Embodiment 1
[0025] (1) The fabric is pad-rolled with a pretreatment solution containing 1% sodium silicate, 0.5% Triton X-100, 0.3% ammonium citrate, and water in the mass fraction by two-dipping and two-rolling process, and pre-treated at 60°C. Bake for 3 minutes, steam and dry for 6 minutes at 120° C. to obtain a pretreated fabric, wherein the squeeze rate is controlled at 70%;
[0026] (2) Pass the pretreated fabric in step (1) through the two-dipping and two-rolling process. The mixed solution was pre-baked at 80°C and baked at 130°C for 1min, wherein the squeeze-out rate was controlled at 75%;
[0027] (3) Gradually add 0.05mol of bismuth nitrate, 0.005mol of disodium edetate and 0.005mol of polyethylene glycol into 200mL of phosphate buffer under stirring at 500r / min, and then add the treated Add 200mL of phosphate buffer solution containing 0.05mol ammonium metavanitate dropwise to 5g of the fabric. After the dropwise addition, adjust the pH value of the reaction system to 5 with ...
Embodiment 2
[0032] (1) The fabric is pad-rolled with a pretreatment solution containing 6% sodium silicate, 4% Triton X-100, 7% ammonium sulfate, and water in the mass fraction by two-dipping and two-rolling process, and pre-dried at 60°C 4min, steam drying at 140°C for 11min to obtain a pretreated fabric, wherein the squeeze rate is controlled at 75%;
[0033] (2) The fabric pretreated in step (1) is pad-rolled by two-dipping and two-rolling process in a mixture containing 11% dimethylol phosphoric acid, 12% urea, 10% aluminum hydroxide, and the balance is water. The mixed solution was pre-baked at 90°C, and then baked at 150°C for 2 minutes, wherein the squeeze rate was controlled at 80%;
[0034] (3) Gradually add 0.1mol bismuth chloride, 0.025mol tetrasodium edetate and 0.075mol polyethylene glycol to 200mL phosphate buffer solution under stirring at 1000r / min, and then add to step (2) for treatment After adding 10g of fabric, add 200mL of phosphate buffer containing 0.01mol potassiu...
Embodiment 3
[0038] (1) The fabric is pad-rolled with a pretreatment solution containing 15% sodium silicate, 8% Triton X-100, 12% ammonium chloride, and water in the mass fraction by two-dipping and two-rolling process, and pre-treated at 85°C. Dried for 5 minutes, steamed and dried for 15 minutes at 160° C. to obtain a pretreated fabric, wherein the squeeze rate was controlled at 80%,
[0039] (2) The fabric pretreated in step (1) is pad-rolled by two-dipping and two-rolling process in a mixture containing 20% dimethylol phosphoric acid, 20% urea, 13% aluminum hydroxide, and the balance is water. The mixed solution was pre-baked at 95°C and baked at 160°C for 3 minutes, wherein the squeeze-out rate was controlled at 785%;
[0040] (3) Gradually add 0.15mol bismuth acetate, 0.05mol sodium gluconate and 0.01mol polyethylene glycol to 200mL phosphate buffer under stirring at 1500r / min, and then add 15g of the fabric treated in step (2), Then add 200 mL of phosphate buffer solution contai...
