Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, and more specifically, to an embossed pattern structure for non-woven fabric, which is particularly suitable for flushable spunlace non-woven fabric. Background Art

[0002] Flushable spunlace nonwovens combine softness, breathability, and flushability, making them widely used as wiping products in various areas of modern life. However, flushable spunlace nonwovens are not resistant to friction during use, have low longitudinal and transverse strength, poor tensile strength, and a low surface friction coefficient. They are prone to pilling and shedding under high-intensity wiping, resulting in poor cleaning performance.

[0003] In the prior art, the patent document with the announcement number CN 202463014U discloses a surface embossed non-woven fabric, which has a concave-convex structure on the surface of the non-woven fabric, so as to achieve the purpose of accommodating the wiped object and improve the wiping function of the non-woven fabric, and is provided with a wear-resistant layer and a protective layer. Although the durability and safety of the non-woven fabric are improved, the softness and flushability of the non-woven fabric are lost, and it is not suitable for wiping the human body and is prone to flushing and degradation. In addition, its embossed pattern is single and has many edges and corners, resulting in poor wiping effect and easy scratching of the skin. Utility Model Content

[0004] The utility model provides a non-woven fabric and an embossed pattern structure thereof to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A non-woven fabric embossed pattern structure includes several parallel embossed wavy line groups, each embossed wavy line group includes a first embossed wavy line and a second embossed wavy line in parallel, adjacent arc segments of the first embossed wavy line are connected by embossed lines of an annular structure, and the embossed wavy lines are inclined at 45°.

[0007] The utility model forms an interval depression structure through parallel embossed wavy lines and embossed wavy line groups, which can achieve multiple interruptions to block the penetration of dirt when wiping dirt, and at the same time play a drainage role to prevent the accumulation and penetration of dirt. The embossed wavy lines and the annular embossed lines are combined to form depressions of different sizes and depths, which can not only achieve deep and staggered dirt blocking and improve the cleaning effect, but also avoid sharp edges and corners to avoid scratching the skin.

[0008] Furthermore, in order to improve the dirt blocking and cleaning effects, the embossed lines of the annular structure include a first annular embossed line with a larger embossed area and a second annular embossed line with a smaller embossed area.

[0009] The embossed lines of the annular structure are cloud-shaped structures and / or "○"-shaped structures.

[0010] The first annular embossed lines are cloud-shaped structures, and the second annular embossed lines are "○"-shaped structures. The cloud-shaped structures and the "○"-shaped structures on the first embossed wavy lines are alternately arranged in sequence.

[0011] The width of the embossed wavy lines and lines is about 2 mm. Experiments have shown that an embossed line width of 1.5-2.5 mm not only ensures the softness and comfort of the non-woven fabric, but also has a good dirt-blocking effect.

[0012] The distance between the embossed wavy line groups is greater than the distance between the first embossed wavy line and the second embossed wavy line, and is preferably 1.5-2 times the distance.

[0013] The area of the cloud-shaped structure is larger than that of the "○"-shaped structure, forming a recessed structure of different sizes alternating in sequence, further enhancing the function of storing dirt and improving the cleaning effect.

[0014] A non-woven fabric comprises at least one non-woven fabric layer, on which the non-woven fabric embossed pattern structure is provided.

[0015] When the non-woven fabric comprises more than two layers, the direction of the embossed wavy lines on at least one layer of the non-woven fabric is perpendicular to the directions of the embossed wavy lines on other layers.

[0016] This nonwoven fabric is constructed by vertically bonding two layers of the aforementioned embossed nonwoven fabric structure, effectively increasing the nonwoven's tensile strength, making it thicker and more absorbent. It also provides double-sided dirt storage, enhancing its usability. When multiple layers are laminated, the embossed structure of the inner layer creates interlayer spaces, further enhancing the tissue's water absorption, drainage, and dirt storage capabilities.

[0017] The utility model has the characteristics of simple structure, strong practicability and good use effect, and is worthy of being widely promoted and used. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0022] See Figure 1 and 2 A flushable spunlace non-woven fabric, the top surface of which is embossed with a non-woven fabric embossed pattern structure, the non-woven fabric embossed pattern structure including a plurality of parallel embossed wavy line groups 6, each embossed wavy line group 6 including a first parallel embossed wavy line 61 and a second embossed wavy line 62, adjacent arc segments of the first embossed wavy line 61 are connected by embossed lines of an annular structure, and the annular embossed lines include a first annular embossed line 63 with a larger embossed area and a second annular embossed line 64 with a smaller embossed area.

[0023] In this embodiment, the first annular embossed lines 63 are cloud-shaped, and the second annular embossed lines 64 are circle-shaped. The first annular embossed lines 63 can also be circle-shaped, and the second annular embossed lines 64 can also be cloud-shaped, or other embossed shapes, such as concentric circular embossed patterns of different sizes. In this embodiment, both the first annular embossed lines 63 with a cloud-shaped structure and the second annular embossed lines 64 with a circle-shaped structure are used for illustration, and the first annular embossed lines 63 with a cloud-shaped structure and the second annular embossed lines 64 with a circle-shaped structure on the first embossed wavy line 61 are alternately arranged.

[0024] Under the action of the embossed wavy line group 6, the embossed wavy line group 6 is lower than the embossed wavy line group 6, forming an oblique strip-shaped depression. The first annular embossed line 63 with a cloud-shaped structure and the second annular embossed line 64 with an "○"-shaped structure make the oblique strip-shaped depressions spaced apart to form depressions of different sizes, so that when wiping dirt, each depression forms a different space to accommodate dirt. The multiple parallel groups of embossed wavy line groups 6 can intermittently block dirt for multiple times while playing a drainage role to prevent dirt from accumulating and penetrating, so as to improve the dirt blocking and cleaning effects. The combination of embossed wavy lines and annular embossed lines can not only achieve deep interlaced dirt blocking and improve the cleaning effect, but also avoid sharp edges and corners to avoid scratching the skin.

[0025] The embossed wavy lines are inclined at 45°, that is, the embossed wavy line groups 6 are inclined at 45° and are evenly distributed in parallel. The embossed wavy line groups 6 are symmetrical with the middle embossed wavy line group and have the same width.

[0026] The width of the embossed wavy lines and the circular embossed lines, i.e., the line width of each embossed pattern on the non-woven fabric, is 2 mm. Experiments have shown that a line width of 1.5-2.5 mm ensures both the non-woven fabric's softness and comfort while also effectively blocking dirt. The distance between the embossed wavy lines (6) is greater than the distance between the first embossed wavy line (61) and the second embossed wavy line (62), and preferably, the distance between the embossed wavy lines (6) is 1.5-2 times the distance between the first embossed wavy line (61) and the second embossed wavy line (62). Example

[0027] See Figure 1-3 A composite, flushable spunlace nonwoven fabric comprises a first nonwoven fabric layer 1, a connecting layer 3, and a second nonwoven fabric layer 2. The connecting layer 3 comprises spunlace nonwoven fiber threads, which are spunlace-threaded through the first nonwoven fabric layer 1 and the second nonwoven fabric layer 2, forming a hydroentangled composite connection between the first and second nonwoven fabric layers 1 and 2. Both the first and second nonwoven fabric layers 1 and 2 are provided with an embossed nonwoven pattern structure. The embossed wavy lines 6 between the first and second nonwoven fabric layers 1 and 2 are oriented perpendicularly to each other, significantly improving the structural toughness and tensile strength of the composite nonwoven fabric. Both sides of the composite nonwoven fabric can store dirt, are thick, and have high water absorption capacity, thereby improving the use effect.

[0028] This embodiment is composed of two layers of the flushable spunlace non-woven fabric of the first embodiment. For illustration, multiple layers can also be used. The embossed texture structure of the inner layer forms interlayer gaps, which can further improve the water absorption, drainage and dirt storage capabilities of the paper towel.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
