example 1

[0019] First select perlite for construction, rinse it with water for 5 times, and then dry it at 80°C for 3 hours. After the drying is completed, put it in a plastic basin with a diameter of 80 cm, and then add Hoagland Put the nutrient solution into the plastic basin, make it just cover the surface of the perlite, and soak for 24 hours; then spread the star grass seeds evenly on it, set the temperature at 25°C, the light intensity at 65KLux, and control the air humidity at 75%, so that Seeds germinate and grow to the second-leaf stage, then add 3mL per plant dropwise, and slowly add 0.5% sodium carbonate solution to the bottom of Stargrass with a funnel, add once every 24h, and increase the carbonic acid concentration after every 5 days The concentration of 0.5% sodium solution was continued to be added dropwise until the concentration was 3%. After the dropwise addition of 5 days, the dropwise addition of the sodium carbonate solution was stopped; pH is 7.8 in the phosphate...

[0021]First select perlite for construction, wash it with clean water 3 times, and then dry it at 60°C for 2 hours. After the drying is completed, put it in a plastic basin with a diameter of 60cm, and then add Hoagland Put the nutrient solution into the plastic basin, make it just cover the surface of the perlite, and soak for 20 hours; then spread the star grass seeds evenly on it, set the temperature at 20°C, the light intensity at 65KLux, and control the air humidity at 72%, so that The seeds germinate and grow to the second-leaf stage, then add 2 mL per plant dropwise, and slowly add a 0.5% sodium carbonate solution to the bottom of the star grass with a funnel, add once every 24 hours, and increase the carbonic acid after every 4 days The concentration of 0.5% sodium solution was continued to be added dropwise until the concentration was 3%. After 4 days, the dropwise addition of sodium carbonate solution was stopped; after the addition was completed, the collected star g...

Abstract

The invention relates to a method for preparing a puccinellia tenuiflora nanometer slow release alkali-resistant penetrating agent and belongs to the technical field of fabric dyeing and finishing. The method comprises the steps of cultivating puccinellia tenuiflora with a special method, picking leaves to prepare a puccinellia tenuiflora alkali-resistant enzyme solution after the two-leave period, then making the solution react with emulsion chitosan powder, ethanediol and other substances in a cross-linking mode to obtain puccinellia tenuiflora nanometer slow release alkali-resistant particles, and finally making the puccinellia tenuiflora nanometer slow release alkali-resistant particles react with isooctanol polyethenoxy ether and other substances under a certain condition. The method has the advantages that the alkali-resistant strength of the prepared penetrating agent is over 200 g / L, permeability is extremely high, and the method can be widely applied to pretreatment of cotton, linen and cotton and linen blended fabrics.

Description

technical field [0001] The invention relates to a preparation method of star grass nano slow-release alkali-resistant penetrating agent, which belongs to the technical field of fabric dyeing and finishing. Background technique [0002] The full name of penetrant (JFC) is fatty alcohol polyoxyethylene ether, which belongs to nonionic surfactant. Penetrant, as its name implies, plays a penetrating role. It also has fixed hydrophilic and lipophilic groups, which can be aligned on the surface of the solution and can significantly reduce the surface tension. [0003] At present, the cotton, hemp and their blended fabrics to be printed and dyed are usually treated before printing and dyeing to remove impurities such as sizing and fiber symbiosis on the fabric, so as to obtain ideal whiteness and capillary effect. Generally, caustic soda, penetrating agent, The scouring agent, stabilizer and hydrogen peroxide are used to desizing, scouring and bleaching the fabric. The alkali resi...
