Examples
Embodiment 1
[0042] (1) Mix acrylate, penetrant NR, maleate, ammonium persulfate and water to prepare the first finishing solution, wherein the concentration of acrylate is 50g / L, and acrylate is dimethyl methacrylate A mixture of amino ethyl ester, hydroxyethyl methacrylate and methyl methacrylate, the mass ratio of the three is 1:1:1, the concentration of penetrant NR is 25g / L, and the concentration of maleate is 12g / L L, the concentration of ammonium persulfate is 8g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 65%, coiled, stacked at 50° C. for 24 hours, then washed with water and dried.
[0043] (2) Add the hydrophilic softener SYNICO-6811 into water to prepare the second finishing liquid, wherein the concentration of the hydrophilic softener SYNICO-6811 is 50 g / L. Then, it was dried at 85° C. for 2 minutes, and then baked at 150° C. for 3 minutes to obtain finished cotton fabric A1.
Embodiment 2
[0045](1) Mix acrylate, penetrant NR, fumarate, ammonium persulfate and water to prepare the first finishing solution, wherein the concentration of acrylate is 40g / L, and acrylate is dimethyl methacrylate A mixture of amino ethyl ester, hydroxyethyl methacrylate and methyl methacrylate, the mass ratio of the three is 1:0.8:1.2, the concentration of penetrant NR is 30g / L, and the concentration of fumarate is 8g / L L, the concentration of ammonium persulfate is 6g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 60%, coiled, stacked at 40° C. for 48 hours, then washed with water and dried.
[0046] (2) Add the hydrophilic softener SYNICO-6811 into water to prepare the second finishing liquid, wherein the concentration of the hydrophilic softener SYNICO-6811 is 40 g / L. Then, it was dried at 90° C. for 1 minute, and then baked at 140° C. for 5 minutes to obtain finished cotton fabric A2.
Embodiment 3
[0048] (1) Acrylate, penetrant NR, itaconate, ammonium persulfate and water are mixed to obtain the first finishing solution, wherein the concentration of acrylate is 60g / L, and acrylate is dimethyl methacrylate A mixture of amino ethyl ester, hydroxyethyl methacrylate and methyl methacrylate, the mass ratio of the three is 1:1.2:0.8, the concentration of penetrant NR is 20g / L, and the concentration of itaconate is 15g / L L, the concentration of ammonium persulfate is 10g / L. The cotton fabric was soaked twice and rubbed with the first finishing liquid, the squeeze rate was controlled to 70%, coiled, stacked at 60° C. for 12 hours, then washed with water and dried.
[0049] (2) Add the hydrophilic softener SYNICO-6811 into water to prepare the second finishing liquid, wherein the concentration of the hydrophilic softener SYNICO-6811 is 60 g / L. Then, it was dried at 75° C. for 3 minutes, and then baked at 160° C. for 1 minute to obtain finished cotton fabric A3.
