Problems solved by technology

However, the weaving materials used in willow crafts are mostly fast-growing and low-quality wood. Even though reactive dyes have good dyeing properties, they are still very susceptible to adverse changes due to external environmental factors after dyeing, among which light, moisture, heat, etc. Both will affect the discoloration and fading of willow crafts after dyeing
Reduce the color fastness of the product, which is not conducive to the improvement of the long-term use value of handicrafts

Embodiment 1

[0018] A processing method for improving the color fastness of reactive dyes on willow handicrafts involves processing the weaving raw materials of willow handicrafts before dyeing, comprising the following steps:

[0019] (1) First, peel the surface of the braided raw material. The peeling method is as follows: prepare a calcium acetate solution with a concentration of 14ppm, add vermiculite particles with a mass fraction of 0.4% to the solution, add the braided raw material, and completely immerse it. Heat up to 72°C, keep stirring under heat preservation for 2 hours, let it stand for 50 minutes, take out the braiding material, refrigerate it at 1°C for 10 hours, then return to room temperature, and peel it off;

[0020] (2) After peeling, polish the surface to be smooth, put it in a reaction kettle, add water 2.5 times the volume of the braiding raw material into the reaction kettle, and add 1.3 grams of magnesium dihydrogen phosphate and 0.6 grams of sodium glutamate to eac...

[0027] A processing method for improving the color fastness of reactive dyes on willow handicrafts involves processing the weaving raw materials of willow handicrafts before dyeing, comprising the following steps:

[0028] (1) First, peel the surface of the braided raw material. The peeling method is as follows: prepare a calcium acetate solution with a concentration of 16ppm, add vermiculite particles with a mass fraction of 0.45% to the solution, add the braided raw material, and completely immerse it. Heat up to 73°C, keep stirring under heat preservation for 2.5 hours, let it stand for 55 minutes, take out the braiding material, refrigerate at 3°C ​​for 11 hours, then return to room temperature, and peel it off;

[0029] (2) After peeling, polish the surface to be smooth, put it in a reaction kettle, add water 3.0 times the volume of the braiding raw material into the reaction kettle, and add 1.5 grams of magnesium dihydrogen phosphate and 0.7 grams of sodium glutamate to e...

[0036] A processing method for improving the color fastness of reactive dyes on willow handicrafts involves processing the weaving raw materials of willow handicrafts before dyeing, comprising the following steps:

[0037](1) First, peel the surface of the braided raw material. The peeling method is as follows: prepare a calcium acetate solution with a concentration of 18ppm, add vermiculite particles with a mass fraction of 0.5% to the solution, add the braided raw material, and completely immerse it. Heat up to 75°C, keep stirring for 3 hours under heat preservation, let stand for 60 minutes, take out the weaving raw material, refrigerate at 5°C for 12 hours, then return to room temperature, and peel it off;

[0038] (2) After peeling, polish the surface smooth, put it in the reactor, add water 3.5 times the volume of the braiding raw material into the reactor, and add 1.7 grams of magnesium dihydrogen phosphate and 0.8 grams of sodium glutamate to each kilogram of water , 0...

Abstract

The invention relates to the technical field of wicker handicraft treatment, and discloses a processing method for improving the color fastness of reactive dyes on wicker handicraft. The processing method for improving the color fastness of the reactive dyes on the wicker handicraft comprises the following steps of processing a wicker handicraft weaving raw material before dyeing, carrying out functional improvement on the wicker handicraft weaving raw material, and carrying out heat treatment with an external reagent. The aging resistance of the surface of the weaving material is remarkably improved, the hydrophobicity and the acid and alkali resistance of the material are improved, the contact angle between the material and water is increased to 130 degrees, the hydrophobicity is improved by more than one time, the quality cannot be lost under acid liquor soaking, the dimensional stability of the modified weaving material is remarkably improved, and the dry shrinkage rate and the wetexpansion rate are reduced. Through a 500-hour ultraviolet aging test, the change values of the brightness, the red-green index and the yellow-blue index of the modified material are lower than the change values of the brightness, the red-green index and the yellow-blue index of of an unmodified material by 30 percent or above, the ultraviolet aging resistance is still good under alkaline and high-temperature conditions, the total color difference value is lower than 0.6, and the effect of improving the color fastness of the reactive dye on the weaving material is further achieved.

Description

technical field [0001] The invention belongs to the technical field of wicker handicraft processing, and in particular relates to a processing method for improving the color fastness of reactive dyes on wicker handicrafts. Background technique [0002] Willow is one of the traditional Chinese folk handicrafts. In ancient times, it was only used as an ordinary daily utility, and it did not rise until the last few decades of the 20th century, and it gradually became an item for export in some parts of China. There are three major willow weaving production bases in the country, Hubei, Shandong, and Anhui (in addition, Henan is also rich in willow weaving). [0003] On June 7, 2008, willow weaving was approved by the State Council to be included in the second batch of national intangible cultural heritage list. [0004] In order to meet the higher pursuit of artworks, the use of dyeing technology can give full play to the creative space of wicker handicrafts, and create shapes...
