Embodiment 1

[0029] 36g / m 2 The Lianbai electric spinning (electric spinning is a kind of silk fabric) is immersed in 1g / L dopamine aqueous solution, shaken at 35°C for 25 hours, the fabric is taken out, washed with water, and dried to obtain brown electric spinning. Soak the brown electric spinning in 1g / L potassium fluozirconate aqueous solution, shake it at 50°C for 5 hours, take it out, rinse it with water, and dry it to obtain a brown flame-retardant and water-repellent electric spinning.

[0030] According to the oxygen index method of GB / T5454-1997 textile combustion performance test, the oxygen index of the brown flame-retardant and water-repellent electric spinning prepared in this embodiment is 27.6%, while the oxygen index of the whitening electric spinning that has not been treated by the method of this embodiment The index was 23.2%. attached figure 1 It is the surface morphology of Lianbai electric spinning before and after treatment. figure 1 (a) It can be seen that the f...

Embodiment 2

[0032] 36g / m 2 The Lianbai electric spinning was dipped in a 1.5g / L dopamine aqueous solution, shaken at 40°C for 26 hours, the fabric was taken out, washed with water, and dried to obtain a brown electric spinning. Soak the brown electric spinning in 1.5g / L potassium fluozirconate aqueous solution, shake it at 60°C for 8 hours, take it out, rinse it with water, and dry it to obtain a brown flame-retardant and water-repellent electric spinning.

[0033] According to the oxygen index method of GB / T5454-1997 textile combustion performance test, the oxygen index of the brown flame-retardant and water-repellent electric spinning prepared in this example is 28.2%, while the oxygen index of the silk electric spinning that has not been treated by the method of this example is 23.2%. attached Figure 4 It is the surface morphology of the brown flame-retardant and water-repellent electric spinning prepared in this example before and after washing. The washing condition is 50°C for 20...

Abstract

The invention provides a colored flame-retardant and water-repellent natural silk fabric and a preparation method thereof. The method comprises the following steps of (1) immersing the natural silk fabric into a dopamine aqueous solution for subjecting the natural silk fabric to oscillation treatment, then taking out the natural silk fabric, washing the natural silk fabric with water and drying the natural silk fabric to obtain a colored natural silk fabric containing poly-dopamine; (2) immersing the colored natural silk fabric obtained in the step (1) in a fluorozirconate aqueous solution, subjecting the poly-dopamine contained in the colored natural silk fabric to react with fluorozirconate, taking out the colored natural silk fabric, flushing the colored natural silk fabric with cold water and drying the colored natural silk fabric to obtain the colored flame-retardant and water-repellent natural silk fabric. The colored flame-retardant and water-repellent natural silk fabric is prepared based on the biomass modification, and the raw materials of the colored flame-retardant and water-repellent natural silk fabric are environment-friendly and easy to obtain. Meanwhile, the colored flame-retardant and water-repellent natural silk fabric is good in flame-retardant and water-repellent effect and convenient for industrial production.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a colored flame-retardant and water-repellent silk fabric and a preparation method thereof. Background technique [0002] Silk has natural soft luster and smooth texture, giving people a luxurious and elegant feeling. In addition, it has hygroscopicity, air permeability, and health care properties, so it is widely used in indoor soft decoration materials, such as wall decoration, lampshades, curtains, etc. Such products usually require flame retardancy and easy care, and flame-retardant and water-repellent silk can meet the requirements of such products. [0003] Patent CN 200810195746.7 discloses a preparation method of water-repellent silk, which adopts graft copolymerization method to graft acrylic fluorine-containing monomers on silk fabrics, which can produce better water-repellent effect; patent CN201610079544.0 discloses A method for preparing superhydrophobic textiles, ...
