Recycled LMF
Recycled LMF 2D/4
Low melt fibre 2D/4D Recycled
Low melting fibre is a kind of bicomponent polyester staple fibre with sheath-core structure. This composite fibre features a smart two-layer design where a low-temperature bonding sheath envelopes a resilient, supportive core.
The moment heat is applied, the sheath gently melts and fuses, while the core remains firm — delivering soft bonding on the outside and reliable strength at the center.
Developed with a reduced-VOC profile(low emissions profile), this low melt fibre helps manufacturers meet stringent odor and emissions specifications.
In addition, its BPA-free formulation meets global safety expectations for skin-contact textiles, infant products, and hygiene materials, offering additional reassurance for brands and manufacturers prioritising material safety.
What’s more, our composite low melt fibre delivers exceptional bonding efficiency, a uniform web structure, and superior thermal stability—making it an essential component for modern nonwoven production.
With a low melting point (110–130°C), it offers highly efficient heat-bonding performance and provides strong adhesion when combined with hollow, solid, or other fibres, functioning as an effective alternative to chemical adhesives.
