Description

Technical Field

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

[0002] Non-woven fabric, also known as non-woven fabric, is a fabric that does not require spinning and weaving. It is made by directional or random arrangement of textile fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabric has the characteristics of water resistance, breathability, non-toxic and tasteless, low price, and recyclability. In recent years, its scope of use has been continuously expanded and is widely used in many fields such as medical products and clothing.

[0003] A highly elastic nonwoven fabric is disclosed in a Chinese utility model patent with publication number CN201921128766.2, which includes an upper nonwoven fabric layer, a lower nonwoven fabric layer, and an elastic layer and an antibacterial layer disposed between the upper nonwoven fabric layer and the upper nonwoven fabric layer. The elastic layer is bonded to the lower surface of the upper nonwoven fabric layer, the antibacterial layer is bonded to the lower surface of the elastic layer, and the lower surface of the antibacterial layer is bonded to the lower nonwoven fabric layer. The antibacterial layer includes an intermediate layer, and hollow elastic protrusions are disposed on the upper and lower surfaces of the intermediate layer, and a number of antibacterial particles are disposed in the hollow elastic protrusions, so that the antibacterial layer has good antibacterial properties; the elastic layer provided makes the nonwoven fabric have good elasticity.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the current non-woven fabrics are mostly used to make products such as masks that are in close contact with the user's skin. The non-woven fabrics in the above-mentioned devices use a large amount of polyester. After the non-woven fabrics have been worn for a period of time, they are prone to pilling due to frequent friction, resulting in a poor user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a high-elastic breathable non-woven fabric.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a highly elastic breathable non-woven fabric, including an inner layer, an intermediate layer is arranged on the side wall of the inner layer, an outer layer is arranged on the side wall of the intermediate layer away from the inner layer, the inner layer includes a first breathable film layer and a wear-resistant layer arranged on the side wall of the first breathable film layer, and the intermediate layer is woven from blended fibers.

[0007] By adopting the above technical solution, when the staff uses non-woven fabric, the wear-resistant layer made of chemical fiber has good wear resistance and structural strength, thereby reducing the probability of non-woven fabric balloons and extending the service life of the non-woven fabric, thereby improving the staff's usage experience.

[0008] Furthermore, the blended fibers include flax fibers and polypropylene fibers twisted together.

[0009] By adopting the above technical solution, flax is one of the earliest natural fibers used by humans, with a history of more than 10,000 years. Flax fiber is a rare natural fiber, accounting for only 1.5% of the total natural fiber. Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. Its trade name in my country is polypropylene. Polypropylene fine denier long fiber has good luster, soft feel, good drape and low density. The intertwined flax fiber and polypropylene fiber have good structural strength and touch, thereby improving the structural strength of the middle layer.

[0010] Furthermore, the blended fibers also include silver ion fibers, which are twisted with flax fibers and polypropylene fibers, with the flax fibers accounting for 17-27%, the polypropylene fibers accounting for 73-83%, and the silver ion fibers accounting for 5-10%.

[0011] By adopting the above technical solution, the silver ion fiber has good antibacterial properties, thereby reducing the probability of mold on the non-woven fabric and improving the user experience of the staff.

[0012] Furthermore, the outer layer includes an elastic fiber layer arranged on the side wall of the middle layer away from the first breathable film layer, a second breathable film layer arranged on the side wall of the elastic fiber layer, and a waterproof layer arranged on the side wall of the second breathable film layer.

[0013] By adopting the above technical solution, the elastic fiber layer has good elasticity, the second breathable film layer has good air permeability, and the waterproof layer has good waterproofness, thereby improving the texture of the non-woven fabric and further improving the use experience of the staff.

[0014] Furthermore, adhesive layers are provided on two opposite side walls of the intermediate layer.

[0015] Furthermore, the waterproof layer is made of TPU.

[0016] By adopting the above technical solution, thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, referred to as TPU, is a (AB)n type block linear polymer. TPU has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance, and waterproofness. The waterproof layer made of TPU has good waterproofness.

[0017] Furthermore, a plurality of air holes distributed at equal intervals are provided on the side wall of the wear-resistant layer.

[0018] Furthermore, the wear-resistant layer is made of chemical fiber.

[0019] By adopting the above technical solution, chemical fiber is pressurized by chemical liquid, so that it is ejected from a small hole, thereby forming uninterrupted, continuous columnar or thin linear fibers. Chemical fiber has good wear resistance and structural strength, thereby increasing the service life of the wear-resistant layer and further improving the use experience of the staff.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff uses non-woven fabrics, the wear-resistant layer made of chemical fibers has good wear resistance and structural strength, thereby reducing the probability of non-woven fabric balloons and extending the service life of non-woven fabrics, thereby improving the staff's experience;

The inner layer 1 comprises a first breathable film layer 11 and a wear-resistant layer 12, and the wear-resistant layer 12 is arranged on the side wall of the first breathable film layer 11.

[0031] The middle layer 2 is woven from blended fibers 3, which include flax fibers 31, polypropylene fibers 32, and silver ion fibers 33. Flax is one of the earliest natural fibers used by humans, with a history of more than 10,000 years. Flax fiber 31 is a rare natural fiber, accounting for only 1.5% of the total natural fiber. Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by polymerization of propylene. Its trade name in my country is polypropylene. Polypropylene fine denier long fibers have good luster, soft hand feel, good drape, and low density. Silver ion fibers 33 have good antibacterial properties. The flax fibers 31, silver ion fibers 33, and polypropylene fibers 32 twisted together have good structural strength and touch, and reduce the probability of mold on the non-woven fabric, thereby improving the structural strength of the middle layer 2.

[0032] The outer layer 4 is arranged on the side wall of the middle layer 2 away from the inner layer 1, and the outer layer 4 includes an elastic fiber layer 41, a second breathable film layer 42 and a waterproof layer 43. The elastic fiber layer 41 is arranged on the side wall of the middle layer 2 away from the first breathable film layer 11, the second breathable film layer 42 is arranged on the side wall of the elastic fiber layer 41, and the waterproof layer 43 is arranged on the side wall of the second breathable film layer 42.
