Description
This technology is a technology related to a vehicle seat field, specifically, a technique relating to the manufacture of a leather seat cover for a vehicle which is lightweight and has a comfortable ride feeling and wrinkles and shape restoring force.
Natural leather is a tough skin that envelops the body of an animal, removing hairs from leather, and called tanned leather, and these are collectively called leather. If peeled leather is left untreated, it will soon become corroded. However, if it is treated with a suitable emulsion and made into a dew, it does not become rotten even when wetted with water, it does not become hard when dried, and has excellent properties such as heat resistance and water resistance.
Raw materials of the duck are also used in reptile leather, such as mammalian leather, bird skin such as ostrich, and alligator lizard snakes, including sheep sheep sheep. The above-mentioned natural leather corresponds to a high quality material with excellent physical properties, and it is mainly used for products such as furniture, shoes, and bags.
The above-mentioned natural leather is widely used as an interior material such as a sofa or an automobile seat as a furniture. Especially, according to the preference of the consumer who prefers the luxury car recently, the natural leather sheet is widely used as the interior material of the seat for the luxury automobile.
However, when a natural leather is used for a sofa or a car seat, quality problems due to wrinkling of natural leather occur due to use for a long time. In particular, natural leather applied to automobiles has many problems in that wrinkles are generated when the driver gets up by the physical characteristics of natural leather.
Various types of auxiliary sheets have been produced to solve this quality problem, but the fundamental improvement is insufficient. In order to solve the quality problem, rather than improving the physical properties of the natural leather itself, various materials are added to improve the quality. However, there are other types of secondary quality problems.
The natural leather wrinkle prevention technologies developed to improve the natural leather sheet wrinkle problem include a method in which a leather sheet and a polyurethane foam cushioning material are simultaneously sewn to inserting lines to improve wrinkles or a polyurethane foam is heat- But there are many problems in terms of efficiency and efficiency.
Disclosure of Invention Technical Problem [8] The present invention provides a leather seat cover for a vehicle which is light, yet has excellent wrinkle restoring force, minimizes lifting of leather, and can improve ride comfort .
A leather seat cover for a vehicle according to an embodiment of the present invention has a laminated structure in which elastic members and leather fabrics are joined by an adhesive layer. At this time, the elastic member may be formed of a nonwoven fabric formed of polyolefin fibers coated with silicone on the surface and a polyester hollow fiber coated with silicone on the surface or polyolefin fibers coated with silicone on the surface, A polyester hollow fiber coated with silicone and a nonwoven fabric formed of polyester fiber. The adhesive layer is formed by thermocompression bonding of a hot-melt adhesive.
The nonwoven fabric constituting the elastic member preferably comprises 40 to 60% by weight of polyolefin fibers coated with silicone on its surface and 40 to 60% by weight of polyester hollow fibers coated with silicone on the surface. The nonwoven fabric constituting the elastic member includes 30 to 50% by weight of polyolefin fibers coated with silicone on the surface, 30 to 50% by weight of polyester hollow fibers coated with silicone on the surface and 10 to 50% To 30% by weight. The polyolefin fibers forming the nonwoven fabric are preferably made of polypropylene (PP). The polyester hollow fiber or polyester fiber forming the nonwoven fabric is preferably made of polyethylene terephthalate (PET). The polyester fiber forming the nonwoven fabric is preferably a colored fiber.
The elastic member may further comprise a layer of polyurethane foam, preferably combined with a nonwoven fabric and a nonwoven fabric.
The hot-melt adhesive is preferably a hot-melt adhesive in the form of a web or a hot-melt adhesive in the form of a film. When the hot-melt adhesive is in the form of a web or a film, the component is preferably a thermoplastic resin. When the hot-melt adhesive is in the form of a web or a film, the hot-melt adhesive may partially penetrate into the elastic member by thermocompression bonding. The hot-pressing temperature of the hot-melt adhesive is preferably 90 to 140 ° C, and the thermocompression pressure is preferably 1 to 5 bar. When the hot-melt adhesive is in the form of a web or a film made of a thermoplastic resin, the thermocompression bonding temperature is adjusted such that the actual temperature of the hot-melt adhesive reaches a temperature range above the meltability of the thermoplastic resin, .
The leather seat cover for a vehicle according to an embodiment of the present invention can retain the characteristics of the raw material as it is because the changes in physical properties and dimensional changes of the nonwoven fabric and the leather fabric are small during manufacturing through the hot melt bonding process and furthermore the shape stability is excellent.
When the elastic member, which is one component of the leather seat cover for a vehicle according to an embodiment of the present invention, is made of only a nonwoven fabric, it has excellent self-wrinkle restoring force, excellent comfort performance and coverability, The leather lifting phenomenon can be minimized without wrinkles and wrinkles, and the ride comfort performance of the cushion thigh region can be improved.
When the elastic member, which is one component of the leather seat cover for a vehicle according to an embodiment of the present invention, is composed of a nonwoven fabric and a polyurethane foam, the characteristics of the artificial cotton (PET) layer having no repulsive force and elasticity are maintained as much as possible, It is possible to minimize the wrinkle problem that may occur in the packaging process by providing excellent coverage without wrinkles and wrinkles when applied to the curved and curved surfaces.

The softness change, the thickness change and the amount of shrinkage of the raw hide after the hot-melt bonding operation were evaluated for Comparative Examples 2 to 4 and 2 to 4 using the elastic member of COMB type (including polyurethane foam). Table 5 summarizes the results of physical properties evaluation.
Referring to Table 5, it can be seen that the leather seat cover of Examples (2, 3 and 4) has less flexibility change as a whole than the leather seat cover of Comparative Examples (2, 3 and 4) Respectively. In the case of the examples, it was found that the thickness reduction degree in the hot melt bonding process is much smaller than that in the comparative examples.
