PH value: 6-8

Effective content: 50%

use:

Dyeing of animal hair such as wool or cashmere, wool yarn, and fur.

Features:

Reduce the dyeing temperature of acid dyes, generally reduce the dyeing temperature from 95-100 °C to 65 °C under the traditional process, and adjust the dyeing time by adjusting the amount of formic acid, dyeing evenly, and clean color .

Reference process:

Influent and fiber → add SY-7 dyeing agent 1-2 g / liter (dark color can increase the amount to shorten the dyeing time) → run 10-20 minutes → add fiber weight 0.1-2% formic acid (formic acid content 85-88% → after dilution, add several times, according to the dyeing depth and coloring speed, determine the acid ratio after the sample) → add acid dye → start slowly heating to 65 ° C → keep warm until the color is clean (usually 45- 90 minutes) → (mord dye) → cleaning
