Description

Technical Field

[0001] This utility model relates to the field of textile materials technology, and more specifically, it relates to an elastic composite polyester fabric. Background Technology

[0002] Nylon is a man-made polymer material whose main material is polyamide fiber. Nylon fabric refers to fabric made of nylon as the main material. Nylon fabric has good abrasion resistance and is widely used in the production of bags, clothing and other products.

[0003] For example, the authorized announcement number CN219969083U discloses a high-elasticity composite nylon fabric, which includes a first protective layer, a nylon fabric, and a second protective layer. The first protective layer is fixedly connected to one end face of the nylon fabric, and the second protective layer is fixedly connected to the other end face of the nylon fabric. The first protective layer and the second protective layer have the same structure. By setting the first protective layer and the second protective layer on both sides of the nylon fabric respectively, the nylon fabric can be fully protected by the first protective layer and the second protective layer, so that the nylon fabric has strong tensile strength during use.

[0004] In the above, the arrangement of elastic cords and elastic strips is relatively simple. When the nylon fabric is subjected to tension in different directions, the tension will be concentrated in certain areas, causing the areas to tear due to external tension, which affects the service life of the nylon fabric. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an elastic composite polyester fabric with improved tensile strength.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An elastic composite polyester fabric includes a nylon layer and a protective layer, the protective layer comprising an outer layer, a middle layer, and an inner layer.

[0008] The inner layer is placed between the middle layer and the nylon layer, and the middle layer is placed between the outer layer and the inner layer.

[0009] Several upper elastic strips and several lower elastic strips are provided between the middle layer and the inner layer.

[0010] Both the upper and lower elastic strips are elastic.

[0011] The upper elastic strip is fixedly connected to the middle layer, and the lower elastic strip is fixedly connected to the inner layer.

[0012] The upper elastic strip is placed above the lower elastic strip, and the upper and lower elastic strips are staggered.

[0013] There are gaps between adjacent upper elastic strips and between adjacent lower elastic strips.

[0014] The gap is provided with a first connecting strip and a second connecting strip, both of which are elastic. Both the first connecting strip and the second connecting strip are fixedly connected to the inner wall of the gap, and the first connecting strip and the second connecting strip are fixedly connected in a cross manner.

[0015] An elastic post is provided at the intersection of the first connecting strip and the second connecting strip, and the elastic post is fixedly connected to the first connecting strip and the second connecting strip.

[0016] The present invention is further configured such that: a plurality of buffer columns are provided between the inner layer and the nylon layer, the buffer columns are fixedly connected to the inner layer and the nylon layer, the buffer columns are provided with through holes, and reinforcing columns are provided in the through holes. The reinforcing columns are semi-circular, the outer wall of the reinforcing columns is connected to the inner wall of the through holes, and there is a compression space between the reinforcing columns and the through holes.

[0017] The present invention is further configured such that: a plurality of elastic ropes are provided between the outer layer and the middle layer, the elastic ropes are elastic, both sides of the elastic ropes are connected to the inner wall of the outer layer and the inner wall of the middle layer, and a support bar is provided between adjacent elastic ropes, the support bar is elastic, and both ends of the support bar are connected to the elastic ropes.

[0018] The present invention is further configured such that: the outer layer is made of non-woven fabric, the middle layer is made of polyester fiber, and the inner layer is made of polymer film.

[0019] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0020] Elastic ropes are installed between the outer and middle layers, and upper and lower elastic strips are installed between the middle and inner layers. All three types of elasticity—elastic ropes, upper and lower elastic strips—increase the overall elasticity. The upper and lower elastic strips are staggered to disperse external tension. The combination of elastic ropes, support strips, upper and lower elastic strips, and the first and second connecting strips gives the nylon fabric strong tensile strength during use. Elastic posts are installed at the intersection of the first and second connecting strips, improving the structural strength between them. The buffer posts and reinforcing posts work together to absorb and disperse impact forces, further enhancing tensile strength. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] like Figures 1 to 2 As shown, the elastic composite polyester fabric includes a nylon layer 1 and a protective layer. The protective layer includes an outer layer 2, a middle layer 3, and an inner layer 4. The outer layer 2 is made of non-woven fabric, which can effectively block pollutants and bacteria in the external environment. The non-woven fabric has waterproof properties, so that external water stains can be blocked by the outer layer 2. The middle layer 3 is made of polyester fiber, which can enhance the overall structural strength. The inner layer 4 is made of polymer film, which has waterproof properties and can effectively prevent water from penetrating into the nylon layer 1.

[0027] Several horizontally distributed elastic cords 14 are installed between the outer layer 2 and the middle layer 3. Both sides of the elastic cords 14 are sewn to the outer layer 2 and the middle layer 3 with needle and thread. There are several support strips 15 between adjacent elastic cords 14. Both ends of the support strips 15 are sewn to the elastic cords 14. The support strips 15 and the elastic cords 14 are vertically distributed, and there is elasticity between the elastic cords 14 and the support strips 15, so that the elastic cords 14 and the support adhesive form a mesh structure with good elasticity.

[0028] The upper elastic strip 5 is sewn to the middle layer 3, and the lower elastic strip 6 is sewn to the inner layer 4. The upper elastic strip 5 is above the lower elastic strip 6, and the upper elastic strip 5 and the lower elastic strip 6 are distributed alternately.

[0029] There are gaps 7 between adjacent upper elastic strips 5 and between adjacent lower elastic strips 6.

[0030] The gap 7 contains a first connecting strip 8 and a second connecting strip 9. Both the first connecting strip 8 and the second connecting strip 9 are sewn to the gap 7 with needle and thread, and the first connecting strip 8 and the second connecting strip 9 are in a cross shape.

[0031] The first connecting strip 8 and the second connecting strip 9 are fixed together by sewing with needle and thread.

[0032] The upper elastic strip 5, lower elastic strip 6, first connecting strip 8, and second connecting strip 9 ensure more even force distribution and improve resilience and tensile strength. Even under high-intensity tension or torsion, the structure maintains its integrity and elasticity, and is less prone to deformation or breakage.

[0033] An elastic post 10 is located at the intersection of the first connecting strip 8 and the second connecting strip 9. The elastic post 10 is integrally formed with the first connecting strip 8 and the second connecting strip 9, and the elastic post 10 is made of rubber.

[0034] There are several buffer pillars 11 between the inner layer 4 and the nylon layer 1. The buffer pillars 11 are elastic and are all fixed to the inner layer 4 and the nylon layer 1 by needle and thread.

[0035] The buffer column 11 has a through hole 12, and a reinforcing column 13 is installed inside the through hole 12. The arc surface of the reinforcing column 13 is integrally formed with the inner wall of the through hole 12.

[0036] The buffer column 11 first absorbs the initial impact, and then compresses into the compression space between the reinforcing column 13 and the through hole 12, further dispersing and mitigating the impact force. This improves the impact resistance and extends the service life of the nylon fabric.

[0037] Operating principle: When the nylon layer 1 is subjected to tension, the outer layer 2 first contacts the external tension, and then the tension is applied through the elastic cord 14 and the support strip 15. The elastic cord 14 and the support strip 15 pull the external force, and as a result, the force is applied through the middle layer 3 to the upper elastic strip 5, the lower elastic strip 6, the first connecting strip 8 and the second connecting strip 9, where the force is evenly distributed. Then, the force is applied through the inner layer 4 to the buffer column 11. The buffer column 11 and the reinforcing column 13 disperse the external impact force, and finally, the force reaches the nylon layer 1. Through the combination of the elastic cord 14, the support strip 15, the upper elastic strip 5, the lower elastic strip 6, the first connecting strip 8 and the second connecting strip 9, the nylon fabric has strong tensile strength during use.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
