Problems solved by technology

The technical route adopted by these patents is to use already prepared fiber slices or masterbatches as the basic material, and it is also recorded that solid nanoparticles are doped in the fibers, but the doped solid nanoparticles are only on the basis of the original fiber material. It has a certain thermal insulation performance, but it still cannot meet the requirements of modern people for thermal insulation performance. In addition, these methods are complicated to operate and operate under harsh operating conditions, which is not conducive to wide application and large-scale promotion, and the market promotion ability is weak.

Description

technical field [0001] The invention relates to the field of functional fiber manufacturing, in particular to a heat-insulation fiber and its preparation method and application. Background technique [0002] As we all know, there are three ways of heat conduction: radiation, convection, and conduction. In order to fully improve the heat insulation performance, it is necessary to have three functions of blocking radiation, limiting convection, and extending the conduction path, so as to meet the conditions of extremely excellent heat insulation performance. [0003] At present, thermal insulation textile materials usually achieve the purpose of thermal insulation by filling down, fibers, and cotton in the interlayer. Due to the higher thermal conductivity of the filled material and the larger filling amount, this method makes the prepared thermal insulation products, such as quilts, quilts, clothing tents. It is thick and heavy, and it is extremely inconvenient to carry, an...
