FDY, shinda yakazara, shinda yakanyatsodhonzwa. Iyo shinda inomonereka ine yakatarisa yakakwirira uye yepakati crystallinity inogona kuwanikwa nekuunza kutambanudza maitiro mukuita kuruka, inova shinda yakakwevedzwa zvizere. Conventional Polyester uye naironi yakazara sirika yakatambanudzwa, ikemikari fiber filament. Machira eFDY ane kutsetseka, kupfava uye anowanzoshandiswa kugadzira machira esirika. Inoshandiswa zvakanyanya muzvipfeko uye machira epamba.

FDY inonyanya kushandiswa musilika uye mamwe machira, inonzwa yakatsetseka uye yakapfava, DTY yakaderera elastic sirika uye DTY network sirika inowanzoshandiswa mumachira emitambo. FDY inonyanya kushandiswa mune zvipfeko uye machira indasitiri; DTY chinhu chakanakira kurukwa (weft knitting, warp knitting) kana kuruka muchina. Inokodzera kugadzirwa kwembatya machira (akadai masutu, hembe), zvekurara (senge quilt, bedspread, mosquito net) uye zvinhu zvekushongedza (zvakadai sejira reketeni, jira rejecha, jira remadziro, mota yemukati yekushongedza jira). Sirika yakanaka denier (kunyanya iyo mashizha matatu-yakakosha sirika) inonyanya kukodzera Kutevedzera silika jira, gobvu denier sirika anogona kuita makushe-akafanana jira.
