Description

Technical Field

[0001] The utility model belongs to the field of non-woven fabric processing equipment, and more specifically, relates to a production device for transverse elastic non-woven fabric. Background Art

[0002] Non-woven materials are widely used in many fields such as medicine, hygiene, clothing and industry due to their soft texture, good air permeability, uniform structure, and certain strength and elasticity. In specific fields, such as personal care and medical protection, the demand for transverse elastic non-woven fabrics is increasing. This material can better adapt to the curves of the human body and improve wearing comfort and fit.

Since this process only activates the material in the longitudinal direction, the product lacks elasticity in the width direction, which makes it difficult to meet the demand for transverse elasticity in some specific application scenarios.

[0056] Working principle:

[0057] This transversely elastic nonwoven fabric production device includes a frame, a drive assembly, and a roller assembly. The roller assembly is mounted on the frame and driven by the drive assembly. The front roller of the roller assembly consists of a first roller and a second roller. The first roller is positioned above the second roller, and the two rollers cooperate to form a roller gap. The outer circumference of the second roller is provided with a plurality of annular protrusions, and annular grooves are formed between adjacent annular protrusions to apply transverse pressure to the nonwoven fabric.

[0058] Specifically, as the nonwoven fabric passes between the first and second rollers, the annular protrusions, under the action of external forces, compress and stretch the nonwoven surface laterally. The first roller contains an internal water circulation system that uses the circulation of heated water to raise the roller surface temperature, thereby thermoplastically activating the nonwoven material and fixing the fiber structure during the stretching process. After the reciprocating motion of the second roller, the nonwoven fabric passes through the cooling roller assembly for rapid cooling and shaping, achieving lateral elasticity.

[0059] In a further improvement, the first roller is further provided with a plurality of blocking bars, so that the heated water forms a water tank in the first inner cavity. The design of different blocking bars achieves uniform heating and further improves the activation effect.

[0060] The above is only a preferred specific implementation method of the present application; however, the protection scope of the present application is not limited thereto; any technician familiar with the technical field within the technical scope disclosed in the present application, who makes equivalent replacements or changes based on the technical solution and improved ideas of the present application, shall be covered within the protection scope of the present application.
