Embodiment 1
[0024] Weigh 1000 grams of Tibetan blue fruit, grind it mechanically, add it to an aqueous solution with a pH value of 12 at 20 times, adjust the pH value of the solution with sodium phosphate, raise the temperature to 95°C, keep it warm for 60 minutes, and filter; Sodium phosphate solution of 12 was leached for 30 minutes, filtered, and the two extracts were combined, concentrated, solidified, and pulverized to obtain a powdery solid.
Embodiment 2
[0026] Weigh 1000 grams of Tibetan blue fruit, grind it mechanically, add it to an aqueous solution with 10 times the pH value of 8, adjust the pH value of the solution with sodium bicarbonate, heat up to 100°C, keep it warm for 90 minutes, and filter; continue to use 5 times the water and pH value of the filter residue Sodium bicarbonate solution of 8 was leached for 45 minutes, filtered, and the two extracts were combined, concentrated, solidified, and pulverized to obtain a powdery solid.
Embodiment 3
[0028] Weigh 1000 grams of Tibetan blue fruit, crush it mechanically, add it to an aqueous solution with 5 times the pH value of 10, adjust the pH value of the solution with sodium carbonate, heat up to 100°C, keep it warm for 75 minutes, and filter; 10% sodium carbonate solution for 40 minutes, filtered, combined the two extracts, concentrated, solidified, and pulverized to obtain a powdery solid.
[0029] 2. The use of the finishing agent with the function of removing formaldehyde extracted from Tibetan blue fruit:
[0031] ① Soak the cotton fabric in water to moisten it, take it out and squeeze it dry, and set it aside.
[0032] ②The cotton fabric is modified according to the following formula: the concentration of modifier DT is 5% of the weight of the object to be treated, NaOH 2g / L, the bath ratio is 1:15, the temperature is 80°C, heat preservation for 30min, fully washed with water, and squeezed dry.

Abstract
The invention discloses a method for extracting, from myrobalan, a finishing agent having a function of removing formaldehyde, and applications thereof. The plant myrobalan is mechanically crushed and added into an aqueous solution which has the pH value of 8-12 and is 5-20 times as much as the plant myrobalan, the pH value of the solution is regulated and then the solution is heated up to 95-100 DEG C, followed by heat preservation for 60-90 minutes and filtration; filtration residues are continued to be leached for 30-45 minutes by a diluted alkaline solution which has the pH value of 8-12 and is 5-10 times as much as the water, the leaching liquor is filtered and combined twice, and powdered solids are obtained by condensation, solidification and crush. The finishing agent is used for the preparation of protein polyamide fiber or textile having the function of removing formaldehyde, or the preparation of cellulose fiber or textile having the function of removing formaldehyde. The invention is simple in extraction technology, which causes no environmental pollution, safe in being worn, which has no carcinogenic, teratogenic effect or causes no allergy, and is excellent in the compatibility with ecological environment and is biologically degradable; the myrobalan is abundant in raw materials and convenient in use, which can be applied not only to clothes textiles, but also to household textiles.
Description
technical field [0001] The invention relates to the preparation of functional textiles, in particular to a method for extracting a finishing agent with a formaldehyde-removing function from Tibetan blue fruit and its application. Background technique [0002] In recent years, with the rapid development of science and technology, the continuous improvement of living standards, and the increasing awareness of health and environmental protection, people are increasingly pursuing a fresh, healthy, hygienic and comfortable living environment. In the past few decades, people have focused their attention on outdoor air pollution and its control, but only in the last ten years have they realized the hygienic significance of indoor air quality. Human beings spend more than 90% of their time indoors, and indoor air quality is closely related to people's lives. [0003] The No. 153 Bulletin issued by the World Health Organization in 2004 determined that formaldehyde is carcinogenic. ...
