Abstract: This article studied the influence of nano-TiO_2 and nano-SiO_2 on the color of Argazol Red BF-DS,Argazol Yellow BF-3R and Argazol Blue BF-R anti-crease dyed cotton fabrics.The results indicated that the addition of nano-TiO_2 influenced the color of fabric dyed with Argazol yellow BF-3R more than with the other two dyes.At the same time,K/S values of fabrics dyed with the above dyestuffs showed no increase.The addition of nano-SiO_2 brought a greater influence on the color of fabric dyed with Argazol Red BF-DS,but no influence on the color of fabrics dyed with the other two. Meanwhile the K/S values of fabrics dyed with the above dyestuffs decreased slightly.
