Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production equipment, in particular to a novel non-woven fabric upper stretcher. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics and needle-punched cotton, are made of directional or random fibers. They are called cloth because of their appearance and certain properties. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. For example, polypropylene pellets are mostly used as raw materials, and are produced by a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing and winding. During the spinning process, a stretching device is required to draw the resin into a filament. The current stretching device has poor stretching transmission stability, and due to the lack of integrity of the stretching device and the lack of internal closure, it is easy to affect the drawing effect, resulting in uneven drawing fineness and insufficient controllability of drawing quality.
