れまでに採用されたことは殆ど無かった。Conventionally, various types of non-woven skin materials for automobile interior materials have been studied depending on the parts used, such as trunk interior materials, ceiling skin materials, door trim ornaments and the like. However, if it is used in parts where particularly high abrasion resistance and excellent design properties are required, for example, skin materials such as car seats and door trim ornaments,
Since non-woven fabrics cannot meet these conditions, they have hardly ever been employed.

内装材用表皮材を提供するものである。[0004] In order to increase the abrasion resistance of the nonwoven fabric, it is necessary to increase the degree of fiber entanglement, the amount of resin adhered during resin processing, the mixing ratio of binder fibers, and the like. This is because not only the soft surface feel that the nonwoven fabric originally has is lost, but also the molding followability is lost. The present invention solves these problems and provides a car interior made of non-woven fabric which not only satisfies abrasion resistance and has not only the surface feel of a fabric but also the molding followability as required. It is intended to provide a skin material.

材用表皮材を得ることに成功したものである。According to the present invention, various experiments are repeated to obtain a nonwoven fabric having improved abrasion resistance and moldability without impairing the surface fabric feeling of the needle punched nonwoven fabric. As a result, the amount of resin in the resin processing applied to the needled web layer is suppressed to a small amount within a certain range, and then the resin processing is performed. Then, stitch bond processing is performed, or the binder fiber is fixed instead of the resin processing of the web layer. After blending at the following ratio and needling, stitch bond processing was performed to easily obtain a desired skin material for an automobile interior material.

Skin material is obtained. Conversely, if a yarn with low elasticity is used, it can be used in a portion where the elasticity of the car sheet material is low, so that it is possible to obtain a skin material for automotive interior materials having a very wide application range. .

On the other hand, stitch bond processing is performed for the purpose of complementing wear resistance and imparting designability. If the thread used for stitch bond processing does not require exceptional molding followability such as car sheet material, it is sufficient to use an extremely ordinary filament thread or processed thread, especially when suppressing elongation. A low melting point yarn may be used. However, when performing deep drawing such as molding door trim skin material, by using stretchable yarn such as false twisted crimped yarn or spandex yarn, not only improves wear resistance, but also improves the design effect. Can be increased, and molding followability can be provided.

The yarn used for the stitch bond processing is a false twist crimp processing It is more effective to use a stretchable yarn such as a yarn or a spandex yarn, and it is possible to improve the molding followability by changing the stitch bond pattern or the driving density of the yarn.

である。On the other hand, as another structure of the present invention, low elongation at a constant load elongation is required, and a soft surface feel and a high level of abrasion resistance are required, such as a skin material for a car seat. In this case, a web made of one or a mixture of two or more selected from synthetic fibers such as polyester fibers, polyamide fibers, rayon, polyvinyl chloride, acrylic, polypropylene, and polyethylene is used.
0 to 300 g / m 2 ), 2 to 30%, more preferably 5 to 10% by weight of a simple substance such as polyester, polypropylene, polyethylene, polyamide, ethylene-vinyl acetate copolymer, or a conjugate thereof. After a binder fiber such as a gate fiber is mixed and needling, stitch bond processing is performed. The yarn used for the stitch bond processing may be a normal filament yarn or a processed yarn, but it is effective to use a low-melting-point yarn particularly when the elongation is to be suppressed. To further improve the effect, it is also effective to change the pattern of the stitch bond or the driving density of the yarn. In addition, the length may be a length in which a binder fiber is blended, but it is of course possible to use a binder resin in combination.

に実用的では無くなってくる。In order to ensure the abrasion resistance of the abrasion resistant automobile interior skin material of the present invention, in the case of the resin processing method, if the weight ratio of the binder is less than 2%, it is necessary to use the binder in combination with the binder fiber. In the case of non-woven fabrics, various physical properties (such as abrasion resistance and texture) due to insufficient adhesion between fibers
The problem is big. On the other hand, if it exceeds 10%, the moldability gradually decreases, and if it exceeds 20%, the texture of the surface is impaired, and it becomes impractical.

In some cases, a practical sheet cannot be obtained. The compounding ratio is 30
%, Only a hard texture is obtained, and other physical properties such as tearing are remarkably reduced, so that a preferable skin material cannot be obtained.

も良い。The wear-resistant automotive interior skin material according to the present invention is prepared by blending a certain amount of binder fiber into a needle-punched nonwoven fabric or performing resin processing using a binder resin in order to increase the surface wear resistance. It was obtained by performing stitch bond processing. The binder fiber or binder resin used here is not intended to improve the wear resistance, but also has an effect of obtaining the surface texture (soft feel) of the obtained sheet. In addition, stitch bond processing is not a length that improves abrasion resistance without impairing the texture, but it is possible to improve the followability of molding processing by changing the type of thread used, or to suppress the degree of elongation on the contrary. is there. At this time, the effect can be further enhanced by changing the pattern of the stitch bond processing and the driving density of the yarn. Various additives may be added to the binder resin as needed, such as adding a water repellent to prevent contamination when a liquid such as coffee is spilled.

て、破断時の伸び率を測定して平均値を求める。The measurement of physical properties in the present invention was carried out by the following methods. (20% modulus) Five test pieces having a width of 5 cm and a length of 20 cm were sampled, and the tensile speed was 2 according to JIS L1068.
It is pulled at 0 cm / min and the stress (unit: Kg) when the elongation is 20% is measured, and the average value is obtained. (Abrasion resistance) By Taber type rotary abressa,
A load of 250 g is applied to the worn wheel CS-10 so as to come into contact with the test piece, and after the sample is rotated 500 times at a speed of 60 rpm, the surface state of the test piece is measured. Judgment standard No change. Grade 4 A slight change is observed. Class 3 changes are clearly observed. Level 2 The change is remarkable. Class 1 The change is remarkable. (Moldability) The interior surface of the nonwoven fabric is formed by laminating a nonwoven fabric surface through a polyamide film with a woody resin board used as a base material for a door material, and integrally heating and molding using a mold. At this time, check the presence or absence of floating between the substrate and the nonwoven fabric,
Those with no floating are judged as good, and those with floating are judged as bad. (Elongation%) 5 specimens 5cm wide and 20cm long were sampled,
According to JIS L 1068, the film is pulled at a pulling rate of 20 / cm / min, and the elongation at break is measured to obtain an average value.

性自動車内装表皮材を得ることに成功したものである。According to the present invention, a needle-punched nonwoven fabric is blended with a binder fiber or a binder resin in a certain range and processed so as to secure softness of the texture and a soft surface feel, and further perform stitch bond processing. Conventionally, if you try to secure the softness of the texture (soft surface feel), the abrasion resistance will decrease, and if you try to improve the abrasion resistance, the softness of the texture and the soft surface feel will be sacrificed. In addition to solving the inevitable problems of the physical properties of the nonwoven fabric, it has succeeded in obtaining an excellent wear-resistant automotive interior skin material that can be formed.
