn also includes
It is necessary to have a twist of 200 to 1200 T/m, preferably 500 to 1000 T/m. If there is no twist or the number of twists is low, such as less than 200 T/m, the tear strength of the resulting product will be extremely low. on the other hand,
In the case of a high twist number of 1200 T/m or more, the seam strength when wet is insufficient and "raveling" becomes noticeable when cutting. 200~ of the present invention
Tear strength and seam strength can only be satisfied at the same time when the number of twists is 1200T/m. The fabric weight of the present invention is 20 to 100 g/m 2
is preferable, more preferably 30 to 70
g/ m2 . Furthermore, sheet-like materials have good physical properties,
In particular, in order to impart tear strength, it is desirable that the toughness of the false twisted yarn T S ×√ E (T S is the tenacity g of the raw yarn, T E is the elongation % of the raw yarn) is 1250 or more. In the present invention, by intertwining the fabric made of ultrafine fibers and false twisted yarn, the false twisted yarn is fixed and the mesh of the fabric can be prevented from shifting. It is preferable to use processed yarn with a large toughness T S ×√ E. More preferably, by using the fabric of the false twisted yarn of the present invention, the problem of "fraying" during cutting will not occur due to the entanglement with the ultrafine fibers and impregnation with the elastic polymer. . The structure of the fabric of the present invention is preferably plain weave, which is the easiest to weave, has a flat texture, and is durable. It is preferable that the single filament fineness of the fibers constituting the woven fabric is 3d or less; if it is 3d or more, the fabric becomes too hard to be used as a base fabric for artificial leather for clothing. The type of fiber is not particularly limited, and includes, for example, fiber-forming synthetic polymers such as polyester, polyamide, and polyacrylonitrile, and semi-synthetic fibers such as acetate, with polyester and polyamide being preferred.
Further, the false twisted yarn can be manufactured by a known manufacturing method such as a spindle method, a frenchion method, and a one-heater or two-heater type. Also, the twist direction is S twist, Z twist
Either twist is acceptable. The ultrafine fibers of the present invention must have a diameter of 0.5 d or less, and the ultrafine fibers are raised to give a good suede effect. If the fineness is larger than this,
In addition to impairing the flexibility of the resulting artificial leather, the surface of the artificial leather loses its fineness and has a rough feel, which is undesirable because it loses the moist feel of natural leather. There is no particular limitation on the type of fiber material as long as it satisfies the above fineness. For example, synthetic polymers such as fiber-forming polyester, polyamide, polyacrylonitrile, polyolefin, copolymers or copolymer mixtures containing the above polymers as main components, or rayon, copper, ammonia rayon, etc. It may also be recycled fiber. In the present invention, such ultrafine fibers cover at least one entire surface of the fabric and are integrated with the fabric by three-dimensional entanglement. Therefore, the composite sheet-like products of the present invention include those consisting of an ultrafine fiber layer/fabric layer and those consisting of an ultrafine fiber layer/fabric layer/microfiber layer. Elastic polymers are contained in the interstitial spaces of such entangled bodies. As the elastic polymer, it is preferable to use a polyurethane elastomer. The content is preferably 30 to 100% by weight of the total fiber weight of the ultrafine fibers and fabric. Such a composite sheet-like material can be prepared by
Dyed and brushed. An example of the method for manufacturing the composite sheet product of the present invention will be explained. First, the ultrafine fiber sheet is processed by, for example, the carding method,
Formed by paper making method, melt blowing method, etc.
The fabric of the present invention was placed on one side of the obtained sheet.
A laminated sheet with a three-layer structure or a three-layer structure is formed by sandwiching the fabric of the present invention between the two obtained sheets. Next, the sheet and the fabric are intertwined together by an interlacing process. Particularly preferred means that by spraying a high-pressure liquid jet, the ultrafine fibers of the laminated sheet are three-dimensionally entangled with each other, and the monofilaments constituting the fabric and the ultrafine fibers are partially entangled so as to prevent the fabric from shifting. A composite sheet is formed by intertwining the microfiber nonwoven fabric component with the woven fabric.
As the high-pressure jetted liquid stream for three-dimensionally entangling the ultrafine fibers and the fabric, it is particularly preferable to use water since it is inexpensive. This allows the ultrafine fibers and the fabric to be entangled without damaging the fabric. As other methods, known means such as the needle punch method can also be applied. Additionally, the composite sheet is impregnated with an elastomeric polymer to enhance the tactile feel of the microfiber sheet and to emphasize the physical performance of the fabric. The method for measuring seam strength and tear strength is explained below.
The present invention will be explained in more detail with reference to Examples. [Seam strength] Conforms to JIS L-1093. Test samples were tested under dry and wet conditions (test specimens were
(soaked in water for 1 minute). [Tear strength] According to JIS-L-1079 c method and pendulum method. Example 1 500g of short polyester microfibers with a fineness of 0.15d cut into 5mm pieces were added to 600ml of water to create a dispersion, and then 2 ml of a 0.5% aqueous solution of polyacrylamide was added to this dispersion. 200cps
A slurry liquid with a viscosity of 100 g/m 2
A short fiber paper sheet was obtained. On this paper sheet, 50 denier/36 polyester with a basis weight of 40 g/ m2 is applied.
A plain woven fabric made of the false twisted yarn listed in Table 1 of the filament is placed as warp and weft, and a sheet with the above-mentioned basis weight is placed on top of it to form a three-layer structure. A high-pressure water jet is applied continuously at a pressure of 10 kg/cm 2 from a nozzle with a diameter of
By treating the front and back surfaces once each under a pressure of cm 2 , a three-dimensionally entangled composite sheet with a smooth surface was obtained. After drying, the composite sheet was impregnated with a 10% DMF solution of polyurethane elastomer, then coagulated and dried. The amount of polyurethane attached at this time is based on the amount of fiber in the sheet.
It was 65%. When the sheet obtained in this way was dyed and raised, extremely dense naps were obtained on the surface.
A suede-like sheet material with a good feel was obtained. When the seam strength and tear strength of this sheet-like material were measured, the values shown in Table 1 were obtained, and it was found to have extremely good strength as a material for clothing. Furthermore, even when this sheet-like material was cut during sewing, no "raveling" was observed during cutting. Comparative Example 1 The basis weight on a sheet made by the method of Example 1
A 40g/ m2 50 denier/36 filament polyester false-twisted yarn with different number of twists and toughness was placed on top of it, and the above-mentioned paper sheet was then placed on top of it to form a three-layer structure sheet and heated under high pressure in the same manner as in Example 1. A jet liquid stream was applied to obtain a three-dimensionally entangled composite sheet, which was then coated with polyurethane, dyed, and raised.

Apply pressure once, then press the paper sheet side 10 times.
Apply it once with a pressure of Kg/cm 2 , and apply it twice with a pressure of 35Kg/cm 2 on the melt blown web side, and apply it twice with a pressure of 35Kg/cm 2 on the paper sheet side.
A three-dimensional entangled and integrated composite sheet product was obtained by applying a pressure of 25 kg/cm 2 twice and finally applying a pressure of 5 kg/cm 2 to the melt-blown web side and the paper sheet side once each. Ta. When this sheet material was coated with polyurethane, dyed, and raised in the same manner as in Example 1, a soft-textured sheet material with a texture very similar to natural leather was obtained. The seam strength and tear strength of this sheet were measured, and as shown in Table 2, it showed extremely excellent strength as a material for clothing. Furthermore, when this sheet material was cut during sewing, no "raveling" was observed at all during cutting.
