The inner coat 3 of which thickness is about 0.35 mm is coated on the outside surface of the interior cable 1. The surface diameter of the inner coat three is 3.7 mm. The control cable of the present invention contains a conduit having flexibility, the inside surface of which being set up with a liner and an internal cable having an inside coat, and the inner cable is inserted into the conduit so that the inner cable freely slides within the conduit as mentioned above. Among the many above-mentioned thermoplastic resins, polybutylene terephthalate having a melt index of 0.1 to 5 g/10 minutes will be significantly preferably used because the change of load effectivity is small when the control cable is used for a long period of time. As an example, a method comprising ading the organopolysiloxane having an extremely-high viscosity and the organopolysiloxane having a decrease viscosity separately to the thermoplastic resin whereas heating and kneading the thermoplastic resin and uniformly dispersing them, a technique comprising including the organopolysiloxane, which is beforehand ready by mixing the organopolysiloxane having an extremely-high viscosity and the organopolysiloxane having a lower viscosity in a prescribed proportion, to the melted thermoplastic resin and uniformly dispersing them, and the like could be exemplified.
In the present invention, since the organopolysiloxane having an ultra-excessive viscosity and the organopolysiloxane having a decrease viscosity are dispersively contained in the thermoplastic resin used within the above-mentioned liner, it's after all that there is no such thing as a necessity to use a lubricant between the interspace of the conduit and the inside cable, and a superb operate that the sliding operation of the conduit and the inside cable could be easily carried out for a protracted period of time, is exhibited. The organopolysiloxane comprising the organopolysiloxane having an ultra-excessive viscosity and the organopolysiloxane having a lower viscosity is dispersively contained in the thermoplastic resin in order that the content of the organopolysiloxane is thirteen to 20% by weight. When the kinematic viscosity exceeds 10000 cSt, the organopolysiloxane doesn't bleed out from the thermoplastic resin sufficiently, and the load efficiency is lowered. The representative examples of the organopolysiloxane having a lower viscosity are, as an illustration, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like.
The standard examples are, as an example, dimethylpolysiloxane, methylalkylpolysiloxane, methylphenylpolysiloxane, methylaminoalkylpolysiloxane, methylfluoroalkylpolysiloxane, and the like. As a material for the inside coat, for instance, Teflon, 11-nylon and the like are used. Among them, dimethylpolysiloxane is especially preferable from the viewpoint of lubricationability between the thermoplastic resin of the liner and that of the interior coat, thermal resistance, cost, and the like. The quantities of the organopolysiloxane having an extremely-excessive viscosity and the organopolysiloxane having a lower viscosity contained within the thermoplastic resin of the above-mentioned liner are adjusted in order that the organopolysiloxane is composed of 45 to 85% by weight of the organopolysiloxane having an extremely-excessive viscosity and fifty five to 15% by weight of the organopolysiloxane having a lower viscosity. Accordingly, an organopolysiloxane having an ultra-high viscosity and an organopolysiloxane having a decrease viscosity are used in the present invention so as to enhance extruding stability during producing a liner and to sufficiently launch these organopolysiloxanes on the surface of the resin sufficiently. The control cable has been conventionally used so as to function a transmission utilized in cars, autobicycles, bicycles and the like, a brake, a clutch, a speedmeter, and the like. In order to enhance the load effectivity of a control cable without a lubricant, an organopolysiloxane is contained in a resin for a liner or an interior coat, and the organopolysiloxane extides from on the floor of the resin.
When the content of the organopolysiloxane is less than 13% by weight, the load effectivity is lowered when the management cable is used for a long time frame. When the content of the organopolysiloxane having an extremely-excessive viscosity is more than 85% by weight and the content of the organopolysiloxane having a lower viscosity is much less that 15% by weight, the consequences do not differ much from the effects when the organopolysiloxane having an extremely-excessive viscosity is used solely, and the improvement of load efficiency is little. However, when the viscosity of the organopolysiloxane is just too excessive, the amount of the organopolysiloxane which is extided from the surface of the resin is little, and according the load effectivity and durability of the control cable can't be improved sufficiently. Also, the sturdiness of the above-talked about control cable largely depends upon the lubricant. Also, a artificial resin coating (hereinafter known as inside coat) is ready on the outer surroundings of the interior cable. However, there are a number of problems, in the management cable by which a lubricant is used, such as issue of operation for coating as a result of dispersion of the load efficiency of merchandise is caused by the unevenness of a coating, rubbishes and dusts are easily adhered to the lubricant when applying the lubricant to the control cable, and drip and the like are generated.
