Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a non-woven fabric with ductility. Background Art

[0002] Non-woven fabric is also called non-woven fabric. It is a kind of fabric that does not need to be spun and woven. It is formed by directional or random arrangement of textile short fibers or filaments to form a fiber web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It is a new type of fiber product with soft, breathable and flat structure formed by short fibers or filaments through various fiber web forming methods and consolidation technologies. The non-woven fabrics in the prior art generally do not have ductility. After being made into clothes, they cannot be extended with human activities, resulting in poor comfort. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a non-woven fabric with ductility in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a non-woven fabric with ductility, the non-woven fabric is wavy in the first extension direction, and the main trough portion and the main peak portion thereon are alternately distributed, and a plurality of secondary peak portions are arranged on the main trough portion, and the extension direction of the secondary peak portion is perpendicular to the extension direction of the main trough portion and the protrusion directions of the two are opposite, the top of the secondary peak portion is lower than the top of the main peak portion, and a plurality of secondary trough portions are arranged on the main peak portion, and the extension direction of the secondary trough portion is perpendicular to the extension direction of the main peak portion and the protrusion directions of the two are opposite, the bottom of the secondary trough portion is higher than the bottom of the main trough portion, and the secondary trough portions and the secondary peak portions are alternately distributed in the second extension direction, and the second extension direction is perpendicular to the first extension direction.

[0005] To further optimize the technical solution, the bottom of the secondary wave trough portion is lower than the top of the secondary wave peak portion.

[0006] To further optimize the technical solution, the distance between two adjacent secondary troughs in the second extension direction is smaller than the width of the secondary peak, and the distance between two adjacent secondary troughs in the first extension direction is smaller than the length of the secondary peak.

[0007] Compared with the prior art, the utility model has the following advantages: 1. The main troughs and main peaks on the non-woven fabric are alternately distributed, and a plurality of secondary peaks are arranged on the main troughs, and a plurality of secondary troughs are arranged on the main peaks, so that the non-woven fabric has a certain extensibility in the first direction; 2. The bottom of the secondary trough is lower than the top of the secondary peak, and the distance between two adjacent secondary troughs in the second extension direction is less than the width of the secondary peak, so that the non-woven fabric has a certain extensibility in the second direction.

[0010] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0011] Specific implementation method: Combination Figure 1 As shown, a non-woven fabric with ductility is wavy in a first extension direction, and the first extension direction can generally be the length direction or width direction of the non-woven fabric. The main wave valley 1 and the main wave peak 2 thereon are alternately distributed, and a plurality of secondary wave peaks 4 are arranged on the main wave valley 1. The openings of the secondary wave peaks 4 pass through the bottom of the main wave valley 1. The extension direction of the secondary wave peaks 4 is perpendicular to the extension direction of the main wave valley 1, and the convex directions of the two are opposite. The top of the secondary wave peak 4 is lower than the top of the main wave peak 2, so that the portion between the top of the main wave peak 2 and the top of the secondary wave peak 4 can be stretched when subjected to tension. The main wave crest portion 2 extends in one direction, and a plurality of sub-wave trough portions 3 are arranged on the main wave crest portion 2. The openings of the sub-wave trough portions 3 pass through the top of the main wave crest portion 2. The extending direction of the sub-wave trough portions 3 is perpendicular to the extending direction of the main wave crest portion 2 and the convex directions of the two are opposite. The bottom of the sub-wave trough portions 3 is higher than the bottom of the main wave trough portion 1, so that the portion between the bottom of the main wave trough portion 1 and the bottom of the sub-wave trough portions 3 can extend in the first direction when subjected to tension. The sub-wave trough portions 3 and the sub-wave crest portions 4 are alternately distributed in a second extending direction, and the second extending direction is perpendicular to the first extending direction, so that the non-woven fabric is easier to bend and softer in the second direction.

[0012] Furthermore, the bottom of the secondary trough 3 is lower than the top of the secondary crest 4. Since both the secondary trough 3 and the secondary crest 4 can be extended in the second extension direction, when the two overlap to a certain extent in the thickness direction of the non-woven fabric, and the distance between two adjacent secondary troughs 3 in the second extension direction is less than the width of the secondary crest 4, and the distance between two adjacent secondary troughs 3 in the first extension direction is less than the length of the secondary crest 4, the non-woven fabric can be extended in the second extension direction. The extensibility in the first extension direction and the second extension direction can be synthesized with the extensibility in other directions in the plane where the non-woven fabric is located, so that the non-woven fabric is also extensible in the direction inclined to the first extension direction or the second extension direction (and in the plane where the first extension direction and the second extension direction are located).

[0013] It should be understood that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present application should be included in the protection scope of the present application.
