防止を図つた表皮材が提案されている。(Prior Art) Seat upholstery materials made of fabrics that have a soft surface feel and excellent decorative properties are preferred. However, when fabric alone is used as the skin material, when cutting and sewing the skin material to form a shape that covers the surface of the seat cushion, the fabric has good flexibility (deformability) and elongation, so the skin material The material is often cut or sewn in a distorted manner, and sewing wrinkles are likely to occur in the outer material.
In addition, since twisting caused by distortion of the skin material during cutting and sewing occurs in the skin material when it is attached to the cushion body, the skin material tends to be lifted from the surface of the cushion body due to the twisting, and this also causes the skin material to become loose from the surface of the cushion body. This may cause wrinkles in the wood. Furthermore, the handle or pattern of the upholstery may become distorted, and if the upholstery is made of pile weave, the pile may easily come off due to rubbing of the upholstery surface when the seat is seated. Therefore, a skin material has been proposed in which a layer of resin such as acrylic resin latex is applied to the back side of the fabric and cured.The cured resin layer makes it difficult for the fabric to become distorted during cutting and sewing, and also prevents the pile from falling out. has been done.

る。(Problems to be Solved by the Invention) The present invention has been devised in view of the above-mentioned points, and is designed to prevent the occurrence of wrinkles and misalignment of patterns and patterns due to distortion during cutting and sewing, without impairing the soft surface feel of the fabric. Another object of the present invention is to provide a seat skin material that solves the problem of pile shedding.

ある。(Means for Solving the Problems) The gist of the present invention is that an elastic foam raw material is applied to the back surface of a surface member made of fabric, and a thin layer of elastic foam is adhesively formed. This seat skin material is characterized in that a back surface member made of woven fabric or non-woven fabric is adhered to the back surface of the layer.

発生を防ぐことができる。(Function) Since the surface member has a thin layer of elastic foam adhered to its back surface, it stretches and deforms together with the thin layer of elastic foam, and its elongation and flexibility are reduced. The thin layer of elastic foam will be limiting. Moreover, the thin layer of elastic foam
Since it is directly formed from the elastic foam raw material applied to the back surface of the surface member, grooves are formed on the thin layer surface of the elastic foam in the areas where the weaving or knitting yarns of the surface member exist, and the grooves The weaving yarn or knitting yarn of the surface member is partially stuck in the area. Therefore, the adhesive area between the weaving yarn or knitting yarn of the surface member and the thin layer surface of the elastic foam becomes large, and the weaving yarn or knitting yarn is sandwiched in the grooves and firmly fixed, so that the surface member The member and the thin layer of elastic foam are more reliably integrated, and the original texture or stitch shape of the surface member is maintained, so that the elongation and flexibility of the surface member can be effectively suppressed. As a result, distortion and deformation during cutting and sewing of the skin material can be reduced and wrinkles can be prevented.

ても、そのパイルの根元が弾性発泡体の薄層表面
の前記凹溝部に強固に接着しているため、座席着
座時における着座者と表皮材表皮材との擦れ合い
によつてもパイルの抜けが生じにくくなる。 Furthermore, even if the surface member is made of pile weave, the roots of the pile are firmly adhered to the grooves on the surface of the thin layer of the elastic foam, so that when the seat member is seated, the surface material The pile is less likely to come off due to friction.

けを生じやすい欠点がある。 On the other hand, if a separately formed thin layer of elastic foam with a flat surface is adhered to the back side of the surface member with adhesive, the surface of the elastic foam is flat, so The weaving yarn or knitting yarn does not get stuck in the surface of the elastic foam as described above, and not only does the effect of maintaining the texture or the stitch shape of the surface member is small, but also the adhesion area between the surface member and the elastic foam is small. Since the adhesion force is not so large, the elongation and flexibility of the surface member cannot be effectively suppressed, and furthermore, there is a drawback that peeling of the surface member and pile shedding when the surface member is a pile weave are likely to occur.

損ねることもない。 On the other hand, regarding the feel of the surface of the skin material, the thin layer of elastic foam on the back of the surface member has elasticity, unlike a cured resin layer made of latex, etc., so its elasticity makes the surface of the skin material soft to the touch. Become something. In addition, if the thin layer of elastic foam is formed from a polyurethane emulsion, the polyurethane emulsion is applied to the back surface of the surface member in a foamed state when forming the thin layer of elastic foam, and unlike ordinary polyurethane raw materials, the polyurethane emulsion is applied to the back surface of the surface member. Since it is difficult to penetrate and does not ooze out onto the surface of the surface member, the oozing raw material will not stain the surface of the surface member, nor will the oozing raw material harden and impair the soft feel of the surface of the surface member.

が図られる。 Furthermore, in the seat skin material of the present invention, a back member is bonded to the back surface of the thin layer of elastic foam, and the back member suppresses elongation and deformation of the thin layer of elastic foam. And the deformation is also limited by the back member,
Since distortion of the skin material is less likely to occur during cutting and sewing, wrinkles or misalignment of the pattern and pattern are less likely to occur. Moreover, the back surface member not only protects the thin layer back surface of the elastic foam, but also improves the flame retardancy of the skin material and the slippage of the back surface when the skin material is applied.

This is to make the surface feel soft, and if the surface member 12 is made of pile weave, it is to prevent the pile from coming off. This thin layer 14 of elastic foam is formed by heating and curing a polyurethane emulsion applied to the back surface of the surface member 12 to a predetermined thickness using a doctor knife or the like.
It usually has a thickness of about 0.5 to 2 mm. Various known polyurethane emulsions can be used, but for example, a polyurethane emulsion obtained by emulsifying a polyurethane solution, or a polyurethane prepolymer consisting of a polyether polyol or polyester polyol and a polyisocyanate is emulsified, and a chain extender is added thereto. Examples thereof include polyurethane emulsions whose chains have been extended by polyurethane emulsion, and polyurethane emulsions containing conjugated diene and/or vinyl polymer emulsions. This polyurethane emulsion is mixed with air and foamed by a foaming machine, applied to the back surface of the surface member 12 in a foamed state, and cured by subsequent heating without seeping onto the surface of the surface member 12. is adhered to form a thin layer 14 of elastic foam. The elastic foam thin layer 14 formed in this way has a concave groove 20 at the adhesive part with the weaving yarn or knitting yarn 18 of the surface member, as shown in FIG. 2 which shows an enlarged view of part A. The weaving yarn or knitting yarn 18 of the surface member is partially fitted into the concave groove portion 20 without being buried.
