Embodiment 1

[0030] Take a certain amount of natural tea pigment (or tea polyphenols or catechins) particles and put them into a high-efficiency stirring grinder for pulverization and refinement to obtain natural tea pigments (or tea polyphenols or catechins) powder with a particle size of less than 150nm granules; take a certain amount of natural tea pigment (or tea polyphenols or catechins) powder in a ratio of 20g / 1000ml and add it into water at a temperature of 20°C for dissolution to make tea pigments (or tea polyphenols or catechins) ) solution.

[0031] The fine powder (or its solution) of the natural tea pigment or tea polyphenol or catechin that makes is added to the viscose spinning stock solution (fiber mass) in the ratio of 1% (or 5%) of the viscose spinning stock solution quality. Fraction is 5%), after high-speed dispersing, let it stand for vacuum defoaming, then according to the conventional wet spinning and spinning process, after metering by the metering pump, enter the 4...

Embodiment 2

[0033]Take a certain amount of natural tea pigment (or tea polyphenols or catechins) particles and put them into a high-efficiency stirring grinder for pulverization and refinement to obtain natural tea pigments (or tea polyphenols or catechins) powder with a particle size of less than 150nm Take a certain amount of natural tea pigment (or tea polyphenol or catechin) powder and add it into water at a temperature of 35°C in a ratio of 30g / 1000ml to dissolve it to make tea pigment (or tea polyphenol or catechin) ) solution.

[0034] The obtained natural tea pigment (or tea polyphenol or catechin) fine powder (or its solution) is added to the viscose spinning stock solution (fiber Mass fraction is 10%), after high-speed dispersion, stand vacuum defoaming, then shape by the similar wet spinning and spinning process of embodiment 1, obtain the viscose fiber with tea antibacterial and deodorant function.

Embodiment 3

[0036] Take a certain amount of natural tea pigment (or tea polyphenols or catechins) particles and put them into a high-efficiency stirring grinder for pulverization and refinement to obtain natural tea pigments (or tea polyphenols or catechins) powder with a particle size of less than 150nm Take a certain amount of natural tea pigment (or tea polyphenol or catechin) powder and add it into water at a temperature of 50°C in a ratio of 50g / 1000ml to dissolve it to make tea pigment (or tea polyphenol or catechin) ) solution.

[0037] The obtained natural tea pigment (or tea polyphenol or catechin) fine powder (or its solution) is added to the viscose spinning stock solution (fiber) in the proportion of 10% (or 20%) of the viscose spinning stock solution quality. Mass fraction is 20%), after high-speed dispersion, stand vacuum defoaming, then form by the similar wet spinning and spinning process of embodiment 1, obtain the viscose fiber with tea antibacterial and deodorant functi...

Abstract

The present invention provides one kind of viscose fiber with antibacterial and antifouling tea component, and the viscose fiber contains antiseptic comprising at least one of natural tea pigment, tea polyphenol and catechin. The powder or solution of at least one of natural tea pigment, tea polyphenol and catechin in the amount of 1-10 wt% is added into viscose spinning fluid to result in lasting antibacterial and antifouling functions. The viscose fiber has also the fragrance of tea, dyeing effect and no side effect on human body, and is suitable for use in making underwear, other costumes and bedding.

Description

technical field [0001] The invention relates to a functional viscose fiber product and a preparation method thereof, in particular to a viscose fiber with tea antibacterial and deodorizing functions and a preparation method thereof. Background technique [0002] Existing viscose fiber is a commonly used regenerated fiber, and its products have good moisture absorption and air permeability, and are comfortable to wear, but they do not have the functions of antibacterial, deodorant and fragrance of tea. With the improvement of people's living standards and the change of life concept, people pay more and more attention to the health care function of textiles. It is hoped that the existing viscose fiber textiles can be improved in terms of antibacterial and deodorizing performance and odor. [0003] Tea pigment is formed by the oxidation of catechin and its derivatives in tea, and its molecular structure maintains the characteristics of the mother nucleus of catechin. Tea pigme...
