Current status and developing trend of research on anti-dripping of thermoplastic fibers

Retrospecting the development process of the anti-dripping research on thermoplastic fibers,the paper sums up the present research methods such as copolymerization,blending,grafting and irradiation crosslinking compare their advantages and shortcomings,analyzes the commonly-used anti-dripping mechanisms like tacky effect,carbon-forming and intumescent flame retardance,and propects the developing trend in anti-dripping research.It points out that the irradiation crosslinking has a bright future since it is a cold processing technique characterized by energy conservation,environmental friendliness and easy industrialization.Its application in flame retardant anti-dripping and establishment of anti-dripping theory are worthy subjects for further exploration.
