Embodiment 1

[0030] Embodiment 1: the treatment of composite sol of cotton-nylon blended woven fabric with monochromatic color block inkjet printing with paint ink

[0031] 58 parts of propanol, 21 parts of tetraethyl orthosilicate and 10 parts of water were successively added into the Erlenmeyer flask. Stir on a magnetic stirrer (400rpm) for 20min, under this condition, add 2 parts of hydrochloric acid with a concentration of 0.01mol / L to the above solution at a rate of 40drop / min, stir for 2h, and then add tetraethyl titanate 9 share. Adjust the rotation speed of the magnetic stirrer (700rpm), stir continuously at room temperature for 24h, and let it stand and age for 2 days. With the above SiO 2 / TiO 2 The composite sol is used to pad the monochrome color block of the inkjet printing of the cotton-nylon blended fabric with two dipping and two padding. Bake for 8 minutes.

Embodiment 2

[0036] Embodiment 2: the processing of the composite sol of pure cotton knitted fabric with inkjet printing of paint ink

[0037] 46 parts of ethylene glycol, 22 parts of methyl orthosilicate and 22 parts of water were successively added into the Erlenmeyer flask. Stir on a magnetic stirrer (500rpm) for 20min. Under this condition, add 4 parts of acetic acid with a concentration of 0.01mol / L to the above solution dropwise at a speed of 70drop / min. After stirring for 2h, add tetra-n-butyl titanate 6 servings. Adjust the rotating speed of the magnetic stirrer (1000rpm), stir continuously at room temperature for 24h, and let it stand for aging for 2 days. SiO prepared above 2 / TiO 2 The composite sol is used to impregnate the inkjet printed knitted fabric with paint ink: the liquor ratio is 1:30, the temperature is 50°C, and the treatment time is 10 minutes. The fabric was prebaked at 60°C for 30 minutes and then baked at 170°C for 5 minutes.

Embodiment 3

[0039] Embodiment 3: Treatment of composite sol for inkjet printing polyester light box cloth with coating ink

[0040]41 parts of ethanol, 26 parts of orthobutyl silicate and 17 parts of water were successively added into the Erlenmeyer flask. Stir on a magnetic stirrer (800rpm) for 10min, under this condition, add 5 parts of nitric acid with a concentration of 0.01mol / L to the above solution dropwise at a speed of 30drop / min, stir for 2h, and then add tetrapropyl ortho titanate 11 servings. Adjust the rotation speed of the magnetic stirrer (300rpm), stir continuously at room temperature for 24h, and let it stand and age for 2 days. SiO prepared above 2 / TiO 2 The composite sol is used to impregnate the polyester light box cloth printed with paint ink and inkjet printing: the liquor ratio is 1:50, the temperature is 60°C, and the treatment time is 8 minutes. The light box cloth is pre-baked at 60°C for 25 minutes and then baked at 110°C for 15 minutes.

Abstract

The invention discloses a preparation method of SiO2 / TiO2 composite sol used for improving inkjet printing fastness, belonging to the textile chemical engineering technology field. The invention uses the precursors of silicon and titanium, solvent, catalyst and water to prepare the composite sol. As the composite sol is used, the dye fixation is convenient and the formed network structure in the composite sol film is denser. The film forming ability of composite sol is better than that of single sol. The dry and wet rubbing fastness, the soaping fastness, the light fastness, and the like of inkjet printing base fabric of coating ink are improved. And with the method used, no metal ions of Cu<2+>, Cr<3+>, and the like can be introduced and no pollution is made to the environment.

Description

technical field [0001] The invention belongs to the technical field of textile chemical industry, and in particular relates to a SiO used to improve the fastness of inkjet printing 2 / TiO 2 Preparation method of composite sol. Background technique [0002] Digital inkjet printing technology uses a computer-controlled printing system to spray special dyes or paints directly on fibers or other base fabrics to print various patterns and patterns. Now digital inkjet printing technology is widely used in textile, clothing, advertising and other industries. Now the development of the garment industry is promoting the progress of digital inkjet printing technology, which is widely used in traditional printing proofing, modern personalized clothing design and other fields. The "flexible", non-contact, and instant printing characteristics of inkjet printing technology on the one hand have created the convenience and quickness of clothing design and the characteristics of bright co...
