Paunenge uchibvisa triacetate / polyacrylonitrile, polyester / polyacrylonitrile, uye polyester / cellulose yakasanganiswa machira, mutakuri akakodzera uye kwete-ionic detergent inofanira kuwedzerwa.

Kufunga nezvekugadzira

7.1 Jira rinofanirwa kuongororwa sampuli risati rasvuura kana kugadzirisa mumvuri.
7.2 Kugeza (mvura inotonhora kana inopisa) inofanira kusimbiswa mushure mekunge jira rabviswa.
7.3 Kubvisa kunofanirwa kuve kwenguva pfupi uye kunofanirwa kudzokororwa kana zvichidikanwa.
7.4 Pakubvisa, mamiriro ekushisa uye ekuwedzera anofanirwa kudzorwa zvakanyanya zvichienderana nehunhu hwedhayi pachayo, senge oxidation resistance, alkali resistance, uye chlorine bleaching resistance. Kuti udzivise kuwanda kwekuwedzera kwekuwedzera kana kutadza kutonga tembiricha, zvichikonzera kupepeta zvakanyanya kana kupepeta. Kana zvichidikanwa, nzira yacho inofanira kusarudzwa nekubatana.
7.5 Kana jira racho rabviswa zvishoma, zvinotevera zvichaitika:
7.5.1 Kurapa kwakadzika kwemavara edhayi, mumvuri wedhayi haungashanduki zvakanyanya, kudzika kwemavara chete kuchachinja. Kana mamiriro ekubvisa mavara akave nehunyanzvi, anogona kuzadzisa zvizere zvinodiwa zvemuenzaniso wemavara;
7.5.2 Kana jira rakadhayiwa nemavara maviri kana anopfuura ane maitiro akafanana akabviswa zvishoma, shanduko yemumvuri idiki. Nemhaka yokuti dhayi inongobviswa kune imwe dhigirii, jira rakabviswa richaonekwa chete Shanduko mukudzika.
7.5.3 Pakurapa machira ekudhaya ane dhayi akasiyana-siyana mukudzika kwemavara, zvinowanzodikanwa kubvisa dhayi uye kudhayiwa zvakare.
