This is a special polyester fibre with a core which, like all polyester, melts at 255°C, and a sheath made from a special polyester polymer with a 110°C melting point. This fibre is added to a nonwoven at a specific ratio and quickly heated to produce hardening due to the fibres bonding to each other. In contrast to the conventional method of acrylic resin spraying, the product remains a single-type article and the hardness of the nonwoven can be easily adjusted according to percentage of bonded fibre used. Different materials can also be used such as natural fibres. We can supply low melting fibres in white or black at different titers and melt temperatures.
