Photochromic master batch for fiber core layer with skin-core structure and preparation method of photochromic master batch

Abstract

The invention provides a photochromic master batch for a fiber core layer with a skin-core structure. The photochromic master batch is composed of the following components in parts by weight: 0-90 parts of a carrier, 1-30 parts of photochromic powder, 0-20 parts of a dye, 0.5-2.5 parts of a mixture and 0.5-1.5 parts of a dispersing aid, wherein the carrier and a core layer fiber of the skin-core structure fiber are polymers of a same type, and the mixture comprises a heat stabilizer and an antioxidant. The invention further provides a preparation method of the photochromic master batch for thefiber core layer with the skin-core structure. The photochromic master batch disclosed by the invention is suitable for production of skin-core structure fibers, so that a fabric manufactured by thefibers has a photochromic characteristic; besides, as the carrier of the photochromic master batch and the core layer fiber of the sheath-core structure fiber are polymers of the same type, the carrier can have good compatibility with the core layer fiber, the dyeing performance of the core layer fiber is improved thermally, the photochromic material can be effectively prevented from falling off,and the water washing resistance and the wear resistance of the sheath-core structure fiber are improved.

Description

technical field [0001] The invention relates to a photochromic masterbatch for a fiber core layer of a skin-core structure and a preparation method thereof. Background technique [0002] Most of the common fibers in the prior art are uncolored primary white fibers. When obtaining colored fibers, the primary white fibers need to be dyed. Now there are two ways to obtain colored fibers: one is the traditional printing and dyeing method, and the other is the masterbatch dope coloring method that has developed rapidly in the past two decades. Among them, the printing and dyeing method is gradually being replaced by the masterbatch stock solution coloring method because it will generate a large amount of colored wastewater and consume a lot of energy. [0003] As people's demand for textiles has gradually changed from practicality to diversity and functionality, especially people's psychology of seeking differences in textiles is increasing, the emergence of color-changing texti...

Problems solved by technology

However, most of the existing photochromic fabrics are obtained by coating, but this kind of fabric has poor coating fastness, poor air permeability, hard hand feeling, affects use, and brings certain environmental pollution
