Problems solved by technology

[0002] Willow is an important raw material for willow weaving. It grows rapidly, has strong adaptability, good flexibility, and smooth handle. It is often used to weave baskets, but the color of willow is monotonous, which can no longer meet the needs of people who have high requirements for quality of life. Although there is Qi Liu dyeing technology at present, its color fixation effect is poor, it is very easy to fade after dyeing, and the light resistance is poor, which reduces its visual sense and use quality; Greatly improve the use value and economic benefits of willow products

Embodiment 1

[0016] In the embodiment of the present invention, a kind of dyeing method that strengthens the color fastness to light of Chinese wolfberry, concrete method is as follows:

[0017] (1) Defoliate the harvested willow bark willow, immerse in a 5% magnesium sulfate aqueous solution for 70 minutes, take it out, put it in a constant temperature steam treatment at 280 °C for 18 minutes, and heat it at 8 °C / min The cooling rate was lowered to 180°C and continued to be treated with constant temperature steam for 15 minutes to obtain pretreated willow bark;

[0018] (2) Submerge the pretreated bark willow in the dyeing agent for 54 minutes and pass it through the ultrasonic wave for ultrasonic treatment, take it out, put it into the vacuum treatment for 24 minutes under the condition of temperature Microwave drying under the condition of 850MHz to a moisture content of 4% to obtain dyed willow;

[0019] The dyeing agent is made of the following raw materials in parts by weight: 0.7 p...

Embodiment 2

[0025] In the embodiment of the present invention, a kind of dyeing method that strengthens the color fastness to light of Chinese wolfberry, concrete method is as follows:

[0026] (1) Defoliate the harvested willow bark willow, immerse in an aqueous solution of magnesium sulfate with a mass fraction of 6% for 75 minutes, take it out, put it into a constant temperature steam treatment at a temperature of 285°C for 19 minutes, and heat it at a temperature of 8.5°C / min. The cooling rate was lowered to 185°C and continued to be treated with constant temperature steam for 16 minutes to obtain pretreated willow bark;

Abstract

The invention belongs to the technical field of osier dyeing, in particular to a dyeing method for improving color fastness to light of osier. The method specifically comprises the following steps of (1) osier pretreatment and (2) osier dyeing. The permeation of a coloring agent is effectively improved, the degree of aggregation of dye molecules is higher, crosslinking binding between the dye molecules and the ingredients of osier is prompted, the binding force is high, leachability resistance is good, the electronic cloud density of azo group hydrogen atoms is reduced, the shielding effect on azo groups is achieved, the photooxidation resistance stability of the azo groups in the structure of the dye molecules is improved, and finally, the color fastness to light of a dye is improved; and furthermore, osier is evenly dyed and has good color fastness to water, the difference between the color of the interior and the color of the exterior of osier is small, osier is evenly dyed without stains, and is bright and glossy, and the quality of the wickerwork made of osier is effectively improved.
