Description

Technical Field

[0001] This invention relates to the field of knitted fabric technology, specifically to an antibacterial cooling knitted fabric and its application. Background Technology

[0002] As living standards improve, consumers have increasingly diverse functional demands for knitted fabrics, with antibacterial and cooling properties becoming core requirements for summer clothing and home textiles.

[0003] Existing antibacterial cooling fabrics are mostly modified by single functional additives, which have problems such as poor functional stability, insufficient antibacterial durability, and short-lived cooling experience, making it difficult to meet the dual needs of long-lasting antibacterial effect and continuous cooling.

[0004] Graphene, as a novel two-dimensional material, has excellent thermal conductivity and antibacterial properties, but its surface inertness is strong and its compatibility with fiber substrates is poor. Direct addition can easily lead to agglomeration, which cannot fully realize its functional advantages. Calcium carbonate, as a common inorganic filler, can help improve the cooling sensation and mechanical properties of fabrics, but when added alone, its dispersion is poor, which can easily lead to a rough hand feel and rapid functional degradation of the fabric.

[0005] In existing technologies, how to achieve simultaneous improvement in fabric antibacterial properties, cooling sensation, and mechanical properties through precise modification and synergistic formulation of additives has become an urgent technical problem to be solved. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the purpose of this invention is to provide an antibacterial cooling knitted fabric and its application to solve the problems mentioned in the background art.

[0007] The present invention solves the technical problem by adopting the following technical solution:

[0008] This invention provides an antibacterial and cooling knitted fabric, the raw materials of which, by weight, include: 50-70 parts polyester fiber, 20-30 parts viscose fiber, 10-20 parts bamboo charcoal fiber, 2-5 parts modified graphene agent, 3-6 parts calcium carbonate incorporating agent, 0.5-1.5 parts dispersant, 0.3-0.8 parts antioxidant, and 1-2 parts softener; the modified graphene agent is prepared through the following steps:

[0009] S1: Add graphene to a sufficient amount of silane solution and sonicate it at 350-400W for 1 hour. After sonication, a silane-modified graphene solution is obtained. The silane solution is prepared by silane coupling agent KH560, 75-80% ethanol aqueous solution and sodium dodecylbenzenesulfonate in a weight ratio of 2:(5-8):(1-2).

[0010] S2: Add 10-15% of the total amount of additive to the silane-modified graphene liquid, mix and then ball mill. The ball milling speed is 1000-1500 r / min and the ball milling time is 2h. After ball milling, filter and dry to obtain the modified graphene agent. The additive includes, by weight, 2-5 parts of nano titanium dioxide, 1-3 parts of yttrium oxide, 5-8 parts of nano attapulgite, and 1-2 parts of illite.

[0011] Preferably, the dispersant is zinc stearate or polyethylene glycol, the antioxidant is antioxidant 1010, and the softener is an organosilicon softener.

[0012] Preferably, the calcium carbonate additive is prepared by the following steps:

[0013] S11: Mix 3-5 parts calcium carbonate, 5-8 parts lanthanum chloride solution (5% by mass) and 1-2 parts nanocellulose evenly to obtain calcium carbonate solution;

[0014] S12: Mix 1-2 parts of calcium sulfate whiskers, 2-3 parts of boron nitride and 3-5 parts of calcined talc with 5-8 parts of 5% sodium citrate solution to obtain the mixing solution;

[0015] S13: Mix the calcium carbonate solution and the conditioning solution at a weight ratio of (3-5):7, and stir at 550-750 r / min for 1 hour. After stirring, filter and dry to obtain the calcium carbonate conditioning agent.

[0016] Preferably, the graphene is single-layer or double-layer graphene with a particle size of 50-100 nm; the nano-titanium dioxide has a particle size of 20-50 nm, and the nano-attapulgite has a particle size of 30-80 nm.

[0017] Preferably, the polyester fiber is fine denier polyester with a fineness of 0.5-1.0 dtex; the bamboo charcoal fiber has a bamboo charcoal content of ≥30%.

[0018] This invention also provides a method for preparing an antibacterial cooling knitted fabric, comprising the following steps:

[0019] S100: Raw material pretreatment: Polyester fiber, viscose fiber and bamboo charcoal fiber are opened and combed to remove impurities and obtain pretreated fibers.

[0020] S200: Additive Dispersion: Add modified graphene agent, calcium carbonate modifier, dispersant, antioxidant, and softener to deionized water, stir evenly, and prepare a functional dispersion;

[0021] S300: Fiber modification: Immerse the pretreated fiber in a functional dispersion solution at a bath ratio of 1:20-1:30 and keep it at 60-70℃ for 2-3 hours. After taking it out, dehydrate it and dry it at 100-110℃ for 2-3 hours to obtain the modified fiber.

[0022] S400: Spinning: The modified fibers are blended and spun at a speed of 300-400 r / min to obtain knitted yarn;

[0023] S500: Knitting: Knitting yarn is woven on a circular knitting machine at a knitting density of 20-30 stitches / inch to obtain knitted fabric;

[0024] S600: Finishing: The knitted fabric is pre-shrinked, desized, dyed and set in sequence. The setting temperature is 130-150℃ and the setting time is 3-5 minutes to obtain antibacterial cool knitted fabric.

[0025] Preferably, in step S200, the solid content of the functional dispersion is 10-15%; in step S600, desizing is performed using amylase at a temperature of 50-60°C for 30-40 minutes.

[0026] The present invention also provides an application of an antibacterial cooling knitted fabric, which is used to prepare summer clothing, home textiles or medical protective equipment; the summer clothing includes T-shirts, shorts, and sun protection clothing; the home textiles include bed sheets, duvet covers, and cooling mats; and the medical protective equipment includes the inner layer of medical masks and the lining of protective clothing.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] This invention prepares modified graphene agents through a customized modification process. First, graphene is ultrasonically modified using a silane solution composed of silane coupling agent KH560, ethanol aqueous solution, and sodium dodecylbenzenesulfonate to improve its dispersibility and surface activity. Then, a specific ratio of nano-titanium dioxide, yttrium oxide, nano-attapulgite, and illite compound additives is added for ball milling and compounding. This not only further enhances the antibacterial properties of graphene but also synergistically improves its thermal conductivity and cooling effect, solving the problems of graphene agglomeration and insufficient functional performance.

[0029] The calcium carbonate additive of this invention is prepared by compounding calcium carbonate with lanthanum chloride and nanocellulose to form a calcium carbonate solution, and then mixing it with a solution of calcium sulfate whiskers, boron nitride, calcined talc and sodium citrate in a specific ratio. Lanthanum chloride and sodium citrate can improve the dispersion stability of calcium carbonate, while nanocellulose, calcium sulfate whiskers and boron nitride can synergistically enhance the mechanical properties and cooling durability of the fabric. Calcined talc can help improve the breathability and softness of the fabric. Together with the modified graphene agent, it forms a synergistic effect to achieve simultaneous optimization of antibacterial, cooling and mechanical properties.

[0030] This invention combines modified graphene agent with calcium carbonate additive, and blends it with polyester, viscose, and bamboo charcoal fiber. Through reasonable spinning, weaving, and finishing processes, the resulting knitted fabric has both long-lasting antibacterial and continuous cooling properties, as well as good softness, breathability, and mechanical strength. It has a wide range of applications and can be used in summer clothing, home textiles, and medical protective equipment.

[0031] This invention, through verification using multiple comparative examples, demonstrates that the combined use of modified graphene agent and calcium carbonate additive, the addition of additives and specific ratios in the modified graphene agent, and the addition of the conditioning liquid in the calcium carbonate additive play a key role in improving the antibacterial properties, cooling effect, and mechanical properties of the fabric, highlighting the inventiveness and practicality of this invention.

[0077] Performance testing

[0078] The knitted fabrics prepared in Examples 1-3 and Comparative Examples 1-5 were tested for antibacterial properties, cooling properties, and mechanical properties. The test standards and results are as follows:

[0079] 1. Antibacterial performance test

[0080] According to GB / T 20944.3-2008 standard, the antibacterial rate of the fabric against Escherichia coli and Staphylococcus aureus was tested. The test results are shown in Table 1 below:

[0081]

[0082] Cooling performance test

[0083] Referring to the GB / T 35263-2017 standard, the instantaneous cooling value (Q-max) and 2-hour cooling retention rate of the fabric were tested. The higher the Q-max value, the better the instantaneous cooling sensation, the higher the cooling retention rate, and the better the continuous cooling effect. The test results are shown in Table 2 below.

[0084]

[0085] Mechanical property testing

[0086] The tensile strength of the fabric was tested according to GB / T 3923.1-2013 standard; the color fastness to rubbing (dry rubbing and wet rubbing) of the fabric was tested according to GB / T 3920-2008 standard. The test results are shown in Table 3 below.

[0087]

[0088] The test results above show that:

[0089] 1. Antibacterial properties: The fabrics in Examples 1-3 all achieved an inhibition rate of over 98.7% against Escherichia coli and Staphylococcus aureus, which is significantly better than the respective comparison ratios.

[0090] Comparative Example 1, without the addition of modified graphene agent, showed a significant decrease in antibacterial rate, indicating that the modified graphene agent is the core component of the fabric's antibacterial performance. Comparative Example 2, without the addition of calcium carbonate additive, showed a lower antibacterial rate than the example, indicating that the calcium carbonate additive and the modified graphene agent have a synergistic antibacterial effect. Comparative Example 3, without the addition of additives, and Comparative Example 4, with a change in the additive ratio, both showed a decrease in antibacterial rate, indicating that specific ratios of additives in the modified graphene agent can significantly enhance the antibacterial effect. Comparative Example 5, without the addition of additive liquid, showed a decrease in antibacterial rate, indicating that the components in the additive liquid can help improve the antibacterial performance.

[0091] 2. Cooling performance: The instantaneous cooling value Q-max of Examples 1-3 all reached above 0.25, and the cooling retention rate after 2 hours reached above 86.7%, demonstrating excellent continuous cooling effect.

[0092] Comparative Example 1, without the addition of modified graphene agent, and Comparative Example 2, without the addition of calcium carbonate additive, both showed a significant decrease in cooling performance, indicating that the synergistic effect of the two can improve the cooling effect and its durability. Comparative Examples 3-5, due to changes in the preparation parameters of the additives, all showed lower cooling performance than the examples, proving that the preparation process and ratio of the modified graphene agent and calcium carbonate additive of the present invention are necessary.

[0093] 3. Mechanical properties: The fabrics in Examples 1-3 all have a breaking strength of 362N or higher and a color fastness to rubbing of grade 4 or higher, indicating good mechanical properties and color fastness.

[0094] The breaking strength of each comparative example was lower than that of the example, and the color fastness also decreased, indicating that the combined use of modified graphene agent and calcium carbonate modifier can not only improve the functional performance, but also optimize the mechanical properties and dyeing stability of the fabric.

[0095] In summary, the present invention, through the specific preparation of modified graphene agent and calcium carbonate additive, combined with a reasonable fiber ratio and preparation process, produces knitted fabrics that exhibit excellent antibacterial, cooling, and mechanical properties. Compared with the prior art, this invention represents a significant improvement and possesses outstanding creativity and practicality.
