Abstract

PURPOSE:To correct the direction of flow-down and give a variety in the color on the flow- down face by constituting in the flow-down face of the energy collecting medium flow of a flow-down type energy collector a section that is excellent and a section that is poor in liquid holding property. CONSTITUTION:A material which consists of a synthetic resin base material A with the surface of which a cloth B of natural fiber or synthetic fiber that has liquid holding property is in face contact or a material which consists of a cloth B on one face of which synthetic resin is coated is used as the material. On the surface of the outside of the cloth molten resin C is supplied by a resin supply means 2 that is movable in the direction along the direction of flowing down of an energy collecting medium, and through many communication holes such as interstices or the holes in the weaving pattern of the cloth the molten resin C is made to adhere to the synthetic resin base material A. By cooling the resin is solidified to fix the cloth to the synthetic resin base material and, on the other hand, a section which has the liquid holding property reduced is formed on the cloth so as to restrict the direction of flowing down of the energy collecting medium and it is given directionality. And, by a diversification of the synthetic resin base material, cloth, and molten resin many designs of flowing down face are provided.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid transfer regulating sheet,
In particular, the present invention relates to a method for manufacturing a sheet used for regulating the flow of a heat medium liquid.

[0002]

2. Description of the Related Art A method of providing a regulation line along a heat collecting surface and restricting the flowing direction of a heat collecting medium by the regulation line is disclosed in, for example, Japanese Patent No. 269189 by the same applicant as the present application.
No. 8 (Japanese Patent Application No. 62-134376). No. 2639937 (Japanese Patent Application No. 62-173715) and Japanese Patent No. 2655 by the same applicant.
No. 327 (Japanese Patent Application No. 62-182940) shows some specific examples of the regulation line.

[0003]

The present applicant has repeated many studies and experiments on the reference line. In conclusion, many different forms of the regulation line are required depending on the application. For example, in the field of heat collectors, there is a tendency to attach great importance to appearance design. Individual production technologies cannot at all respond to various design designs while ensuring heat collection performance tailored to the various uses of the customer. There is a need for specific high-mix low-volume production technology that can be easily implemented using simple equipment. In addition, the conventional normal line structure easily peels, and there is still room for improvement in durability.

According to the present invention, a fiber material having a liquid retaining property is brought into surface contact with a surface of a synthetic resin substrate, or a synthetic resin is coated on the surface of the fiber material. While preparing the material, moving the material in a stationary state or continuously or intermittently, the molten resin is continuously or intermittently discharged from the movable resin supply means to the fiber material, and the stitches of the fiber material are stitched. The molten resin is contacted and adhered to the synthetic resin substrate through a large number of conductive holes such as fibers and weaves, and the resin is solidified and the fiber material is fixed to the synthetic resin substrate. Forming a part having reduced liquid retention compared to the other part of the part, and using the part with reduced liquid retention and other parts to regulate the movement of the liquid flowing down. A sheet manufacturing method is obtained.

[0005]

[Function and Effect] A desired shape of the ruled line pattern can be easily drawn by the relative movement of the fiber material and the resin supply means. Therefore, without stopping the production line, the form of the setting line is changed for each lot while continuously or intermittently feeding the fiber material or the synthetic resin base material, and sheets having various required setting patterns are manufactured. If a synthetic resin base material or a fiber material is replaced, a very large number of product groups can be switched and produced. For example, a synthetic resin substrate, prepare 20 different types of fiber material,
If 50 kinds of patterns can be drawn by the resin supply means, and if five kinds of molten resin supplied from the resin supply means can be prepared, there are advantages that a total of 5000 kinds of sheets can be produced in total.

The solidified resin layer is adhered to the surface of the base material with a fiber material interposed therebetween, thereby forming a portion having reduced liquid retention, fixing and holding the fiber material, and removing the fiber material for a long period of time. Can be fat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a laminated material in which a fiber material B of a natural fiber or a synthetic fiber having a liquid retaining property is brought into surface contact with the surface of a synthetic resin base material A, or a synthetic resin is applied to one surface of the fiber material B. Refers to the material coated with layer A. While the material 1 is stationary or continuously or intermittently moved, the molten resin C is applied to the outer surface of the fiber material by the resin supply means 2 movable in the direction along the flowing direction of the heating medium liquid. It is supplied continuously or intermittently. The supplied molten resin C comes into contact with the synthetic resin base material through a number of conductive holes such as stitches and weaves of the fiber material, and exhibits an adhesive effect. If the resin is solidified by cooling,
The fiber material B is fixed to the synthetic resin base material. The fixed portion forms a portion in which the resin closes the eyes of the fiber material and has a lower liquid retaining property than other portions of the fiber material. The flow direction of the heat transfer medium flowing down the other portion in the portion where the liquid retaining property is reduced can be regulated to give directionality.

By moving the resin supply means 2 in a plane biaxial direction, the molten resin C adheres to the surface of the fiber material B obliquely or in an arc across the flowing direction of the heat medium liquid. it can. In the illustrated example, the resin supply means 2 is constituted by a series of nozzles arranged in parallel.

After the molten resin is supplied through the resin supply means, the thickness can be adjusted by pressing the resin by the pressure roller 4 before and after the cooling operation using the cooling means 3 of the air blower.

The fiber material B has an arbitrary color tone and / or color pattern capable of collecting heat. In addition, the exposed surface of the synthetic resin substrate A can also have an arbitrary color tone and / or color pattern capable of collecting heat.

[0011] According to the sheet manufactured as described above, the heat medium liquid flows mainly down to the surface of the fiber material to which the resin is not adhered. The finished sheet has no distinction between front and back.

Various types of synthetic resin materials can be used for the synthetic resin substrate. Further, as the fiber material, for example, a cotton fabric, an acrylic fabric, or a polyester fabric can be used.
