fusi conveyor tapoleni i le mea e gaosia o lo o sili ona faaaogaina masani e pei polyester ma nylon vaega se lua. I totonu oi latou, polyester ma nylon ua vaevaeina i ituaiga eseese.

Polyester: Oloa polyester igoa, suafa faasaienisi terephthalate polyethylene ua uma ona diester, faapuupuu o Pete. Polyester ua i ai le lelei o le tetee lelei vevela, laiti deformation, e le faigofie ona mitiia susu, malosi sili. Lea le polyester vulu e tusa ma lona faatinoga uluai, vaevaeina i le malosi sili (ie, ituaiga masani), maualuga modulus shrinkage maualalo, maualalo ituaiga shrinkage, maualalo ituaiga shrinkage.

Nylon: fefaatauaiga nylon igoa, nylon 6 ma nylon 66, nylon vaevaeina i ituaiga e lua. Nylon 6 o igoa faasaienisi polycaprolactam, faapuupuu o PA6, PA66 igoa faasaienisi o adipamide polycaprolactam, faapuupuu PA66. Aoao lelei o nylon o se malosi sili, tetee vaivai o laiti, density maualalo. Ae o le drawback e toe maua le susu maualuga, aafia i aafiaga o le siosiomaga.
