Embodiment 1

[0144] As the interior skin material used in the interior molding of Example 1, a woven fabric of heat-treated polyethylene terephthalate semi-drawn yarn (POY) was used.

[0145] The polyethylene terephthalate semi-drawn yarn (POY) used is a denier of 132dtex, a black spun-dyed yarn of 48 filaments (maximum stress elongation 134%). like Image 6 As described above, the semi-drawn yarn was run at a speed of 200 m / min in a hollow heater with a length of 1 m and a temperature of 190° C., and dry heat treatment was performed at an elongation ratio of 0. Then, a processed yarn with a temporary yield point stress of 86cN / dtex, a maximum stress of 258cN / dtex, a maximum stress elongation of 137%, and a boiling water shrinkage (boiling water shrinkage) of 3% measured by the JIS L1013A method was produced, and interlaced After that, coiling is performed.

[0146] After weaving the processed yarn at a warp density of 124 threads / 25.4mm and a weft thread density of 118 threads / 25.4mm, i...

Embodiment 2

[0159] The semi-drawn yarn (POY) of polyethylene terephthalate uses gray dope-dyed yarn with a fineness of 97dtex (134% elongation), and makes it in a 1m hollow heater (190°C) Travel at a speed of 200m / min, and perform dry heat treatment at an elongation ratio of 0. Then, a processed yarn with a temporary yield point stress of 59cN / dtex, a maximum stress of 172cN / dtex, a maximum stress elongation of 135%, and a boiling water shrinkage (boiling water shrinkage) of 3% measured by the JIS L1013A method was produced, and interlaced After that, coiling is performed. The processed yarn was knitted into a tricot fabric using a 3 bar tricot machine (28 gauge). Heat setting was carried out at 100°C to produce a braided fabric with a wale density of 68 threads / 25.4mm and a course density of 70 threads / 25.4mm. Next, in the same manner as in Example 1, a flexible polyurethane foam sheet having a thickness of 4.2 mm was adhered as a base material by frame lamination, and then a grid patt...

Abstract

The present invention relates to an interior molded body and a method for producing the same. The press-molded interior molded body formed by laminating the interior skin material and the base material has a portion with the least expansion and contraction deformation and other portions. The point of the interior skin material is that the first region When N1 is the number of warp threads present in , and N2 is the number of weft threads present in the second area, and the interval of the second area is adjusted so that the warp threads existing in the second area are equal to N1 and the latitude threads are equal to N2 , the length of each side of the second region is the ratio of the length of each side of the corresponding first region to a predetermined range.

Description

technical field [0001] The present invention relates to an interior molded body and a method for producing the same. Background technique [0002] Conventionally, an interior molded body obtained by molding a laminated body formed by laminating a base material and a skin material into a predetermined shape is known. This interior molded article is used as a molded article for vehicles, a molded article for housing, and the like. [0003] For example, Japanese Unexamined Patent Application Publication No. 62-142628 discloses an interior molding in which a skin material and a base material are adhered. [0004] In an interior molded product obtained by press-molding a sheet-like laminate obtained by laminating a base material and a skin material in advance, wrinkles may appear in the skin material or the pattern of the skin material may be distorted. Due to the distortion of the wrinkle and the pattern, the appearance of the interior molded article deteriorates and the produ...
