Technical Field

[0001] The invention relates to the technical field of textile materials, in particular to a Kusma cooling fiber and a preparation method thereof. Background Art

[0002] As people's requirements for quality of life increase, the functional demand for textiles is increasing. Traditional fibers often cause discomfort in high temperature environments, especially in hot seasons, and lack effective temperature regulation. Therefore, the development of fibers with excellent cooling properties has become a major challenge for the textile industry. Although some cooling fibers already exist in the prior art, they generally have problems such as poor air permeability, short duration of cooling effect, or high processing costs.

[0003] Secondly, the preparation process of traditional fibers often involves a lot of chemical treatment, which not only increases the environmental burden, but also has potential impacts on human health. Therefore, developing a fiber material that has excellent cooling properties, good environmental protection and health has important practical significance and application prospects. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a Kusma cooling fiber and a preparation method thereof, which solves the problems in the prior art of poor air permeability, unsustainable cooling effect and poor environmental protection of the cooling fiber.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A Kusma cooling fiber comprises the following components in parts by weight:

[0008] Base materials: 20-30 parts polyester, 10-20 parts nylon, 15-20 parts polyamide;

[0009] Cooling additives: 5-8 parts of nano-grade zinc oxide, 6-10 parts of graphene nanosheets, and 5-8 parts of ceramic powder.

[0010] Preferably, the Kusma cooling fiber comprises the following components in parts by weight:

[0011] Base material: 25 parts polyester, 15 parts nylon, 18 parts polyamide;

[0012] Cooling additives: 7 parts of nano-zinc oxide, 8 parts of graphene nanosheets, and 7 parts of ceramic powder.

[0013] The present invention further discloses a method for preparing Kusma cool fiber, comprising the following steps:

[0014] Step 1: Raw material pretreatment:

[0015] Precisely metering and fully mixing polyester, nylon, polyamide, nano-grade zinc oxide, graphene nanosheets, and ceramic powder according to weight ratio to obtain a mixture;

[0016] Step 2: Melt Spinning:

[0017] The mixture is melt-extruded and a double nozzle or multi-component spinning technology is used to spray a solution containing a base material on one side and a solution containing a micropore generating agent on the other side. The two phases are combined and formed during the spinning process to form a primary fiber with a microporous structure.

[0018] Step 3: Stretching and heat setting:

[0019] The primary fibers are stretched in multiple stages to optimize the physical properties of the fibers, and the fiber structure is fixed by heat setting to ensure the durability of the cooling effect.

[0020] Step 4: Initial surface treatment:

[0021] The fiber surface is treated with low-temperature plasma technology to improve the adhesion of the cool coating and give the fiber certain antibacterial and deodorizing properties;

[0022] Step 5: Surface reprocessing:

[0023] The fiber surface is treated with hydrophilicity to enhance the fiber's ability to absorb moisture and perspiration, thus improving the cooling effect;

[0024] Step 6: Winding and packaging:

[0025] Finally, the treated fibers are wound into a roll to complete the entire preparation process.

[0026] Preferably, in step 2, the melting temperature is 250-320° C., and the melting time is 1-2 hours.

[0027] Preferably, in step 2, the micropore generating agent is a phosphate compound, and the amount added is 1-2% of the total weight of the mixture. Phosphate compounds can promote the formation of micropores inside the fiber during the spinning process, thereby increasing the specific surface area of ​​the fiber, improving the air permeability and cooling effect of the fiber.

[0028] Preferably, the phosphate compound is any one or more mixtures of potassium dihydrogen phosphate, triethyl phosphate, and tributyl phosphate. These phosphate compounds can effectively promote the formation of micropores inside the fiber during the spinning process through their unique chemical properties, and the size and distribution of these micropores can be accurately controlled by adjusting the type and amount of the phosphate compound.

[0029] Preferably, in step 3, the specific conditions of the stretching and heat setting are:

[0030] In the stretching stage, the fiber is gradually stretched to 2-3 times its original length at a speed of 10-20 meters per minute;

[0031] During the heat setting stage, the fiber is kept at a temperature of 180-220°C for 5-10 minutes to ensure the stability of the fiber structure and the durability of the cooling effect.

[0032] Preferably, in step 4, the specific parameters of the low-temperature plasma technology treatment are: treatment time 10-20 minutes, plasma power 50-100W, treatment gas is a mixture of argon and oxygen, wherein oxygen accounts for 10-20%. This treatment method can effectively clean the fiber surface, remove impurities, and form a uniform and dense coating, thereby improving the adhesion of the cool coating and the antibacterial and deodorizing properties of the fiber.

[0033] Preferably, in step 5, the hydrophilic treatment adopts a nano titanium dioxide aqueous solution immersion method. Specifically, by immersing the fiber in a nano titanium dioxide aqueous solution, a hydrophilic nano coating is formed on the fiber surface, thereby enhancing the moisture absorption and perspiration capacity of the fiber and further improving the cooling effect. The amount of nano titanium dioxide added is generally 1-3% of the fiber weight, the immersion time is 30-60 minutes, and the immersion temperature is controlled between room temperature and 50°C.

[0034] Preferably, the amount of nano titanium dioxide added is generally 1-3% of the fiber weight, the soaking time is 30-60 minutes, and the soaking temperature is controlled between room temperature and 50°C.

[0035] (III) Beneficial effects

[0036] The present invention provides a Kusma cool fiber and a preparation method thereof, which has the following beneficial effects:

[0037] 1. The present invention successfully prepares Kusma cooling fiber with excellent cooling performance by optimizing the combination of basic materials, adding cooling additives such as nano-zinc oxide, graphene nanosheets, and ceramic powder, and combining a unique preparation process. The fiber not only has a significant cooling effect, but is also long-lasting and stable, and can effectively improve the comfort of the wearer, and is particularly suitable for textile applications in hot seasons.

[0038] 2. In the preparation process of the present invention, phosphate compounds are used as micropore generators, and a uniformly distributed micropore structure is formed inside the fiber through melt spinning technology, which significantly increases the specific surface area and air permeability of the fiber and further enhances the cooling effect. At the same time, the presence of the micropore structure also helps to quickly dissipate the heat inside the fiber and keep the low temperature state of the fiber surface.

[0039] 3. The present invention uses low-temperature plasma technology and hydrophilic treatment on the fiber surface, which not only improves the adhesion of the cool coating, but also gives the fiber certain antibacterial and deodorizing properties. Low-temperature plasma technology can clean the fiber surface, remove impurities, and form a uniform and dense coating; while hydrophilic treatment enhances the fiber's moisture absorption and perspiration capacity, allowing the fiber to remain dry while further improving the cool effect.

[0040] 4. The Kusma cooling fiber prepared by the present invention has good environmental protection and health. In the preparation process, a combination of physical and chemical methods is adopted to avoid the potential impact of a large number of chemical treatments on the environment and human health. At the same time, cooling additives such as nano-zinc oxide, graphene nanosheets, and ceramic powders are all environmentally friendly materials and will not cause harm to the human body and the environment.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] The embodiment of the present invention provides a Kusma cooling fiber, comprising the following components in parts by weight:

[0045] Base material: 20 parts polyester, 10 parts nylon, 15 parts polyamide;

[0046] Cooling additives: 5 parts of nano-zinc oxide, 6 parts of graphene nanosheets, and 5 parts of ceramic powder.

[0047] like Figure 1 As shown, the embodiment of the present invention also provides a method for preparing Kusma cooling fiber, comprising the following steps:

[0048] Step 1: Raw material pretreatment:

[0049] According to the preset ratio, polyester, nylon and polyamide are precisely measured to ensure the accurate proportion of each component. At the same time, nano-zinc oxide, graphene nanosheets and ceramic powders are pre-treated, such as drying and screening, to ensure their uniform dispersion and good performance.

[0050] Step 2: Melt Spinning:

[0051] The pre-treated base material and cooling additive are placed in a melting device and melt-mixed at a set melting temperature of 250°C and a time of 1 hour to ensure that the components are fully mixed. Subsequently, a double nozzle or multi-component spinning technology is used to spray a solution containing the base material on one side and a solution containing a micropore generator on the other side. The two phases are combined and formed during the spinning process to form a primary fiber with a microporous structure.

[0052] During the spinning process, the diameter, length and internal structure of the fiber can be controlled by adjusting the spinning parameters and nozzle design; secondly, during the spinning process, a micropore generating agent solution containing 1% by total weight of phosphate compounds is sprayed simultaneously. Specifically, the phosphate compound is potassium dihydrogen phosphate. During the spinning process, these phosphate compounds can effectively promote the formation of micropores inside the fiber through their unique chemical properties, and the size and distribution of these micropores can be precisely controlled by adjusting the type and addition amount of the phosphate compound, so that a uniformly distributed micropore structure is formed inside the fiber. The micropore structure helps to increase the specific surface area and air permeability of the fiber, thereby enhancing the cooling effect.

This treatment method can effectively clean the fiber surface, remove impurities, and form a uniform and dense coating, improving the adhesion of the cool coating and the antibacterial and deodorizing properties of the fiber.

[0060] Step 5: Surface reprocessing:

[0061] The fiber surface is treated with hydrophilicity to enhance the fiber's ability to absorb moisture and perspiration, and to improve the cooling effect. Specifically, the hydrophilic treatment adopts the method of soaking the fiber in a nano-titanium dioxide aqueous solution, that is, by soaking the fiber in a nano-titanium dioxide aqueous solution, a layer of hydrophilic nano-coating is formed on the fiber surface, thereby enhancing the fiber's ability to absorb moisture and perspiration, and further improving the cooling effect. The amount of nano-titanium dioxide added is generally 1% of the fiber weight, the soaking time is 30 minutes, and the soaking temperature is controlled between room temperature and 50°C.

[0062] Step 6: Winding and packaging:

[0063] The treated fibers are subjected to necessary post-treatment, such as washing and drying, to ensure the cleanliness and stability of the fibers. Finally, the fibers are wound into a tube to complete the entire preparation process.
