Uneven dyeing of PET fiber
문제 현상
After PET fiber dyeing, color flowers and color differences appear, and color fastness is poor.
원인 분석
Fiber crystallinity and orientation degree are uneven, causing dye uptake differences; spinning cooling conditions fluctuate; draw ratios are inconsistent.
해결 방법
Stabilize spinning process parameters (temperature, cooling air, speed); control draw ratio consistency; select color masterbatch with good dispersibility.
핵심 요약
PET fiber dyeing uniformity depends on the uniformity of the fiber microstructure.
