Njengeyona fiber iphambili eyenziweyo, amalaphu epolyester athatha indawo ebalulekileyo kumzi mveliso welaphu ngenxa yokusebenza kwawo okugqwesileyo kunye nokusebenza okubanzi. Uncedo lwabo lubonakaliswa ikakhulu kule miba ilandelayo.
Okokuqala, amalaphu e-polyester anika ukuxhathisa okukhethekileyo kwe-abrasion. Ulwakhiwo lwazo lwemolekyuli ezidityanisiweyo kunye namandla aphezulu efayibha zonyusa kakhulu ukukrazuka kunye nokuxhathisa kwe-abrasion xa kuthelekiswa nemicu yendalo efana nomqhaphu kunye noboya. Oku kwenza iimveliso zepolyester ukuba zomelele kwaye zifaneleke ngakumbi-usetyenziso oluphezulu olufana nempahla, imithwalo, kunye namalaphu emizi-mveliso.
Okwesibini, amalaphu e-polyester abonisa ukumelana nokushwabana okugqwesileyo kunye nokugcinwa kwemilo. Ukuchacha kwabo okomelela okunwebekayo kubenza bashwabene-baxhathise, bagcine inkangeleko yabo nasemva kokunxiba ixesha elide okanye ukusonga. Le propathi ibenza balungele iimpahla ezifuna inkangeleko ekrwada, enje ngeehempe kunye neesuti, ngelixa zikwanciphisa imfuno yoku-ayina kunye nokuphucula ukusetyenziswa ngokulula.
Ngapha koko, amalaphu e-polyester abonisa ukuchasana kweekhemikhali kunye nokugqwala. Ziyakwazi ukumelana ne-asidi, i-alkalis, kunye ne-oxidants, kwaye azibonakali ngokukhawuleza kwiimpembelelo zendalo, zizenza zilungele ukusetyenziswa okukhethekileyo njengempahla yangaphandle, iintente, kunye nempahla yokukhusela kwimizi-mveliso. I-polyester ikwaqhayisa ngokuchasa ukukhanya okuphezulu xa kuthelekiswa neentsinga zendalo, ukuxhathisa ukufiphala okanye ukonakala phantsi kokukhanya kwelanga ixesha elide.
Ngokwezoqoqosho, ixabiso eliphantsi lemveliso yepolyester kunye nokulula kwemveliso yemizi-mveliso enkulu{0} iyenza ibenexabiso eliphezulu{1}}imathiriyeli ekrwada yelaphu ekrwada. Ngaphaya koko, amalaphu epolyester kulula ukuwacoca, ome ngokukhawuleza, kwaye ashwabene{3}}akanyangeki, aphucula ukusebenza kwawo.
Ngamafutshane, amalaphu epolyester, ngenxa yokunganyangeki kwawo, ukushwabana kwemibimbi, ukuxhathisa kwikhemikhali, kunye neendleko-ukusebenza ngokufanelekileyo, asetyenziswa kakhulu kwimpahla, kwimpahla yasekhaya, nakwizinto ezisetyenziswa kwimizi-mveliso, oko kuwenza abe yimathiriyeli eyimfuneko kushishino lwamalaphu lwangoku.
