ルシートは得られていない。[Problems to be solved by the invention] When attempting to form an uneven pattern using an embossing roll on the pile surface of a vinyl chloride sheet electrostatically flocked, the base is vinyl chloride which easily melts, and strong radiant heat from the embossing roll is applied. Because of this, the vinyl chloride sheet is easily deformed, especially at the pressed location, and therefore, a vinyl chloride sheet with electrostatic flocked piles with sharp mold edges and a complex and delicate embossed pattern has not been obtained.

。The electrostatic flocking sheet fabric according to the present invention is in accordance with the above-mentioned purpose, and the pile surface of the electrostatic flocking sheet is made by electrostatically flocking pile pieces of thermoplastic synthetic fibers based on a heat-melting resin sheet. Print black, graphite, carbide, or other black body fine particles, irradiate the black body with near infrared rays to generate heat to the extent that the pile pieces heat shrink, and heat shrink and melt the pile through the black body to create an uneven pattern. It is characterized by the fact that it has been formed.

７ ｍ ／分で静電植毛シートを通過させる。A black body is printed on the pile surface of the electrostatic flocking sheet, and near-infrared rays are irradiated to heat only a very limited portion of the attached pile, the synthetic IJk fibers, through the heat-generating black body. The method is described in Japanese Patent Application No. 142142/1982 and Japanese Patent Application No. 46/1983, which the present inventors invented and filed earlier.
309, etc., and the present invention also utilizes it, but to briefly explain the method,
Infrared rays range from 0.72μ to 1 between visible light and microwaves.
It has a wide wavelength band up to 000μ, and depending on the wavelength band, infrared rays in the wavelength band from 0.72μ to 1.5μ are considered near infrared rays, and infrared rays in the wavelength band from 1.5μ to 5.6μ are considered mid-infrared, Infrared rays in the wavelength band from 5.6μ to 1000μ are classified as far infrared rays, and in the present invention, near infrared rays in the wavelength range from 0.72μ to 1.5μ in these wavelength bands, especially wavelengths around 0.75μ (750mμ), are classified as far infrared rays. It is commonly used by irradiating the pile surface with an infrared irradiation lamp that mainly emits near-infrared rays.More specifically, a unit length (m) that emits near-infrared rays with a main wavelength of around 750m71 by attaching or imprinting a black body. A cylindrical near-infrared lamp with a per output of about 2 kW can be used at close ranges of 30 to 70 meters at a speed of 3 to 3.
Pass through the electrostatic flocking sheet at 7 m/min.
因に、黒体はこの様に至近距離から近赤外線を強く照射
した場合にのみ熱可塑性合成繊維を熱変形させる程度に
発熱するが、通常の日光や照明燈の光に含まれている少
量の近赤外線によっては殆ど発熱せず熱可塑性合成繊維
を熱変形させることはない。Incidentally, a black body generates heat to the extent that it thermally deforms thermoplastic synthetic fibers only when it is strongly irradiated with near-infrared rays from a close distance, but a black body generates heat to the extent that it thermally deforms thermoplastic synthetic fibers. Near-infrared rays generate almost no heat and do not thermally deform thermoplastic synthetic fibers.
黒体を付着乃至印捺する手段や方法については限定され

以下で繊維を黒く着色しない程度の極く微量付着乃至印
捺すれば好い。つまり、本発明における黒体を付着乃至

い。There are no restrictions on the means or method for applying or imprinting the black body, but the amount of the black body applied is 0.1% by weight of the thermoplastic synthetic fiber.
In the following, it is sufficient to apply or print a very small amount so as not to color the fibers black. In other words, the purpose of attaching or printing a black body in the present invention is not to color thermoplastic synthetic fibers.

ある。According to the present invention, only a very limited pile of attached synthetic fibers is heated and melted and shrunk by near infrared rays through a black body to form an uneven pattern on the pile surface of the electrostatic flocking sheet. During this process, no thermal deformation occurs in the surrounding piles to which the black body is not attached and the thermofusible resin sheet that is the base of the electrostatic flocking sheet, and the four parts of the pile surface that are recessed due to heat melting and shrinkage do not occur. Since the black body is present, the color contrast with the convex parts becomes clear, and therefore, an electrostatic flocked sheet with a complex IJII 8I uneven pattern with sharp edges, which could not be obtained by conventional embossing, can be obtained.
Moreover, since it is based on a thermoplastic resin sheet such as woven or knitted fabric or non-woven fabric that does not fit the substrate 41, deep drawing is easy, and it can be cut by heating and melting at the same time as welding. It is extremely convenient as a vehicle interior material.
