Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Synthetic fibers (British English: synthetic fibres) ndiwo mafirita akagadzirwa nevanhu nekugadzirwa kwemakemikari, kusiyana nemafirita echisikigo ayo vanhu vanowana kubva kuzvisikwa zvipenyu zvine shanduko shoma kana kusava nemakemikari. Iwo mugumisiro wokutsvakurudza kwakakura kwakaitwa nemasayendisiti kuti avandudze micheka yemhuka nemicheka yemiti inowanikwa zvakasikwa. Kazhinji, micheka yokugadzira zvinhu inogadzirwa nokuisa zvinhu zvinogadzira micheka mumakona, zvichiita kuti pave nemucheka. Mafuta aya anonzi ma synthetic kana kuti ma artificial fibers. Ma synthetic fibers anogadzirwa nenzira inozivikanwa se polymerisation iyo inosanganisira kubatanidza monomers kuti iite cheni refu kana kuti polymer. Izwi rokuti polymer rinobva mu Greek prefix "poly" zvinoreva kuti "vakawanda" uye suffix "mer" zvinoreva kuti "zvikamu zviduku". Muenzaniso ndiRayon, Nylon uye Polyester.  Mubvunzo: Chii chinoshandiswa kupinza zvinhu zvinoumba faibha?
