Example Embodiment

[0034] Example 1

[0035] (1) Prior to viscose fiber yarns: Immersion regenerated cellulose fabric in the pretreatment solution, the concentration of each component in the treatment liquid is: pure base 2g / L, penetrant JFC 0.5 g / L, water resonance Among them, the temperature is 70 ° C, the time is 10 min;

[0036] (2) Preparation of anti-yellow yarn, anti-yellow finishing agent (phenolic oxidant, phosphite mass ratio 6: 1, polyether emulsifier quality is 0.2% of the mass of anti-yellow finishing agent) Dosage is 3% , PH = 5.0 (adjusted by acetic acid or citric acid), the bath ratio of 1: 40, 60 ° C for 3 h, washed repeatedly with deionized water, and the modified yarn of the anti-yellow finishing agent was obtained.

[0037](3) Preparation of antibacterial yarn: Precursted yarns placed in cyclodextrin and citric acid solution (cyclodextrin concentration of 40 g / L, crosslinking agent citric acid is 25 g / L), temperature rise to 80 After the treatment was 60 min, the β-CD / y...

Example Embodiment

[0042] Example 2

[0043] (1) Treatment of Mordale Fiber Yar: Immersion the regenerated cellulose fabric in the previous treatment solution, the concentration of each component in the treatment liquid is: pure base 2g / L, penetrant JFC 0.5 g / L, water rate; The temperature is 70 ° C, the time is 10 min;

[0044] (2) Preparation of anti-yellow yarn, the anti-yellow finishing agent (same as in Example 1) is 3%, pH = 5.0 (adjusted by acetic acid or citric acid), the bath ratio is 1: 30, 60 ° C for 3 h, Deion water is repeatedly cleaned and dried to obtain a yarn to modify the anti-yellow finishing agent;

[0045] (3) Preparation of antibacterial yarn: Precursted yarns placed in cyclodextrin and citric acid solution (cyclodextrin concentration of 40 g / L, crosslinking agent citric acid is 25 g / L), temperature rise to 80 After the treatment was 60 min, the β-CD / yarn was obtained after washing. The modified fibers were placed in a copper sulfate solution of 10 g / L, and the bath...

[0050] Example 3

[0051] (1) Temperature treatment: Immersion of the regenerated cellulose fabric in the pretreatment solution, the concentration of each component in the treatment liquid is: pure base 2 g / L, penetrant JFC 0.5 g / L, water rate; Among them, the temperature is 70 ° C, the time is 10 min;

[0052] (2) Preparation of anti-yellow yarn, the anti-yellow finishing agent (same as in Example 1) is 3%, pH = 5.0 (adjusted by acetic acid or citric acid), the bath ratio is 1: 30, 60 ° C for 3 h, Deion water is repeatedly cleaned and dried to obtain a yarn to modify the anti-yellow finishing agent;

[0053] (3) Preparation of antibacterial yarn: Precursted yarns placed in cyclodextrin and citric acid solution (cyclodextrin concentration of 40 g / L, crosslinking agent citric acid is 25 g / L), temperature rise to 80 After the treatment was 60 min, the β-CD / yarn was obtained after washing. The modified yarn was placed in a copper sulfate solution of 10 g / L, and the bath r...

Abstract

The invention relates to a preparation method of an antibacterial and anti-yellowing regenerated cellulose fabric. The method comprises the steps of anti-yellowing finishing agent modified yarn preparation, beta-CD/yarn preparation, antibacterial yarn preparation and antibacterial and anti-yellowing regenerated cellulose fabric preparation. The method is green and environment-friendly, the process is simple, the cost is low, and the prepared fabric has good yellowing resistance and antibacterial property and has good application prospects in the textile industry.

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...
