- the hose of Example 1 comprising the materials described in Table 1 was manufactured such that the inner rubber layer is first extruded on the mandrel, the first braided layer is then formed on the outer periphery of the inner rubber layer by braiding, the middle rubber layer is then formed on the outer periphery of the first braided layer, the second braided layer is then formed on the outer periphery of the middle rubber layer by braiding, the outer rubber layer is then formed on the outer periphery of the second braided layer by extrusion, and the vulcanization is finally conducted to obtain the hose.
- the hoses of Comparative Example 1 to 3 comprising the materials described in Table 1 were manufactured by the same process as Example 1.
- the examination of the durability was carried out by the following method by using a bending testing machine (model number: V270-2) from Sum Electro Mechanics Co., LTD.
- a brake fluid JIS K2233
- JIS K2233 JIS K2233
- FIG. 3 fixing one end of the hose, bending strokes of ⁇ 40 mm at a frequency of 1.66 Hz are applied to the other end of the hose.
- the number of bending strokes until the hose is damaged is defined as the number of durability.
- the hose was attached at the time of the examination in a layout to cause simultaneously the bending and twisting of the hose.
- the elongation rate of the yarn at a load of 10 N is an index assuming that a hose is pressurized at 10 MPa, and multiple wound yarns of 1330 dtex in fineness were used for the measurement thereof.
- Example 1 and Comparative Example 2 that a reduction in the total fineness of the second braided layer causes a reduction in the expansion quantity, and by comparing Comparative Example 1 with Comparative Example 3 that a low elongation rate of a yarn at a load of 10 N causes a low expansion quantity, but results in a low durability.
- Example 1 In comparing Example 1 and Comparative Examples 1 to 3 shown in Table 1, it is proved that the tensile strength tends to increase when the elongation rate of a yarn at a load of 10 N is small and the total fineness is large.
- the hose of Example 1 as an embodiment of this invention is such a hose that can controls the reduction of the tensile strength to a minimum in spite of the reduction of the total fineness, and has the ultralow expansion quantity performance not more than 0.090 ml/305 mm (0.087 ml/305 mm in Example 1), and keeps the durability not less than 600,000 times (700,000 times in Example 1).
- this invention can realize the ultralow expansion quantity performance by using the three-over, three-under braid pattern to the braiding method of the first braiding layer. Besides, this invention can achieve the further low expansion quantity performance and minimize the reduction of the tensile strength in spite of the reduction of the total fineness by using the vinylon fibers manufactured by the wet process to the second braided layer having only a small influence on the durability and by reducing the median diameter of the braided layer by reducing the total fineness.
