摘要

Feather fibers dyed with the weak acid dyes in ultrasonic conditions. Influence of different dyeing time and dyeing temperature on dye uptake and the formaldehyde content was discussed through the multiple linear regression analysis method, respectively. This paper discussed the correlation between dye uptake, the formaldehyde content and dyeing time, dyeing temperature, and established linear regression equation of dye uptake, the formaldehyde content with different dyeing process conditions, respectively. The best dyeing time was 45min and the best dyeing temperature was 80°C, according to the linear regression equation. The experimental results showed that dye uptake could achieve 92.1% and the highest value of the formaldehyde content was 33.09 mg/kg. The linear regression of dye uptake and the formaldehyde content had a high fitting precision and a good predicting ability, which can be of guiding significance to the actual production.
