等に好適な杢糸の接着テープの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a heather suitable for packaging, etc., in which a rubber-based adhesive is attached in the form of a solid substance, thereby preserving the ease of manual tearing of a supporting base material. The present invention relates to a method for manufacturing a yarn adhesive tape.
従来の技術及び課題
天然系繊維からなる織布に代えて合成繊維からなる織布
を用い、これに樹脂のラミネート層を設けて支持基材と
した杢糸の接着テープが提案されている。BACKGROUND OF THE INVENTION A heathered yarn adhesive tape has been proposed in which a woven fabric made of synthetic fibers is used instead of a woven fabric made of natural fibers, and a resin laminate layer is provided thereon as a supporting base material.

昭60−110776号公報、同62−283181号
公報)。Conventionally, as a method for manufacturing such adhesive tapes, a method was known in which a solution-type rubber adhesive made of a solvent was applied to the exposed surface of a woven fabric of a supporting base material and then dried (Japanese Patent Application Laid-open No. 60-110776, 62-283181).

した場合、支持基材が変質して経糸が伸びやすくなり、
手切れ性が太き(低下する問題点があった。However, when the above manufacturing method is applied to a support base material using a woven fabric whose warp threads are fibers made of polyolefin resin, the quality of the support base material changes and the warp threads tend to stretch.
There was a problem that it was difficult to cut by hand.
杢糸の接着テープは梱包用等の包装用途に多用され、手

的要素が大きい難点があった。Therefore, a support base material is used that takes into consideration the reduction in the ease with which it can be cut by hand. In such cases, we aim to stabilize quality throughout the year by taking into account changes in the coating and drying characteristics of the adhesive due to fluctuations in the manufacturing environment, but there are many uncertainties (such as skill factors that depend on experience). However, there was a major drawback.

するものである。That is, in the present invention, a rubber adhesive is substantially applied to the exposed surface of a woven fabric having a laminate layer made of a thermoplastic resin on one side of a woven fabric whose warp is made of fibers made of a polyolefin resin. The present invention provides a method for producing an adhesive tape, which is characterized in that the adhesive tape is attached in the form of a solid substance containing no solvent to the adhesive tape.

着剤を用いた場合、支持基材の変質により手切れ性が大
きく低下したからである。By applying the functional rubber adhesive in the form of a solid substance that does not substantially contain a solvent, it is possible to suppress deterioration of the supporting base material and to prevent a decrease in the ease with which it can be cut by hand. The reason is unknown. H
However, in the experiments of the present inventors, when a film made of the same polyolefin resin was used as a support base material, no deterioration problem occurred, and on the other hand, a water-dispersion type adhesive or a water-dispersion type adhesive instead of a solution type was used. When hot-melt adhesives are used, and when using liquid-type reactive adhesives that enable solvent-free coating by heat-crosslinking monomers or oligomers after coating, the problem may occur due to deterioration of the supporting base material. This is because the ease with which it can be cut by hand has decreased significantly.

じ冷却用として第四ロールが付加されるときもある。The rubber adhesive is attached to the exposed surface of the woven fabric in the supporting base material. In this case, in the present invention, the material is attached in the form of a solid material containing substantially no solvent. Thereby, deterioration of the supporting base material can be suppressed and the ease of manual tearing can be preserved. The attachment method may be determined as appropriate. In the example and line 0, a rubber adhesive such as a solution type or a water dispersion type is coated on a separator and dried to form a solid material that does not substantially contain a solvent. A method in which the layer is transferred to the exposed surface of the woven fabric of the support substrate, or a calendar method in which a solid rubber adhesive is rolled into a sheet using a roll and this is attached to the exposed surface of the woven fabric of the support substrate. Examples include methods. From the viewpoint of manufacturing efficiency, etc., a single calendar type is preferable. In that case, it is important to control the temperature of the rolled sheet-like rubber adhesive at 60 to 80°C at the stage of attaching it to the exposed surface of the woven fabric of the supporting base material using three or more rolls. It is more preferable in terms of preservation. By the way, 3
When using book rolls, such control may include controlling the temperature of the first, second, and third rolls, e.g., about 150°C, about 1
This can be achieved by successively lowering the temperature by 10°C and about 60°C. In the above case, a fourth roll may be added for cooling if necessary.
