In particular, in the former case, in order to increase the tensile strength of the pressure-sensitive adhesive tape, it is necessary to use high-strength single thread of each thread used in plain weave.

る。However, this time, since the strength of each single yarn is great in order to cut it to an appropriate length at the time of use, a considerable force is required to tear it by hand, and breaking from a desired position is particularly difficult. A base fabric for a pressure-sensitive adhesive tape, which is a plain weave and uses warp yarns weaker than weft yarns, is described in JP-A-4-117476, page 2, lower left column, lines 2 to 5. However, since the warp yarns are continuous, stress concentration is unlikely to occur in a part at the time of cutting, and it is necessary to considerably weaken the warp yarns in order to facilitate cutting, resulting in insufficient strength as a whole.

巻いて製品とする。The reinforcing cloth for pressure-sensitive adhesive tape according to the first aspect of the present invention is a knitted cloth used when manufacturing a pressure-sensitive adhesive tape, and a synthetic resin emulsion is applied by laminating an extremely thin synthetic resin film on the lower surface thereof. A synthetic resin layer is formed on one side by gelling to make a knitted fabric, and a pressure-sensitive adhesive is applied on the other side, and an appropriate width, for example, 4c

これら編み糸の絶体強度の大小に影響はない。When this adhesive tape is used, a roll-shaped tape is peeled off by a required dimension, and when force is applied so as to tear it in the transverse direction by hand, strong knitting is performed at a part of one side edge of the adhesive tape. The yarn and the weak knitting yarn are pulled so as to be separated from each other while being hooked on each other at the loop and the sinker portion, and both of these knitting yarns are pulled in the state of being bent at a steep angle, which is weak. If one of the knitting yarns always causes so-called knot cutting, and the weak yarn is cut at one end of the adhesive tape, then stress concentration will occur in the engaging part of the next well of this course, and similarly knot cutting will occur. The adhesive tape has a function of being cut in a straight line in the transverse direction of the adhesive tape along the weak yarn course. This action always occurs if there is a difference in strength between strong and weak threads,
There is no effect on the absolute strength of these knitting yarns.

The difference in strength is obvious, and the above-mentioned knot cutting action surely occurs in the weak knitting yarn portion, and the strength of the entire tape is sufficient.

起こらない。According to a fourth aspect of the present invention, there is provided an adhesive tape using the reinforcing knitted fabric according to the first aspect,
In the present invention, since the reinforcing knitted fabric has the above-mentioned structure, when it is attempted to rupture it by hand in the transverse direction, the strong yarn and the weak yarn cause a knotting phenomenon, and the weak yarn portion always has a straightness in the transverse direction. The adhesive tape is cut into letters, and the phenomenon that the adhesive tape has a narrow width and is not twisted or twisted unlike a knitted fabric made of knitting yarns having the same strength in each course does not occur.

れば、この引張強度に耐えるテープとなる。In the invention of claim 5, since the reinforcing tape is an adhesive tape in which the strength ratio of strong and weak knitting yarns is 5: 2 to 4: 3, the difference in tensile strength between strong and weak knitting yarns is obtained. When the adhesive tape is fractured in the transverse direction, it is more accurately fractured from the weak yarn portion, and the strength difference between the strength and the weakness is 5: 2 to 4: 3.
Therefore, if the strength of the weak yarn is set to the target tensile strength, the tape can withstand this tensile strength.

作用をなす。According to the sixth aspect of the present invention, since the pressure-sensitive adhesive tape uses the reinforcing knitted fabric according to the third aspect of the present invention as the reinforcing knitted fabric, it hardly expands or contracts in the longitudinal direction and the transverse direction, and particularly the transverse direction. With respect to the direction, since insertion yarns having almost no elasticity are inserted for every 1 to 3 courses, the yarns are hardly stretched and endure the tensile force in the width direction. Further, since the above-mentioned insertion yarn is inserted in the width direction, it has a function of breaking in the transverse direction like the adhesive tape of the other invention described above.

The difference is that the insertion yarn 12 is inserted every other course, and in the example shown in the figure, it is inserted into the strong knitting yarn portion 10. The difference from Example 3 is that the insertion yarn 12 is inserted in the middle part of the stitch of the knitting yarn 10 where the insertion position is strong. The insertion yarn 12 is not particularly limited, but it is preferable that the insertion yarn 12 has almost no elasticity, and synthetic resin fibers or other chemical fibers or natural fibers may be used. The denier number may be the same as that of the strong or weak knitting yarn 10 or 11.
