Problems solved by technology

Good heat resistance and acid resistance, very stable in the pH range of 2-7, easy to oxidize and brown under alkaline conditions; due to the large amount of sodium hydroxide contained in the spinning solution in the production process of viscose fiber, the early stage of the process is large Part of it is an alkaline environment, therefore, the viscose fiber prepared by adding tea polyphenols directly into the spinning solution will produce greater discoloration and greater color difference, especially when the concentration of sodium hydroxide produces a slight When changing, the color difference of the fiber will continue to change, and the same batch will also produce different color difference problems, resulting in extremely unstable quality of the prepared tea polyphenol fiber

Abstract

The invention provides anti-browning tea polyphenol modified viscose. The anti-browning tea polyphenol modified viscose is characterized in that the content of tea polyphenol is 1-5%, and the moisturerate is 11.3-12.2%. The prepared anti-browning tea polyphenol modified viscose has low color difference, and high dyeing stability and heat preservation performance; and an anti-browning tea polyphenol modification agent preparation pre-treatment method is adopted, thus the prepared anti-browning tea polyphenol modified viscose can prevent browning, and the color difference of the viscose in thesame batch is small.

Description

technical field [0001] The invention relates to a tea polyphenol modified viscose fiber, in particular to an anti-browning tea polyphenol modified viscose fiber, which belongs to the field of cellulose fiber preparation. Background technique [0002] Functional and differentiated fibers are the main development direction of fibers in recent years, such as graphene fibers, protein fibers, wormwood fibers, etc., using mixing or post-processing methods, adding functional substances or fiber preparations during fiber preparation After completion, the post-treatment process finally makes the prepared fibers present different characteristics to meet the needs of different customers. [0003] For example, the Chinese patent number is: CN201810553400.3 discloses a preparation process of tea polyphenol modified viscose fiber, using commercially available tea polyphenols and viscose fiber as raw materials, and pretreating viscose fiber by preparing surfactant to prepare fiber The ste...
