[0002] Spunbond (spinning fusion) is the most widely used one-step spinning process for forming non-woven fabrics. Spunbond non-woven fabrics are formed by continuous filament fibers, with high production line speed, high product strength and good dimensional stability. The main steps are melt spinning, air flow stretching of nascent fibers, fiber web formation and fiber web shaping. There are three types of fiber web shaping: hot rolling reinforcement method, needle punching reinforcement method and hydroentanglement reinforcement method. Hydroentanglement non-woven fabrics are made by spraying high-pressure fine water flow onto one or more layers of fiber webs to entangle the fibers with each other, thereby reinforcing the fiber web and giving it a certain strength. The resulting fabric is hydroentanglement non-woven fabric.

[0003] The spunlace nonwoven fabric based on the one-step process has a soft feel and good fluffiness, but due to its soft texture, it cannot maintain good tension, and has poor structural stability and low structural strength. Utility Model Content
