[0017] In this embodiment, Figure 1 As shown, the graphene thermal fleece 6 is made by blending biomass graphene powder and polyester flakes.

[0018] Embodiment 2: A method for preparing a waterproof and warm ski protective clothing fabric, comprising the following specific steps: Step 1: Graphene fiber preparation, which is used to make natural or synthetic graphene into a spinning melt or solution, which is filtered and metered, extruded from a spinneret into a liquid stream, and then solidified into a fiber; The specific steps are as follows: S1, mixing process, mixing epoxy resin and carbon fiber evenly; S2, pretreatment, adding silicone rubber, oxidized modified graphene and additives to the mixture in the previous step, continuing to mix, and heating to 255-320°C; S3, extrusion molding: During extrusion molding, an injection molding machine equipped with an extruder head is used, and the extrusion temperature is 275-300°C; S4: obtaining a graphene fiber body; Step 2: warping, the graphene fiber obtained in the previous step is plied with the polyester fiber to obtain warp yarn and weft yarn, and the warp yarn and weft yarn are parallelly wound on the warp beam or weaving beam according to the specified length and width; Step 3: Preparation of composite waterproof layer 3: Evenly mix paraffin, polyvinyl alcohol, ethanol and film-forming agent to obtain a waterproof spray mixture; The mixing mass ratio of paraffin wax, polyvinyl alcohol, ethanol and film-forming agent is 1:0.3-0.6:2-5:1.5-2.5; Step 4: Textile preparation, using a loom for weaving production, preparing the fabric base 1, weaving using a doubled silk thread (such as Figure 3 As shown), a single warp yarn and two weft yarns are arranged alternately, and the warp yarn and the weft yarn are covered with a waterproof spray during the weaving process to obtain a fabric base layer 1; Step 5: preparing the cotton fiber 4, using a loom to weave the cotton fiber cloth, and in the weaving process, the elastic mesh is woven to be mixed with the cotton fiber 4, and the obtained cotton fiber 4 is covered on the inner surface of the fabric base 1, and the two are bonded and fixed by an ultrasonic suturing process; Step 6: Preparation of graphene thermal fleece 6: prepare several portions of biomass graphene powder, and in the process of blending polyester floccules, make the warp and weft yarn surfaces evenly covered with graphene powder. The warp and weft yarns in the polyester floccules weaving process are both single-strand yarns, and the obtained graphene thermal fleece 6 is attached to the inner surface of the cotton fiber 4; Step 7: Dry the fabric at high temperature to set it; The drying and shaping temperature is specifically divided into three stages: (1) In the first stage, the temperature is 40-50°C and the heating time is 15-20 minutes; (2) The second stage, the temperature is 70-75°C, and the heating time is 5-8 minutes; (3) In the third stage, the temperature is controlled within the range of 35-45°C after natural cooling to 40°C and heated for 15-25 minutes; Step 8: After the fabric is cooled to room temperature, the fabric for ski suit is obtained.

[0019] The fabric obtained according to the above preparation process can be used for the production of outdoor sportswear such as ski suits, down jackets, mountaineering suits, etc. Here, the production of ski protective clothing is taken as an example; The fabrics are cut accordingly according to production requirements, and ultrasonic sewing technology is used to connect and sew the fabric pieces. Ultrasonic sewing technology is a new type of wireless sewing technology that uses ultrasonic technology to combine two pieces of fabric together. There are no pinholes or stitches at the joints, which greatly reduces the possibility of water seepage in the clothing from the source, and implants intelligent factors to enhance the sports protection function of the ski suit while improving the convenience of putting on and taking off, sports flexibility, and sports warning.

[0020] In terms of appearance design, the ski suit version is innovatively designed, using bionic design inspired by nature to enhance the protection and flexibility of the ski suit. The bionic structure simulates the structure of animals in nature, such as hard plate structure and layered structure; it not only enhances protection but also maintains the flexibility and flexibility of the ski suit. In terms of collision protection, a cushioning layer is added to the ski suit to protect the human body; protective materials with better protection are used at the shoulder joints, elbow joints and spine, but because using thick protective materials at the ribs and clavicle will affect the comfort of exercise, lighter, thinner and softer foaming protective materials can be used at these two places; in material analysis, it was found that Poron polyurethane foam can provide up to 7 times more impact protection than other materials. It can not only absorb huge impact forces, but also has excellent resistance to compression deformation. The comparison of cushioning materials is summarized as follows Figure 2 As shown; through the summary of the three cushioning materials, Poron foam has a better protective effect, is not easily affected by low temperature environment, and can be cut into required shapes according to the design. Poron foam is selected as the cushioning layer of this design; Because the most common injury during skiing is falls caused by personal factors, the first parts of the lower body to touch the ground are usually the buttocks and knees. The most vulnerable parts are the coccyx, the upper end of the femur and the knees, followed by the hips and outer thighs. According to the bionic forms and structures of lobsters, turtles, honeycombs, etc., try to combine cushioning materials and ski suit fabrics for bionic design. Because the movement and bending of the knees and elbows are similar to that of a lobster's tail, such bionic production can give the knee and elbow joints a larger range of motion, wrap the knee and elbow joints intact, and provide better protection.

[0021] In terms of heat preservation and warmth retention, the innovative high-tech fabric is breathable and comfortable, and its waterproof performance is also guaranteed. The ski suit made of this fabric is very suitable for wearing on the snow; Since ski suits are easily damp when skiing, biomass graphene powder is blended with polyester flakes to produce biomass graphene inner warm fleece thermal insulation material, which is used in ski suits and has the characteristics of lightness, fineness, softness, good thermal insulation and good antibacterial properties. In terms of safety protection function, after the ski suit is illuminated by light, the reflective strips on the suit are very obvious and have a good reflective effect, which can ensure that the skiers behind can clearly see the warning in front when skiing at night; and the Recco search and rescue system is added; the Recco system is an electronic search and rescue system specially used for avalanche victims; it consists of a small reflector and a lightweight portable detector, which is used by rescue personnel. The detector can also identify signals reflected from other electronic devices, such as mobile phones, cameras, and radios, etc., to facilitate search and rescue by rescue personnel; the intelligent design ensures the safety of the wearer.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
