Makhalidwe a disperse dyes:

Mosiyana ndi mitundu ina yambiri ya utoto, utoto wobalalika susungunuka m'madzi kuposa utoto wina monga utoto wa asidi. Choncho, utoto wobalalitsa umagwiritsidwa ntchito kwambiri popangira madzi osambira.Tamol NNzimagwira ntchito bwino pamene utoto ukuchitika pa kutentha kwambiri. Mwachindunji, mayankho ozungulira 120 ° C mpaka 130 ° C amapereka ntchito yabwino kwambiri yobalalitsira utoto, kuwapangitsa kukhala wogawanika kwambiri komanso wopatsa chidwi, pomweTamol NNkungapangitse mitundu yosiyana komanso yocheperako pa kutentha kochepa.

Kodi utoto wa disperse umagwiritsidwa ntchito bwanji?Tamol NN

Chifukwa cha mankhwala ake komanso momwe zinthu zilili pamwambapa, utoto womwazikana umagwiritsidwa ntchito popaka utoto wopangidwa monga poliyesitala, nayiloni, acrylic, ndi acetate. Mitundu yambiri ya polyester ndi ya hydrophobic ndipo ilibe ma ionic, zomwe zimapangitsa kuti zikhale zosatheka kukongoletsa ndi china chilichonse kupatula utoto wobalalitsa.

Kuphatikiza apo, ulusi wa poliyesitala sumakula pa kutentha kwanthawi zonse ngakhale utamizidwa m'madzi osambira, zomwe zimapangitsa kuti mamolekyu a utoto azilumikizana ndi zinthuzo. Ngakhale pakatentha kwambiri (100°C), utoto wa poliyesitala umakhala ndi vuto.

Chifukwa chake, popaka poliyesitala, utoto wobalalitsa umagwiritsidwa ntchito popaka madzi osambira pa kutentha kwa madigiri 20 mpaka 30 kuposa kuwira kwa madzi osambira. Utoto wobalalitsa umadziwika kuti umasunga umphumphu wawo wam'maselo pa kutentha kwakukulu komwe kumafunikira popanga ma polyesters. Pazifukwa zomwezo utoto wobalalitsa umagwiritsidwa ntchito popaka ma polyesters, amagwiritsidwanso ntchito popaka zinthu zina zosapanga ionic. Mfundo yakuti utoto wobalalitsa ulibe cationic kapena anionic tendencies mwina ndi katundu wodziwika kwambiri wa utoto wobalalitsa.

Utoto wa Disperse utha kugwiritsidwanso ntchito mu utomoni ndi mapulasitiki pazifukwa zopaka utoto wamba.
