Problems solved by technology

Because of its own molecular structure, its dry and wet strength is relatively low. If some fillers (photochromic microcapsule materials) are added inside, the fiber structure will be damaged, resulting in the dry and wet state of the fiber material. The strength is lower, it is difficult to meet the requirements of fabric manufacturing and use

Abstract

The invention relates to a photochromic viscose fiber and a preparation method thereof, belonging to the technical field of textile. The photochromic viscose fiber is prepared from an adhesive, photochromic microcapsules and a fiber reinforced agent, wherein the content of the photochromic microcapsules is 1-20wt%, and the content of the fiber reinforced agent is 0.1-10wt%. The preparation method of the photochromic viscose fiber comprises the following steps: (1) dissolving the photochromic microcapsules and the fiber reinforced agent into water to form dispersed viscose emulsion; (2) feeding the dispersed viscose emulsion into viscose to be spun, and mixing; (3) molding by spinning in an acid bath to obtain a photochromic viscose fiber product. The photochromic viscose fiber is simple and reasonable in components and simple in preparation method; the obtained fiber is uniform in whole color change; the strength of the photochromic viscose fiber reaches or exceeds that of the conventional viscose fiber, so that the demand of fabric manufacture can be met.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a photochromic viscose fiber and a preparation method thereof. Background technique [0002] It has been more than 100 years since human beings discovered the phenomenon of photochromism. Photochromic materials refer to a class of materials that can change color after being excited by a light source. Photochromism refers to the change of the molecular structure of certain compounds under the action of light of a certain wavelength and intensity, resulting in a corresponding change in the absorption peak of light, that is, the color, and this change is generally reversible. [0003] Photochromic materials have the characteristics of sensitive discoloration and bright color, but are easily affected by environmental factors such as temperature, light, pH value and oxygen, resulting in oxidative deterioration and poor fatigue resistance. There is no affinity, which affects its app...
