Embodiment 1
[0018] A manufacturing method of waterproof fabric includes the following steps:
[0019] (1). Treat the dyed and dried cotton cloth in a constant temperature and humidity box at 20°C and 70RH for 3 hours, then perform corona treatment, and treat it under 6kV for 7 seconds;
[0020] (2) After the corona treated textile is immersed with amino silicone waterproofing agent for 2s, it is double-dipped and double-rolled, with a surplus rate of 60%, and dried at 100°C for 4 minutes to obtain a soft and waterproof textile.
[0021] The preparation method of the amino organosilicon waterproof treatment agent is:
[0022] a. 0.3mol of octamethylcyclotetrasiloxane and 1mol of tetravinyltetramethoxycyclotetrasiloxane are distilled under reduced pressure under the condition of 0.75MPa to remove low boiling substances, and then 1mol of N-β is added -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and 0.001mol potassium hydroxide, reacted at 130℃ for 10h under normal pressure, then heated to 160℃, ...
Embodiment 2
[0025] A manufacturing method of waterproof fabric includes the following steps:
[0026] (1) Treat the dyed and dried polyester in a constant temperature and humidity box at 25°C and 60RH for 4 hours, and then perform corona treatment and treat it under 9kV for 3 seconds;
[0027] (2) After the corona treated textile is immersed with amino silicone waterproofing agent for 3 seconds, it is double-dipped and double-rolled, with a surplus rate of 65%, and dried at 120°C for 2 minutes to obtain a soft and waterproof textile.
[0028] The preparation method of the amino organosilicon waterproof treatment agent is:
[0029] a. 0.3mol of octamethylcyclotetrasiloxane and 1mol of tetravinyltetramethoxycyclotetrasiloxane were distilled under reduced pressure under the condition of 0.75MPa to remove low boiling substances, and then 2molN-β was added -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and 0.003mol potassium hydroxide, reacted at 150℃ for 7h under normal pressure, then heated to 160...
Embodiment 3
[0032] A manufacturing method of waterproof fabric includes the following steps:
[0033] (1) Treat the dyed and dried nylon in a constant temperature and humidity box at 28°C and 60RH for 4 hours, then perform corona treatment, and treat it under 10kV for 4 seconds;
[0034] (2) After the corona treated textile is immersed in amino silicone waterproofing agent for 5 seconds, it is double-dipped and double-rolled, with a surplus rate of 70%, and dried at 130°C for 1 minute to obtain a soft and waterproof textile.
[0035] The preparation method of the amino organosilicon waterproof treatment agent is:
[0036] a. 0.3mol of octamethylcyclotetrasiloxane and 1mol of tetravinyltetramethoxycyclotetrasiloxane are distilled under reduced pressure at a pressure of 0.75MPa to remove low-boiling substances, and then 3molN-β -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and 0.003mol potassium hydroxide, reacted at 140℃ for 8h under normal pressure, then heated to 160℃, maintained at 0.75MPa a...
