What Is Spunmelt Nonwoven

Spunmelt nonwovens are unique fabrics that combine the best of both spunbond and meltblown technologies. The fabric begins with continuous polymer filaments that are first heated and melted, then precisely extruded and stretched, and laid in a random or preset pattern to create a preliminary mesh structure. To enhance the fabric's integrity, the mesh is then bonded by thermal, chemical or mechanical means to form a tough cloth.

Specifically, the spunbond process involves converting molten polymer particles through a spinneret into continuous filaments that are cooled, stretched, laid on a moving carrier to form a base mesh layer, and reinforced by thermal bonding technology to give the fabric excellent strength and tensile properties.

The meltblown process goes a step further and sprays the molten polymer through a tiny nozzle into a high-speed airflow at extremely high speed, instantly breaking it into ultra-fine microfibers that lightly deposit on a collection device to form a soft, fine-fiber mesh. Meltblown fabrics have demonstrated excellent performance in the field of filtration with their delicate fiber structure and large surface area.

When spunbond and meltblown technologies complement each other and work together in the production of non-woven fabrics, spunmelt non-woven fabrics are born. It cleverly combines the strength of spunbond fabrics with the softness and delicacy of meltblown fabrics, which not only ensures the durability of the material but also gives it excellent soft touch and filtering ability. Therefore, spunmelt non-woven fabrics are widely used in medical protection (surgical gowns, masks, etc.), personal hygiene (diapers, sanitary napkins) and industrial fields (filters, insulation materials, etc.), becoming an indispensable and important material in many fields.
