CHRYSANTHEMUM-SHAPED ELEMENT AND METHOD FOR MANUFACTURING THE SAME, FILTER BODY AND FLUID FILTER |
摘要 |
The chrysanthemum-shaped element is in a cylindrical shape in which folds are formed and inner surfaces of adjacent folds are bonded at their top and bottom edges. The chrysanthemum-shaped element includes (A) an element body composed of a filter medium having a filter paper and a low-melting fiber layer formed on a surface of the filter paper on the inner surface side of the folds at least at the top and bottom edges of the filter paper; and (B) bonding sections formed at the top and bottom edges on inner surfaces of the folds by heat-adhesion of the low-melting fiber layer. The low-melting fiber layer is made of a fiber having a lower melting point than that of filter paper materials that form the filter paper and/or compound fibers which contain a fiber of a lower melting point than that of the filter paper material.
