Abstract

PURPOSE:To increase the adhesion between a plate and the carpet by extrusion- molding the plate for reinforcement which is fixed onto the carpet and forming a nappy recessed part on the surface of the plate during the time when the remaining heat in the molding is left. CONSTITUTION:In a floor carpet 7, a backing layer 8 and a felt layer 9 are laminated in succession onto a carpet 6, and a plate 1 made of thermoplastic resin is attached onto the backing layer 8. In this case, the plate 1 is formed by extruding thermoplastic resin 10 from a T-die 2 and compressing said resin by a pair of rolls 3 and 4, and the resin is molded. A pair of rolls are constituted of the rubber roll 3 and the roll 4 having a recessed part, and a nappy recessed part 5 is formed on the surface of the plate 1 by allowing the plate 1 to pass through a pair of rolls 3 and 4 during the time when the remaining heat in the extrusion molding is left. Thus, the adhesion strength between the plate 1 and the carpet 6 is increased.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method of manufacturing a floor carpet to be laid on the floor of an automobile. In particular, the present invention relates to a method of manufacturing a floor carpet using a thermoplastic resin plate which is pressed with a roll while still hot during sheet extrusion molding to form an uneven portion on one side and fluff it.

In general, floor carpets are required to have a rigidity greater than that of the interior of an automobile in order to prevent deformation after being installed in the interior of an automobile. In particular, rising parts such as side parts, dash parts, rear parts, and tunnel parts of the floor are required to have greater rigidity than the contact parts.

This is a very difficult requirement when considering the structure of the floor carpet. In other words, during molding, the rising part is stretched compared to the general part (the rising part has a deeper drawing than the general part), so the backing layer becomes thinner and the rigidity becomes smaller. Therefore, in order to prevent the stiffness of the rising part from decreasing, conventionally, parts with low rigidity were reinforced with thermoplastic resin plates laminated with nonwoven fabric.

That is, the plate is set in advance on the mold surface of the reinforced area, and a carpet with a softened and melted thermoplastic resin backing layer is placed on it and pressed, thereby molding the carpet and molding the thermoplastic resin plate. It was stuck to the reinforced part. The nonwoven fabric improves adhesion to the thermoplastic resin in a softened and molten state, and is laminated in advance on the surface of the thermoplastic resin plate using adhesives, tacker fastening, sewing with a sewing machine, or the like.

However, since the nonwoven fabric is fixed to the thermoplastic resin plate using adhesive, tacker fastening, sewing machine sewing, etc., there is a problem in that the number of manufacturing steps increases.

Furthermore, since the nonwoven fabric was in the form of a sheet, the surface was uniform and there was little fuzz. Therefore, unless the basis weight of the nonwoven fabric is increased, good adhesion to the thermoplastic resin of the backing layer cannot be obtained during carpet molding. Moreover, non-woven fabrics are expensive and are a factor in increasing costs.

An object of the present invention is to overcome the above-mentioned problems and provide a method for manufacturing a floor carpet that can reduce material costs and shorten the manufacturing process, while also providing good adhesion to the thermoplastic resin of the backing layer.

The means of the present invention for solving the problems is a method of manufacturing a floor carpet, which is reinforced by fixing a thermoplastic resin plate to the back surface of the backing layer corresponding to the area with large irregularities of the floor carpet at the same time as the carpet is molded. In , the thermoplastic resin plate was sheet extrusion molded, and the surface was fluffed by pressing it with a pair of rolls with one roll having a recess while the sheet was still heated during extrusion molding. .

〔作  用〕[For production]

シート押出成形時の余熱がある間にロールで押圧するの

The thermoplastic resin plate is soft because it is pressed with rolls while there is residual heat during sheet extrusion molding.

Therefore, by pressing with a roll, the recesses formed in the roll are formed on the thermoplastic resin plate, resulting in a fluffy state.

In addition, unlike the nonwoven laminated surface, it is fluffy, so during carpet molding, the anchoring effect with the thermoplastic resin of the backing layer of the carpet increases, and the adhesive strength with the carpet improves.

Moreover, since the recesses are formed in the thermoplastic resin plate while there is residual heat during extrusion molding, it can be performed in a series of steps. Therefore, the manufacturing process can be shortened and the process can be simplified.

Figure 1 shows a thermoplastic resin plate 1 used in the present invention.
It is a figure showing the manufacturing process of. In this figure, 2 is an extruder such as a T-die, 3 is a rubber roll, and 4 is a roll with recesses. A thermoplastic resin lO such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, etc. is extruded into the T-die 2 in the form of a sheet. The extrusion temperature is a commonly used extrusion temperature for each resin, for example, 2 for polypropylene resin.
The range of 10 to 300″C is normal, especially 250 to 29
The extruded thermoplastic resin plate 1, preferably in the range of 0'C, is pressed by a pair of rolls. The pair of rolls consists of a rubber roll 3 and a recessed roll 4.
By passing the extruded thermoplastic resin plate l through the pair of rolls while it is still hot, it is possible to form the fluffy recesses 5 on the surface. At this time, if the temperature of the recessed roll 4 is set to a temperature relatively close to the extrusion temperature of the resin, a lot of fluff can be formed on the sheet surface due to the stringing phenomenon of the resin.

The thermoplastic resin plate 1 is adhered to the back surface of the backing layer of the floor carpet in areas with large irregularities, such as the rising parts on both sides of the floor or the bulge in the center. The surface of the thermoplastic resin plate 1 is fluffed, and the thermoplastic resin of the backing layer 8 of the carpet 7 penetrates into the fluffed surface, thereby providing good adhesion. The thermoplastic resin plate 1 is made of thermoplastic resin, such as polypropylene, polyethylene, ABS, vinyl chloride, etc.
