Abstract

PROBLEM TO BE SOLVED: To prevent a synthetic resin from oozing out into a skin material and from being deteriorated in appearance and touch by inserting a barrier material between the skin material having fibrous surface properties and an injection molded synthetic resin backing. SOLUTION: This skin material 1 made of fabric and a barrier material 3 are laminated in advance, and the skin material 1 and the barrier material 3 are placed in molds 4, 5 side by side. Polypropylene is injected into the molds 4, 5 in which the laminated skin material 1 and the barrier material 3 are placed. In this way, a fabric skin material in which the barrier material 3 is inserted between the skin material 1 and the backing 2 is in-molded. Since a polyolefin barrier as the barrier material is inserted between the skin material 1 and the synthetic resin backing 3, the polypropylene which forms the injection molded backing is prevented from oozing out into the skin material 1 so that the deterioration in appearance and touch is prevented.

The protrusion 51 of the die 5 is inserted into the recess 41 of the first die 4, and the synthetic resin forming the substrate 2 is formed in the U-shaped cavity formed. It is ejected from the central portion of 51.

As shown in FIG. 5, since the synthetic resin is injected from below into the U-shaped cavity, the skin material 1 and the barrier material 3 which are laminated are stacked in the first mold 4. Is pressed against the lower wall of the concave portion 41 of
Is filled with polypropylene as a synthetic resin.

After the polypropylene is filled in the capacity, the slide core 6 disposed between the first and second molds 4 and 5 slides rightward and leftward in FIG. The skin material 1 is wound around the lower surface of the base material 2.

As described above, the fabric skin body in which the barrier material 3 is interposed between the skin material 1 and the base material 2 and molded in-mold is taken out from the molds 4 and 5, and As shown in 6, the extra skin material 1 is trimmed.

In the fabric skin body of the present embodiment having the above-mentioned structure, the barrier material 3 of the olefin barrier is inserted between the skin material 1 made of fabric and the base material 2 in which polypropylene is injection-molded. Therefore, the injection-molded polypropylene constituting the base material 2 does not exude into the skin material 1.

The fabric skin of this embodiment is
Since the skin material 1 and the barrier material 3 have a laminated structure, the exudation of polypropylene forming the injection-molded base material 2 is prevented immediately before the skin material 1 and the inside of the skin material 1 is prevented. It is something that cannot be discovered.

Further, in the method for forming a fabric skin according to this embodiment, the skin material 1 made of a fabric and the barrier material 3 are laminated in advance, and the skin material 1 and the barrier material 3 are juxtaposed in a mold. Then, polypropylene is injected into the molds 4 and 5 in which the laminated skin material 1 and the barrier material 3 are juxtaposed, and the barrier material 3 is interposed between the skin material 1 and the base material 2.

Since the molded polypropylene forming the base material 2 does not exude into the skin material 1, the appearance and the tactile sensation are not impaired.

The fabric skin of the present embodiment is
Since the habric as the skin material 1 and the olefin barrier as the barrier material 3 have a laminated structure, the exudation of polypropylene forming the injection-molded base material 2 is prevented immediately before the skin material 1. , The skin material 1
Since it does not exude into the inside, the effect that the appearance and the tactile sensation are not impaired more effectively, and the effect that flocking is unnecessary is achieved.

Further, in the method for molding the fabric skin of the present embodiment, the polypropylene constituting the base material 2 is injected into the molds 4 and 5 in which the skin material 1 and the barrier material 3 are juxtaposed, Since the fabric skin body in which the barrier material 3 is inserted between the skin material 1 and the base material 2 is molded, the number of steps is small and the molding cost can be reduced.

In the method for molding the fabric skin of the present embodiment, the polypropylene constituting the base material 2 is formed in the molds 4 and 5 in which the skin material 1 and the barrier material 3 which are laminated in advance are juxtaposed. Is injected to mold a fabric skin body in which an olefin barrier serving as the barrier material 3 is interposed between the fabric serving as the skin material 1 and the polypropylene serving as the base material 2. Since the exudation of polypropylene that constitutes the base material 2 thus formed is prevented immediately before the skin material 1 and does not exude into the skin material 1, the appearance and touch of the skin body 1 are effectively impaired. It has the effect of preventing it.

Further, in the method for forming the fabric skin body of the present embodiment, the base material is placed in the molds 4 and 5 in which the laminated fabric as the skin material 1 and the olefin barrier as the barrier material 3 are juxtaposed. Injecting polypropylene as 2 to integrally form a fabric skin body in which the olefin barrier is interposed between the fabric and the polypropylene by in-mold molding, and heat-welding the olefin barrier and the polypropylene. This makes it possible to eliminate the need for the conventional bonding step and to achieve the effect of reducing the thickness of the fabric skin.

Further, in the method for forming a fabric skin according to the present embodiment, the polypropylene is injected into the molds 4 and 5 in which the laminated fabric and the olefin barrier are juxtaposed to form the fabric skin. Since it is integrally molded by in-mold molding, the olefin barrier and the polypropylene are heat-welded, so that the reliability of the adhesion performance of the fabric skin is improved.

Further, in the method for molding the fabric skin of the present embodiment, the polypropylene is injected into the molds 4 and 5 and the fabric skin is integrally molded by in-mold molding. Since the fabric, the laminated olefin barrier, and the polypropylene are heat-welded, it is possible to reduce the number of man-hours by attaching the base material to the front surface and the back surface of the base material, eliminating the need for an operator to attach the base material. This has the effect of significantly reducing the amount.

In the method for molding the fabric skin of the present embodiment, the polypropylene of the base material 2 is filled in the capacity, and then disposed between the first and second molds 4 and 5. By sliding the slide core 6 to the right and left in the drawing, the skin material 1 is wound on the lower surface of the base material 2, so that it is not necessary for the operator to wind it on the lower surface of the base material 2 as in the conventional case. Thus, the effect of reducing the number of work steps is obtained.

The above-described embodiments are merely examples for explanation, and the present invention is not limited thereto, and those skilled in the art can recognize from the claims, the detailed description of the invention and the description of the drawings.
