Description

Technical Field

[0001] This invention belongs to the field of nonwoven fabric structure technology, and particularly relates to a longitudinally stretched breathable nonwoven fabric. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, is composed of oriented or randomly arranged fibers. It is called cloth because it resembles fabric in appearance and possesses some of its properties. Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. Currently, non-woven fabrics are generally laminated with other functional fabrics to form composite non-woven fabric structures. However, these composite non-woven fabrics typically require regular washing of the surface. After washing, moisture seeps into the structure, resulting in a long drying time and making the structure inconvenient to use. Therefore, it is necessary to upgrade and modify the existing structure to improve its breathability and drying properties after washing. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides a longitudinally stretched breathable nonwoven fabric with a structure that can be stretched to improve its breathability and drying performance.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A longitudinally stretched breathable nonwoven fabric includes an upper connecting layer, a nonwoven core layer, a bottom support layer, a side enclosure layer, a telescopic airbag, and an airflow control component. The upper connecting layer is connected to the lower side of the nonwoven core layer. The lower side of the nonwoven core layer is connected to the bottom support layer. The upper connecting layer and the bottom support layer are connected around their perimeters by the side enclosure layer. Multiple longitudinal ventilation holes are evenly distributed on the nonwoven core layer, extending vertically through both the upper and lower ends of the nonwoven core layer. Multiple pre-embedded grooves are evenly distributed on the upper end of the nonwoven core layer. Each of the pre-embedded grooves contains a telescopic airbag; the upper end of each of the longitudinal ventilation holes is connected to a telescopic airbag; the airflow control component is installed on the bottom support layer; the airflow control component inflates or deflates the multiple telescopic airbags; when the upper connecting layer is pressed downwards, the multiple telescopic airbags deflate, causing them to be pre-embedded in the pre-embedded grooves; when the airflow control component inflates the multiple telescopic airbags, they extend upwards and press against the upper connecting layer, causing the upper connecting layer to rise upwards.

[0005] Furthermore, the airflow control assembly includes a ventilation duct, a piston cylinder, a piston rod, a one-way intake valve, an exhaust branch pipe, and an exhaust valve; a ventilation duct is installed inside the bottom support layer; the upper side of the ventilation duct is connected to multiple longitudinal ventilation holes; a piston cylinder is installed at the outer end of the ventilation duct; the piston rod is connected to the lower side of the piston cylinder; a one-way intake valve is installed at the outer end of the ventilation duct, and the one-way intake valve is located outside the piston cylinder; the exhaust branch pipe is installed at the outer end of the ventilation duct and located outside the piston cylinder, and an exhaust valve is installed on the exhaust branch pipe.

[0006] Furthermore, a receiving groove is formed at one end of the bottom support layer; a bottom opening is formed on the lower side of the receiving groove; the piston cylinder, piston rod, one-way intake valve, exhaust branch pipe, and exhaust valve are all installed in the receiving groove; the lower end of the piston rod extends to the bottom opening.

[0007] Furthermore, multiple insertion channels are evenly opened on the lower side of the upper connecting layer; multiple insertion posts are provided at the upper end of the non-woven fabric core layer; the insertion channels are slidably sleeved on the insertion posts.

[0008] Furthermore, the bottom support layer is made of polypropylene material.

[0009] Furthermore, the upper connecting layer is a reinforcing layer; the reinforcing layer is made of carbon fiber mesh.

[0010] Furthermore, the side enclosure layer is a folded non-woven fabric structure.

[0011] Furthermore, a wear-resistant layer is connected to the upper end of the upper connecting layer.

[0012] Furthermore, the wear-resistant layer is made of polyester fiber material.

[0013] The beneficial effects of this invention are as follows: 1. In normal use, to ensure structural stability, the upper connecting layer, non-woven fabric core layer, and bottom support layer are sequentially arranged from top to bottom, providing a stable experience for users. When improved ventilation and drying efficiency is required after cleaning, multiple telescopic airbags are inflated using an airflow control component. This causes the airbags to fill with airflow and extend upwards, pressing against the upper connecting layer and lifting it upwards. Simultaneously, the side enclosure layer is stretched, separating the upper connecting layer and the non-woven fabric core layer to facilitate rapid airflow and significantly improve drying efficiency. After drying, the upper connecting layer is pressed downwards, causing the multiple telescopic airbags to release air and embed themselves in pre-embedded grooves, thus restoring the structure and achieving stable use.

[0014] 2. This invention utilizes the reciprocating movement of the piston rod to allow airflow to continuously enter the ventilation pipe through the one-way intake valve. The airflow then enters multiple longitudinal ventilation holes through the ventilation pipe, thereby inflating the telescopic airbags. When degassing is required, the exhaust valve is opened, thus squeezing the upper connecting layer downwards, causing the multiple telescopic airbags to compress and degas. The airflow enters the ventilation pipe through the longitudinal ventilation holes and is then discharged through the exhaust branch pipe on the ventilation pipe, making it flexible and convenient to adjust and use.

The upper connecting layer 1 is connected to the lower side of the nonwoven core layer 2. The lower side of the nonwoven core layer 2 is connected to the bottom support layer 3. The upper connecting layer 1 and the bottom support layer 3 are connected around their perimeters by the side enclosure layer 4. A plurality of longitudinal ventilation holes 21 are evenly distributed on the nonwoven core layer 2. The longitudinal ventilation holes 21 extend vertically through the upper and lower ends of the nonwoven core layer 2. A plurality of pre-embedded grooves are evenly distributed on the upper end of the nonwoven core layer 2. 22; A telescopic airbag 5 is pre-embedded and installed in each of the pre-embedded grooves 22; the upper end of each of the longitudinal ventilation holes 21 is connected to a telescopic airbag 5; the airflow control component 6 is installed on the bottom support layer 3; the airflow control component 6 inflates or deflates the multiple telescopic airbags 5; when the upper connecting layer 1 is pressed downward, the multiple telescopic airbags 5 deflate, and the multiple telescopic airbags 5 are pre-embedded in the pre-embedded grooves 22; when the airflow control component 6 inflates the multiple telescopic airbags 5, the multiple telescopic airbags 5 extend upward and press against the upper connecting layer 1, causing the upper connecting layer 1 to be pushed upward.

[0022] like Figures 1 to 5 As shown, in order to inflate and deflate the telescopic airbag 5, the airflow control assembly 6 further includes a ventilation pipe 61, a piston cylinder 62, a piston rod 63, a one-way intake valve 64, an exhaust branch pipe 65, and an exhaust valve 66; a ventilation pipe 61 is installed inside the bottom support layer 3; the upper side of the ventilation pipe 61 is connected to multiple longitudinal ventilation holes 21; a piston cylinder 62 is installed at the outer end of the ventilation pipe 61; the piston rod 63 is connected to the lower side of the piston cylinder 62; a one-way intake valve 64 is installed at the outer end of the ventilation pipe 61, and the one-way intake valve 64 is located outside the piston cylinder 62; the exhaust branch pipe 65 is installed at the outer end of the ventilation pipe 61 and located outside the piston cylinder 62, and an exhaust valve 66 is installed on the exhaust branch pipe 65. Furthermore, a receiving groove 31 is provided at one end of the bottom support layer 3; a bottom opening 32 is provided on the lower side of the receiving groove 31; the piston cylinder 62, piston rod 63, one-way intake valve 64, exhaust branch pipe 65, and exhaust valve 66 are all installed in the receiving groove 31; the lower end of the piston rod 63 extends to the bottom opening 32.

[0023] like Figures 1 to 5 As shown, in order to improve the structural stability of the upper connecting layer 1 and the nonwoven core layer 2, multiple insertion channels 11 are evenly opened on the lower side of the upper connecting layer 1; multiple insertion posts 23 are provided at the upper end of the nonwoven core layer 2; the insertion channels 11 are slidably sleeved on the insertion posts 23.

[0024] like Figures 1 to 5As shown, the bottom support layer 3 is made of polypropylene. The upper connecting layer 1 is a reinforcing layer 7; the reinforcing layer is made of carbon fiber mesh. The side enclosure layer 4 is a folded non-woven fabric structure. A wear-resistant layer is connected to the upper end of the upper connecting layer 1. The wear-resistant layer is made of polyester fiber.

[0025] In normal use, to ensure structural stability, the upper connecting layer 1, non-woven fabric core layer 2, and bottom support layer 3 are sequentially arranged from top to bottom, providing a stable surface for use. When improved air permeability and drying efficiency are required after washing, the airflow control component 6 inflates multiple telescopic airbags 5, causing them to expand upwards and press against the upper connecting layer 1. Simultaneously, the side enclosure layer 4 is stretched, separating the upper connecting layer 1 and the non-woven fabric core layer 2 to facilitate rapid airflow and significantly improve drying efficiency. After drying, the upper connecting layer 1 is pressed downwards, causing the multiple telescopic airbags 5 to release air and embed themselves in the pre-embedded groove 22, thus restoring the structure and achieving stable use.

[0026] This invention utilizes the reciprocating movement of the piston rod 63 to allow airflow to continuously enter the ventilation pipe 61 through the one-way air intake valve 64. The airflow then enters multiple longitudinal ventilation holes 21 through the ventilation pipe 61, thereby inflating the telescopic airbags 5. When it is necessary to vent, the exhaust valve 66 is opened, thus squeezing the upper connecting layer 1 downward, causing the multiple telescopic airbags 5 to compress and vent. The airflow enters the ventilation pipe 61 through the longitudinal ventilation holes 21 and is then discharged through the exhaust branch pipe 65 on the ventilation pipe 61. This design allows for flexible and convenient adjustment and use.
