Nibwira ko twese twigeze twumva imyenda y'ubwoya bw'urukwavu mubuzima bwacu, ariko hari icyo uzi ku myenda y'ubwoya bw'urukwavu? Uyu munsi, nzaza hamwe nawe kubyumva, ni izihe ngaruka mbi zimyenda yimisatsi yinkwavu, kimwe n imyenda yimisatsi yinkwavu izabura umusatsi? Kurikiza ubwanditsi tuza kubyiga.
Ni izihe ngaruka mbi z'imyenda y'urukwavu?
1. urukwavu rw'imyenda y'urukwavu ni rugufi kuruta ubwoya, imbaraga zo gufata hagati ya fibre ni mbi cyane.
2. ishati yimisatsi yinkwavu nubundi buryo bwimyenda muguhuza hafi no guterana amagambo buri gihe, byoroshye kumena umusatsi. Ntabwo kandi ari byiza kwambara imyenda yubwoya bwurukwavu icyarimwe n imyenda ya fibre fibre ya sintetike.
Urukwavu rw'ubwoya bw'urukwavu rusuka umusatsi?
Impamvu nyamukuru ituma umusatsi wurukwavu ugwa ni ukubera ko umunzani wumusatsi wurukwavu uri kumurongo umwe wimirongo isa na tile imeze nka oblique, ingero yikigereranyo ni nto cyane, ubuso buringaniye buringaniye, coefficente yo kumanuka no kugaruka ni nto cyane , fibre iragabanuka gake, nizindi fibre ikikije ifata imbaraga, guterana ni bito, byoroshye kunyerera hejuru yigitambara bigahinduka umusatsi waguye. Muri icyo gihe, fibre yinkwavu zifite urukwavu rwa pith, kandi imbaraga zazo ni nke, kuburyo zikunda kuvunika no kugwa mugihe cyo kwambara no gukaraba. Kugirango ugumane uburyo bworoshye kandi bworoshye bwibicuruzwa byubwoya bwurukwavu, guhinduranya umugozi muri rusange ni bito kandi imiterere yimyenda irekuye, bityo nanone byoroshye gutakaza umusatsi.
