摘要

Hydroentanglement (or spunlacing) is a versatile process for bonding nonwoven webs using fine, closely spaced, high velocity jets of water to rearrange and entangle loose arrays of fiberes (webs). Web properties, such as area density, fibre material, the modulus and bending stiffness of the fibres, their length and the friction between the fibres, the method used in producing the web (parallel or cross-laid), all determine the outcome of the process. Hydroentanglement process parameters, such as number of passes, water jet pressure levels, single- and double-sided treatment, need to be optimised to suit the particular web being treated. Here we report the results of an investigation into the effect of various web and processing parameters on the strength properties of hydroentangled fabrics and on the energy consumption of the process. We have measured the modulus and tensiile strength of a number of hydrogentangled fabrics produced from Viscose-PET, PET and Twaron webs. The relationship between fabric strength, the water jet pressure and the hydraulic energy consumption is investigated.
