Description

Technical Field

[0001] This invention belongs to the field of fabric technology, and in particular relates to a light-heat-storing fabric and its manufacturing process. Background Technology

[0002] Clothing initially appeared for the purpose of covering the body, but over time it has evolved to become more functional (practical), such as providing warmth in cold environments.

[0003] Currently, fabrics on the market primarily improve the thermal insulation performance of clothing through the following methods.

[0004] 1. Increase the number or thickness of clothing fabrics to block the entry of cold air and isolate the body surface from the temperature difference with the outside world.

[0005] 2. Adding layers between garments is also a common design for warmth. These layers can be filled with insulating materials such as silk floss, down, or polyester fibers to improve the garment's warmth.

[0006] 3. Tight weaving reduces airflow within the garment, thus improving its warmth retention.

[0007] While all three types of fabrics offer some warmth, it is quite difficult to further improve their insulation performance. Summary of the Invention

[0008] This invention discloses a light-heat-storage fabric and its manufacturing process, which mainly solves the problem of limited heat insulation performance of traditional fabrics.

[0009] To achieve the aforementioned objective, the present invention provides a light-heat-storing fabric, comprising a surface layer, a bottom layer, and an intermediate layer. The surface layer is provided with a mesh structure, the bottom of the bottom layer is provided with a reflective layer, and the intermediate layer includes a support structure, the surface of which is provided with a light-heat-storing structure.

[0010] Preferably, the fabric is woven from a first yarn, a second yarn, and a third yarn, with the outer layer woven from the first yarn, the middle layer woven from the second yarn, and the bottom layer woven from the third yarn.

[0011] Preferably, the second yarn includes a fiber layer and a light-heat-storing layer covering its surface.

[0012] Preferably, the material of the photothermal storage layer is a light-absorbing and heat-storing masterbatch.

[0013] Preferably, the reflective layer is a fiber-modified layer, and the material of the fiber-modified layer is one of alumina and titanium dioxide.

[0014] Preferably, a manufacturing process for a light-heat-storing fabric is also provided, characterized by comprising the following steps:

[0015] Preferably, before adding the photothermal masterbatch to the spinning solution, it is first placed in a surfactant to pretreat the masterbatch by coating it with the surfactant. This improves its dispersibility and stability in the spinning solution.

[0016] Preferably, after adding the photothermal masterbatch to the spinning solution, the mixture is stirred at 60°C for 30 minutes. Then, the undispersed photothermal masterbatch agglomerates are removed using a filtration device to ensure the purity of the spinning solution.

[0017] S1:

[0018] Second yarn treatment:

[0019] Oil and dust on the fiber surface are removed by washing and ultrasonic cleaning.

[0020] Photothermal masterbatch, silane coupling agent and solvent are mixed under stirring, and then filtered, dried and ground in sequence to obtain photothermal masterbatch;

[0021] The photothermal masterbatch is mixed with the spinning solution and then spun to obtain the second yarn.

[0022] Third yarn treatment:

[0023] Alumina is dispersed in deionized water to form a uniform coating solution, and a nonionic surfactant is added to form the coating solution.

[0024] Oil and dust on the fiber surface are removed by washing and ultrasonic cleaning.

[0025] Immerse the third yarn in the coating solution, then remove it and remove any excess coating solution;

[0026] Place it in a drying room at 40-60℃ for 1-2 hours to complete the coating curing and form a fiber-modified layer;

[0027] S2: Use the first yarn to weave the surface layer and form a mesh on the surface, use the third yarn to weave the bottom layer, and use the second yarn to weave the middle layer and form holes in the middle layer.

[0028] The technical solution provided by this invention has at least the following technical effects:

[0029] Highly efficient light-heat storage performance: The light-heat storage structure in the fabric can effectively absorb and store light energy, converting it into heat energy to provide warmth. This is especially useful in cold environments, where it can be used as a passive insulation material.

[0030] Excellent breathability: The mesh structure on the surface layer increases the breathability of the fabric, preventing the wearer from feeling stuffy and promoting sweat wicking and dryness.

[0031] Energy-saving effect of the reflective layer: The bottom reflective layer can reflect some heat energy, reduce heat loss, and thus improve the heat insulation performance of the fabric.

[0032] Multi-layered structural design: The fabric consists of a top layer, a middle layer, and a bottom layer, each with its specific function. This multi-layered design makes the fabric more comprehensive and balanced in terms of performance. Attached Figure Description
