Bleaching process to flax/wool blended yarn with urea peroxide

Bleaching process to wool/flax blended yarn with urea peroxide was carried out.On the basis of studying the bleaching performance influenced by factors such as urea peroxide concentration,bleaching temperature,treatment time and EDTA consumption,the optimal bleaching technology was determined.That were urea peroxide 8 g/L,sodium pyrophosphate 6 g/L,pH value 8,bleaching at 80 ℃ for 80 minutes.Results of performance test indicated that the beaching condition to wool/flax blended yarn with urea peroxide was mild,and having little damage to the yarn,being conducive to environmental protection and following producing.The feasibility of technology was turned out.
