PRESSURE-SENSITIVE ADHESIVE TAPE ROLL FOR CLEANING, APPARATUS FOR PRODUCING PRESSURE-SENSITIVE ADHESIVE TAPE, AND PROCESS FOR PRODUCING THE SAME

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning adhesive tape roll for capturing dust existing on a surface to be cleaned on a dust collecting surface, and more particularly, to a cleaning adhesive tape roll capable of coping with various surfaces to be cleaned such as flooring and a rug.

The adhesive tape roll for cleaning is wound so that the dust collecting surface may face the outer side, and for example, by using a dedicated jig, the dust collecting surface is rolled along the surface to be cleaned, such as the floor, to catch dust on the surface to be cleaned from the dust collecting surface. I can do it.

By the way, in recent years, the bottom surface varies depending on the purpose and place, such as rugs, tatami mats, flooring, cushion floors, etc., but this kind of cleaning adhesive tape roll is rolled along the bottom surface in the rewind direction of the adhesive tape. Since the tape may become a rail and cause the "rail drag phenomenon" (for example, refer to Patent Document 1) to stick to the bottom surface, it was necessary to use the adhesive tape roll separately according to the type of the bottom surface. .

Specifically, a strong adhesive force type with enhanced adhesive strength is used for a surface where dust collecting surfaces such as rugs are hard to stick to, and a weak adhesive type with weak adhesive strength is used for a surface where adhesive tapes such as flooring tend to stick. have.

However, in the case where the user bought and provided the adhesive tape roll (or installation jig) one by one according to the kind of bottom surface, it is troublesome. Then, this applicant proposes the general-purpose adhesive tape roll of patent document 2. As shown in FIG.

The adhesive tape roll is formed on the pressure-sensitive adhesive layer formed on one side of the tape base material at a predetermined interval with a stripping layer having elasticity in a line shape. According to this, the release agent layer is strongly pressed against the surface to be cleaned. When the surface is crushed to increase the contact surface with the pressure-sensitive adhesive layer and is lightly pressed, the release agent layer becomes a spacer and the contact surface with the pressure-sensitive adhesive layer decreases, which can be used both as a carpet and as a flooring. Moreover, since peelability with respect to the back surface (the other surface) of a tape base material improves, the peeling process of the back surface side also becomes unnecessary.

However, in order to avoid fracture, there are points to be improved in terms of formulation selection and productivity of the release agent layer having a high draw strength. That is, in forming a stripping agent layer in a line shape on an adhesive layer, the adhesive layer is formed in the shape which spread | dispersed on one side closely, while running a tape base material conventionally, and then, the peeling agent melt | dissolved on this adhesive layer Was lined up in a thin stripe to form a release agent layer. Therefore, it is necessary to adjust the running speed of a tape base material so that a peeling agent may not be cut off in the middle, and this is making productivity low.

Moreover, since the peeling agent layer is formed on an adhesive layer, it is necessary to add the additive etc. for making the affinity of the interface of an adhesive and a peeling agent good, and the cost becomes high by that much.

In order to make the surface of a tape smooth and to make minimum contact with a back surface, the process etc. which make it pass between rolls and make flat form are also needed. In addition, since there is a distance between the substrate and the discharge port, breakage and spacing become unstable. On the other hand, the ejection in which the application layer of the spacer layer is close to the base material not only improves break prevention, spacing accuracy and productivity, but also adds an additive to improve the affinity for the constituent material between the adhesive layer and the spacer layer. There is no need to mix. Moreover, a material with poor compatibility does not transfer to an opponent, the restriction | limiting of both material selection is alleviated, and it can also suppress cost more cheaply.
