Characteristic:
Appearance: Slightly yellow or colorless liquid
Ionic: Non
PH: 6-8
Active ingredients content: 50%Usage:
Dying for wool or cashmere、wool yarn、further etc. animal hair.Performance:
1. SY-7 will decrease the dying temperature for acid dyes, usually the dyeing temperature will decrease from 95-100℃ to 65℃ if other traditional craft keep unchangeable.
2. The dyeing time can be controlled by adjusting the formic acid, the dying is uniform with clean absorption.Reference craft:
Add water and fabric→Add 1-2g/l SY-7( For the dark one, the ratio can be increased to shorten the dyeing time) →Run 10-20 minutes→Add formic acid 0.1-2% to fabric weight( the content of formic acid is 85-88%, many times after dilution) →Add acid dyes→Increase the temperature slowly to 65℃→Heat preservation till clean absorption( usually it is 45-90 minutes) →(Mordant) →Clean.Packing and storage:
125kg/drum, seal airtight.
