Description

Injection molding mechanism for producing spun-laced non-woven fabric

Technical Field

The utility model relates to the technical field of water jet non-woven fabric injection mechanisms, in particular to an injection molding mechanism for water jet non-woven fabric production.

Background

The spun-laced non-woven fabric is obtained by spraying high-pressure micro water flow onto one or more layers of fiber webs to enable the fibers to be intertwined together, so that the fiber webs are reinforced and have certain strength, and the obtained fabric is the spun-laced non-woven fabric. The fiber raw materials are widely available, and can be terylene, chinlon, polypropylene, viscose, chitin fiber, superfine fiber, tencel, silk, bamboo fiber, wood pulp fiber, alginate fiber and the like. The hydroentangled nonwoven process, known as spunlacing or hydroentanglement, is a nonwoven processing technique. The hydroentangled nonwoven process produces a hydraulic action by the continuous jet of high pressure water streams under which the aligned fibers begin to surge, shift and rearrange and entangle with each other, and the web is consolidated and has certain physical and mechanical properties. The mechanism of the hydroentanglement reinforcement process is that after the fiber web enters a hydroentanglement area through a net supporting curtain, high-pressure water flow forms continuous 'hydro-pins', the hydro-pins are cylindrical and vertically irradiate the fiber web through a hydroentanglement head and a hydro-pin plate; during this process, the fibers are carried from the surface into the web substrate by the hydro-pins and form entanglement; the fiber net is penetrated by the water needle in different directions after the water needle penetrates, so that the fiber net receives the double functions of water columns on the front side and the back side in the whole water needling process, and tangles in different directions are formed, are irregular and achieve the reinforcing effect, and therefore the water-jet non-woven fabric is formed.
