Ibara ryubwoko bwimyenda irashobora gutegurwa nkuko ubisabwa.Ikozwe muri 65% polyester na pamba 35%.
Ingingo yo gushonga ya polyester yegereye iya polyamide, kuva kuri 250 kugeza 300 ° C.Fibre ya polyester igabanuka kuva kumuriro no gushonga, hasigara ibisigara byumukara.Imyenda yaka numunuko ukomeye, ukaze.Gushyushya fibre ya polyester, ntabwo ihindura ingano nubunini gusa ahubwo binongera imbaraga zo kurwanya iminkanyari.Ipamba y'ipamba ni fibre isanzwe;ziroroshye, zikonje, zizwi nka fibre ihumeka kandi ikurura.Ipamba y'ipamba irashobora gufata amazi inshuro 24-27 z'uburemere bwayo.Birakomeye, bifata irangi kandi birashobora guhagurukira kurwanya abrasion hamwe nubushyuhe bwinshi.Mu ijambo rimwe, ipamba iroroshye.Kubera ko impu zipfunyika, kuyivanga na polyester cyangwa gushira kumurongo uhoraho bitanga imitungo ikwiye kumyenda y'ipamba.Ipamba ya pamba ikunze kuvangwa nizindi fibre nka nylon, imyenda, ubwoya, na polyester, kugirango igere kumiterere myiza ya buri fibre.
