Fibre ya Sepiolite ni ubwoko bw'imitako karemano, ikaba ari ubwoko bw'imitako ya sepiolite ifite utwuma duto, yitwa α - sepiolite. Sepiolite ni ubwoko bw'imitako ya silicate ifite umunyururu. Mu miterere ya sepiolite, urwego rwa octahedron ya magnesia rushyirwa hagati ya tetrahedroni ebyiri za silicon ogisijeni, rugakora imiterere ya 2:1. Urwego rwa tetrahedral rukomeza kandi icyerekezo cya ogisijeni ikora muri urwo rwego gihinduka buri gihe. Urwego rwa octahedral rukora umuyoboro ugororotse hagati y'urwego rwo hejuru n'urwo hasi. Icyerekezo cy'umuyoboro gihuye n'umurongo wa fibre, bigatuma molekile z'amazi, cations z'ibyuma, molekile nto z'ibinyabuzima n'ibindi byinjira. Sepiolite ifite ubushobozi bwo kurwanya ubushyuhe. Sepiolite kandi ifite ubushobozi bwo guhinduranya iyoni neza no gukamura, ndetse no kurwanya ingese, kurwanya imirasire, gukingira ubushyuhe n'indi miterere myiza, cyane cyane Si Oh mu miterere yayo ishobora gukorana neza n'ibinyabuzima kugira ngo ikore ibikomoka ku mitako y'ibinyabuzima.

Sepiolite ikoreshwa cyane mu bijyanye no gutunganya, gutunganya no guhindura ibintu neza cyane. Sepiolite ishobora gukoreshwa nk'inyunganiramirire, isukura, deodorant, inyunganiramirire, inyunganiramirire, inyunganiramirire, inyunganiramirire y'amazi, inyunganiramirire, inyunganiramirire y'ingufu, ifumbire mvaruganda, ibiryo by'amatungo n'izindi nganda. Byongeye kandi, sepiolite ifite ubushobozi bwo kurwanya umunyu no kurwanya ubushyuhe bwinshi, bityo ikaba ishobora gukoreshwa nk'ibikoresho byo gucukura ibyondo byiza mu gucukura peteroli, gucukura amazi ashyushye n'ibindi.

Fibre ya Sepiolite ikomoka kuri fibre y'ubutare, iboneka mu ibuye ry'ubutare. Ibice byayo by'ingenzi ni okiside zitandukanye, nka silica, alumina, magnesium oxide, nibindi. Inkomoko yayo y'ingenzi ni ubwoko bwose bwa asbestos, nka chrysotile, ipamba rya bluestone, nibindi. Fibre y'ubutare irimofibre ya silicate ya aluminiyumu, fibre y'ikirahure, fibre ya gypsum, fibre ya karuboni, n'ibindi.
