FILTER MEDIUM AND METHOD FOR MANUFACTURING THE SAME
PROBLEM TO BE SOLVED: To obtain a filter medium having sufficiently low pure water extraction conductivity and to provide a method for inexpensively mass-producing the filter medium. SOLUTION: The filter medium contains 40 wt.% or more of organic fibrile fibers and has pure water extraction conducti...

SOLUTION: The filter medium contains 40 wt.% or more of organic fibrile fibers and has pure water extraction conductivity of <10 μS/cm and is manufactured from a raw material, which is prepared by mixing 80% of lyocell fibers (web Young's modulus =26 g/d) with 1.7 decitex ×4 mm C.S.F=230 ml and 20% of core-sheath PET fibers with 1.7 decitex ×4 mm, by a wet papermaking process so as to become a basis weight of 35 g/m2. This filter medium has collection efficiency of 70%, pressure loss of 23 mmaq and a low pure water extraction conductivity value of 7 μS/cm.</description><edition>7</edition><language>eng</language><subject>IMPREGNATING OR COATING OF PAPER ; PAPER NOT OTHERWISE PROVIDED FOR ; PAPER-MAKING ; PERFORMING OPERATIONS ; PHYSICAL OR CHEMICAL PROCESSES OR APPARATUS IN GENERAL ; PREPARATION THEREOF NOT COVERED BY SUBCLASSES D21C OR D21D ; PRODUCTION OF CELLULOSE ; PULP COMPOSITIONS ; SEPARATION ; TEXTILES ; TRANSPORTING ; TREATMENT OF FINISHED PAPER NOT COVERED BY CLASS B31 OR SUBCLASS D21G</subject><creationdate>2001</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20011030&DB=EPODOC&CC=JP&NR=2001300225A$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,780,885,25563,76318</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20011030&DB=EPODOC&CC=JP&NR=2001300225A$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>KUBO OSAMU</creatorcontrib><creatorcontrib>NISHIU MASAMICHI</creatorcontrib><creatorcontrib>TSUCHIKAWA KEIICHI</creatorcontrib><creatorcontrib>AKIYAMA KOSUKE</creatorcontrib><creatorcontrib>MIO JIRO</creatorcontrib><title>FILTER MEDIUM AND METHOD FOR MANUFACTURING THE SAME</title><description>PROBLEM TO BE SOLVED: To obtain a filter medium having sufficiently low pure water extraction conductivity and to provide a method for inexpensively mass-producing the filter medium.
