Madhayi mazhinji akajeka uye anochinja-chinja anobviswa mumusanganiswa.

Shandisa 3% kusvika 5% yeupfu chena uye sipo yeanionic kurapa kwemaminitsi 4O-6O pa80℃ uye pH4. Madhayi akapararira uye ane acid anogona kubviswa kubva mu diacetate/polypropylene fiber, diacetate/wool, diacetate/nylon, nylon/polyurethane, uye nylon textured yarn inodhayiwa neacid.

Shandisa 1-2 g/L sodium chlorite, bika kweawa imwe chete pa pH 3.5, kubvisa madhayi akapararira, ecationic, akananga kana anopindura kubva mumucheka wakasanganiswa wefiber we cellulose/polyacrylonitrile. Pakubvisa machira akasanganiswa etriacetate/polyacrylonitrile, polyester/polyacrylonitrile, uye polyester/cellulose, sipo yakakodzera yekutakura uye isiri ionic inofanira kuwedzerwa.

Zvaunofanira kufunga nezvekugadzira

7.1 Jira rinofanira kuongororwa usati wabvisa jira kana kugadzirisa ruvara rwaro.
7.2 Kusuka (mvura inotonhora kana inopisa) kunofanira kusimbiswa mushure mekunge jira rabviswa.
7.3 Kubvisa bvudzi kunofanira kuitwa kwenguva pfupi uye kunofanira kudzokororwa kana zvichidikanwa.
7.4 Pakubvisa, mamiriro ekupisa uye zvinowedzerwa zvinofanirwa kudzorwa zvakanyanya zvichienderana nehunhu hwedhayi pachayo, zvakaita sekudzivirira oxidation, alkali resistance, uye chlorine bleaching resistance. Kudzivirira kuwanda kwezvinowedzerwa kana kudzora tembiricha zvisina kunaka, zvichikonzera kukwesha kana kukwesha zvakanyanya. Kana zvichidikanwa, maitiro acho anofanira kusarudzwa ne stakeout.
7.5 Kana jira rabviswa zvishoma, zvinotevera zvinoitika:
7.5.1 Pakugadzirisa kudzika kwemavara edhayi, mumvuri wedhayi hauzochinji zvakanyanya, kudzika kwemavara chete ndiko kuchachinja. Kana mamiriro ekubvisa mavara akagadziriswa, inogona kuzadzisa zvizere zvinodiwa nemuenzaniso wemavara;
7.5.2 Kana jira rakapendwa nedhayi mbiri kana kupfuura dzine mashandiro akafanana rikabviswa zvishoma, shanduko yeruvara idiki. Nekuti dhayi inobviswa chete kusvika padanho rimwe chete, jira rakabviswa rinongoonekwa chete. Shanduko dzakadzama.
7.5.3 Pakugadzirisa machira ekudhaya ane mavara akasiyana-siyana, zvinowanzodiwa kubvisa madhayi uye kudhayiwazve.
