| Sumario: | With the growth of the population and the improvement of people's quality of life, the consumption of textiles is increasing, but the number of textiles recycled and reused is relatively small. Especially in recent years, there have been more and more text iles containing conductive fibres, and their recycling methods are quite different from ordinary fibres. Therefore, reasonable recycling is required to avoid waste of resources. In this paper, a conductive nonwoven fabric is constructed by stainless steel fibres, and its feasibility is analyzed to further explore the feasibility of using recycled stainless steel fibres. The specific research contents are as follows: (1) Desk work Summarize the current types of conductive fibres, preparation methods, and app lications. The most suitable conductive fibres(stainless steel fibre) are selected by analyzing and comparing the electrical properties of these conductive fibres, the degree of impurities in their preparation, and the cost. The nonwoven fabric preparatio n method used in this experiment was analyzed, and the feasibility of using stainless steel fibres to construct conductive nonwoven fabrics was further determined by considering the matching degree of the process flow with the stainless steel fibres. Summa rize the methods for recycling and reusing conductive fibres, and summarize the types of products containing conductive fibres, especially stainless steel fibres, as potential waste sources. And put forward a plan for recycling and reusing these products w hen discarded. Summarize the current application of conductive cement and the types of conductive fibres suitable for it. Consider the possibility of conductive nonwovens as reinforcing materials to impart conductive properties to cement. (2) Experiment pa rt By comparing the conductive properties of nonwoven fabrics with different stainless steel fibre content and different fibre bonding methods, it can be seen that the higher the content of stainless steel fibres, the better the conductive properties of t he nonwoven fabric. However, the uniformity of the distribution of stainless steel fibres will affect the conductivity of the non the nonf non-- woven fabric, and woven fabric prepared by the cross structure has the best conductivity. However, the conductivity o woven fabrics will decrease with time, so heat treatment is required to improve the conductivity further |
