柔软整理影响尼龙染色织物增深效应因素分析OA

In order to investigate the effect of finishing process on the color depth of nylon dyed fabrics,acid black 172 and acid yellow GL dyed nylon fabrics were taken as the research objects.The finishing pro-cesses of silicone oil(L-F184)and fluffy softener(E-390)were optimized through orthogonal experiments.The deepening mechanism was analyzed in combination with surface morphology,roughness and reflectance.The results showed that the softening effect of silicone oil finishing agent was better than that of fluffy soften-er,and the deepening effect was more obvious.After finishing,the K/S value of the fabric was increased by 19.6%,the surface roughness Sa value increased from 25.85 μm to 31.85 μm,and the reflectivity of the fab-ric showed a decreasing trend,which indicated that the increase of roughness led to the decrease of light re-flectivity,and the L* value of brightness index also decreased accordingly.In addition,both softeners were low refractive index liquids.The increase in surface roughness worked in synergy with the low refractive index film to reduce the fabric's reflectivity and produce a deepening effect.
