Abstract:
In order to facilitate the industrial production and improve the antkbacterial property of polyester fabrics, the insoluble initiator was emulsified in water to graft 3-allyl-5, 5-dimethyl-hydantoin (ADMH) to polyester fabric. The fabrics before and after grafting were characterized, and the fabrics were chlorinated and subjected to antibacterial testing by pad-cure peocessing according to the AATCC standard. The results show that under the conditions 0.5% initiator can be stabilized and emulsified and then used for fabric finishing; antibacterial monomer is successfully grafted on the fabric surface; compared with the grafting ratio of fabric of 0.046% using rnemulsified initiator, the grafting ratios of polyester fabric using emulsified initiator is greatly improved to 0.489%, and by finishing with crosslinking agent, the grafting ratio is further improved to1.023%. The fabric has the antibacterial ratio to 105 CFU/mL Staphylococcus aureus up to 80%, and the antibacterial ratio of modified polyester finished with crosslinking agent is up to 96%.
Key words: emulsification, initiator, N-halamine antibacterial, grafting, polyester fabric
