I-polyester hollow fiber yinto ehambelana nokusingqongileyo kunye nesixhobo esinokusetyenziswa kwakhona esenziwe ngamalaphu alahliweyo kunye neebhotile zeplastiki ngeenkqubo ezininzi ezinjengokucoca, ukunyibilika kunye nokuzoba. Ukukhuthaza iintsinga zepolyester zinokuphinda zisetyenziswe ngokufanelekileyo kwaye ziphinde zisebenzise izixhobo, ukunciphisa inkunkuma yemithombo kunye nongcoliseko lokusingqongileyo. Ukongeza, ulwakhiwo olungenanto olulodwa luzisa ukugquma okuqinileyo kunye nokuphefumla, kuyenza ibonakale phakathi kweemveliso ezininzi zefiber.
