Embodiment 1

[0035] (1) Pretreatment of viscose fiber yarn: soak the regenerated cellulose fabric in the pretreatment solution, the concentration of each component in the treatment solution is: soda ash 2g / L, penetrant JFC 0.5g / L, water balance; Wherein, the temperature is 70°C, and the time is 10 minutes;

[0036] (2) Preparation of anti-yellowing yarn, anti-yellowing finishing agent (the mass ratio of phenolic oxidant and phosphite is 6:1, the quality of polyether emulsifier is 0.2% of the quality of anti-yellowing finishing agent solution) consumption is 3% , pH = about 5.0 (adjusted by acetic acid or citric acid), bath ratio 1:40, react at 60°C for 3 hours, wash repeatedly with deionized water, and dry to obtain yarn modified by anti-yellowing finishing agent;

[0037](3) Preparation of antibacterial yarn: place the pretreated yarn in cyclodextrin and citric acid solution (the concentration of cyclodextrin is 40g / L, and the dosage of crosslinking agent citric acid is 25g / L), and the te...

Embodiment 2

[0043] (1) Pretreatment of modal fiber yarn: soak the regenerated cellulose fabric in the pretreatment solution, the concentration of each component in the treatment solution is: soda ash 2g / L, penetrant JFC 0.5g / L, water balance; , the temperature is 70°C, and the time is 10min;

[0044] (2) Preparation of anti-yellowing yarn, the dosage of anti-yellowing finishing agent (same as Example 1) is 3%, pH=about 5.0 (adjusted by acetic acid or citric acid), bath ratio 1:30, reacted at 60°C for 3h, and used Repeated washing with deionized water and drying to obtain yarn modified with anti-yellowing finishing agent;

[0045] (3) Preparation of antibacterial yarn: place the pretreated yarn in cyclodextrin and citric acid solution (the concentration of cyclodextrin is 40g / L, and the dosage of crosslinking agent citric acid is 25g / L), and the temperature is raised to 80 After treatment at ℃ for 60 minutes, β-CD / yarn was obtained by washing and baking. The modified fibers were placed i...

Description

technical field [0001] The invention belongs to the technical field of textile functional finishing, and in particular relates to a preparation method of an antibacterial and anti-yellowing regenerated cellulose fabric. Background technique [0002] Regenerated cellulose fiber is a kind of cellulose fiber, which is harmless to ecology and environment, and is green and environmentally friendly. It combines the luxurious texture of natural fibers with the practicability of synthetic fibers. It has the softness of cotton, silk-like feel, lightness, breathability and other properties, and the fabric color is bright and full. It can be blended and interwoven with a variety of fibers (such as cotton, linen, silk, etc.) to improve the quality of these fabrics and achieve better clothing use effects. However, regenerated cellulose fabrics are prone to surface yellowing due to the effects of light, high temperature, and chemical substances during wet finishing and wearing, such as h...
