Stitch-Bonding and Maliwatt Technology
topic
Stitch-bonding machines including Maliwatt and Malimo systems pass fibre webs or yarn layers through a warp knitting zone where a limited number of guide bars stitch through the web with chain or tricot stitch patterns using warp knitting needles and guide bars operating continuously across the full fabric width, creating a stitched-bonded nonwoven with higher tensile strength and dimensional stability than needle bonded or thermally bonded alternatives.
Role
Produces nonwovens with the highest tensile strength and lowest elongation of any nonwoven bonding method by stitching through the fibre web with continuous warp knitting yarn that provides high-tenacity reinforcement without the stiffness of chemical binder, enabling production of strong, flexible nonwovens for geosynthetic reinforcement, roofing substrate, and upholstery backing applications requiring both high strength and fabric drape.
