Umbala walolu hlobo lwendwangu ungenziwa ngendlela oyifisa ngayo.Yenziwe nge-polyester engu-65% kanye ne-35% ukotini.
Iphuzu lokuncibilika le-polyester liseduze nalelo le-polyamide, lisukela ku-250 kuya ku-300°C.Imicu ye-polyester ishwabana elangabini futhi inyibilike, kushiye insalela emnyama eqinile.Indwangu ivutha ngephunga elinamandla, eliphunga.Ukusetha ukushisa kwemicu ye-polyester, akugcini nje ukuzinzisa usayizi nokuma kodwa futhi kuthuthukisa ukumelana nokushwabana kwemicu.Imicu kakotini iyimicu yemvelo engenalutho;athambile, apholile, aziwa ngokuthi imicu ephefumulayo futhi ayamunca.Imicu kakotini ingabamba amanzi izikhathi ezingama-24-27 isisindo sazo.Ziqinile, zimunca udayi futhi zingamelana nokuguga kokuhuzuka kanye nezinga lokushisa eliphezulu.Ngezwi elilodwa, ukotini ukhululekile.Njengoba ukotini imibimbi, ukuyixuba ne-polyester noma ukusebenzisa isiphetho saphakade kunikeza izakhiwo ezifanele ezembatho zikakotini.Imicu kakotini ivamise ukuhlanganiswa neminye imicu efana nenayiloni, ilineni, uvolo, kanye ne-polyester, ukuze kuzuzwe izici ezinhle kakhulu zefiber ngayinye.
