If it is loosened, the tensile stress becomes weaker as it is loosened, and the elongation becomes smaller.When the tensile elongation disappears, the tensile stress disappears and the state before pulling is restored. In addition, it shows almost the same characteristics as the stretch elasticity due to tension tension and release of slack after the next time.

Products such as menstrual napkins, panty liners, masks, underwear such as pants and trunks, clothing, etc. do not give a feeling of tightness of wearing, and in order to achieve the intended purpose, the part that requires tightening is strong, It is desirable that the parts are weak or hardly tightened. In the case of a paper diaper, it is mainly the abdomen and the back that need to prevent urine from leaking around the waist. Therefore, the abdomen and the back are strongly tightened, while the body side is weakly tightened, and the legs are not tightened. It is mainly the front and back parts of the crotch inside the leg that need to prevent leakage of urine, and therefore the front and back parts of the crotch inside the leg are strongly tightened, while the parts other than the front and back parts of the crotch inside the leg are not tightened. When the pressure is weakened, it is possible to expect that it is possible to prevent stuffiness of the crotch, buttocks, abdomen and back without causing a feeling of tightness and allowing air to smoothly flow in and out of the diaper. The same can be expected in the case of underwear such as pants and trunks and clothes.

The expansion and contraction elasticity given by various methods also becomes the expansion and contraction elasticity conforming to the elastic rubber product.

However, since the above-mentioned products are small or the elastic rubber products used are small, there is a problem in that a wide variety of expansion and contraction elasticity cannot be achieved, and the above-described device cannot be adopted.

It was found that when stretched by hanging, the stretched elasticity of initial tensile stress and elongation is impaired and changed in the pulled portion. It is difficult to specify the detailed behavior of the fibrous additives, but before applying a load above a certain level, the fibrous additives are entangled with each other in the rubber after vulcanization, or are bonded to the rubber, melt, and become large. While it has a tensile stress and a small expansion and contraction, when a load of a certain level or more is applied, the fibrous additive shifts in the rubber, tears, peels off, falls out, becomes entangled, or stretches out. By doing so, it is considered that the influence of the fibrous additive is impaired or reduced to change the tensile stress and the elongation.

る。Generally, the elastic rubber product is used by being stretched and pulled, but the main feature of the present invention is that the fibrous additive affects the stretchable physical properties of the elastic rubber product and impairs or reduces the influence thereof. The point is that I was allowed to do so. Such an elastic rubber product can be manufactured in a state in which the entire tensile stress is high and the expansion and contraction are small, and a necessary portion can be subjected to a tensile stress of a predetermined level or more to impair or reduce the influence of the fibrous additive. That is, the necessary part has high tensile strength, the other part has low tensile strength, the necessary part has large shrinkage, the other part has small shrinkage, and the necessary part has large elongation. The portion has a small elongation, and can give a wide variety of stretch elasticity.

It is also possible to appropriately carry out the above-mentioned stretching treatment in which the non-stretched portion is partially or partially changed to the stretched portion. The tensile strength of the non-stretched portion and the stretched portion depends on the rubber composition, the amount and type of the compounding agent / filler, the compounded rubber, the manufacturing conditions, the amount and type of the fibrous additive, the fibrous state of the stretched portion or the non-stretched portion. Although it changes depending on the behavior of the additive, considering the application of the elastic rubber product, the extension part has a stress physical property of tensile strength that is almost equal to the stretch elastic property of the tensile stress physical property generated after vulcanizing the rubber composition before mixing. It is preferable that the elastic elasticity is.

When oriented in the rolling direction and the degree of orientation increases, crystallization progresses, and mechanical anisotropy that causes a difference in tensile strength and elongation between the rolling direction and the direction orthogonal thereto, that is, a so-called grain phenomenon occurs. When the pressure during rolling is high, the temperature of the bank rubber is low, the thickness is thin, the rolling is repeated or pulled in the same direction, the grain is strongly expressed. This grain phenomenon appears remarkably in the unvulcanized one, and is mostly removed by the vulcanization. The same happens for extrusion and extraction. Further, even if the rolled, extruded and extracted product is molded into a die, a grain phenomenon can be obtained.

Further, by utilizing the grain phenomenon, it is possible to impart more varied elastic elasticity. For example,
In the case of a rubber sheet, in order to strengthen the grain phenomenon, it is effective to lower the roll temperature, lower the temperature of the bank rubber, strengthen the take-up tension of the rubber sheet, and cool quickly so that distortion remains.

み、平均幅の誤差は製造工程における公差である。From the test results, when nylon short fibers were added, there was a difference between the characteristic curve for load at the time of pulling and the characteristic curve for load return at the time of releasing the tension for the first pulling, but after the second pulling There is no difference in the history of load going and load returning, and as the amount of short nylon fiber added is increased, there is a difference in the characteristic curves of load going and load returning after the first and second times, and the elastic elasticity changes. I know that However, it can be seen that the characteristic curves of load going and returning after the second time are almost the same in Examples 1 to 4 regardless of the amount of the short nylon fiber added. The errors in the average thickness and the average width of the thread-shaped elastic rubber products of Comparative Example 1 and Examples 1 to 4 are tolerances in the manufacturing process.
