Description

Technical Field

[0001] The utility model relates to the technical field of fiber preparation, in particular to a traction device for preparing ES fibers. Background Art

[0002] ES fiber is a two-component, low-melting-point, hot-melt fiber composed of polypropylene and polyethylene. The core layer of ES fiber is polypropylene, which acts as the main fiber, while the sheath layer is polyethylene, which acts as a hot-melt adhesive. This structure allows the sheath layer of ES fiber to melt and bond during the heat treatment process, while the core layer remains in a fiber state, thus forming a special thermally bondable composite fiber. The structure and production process of ES fiber are as follows: its core layer is polypropylene, which acts as the main fiber, while the sheath layer is polyethylene, which acts as a hot-melt adhesive. During the production process, ES composite fibers are prepared through processes such as spinning, drawing, and curling, among which curling molding and oven drying and heat setting are the two most critical steps.

[0003] ES fiber has a wide range of applications. Due to its high strength, good elasticity, good porosity, and excellent permeability, ES fiber is commonly used in the production of sanitary materials, thermal insulation fillings, and filter materials. For example, in the production of KN95 masks, ES fiber is used as hot air cotton to improve the mask's filtration efficiency and comfort.

[0004] At present, in the actual application of the traction device for ES fiber preparation, the fiber filaments ejected from the nozzle of the electrospinning equipment enter the receiving device under the action of the traction mechanism. In this process, the thin stream undergoes solvent volatilization, solidification and other processes, and finally deposits on the receiving device to form fibers. However, if the surface tension is too large during the fiber filament traction process, the fiber filaments will break, affecting the fiber preparation. Utility Model Content
