Example Embodiment
[0023] Example 1
[0024] The amount of amino methyl phosphonate (DAMP) was 150 g / L, and the amount of GPTMS was 40 g / L. The pH of the finishing solution was adjusted to 4.0 with acetic acid to prepare the flame retardant finishing solution. The cotton fabric is immersed in the above-mentioned finishing solution, and immersed at 40°C for 20 minutes, one dipping and one rolling, and the liquid rate is 75%. Then dry at 100℃ for 3min, 165℃for 3min, flame-retardant cotton fabric can be made, according to the specified flame-retardant test standard, flame-retardant performance: continuous burning time 0s, smoldering time 0s, damaged charcoal length 11.5 cm.
Example Embodiment
[0025] Example 2
[0026] The amount of amino methyl phosphonate (DAMP) was 300 g / L, and the amount of GPTMS was 40 g / L. The pH of the finishing solution was adjusted to 4.0 with acetic acid to prepare the flame retardant finishing solution. The cotton fabric is immersed in the above-mentioned finishing solution, and immersed at 40°C for 20 minutes, one dipping and one rolling, and the liquid rate is 75%. Then dry at 100℃ for 3min, 165℃for 3min, flame-retardant cotton fabric can be made, according to the specified flame-retardant test standard, flame-retardant performance: continuous burning time 0s, smoldering time 0s, damaged charcoal length 9.2 cm.
Example Embodiment
[0027] Example 3
[0028] The amount of amino methyl phosphonate (DAMP) was 300 g / L, and the amount of GPTMS was 10 g / L. The pH of the finishing solution was adjusted to 4.0 with acetic acid to prepare the flame retardant finishing solution. The cotton fabric is immersed in the above-mentioned finishing solution, and immersed at 40°C for 20 minutes, one dipping and one rolling, and the liquid rate is 75%. Then dry at 100℃ for 3min, 165℃for 3min, flame-retardant cotton fabric can be made, according to the specified flame-retardant test standard, flame-retardant performance: continuous burning time 0s, smoldering time 0s, damaged charcoal length 9.6 cm; flame retardant performance after 10 washings: continued burning time 0s, smoldering time 0s, damaged charcoal length 15.4cm.
