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¡æ to 65¡æ 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¡úAdd 1-2g/l SY-7( For the dark one, the ratio can be increased to shorten the dyeing time) ¡úRun 10-20 minutes¡úAdd formic acid 0.1-2% to fabric weight( the content of formic acid is 85-88%, many times after dilution) ¡úAdd acid dyes¡úIncrease the temperature slowly to 65¡æ¡úHeat preservation till clean absorption( usually it is 45-90 minutes) ¡ú(Mordant) ¡úClean. Packing and storage: 125kg/drum, seal airtight.
