Embodiment
[0035] 1. Silk home textile fabrics (dyed fabrics) are treated with tea polyphenols alone
[0036] Finishing: TP-Rf 5.0% (o.w.f), temperature 68°C, time 60min, add HAc to adjust the pH value to 4.0, bath ratio 1:20.
[0037] Color: Slightly altered from original color.
[0038] After testing: formaldehyde removal rate: 68.14%.
[0039] 2. Heavy crepe smoke gray
[0040] Finishing: TP-Rf 8.0% (o.w.f), temperature 72°C, time 55min, add NaHCO 3 Adjust the pH value to 8.5-9, and the bath ratio is 1:30.
[0041] Complexation: ferrous sulfate 4.0% (o.w.f), temperature 68°C, time 35min.
[0042] Color: Smoke Gray.
[0043] After testing: formaldehyde removal rate: 81.23%.
[0044] 3. Plain crepe satin, apricot color, tea polyphenols are arranged separately
[0045] Finishing: TP-Rf 10.0% (o.w.f), temperature 75°C, time 50min, add HAc to adjust the pH value to 6.0, bath ratio 1:40.
[0046] Complexation: rare earth 5.0% (o.w.f), temperature 70°C, time 30min.
[0047] Color: A...
