  • Nylon 6 - an overview | ScienceDirect Topics
    Nylon 6 is produced by ring-opening chain growth polymerization of caprolactam in the presence of water vapor and an acid catalyst at the melt After removal of water and acid, the nylon 6 is melt spun at 250°–260°C into fibers Nylon 6,6 is prepared by step growth polymerization of hexamethylene diamine and adipic acid After drying, the
  • Nylon Polymer - an overview | ScienceDirect Topics
    Nylon 6 and nylon 6 6 fibres have excellent abrasion resistance Both the fibres also offer outstanding flex fatigue behaviour under a high degree of bending strain In abrasion resistance both nylon 6 and nylon 6 6 fibres surpass virtually all other fibres except high molecular weight gel-spun polyethylene Apart from unique abrasion and flex
  • Chemical Recycling Processes of Nylon 6 to Caprolactam: Review and . . .
    The chemical recycling of polyamides has been investigated since the early 1960s According to Coates' and Getzler's (2020) review of chemical recycling, polyamide 6 (PA6) is an ideal candidate for chemical depolymerization as it is neither thermodynamically nor kinetically limited [16]
  • A Bio-derived Char Forming Flame Retardant Additive for Nylon 6 Based . . .
    Nylon 6 and Nylon 6 blends containing TA had absorption in similar region However, Nylon 6 containing TAT had much higher absorbance in 2400 - 2200 cm-1 region (corresponding to carbon dioxide) and broader IR absorption peaks below 1500cm-1 region Carbon dioxide is a non-flammable gas which often contributes to diluting the gas phase in the
  • Interlaminar shear properties of carbon fiber nylon 6 composites . . .
    After mutual entanglement of graphene oxide-modified waterborne polyurethane and nylon 6 resin molecular chains, decreased distance between molecular chains and increased cross-linking density result in stronger intermolecular forces Higher graphene oxide content improves bonding properties between nylon 6 resin and fibers, leading to greater interlayer shear strength in CF PA6 resin composites
  • The crystallization kinetics of Nylon 6 6T and Nylon 66 6T copolymers
    As 6T % over 10 mol%, all Nylon 6 6T transferred from α-form to γ-form The T m of Nylon 6 6T decreased as the amount of 6T increased The crystallization rate k dropped greatly when the 6T in Nylon 6 6T is over 7 mol% Nylon 66 6T showed little crystalline difference as 6T % varied from 0 to 30 mol% The T m of Nylon 66 6T remained constant, proving Nylon 66 6T is isomorphous
  • Biodegradation of polyamide 6 by Lysinibacillus sp, Alcaligene faecalis . . .
    Polyamide 6 (PA6, polycaprolactam, Nylon 6) is a thermoplastic polymer widely used in construction, automotive, packaging, etc It is a semi-crystalline polymer known for its good mechanical properties, and chemical, and thermal stability, with a low price, compared to the other polyamides PA6 can be synthesized by anionic polymerization of ε
  • Environmental analysis of nylon 6,6 production from gamma-valerolactone . . .
    The nylon 6,6 production in the Saemangeum can effectively reduce the GWP (61%) and FRS (67%) compared to the conventional nylon 6,6 production Furthermore, if the GWP of the two materials used in the production of nylon 6,6 (HMDA, NaOH) can be reduced by 50%, the GWP per kilogram of nylon 6,6 produced will be reduced by 43% (1 91 kg CO 2 eq )
