Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to a high-strength outdoor sports composite fabric. Background Technology

[0002] Outdoor sports include activities such as camping, picnicking, mountaineering, rock climbing, rafting, adventure, and skiing. In addition to requiring physical fitness, outdoor sports also require participants to wear good outdoor clothing to adapt to harsh weather and complex geographical environments. Outdoor clothing is not fundamentally different from home clothing, but due to the characteristics of outdoor activities and sports, the requirements for clothing in terms of warmth, breathability, windproofness, and waterproofness are relatively strict and demanding. Existing outdoor sportswear, in order to facilitate more convenient activities for the wearer, has less protective structure for the wearer. When the wearer falls while wearing it for outdoor sports, the sportswear cannot cushion the impact on the wearer's body.

[0003] Furthermore, during outdoor activities, it is easy to be exposed to ultraviolet radiation. Excessive ultraviolet radiation may lead to skin cancer. While a UV-protective layer on fabric can provide good protection against ultraviolet radiation, in order for the fabric to have good UV protection, the fabric needs to have a relatively high density and a tight weave design to prevent ultraviolet rays from passing through. This results in poor breathability of the fabric, which cannot meet the breathability and heat dissipation needs of wearers during long-term outdoor activities. Utility Model Content

[0004] To overcome the shortcomings of existing technologies in providing insufficient protection and poor breathability for users during outdoor sports, this invention provides a high-strength outdoor sports composite fabric that not only provides protection for the wearer without affecting the fabric's flexibility and cushions the wearer's body parts in case of a fall, but also meets the wearer's breathability and heat dissipation needs during prolonged outdoor activities.

[0005] The present invention adopts the following technical solution.

[0006] A high-strength outdoor sports composite fabric includes a base fabric layer. A cushioning layer and a waterproof and breathable membrane are sequentially disposed on one side of the base fabric layer. The cushioning layer includes a first non-woven fabric and a second non-woven fabric. The first non-woven fabric has multiple radially extending and non-connected first breathable grooves. The second non-woven fabric has multiple weft-extending and non-connected second breathable grooves. A breathable space is formed between the first non-woven fabric and the second non-woven fabric. The projections of the first breathable grooves and the second breathable grooves on the vertical plane do not overlap.

[0007] A honeycomb airbag block is provided between the two adjacent second ventilation slots.

[0008] Preferably, the upper and lower surfaces of the honeycomb airbag block are both horizontal contact surfaces, the first non-woven fabric and the second non-woven fabric are fixedly connected to the contact surfaces at the upper and lower ends of the honeycomb airbag block, the cross-section of the honeycomb airbag block is hexagonal, and the interior of the honeycomb airbag block is filled with polyester fiber clusters.

[0009] Preferably, the thickness of the first nonwoven fabric and the second nonwoven fabric is 1-3 mm, and the thickness of the honeycomb airbag block is 3-5 mm.

[0010] Preferably, the waterproof and breathable membrane is made of PU material, and the thickness of the waterproof and breathable membrane is 3-5μm.

[0011] Preferably, the base fabric layer is woven from high-strength yarn, which includes an aramid core and elastic spandex spirally wound around the outside of the aramid core.

[0012] The beneficial effects of this utility model are as follows:

[0013] The first and second non-woven fabrics of this invention jointly create a breathable space, significantly improving the fabric's breathability. Because the projections of the first and second breathable channels on the vertical plane do not overlap, sunlight cannot directly pass through the first and second non-woven fabrics, resulting in excellent breathability. A honeycomb airbag block is placed between two adjacent second breathable channels. This honeycomb airbag block provides protection for the wearer without affecting the fabric's flexibility, offering cushioning in case of a fall. Furthermore, the honeycomb airbag block provides good support for the breathable space, preventing it from collapsing completely under pressure, effectively ensuring the fabric's breathability.

[0020] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0021] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] As attached Figure 1-3 The high-strength outdoor sports composite fabric shown includes a base fabric layer 1. A cushioning layer 2 and a waterproof and breathable membrane 3 are sequentially disposed on one side of the base fabric layer 1. The cushioning layer 2 includes a first non-woven fabric 21 and a second non-woven fabric 22. The first non-woven fabric 21 has multiple radially extending and non-connected first breathable grooves 211. The second non-woven fabric 22 has multiple weft-extending and non-connected second breathable grooves 221. A breathable space is formed between the first non-woven fabric 21 and the second non-woven fabric 22. The projections of the first breathable grooves 211 and the second breathable grooves 221 on the vertical plane do not overlap. A honeycomb airbag block 23 is disposed between two adjacent second breathable grooves 221.

[0023] The first nonwoven fabric 21 and the second nonwoven fabric 22 together create a breathable space, significantly improving the fabric's breathability. Thanks to the non-overlapping projections of the first breathable groove 211 and the second breathable groove 221 on the vertical plane, sunlight cannot directly pass through them, giving the fabric excellent UV protection. A honeycomb airbag block 23 is positioned between two adjacent second breathable grooves 221. This provides protection for the wearer without affecting the fabric's flexibility, offering cushioning in case of falls. Furthermore, the honeycomb airbag block 23 provides excellent support for the breathable space, preventing it from collapsing under pressure, effectively ensuring the fabric's breathability and meeting the protective needs of prolonged outdoor activities.

[0024] The design of the first ventilation groove 211 and the second ventilation groove 221 can effectively increase the breathable area of ​​the fabric, promote air circulation, and allow body heat to be quickly discharged, keeping the body dry and comfortable.

[0025] The waterproof and breathable membrane 3 can effectively prevent external moisture from entering without significantly affecting the breathability of the fabric.

[0026] In some embodiments, the upper and lower end faces of the honeycomb airbag block 23 are both horizontal contact surfaces 231, and the first non-woven fabric 21 and the second non-woven fabric 22 are fixedly connected to the contact surfaces 231 at the upper and lower ends of the honeycomb airbag block 23, respectively. The two highly flexible first non-woven fabrics 21 and 22 are firmly bonded to the contact surfaces 231 of the upper and lower end faces of the honeycomb airbag block 23 using a high-strength adhesive or hot melt adhesive. This connection method not only ensures the strength of the connection but also effectively disperses local stress, improving the stability of the overall structure. The first non-woven fabric 21 and 22 not only protect the honeycomb airbag block 23 but also enhance the windproof and waterproof effect of the fabric. The cross-section of the honeycomb airbag block 23 is hexagonal, and the interior of the honeycomb airbag block 23 is filled with polyester fiber clusters 232. This structure gives it both high strength and excellent cushioning performance. When compressed, the polyester fiber clusters 232 are compressed, like countless miniature springs, evenly dispersing the impact force and improving the pressure-bearing limit of the honeycomb airbag block 23. The hexagonal structure increases the spacing between adjacent honeycomb airbag blocks 23, thus preventing the honeycomb airbag blocks 23 from being too dense and reducing the flexibility of the fabric.

[0027] In some embodiments, the thickness of the first nonwoven fabric 21 and the second nonwoven fabric 22 is 1-3 mm, and the thickness of the honeycomb airbag block 23 is 3-5 mm. The honeycomb airbag block 23 with a thickness of 3-5 mm can maintain good flexibility while ensuring cushioning performance, and will not make the fabric too thick and difficult to bend.

[0028] In some embodiments, the waterproof and breathable membrane 3 is made of PU material, and its thickness is 3-5 μm. The PU molecular chain structure contains alternating soft and hard segments. The soft segments of the PU molecular chain have a certain degree of hydrophilicity, while the hard segments are generally composed of isocyanate groups, giving the membrane hydrophobic properties and preventing water droplets from passing through. The combined effect of the soft and hard segments gives the PU membrane its waterproof and breathable function.

[0029] In some embodiments, the base fabric layer 1 is woven from high-strength yarn 11, which includes an aramid core 111 and elastic spandex 112 spirally wound around the outside of the aramid core 111. Although the aramid core 111 has high strength, it is sensitive to ultraviolet light and has obvious light-induced discoloration problems. Moreover, prolonged exposure to ultraviolet light will cause a loss of strength. The elastic spandex 112 effectively protects the aramid core 111, preventing it from coming into contact with ultraviolet light during outdoor activities and avoiding the loss of strength of the aramid core 111.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
