Problems solved by technology

[0003] However, plant dyeing was carried out before the development of tap water, and it is a traditional technical method that has been passed down directly after the development of tap water, so it does not take into account the fact that dyed cloth is bleached by chlorine.
In addition, for the polyphenol processing technology developed in recent years, in commercial practice, chlorine resistance is not required for general end customers, and chlorine resistance is rarely required except for special purposes such as swimwear used in swimming pools. sex-related technology research
Based on the above, in vegetable dyeing and polyphenol processed fibers, although the color fastness to light, washing, perspiration, friction and other items have been studied, no attention has been paid to the durability to chlorine, and there is no research on the chlorine fastness. adequate research on the improvement of

Embodiment

[0044] Polyphenol-processed fibers (samples 1-5), polyphenol-processed fibers (samples 1A, 2A-2C, 3A-6A) subjected to a fixation treatment with phenylamide were prepared by the following operations, and commercially available The polyphenol-processed fibers (samples 7-9) treated with the color-fixing agent were investigated for chlorine fastness and whether the color of polyphenols changed.

[0045] (sample 1)

[0046] 1 kg of the scour-bleached cotton fabric is immersed in about 15 L of water in the dyeing bath so that it is fully impregnated with water. Here, 100 g of a cationic agent (trade name: Kachinonon KCN, quaternary ammonium salt manufactured by Katiosha Oil Industry Co., Ltd.) was added, followed by stirring for 10 minutes. Further, after dissolving 20 g of sodium hydroxide in about 1 L of water to prepare a solution, it was added to a dye bath and stirred for 10 minutes. Add about 3L of water to adjust the amount of liquid in the dyeing bath to 20L, heat up to 80...

Abstract

The invention provides a method for preparing polyphenol processing fiber. The method is characterized in that the fiber contacted with polyphenol is treated by using anionic aqueous dispersion of phenyl amide compound. The method can improve the chlorine fastness without losing the light fastness of the polyphenol processing fiber and the like.

Description

technical field [0001] The present invention relates to a method for producing polyphenol-processed fibers. By dyeing polyphenol compounds, which are natural components contained in plants, etc., dyeing with high color fastness can be imparted to fibers. A method for preparing polyphenol-processed fibers that can ensure good dyeing and have chlorine fastness by washing with tap water that does not contain chlorine caused by chemicals or the like. Background technique [0002] Polyphenol compounds contained in plants etc. are used as natural pigments in traditional plant dyeing that has been handed down since ancient times. In addition, in recent years, a processing technology has been developed to immobilize polyphenols on fibers and impart their functional properties (antibacterial properties, etc.) to fibers: 1) Dip dyeing processing methods based on binder resins, 2) Using industrial metals Metal mordanting method with salt, 3) Dip dyeing method using cationic polymer, e...
