The viscosity of PA6 chips (polyamide 6 chips) is an important physical property that affects the fluidity and processing performance of chips in a molten state. For weaving fishing nets, The relationship between the viscosity of PA6 slices and the quality of fishing nets can be explained from the following aspects:

    1.  Fiber strength and toughness : PA6 chips with higher viscosity are more likely to form a uniform fiber structure during the melt spinning process. This uniform fiber structure means that the strength and toughness of the fibers are higher, thereby enhancing the durability and tensile strength of the fishing net.

    2. Mesh Uniformity : High viscosity PA6 chips can better maintain the shape and size stability of fibers during the weaving process, which helps to form a fishing net with uniform mesh and consistent size. A uniform mesh not only improves the appearance quality of the fishing net, but also helps to enhance its performance during the fishing process.

    3. Wear resistance and corrosion resistance : High viscosity PA6 chips may contain more long-chain molecules, which can enhance the crystallinity and intermolecular interactions of polymers, thereby improving the wear resistance and corrosion resistance of fishing nets. This is particularly important for fishing nets used in marine environments, as they need to withstand prolonged friction and corrosion.

    4.  Processing Performance : Although high viscosity may pose certain challenges to processing (such as requiring higher processing temperatures and pressures), appropriate adjustment and optimization of processing parameters can ensure smooth melt spinning and weaving of high viscosity PA6 chips.

    However, it should be pointed out that higher viscosity is not necessarily better. Excessive viscosity may lead to difficulties in processing, increased energy consumption, and unstable product quality. Therefore, when selecting the viscosity of PA6 slices, it is necessary to comprehensively consider the specific use of fishing nets, processing conditions, and quality requirements.

    In addition, the quality of fishing nets is also affected by other factors, such as the purity of slices, spinning process, weaving technology, post-treatment process, etc. Therefore, when improving the quality of fishing nets, it is necessary to comprehensively consider multiple factors and conduct comprehensive optimization.
