Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an interior skin material used for automobile interior parts, such as seats, headrests, door trims, vehicle seats, and ceiling panels.

[Prior art]

Traditionally, materials such as the backs of car doors and ceilings were made of wood mat molding material or thermoplastic resin molded material with 7-aplyx skin material adhered to the surface, but recently it has been used for the entire interior of the car, In addition, there is a tendency to use molded fabric skin materials for sheets, woven or knitted fabrics with appropriate elongation. Thread Section 1 A fabric made of stretchable fibers is used as the skin material.

[The interlayer point that the invention attempts to solve]

Regarding the above skin materials, in order to unify the interior design, for example, the seat skin and door trim skin have the same color, pattern,
Consideration has been given to using materials with piles, that is, materials with the same appearance, but no consideration has been given to matching the weave or stitch pitch after molding.

In particular, as molding methods have become more diversified in recent years, depending on the molding method, the carpet or stitch pitch after molding may become uneven between areas that are strongly squeezed during molding and flat areas that are not. For example, in addition to the above-mentioned method of layering a skin agent on the surface of the molding base material, there is a method of molding a laminate with a synthetic resin sheet, or a method of integrally joining and molding with a 1 m melted resin in a mold. However, in these methods, the skin material is deep drawn (the elongation after forming is 0 to 2).
00 S or more. If the weave pattern or stitch pitch is uniform as in conventional skin materials, the density will be coarse in the drawn portions, resulting in defects in appearance.

The present invention has been devised in view of the above problems.

The aim is to provide an interior skin material having a uniform weave or stitch pitch in any part of the vehicle interior.

[Means to solve the problem]

゛ In the automobile interior skin material of the present invention, each part of the fabric has a different molding shrinkage rate so that the weave or S-pitch pitch of the cloth in the drawing part after molding is equal to the standard pitch in the flat part. In addition, there is a pitch that is higher than the standard pitch and is characterized by a pitch that is higher than the reference pitch.

[Function] If the weave or stitch spacing of the unformed skin material and the molded skin material is a and the molding elongation rate (or molding rate) is human, then as shown in the example below, the paper = b. Become.

Earthworks Upper 1/1 1/1 ”/1 Therefore, the higher the molding strength of the skin material used for drawn-formed parts, the higher the stitch pitch, that is, the narrower the stitch pitch, if the skin material is provided with weave or stitches with a narrower stitch pitch, it will be easier after forming. The distance between the stitches becomes uniform.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a perspective view of the interior parts of the vehicle, with numeral 2 representing a seat, 2 a door trim, 3 a pillar garnish, and 4 an instrument panel. The door trim 2 includes a deep-drawn door trim, a molded door trim, and a flat plate door trim, and the door trim 2 in FIG. 691 corresponds to a deep-drawn door trim. Pillar 12 723 is a molded door trim base that is drawn, and the instrument panel 4 is a deep-drawn molded product. Note that the skin materials used for these parts were all knitted products, and the skin material of the sheet 10 was unformed and had a standard stitch pitch.

Figure 2 shows the structure of pearl weave, which is a type of stockinette, and is usually used for outer clothing because it has great elasticity in the vertical and horizontal directions. Figure 3 shows three types of stockinette structures 5, 6.7 with different Al 14 stitch pitches, and the distance between the loops 8 is dl+
Since dQsd3 is 1/1 : 2/a : 1/2, if the stockinette structure 6 and 7 is formed at an elongation rate of 3/2.2/1, the same structure as the unformed stockinette structure 5 will be obtained.

Note that the stitch pitch of the skin material can be freely changed in the vertical and horizontal directions by adjusting the coarse density of the knitting needles of the knitting loom.

〔Effect of the invention〕

As mentioned above, in the skin material of the present invention, the weave or stitch pitch of the fabric is changed depending on the degree of the drawing process so that the stitch pitch after forming is uniform, so that the stitch pitch after forming is uniform. A product with uniform texture and good texture can be obtained.

[Brief explanation of drawings]

FIG. 1 shows a perspective view of an automobile interior part, and FIG. 2 shows a plan view of one row of stockinette weave. FIG. 3 shows a schematic diagram of a molded knitted fabric. In the figure.

Claims (1)

[Claims] The fabric is woven or knitted at a pitch higher than the standard pitch for each area with different molding elongation rates so that the weave or stitch pitch of the fabric in the drawing area after forming is equal to the standard pitch in the flat area. Automotive interior skin material.
