Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a nonwoven fabric with an edge-reinforced structure. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber (PET) and produced through a needle-punching process. It can be made in different thicknesses, feels, and hardnesses. Non-woven fabric has the characteristics of being moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic and odorless, inexpensive, and recyclable. It can be used in various industries, such as sound insulation, heat insulation, heating elements, masks, clothing, medical, and filling materials.

[0003] However, in actual operation, the inventors found that the following problems still exist: Non-woven fabric usually needs to be cut during preparation. The cut edges of the non-woven fabric are rough. When subjected to external force, the tear resistance of the cut edge is low and it is easy to tear, which affects the subsequent processing and performance of the non-woven fabric. In addition, the existing connection methods between non-woven fabric layers also have some shortcomings, such as weak connection, which makes it easy for the layers to separate during use.

[0004] Based on this, the present invention provides a nonwoven fabric with an edge-reinforced structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a nonwoven fabric with an edge-reinforced structure. Through structural innovation and material optimization, it significantly improves edge reliability and usability while ensuring the performance of the nonwoven fabric itself, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a non-woven fabric with an edge reinforcement structure, comprising a non-woven fabric and a U-shaped edge reinforcement strip, wherein the edge of the non-woven fabric is fitted with the U-shaped edge reinforcement strip, one end of the U-shaped edge reinforcement strip is fixedly installed with a metal buckle one, and the other end of the U-shaped edge reinforcement strip is fixedly installed with a metal buckle two, the metal buckle one and the metal buckle two are in a snap-fit ​​relationship, the U-shaped edge reinforcement strip includes a rubber wear-resistant layer, a polyester fiber braided tape and a reinforcing soft iron wire, the polyester fiber braided tape is located in the inner layer, the rubber wear-resistant layer is located in the outer layer, and the reinforcing soft iron wire is provided on the opposite side of the rubber wear-resistant layer and the polyester fiber braided tape.

[0007] Preferably, the nonwoven fabric includes hot-air nonwoven fabric, meltblown nonwoven fabric and spunbond nonwoven fabric, wherein the hot-air nonwoven fabric is located in the inner layer, the meltblown nonwoven fabric is located in the outer layer of the hot-air nonwoven fabric, and the spunbond nonwoven fabric is located in the outer layer of the meltblown nonwoven fabric.

[0008] Preferably, the thickness of the polyester fiber braided tape is 0.3-0.5 mm, and the thickness of the rubber wear-resistant layer is 0.2-0.3 mm.

[0009] Preferably, the rubber wear-resistant layer and the polyester fiber braided belt are connected by adhesive.

[0010] Preferably, the nonwoven fabric has connecting holes formed by punching, and metal buckles one and two are fitted inside the connecting holes.

[0011] Preferably, the layers of the hot air nonwoven fabric, meltblown nonwoven fabric and spunbond nonwoven fabric are bonded together by a hot press roller at 120-150℃, with the bonding points having a diameter of 2-3mm and a spacing of 10-15mm.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This nonwoven fabric with edge reinforcement features reinforced soft iron wires inside U-shaped edge reinforcement strips, enhancing edge rigidity and tensile strength to prevent edge deformation or tearing. The outer rubber abrasion-resistant layer provides wear resistance, while the inner polyester fiber woven tape offers structural support. These two layers are bonded together with adhesive to form a composite reinforcement layer, effectively improving edge tear resistance. The layers of hot-air nonwoven fabric, meltblown nonwoven fabric, and spunbond nonwoven fabric are connected by a 120mm joint. -150℃ hot roller bonding ensures tight bonding between layers, effectively preventing interlayer separation and improving the overall structural stability of the nonwoven fabric compared to existing technologies. The U-shaped edge reinforcing strip features two metal clips at both ends, forming a snap-fit ​​relationship. The nonwoven fabric has perforated holes for connection with the metal clips, facilitating quick and easy integration of the edge with the U-shaped edge reinforcing strip according to actual size requirements. Installation and disassembly are convenient. The rubber wear-resistant layer effectively reduces edge wear during use, extending service life. While enhancing edge and interlayer connections, it does not compromise the nonwoven fabric's inherent moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic, and odorless properties, ensuring its performance in various industries such as sound insulation, heat insulation, medical applications, and clothing.
