Description

  The present invention relates to a liquid-permeable winding tube for winding a fiber material such as a fiber for plating a metal, a fiber bundle or a thread.

  When electrolessly plating a metal on a yarn, as exemplified in Patent Document 1, the yarn is wound on a winding tube with soft cheese. A cylindrical wound body is formed concentrically around the outer circumference of the cylindrical winding tube. The winding cylinder wound with the yarn is inserted into the tubular shaft of the plating apparatus. A plating solution is supplied into the tubular shaft. The plating solution sequentially passes through the liquid-permeable peripheral wall of the tubular shaft and the liquid-permeable peripheral wall of the winding cylinder, and passes through the liquid-permeable winding body around the winding cylinder. The yarn of the wound body comes into contact with the plating solution and is subjected to a plating treatment. The yarn of the wound body is sequentially subjected to various plating processes and then dried by receiving hot air.

  The winding tube is a cylindrical synthetic resin molded product. In the peripheral wall, the liquid passage holes penetrate, and the square liquid passage holes are arranged at equal intervals in the axial direction and the circumferential direction, respectively. A large number of rectangular liquid passage holes are arranged vertically and horizontally to form a lattice shape.

  When metal plating is performed by winding a yarn, fiber bundle or fiber around a liquid-permeable winding tube, the metal plating may not evenly adhere to the yarn, fiber bundle or fiber. There may be a place where there is a plating film and a place where there is no plating film. In particular, when the yarn, fiber bundle, or fiber filament is thin, for example, when the weaving degree is 44 [dTex] or less, plating unevenness occurs. Further, when there are a large number of filaments of yarns or fiber bundles, for example, when there are 25 or more filaments, uneven plating occurs.

[Idea for solving problems]
1) It was speculated that the reason why the metal plating becomes uneven is that the plating solution does not pass through each part evenly when passing through the outer periphery of the winding tube, and the passing position is biased. In view of this, the winding cylinder is designed to increase the liquid permeability by enlarging each liquid passage hole.

  However, when the rectangular liquid passage hole becomes large, the winding tube has a narrow lattice-shaped axial bar portion and a circumferential bar portion, and the strength is reduced. In addition, when the synthetic resin winding tube receives hot air for drying after the plating process, it is heated and softened. When the synthetic resin winding cylinder having high liquid permeability is heated in a state of receiving a force from the outer winding body, it is deformed or crushed. Cannot be reused.

  2) The reason why a highly liquid-permeable winding tube is deformed by heating for drying is that it is made of a synthetic resin that has low strength and is softened by heating. Therefore, the winding tube should be made of metal. It was.

  However, the plating solution has a strong acid solution such as a pretreatment solution for applying a catalyst. Therefore, if the material of the winding tube is a general steel material as a metal material, it is a highly acidic catalyst application solution. Corrosion will occur. Titanium, gold, and platinum are examples of metals that can withstand a highly acidic plating solution such as a catalyst-providing solution. Gold and platinum are expensive noble metals and are not suitable for the structural material of machine parts. I noticed that the material of the winding tube is titanium, pure titanium or titanium alloy, which is a structural material with high corrosion resistance and heat resistance. In addition, a material in which a metal structure material such as general steel or stainless steel is coated with a coating having high corrosion resistance and heat resistance such as polytetrafluoroethylene (registered trademark “Teflon”), corrosion resistance and heat resistance It was also conceived to use a surface-treated metal structural material having a high level.

  That is, as the material of the winding tube, a titanium material or a surface-treated metal structure material having corrosion resistance and heat resistance is adopted.

  3) Unlike conventional synthetic resins, the titanium material or surface-treated metal structural material used for the material of the winding cylinder has a high bending strength even when it is formed into an elongated rod shape and receives hot air for drying after plating. Therefore, in order to improve the liquid permeability, the winding tube has a liquid passage hole in the shape of an elongated groove along the axial direction instead of the conventional square shape, and the length of the groove is set to the winding width of the fiber material. They are almost equal and are arranged in parallel at equal intervals in the circumferential direction. The winding tube has a vertical stripe shape with a large number of longitudinal groove-shaped liquid passage holes arranged side by side.

1) In a liquid-permeable winding tube in which a fiber material such as a fiber for plating metal, a fiber bundle or a thread is wound, is in contact with a plating solution, and is heated for drying after the plating treatment.
The material is a titanium material or a surface-treated metal structure material having corrosion resistance and heat resistance,
The shape is a cylindrical shape, penetrating a number of liquid passage holes in the peripheral wall,
The liquid passage hole was formed in the shape of an elongated groove along the axial direction, and the length of the groove was made substantially equal to the winding width of the fiber material, and was arranged in parallel in the circumferential direction.

2) In a liquid-permeable winding tube in which a fiber material such as a fiber to be plated with metal, a fiber bundle or a thread is wound, is in contact with a plating treatment solution, and is heated for drying after the plating treatment.
It consists of an annular member and a rod-like member, and the material of both members is a titanium material or a surface-treated metal structural material having corrosion resistance and heat resistance,
Two annular members are arranged concentrically and spaced apart, and a large number of rod-like members are arranged along the axial direction of the annular member and are arranged in parallel in the circumferential direction of the annular member. Both ends of each rod-shaped member are fixed to the member, and both annular members are connected by a large number of rod-shaped members,
An elongated groove-shaped liquid passage hole is formed between two adjacent rod-shaped members and the annular members on both sides along the axial direction, and the axial length of the liquid passage hole is substantially equal to the winding width of the fiber material. did.

  The winding tube for fiber material plating has an elongated groove shape in which the liquid passage hole has a length substantially equal to the winding width of the fiber material, and is arranged in parallel in the circumferential direction. High liquid permeability. Moreover, the material is a titanium material or a surface-treated metal structure material having corrosion resistance and heat resistance. It withstands a highly acidic plating treatment solution such as a catalyst application solution and drying heat after the plating treatment.

  Therefore, metal plating is easily adhered evenly to fiber materials such as yarns, fiber bundles and fibers.

  As shown in FIGS. 1 and 2, the winding tube for plating the fiber material has a cylindrical shape, and includes two annular members 1 and a large number of rod-like members 2. The material of the annular member 1 and the rod-like member 2 is a titanium material of pure titanium.

  The two annular members 1 are arranged vertically in a concentric manner at an interval substantially equal to the winding width of the fiber material of the winding tube. Each rod-shaped member 2 has a length substantially equal to the winding width of the fiber material, and is disposed between the upper and lower annular members 1. A large number of rod-shaped members 2 are arranged along the axial direction and the vertical direction of the annular member 1, and are arranged at equal intervals in the circumferential direction of the annular member 1. Each rod-like member 2 is fixed by welding both ends to the inner end face of both annular members 1. Both annular members 1 are connected by a large number of rod-like members 2.

  Between the two adjacent rod-shaped members 2 and the annular members 1 on both sides, an elongated groove-shaped liquid passage hole 3 is formed penetratingly formed along the axial direction and the vertical direction of the winding cylinder. The liquid passage hole 3 has a length in the winding cylinder axis direction substantially equal to the winding width of the fiber material, and is arranged in parallel in the circumferential direction at equal intervals.

  The winding cylinders 1 and 2 are formed in a vertical stripe shape with a large number of longitudinal groove-shaped liquid passage holes 3 arranged side by side. High liquid permeability. The aperture ratio exceeds 70%. 2 to 3 times the conventional product.

  The winding cylinders 1 and 2 have the approximate dimensions shown in italics in FIG. Sixteen groove-shaped liquid passage holes 3 are arranged in parallel at an interval of about 2 [mm]. Each liquid passage hole 3 has a length of about 150 [mm] which is substantially equal to the winding width of the fiber material, and a width of about 11 [mm]. The aperture ratio is about 75%.

[Usage example 1]
In this usage example, as shown in FIGS. 3 and 4, the fiber bundle is wound with soft cheese around the winding cylinders 1 and 2 of the embodiment. A wound body f of fiber bundles is formed in a cylindrical shape. All the liquid passage holes 3 are covered with the wound body f over their entire length.

  A fiber bundle is a bundle of filaments. The type is aramid, the mass is 300 [g], the weaving degree is 66 [dTex], and the number of filaments is 1000. This is an example with a large number of filaments.

  The winding cylinders 1 and 2 wound with the fiber bundle are inserted into the tubular shaft of the plating apparatus, and the plating solution is supplied into the tubular shaft. The plating solution sequentially passes through the liquid-permeable peripheral wall of the tubular shaft and the liquid passage holes 3 of the winding cylinders 1 and 2 and passes through the liquid-permeable winding body f around the winding cylinders 1 and 2. After the plating solution flows from the inside to the outside in this way, it flows backward and flows from the outside to the inside. Repeat forward and reverse flow. The fiber bundle of the wound body f comes into contact with the plating solution and is subjected to a plating process.

  The fiber bundle of the wound body f sequentially contacts various plating treatment solutions for electroless silver plating and sequentially receives various plating treatments. The plating solution includes a highly acidic solution containing about 30% hydrochloric acid and a catalyst providing solution. The fiber bundle of the wound body f is dried by receiving hot air after the plating process is completed. The temperature of the hot air is about 100 [° C.]. The fiber bundle is electrolessly plated with silver.

  The fiber bundle of the wound body f on which the electroless silver plating was applied was rewound onto the bobbin by one third. Each of the silver-plated fiber bundles divided into three equal parts was measured for electric resistance. All of the silver-plated fiber bundles had an electric resistance value of 1 [cm] of 0.00 [Ω] or less. It is recognized that the silver bundle is uniformly attached to the fiber bundle over the entire length.

In this use example, the fiber bundle is of polyester type, has a mass of 600 [g], a weave degree of 44 [dTex], and 18 filaments. This is an example of a thin filament. This fiber bundle is wound around the winding cylinders 1 and 2 in the same manner as in the first use example, and is subjected to electroless silver plating.

  The fiber bundle of the wound body in which silver was electrolessly plated was rewound onto the bobbin by 1/6. Each of the silver-plated fiber bundles divided into 6 parts was measured for electric resistance. All of the silver-plated fiber bundles had an electric resistance value of 1 [cm] of 0.00 [Ω] or less. It is recognized that the silver bundle is uniformly attached to the fiber bundle over the entire length.

[Usage example 3]
In this use example, the fiber bundle is of polyester type, has a mass of 600 [g], a weave degree of 33 [dTex], and 12 filaments. This is an example of a very thin filament. This fiber bundle is wound around the winding cylinders 1 and 2 in the same manner as in the first use example, and is subjected to electroless silver plating.

  The fiber bundle of the wound body in which silver was electrolessly plated was rewound half by half onto the bobbin. Each of the fiber bundles with silver plating divided into two was measured for electric resistance. All of the silver-plated fiber bundles had an electric resistance value of 1 [cm] of 0.00 [Ω] or less. It is recognized that the silver bundle is uniformly attached to the fiber bundle over the entire length.
