The present invention relates to a method of manufacturing a cushion sheet mainly used for vehicles and the like, and particularly to a method of manufacturing a cushion sheet that improves the adhesion between a skin material and a cushion material and simplifies the manufacturing process.

されている。Conventionally, in order to manufacture an integrally molded sheet in which a skin material is attached to the surface of a cushion material as a seat for a vehicle, etc., an adhesive adhesive is applied to the surface of the cushion material formed into a predetermined shape and the skin material is crimped. Either integrate the cushion material and the skin material, or install a heat-sensitive adhesive sheet made from thermoplastic resin between the layers of the skin material and the cushion material, and heat and press the cushion material and the skin material using a heating mold. An integrated manufacturing method is used.

り、座り心地の点でも不具合があった。When using this manufacturing method, the molding equipment is large and
Because the structure is complex, equipment costs are high, and when adhesive adhesives are used, ventilation equipment is required to prevent organic solvents from dispersing into the workplace and the atmosphere, and adhesive application work is required. Due to variations in the bonding process, a large amount of expense was required for process control. Despite this, wrinkles and raised areas tend to occur in the skin material due to poor adhesion, resulting in problems not only in terms of appearance but also in terms of comfort.

り心地の面でも問題は解決されていない。Recently, as a way to solve these problems, a manufacturing method has been developed in which heat-sensitive adhesive sheets made of thermoplastic resin are bonded using a heating mold, but this method has not been able to prevent air pollution caused by organic solvents. However, since the bonding is based on a thermoplastic resin adhesive sheet, it does not have sufficient heat resistance.
In the summer, when the vehicle is parked in direct sunlight, etc.
Peeling occurs between the upholstery material and the cushioning material, and the problem remains unresolved in terms of appearance and comfort.

着性能を保持する。First, a web is formed using fibers such as polyester, which are the raw material for nonwoven fabric, by a method such as a card method, a garnet method, or an airlay method.The web is then fed to a needle punch machine, and the fibers of the web are formed using specially designed needles. By piercing the fibers vertically from a plane and changing some of the fibers that form a two-dimensional random arrangement on a plane into a three-dimensional random arrangement, the entanglement of the fibers is increased and the fibers are mechanically bonded together. . Next, in order to impart strength and abrasion resistance to the product, a water-based heat-sensitive adhesive such as an aqueous resin dispersion is applied to the back side instead of a conventional backing agent, and the product is precoated by heating and drying. This precoating is performed so that a portion of the adhesive is impregnated into the nonwoven fabric skin material, and most of the adhesive remains on the surface of the nonwoven fabric. Specifically, it is ideally applied by adding a foam stabilizer to a heat-sensitive adhesive, continuously foaming it to a size of 3 to 10 times using an oak mixer, and applying this using a doctor knife or roll coater. . Furthermore, coating can also be performed using a print roller. In other words, in the same way as applying a backing agent, which has conventionally been used to strengthen the fiber entanglement of non-woven fabrics, it is possible to apply polyester fibers, nylon or wool fibers to knits, double raschel weave, tricot, jersey, etc. Alternatively, a water-based heat-sensitive adhesive is applied so that a part of the adhesive is impregnated into a skin material made of non-woven fabric or the like, and most of it remains on the surface of the skin material, and the adhesive is precoated by heating and drying. The skin material precoated in this way is stable at normal outside temperatures (below 40° C.), does not exhibit any blocking phenomenon even after being left for one month or more, and maintains sufficient adhesion performance.

This curing agent is, for example, a latent curing agent formed by blocking polyisocyanate with an active hydrogen compound such as phenol. This type of curing agent is stable in the adhesive solution or after drying under normal temperature conditions (below 40°C), but the heat from thermocompression bonding described below causes a rapid curing reaction, causing the adhesive to become heat resistant.

Further, the adhesive of the present invention does not change the viscosity of the liquid even after being left in the making machine at 20° C. for 3 months, and exhibits sufficient foaming properties during use. Furthermore, even when a skin material pre-coated with the adhesive of the present invention is left at 40°C for one month and then thermocompression bonded to an adherend, it maintains sufficient adhesion performance to the extent that the adherend shows breakage in a peel test. Therefore, it shows excellent performance in terms of stability.
