Imiti ya chimique nuburyo bukoreshwa muburyo bwo gukoresha imiti no gusya nyuma yo kuvurwa.Ubwa mbere, kora witonze (kwibiza cyangwa guteka) ukoresheje imiti kugirango ukure igice cya hemicellulose mumashanyarazi.Lignin ni nkeya cyangwa hafi ya yose idashonga, ariko urwego rwimitsi rworoshe.Nyuma yibyo, uruganda rwa disiki rukoreshwa nyuma yubuvuzi bwo gusya ibiti byoroheje (cyangwa ibyatsi byatsi) kugirango utandukane fibre mumashanyarazi, bita imiti yimiti (CMP).
Imashini ya knotter ya kabili ikoreshwa muburyo bwo gutema ibiti, imigano, imigozi, ibyatsi byumuceri nibindi bikoresho bibisi.Irashobora gutunganya mu buryo butaziguye ibikoresho fatizo muri fibre ya velheti, kandi irashobora guhindurwa muburyo butunganijwe neza.
Imashini ya knotter ya kabili igizwe ahanini nicyumba cya slurry, base, ibikoresho byo kugaburira, ibikoresho byohereza, moteri nkuru, nibindi. Nyuma yuko moteri yihuta binyuze muri kugabanya, igituba gisunikwa mucyumba cyo gusya cyanyuze mu cyuma, hanyuma kirasenyuka. muri fibre ya velheti munsi yo gusya cyane no gusya isahani.Imashini ifite imiterere yoroshye, kuyishyiraho byoroshye no kuyitaho byoroshye.
