Abstract

The invention discloses a sponge fiber, a preparation method and an application, and belongs to the field of fiber technology. A sponge fiber is filamentous and its cross-section is a net-like cross-section. The net-like cross-section includes a central part and an edge part located on the periphery of the central part. The average pore diameter of the central part is smaller than that of the edge part. The sponge fiber provided by the invention has a special structure, so it performs well in the fields of sound-insulating materials and heat-retaining materials, and has broad application prospects in the fields of materials that directly contact with the human body and in the technical field of biological scaffold materials.

Description

technical field

[0001] The invention belongs to the technical field of fibers, and in particular relates to a sponge fiber, a preparation method and an application. Background technique

[0002] Due to their good biocompatibility, chitin, chitosan, plant cellulose, bacterial fibers, and their derivatives and regenerated fibers are widely used in the fields of bioscaffold material technology, drug diagnosis technology, and oral pharmacy that simulate the in vitro microenvironment of cells. There are a wide range of applications in the technical field and in the field of materials that are in direct contact with the body (eg wound dressings).

[0003] Currently, there are two main strategies for constructing regenerated fibers, top-down and bottom-up. Among them, the top-down strategy is to spin by using dry spinning, wet spinning, wet extrusion, microfluidic field spinning, dry jet wet spinning and other processing methods. The obtained cellulose fibers generally have the c...
