Embodiment 1

[0017] Preparation of embodiment 1 photochromic fabric

[0018] 1. Preparation of photosensitizer

[0019] A 20% ferric ammonium citrate solution and an 8% potassium ferricyanide solution were prepared, and then the two solutions were mixed at a weight ratio of 1:1 to prepare a photosensitizer.

[0020] The two solutions can be mixed immediately after mixing, or they can be stored in a dark place for 24 hours before mixing. Before mixing, they can be stored separately in a dark container away from light for a period of time, and the service life of the mixed solution will be shortened to 2 weeks.

[0021] When exposed to light, ferric ammonium citrate will undergo a reduction reaction to produce F 2+ , and Fe 2+ It can further react with potassium ferricyanide to produce a substance called Teng's blue.

[0022] 2. Preparation of sodium alginate paste

[0023] Prepare the original paste: put 400ml of warm water in a beaker at 10°C, weigh 5g of sodium hexametaphosphate, dis...

Embodiment 2

[0037] Preparation of embodiment 2 photosensitive color-changing fabric

[0038] 1. Preparation of photosensitizer

[0039] Prepare a ferric ammonium citrate solution with a concentration of 18% and a potassium ferricyanide solution with a concentration of 6%, and then mix the two solutions at a weight ratio of 1:1 to prepare a photosensitizer.

[0040] 2. Preparation of sodium alginate paste

[0041] Prepare the original paste: fill a beaker with 400ml of warm water at 80°C, weigh 4g of sodium hexametaphosphate, dissolve it in warm water, then weigh 40g of sodium alginate dry powder, sprinkle while stirring, and let it stand after sprinkling. Leave overnight to fully puff the paste. The viscosity of sodium alginate raw paste is 10000-200000cps.

[0042] 3. Preparation of photosensitive printing paste

[0043] The photosensitizer is mixed with sodium alginate raw paste, urea, glycerin, ammonium sulfate, sodium chlorate and emulsifier to prepare photosensitive printing past...

Embodiment 3

[0053] Embodiment 3 Preparation of photosensitive color-changing fabric

[0054] 1. Preparation of photosensitizer

[0055] A 24% ferric ammonium citrate solution and a 10% potassium ferricyanide solution were prepared, and then the two solutions were mixed at a weight ratio of 1:1 to prepare a photosensitizer.

[0056] 2. Preparation of sodium alginate paste

[0057]Prepare the original paste: fill a beaker with 850ml of warm water at 40°C, weigh 10g of sodium hexametaphosphate, dissolve it in warm water, then weigh 100g of sodium alginate dry powder, sprinkle it into the water, and stir it while sprinkled. Then continue to stir until it is uniform, and it will be uniform and transparent after the configuration is completed. The viscosity of sodium alginate raw paste is 10000-200000cps.

[0058] 3. Preparation of photosensitive printing paste

[0059] The photosensitizer is mixed with sodium alginate raw paste, urea, glycerin, ammonium sulfate, sodium chlorate and emulsif...

Abstract

The invention provides a light-sensitive color-changing fabric and a production process thereof. The production process comprises the steps of pulp preparation, pulp scraping and air-drying. Accordingto the technical scheme, direct printing is combined to an indigo dyeing technology, a photosensitizer is added in printing pulp to prepare light-sensitive printing pulp, by pulp scraping, the light-sensitive printing pulp is printed on a fabric through a silk-screen plate, and thus, printed patterns are shown. In a printing process, the fabric is not exposed, and is packed with an ultraviolet-proof film packing bag. When a consumer takes the printed fabric from a packing bag, the printed fabric is in a certain color, but the color of the printed patterns gradually becomes blue after the printed fabric is illuminated for a period of time, finally, different parts of clothes are in deep-light changing and hierarchical blue color due to difference of illumination time or difference of natural abrasion degrees, and the color-changing fabric or garment meets the personalized market requirement, and shows natural, random and simple aesthetic perception.

Description

technical field [0001] The invention relates to the textile field, in particular to a photosensitive color-changing fabric and a production process thereof. Background technique [0002] Indigo dyeing is an ancient printing and dyeing process, which first appeared in the Qin and Han Dynasties. People discovered that plants can be used to dye fabrics, and this method can be used to dye fabrics with good luster. However, if one wants to produce indigo-dyed products with unique charm, it may take ten years or more. The production process of indigo dyeing is not only complicated and cumbersome, but also requires a lot of cost, and the design sense and patterns it can present are very limited, and it is difficult to keep up with the development of the times. Contents of the invention [0003] Therefore, it is necessary to provide a new process to make up for the time-consuming problem in the indigo dyeing process. The fabric changes color according to the user's use, which is ...
