高温处理对不同聚酰亚胺含量隔热絮片服用性能的影响
Effect of high temperature treatment on clothing performance of thermal insulation floccule with different polyimide content
摘要
Abstract
In order to more reasonably select and design polyimide floccules used in thermal protection clothing,a series of high temperature treatments were conducted on PI thermal insulation floccules,PI/PET 50/50 thermal insulation floccules and PI/PET 15/85 thermal insulation floccules.The appearance,thickness change,thermal insulation performance,air permeability and moisture permeability of the three thermal insulatio floccules before and after high temperature treatments were tested and analyzed.Results showed that PI thermal insulation floccule was the most stable,with no significant changes in appearance after high temperature treatments,the thickness and thermal insulation performance were increased,the moisture permeability and air permeability were slightly reduced.After PI/PET 50/50 thermal insulation floccules treated in 260℃,its thickness,thermal insulation performance and air permeability were increased,while its moisture permeability was decreased slightly.After PI/PET 15/85 thermal insulation floccules treated in 260℃,the floccules were severely coked,its thickness and thermal insulation performance were increased,the moisture permeability and air permeability were decreased.It is considered that the PI/PET 50/50 thermal insulation floccules reinforced by hot air method was both insulating and comfortable,which had a certain application prospect in the field of thermal protection clothing.关键词
