Abstract:

In order to tackle the whiteness declination of polyamide 6 fabric after prolonged light exposure, methyl methacrylate (MMA) was grafted onto polyamide 6 (PA6) via hydrogen peroxide/ascorbic acid(H2O2/H2A) as initiator. The effects of grafting time, grafting temperature, initiator and monomer concentration on grafting rate were studied, and the micro morphology, chemical structure, whiteness and wearability of the grafted fabric were characterized. The optimal process conditions were identified as follows: grafting temperature 70 ℃, grafting time 60 min, initiator H2O2/H2A mass fraction 30%, MMA concentration 1.5 mol/L. The fabric surface became rough after grafting with small granular materials. The whiteness index of the modified fabric increased from the previous 58.6 to 70.53 after UV irradiation for 8 h, showing excellent light resistance. The stiffness index of the modified fabric increased from 10.7 to 23.6, and the smoothness increased from 71.7 to 80.3, both contributing to good wearability.

Key words: polyamide 6 fabric, surface modification, initiation system, grafting process, light resistance, wearability, whiteness
