Orientation and structure development in melt-spun Nylon-6 fibres

A network model is applied to describe the deformation behaviour of melt-spun Nylon-6 fibres obtained at different spinning and drawing conditions. The network draw ratio is determined from analysis of true stress-strain curves and correlated with fibre orientation. From this analysis it appears that the deformation behaviour of Nylon-6 fibres adheres to a pseudo-affine mechanism. The results are discussed in terms of the semicrystalline nature of Nylon-6 fibres. By means of on-line birefringence measurements, wide angle X-ray scattering (WAXS) and solid-state NMR, it is shown that the crystalline and amorphous phases in Nylon-6 respond in a different way to network deformation. In the spin line, an affine (rubber-like) deformation mechanism is observed and this rubber-like network behaviour is transferred to the amorphous phase. After winding and conditioning of the spun fibres, a crystalline phase with relatively high orientation is formed which deforms according to a pseudo-affine mechanism upon further stretching.     

Grafting of Nylon-6, 6 on Cellulose Acetate

Studies on Impact Toughening and Thermal Properties of Nylon-6/LDPE-g-MAH Blends

Polyamide (PA)-6 is an engineering thermoplastic. It finds its application in electrical, mechanical, and automotive parts due to its very high processing and excellent barrier properties to oils. Unfortunately, Nylon-6 (Ny6) is relatively high priced, has poor impact strength, particularly when notched, and poor dimensional stability as well as poor barrier properties to moisture, which limits its applicability. On the other hand, due to low cost, low coefficient of friction, lightweight, high strength, high barrier properties to moisture, good optical properties, and ease of processing, low density polyethylene (LDPE) is an ideal material to incorporate with Polyamide-6 for film, container, and many engineering applications. The present study deals with the preparation of Nylon-6 and modified LDPE (MLDPE) blends, varying the MLDPE concentration from 0 to 50 wt%. The objective of this study is to find the effect of maleic-anhydride grafted low-density polyethylaene on various mechanical properties such as tensile, impact, and flexural properties of Nylon-6. There is a decrease in tensile and flexural properties, the notched Izod impact strength increased greatly when the MLDPE content was 20%. It includes the study the effect of MLDPE on thermal properties and morphological properties of Nylon-6. The morphology of PA/MLDPE blends showed dispersed particle in the polymeric matrix.     

RIM-pultrusion of nylon-6 and rubber-toughened nylon-6 composites

Unidirectionally reinforced thermoplastic composites of Nylon-6 and polypropylene oxide-Nylon-6 block copolymers have been prepared by the reaction injection molding (RIM)-pultrusion process. This process takes advantage of both the RIM and the pultrusion techniques, while avoiding their inherent shortcomings. It also represents a novel way of incorporating toughening rubber domains into a thermoplastic composite. The composites produced exhibit excellent mechanical integrity with essentially zero void content. The chemical and physical states of the composites produced by the process were probed in terms of mechanical relaxation behavior using a dynamic mechanical spectrometer. Due to the simultaneous occurrence of both polymerization and crystallization processes in the reacting system, the resulting material is in a thermodynamically nonequilibrium state. An annealing effect is shown to correspond structurally to an increase in matrix crystallinity and the degree of phase separation, Izod impact tests were used to compare Nylon-6 and rubber-toughened Nylon-6 RIM-pultruded composites. The potential of secondary processing was, demonstrated by compression molding of the RIM-pultruded composite rods.     

Modification of nylon-6 with semi-or wholly-aromatic polyamides

In this study, flexible Nylon-6 was reinforced by semi-or wholly-aromatic polyamides; poly(m-phenylene isophthalamide) (PmIA), poly(4,4′-diphenylmethane terephthalamide) (PMA), and poly(4,4′-diphenylsulfone terephthalamide) (PSA). Various high molecular weight block copolyamides were synthesized by solution polymerization using p-aminophenylacetic acid (p-APA) as a coupling agent. Their thermal properties have shown that the block copolyamides exhibit higher T_g and T_m, and better thermal stability than those of Nylon-6, especially PmIA modified Nylon-6. The order of their thermal properties of aromatic modified Nylon-6 copolyamides is PmIA > PMA > PSA. Moreover, the T_g and T_m of multiblock copolyamides are higher than those of triblock copolyamides. From the wide-angle X-ray diffraction pattern, it is found that the triblock copolyamides have two diffraction peaks, i.e., 2θ = 20.5° and 24°. However, the multiblock has only one peak at 2θ = 20°, indicating a different crystal structure for multiblock copolyamides. For the mechanical properties, it is found that the multiblock copolyamides have a more significant reinforcing effect than the triblock copolyamides. Also, the order of the physical properties of aromatic modified Nylon-6 copolyamides, such as tensile strength, is PmIA > PMA > PSA, but for the elongation PSA > PMA > PmIA.
