Embodiment 1

[0012] A nano-waterproof, oil-proof and anti-fouling finishing solution includes a fluorine-containing finishing agent for waterproofing, oil-proofing and anti-fouling, and a nano-ceramic powder dispersion. The nano-ceramic powder dispersion liquid comprises deionized, Al 2 o 3 , dispersant, Al per 100ml deionized water 2 o 3 The amount of the dispersant is 5-15g, the amount of the dispersant is 1.2-2.4ml, and the pH value of the nano-ceramic powder dispersion is 8-9. Al per 100ml of deionized water 2 o 3 The amount of the dispersant is 10g, the amount of the dispersant is 2ml, and the pH value of the nano-ceramic powder dispersion is 8.5. The preparation process of the nano-ceramic powder dispersion liquid is: first Al 2 o 3 Dissolve in deionized water, then drop into dispersant, then drop into ammonia water to adjust the pH value to 8~9, and finally carry out ultrasonic treatment. It also includes crosslinking agent, penetrating agent, citric acid, 30~60g of fluorine...

Embodiment 2

[0014] The difference from Example 1 is: Al in every 100ml of deionized water 2 o 3 The amount of the dispersant is 5g, the amount of the dispersant is 1.2ml, and the pH value of the nano-ceramic powder dispersion is 8.

Embodiment 3

[0016] The difference from Example 1 is: Al in every 100ml of deionized water 2 o 3 The amount of the dispersant is 15g, the amount of the dispersant is 2.4ml, and the pH value of the nano-ceramic powder dispersion is 9.

Abstract

The invention provides nano waterproof, oil-proof and antifouling finishing liquid which comprises a waterproof, oil-proof and antifouling fluorine-containing finishing agent and nano ceramic powder dispersion liquid. According to the invention, fabric has an excellent nano waterproof, oil-proof and antifouling function; after multiple times of washing, the nano waterproof, oil-proof and antifouling effect of the fabric is maintained well; moreover, the color fastness is high, and the air permeability and moisture permeability of the fabric are perfect; and after the finishing, the breaking strength of the fabric is not obviously reduced.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a nanometer waterproof, oil-proof and anti-pollution finishing liquid. Background technique [0002] Existing textiles use conventional fluorine-containing finishing agents for waterproof, oil-proof, and anti-fouling (referred to as "three-proof") finishing. Poor wetness, poor color fastness and other problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a nano-waterproof, oil-proof, and anti-fouling finishing solution, which can not only make the fabric have very good nano-waterproof, oil-proof, and anti-fouling functions, but also make the fabric three-proof after repeated washing. The effect is still very good, and the color fastness is high, the air permeability and moisture permeability of the fabric are good, and the breaking strength of the fabric does not decrease obviously after finishing. [0004] In...
