Surface modification of poly(ethylene terephthalate) fibers via controlled radical graft polymerization

Abstract

Functional chemical modifications on poly(ethylene terephthalate) (PET) fibers via radical graft polymerization could be controlled by managing mutual interactions and affinities between different components in the grafting reaction system. Hansen solubility parameters was used as a tool to quantify affinities of related agents and the polymer, and provided reliable results. The latest results proved the practicality of using Hansen solubility parameters in controlling radical graft polymerizations on surface modifications of PET fibers. Four different monomers with different hydrophilic properties in different solvent and initiator systems were examined, and results confirmed that interactions of initiator‐PET, initiator‐solvent, monomer‐PET, monomer‐solvent, and monomer‐initiator play important roles in determining the grafting reaction efficiency. Results revealed that for the selected grafting systems studied, hydrophilic monomers presented overall favoring affinities toward PET leading to higher grafting yields compared to hydrophobic monomers. The results have instructive impact to commercial applications. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45990.

Disinfectant Performance of a Chlorine Regenerable Antibacterial Microfiber Fabric as a Reusable Wiper

“…The overall reaction indicates that BPO could initiate the radical graft polymerization reaction of ADMH on the fabrics, confirming the reaction reported in the literature [28,30,31]. After ten washes, the grafted ADMH survived the hard friction and laundry conditions and remained on the surface of the fabric, due to stable covalent bonding.…”

“…Halamine structures, in combination with other antibacterial agents, have been grafted onto fabrics to provide unique antimicrobial properties [29]. However, surface chemical modification of chemically inert polyester fibers was not very successful until a controlled radical graft polymerization process, which can incorporate many hydrophilic and hydrophobic vinyl monomers onto polyester surfaces, was developed recently [28,30,31].…”

“…In this study, a precursor of the biocidal halamine chemical, 3-allyl-5,5-dimethylhydantoin (ADMH), was grafted onto surfaces of polyester fabrics by following the controlled radical polymerization reaction, using a commercial finishing facility [28,30,31] (Figure 1). After chlorination of the treated fabrics in a diluted sodium hypochlorite solution, N–H bonds in the grafted ADMH of the fibers were transformed to biocidal N–Cl bonds [32,33].…”

Hierarchical Porous Recycled PET Nanofibers for High-Efficiency Aerosols and Virus Capturing

“…The solubility parameters between NMP and PET were relatively narrow. NMP is the mainstream post-treatment solvent for PET, 26 while acetone is a typical highly polar solvent. The PET fibers would be swollen during immersion in the NMP/ethanol solvents and the NMP solvent-induced recrystallization occurred.…”

“…Research on hydrophilic modification of PET material includes a variety of modification methods including: hydrophilic coating layer, [6][7] surface radical graft polymerization [8][9] and monomer polymerization. [10][11][12] Hsiao et al 10 presented the physics and kinetics of alkaline hydrolysis of cationic dyeable poly(ethylene terephthalate) (CDPET) and polyethylene glycol (PEG) modified CDPET polymers.…”
