Embodiment 1
[0026] A post-finishing process for luminous water-repellent polyester fabrics, comprising the following steps:
[0027] Step 1. Fabric pretreatment: put the polyester fabric in a 8g / L sodium bicarbonate solution in a water bath at 80°C for 30 minutes;
[0028] Step 2. Water-repellent finishing: use 40g / L water-repellent finishing agent and 8g / L cross-linking agent to carry out water-repellent finishing on the polyester fabric by dipping and rolling. The bath ratio is 1:32, the soaking time is 10min, and the rolling ratio is 75%. %, and then dried at 90°C for 5 minutes;
[0029] Step 3, preparation of luminous coating: take 20 parts of zinc sulfide type luminous powder, 2 parts of acrylate adhesive, 6 parts of polyethylene glycol, 2 parts of soybean protein glue, 1 part of guar gum and 2 parts of sodium sulfate in parts by weight 1. Mix 2 parts of sodium hexametaphosphate and 200 parts of water, add sodium bicarbonate solution to adjust the pH of the solution to 7.0, stir at ...
Embodiment 2
[0036] A post-finishing process for luminous water-repellent polyester fabrics, comprising the following steps:
[0037] Step 1. Fabric pretreatment: put the polyester fabric in a 9g / L sodium bicarbonate solution in a water bath at 83°C for 36 minutes;
[0038] Step 2. Water-repellent finishing: Use 45g / L water-repellent finishing agent and 9g / L cross-linking agent to carry out one-dipping and one-rolling water-repellent finishing on the polyester fabric. The bath ratio is 1:31, the soaking time is 13min, and the rolling ratio is 77%. %, and then dried at 95°C for 8 minutes;
[0039] Step 3, preparation of luminous coating: take 30 parts of zinc sulfide type luminous powder, 4 parts of acrylate adhesive, 8 parts of polyethylene glycol, 4 parts of soybean protein glue, 3 parts of guar gum and 6 parts of sodium sulfate in parts by weight 1. Mix 5 parts of sodium hexametaphosphate and 100 parts of water, add sodium bicarbonate solution to adjust the pH of the solution to 7.2, st...
Embodiment 3
[0046] A post-finishing process for luminous water-repellent polyester fabrics, comprising the following steps:
[0047] Step 1. Fabric pretreatment: put the polyester fabric in a 10g / L sodium bicarbonate solution in a water bath at 95°C for 40 minutes;
[0048] Step 2. Water-repellent finishing: Use 50g / L of water-repellent finishing agent and 10g / L of cross-linking agent to carry out one-dipping and one-rolling water-repellent finishing on the polyester fabric. The liquor ratio is 1:30, the soaking time is 15min, and the rolling ratio is 80% %, and then dried at 100°C for 10 minutes;
[0049] Step 3, preparation of luminous coating: take 22 parts of zinc sulfide type luminous powder, 3 parts of acrylate adhesive, 7 parts of polyethylene glycol, 3 parts of soybean protein glue, 2 parts of guar gum and 3 parts of sodium sulfate in parts by weight 1. Mix 3 parts of sodium hexametaphosphate and 180 parts of water, add sodium bicarbonate solution to adjust the pH of the solution...
