New non-woven building materials
Non-woven products production technology has broken through the traditional textile principles, without going through the traditional textile processing technology. The textile raw materials or filaments are oriented or randomly arranged to form a fiber network structure, and then reinforced by mechanical, thermal bonding or chemical methods, to obtain non-woven products, with a short production process, high degree of automation, high efficiency, production Low cost, rich processing raw materials and other advantages. The application of non-woven product production technology to building insulation materials can greatly reduce the production cost of thermal insulation materials, increase production efficiency, and be more energy-efficient and environmentally friendly, and provide more comprehensive utilization of resources. At the same time, it can also provide various functions of products.
At present, non-woven fabrics have been developed for nearly three decades, and their world production is progressing at an annual growth rate of 10% to 14%. China's non-woven industry is based on continuous innovation, and it has been adapted to a diversified market. Since 2010, it has maintained a rapid development. Nowadays, China has become the world's largest non-woven producer and consumer, with mature non-wovens. Production process, and sufficient or even excess nonwoven production capacity.
The biggest advantage of non-woven fabric production technology
is that in addition to processing traditional textile raw materials, it is also possible to comprehensively reuse recycled textile waste in order to reduce construction costs and to use functional fibers to impart more special properties to the material. The chemical fibers involved in the non-woven fabric include viscose fibers, polyester fibers, polypropylene fibers, polyamide fibers, polyvinyl alcohol fibers, etc., and most of them are recycled fibers, such as polyesters made from recycled bottle sheets. Fibers, in line with the current conservation-friendly green environmental protection concept for the comprehensive utilization of resources; the inorganic fibers involved include glass fibers, carbon fibers, metal fibers, ceramic fibers, etc., and can utilize the functionalities of inorganic fibers to develop nonwovens with various special properties. Products, which have become the mainstream research direction of the nonwovens industry today.
