1. kuongorora zvinhu
PP jira risiri-rakarukwa: Iyo fiber inoshandiswa kugadzirwa isina-yakarukwa machira ndeye polypropylene, inova yekugadzira fiber inowanikwa nekupolymerization yepropylene.
Mucheka wepolester usiri wakarukwa: fiber inoshandiswa kugadzira machira asiri akarukwa ipolyester faibha, iri faibha yekugadzira inowanikwa nekuruka polyester yakanyungudutswa kubva kuorganic dibasic acid uye diol.
2. Different densities
PP jira risiri rakarukwa: Density yaro ingori 0.91g/cm3, inova ndiyo yakareruka siyana pakati pezvakajairwa kemikari fiber.
Polyester nonwoven fabric: Kana polyester iri amorphous zvachose, density yayo i1.333g/cm3.
3. Kusiyana kwechiedza chekudzivirira
PP isiri-yakarukwa jira: kushomeka mwenje kuramba, insolation kuramba, kuchembera nyore uye brittle kurasikirwa.
Polyester isina-yakarukwa jira: yakanaka mwenje kuramba, chete 60% simba kurasikirwa mushure me600h chiedza chezuva.
4. Kusiyana kwemafuta ekupisa
PP isina-yakarukwa jira: kuderera kwekushisa kugadzikana, kusingamiri kune ironing.
Polyester isiri-yakarukwa jira: yakanaka kupisa kupisa, nzvimbo yekunyunguduka inosvika 255 ℃, uye yakagadzikana chimiro pasi peakasiyana ekupedzisira-kushandiswa mamiriro.
5, akasiyana alkali kuramba
Polypropylene jira risiri rakarukwa: Polypropylene ine yakanaka makemikari kuramba, uye kunze kweiyo concentrated caustic soda, polypropylene ine yakanaka alkali kuramba.
Polyester isiri-yakarukwa jira: Polyester ine kushomeka kwealkali kuramba, iyo inogona kukuvadza faibha painopindirana neyakaomeswa alkali patembiricha yekamuri uye inonatsa alkali pakupisa kwakanyanya.Inongogadzikana chete kudzikisa alkali kana alkali isina simba pakupisa kwakadzika.
