Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production. More specifically, the utility model relates to a press pattern structure for non-woven fabrics, which is particularly suitable for disposable spunlace non-woven fabrics. Background Art

[0002] Disposable spunlace non-woven fabrics have the characteristics of softness, air permeability and disposable, so they have been widely used as wiping products in various fields of modern life. However, disposable spunlace non-woven fabrics are not resistant to friction during use, have low longitudinal and transverse strength, poor tensile resistance, low surface friction coefficient, and are prone to fluffing, chipping and low cleaning ability under high-intensity wiping.

[0003] In the prior art, the patent document with the publication number of CN 202463014U discloses a surface embossed non-woven fabric, which has concave-convex structures on the fabric surface of the non-woven fabric, achieving the purpose of accommodating the wiped object, improving the wiping function of the non-woven fabric, and setting a wear-resistant layer and a protective layer. Although the durability and use safety of the non-woven fabric are improved, the softness and disposable properties of the non-woven fabric are lost, and it is not suitable for human body wiping and flushing degradation. Moreover, its press pattern is single and has many edges and corners, resulting in poor wiping effect and easy skin scratching. Summary of the Utility Model

[0004] The utility model provides a non-woven fabric and its press pattern structure to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A non-woven fabric press pattern structure includes a plurality of arranged embossing groove lines. The embossing groove lines are formed by connecting the heads and tails of two semi-circular arc embossing grooves with opposite opening directions to form an S-shaped or reverse S-shaped embossing groove structure. Through this embossing groove line, it can play a role in deformation resistance and elastic recovery when pulling the non-woven fabric, reducing the risk of being broken and reducing or avoiding the risk of damage caused by finger force during the wiping process. And through this embossing groove line, a rounded and angular-free convex structure is formed within the two semi-circular arcs, which cooperates with the embossing groove to store dirt while not easily scratching the skin, improving the wiping effect and use experience.

[0007] The width of the embossing groove line is about 2mm. Through experiments, an embossing line width of 1.5 - 2.5mm can not only ensure the soft comfort of the non-woven fabric but also have a good effect of blocking dirt.

[0008] The connecting line of the centers of the two semi-circular arcs of the embossing groove line has a certain inclination angle, preferably a 45° inclination structure.

[0009] Further preferably, solid pressure points are arranged between the embossing grooves. The raised parts between the embossing grooves of the non-woven fabric are compacted by the solid pressure points to form a sunken area, which cooperates with the sunken area formed by the embossing grooves to jointly form a space for storing dirt, thereby improving the wiping effect.

[0010] As a further preferred solution, the non-woven fabric embossing pattern structure further includes a compacted edge located at the edge of the non-woven fabric. Through the design of the compacted edge, when the non-woven fabrics are stacked, a certain gap is formed between adjacent non-woven fabrics at the edge, which is convenient for extraction, and the strength of the non-woven fabric edge is improved, reducing or avoiding the risk of tearing from the edge.

[0011] A non-woven fabric includes at least one layer of non-woven fabric layer, and the above-mentioned non-woven fabric embossing pattern structure is provided on each non-woven fabric layer.

[0012] When the non-woven fabric adopts two or more non-woven fabric layers, the non-woven fabric layers are press-connected and compounded through solid pressure points and / or compacted edges.

[0013] Through compounding, on the one hand, it plays a role in connecting each layer, making the connection between the layers reliable. On the other hand, deeper depressions are formed at the solid pressure points, improving the dirt storage capacity, and voids are formed between the embossing grooves of each layer for guiding flow, absorbing water, and storing dirt, improving the use effect.

[0014] Among the compounded non-woven fabric layers, at least one layer of the embossing grooves on one non-woven fabric layer is misaligned with or the arrangement direction intersects with the embossing grooves of other layers to improve the tensile strength and use strength of the non-woven fabric in all directions.

[0015] The utility model has the characteristics of simple structure, strong practicability, and good use effect, and is worthy of wide promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
