Abstract

PROBLEM TO BE SOLVED: To prevent contamination of a clean room even if a paper tube is brought into the room by using dust-free paper having specific number or blow of particles each having a specific particle size or below per one cubic foot for the tube. SOLUTION: The dust-free paper tube is set to 1,700 or below pieces of of particles each having a particle size of 0.3 μm or above per one cubic foot (0.02832 m2) by using dust-free paper of natural pulp made of wood fiber, bast fiber, fine Japanese paper fiber or the like, synthetic fiber such as nylon fiber, rayon fiber or the like, and synthetic pulp represented by fibrillated polyethylene. Thus, even if the tube is brought into a clean room, a contamination of the room can be prevented. When an outermost surface is spirally wound up so as to be partly superposed and then a protrusion formed by the superposition is cut to manufacture the tube, a soft film or the like can be wound on the tube without causing winding mark of the tape-like paper.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow paper tube for winding a long object such as paper or film, and more particularly, to a non-dusting paper tube which does not contaminate a clean room even when brought into a clean room. The present invention relates to a tube and a paper tube in which a film wound around the tube does not have a spiral wound mark at the time of manufacturing the tube.

2. Description of the Related Art Conventionally, a paper tube for winding a long object such as paper or film has been manufactured by spirally winding paper cut into a tape shape while adhering with a paste. However, these paper tubes are manufactured without planning to be brought into a clean room.
Therefore, the conventional film product wound on a paper tube has a drawback that it cannot be carried into the clean room together with the paper tube because of the generation of dust from the paper tube. Further, when a soft film or the like is wound around a paper tube, there is a disadvantage that the film or the like has a trace of winding derived from the tubular winding at the time of manufacturing the paper tube.

SUMMARY OF THE INVENTION Accordingly, a first object of the present invention is to provide a non-dusting paper tube which does not contaminate the clean room even when it is carried into the clean room. A second object of the present invention is to provide a non-dusting material that, when a soft film or the like is wound, does not have a spiral winding mark of a paper tube on the film or the like and can be directly carried into a clean room.

In the production of the paper tube of the present invention, the paper forming the paper tube is cut into a tape shape, and this is wound into a tubular shape while adhering it with a glue as is known. In this case, although a spiral recess is formed in the outermost layer of the paper tube, it can be used, for example, as a paper tube for a long object of the dust-free paper. However,
As shown in FIG. 1, the outermost layer portion is partially

A resin liquid is applied to the surface of the outermost layer portion and dried to cover the entire surface of the surface from which the protrusions 2 have been removed or the entire surface is covered with a resin layer, or a heat-shrinkable film tube is placed over the surface to heat the resin. Preferably, it is treated and covered with a heat shrink film. When a long paper tube is used, it is cut into a desired length suitable for the width of a long object such as dust-free paper or a film wound around the paper tube. The coating with the resin layer or the heat-shrinkable film may be performed after the wound paper tube is cut into a desired length.

The sizing agent for producing the paper tube can be appropriately selected from sizing agents conventionally used for paper tubes, such as starch-based, vinyl acetate-based and polyvinyl alcohol-based sizing agents. When the paper tube of the present invention has a resin layer on the outermost layer surface, and when a resin liquid is applied to the surface of the paper tube to form the resin layer, the resin liquid is used for dust-free paper. The same resin as the binder can be appropriately used. The thickness of the resin layer after coating and drying is not particularly limited, but is usually 5 to 50 μm.

In the present invention, the resin layer provided on the outermost layer of the paper tube is preferably a film, particularly a heat-shrinkable film. The heat-shrinkable film can be appropriately selected from known heat-shrinkable plastic films. Typical heat-shrinkable films used in the present invention include vinyl chloride, polyester, polystyrene,
Alternatively, a polyolefin-based film such as polyethylene or polypropylene may be mentioned, but from the viewpoint of disposal after use, a non-vinyl chloride-based film is preferred, and a polyester-based or polyolefin-based resin is particularly preferred.

The thickness of the heat-shrinkable film coated in this manner varies depending on the hardness of the film. However, when a soft film is wound on a paper tube, the thickness of the film does not show a spiral winding mark on the paper tube. It is preferred to minimize it, usually 20 to 100 μm. When the paper tube (see FIG. 1) after removing and smoothing the convex portion 2 caused by the winding and overlapping so as to partially overlap the outermost layer portion is used, the thickness of the heat shrinkable film is usually 5 2020 μm is sufficient.
