Surface chemical composition analysis and properties of flame-retardant lyocell fiber

摘要

With the progress of society and technology, textile materials have been continuously developed and innovated, which also makes it extend from the traditional textile field to industry, environmental protection, transportation, military, aerospace, medicine, plastics, biotechnology and many other fields. However, according to statistics, since the majority of textile materials are flammable, more than 50% of fire accidents are caused by the non-flammability of textile materials, which greatly limits their development in various fields [1]. As a cellulose fiber, lyocell fiber has structural characteristics such as a high degree of polymerization, a high crystallinity and a high degree of orientation, making it have great mechanical properties, water swelling, flammability, and superior fibrillation.
