Zvakanakira pasi uye feather sechinhu chekuzadza:

1. Yakanaka thermal insulation: Pasi panogona kuita mhepo pakati peminhenga yakanaka, kudzivirira kurasikirwa nekupisa uye kuchengetedza muviri unodziya.Kuenzaniswa nezvimwe zvinhu zvekuzadza, pasi kune zvirinani thermal insulation performance.2. Huremu uye kugadzikana:Kudzika kune huremu nekuda kwekuderera kwayo, izvo zvisingape vanhu kunzwa kunorema.Panguva imwecheteyo, pasi yakapfava uye yakasununguka, inokwanisa kuenderana nemakumbo emuviri, ichipa ruzivo rwakanaka rwehope.3. Kugara kwakanaka: Pasi ine kusimba kwakanaka, inokwanisa kutsungirira kushandiswa kwenguva refu uye kuchenesa, uye haisi nyore kuremara kana kusakara.4. Kufema kwakanaka: Pasi ine kufema kwakanaka, inokwanisa kuchengetedza kuoma uye mhepo, kudzivirira kukura kwebhakitiriya uye mold, nokudaro kuchengetedza utsanana uye hutano.5. Hushamwari uye hutano: Pasi chinhu chakasikwa chinozadza, chisina zvinhu zvinokuvadza, chisingakuvadze vanhu uye nharaunda, uye chinosangana nezvinodiwa zvezvakatipoteredza uye zvehutano.6. Hupenyu hurefu:Pasi pekuzadza zvinhu zvine hupenyu hurefu, hunokwanisa kushandiswa kwemakore mazhinji pasina kurasikirwa nekushanda kwayo kwekupisa.7. Good compressibility: Pasi pekuzadza zvinhu zvine yakanaka compressibility, inokwanisa kutora nzvimbo diki panguva yekuchengetedza uye yekufambisa.8. Yakanaka elasticity: Pasi pekuzadza zvinhu zvine elasticity yakanaka, inokwanisa kudzoreredza chimiro chayo chepakutanga, kwete kuremara nyore, uye kuchengetedza yakagadzikana yekushandisa ruzivo.

Muchidimbu, pasi uye manhenga (dhadha pasi uye goose pasi) sechinhu chinozadza chine zvakanakira kunaka kwekupisa kwekushisa, kureruka uye kugadzika, kusimba kwakanaka, kufema kwakanaka, kushamwaridzana kwezvakatipoteredza uye hutano, hupenyu hurefu, kusimba kwakanaka, uye kunaka elasticity.Nokudaro, inoshandiswa zvakanyanya mumabhedha, zvipfeko, zvigadzirwa zvekunze, nemimwe minda.
