Abstract

PURPOSE:To produce industrially and efficiently by weaving a bamboo blind- shaped woven fabric using a hollow yarn membrane as a weft in laminating a porous hollow yarn membrane in layers on the outer circumference of a cylindrical body. CONSTITUTION:A porous hollow yarn membrane is used as a weft 1 arranged in the specified pitch, and the form of a bamboo blind is maintained by a closely arranged warp 2. The pitch W of the warp 2 is made slightly larger than the length of the cylindrical body. The part of the warp 2 of the bamboo blind- shaped woven fabric is coated with a bonding agent or a tackifier. Both ends of the warp 2 are made to coincide with both ends of a flange. And the woven fabric is wound in the form of a roll to form the hollow yarn layer. The weft is fixed to the flange and the cylindrical body with resin at the part of the flange adjacent to the warp zone and at the cylindrical part adjacent to the flange part. The resin-fixed part is cut to obtain the module.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a 1L module using a porous hollow fiber membrane.

Traditionally, porous hollow fiber membranes made of polypropylene, polyethylene, etc. have been used for sterilization of drinking water, water for washing hands in hospital operating rooms, etc., and for the separation of blood cells and plasma in blood, artificial lungs, renal PE, A analysis, etc. It is primarily used in the medical field. In most cases, this porous hollow fiber membrane is used as a module with a round shape V-shaped structure suitable for its intended use.

The present invention is directed to the production of a module in which a porous thread layer is arranged around a cylindrical object (hereinafter collectively referred to as a cylindrical object) among these cylindrical shapes. The present invention provides a method.

The gist is that flanges are installed at both ends of a cylindrical object, the distance between adjacent warp fluorescent zones is slightly larger than the length of the cylindrical object, and the distance between the centers of the light zones is What is the length of a cylindrical object equipped with a flange?〈Warps are arranged so that they are equal, and a sag-like fabric is woven using porous hollow fibers as wefts.A pressure-sensitive adhesive or adhesive is placed in the warp zone. , MiJ
After arranging the warp zone around the circumference of the flange at both ends of the cylindrical object and rolling up the sway-like fabric into a predetermined layer, the flange portion and/or the flange portion adjacent to the warp zone A method for manufacturing a module, characterized in that the part is fixed to a flange and/or a cylindrical object with resin at the cylinder gb adjacent to , and cut at the resin fixed part □ The following drawings show: Further along i? 1WIIK Explain.

FIG. 1 GYU provided for the present invention 11. This figure shows a sagging-like woven fabric using gauze-like hollow fibers for the weft.

In Fig. 1, pouka hollow fibers are used as the weft yarns (1) arranged at a predetermined pitch, and the warp yarns (1) are finely arranged.
The sudare-like shape is maintained by The pitch W of the warp yarns (U) is arranged slightly longer than the length of the circular object described later. The warp yarns may be made of any material, such as various natural fibers or synthetic fibers, and the type of yarn may be spun yarn, filament yarn, or processed yarn.

Normally, when a porous hollow fiber membrane is subjected to high tension or its surface is strongly abraded, its structure is easily destroyed, so in the weaving process, the weaving process is done in a way that allows for low tension and yet does not cause strong abrasion. It is preferable to stay away.

The first time shows the situation in which l pitch of the sagging woven fabric shown in Figure 1 is wrapped around a cylindrical object. In the figure, rubber or A resin flange is attached.

On the other hand, an adhesive or pressure-sensitive adhesive (not shown) is applied in advance to the warp (warp zone) of the sagging woven fabric. It may be a so-called double-sided tape with adhesive or adhesive applied on both sides, or the warp zone [adhesive or adhesive may be applied.

The width (d
It is preferable that the thickness of the warp (2) is smaller than the thickness of the flange (1), and that both ends of the warp (2) have a flange of 0.25 mm. (It is placed so that it matches both sides of the flange and rotates with the shaft (J) in the direction of the arrow to be wound in a sushi-maki shape.Therefore, the warp threads (J) have 1N15 minutes, and both ends are attached to the flange.

As a result, a weft (1), that is, a layer of porous hollow fibers, is formed on the outer circumference of the cylindrical object (3).

, (4')' is attached to the cylindrical object (3), and the porous hollow fiber layer (A) formed on the outer periphery is such that the r13 portion of (d) of the warp (C) is The warp (2) and the tape-like material (gradient) form a dense layer formed in layers, but in the other parts, there is no warp (2) or tape-like material (&), and 411 layers are formed. Next, resin is injected into the warp section VC at both ends of the sushi roll and/or in the vicinity of the flange, solidified, and then fixed with resin.

Since the layer is rough, the resin can sufficiently penetrate into the inner layer.

FIG. 7 is a perspective view of a module obtained by injecting and solidifying the resin into the material shown in FIG. The cut surface shows a state in which a large number of porous hollow fiber curved surfaces (J) fixed to the resin are exposed. Such a module is usually housed in a VC housing (not shown) and is used for various purposes.As detailed above, by the method of the present invention, rL is Using a ring, it is possible to efficiently form a sag-like material, and when resin is injected, it can penetrate evenly to the inner layer, making it extremely easy to manufacture modules in a short time. It will greatly contribute to the industry since it will be possible to luxuriously improve productivity.
