<p>PURPOSE:To inhibit the formation of large colonies of microorganisms at the stem part of a carrier, to improve the flow of liquid and to facilitate the fixation and proliferation of microorganisms, by using filaments as a carrier and planting the filaments to a stem in a manner to form large U-shaped loops. CONSTITUTION:Each weft yarn 6<1>...6<9>, 7<1>...7<9> is extended far beyond the stem 8, bent gradually forming a large loop R and introduced again into the stem 8 to form a large U-shaped loop. The weft yarn is e.g. polyvinylidene chloride, nylon, carbon fiber, glass fiber, stainless steel fiber, etc., and the material of the stem 8 is preferably polypropylene or metallic fiber having smooth surface. The development of large colonies of microorganisms and the stagnation of the liquid near the stem can be prevented by the use of the above structure.</p> |
