Description

Technical Field

[0001] This application relates to the field of felt technology, and in particular to a down needle-punched nonwoven felt. Background Technology

[0002] Felt, with its strong elasticity, abrasion resistance, and good strength, has become a common fabric in people's lives. Different types of felt can be created by combining different materials to suit different applications. Fiber felt materials are entangled and glued together for easy cutting, and the felt has a relatively uniform surface distribution.

[0003] In the production process of down needle-punched nonwoven felt, adhesive is usually used to attach feathers or down between the fabrics. However, the adhesive method cannot guarantee the bonding strength between the materials, and delamination is likely to occur after long-term use. In addition, the down needle-punched nonwoven felt formed by adhesive bonding has reduced the softness of the finished product due to the introduction of adhesive, which reduces the comfort and usability. Utility Model Content

[0004] In order to improve the comfort of down needle-punched nonwoven felt during use, this application provides a down needle-punched nonwoven felt.

[0005] This application provides a down needle-punched nonwoven felt, which adopts the following technical solution:

[0006] A down needle-punched nonwoven felt includes a first connecting layer, a second interlayer, and a third connecting layer. The interlayer is disposed between the first connecting layer and the second connecting layer. The three layers—the first connecting layer, the interlayer, and the second connecting layer—are entangled and connected using a needle-punching process.

[0007] By adopting the above technical solution, the needle is used to repeatedly puncture the first connecting material layer, the sandwich material layer and the second connecting material layer, which facilitates the rapid bonding and fixing of the three layers of materials together. Nonwoven fabric products processed by needle punching have good bonding performance, strong fastness, full and firm hand feel, are easy to cut, have good uniformity, stable product structure and good heat insulation performance.

[0008] In one specific implementation, the first connecting layer can be made of nonwoven fabric, woven fabric or yarn material.

[0009] In one specific feasible implementation, the interlayer can be made of down, feathers, or wool.

[0010] By adopting the above technical solution, when needle punching is used to combine the first connecting layer and the second connecting layer, soft materials such as down, feathers or wool can form a pile surface on the felt, enhancing the comfort and experience during use, while also enhancing the warmth retention of the felt.

[0011] In one specific implementation, the second bonding layer can be made of nonwoven fabric, woven fabric or yarn.

[0012] In one specific implementation, a first protruding ridge is provided on the first connecting material layer, and the first protruding ridge is provided on the side close to the clamping material layer.

[0013] By adopting the above technical solution, a first protruding ridge is set on the first connecting material layer, so that when the needle pierces the first protruding ridge, it can hook out more fibers, increase the number of fiber entanglements, and enhance the strength of the felt.

[0014] In one specific implementation, the cross-section of the first protruding ridge is arc-shaped.

[0015] By adopting the above technical solution, the first protruding ridge is set to an arc shape. When the first connecting material layer and the second connecting material layer are joined together by needle punching, the arc-shaped first protruding ridge is easy to flatten to both sides, so that the processed felt is not prone to protrusion. While ensuring the connection strength, it does not affect the flatness of the felt.

[0016] In one specific implementation, a second protruding ridge is provided on the second connecting material layer, and the second protruding ridge is provided on the side close to the clamping material layer.

[0017] By adopting the above technical solution, a second protruding ridge is set on the second connecting material layer, so that when the needle pierces the second protruding ridge, it can hook out more fibers, increase the number of fiber entanglements, and enhance the strength of the felt.

[0018] In one specific implementation, the cross-section of the second protruding ridge is arc-shaped.

[0019] By adopting the above technical solution, the second protruding ridge is set to an arc shape. When the first connecting material layer and the second connecting material layer are joined together by needle punching, the arc-shaped second protruding ridge is easy to flatten to both sides, so that the processed felt is not prone to protrusion. While ensuring the connection strength, it does not affect the flatness of the felt.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The needle-punching method involves repeatedly piercing the first connecting layer, the sandwich layer, and the second connecting layer. This facilitates the rapid bonding and fixation of the three layers together. Nonwoven fabric products processed using this needle-punching method exhibit excellent bonding performance, strong fastness, a full and robust feel, and good breathability and water filtration.

[0022] 2. By setting the first and second convex ridges, when the needle pierces through the position of the second and first convex ridges, the first and second convex ridges increase the number of interlaced fibers, thereby enhancing the fiber entanglement strength, which is beneficial to improving the strength of the felt and preventing tearing.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a down needle-punched nonwoven felt, referring to... Figure 1 and Figure 2 The felt consists of a first connecting material layer 1, a second clamping material layer 2 on the first connecting material layer 1, and a third connecting material layer 3 on the side of the clamping material layer 2 away from the first connecting material layer 1. The first connecting material layer 1, the clamping material layer 2, and the second connecting material layer 3 together form a felt.

[0030] In this embodiment, the first connecting layer 1, the sandwich layer 2, and the second connecting layer 3 are joined together by needle punching to form a needle-punched nonwoven felt. The needles are used to repeatedly puncture the first connecting layer 1, the sandwich layer 2, and the second connecting layer 3, which facilitates the rapid bonding and fixing of the three layers together. The nonwoven fabric product processed by needle punching has good bonding performance, strong fastness, a full and solid feel, stable structure, and good heat insulation performance.

[0031] In this embodiment, the first connecting layer 1 is made of non-woven fabric, woven fabric or yarn material.

[0032] The interlayer 2 is made of down, feathers or wool.

[0033] The second connecting layer 3 is made of non-woven fabric, woven fabric or yarn material.

[0034] The interlayer 2 is sandwiched between the first connecting layer 1 and the second connecting layer 3, and is made of soft materials such as down, feathers or wool. When the first connecting layer 1 and the second connecting layer 3 are combined by needle punching, the soft materials such as down, feathers or wool can form a pile surface on the felt, which enhances the comfort and experience during use, and at the same time enhances the warmth retention of the felt.

[0035] In this embodiment, when needle-punching the first connecting layer 1, the clamping layer 2, and the second connecting layer 3, the first method is to insert the fibers of the first connecting layer 1 into the clamping layer 2, and insert the down and other fine hairs in the clamping layer 2 out of the first connecting layer 1; the second method is to insert the limiting element in the second connecting layer 3 into the clamping layer 2, and insert the down and other fine hairs in the clamping layer 2 out of the second connecting layer 3; the third method is to interweave the down in the clamping layer 2, and insert the fibers in both the first connecting layer 1 and the second connecting layer 3 into the clamping layer 2.

[0036] Reference Figure 3 and Figure 4 The first connecting material layer 1 is provided with a plurality of first protruding ribs 11. The first protruding ribs 11 are equidistantly arranged on the first connecting material layer 1. The first protruding ribs 11 are located on the side close to the clamping material layer 2. The cross-section of the first protruding ribs 11 is arc-shaped.

[0037] The second connecting material layer 3 is provided with a number of second protruding ribs 31. The second protruding ribs 31 are arranged at equal intervals on the second connecting material layer 3. The second protruding ribs 31 are located on the side close to the clamping layer 2. The cross-section of the second protruding ribs 31 is also arc-shaped. The second protruding ribs 31 are spaced apart from the first protruding ribs 11.

[0038] A first protruding ridge 11 is provided on the first connecting material layer 1, and a second protruding ridge 31 is provided on the second connecting material layer 3. The first connecting material layer 1 and the second connecting material layer 3 are combined by needle punching. When the needle pierces through the position of the second protruding ridge 31 and the first protruding ridge 11, the first protruding ridge 11 and the second protruding ridge 31 increase the number of interlaced fibers, thereby enhancing the fiber entanglement strength, which is beneficial to improving the strength of the felt and preventing tearing.

[0039] The implementation principle of this application embodiment is as follows: the first connecting material layer 1, the sandwich layer 2, and the second connecting material layer 3 are processed into needle-punched nonwoven felt by needle punching. The sandwich layer 2 is sandwiched between the first connecting material layer 1 and the second connecting material layer 3, and soft materials such as down, feathers, or wool are used to form a pile surface on the felt, making the felt more comfortable to use.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
