Embodiment 1

[0027] Weigh 1 g of ammonium polyphosphate and put it in a 100 ml small beaker, add polyethylene glycol 400 whose mass is 15% of the mass of ammonium polyphosphate, then add 25 ml of distilled water, and disperse ultrasonically for 5 minutes. Add 275ml of deionized water, weigh 0.3g of dopamine, then add ammonium polyphosphate suspension, use Tris and Tris-HCl to adjust the pH to 8.5, control the temperature of the reaction bath at 35°C, and continuously stir for 6 hours. Centrifuge and wash three times with water and three times with alcohol, store it in a reagent bottle, place it in an oven, adjust the temperature to 60°C, and dry it overnight. The obtained polydopamine microcapsules are made into a solution, the prepared microcapsules concentration is 2g / L, the buffer solution (Tris and Tris-HCl adjustment) with pH of 8.5 is put into silk whitening electric spinning, and the liquor ratio is 1 :50, shake in a water bath for 2 hours, and the temperature is 35°C. The real sil...

Embodiment 2

[0029] Weigh 1 g of ammonium polyphosphate and place it in a 100 ml small beaker, add polyethylene glycol 400 with a mass of 12% of the mass of ammonium polyphosphate, then add 25 ml of distilled water, and disperse ultrasonically for 5 minutes. Add 275ml of deionized water, weigh 0.3g of dopamine, then add ammonium polyphosphate suspension, use Tris and Tris-HCl to adjust the pH to 8.5, control the temperature of the reaction bath at 35°C, and continuously stir for 8 hours. Centrifuge, wash three times with water, wash three times with alcohol, store it in a reagent bottle, place it in an oven, adjust the temperature to 70°C, and dry it overnight. The obtained polydopamine microcapsules are made into a solution, the prepared microcapsules concentration is 4g / L, and the buffer solution (Tris and Tris-HCl adjustment) with a pH of 8.5 is put into the whitening power spinning of silk, and the bath ratio is 1 :50, shake in a water bath for 2 hours, and the temperature is 40°C. Th...

Embodiment 3

[0031] Weigh 1 g of ammonium polyphosphate and place it in a 100 ml small beaker, add polyethylene glycol 400 whose mass is 10% of the mass of ammonium polyphosphate, then add 25 ml of distilled water, and disperse ultrasonically for 10 minutes. Add 275ml of deionized water, weigh 0.75g of dopamine, then add ammonium polyphosphate suspension, use Tris and Tris-HCl to adjust the pH to 8.5, control the temperature of the reaction bath at 40°C, and continuously stir for 8 hours. Centrifuge, wash three times with water, wash three times with alcohol, store it in a reagent bottle, place it in an oven, adjust the temperature to 70°C, and dry it overnight. The obtained polydopamine microcapsules are made into a solution, the prepared microcapsules concentration is 2g / L, the buffer solution (Tris and Tris-HCl adjustment) with pH of 8.5 is put into silk whitening electric spinning, and the liquor ratio is 1 :40, shake in a water bath for 2 hours, and the temperature is 40°C.

Abstract

The invention relates to a preparation method of a black flame retardant silk broadcloth. The preparation method comprises the following steps: step one, placing ammonium polyphosphate or melamine coated ammonium polyphosphate in a beaker, adding polyethylene glycol 400, adding water into the beaker, and carrying out ultrasonic dispersion to obtain ammonium polyphosphate turbid liquid; step two, adding deionized water into the ammonium polyphosphate turbid liquid obtained in the step one, adding dopamine to adjust the pH to 8.5-9, carrying out reactions for a while under continuous stirring, carrying out centrifugation, washing the reaction product by water for three times, then washing the reaction product by alcohol for three times, storing the reaction product in a reagent bottle, placing the reagent bottle in a baking oven, and drying the reaction product for one night to obtain polydopamine microcapsules; step three, preparing a solution from the polydopamine microcapsules obtained in the step two, adopting a buffer solution with a pH of 8.5, adding silk broadcloth, wherein the bath ratio is 1:30-50, carrying out water bath under vibration, taking out the silk broadcloth, washing the silk broadcloth by water, and drying the silk broadcloth in the air to obtain the black flame retardant silk broadcloth. The invention also relates to a black flame retardant silk broadcloth obtained by the provided preparation method. The preparation method has the advantages that the silk broadcloth is enabled to have a flame retardant property, the dyeing and finishing are integrated, the color is uniform, energy is saved, and the discharge is reduced.

Description

technical field [0001] The invention relates to the technical field of textile finishing, in particular to a black flame-retardant silk and a preparation method thereof. Background technique [0002] Fires caused by textiles account for approximately 20 percent of residential fires, but account for 50 percent of deaths in fires due to fires caused by textiles. All countries have legislated to put forward corresponding flame retardant performance requirements for textiles used in different fields. [0003] Due to its comfort, health care and noble and gorgeous appearance, real silk has been widely used in decorative materials in recent years, such as wall coverings, decorative hanging pictures, carpets, etc. my country's "Fire Law" stipulates that decorative fabrics must be flame retardant. The flame retardant treatment of real silk can not only reduce its danger in fire, but also increase the added value of the product. [0004] There have been many reports on the flame-r...
