[0001] The utility model relates to the technical field of composite fabrics, and more specifically, to a floating long-line fabric with a composite TPU film. <0OO0003>Background Art

[0002] A composite fabric is a new type of material formed by bonding and laminating one or more layers of textile materials, non-woven materials and other functional materials. It is suitable for making textiles such as sofas and clothing, and is one of the indispensable fabrics for people's home life.

[0003] In order to improve the windproof and warm-keeping performance of winter fabrics, a film is further laminated on the basis of stacking multiple layers of fabrics. Although the warm-keeping effect is achieved, the overall fabric will be heavier, and it will be uncomfortable to wear when made into clothes. Moreover, it is not easy to bend after stacking multiple layers of fabrics, and gaps will be generated between the fabric and the body surface as the joints move, affecting the warm-keeping effect. Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a floating long-line fabric with a composite TPU film.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: The floating long-line fabric with a composite TPU film includes a base layer, and a number of concave grooves are hot-pressed on one side of the base layer. A number of fluff are fixed by flocking in the concave grooves. A TPU film is laminated on the side of the base layer with fluff. A soft layer is fixedly connected to the other side of the base layer, and a number of floating long-lines are provided on the soft layer.

[0006] The utility model is further set as follows: The length of the fluff is equal to the depth of the concave groove. The concave grooves are in a "field" shape on the base layer, and the width between adjacent concave grooves is less than the width of the concave groove.

[0007] The utility model is further set as follows: The base layer is woven from polyester yarns.

[0008] The utility model is further set as follows: The soft layer includes a number of fixed segments. The floating long-lines are arranged between adjacent fixed segments. The length of the floating long-lines is greater than the length between adjacent fixed segments. A warm-keeping deformation cavity is formed between the floating long-lines and the base layer. <000002OO>The utility model is further set as follows: The soft layer is formed by the warp and weft in a plain weave pattern. The weft is set as a composite yarn, and the warp is set as a polyester yarn.

[0010] The present invention is further configured such that: the composite yarn includes a yarn core and a first strand and a second strand spirally wound on its outer side, wherein the first strand is a graphene yarn and the second strand is a cotton yarn.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This composite TPU membrane's floating long-line fabric achieves multiple levels of warmth and comfort through its unique design. The base layer is woven from polyester yarn, and the TPU membrane effectively slows down airflow, enhancing warmth. Meanwhile, the special layout of the recessed grooves ensures the stability of the pile and the fabric's lightweight feel. The addition of a soft layer, particularly the weft design using a composite of graphene and cotton yarns, not only enhances the fabric's elasticity and comfort but also further slows down airflow through the floating long-line structure, improving warmth. The rapid warming properties of the graphene yarn and the softness and breathability of the cotton yarn combine to create a superior effect. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] The floating long thread fabric of this composite TPU film, such as Figure 1 As shown, it includes a base layer 1, which is woven from polyester yarn. The polyester yarn is woven in a plain weave pattern to form the base layer 1. Several recessed grooves are hot-pressed into one side of the base layer 1, and several piles 2 are flocked and fixed in the recessed grooves. A TPU film 3 is laminated to the side of the base layer 1 with the piles 2. The recessed grooves increase the cavity on the surface of the base layer 1, and the polyester yarn woven into the base layer 1 melts during hot pressing. After hot pressing and shaping, the polyester yarn solidifies to maintain the stability of the shape of the recessed grooves. The melting of the polyester yarn also affects the stability of the woven layer. The pores formed during the process are sealed, and the TPU film 3 is compositely fixed on one side of the groove opening on the base layer 1, so that a relatively closed space is formed in the groove, keeping the air in the groove relatively still and improving the lightness of the fabric. The pile 2 in the groove can further slow down the air circulation speed in the groove. Air has a low thermal conductivity and is a poor conductor of heat, thus improving the warmth retention of the fabric. The TPU film 3 has good elasticity and flexibility, as well as good weather resistance, improving the comfort and service life of the fabric.

[0018] As shown Figures 1-2 in the figure, the length of the fluff 2 is equal to the depth of the concave groove, ensuring that the fluff 2 can be filled in the concave groove. The fluff 2 stably serves the purpose of slowing down the air flow speed. Moreover, the length of the fluff 2 will not protrude from the concave groove, avoiding the situation that when the TPU film 3 is laminated, the long fluff 2 is pressed, which affects the lamination completion degree and firmness. The concave grooves are in a "field" shape on the base layer 1, and the width between adjacent concave grooves is smaller than the width of the concave groove. The concave grooves are evenly distributed, so the fluff 2 filled in the concave grooves is also evenly distributed on the base layer 1. Similarly, the relatively small width between adjacent concave grooves enables the concave grooves to have a larger distribution range on the base layer 1, improving the overall warmth retention effect of the base layer 1.

[0019] As shown<C Figures 1-2 in the figure, a soft layer 4 is fixedly connected to the other side of the base layer 1. The soft layer 4 is provided with a plurality of floating lines 5. The soft layer 4 includes a plurality of fixed segments 6. The floating lines 5 are arranged between adjacent fixed segments 6. The length of the floating lines 5 is greater than the length between adjacent fixed segments 6. A warmth retention deformation cavity is formed between the floating lines 5 and the base layer 1. The soft layer 4 is arranged on the side close to the body surface. The fixed segments 6 are arranged at both ends of the floating lines 5. The fixed segments 6 are adhesively bonded and fixed to the base layer 1. When the floating lines 5 are woven, no warp threads are provided. Thus, the weft part of the woven soft layer 4 will form a plurality of floating lines 5. The floating line part is softer in texture and more comfortable when contacting the body surface. Moreover, the loose floating lines 5 can also slow down the air flow speed, making the air between the body surface and the fabric as relatively static as possible, thereby reducing heat loss and achieving a warmth retention effect.

[0020] As shown Figures 1-2 in the figure, the soft layer 4 is formed by warp threads and weft threads in a plain weave pattern. The weft threads are set as composite yarns, and the warp threads are set as polyester yarns. The composite yarn includes a yarn core and the first strand and the second strand helically wound around its outer side. The first strand is set as a graphene yarn, and the second strand is set as a cotton yarn. The first strand and the second strand are wound around the yarn core through the process of mule spinning. The yarn core is selected as a spandex yarn. The first strand and the second strand are twisted with a low twist degree, making the first strand and the second strand more fluffy on the yarn core. The fluffy yarn will also increase the comfort when contacting the body surface.

[0021] As shown Figure 1As shown, the elastane yarn has good elasticity, thereby enhancing the elasticity of the whole soft layer 4, and in the process of joint movement, the soft layer 4 can be better pulled to deform, the relative displacement and gap between the soft layer 4 and the body surface are reduced, the soft layer 4 can be better wrapped outside the body surface, the warmth of the fabric is strengthened, the graphene yarn has high heat transfer efficiency and fast heating speed, the cotton fiber has soft texture, good moisture absorption and air permeability, and the comfort of the soft layer 4 when contacting the fabric is ensured.

[0022] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
