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, and is particularly applicable to flushable spunlace non-woven fabrics. Background Art

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

[0003] In the prior art, the patent document with the publication number of CN 202463014U discloses a surface embossed non-woven fabric, which is provided with concave and convex structures on the fabric surface, 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 flushability of the non-woven fabric are lost, and it is not suitable for human body wiping and flush degradation. Moreover, its press pattern is single, with many edges and corners, the wiping effect is poor, and it is easy to scratch the skin. Summary of the Utility Model

[0004] The utility model provides a non-woven fabric and its press pattern structure to solve the problems put forward 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 number of arc-shaped press embossing grooves arranged. Three concentric arc-shaped press embossing grooves are intermittently arranged to form a group of press embossing grooves. Each group of press embossing grooves is connected in cooperation with six groups of press embossing grooves arranged circumferentially around it. Taking any group of press embossing grooves as the center, among the six groups of press embossing grooves arranged circumferentially around it, in three groups of press embossing grooves arranged at intervals, the arc-shaped press embossing grooves close to the central press embossing groove group are located within the central press embossing groove group, and the two ends are respectively connected to the inner sides of two adjacent arc-shaped press embossing grooves of the central press embossing groove group. In the other three groups of press embossing grooves arranged at intervals, there are two arc-shaped press embossing grooves extending from the outside of the central press embossing groove group to the inside, and are respectively connected to the ends of the arc-shaped press embossing grooves of the central press embossing groove group and then extend to the inner side of the arc-shaped press embossing groove located within the central press embossing groove group and are connected to it. Each group of press embossing grooves is extended outward in the above-mentioned cooperative connection relationship with the six groups of press embossing grooves arranged circumferentially around it to form a press pattern structure.

[0007] In the above embossed pattern structure, each embossed groove line is arc-shaped, and both ends are connected to the inner sides of other arc-shaped embossed groove lines, without sharp corners, not easy to scratch the skin. Moreover, the three arc-shaped embossed groove lines within the same embossed groove line group cooperate to form a tee structure, which can play a role in drainage. At the same time, after embossing, the raised height at the corresponding part of the tee structure is relatively high, and the raised height at the intersection of the ends of the arc-shaped embossed groove lines is relatively low, forming a raised structure with different heights, increasing the specific surface area and friction of the non-woven fabric. And in cooperation with the embossed grooves, when wiping liquid dirt, its drainage effect enables the dirt to penetrate and drain horizontally to the grooves, reducing or avoiding the longitudinal penetration of the dirt through the non-woven fabric. At the same time, it promotes the storage of the dirt in the depressions with different heights, while ensuring the softness of the non-woven fabric, increasing the dirt cleaning strength, and improving the wiping effect.

[0008] In addition, the arc-shaped embossed groove lines are connected to each other to form a network structure with a triangular stable structure, improving the strength of the non-woven fabric, making it not easy to be damaged, and reducing or avoiding the risk of breakage due to the force of fingers during the wiping process.

[0009] The width of the embossed groove line is 1.5 - 2.5 mm. Through experiments, the embossed line width of 1.5 - 2.5 mm not only ensures the soft comfort of the non-woven fabric but also has a good effect of blocking dirt.

[0010] A non-woven fabric includes at least one non-woven fabric layer, and the above-mentioned non-woven fabric embossed pattern structure is provided on the non-woven fabric layer.

[0011] When the non-woven fabric adopts more than two non-woven fabric layers, the non-woven fabric layers are press-connected and compounded through the above-mentioned non-woven fabric embossed pattern structure or compounded through a spunlace non-woven fabric fiber silk connection layer.

[0012] Through compounding, the tensile strength of the non-woven fabric can be effectively improved, it is thick and has strong water absorption capacity. Also, interlayer voids can be formed in the non-woven fabric through the embossed pattern structure, further improving the water absorption, drainage, and dirt storage capabilities of the tissue paper.

[0013] 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

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0021] Refer to Figures 1-4 , a water-jet non-woven fabric that can be washed away, including at least one non-woven fabric layer, and a non-woven fabric embossed pattern structure is arranged on the non-woven fabric layer.

[0022] The non-woven fabric embossed pattern structure includes a plurality of arc-shaped embossed groove lines arranged. Refer to Figure 2 As shown, three concentric arc-shaped embossed groove lines 1-1, 1-2, and 1-3 are intermittently arranged to form a group of embossed groove lines 1,

[0023] Each group of embossed groove lines 1 is connected in cooperation with the six groups of embossed groove lines 1 arranged in its circumferential direction. Refer to Figure 1 And 3 , taking any group of embossed groove lines G as the center, among the six groups of embossed groove lines A, B, C, D, E, and F in its circumferential direction, among the three groups of embossed groove lines A, C, and E with intervals, the arc-shaped embossed groove lines A3, C1, and E2 close to the central embossed groove line group G are located in the central embossed groove line group G, and the two ends are respectively connected to the inner sides of the two adjacent arc-shaped embossed groove lines of the central embossed groove line group G. As Figure 3 Shown, the two ends of A3 are respectively connected to the inner sides of G1 and G2, the two ends of C1 are respectively connected to the inner sides of G2 and G3, and the two ends of E2 are respectively connected to the inner sides of G3 and G1, forming a tee structure in the central embossed groove line group G;

[0024] Among the other three sets of embossed groove line groups B, D, and F that are spaced apart, there are two arc-shaped embossed groove lines that extend from the outside to the inside of the central embossed groove line group G, and are respectively connected to the ends of the arc-shaped embossed groove lines of the central embossed groove line group G and then extend to the inside of the arc-shaped embossed groove lines located in the central embossed groove line group G and are connected to them. As Figure 3 shown, the two arc-shaped embossed groove lines B1 and B3 of the embossed groove line group B extend from the outside to the inside of the central embossed groove line group G. B1 and B3 are respectively connected to the two ends of G2 and then extend into the central embossed groove line group G, and are respectively connected to the inner arcs of the arc-shaped embossed groove lines A3 and C1 located in the central embossed groove line group G; the inner sides of the two arc-shaped embossed groove lines D1 and D2 of the embossed groove line group D are respectively connected to the two ends of G3, and the ends are connected to the inner arcs of E2 and C1 in the central embossed groove line group G; the inner sides of the two arc-shaped embossed groove lines F2 and F3 of the embossed groove line group F are respectively connected to the two ends of G1, and the ends located in the central embossed groove line group G are respectively connected to the inner arcs of A3 and E2;

[0025] Each embossed groove line group 1 expands outward with the above-mentioned mating connection relationship with the six groups of embossed groove lines in its circumferential direction to form an embossed pattern structure.

[0026] The width of the embossed groove line is 2 mm. Through experiments, an embossed line width of 1.5 - 2.5 mm can ensure both the soft comfort of the non-woven fabric and have a good effect of blocking dirt. Smaller or larger width dimensions of the embossed groove lines are not excluded and can also be used.

[0027] See Figure 1 and 4 , Figure 4It is a partial sectional structure schematic diagram of a single-sided embossed non-woven fabric. Each embossing groove line of the embossing pattern structure is arc-shaped, and both ends are connected to the inner sides of other arc-shaped embossing groove lines, without sharp corners, not easy to scratch the skin. And the three arc-shaped embossing groove lines inside the same embossing groove line group 1 cooperate to form a tee structure 2, which can play a role in drainage. And the convex height at the corresponding part of the tee structure 2 is relatively high, while the convex height at the end intersection 3 of the arc-shaped embossing groove line is relatively low, forming a convex structure with different heights, increasing the specific surface area and friction of the non-woven fabric. And in cooperation with the embossing groove, when wiping dirt, on the one hand, the tee drainage effect is used to make the fluid dirt penetrate and drain laterally to the groove, reducing or avoiding the longitudinal penetration of the dirt through the non-woven fabric. At the same time, it promotes the storage of solid dirt in the depressions with different heights. While ensuring the softness of the non-woven fabric, it increases the dirt cleaning strength and improves the wiping effect. Each arc-shaped embossing groove line is connected to each other to form a network structure with a triangular stable structure, improving the strength of the non-woven fabric, making it not easy to be damaged, and reducing or avoiding the risk of breakage due to finger force during the wiping process.

[0028] Further as a preferred solution, refer to Figure 5 , adopt a double-sided embossing process, and the non-woven fabric embossing pattern structure is embossed on both sides of the non-woven fabric, with double-sided symmetrical embossing, further improving the dirt storage capacity and wiping effect of the non-woven fabric. Embodiment

[0029] Refer to Figure 6 , a composite water-jet non-woven fabric that can be flushed, includes upper and lower non-woven fabric layers 4 and 5. The non-woven fabric embossing pattern structure described in the first embodiment is provided on both non-woven fabric layers, and is composite-connected through a water-jet non-woven fabric fiber silk connection layer 6. The water-jet non-woven fabric fiber silk penetrates through the non-woven fabric layers 4 and 5 to composite-connect the two. After composite connection, a gap 7 is formed between the two non-woven fabric layers, which plays a role in guiding flow, absorbing water, and storing dirt, improving the use effect.

[0030] The composite water-jet non-woven fabric that can be flushed can also be directly composite-connected by pressing through the above-mentioned non-woven fabric embossing pattern structure to form a structure such as Figure 4 or Figure 5 .

[0031] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
