Abstract

The invention discloses a preparation method of a composite yarn containing metal organic skeleton nanometer fibers and belongs to the technical field of fiber materials. The preparation method comprises the following steps: taking metal salt and mixing with an organic ligand to prepare the metal organic skeleton nanometer fibers; taking the metal organic skeleton nanometer fibers, preparing to obtain suspension liquid, placing coarse yarns in the suspension liquid and preparing the composite yarn containing the metal organic skeleton nanometer fibers through impregnation, twisting and compound treatment. The composite yarn has the characteristics that the specific surface area of a metal-organic framework nanometer fiber material is large, and active sites are more, and can be used for preparing a fabric with functions of moisture and sweat conduction, detoxification, antibiosis and fluorescence sensing.

Description

technical field [0001] The invention relates to nanofiber yarns, and belongs to the technical field of fiber materials, in particular to a method for preparing composite yarns containing metal-organic framework nanofibers. Background technique [0002] In textile science, yarn is an aggregate of fibers with different twists and bundles, which can give full play to the performance characteristics of various textile fibers, and it is also the basic structural unit for textiles. Therefore, improving the performance of fiber yarn is of great significance to the diversification of textiles and the improvement of added value. [0003] Yarns with different functions can be obtained by post-finishing and blending methods. Among them, blending has the characteristics of green process, diverse processes, and has become the most important method to obtain functional yarns. Fibers with different properties and structural characteristics can be blended yarns through carding, twisting a...
