example 1

[0072] In the tire of Example 1, ultrasonic welding was used to combine image 3 The Velcro (loop pile material) shown is fixed to the inner surface of the tire, and its welding part is as follows Figure 4 As shown, it is continuously formed along the tire circumferential direction.

example 2

[0073] In the tire of Example 2, the part where the Velcro is fixed in the resin layer is 15% thicker than the other parts, except that it has the same structure as Example 1.

example 3

[0074] In the tire of Example 3, on the back of the Velcro base material, a welding auxiliary film made of the same type of thermoplastic resin as the resin contained in the resin layer was laminated, except for the same structure as Example 1. The thickness of the welding auxiliary film is 50% of the thickness of the resin layer.

Abstract

A pneumatic tire including a resin layer(4) on at least a portion of the tire inside surface, the resin layer being formed from a thermoplastic resin or a thermoplastic elastomer composition in which an elastomer is dispersed in a thermoplastic resin. The pneumatic tire(T) is provided with a fastener(11) including a base material(11a) formed from a thermoplastic resin(11a) and engaging elements(11b) formed on the base material(11a). Additionally, the base material(11a) of the fastener(11) is fixed to the resin layer(4) via fusion bonding.

Description

Technical field [0001] The present invention relates to a pneumatic tire and a method for manufacturing the same. The pneumatic tire is provided with a fastener on the inner surface of the tire for attaching additional objects such as sound-absorbing materials as required. More specifically, it relates to a pneumatic tire even on at least part of the inner surface of the tire. The area is provided with a resin layer, and the pneumatic tire can also be firmly joined to the resin layer, and the manufacturing method thereof. Background technique [0002] A pneumatic tire has been proposed, which is equipped with a Velcro tape on the inner surface of the tire in order to easily install accessories such as sound-absorbing materials (for example, refer to Patent Document 1). In pneumatic tires, in order to reduce the resonance sound generated in the cavity, a sound absorbing material is installed in the cavity. With the above-mentioned pneumatic tire with Velcro, additional materials s...
