Tsis ntev los no, acomet fiber lim mediauas sib txuas cov kev hloov pauv ntawm cov fibers nrog kev ruaj ntseg ntawm cov khoom tau raug txhawb rau kev siv hauv kev kho dej. Ua los ntawm qhov siab - ntom ntom "comet nucleus" core thiab elastic fiber ntau "comet tail" filaments, cov xov xwm lim dej no khaws cov txiaj ntsig ntawm thaj chaw loj tshwj xeeb thiab muaj peev xwm adsorption siab ntawm fiber ntau lim cov ntaub ntawv, thaum daws cov teeb meem ntawm kev yooj yim entanglement thiab nyuaj backwashing ntawm cov tsoos fibers.
Nws tau tshaj tawm tias cov xov xwm lim dej no tau sib xws nrog cov khoom siv fiber ntau uas twb muaj lawm. Hauv cov dej phwj hauv nroog thiab kev kho dej khib nyiab hauv nroog, nws tuaj yeem cuam tshuam cov impurities xws li tshem tawm cov khib nyiab thiab cov colloids. Nws qhov kev pom tseeb yog kwv yees li 20% siab dua li cov khoom siv ib txwm siv, kev siv dej rov qab yog txo los ntawm 15%, thiab nws lub neej kev pabcuam tuaj yeem ncav cuag 3 txog 5 xyoos. Cov neeg sab hauv kev lag luam tau hais tias nws "siab-kev ua haujlwm zoo + kev saib xyuas yooj yim" ua rau nws muaj kev cog lus tshiab rau cov khoom siv lim dej.
