Three Trends in the Development of Medical and Health Textile Technology

On July 19th, in terms of technological development trends, medical and sanitary textiles present three trends: a variety of process technologies are further compounded, interdisciplinary fields are further integrated, and upstream and downstream technologies in the industrial chain tend to be integrated and innovative.　　 Surgical implantable textiles and in vitro filtration textiles are mostly dependent on imports. The focus of product development is on the development of special biomedical fibers, forming technology and product development, forming major achievements with independent intellectual property rights. Medical protective, health care, sanitary textiles and surgical non-implantable textiles are available in a large quantity and wide range. They have basically achieved domestic production and can be exported in large quantities. The focus of product development is on the development of specialized functional and differentiated products. Improve the level of product performance indicators.　　In the future, the research and development of medical protective textiles will pay more attention to the materials' anti-leakage technology, odor absorption technology, antibacterial, anti-blood penetration, antistatic, comfort and other functions. In terms of biomedical materials, in the future, we will continue to strengthen basic technology research, combined with in-depth research on the natural composition, structure and function of different races, human bodies, tissues, and organs, and conduct macro and micro bionic design and manufacturing. Research on alternatives. Biomaterials for tissue engineering are product technologies closely related to the textile industry in the biomedical field, including biomedical raw materials in the form of fibers and scaffold materials made with textile technology, which will be greatly developed in the future. Artificial kidney, artificial liver and artificial lung, substitute materials for soft tissue and interstitial tissue, and biomedical materials such as heart valves are the key research products.　　 In terms of high-end medical protective textiles, comprehensive development and improvement of the uniformity and product stability of medical protective materials, and continuous cost reduction, will be the development trend of such materials. SMS nonwoven composite materials will become the focus of development. The spunbond layer ensures high wear resistance, and the intermediate meltblown layer improves the product’s filtration efficiency, barrier performance, particle penetration resistance, hydrostatic pressure resistance, shielding performance and uniform appearance Performance, so as to achieve good filterability, liquid resistance and opacity.　　 In terms of new medical dressings, material efficiency, product high performance, and high nursing efficiency represent the general development direction of new medical dressings. Future products will pay more attention to biological activity and intelligence. The types of new medical dressings that can be developed include silver-containing antibacterial dressings, bioactive dressings and other products that require strong plasticity, good adhesion, good air and moisture permeability, antibacterial and healing properties, and have hemostatic and analgesic functions. In addition, it also has the effect of promoting the division of epithelial cells, fibroblasts and endothelial cells and the growth of extracellular matrix. It can effectively absorb wound exudate. After drying, it can form a physical barrier to prevent the invasion of foreign bacteria, which is epithelial growth. Create a good environment. Downstream application products include wound dressings, hemostatic sponges, medical absorbent cotton, medical absorbent gauze, gauze bandages, elastic bandages, plaster bandages, wound dressings, etc. In terms of new sanitary materials, more functional fiber materials such as biodegradable, antibacterial, and super absorbent will be used to improve the technology of disposable baby and elderly diapers, sanitary napkins, functional wet wipes and industrial wipes. Performance. Among the disposable sanitary materials, focus on the development of surface layer materials and diversion layer materials, research and develop the degradable properties of the materials, improve the softness and functionality of the surface layer materials, as well as the bulkiness and compositeness of the diversion layer, and enhance the Continuous differential diversion performance.
