Embodiment 1
[0026] The long-lasting anti-felting finishing method for wool fabrics comprises the following steps:
[0027] 1) The wool fabric is placed in a plasma treatment apparatus for plasma pretreatment to obtain wool fabric a; wherein the plasma treatment conditions are: vacuum degree 35Pa, discharge time 3min, discharge power 50W;
[0028]2) Add tetrabutyl titanate to absolute ethanol and stir to prepare a tetrabutyl titanate solution with a concentration of 4%, and set aside; mix deionized water and absolute ethanol at a volume ratio of 1:3, and then add dropwise Adjust the pH to 3 with acetic acid to obtain a mixed solution for later use; put the wool fabric a into the tetrabutyl titanate solution at a bath ratio of 1:30, and then use the volume ratio of the mixed solution to the tetrabutyl titanate solution at a ratio of 1:2 , adding the mixed solution dropwise into the tetrabutyl titanate solution, standing still for 5 hours, placing the woolen fabric in an oven at 50° C. for 2...
Embodiment 2
[0034] The long-lasting anti-felting finishing method for wool fabrics comprises the following steps:
[0035] 1) The wool fabric is placed in a plasma treatment apparatus for plasma pretreatment to obtain wool fabric a; wherein the plasma treatment conditions are: vacuum degree 20Pa, discharge time 1min, discharge power 100W;
[0036] 2) Add tetrabutyl titanate to absolute ethanol and stir to prepare a tetrabutyl titanate solution with a concentration of 2%, and set aside; mix deionized water and absolute ethanol at a volume ratio of 1:3, and then add dropwise Adjust the pH to 2 with acetic acid to obtain a mixed solution for later use; put the wool fabric a into the tetrabutyl titanate solution at a bath ratio of 1:30, and then use the ratio of the mixed solution to the tetrabutyl titanate solution at a volume ratio of 1:2 , adding the mixed solution dropwise into the tetrabutyl titanate solution, standing still for 4 hours, placing the woolen fabric in an oven at 50° C. for...
Embodiment 3
[0042] The long-lasting anti-felting finishing method for wool fabrics comprises the following steps:
[0043] 1) The wool fabric is placed in a plasma treatment apparatus for plasma pretreatment to obtain wool fabric a; wherein the plasma treatment conditions are: vacuum degree 30Pa, discharge time 2min, discharge power 80W;
[0044] 2) Add tetrabutyl titanate to absolute ethanol and stir to prepare a tetrabutyl titanate solution with a concentration of 5%, and set aside; mix deionized water and absolute ethanol at a volume ratio of 1:3, and then add dropwise Adjust the pH to 2.5 with acetic acid to obtain a mixed solution for later use; put the wool fabric a into the tetrabutyl titanate solution at a bath ratio of 1:30, and then use the ratio of the mixed solution to the tetrabutyl titanate solution at a volume ratio of 1:2 , adding the mixed solution dropwise into the tetrabutyl titanate solution, standing still for 6 hours, placing the woolen fabric in an oven at 50° C. fo...
