Abstract

The invention provides a long-acting broad-spectrum antibacterial sky tea fiber, which belongs to the field of cellulose fibers. The fiber is composed of an inner layer and an outer layer; the inner layer is distributed with micro-cavities and carbon nanotubes; the inner layer accounts for 65-75% of the total dry weight of the fiber; the outer layer accounts for the total fiber weight. 25‑35% of weight. The present invention also provides a preparation method of long-acting broad-spectrum antibacterial tiancha fiber. The method includes the preparation step of viscose spinning solution; the preparation step of the viscose spinning solution includes adding a modification aid in the dissolving process. A kind of long-acting broad-spectrum antibacterial sky tea fiber prepared by the present invention, the inner layer adopts the traditional sulfonate method glue making process, adopts the coagulation bath process formed by the skinless core layer, and the outer layer adopts the creative solvent method to homogenize the fiber. After coating and coagulation regeneration, the prepared fibers have high strength, good antibacterial durability, high wet modulus, and especially the dry breaking strength exceeds that of ordinary viscose fibers.

Description

technical field [0001] The invention provides an antibacterial fiber and a preparation method thereof, in particular to a long-acting broad-spectrum antibacterial Tiancha fiber and a preparation method thereof, belonging to the field of cellulose fibers. Background technique [0002] Resources, environment, and sustainable development strategy issues have become global hot issues facing human society, and the requirement for precise and efficient use of biological resources has become a major trend in today's social development. With the gradual depletion of petroleum resources, the development of natural products produced by photosynthesis has become a hot topic today, including primary development with the main goal of developing high-quality and high-yield raw materials, secondary development with the purpose of developing raw material processing, and Three-level development for the purpose of in-depth development of raw materials and their applications. [0003] The exi...
