性を保持し得なくなる等の欠点がある。 However, in the above-mentioned known contact materials, elastic threads made of urethane rubber or the like are used as part of the wires constituting the braid, and loops are formed in a spiral shape by utilizing the elasticity of the threads. The shaped loop has no waist, and the spiral strands look like a rubber string,
In addition, since the loops are elastic and easily come off, it is necessary to incorporate a core material into the braided cord cord or to secure it with adhesive.Furthermore, it is necessary to treat the ends and tie them together when using them, which makes handling work difficult. The sex is extremely bad. As a result, the weight of the contact material itself becomes large, the cost becomes high, and there are disadvantages such as the inability to maintain long-term stability of the contact material.

なわれるものである。 Incidentally, when a contact material consisting of a braided cord formed into a spiral loop is applied to sewage treatment, the amount of active microorganisms required to effectively purify the sewage is attached to and retained in the loop. Therefore, the sewage can be effectively purified by the action of microorganisms.

ている。Means for Solving the Problems In the present invention, fibers made of a thermoplastic resin with a high heat shrinkage rate are used for the strands constituting the braid for forming the loops into a spiral. When the formed material is heat-treated, the loop becomes spiral due to its contractility and is stably fixed. The formation state of the spiral loop will be explained based on the drawings attached here.
FIG. 1 shows an example of the form of loops 2 formed in a braided cord 1 by arranging them in a row at right angles to the longitudinal direction of the braided cord 1. When the braided cord forming the loops 2 is heat-treated and twisted, As shown in FIG. 2, the loops 2 arranged in a row are turned into a spiral, and the thermoplastic resin fibers having a high heat shrinkage rate are strongly heat-shrinked by heat treatment, and the braided structure is heat-set and the helical form is heat-set. FIG. 3 shows a state in which the degree of spiralization has progressed considerably and is fixed, and illustrates the form of the contact material according to the present invention.

維を用いる。 Next, in the present invention, examples of fibers made of a thermoplastic resin having a high heat shrinkage rate and used as wires for forming loops into spirals include polyvinyl chloride, nylon, polypropylene, polyethylene, etc. Particularly preferred are synthetic fibers, which shrink significantly upon heating to about 90-100°C, so that the heat treatment to form the helical loops can also be carried out at relatively low temperatures. If the fiber used to form the loop is a single fiber of 50μ to 150μ, and the outer diameter of the loop itself is 25mm to 50mm, the surface area of the loop will increase, allowing better attachment and retention of microorganisms and preventing air contact. Becomes good. In the contact material of the present invention, in addition to vinylidene chloride fibers, polyvinyl chloride, polyvinylidene fluoride, nylon, polyester, polyethylene, polypropylene, polyacrylic fibers, etc. are used for the braided cord itself.
