Problems solved by technology

This material is only suitable for the production of sewn lining, it cannot be shaped, the process is complicated, and the processing cost is high
In addition, the foaming factory uses this material to set the mold, which consumes a lot of man-hours, and is easy to wrinkle and cause defective products
In addition, the existing non-woven products have many manufacturing processes, high cost, easy to wrinkle, and low efficiency when foaming. For example, the conventional mold setting time is 15 seconds / piece

Abstract

The invention relates to a lining non-woven fabric and a lining cold pressing 2D and 3D forming method thereof. The lining non-woven fabric comprises 5-40 parts of a low-melting-point fiber for shaping and reducing air permeability, 5-40 parts of a low-melting-point fiber for shaping and increasing hardness, 3-10 parts of a black polyester staple fiber and 20-60 parts of a white 2D polyester staple fiber. The preparation method comprises the following steps: short fibers are mixed, opened, carded, laid and needled to form to obtain the non-woven fabric; the non-woven fabric is heated and is conveyed to an oil pressure shaping device, a hydraulic shaping device is used to drive the upper main mold and the lower main mold to be closed, a sub-mold is closed by a peripheral air pressure device, cooling and shaping are carried out, and demoulding is carried out to obtain the lining non-woven fabric. The lining non-woven fabric is not required to be sewn, and the lining non-woven fabric canbe shaped by matching each raw material with a cold pressing 2D and 3D processing technology, so that the lining non-woven fabric can be better attached to a foaming cotton mold, the production efficiency of the foaming cotton is improved, the defective rate of the foaming cotton is reduced, and the lining non-woven fabric can be widely used for foaming automobile seat sponges, so that passengersare more comfortable.

Description

Technical field [0001] The invention relates to the technical field of lining non-woven fabric design, in particular to a lining non-woven fabric and a cold pressing 2D and 3D forming method for the lining. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical netting, and then undergo hydroentangling, needle punching, or hot rolling reinforcement, and finally finishing The resulting non-woven fabric. A new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, and silky soft. It is also a kind of reinforcing material and has a cotton feel. In recent years, non-woven fabrics, as a flexible material production system with high technical content, wide market demand, and a wide range of modern materials industries, are developing at an alarming speed and are known as the...
