The Production Principles of Nonwoven Fabrics

Nonwoven fabrics are primarily produced using four methods: mechanical processing, meltblowing, wet processing, and needlepunching. Mechanical processing is the most widely used method in the nonwoven fabric production process. It is produced through processes such as spunbonding, web forming, and thermoforming. Meltblowing uses high-temperature melted plastic and sprays it onto a web to form a nonwoven fabric. Wet processing involves mixing, stirring, settling, or rotating fibers in water, oil, or a suspension. Needlepunching involves using a specialized needlepunch machine to create a nonwoven fabric by needlepunching multiple layers of fiber webs.
