Example Embodiment

[0015] Example 1

[0016] A preparation method of flame-retardant cotton fabric, the process is as follows:

[0017] (1) Add 0.5 mol of natural phytic acid compounds and 2 mol of γ-glycidoxytrimethoxysilane to 100 ml of acetone, and keep stirring and reacting at 70°C for 1 hour to obtain a flame retardant finishing solution. The flame retardant finishing solution contains phytic acid derivatives with 4 active groups, and the structural formula is:

[0018]

[0019] (2) The cotton fabric is immersed in the above flame-retardant finishing solution for 10 minutes, followed by two immersion and two rolling, with a crease rate of 90%, and then the cotton fabric is dried at 80°C for 5 minutes, and then baked at 170°C for 3 minutes, and finally the fabric is washed, Soaping and drying.

Example Embodiment

[0020] Example 2

[0021] A preparation method of flame-retardant cotton fabric, the process is as follows:

[0022] (1) Add 1 mol of natural phytic acid compounds and 3 mol of γ-glycidoxytrimethoxysilane to 80ml of isopropanol, and continue to stir and react at 80°C for 0.5h to obtain a flame retardant finishing solution. The flame retardant finishing solution contains 3 active groups of phytic acid derivatives, the structural formula is:

[0023]

[0024] (2) The cotton fabric is immersed in the above flame-retardant finishing solution for 10 minutes and then double-dipped and double-rolled with a crease rate of 80%. Then the cotton fabric is dried at 70°C for 6 minutes, and then baked at 160°C for 4 minutes, and finally the fabric is washed with water, Soaping and drying.

Example Embodiment

[0025] Example 3

[0026] A preparation method of flame-retardant cotton fabric, the process is as follows:

[0027] (1) Add 1 mol of natural phytic acid compounds and 5 mol of γ-glycidoxytrimethoxysilane to 150 ml of methanol, and continue to stir and react at 60°C for 2 hours to obtain a flame retardant finishing solution. The finishing solution contains 5 active groups of phytic acid derivatives, the structural formula is:

[0028]

[0029] (2) Immerse the cotton fabric in the above flame-retardant finishing solution for 10 minutes and then double-dip and double-roll with a crease rate of 100%. Then dry the cotton fabric at 60°C for 10 minutes, then bake at 180°C for 1.5 minutes, and finally wash the fabric with water , Soaping and drying.

Abstract

The invention discloses a preparation method of a flame-retardant cotton fabric. The preparation method comprises the following steps: adding natural phytic acid compounds and gamma-epoxy propoxy trimethoxy silane into an organic solvent, stirring and reacting for 0.5-2 hours at 50-80 DEG C to obtain a flame-retardant finishing liquid, soaking a cotton fabric into the flame-retardant finishing liquid for 8-15 minutes, then soaking and rolling twice, then drying the cotton fabric at 60-90 DEG C, baking the cotton fabric for 2-8 minutes at 150-180 DEG C, and finally performing water washing, soaping and drying. The preparation method disclosed by the invention adopts natural phytic acid as a reaction raw material, a prepared flame-retardant textile cannot release free formaldehyde, the problem of formaldehyde release of most of current flame retardants can be solved, gamma-epoxy propoxy trimethoxy silane is introduced into flame retardant molecules, the prepared flame retardants contain a plurality of reactive groups, and the problem of flame-retardant finishing durability of the cotton fabric can be solved. The technical scheme disclosed by the invention is simple in process and convenient to operate, and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, and relates to a flame retardant finishing method using natural phytic acid derivatives as raw materials as flame retardants for cotton fabrics. The phytic acid used in the method is a natural phytic acid extracted from plant seeds. Phosphorus compounds, in particular, can realize the safety and environmental protection of flame-retardant finished fabrics. The prepared flame retardant has multiple reactive groups, which can endow the fabric with better flame-retardant durability. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, the demand for flame-retardant textile fabrics is increasing. Among the flame-retardant finishing agents for cotton fabrics, tetramethylol-based flame retardants (THPC or THPOH) and N-methylol- 3-Dimethoxyphosphorylpropionamide flame retardants (trade name Pyrovatex CP) are currently...
