Hakka traditional decorative patterns are the epitome of local life and production customs, politics and economy, culture and art and other history and culture. The themes of Hakka traditional decorative patterns come from the real world or the imaginary world, expressing the expectation and beautiful vision of life. At the same time, it is also the essence of artists accumulated through life in the past dynasties, which has a certain impact on the integration of modern art design and traditional culture. Photochromic materials have the characteristics of reversible color change under the action of light. They have relevant applications in many fields, such as architecture, currency anti-counterfeiting, clothing decoration and so on. Firstly, this paper briefly expounds the Hakka traditional culture. According to the introduction of Hakka traditional culture, this paper leads to the design of Hakka traditional decorative patterns based on Hakka traditional culture, and discusses the decorative technology, decorative parts, application scope and development history of Hakka traditional decorative patterns. Secondly, this paper briefly summarizes the photochromic materials, and leads to the category, principle and mechanism of organic photochromic materials. In this paper, electrospinning technology is introduced, and relevant experiments are designed. The results show that the composites with MAPE have better flexural, compressive and impact strength when the length of carbon nanofibers changes consistently. In the bending performance comparison experiment, the experimental data show that the lowest value of the group with MAPE is 15MPa higher than the highest value without MAPE. In the comparative test of compressive properties, the experimental data show that there is a difference of 30MPa between the composites with MAPE and those without MAPE. Moreover, when the length of carbon nanofibers is 40um, the overall performance of the composites is the best. This paper takes the design of Hakka traditional architectural decoration pattern with nano organic photochromic new materials as an experiment. Experiments show that nano organic photochromic new materials have better properties than traditional building materials in flexural modulus, compressive modulus and thermal stability.

“…The fiber membrane is treated with alcohol solution or alcohol vapor. The degree of expansion and shrinkage of the fiber membrane treated with alcohol is reduced, the strength characteristics, quality characteristics, covalent bond expansion, and shrinkage of the nanofiber membrane are improved, and the toughness of the sample is greatly improved, thereby achieving the purpose of cross-linking [6,7]. At the same time, it is necessary to pay attention to the different conditions of patients in the application of nanomaterials in lower limb joints, so it is necessary to conduct a careful examination of patients before using nanomaterials for rehabilitation treatment [8].…”

This study mainly explores the electrospinning of nanofiber-based materials and the application of the technology to lower extremity joint exercise rehabilitation. In response to people’s concerns, this study mainly discusses electrospinning technology from the aspects of the safety of nanomaterials prepared by electrospinning technology and the application of nanomaterials prepared by electrospinning technology in lower limb joints. In the safety study of nanomaterials, six groups of experiments were set up to measure the joints of nanomaterials prepared by electrospinning technology under pressures of 500 N, 510 N, 520 N, 530 N, 540 N, and 550 N. For compression resistance, when the pressure is 540 N, the compressive performance of the nanomaterial is preferably 96%. In terms of the application of nanomaterials, 100 patients with lower extremity sprains in the Affiliated Hospital of Sun Yat-sen University were divided into 5 groups and then divided into 6 groups. Patient recovery rate when the device is applied to the patient’s lower extremity joint. Patients had the best recovery rate of 92% when the immobilization device was used for 6 days. The use of arthrodesis did not affect the patient’s other factors. The experimental results show that when the pressure is 540 N and the fixation device is used for 6 days, the nanofiber material prepared by electrospinning technology has the best rehabilitation effect on lower limb joint movement.

The study examined separazione non-woven material obtained by the method of electrohidrodinamica hamowania from solutions of polysulfone in various solvents. The influence of the concentration and dynamic viscosity of spinning solutions on the electroforming process and the fiber diameter of non-woven materials is shown. The concentration dependences and ranges of changes in the dynamic viscosity that determine the nature of spinning and its transition from the process of electrospray liquid (ERW) to the actual process of electroforming fibers (EFV) are established. The possibility of predicting the fiber diameter and pore size of a nonwoven material is shown. It is established that the preferred solvents for the preparation of separation materials from polysulfone are dichloroethane, cyclohexanone and their mixtures.
