  Abstract

Affected by thermophysical parameters and basic fabric parameters, thermal protection, thermal and moisture comfort and wearability of thermal protective clothing present opposite representation. To balance the contradiction, a hollow structure is proposed for thermal barrier, including covered skin, cavity and pillar. This three-layer structure is formed by middle layer composed of cavity and pillar wrapped by covered skin upper and lower. The whole structure is composed of fibers, and cavity and pillar with different bulk density is evenly distributed in meddle layer. This hollow structure can be obtained by pretreating, needle punching, washing and drying of polyvinyl alcohol/thermal materials composite felt due to the characteristic of water-soluble of polyvinyl alcohol. Through the preparation and comprehensive evaluation of hollow structure thermal barrier, it is found that hollow structure thermal barrier proposed has higher TPP value, lower moisture resistance, higher air permeability and higher softness compared with solid structure. Meanwhile, quality evaluation index of hollow structure is improved through the hierarchical evaluation model, which has a guiding and reference significance for the development of hollow thermal protective fabrics.
