液体濾過フィルター及び液体濾過フィルターの製造方法

Liquid filtering filter and its manufacturing method

Abstract

PROBLEM TO BE SOLVED: To provide a liquid filtering filter having a low pressure loss and a long service life. SOLUTION: This liquid filtering filter is constituted by piling crimped short fibers, compressing the piled fibers and forming the compressed fibers into a block-like shape so that a liquid can be made to pass preferentially to the direction of the thick arrow shown in the figure. The fibers are bonded to one another at the positions being in contact with one another, arrayed so that the longitudinal direction of each of the fibers is adjusted to only one direction (X-direction) perpendicular to the fiber-piled direction (Z-direction) and compressed only to the fiber-piled direction. All of the fibers to be used are composed of two kinds of synthetic fibers. The melting point of one of the synthetic fibers is made lower relatively than that of the other of the synthetic fibers so that the low-melting point synthetic fibers can be bonded to one another at the contact positions by heating and fusing the fibers.

【課題】低圧損で長寿命の液体濾過フィルターを提供すること。 【解決手段】捲縮された短繊維の積層圧縮ブロック状体で構成されて図示の太い矢印方向に優先的に通液可能に設けられている。各短繊維は、互いに接触する箇所で接着されていると共に、その長手方向が繊維積層方向(Z方向)と直交する一方向(X方向)のみに向けられ、かつ繊維積層方向のみに圧縮されている。なお、短繊維は、合成繊維で構成され、その一方の合成繊維が、他方の合成繊維よりも相対的に低融点であって加熱溶融されて接触箇所で接着されている。 【選択図】 図1
