- the nonwoven fabric 2 is pressurized by the shaping
- the “predetermined temperature” is a temperature at which the nonwoven fabric 2 can be heated to a temperature within the “first temperature zone”.
- the “predetermined temperature” is a temperature within the “first temperature zone” or a temperature higher than that.
- the “predetermined time” is as follows. Of the nonwoven fabric 2, the portion in contact with the jig 6 and the portion in the vicinity thereof (that is, the portion that becomes the surface layer portion of the exterior material 11a) is the time to reach the temperature within the first temperature zone. 12 and a portion in contact with a predetermined portion of the bundle of electric wires 12 and a portion in the vicinity thereof (that is, a portion that becomes the central portion of the exterior material 11a) are times when the temperature does not reach the temperature within the first temperature zone. .
- the cooling method is not particularly limited. For example, a method of storing in a refrigerator, a method of spraying a normal or low temperature gas, a method of leaving in a normal temperature, and the like can be applied.
- the jig 6 is formed of a material having high thermal conductivity and has a configuration that easily transfers heat between the inside and the outside. For this reason, the heat which the molded exterior material 11a has is rapidly dissipated outside through the jig 6. Further, if the jig 6 is made of a metal plate or the like and is formed by sheet metal processing or the like (that is, if the mass is small), the amount of heat storage is small. The descent begins. For this reason, the molded exterior material 11 a is not heated by the jig 6 after being removed from the mold 5. According to such a structure, it can prevent that the shape
- the exterior material 11a having the first portion 111a, the second portion 112a, and the third portion 113a is formed by the following mechanism.
- the nonwoven fabric 2 is heated and pressed by the mold 5 via the jig 6. For this reason, the nonwoven fabric 2 is compressed and deformed to have the size and shape of the exterior material 11a to be molded.
- the part of predetermined depth from the surface which is in contact with jig 6 among nonwoven fabrics 2 reaches the temperature in the 1st temperature zone. Since the portion that has reached the temperature in the first temperature zone is in a state where plastic deformation due to thermoplasticity is easy, plastic deformation due to thermoplasticity (here, compression deformation) is caused by heating and pressurization.
- tool 2) has high temperature compared with the center side ( side in contact with the outer periphery of the predetermined part of the bundle
- the degree of plastic deformation due to thermoplasticity in the portion that has reached the temperature in the first temperature zone increases from the center side toward the surface side. For this reason, the density of the basic fiber and binder fiber in this part of the nonwoven fabric 2 is higher on the surface side.
- the axes of the basic fibers and binder fibers of the nonwoven fabric 2 are generally perpendicular to the compression direction (ie, parallel to the surface of the exterior material 11 a) by heating and pressing.
- the portion of the nonwoven fabric 2 where the basic fibers and the binder fibers are oriented in the direction parallel to the surface of the exterior material 11a has a particularly high density of the core fibers and the core fibers of the binder fibers compared to the other portions.
- the portion of the nonwoven fabric 2 that has reached the temperature within the first temperature zone melts the binder material of the binder fiber, and the molten binder material flows out between the basic fiber and the core fiber of the binder fiber. Thereafter, when the nonwoven fabric 2 is cooled to a temperature lower than the first temperature zone, the binder material that has melted and flowed out is solidified, and the core fibers and the core fibers of the binder fibers are bonded together.
- the density of the basic fiber and the core fiber is higher than that before pressing, and the axis of the core fiber of the basic fiber and the binder fiber is oriented in a direction parallel to the surface. Bonded by binder material. For this reason, a surface layer part becomes hard compared with the nonwoven fabric before being heated and pressurized. Also, since the axial direction of the core fiber and the core fiber of the binder fiber faces the direction parallel to the surface, the wear resistance is higher than in the state where the axis of the basic fiber and the binder fiber faces a random direction. .
- the first portion 111a has a higher density of core fibers of the basic fibers and the binder fibers than the other portions (and higher than the nonwoven fabric 2 before pressing and heating), and the axes of the core fibers of the basic fibers and the binder fibers are As a whole, it faces in the direction parallel to the surface (at least the ratio of the basic fiber and binder fiber core fiber whose axis is parallel to the surface is higher than the other parts), and the core of the basic fiber and binder fiber This is the part where the fibers are bonded together by the binder material.
- the portion of the nonwoven fabric 2 that is in contact with the outer periphery of the predetermined portion of the electric wire 12 or the bundle of electric wires 12 or a portion in the vicinity thereof does not reach the temperature within the first temperature range.
- the binder material of the binder fiber is not melted in these portions. Therefore, these portions have physical properties (for example, ease of deformation) of the nonwoven fabric before heating and pressurization.
- a softer portion than the first portion is formed in the portion in contact with the outer periphery of the predetermined portion of the electric wire or the bundle of electric wires and the portion in the vicinity thereof.
- This portion becomes the “second portion 112a”.
- the second portion 112a is a portion in which the binder material is not melted and has the properties of a nonwoven fabric before pressurization and heating.
- the portion closer to the center than the portion that has become the first portion 111a becomes the “third portion 113a”.
- the third portion 113a as in the first portion 111a, the basic fibers and the core fibers of the binder fibers are bonded to each other by the binder material melted and solidified. For this reason, it is harder than the second portion 112a.
- the degree of plastic deformation is smaller than that of the first portion 111a, and the direction of the axis of the core fiber and the core fiber of the binder fiber is greatly changed from the direction before heating and pressurization.
- the third portion 113a is softer than the first portion 111a.
- a third portion 113a having a shape is formed.
- the molded exterior material 11a is configured to cover a predetermined portion of the electric wire 12 or the bundle of electric wires 12 without a gap by the following mechanism.
- the nonwoven fabric 2 has a plate-like configuration and is bent to wrap a predetermined portion of the wire 12 or a bundle of wires 12, or the nonwoven fabric 2 has a sheet-like configuration.
- the non-woven fabric 2 has a rod-like configuration and a predetermined portion of the electric wire 12 or a bundle of electric wires 12 is accommodated in the slit 21, the inner surfaces of the slit 21 are bonded together by a binder material.
- the binder material of the fused binder fibers bonds the contact surfaces of the plurality of nonwoven fabrics 2. Therefore, the exterior material 11a comes to have the structure which covers the circumference
- the nonwoven fabric 2 is bonded to each other, a high bonding force can be obtained.
- an adhesive or the like is not necessary for bonding the nonwoven fabrics 2, so that the cost can be reduced. And since the process of “bonding the nonwoven fabrics 2 with an adhesive” is not necessary, the number of man-hours can be reduced (or the increase in man-hours can be prevented).
- the dimension of the first portion 111a (here, the dimension of the radius method when the exterior material 11a is viewed as a cylinder, the same applies hereinafter) is the step of heating and pressurizing the nonwoven fabric 2. It can be changed by adjusting one or both of the heating time and the heating temperature. That is, when the heating time is lengthened or the heating temperature is increased, the dimension of the first portion 111a is increased. On the other hand, when the heating time is shortened or the heating temperature is lowered, the size of the first portion 111a is reduced.
- the dimension of the first portion 111a can be changed by changing the dimension of the nonwoven fabric 2 to be attached in the step of attaching the nonwoven fabric 2 to a predetermined portion of the wire 12 or the bundle of the wires 12. That is, when the size of the nonwoven fabric 2 to be attached is increased, the degree of compressive deformation of the nonwoven fabric 2 is increased in the step of applying pressure while heating the nonwoven fabric 2. For this reason, the basic fiber and binder fiber of a nonwoven fabric which face the direction parallel to the surface of the exterior material 11a increase. If it does so, the dimension of the 1st part 111a will become large.
- the degree of compressive deformation of the nonwoven fabric 2 is reduced in the step of applying pressure while heating the nonwoven fabric 2. For this reason, the basic fiber and binder fiber of the nonwoven fabric 2 which face the direction parallel to the surface of the exterior material 11a decrease. If it does so, the dimension of the 1st part 111a will become small.
- the dimension of the 2nd part 112a and the 3rd part 113a of the wire harness 1a concerning 1st embodiment of this invention is the process which pressurizes heating the nonwoven fabric 2, One or both of heating time and heating temperature It can be changed by adjusting. That is, if the heating time is lengthened or the heating temperature is increased, the size of the portion reaching the temperature in the first temperature zone increases, so the size of the second portion 112a decreases, and the third portion 113a The dimensions increase. On the other hand, if the heating time is shortened or the heating temperature is lowered, the portion reaching the temperature in the first temperature zone becomes smaller, so the size of the second portion 112a becomes larger and the size of the third portion 113a becomes smaller. Get smaller.

Then, as shown in FIG. 12 (b), the nonwoven fabric 2 is compressed by being pressed by the forming tool 71. And the cross-sectional dimension and shape of the nonwoven fabric 2 become equal to the dimension and shape of the area
- molding tool 71 is heated to "predetermined temperature” by a heating means, maintaining the state shown in FIG.12 (b). This state is maintained for a “predetermined time”. That is, heating and pressurization of the nonwoven fabric 2 are continued over a “predetermined time”.
- the “predetermined temperature” is a temperature at which the nonwoven fabric 2 can be heated to a temperature within the “first temperature zone”.
- the “predetermined temperature” is a temperature within the “first temperature zone” or a temperature higher than that.
- the “predetermined time” is as follows. Of the nonwoven fabric 2, the portion in contact with the first forming tool 71 and the portion in the vicinity thereof (that is, the portion serving as the outer peripheral surface of the exterior material 11 g according to the seventh embodiment of the present invention and the portion in the vicinity thereof) It is the time to reach the temperature in the first temperature zone, but the portion in contact with the second molding tool 72 and the portion in the vicinity thereof (that is, the housing material for the wire harness according to the first embodiment of the present invention) The portion that becomes the inner peripheral surface of 11 g and the portion in the vicinity thereof are times when the temperature does not reach the temperature within the first temperature zone.
- the heating of the first molding tool 71 is stopped, and the heated and pressurized nonwoven fabric 2 (that is, the molded exterior material 11g according to the first embodiment of the present invention) ) Is cooled.
- the cooling method is not particularly limited. For example, a method of storing in a refrigerator, a method of spraying a normal or low temperature gas, a method of leaving in a normal temperature, and the like can be applied. Further, the molded exterior material 11g according to the seventh embodiment of the present invention may be cooled after being removed from the molding tool 7, or may be cooled while being accommodated in the molding tool 7.
- the exterior material 11g according to the seventh embodiment of the present invention having the first portion 111g, the second portion 112g, and the third portion 113g is formed by the following mechanism. Is done.
- the degree of plastic deformation due to thermoplasticity in a portion that has reached a temperature within one temperature zone increases from the inner peripheral surface side toward the outer peripheral surface side. For this reason, as for the density of the basic fiber and binder fiber in this part of the nonwoven fabric 2, the outer peripheral surface side becomes high.
- the basic fiber and binder fiber of the nonwoven fabric 2 by heating and pressurization Is generally oriented in a direction perpendicular to the compression direction (that is, a direction parallel to the outer peripheral surface).
- the density of the core fibers of the basic fibers and the binder fibers is particularly high in the portion in which the axes of the basic fibers and the binder fibers of the nonwoven fabric 2 are oriented in the direction parallel to the surface of the exterior material 11g.
- the portion of the nonwoven fabric 2 that has reached the temperature within the first temperature zone melts the binder material of the binder fiber, and the molten binder material flows out between the basic fiber and the core fiber of the binder fiber. Thereafter, when the nonwoven fabric 2 is cooled to a temperature lower than the first temperature zone, the binder material that has melted and flowed out is solidified, and the core fibers and the core fibers of the binder fibers are bonded together.
- the portion in contact with the first forming tool and the portion in the vicinity thereof have a higher density of basic fibers and core fibers than before pressurization, and the cores of the basic fibers and binder fibers.
- the fibers are bonded together by a binder material in a state where the axis of the fiber faces a direction parallel to the outer peripheral surface. For this reason, the surface layer part of an outer peripheral surface becomes hard compared with the nonwoven fabric before being heated and pressurized. Also, since the axial direction of the core fiber and the core fiber of the binder fiber faces the direction parallel to the outer peripheral surface, the wear resistance is high compared to the state where the axial line of the basic fiber and the binder fiber faces a random direction. Become.
- the surface layer portion of the outer peripheral surface of the exterior material 11g is formed on the surface layer portion of the outer peripheral surface of the exterior material 11g according to the seventh embodiment of the present invention.
- This portion becomes the “first portion 111g”.
- the density of the core fiber of the basic fiber and the binder fiber is higher than that of the other portion (and higher than the nonwoven fabric 2 before pressing and heating), and the axis of the core fiber of the basic fiber and the binder fiber is As a whole, it faces in the direction parallel to the surface (at least the ratio of the basic fiber and binder fiber core fiber whose axis is parallel to the surface is higher than the other parts), and the core of the basic fiber and binder fiber This is the part where the fibers are bonded together by the binder material.
- the portion of the nonwoven fabric 2 that is in contact with the second molding tool and the portion in the vicinity thereof do not reach the temperature within the first temperature zone. For this reason, the binder material of the binder fiber is not melted in these portions. Therefore, these portions have physical properties (for example, ease of deformation) of the nonwoven fabric before heating and pressurization. In this manner, a softer portion than the first portion is formed in the portion in contact with the second forming tool and in the vicinity thereof (that is, on the inner peripheral surface side). This portion becomes the “second portion 112g”. In other words, the second portion 112g is a portion in which the binder material is not melted and has the properties of a nonwoven fabric before pressurization and heating.
- the portion on the inner peripheral surface side from the portion that has become the first portion 111g is the “third portion 113g”.
- the third portion 113g as in the first portion 111g, the basic fibers and the core fibers of the binder fibers are bonded to each other by the binder material melted and solidified. For this reason, it is harder than the second portion 112g.
- the degree of compressive deformation is smaller than that of the first portion 111g, and the direction of the axis of the basic fiber and the core fiber of the binder fiber is not greatly changed from the direction before heating and pressurization (that is, For example, it is not a configuration in which it faces a random direction or “a direction that is parallel to the outer peripheral surface as a whole”). For this reason, the third portion 113g is softer than the first portion 111g.
- the dimension of the first portion 111g (here, when the outer peripheral material 11g according to the seventh embodiment of the present invention is viewed as a “cylinder”, the dimension in the direction perpendicular to the axial direction of the “cylinder” is The same applies hereinafter) can be changed by adjusting one or both of the heating time and the heating temperature in the step of heating and pressurizing the nonwoven fabric 2. That is, if the heating time is lengthened or the heating temperature is increased, the dimension of the first portion 111g is increased. On the other hand, when the heating time is shortened or the heating temperature is lowered, the size of the first portion 111g is reduced.
- the dimension of the first portion 111g can be changed by changing the dimension of the nonwoven fabric 2 before being molded into the exterior material according to the seventh embodiment of the present invention. That is, when the size of the nonwoven fabric 2 is increased, the degree of compressive deformation of the nonwoven fabric 2 is increased in the step of applying pressure while heating the nonwoven fabric 2. For this reason, the basic fiber and binder fiber of a nonwoven fabric which face the direction parallel to the outer peripheral surface of the exterior material 11g increase. If it does so, the dimension of the 1st part 111g will become large. On the other hand, when the size of the nonwoven fabric 2 to be attached is reduced, the degree of compressive deformation of the nonwoven fabric 2 is reduced in the step of applying pressure while heating the nonwoven fabric 2. For this reason, the basic fiber and binder fiber of the nonwoven fabric 2 which face the direction parallel to the outer peripheral surface of the exterior material 11g decrease. If it does so, the dimension of the 1st part 111g will become small.
- the dimensions of the second portion 112g and the third portion 113g of the outer packaging material 11g according to the seventh embodiment of the present invention are either the heating time or the heating temperature in the step of pressurizing the nonwoven fabric 2 while heating. It can be changed by adjusting both. That is, if the heating time is lengthened or the heating temperature is increased, the size of the portion reaching the temperature in the first temperature zone increases, so the size of the second portion 112g decreases, and the third portion 113g The dimensions increase. On the other hand, if the heating time is shortened or the heating temperature is lowered, the portion reaching the temperature in the first temperature zone is reduced, so the volume of the second portion 112g is increased and the dimension of the third portion 113g is increased. Get smaller.
