Problems solved by technology

However, nylon nonwoven fabric is expensive and is a raw material with weak weather resistance
At present, non-woven fabrics made of polyolefin materials or non-woven fabrics made of polyester materials are used as cheaper materials than nylon, but non-woven fabrics made of polyolefin materials are excellent in foldability and flame retardant. , Weak weather resistance, and non-woven fabrics made of polyester materials have excellent weather resistance and flame retardancy but poor foldability, so neither of them is practical

Embodiment 1～3

[0190] Manufactured by a spunbond method from the raw materials shown in Table 1 described later, the phosphorus-containing compound (2-carboxyethyl) phenylphosphinic acid ((2-carboxyethyl)phenylphosphinic acid) was polymerized in the amount shown in Table 1, By calendering with a hot roll at 210° C., sheets of the specifications shown in Table 1 having a random loop structure composed of polyester fibers of 1.5 decitex were heat-compressed to obtain molding substrates.

[0191] A 30 μm polyethylene-based film was laminated on the shaped base thus obtained. This laminate was molded at 120° C. together with a polyurethane foam raw material to manufacture an automobile roof material having this laminate as the lowermost layer. The punched waste of the laminate produced at this time was reused as a polyester fiber raw material for the rough felt.

[0192] In addition, a laminate of the above-mentioned nonwoven fabric and the above-mentioned film was used as an air bag wrapping m...

[0194] Manufactured by the spun-bonding method, the phosphorus-containing compound (2-carboxyethyl) phenylphosphonic acid was copolymerized in the amount shown in Table 1 described later, and processed by calendering with a hot roll at 235°C. 20g / m of random ring structure composed of mixed fiber of polyethylene terephthalate and polyester artificial rubber 2 The thin plates were heat-compressed to obtain a shaped substrate.

[0195] A 30 μm polyethylene film was laminated on the obtained molding base material. This laminated body was molded together with a polyurethane foam raw material, and the automobile roof material which made this laminated body the lowermost layer was manufactured. The punched waste of the laminate produced at this time was reused as a polyester fiber raw material for the rough felt.

Embodiment 5～9

[0197] Manufactured by the spunbond method, the phosphorus-containing compound (2-carboxyethyl) phenylphosphonic acid was copolymerized in the amount shown in Table 1 below, and processed by calendering with a hot roll at 210°C. 20g / m mesh of random annular structure composed of polyester fibers mixed with more than two kinds of raw materials shown in Table 1 2 The thin plates were heat-compressed to obtain a shaped substrate.

[0198] For soft PET, by combining 100 parts of terephthalic acid, 40 parts of ethylene glycol, and 15 parts of neopentyl glycol with a small amount of catalyst, transesterification is performed by the usual method-after polymerization An aromatic copolyester having a melting point of 178° C. and an intrinsic viscosity of 0.780 obtained by pelletizing.

[0199] A 30 μm polyethylene film was laminated on the obtained molding base material. This laminate was molded at 120° C. together with a polyurethane foam raw material to manufacture an automobile ro...

Abstract

A non-woven fabric for manufacturing a vehicle formed article, which exhibits a tensile modulus at 5 % elongation of 0.1 to 20 N / 5cm at 120 1 / 2 C, wherein it has a weight of 100 g / m<2> or less, and an apparent density of 0.08 to 0.40 g / cm<3>, and a fiber diameter of a fiber constituting it may be 1 to 100 mum. The non-woven fabric may comprise a fiber comprising a polyester based material selected from the group consisting of polytrimethylene terephthalate, polybutylene terephthalate, a mixture of polytetramethyleneoxideglycol and polybutylene terephthalate, a polyester elastomer, and an amorphous polyester.

Description

technical field [0001] The present invention relates to a nonwoven fabric for forming a vehicle molded body that can be suitably used as a molded body for a vehicle or a part thereof, and more particularly to a nonwoven fabric for forming a vehicle molded body that improves the recyclability of cut waste. cloth. Background technique [0002] Conventionally, as materials for forming vehicle moldings such as roof materials, trunk materials, and carpet materials, materials having such figure 1 Materials shown in section construction. That is, as shown in the figure, the material is composed of the skin (A layer), the middle layer (B layer), and the bottom layer (C layer). The skin is made of PVC, polyester fiber fabric or dyed polyester staple fiber non-woven fabric. Fabric, the middle layer uses a synthetic composite of glass non-woven fabric sandwiched polyurethane foam, and the bottom layer uses a non-woven fabric laminated with a film. [0003] The above-mentioned lowerm...
