Description

Graphene functionalized high-performance cashmere product and preparation method thereof
Technical Field
The invention relates to the technical field of graphene textile application, in particular to a graphene functionalized high-performance cashmere product and a preparation method thereof.
Background
The graphene is a super-light, ultra-thin, super-strong and super-large specific surface area quasi-two-dimensional nano carbon crystal material, and the surface density is about 0.77mg/m2The thickness of the single-layer graphene is about 0.34nm, the toughness of the graphene is excellent, the elastic modulus is 1.0TPa, the microscopic strength can reach 30GPa, the thickness is more than 100 times of that of the traditional steel, and the theoretical specific surface area is 2630m2A/g, and has very high electric and heat conducting properties, for example, the resistivity of graphene is 2 × 10-6Omega cm, electron mobility can reach 2 × 105cm2/V.S horizontal thermal conductivity at room temperature of about 5 × 103W/m.K. The single-layer graphene is flexible and flaky, has light transmittance of 97.7 percent, high thermal stability, high chemical stability, and excellent anti-permeability and anti-wear performance. In addition, the graphene also has a good photo-thermal conversion function and a far infrared physiotherapy effect, and the far infrared emission frequency of the graphene is mainly concentrated between 5.6 and 15 micrometers, which is just close to the human body infrared emission frequency range. In addition, graphene plays a good antibacterial role in the textile, and improves the antistatic property, the ultraviolet resistance, the flame retardant property and the wear resistance of the yarn and the fabric. Therefore, the fiber has wide application in various fields of mechanics, electronics, optics, thermology, new energy, biology, medical treatment, textile, seawater desalination and the like in recent years, and particularly has great application prospect in the fields of artificial fiber and textile.
The cashmere grows on the outer epidermal layer of the goat, covers the thin fine cashmere at the root of the goat coarse hair, grows in cold winter, resists wind cold, falls off after being heated in spring, naturally adapts to the climate, and belongs to rare special animal fibers. The cashmere has irregular thin and deep curls, consists of scale layers and cortex layers, has no pith layer, has the density of scales of about 60-70/mm, the cross section of fibers is approximately circular, the diameter of the fibers is thinner than that of fine wool, the average fineness is more than 14-16 mu m, the fineness irregularity is small and is about 20%, the length of the fibers is generally 35-45 mm, and the cashmere is light, thin, soft and smooth, has moderate fiber strength and high elasticity, and has a natural and soft color. Cashmere is so precious that it is not only due to its scarce yield (only 0.2% of the total world production of animal fibres), but also its excellent quality and characteristics. The cashmere fiber contains a lot of air, forms an air layer, can prevent the invasion of external cold air, keeps the body temperature not to be reduced, is thinner than wool, has thinner outer-layer scales, is smoother, lighter, softer and more flexible than the wool, is particularly suitable for manufacturing underwear, is light, soft, slippery and comfortable when being worn next to the skin, and is incomparable with any fiber, so the cashmere fiber is called as 'fiber gem', 'fiber queen', 'soft gold', and the like.
Cashmere products such as cashmere yarns, cashmere sweaters, cashmere underwear, cashmere overcoats, cashmere scarves and the like are processed by taking cashmere as a raw material, have the advantages of fine and soft hand feeling, smoothness, luster, good heat retention and comfortable wearing, but have poor antibacterial performance, antistatic performance, uvioresistant performance, wear resistance, flame resistance and the like, and the photothermal conversion efficiency of natural cashmere is not high.
In the textile field, the application of graphene in artificial synthetic fibers and fabrics is reported more, and through the functionalization of graphene, some performances of yarns and fabrics are improved to a certain extent. However, few reports on graphene-functionalized cashmere products have been reported so far.

Wherein the graphene sheet is a single-layer or few-layer graphene, and the particle size of the graphene sheet is less than 10 μm. The graphene functionalized high-performance cashmere product has good antistatic, uvioresistant and antibacterial properties, and also has a self-heating function under sunlight irradiation, and compared with a common cashmere product, the surface temperature of the product can be increased by 10-30 ℃ in sunlight.
The preparation method of the graphene functionalized high-performance cashmere product comprises the following steps of (1) adding 50g of graphene oxide powder into 10L pure water, carrying out ultrasonic treatment for 50min, then diluting with pure water to obtain a 0.25% uniformly dispersed graphene oxide aqueous solution, (2) adding 13g of hexadecyl dimethyl tertiary amine into 50kg of ethylene glycol, then soaking 10kg of previously washed cashmere product for 25min, taking out, washing with pure water, naturally airing or drying at 50 ℃ to obtain a cashmere product with a surface provided with positive charges, (3) putting the cashmere product obtained in the step (2) into 100L, soaking and reacting in the graphene oxide aqueous solution obtained in the step (1) for 40min, then taking out, soaking and washing for more than 3 times from the solution, reacting in pure water at 95 ℃ for 15min to obtain a graphene oxide modified cashmere product, (4) adding 45g of ascorbic acid into pure water of 100L pure water, completely dissolving, then taking out, soaking and washing the graphene oxide modified cashmere product obtained in the step (3) for more than 3 min, and drying at a temperature of 60 ℃ after the graphene oxide modified cashmere product is completely dissolved, and then taking out, and drying the cashmere product obtained by soaking and carrying out, and drying at a temperature of 20 ℃ or more than 60 ℃ to obtain a graphene oxide modified cashmere product.
Fig. 1 and 2 show SEM images of the surface morphology of the graphene functionalized high-performance cashmere product and SEM images of the surface morphology of the cashmere product before the graphene is functionalized. As can be seen from the figure, there is no impurity on the fiber surface of the untreated cashmere product, and the surface is a scaly corrugated surface. After functionalization with graphene, it is clear that graphene sheets 2 are relatively uniformly distributed on the surface of cashmere fiber 1, and the size of graphene sheets 2 is almost 10 μm or less.
Under the irradiation of natural light, the surface temperature of the pure cashmere can be increased to 45-55 ℃ from room temperature (22 ℃) after 5 minutes, and the surface temperature of the graphene composite cashmere can be increased to 64-80 ℃. Therefore, the graphene composite cashmere product has very high photo-thermal conversion efficiency, and the surface temperature can be increased by 10-30 ℃ compared with that of a pure cashmere product under the same condition.
