By analysising the crimped deformation processing of PP cigarette filter tow,it is shown that the structure of trilobal cross section has direct connection with the fiber's stiffness, which has a great influence upon the tow's crimped behavior and quality.

Using butyl acrylate (BA), methyl methacrylate (MMA), acrylic acid (AA) and 2-ethythexyl acrylate(2-EHA) as monomers, 2-acrylamido-2-methylpropyl sulfonic acid (AMPS) as emulsible monomer, K_2S_2O_8 as initiator and NaHCO_3 as electrolyte, the acrylate copolymer adhesive emulsion for polypropylene tow of cigarettefilter was prepared by emulsifier-free polymerization.
