Singano ya Polyester (PET, terylene inamva) inamva nsalu yopanda nsalu yokhala ndi mphamvu zolimba kwambiri, kukana kwamphamvu kwambiri, kukana bwino kwa asidi, kalasi ya chakudya, imodzi mwazinthu zosefera ndalama zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana opangira fumbi. kugwiritsa ntchito (nsalu zosefera fumbi popanga matumba a fumbi).
Zonel Filtech yokhala ndi gulu lodziwa zambiri komanso laluso, ili ndi mizere yamakono yokhomerera singano yophatikizidwa ndi zida zoyambira kalasi yoyamba imapangitsa kuti singano ya polyester imve zosefera kuchokera ku Zonel yokhala ndi mpweya wofanana ndi makulidwe, kulimba kwamphamvu kwambiri, pamwamba posalala komanso kumasula mosavuta fumbi keke, cholimba.
Malinga ndi zochitika zosiyanasiyana ntchito ndi zopempha umuna, poliyesitala fyuluta nsalu akhoza kusankha zosiyanasiyana mapeto mankhwala, monga madzi ndi mafuta othamangitsa, PTFE kuyimitsidwa kusamba, PTFE nembanemba laminated, moto umboni ndi zina zotero kuti apange izi fyuluta nsalu kusonkhanitsa fumbi ndi wangwiro kusefera ntchito.
