Description

Technical Field

[0001] The invention relates to the field of non-woven fabric manufacturing, and in particular to a non-woven fabric manufacturing device with a rubber surface and a process thereof. Background Art

[0002] In the non-woven fabric manufacturing industry, in order to meet specific application requirements, such as increasing the adhesion, sealing or decorative properties of non-woven fabrics, it is often necessary to coat the surface of non-woven fabrics with glue. Traditional non-woven fabric coating equipment often has problems such as uneven coating, serious waste of glue, and low production efficiency. Especially when manufacturing non-woven fabrics with glue surfaces, how to ensure that the glue is evenly distributed on the surface of the non-woven fabric while avoiding adhesion or uneven drying caused by excessive glue has become a technical problem that needs to be solved urgently. Most of the existing glue coating equipment uses a simple glue coating roller to transfer the glue to the non-woven fabric, but this method is often difficult to accurately control the amount and distribution of the glue, resulting in poor gluing effect. In addition, the non-woven fabric after glue coating usually needs to be dried to remove excess solvent and accelerate the curing of the glue, but the existing drying devices often have problems such as high energy consumption and uneven drying, which affects the quality and production efficiency of the product.

[0003] Therefore, in order to solve the above-mentioned problems, a method for manufacturing a non-woven fabric with an adhesive surface is specifically proposed. Summary of the invention
