Problems solved by technology

[0005] In the existing preparation process of composite fiber nonwoven fabric, each fiber layer of composite fiber nonwoven fabric is prepared separately. The original structure of the fiber layer is damaged by reinforcement methods such as adhesives, acupuncture, and spunlace, and separation is prone to occur; in addition, the existing composite fiber nonwovens require many processing procedures, which also makes the composite The production efficiency of fiber nonwovens is low

Abstract

The invention discloses a preparation system of a composite fiber non-woven fabric with a gradient distribution structure, and relates to the technical field of non-woven equipment. The preparation system includes a gradient distribution spinning unit and a receiving device; the gradient distribution spinning unit includes at least two groups of spinning devices, and each group of spinning devices is provided with horizontal blowers whose air outlet directions are both left or right The nozzle; the receiving device is arranged on one side of the horizontal blowing nozzle in the air outlet direction, and is used for synchronously receiving the fibers spun by each group of spinning devices through the side of the corresponding receiving mesh curtain. The invention realizes the one-time forming of the composite fiber non-woven fabric through the single-side horizontal blowing design of the spinning device and the gradient distribution design of multiple groups of spinning devices, and can realize the real-time control of the structure distribution of each component of the composite fiber non-woven fabric.

Description

technical field [0001] The invention relates to the technical field of non-woven equipment, in particular to a preparation system of a composite fiber non-woven fabric with a gradient distribution structure. Background technique [0002] Traditional non-woven fabrics are usually divided into single-component fiber non-woven fabrics formed by single-component fibers and composite fiber non-woven fabrics formed by multi-component fibers. Among them, single-component fiber nonwovens are often single-layer structure, and the fiber diameters are basically the same; composite fiber nonwovens are mostly multi-layer composite structures, and the fiber diameters of each layer are different. [0003] In the existing process for preparing composite fiber non-woven fabrics, it is necessary to prepare each fiber layer separately through one-time processing, and then perform acupuncture, hydroentangling, thermal bonding, etc. on the prepared fiber layers through secondary processing. The...
