Benefits of technology

This patented technology uses different types of polymers called polypyreneimines (PPIs) for making fibres that are resistant against fire damage caused during fires. These PIPS also improve their resistance towards chemical agents like solvents. Additionally, this new material makes it easier to mix them into other materials such as fabrics made from these resins without causing any harmful side products. Overall, this technical results make better quality clothing items more effective at preventing fires while still being easy to use properly.

Problems solved by technology

This patents discusses various methods or techniques related to making flammables resistive materials like synthetic polymers called polyimides. One problem addressed in these technical solutions involves developing effective flames retarding agents without causing harmful effects upon human health due to poor solubility and stability issues associated with conventional chemical flame receptors containing heavy metals. Another issue being discussed is finding ways to achieve both long-term resistance under harsh conditions while maintaining safety standards.

Embodiment 1

[0020] S1. Preparation of Ranunculus yam extract and modification of silk fabric with the extract of Ranunculus yam:

[0021] Wash the yam tubers, peel and chop them. Weigh 150g of chopped yam tubers, add 500mL of water, grind and beat mechanically, adjust the pH value of the slurry to 8 with soda ash, heat to 85°C, soak for 80min, then stand, cool, and filter; add water to dilute the filtrate, Stir evenly and set the volume to 1L to obtain the Ranunculus yam extract. Through the above steps, the tannin condensation in the potato can be extracted, and the tannin condensation is dissolved in water.

[0022] The amount of the above-mentioned Ranunculus yam extract and silk was configured according to the bath ratio of 1:50. The silk was immersed in the extract of Ranunculus yam, and the treatment started at 30°C, and the temperature was gradually raised to 90°C at a heating rate of 2°C / min, and the temperature was kept for 70 minutes. After the soaking treatment, the silk is ...

Embodiment 2

[0027] S1. Wash, peel and chop the tubers of Ranunculus yam. Weigh 75g of chopped yam tubers, add 500mL of water, mechanically pulverize and beat, adjust the pH value of the slurry to 8 with soda ash, heat to 95°C, soak for 50min, then stand, cool, and filter; add water to dilute the filtrate, Stir evenly and set the volume to 1L to obtain the Ranunculus yam extract. The amount of the above-mentioned Ranunculus yam extract and silk was configured according to the bath ratio of 1:50. The silk was immersed in the extract of Ranunculus yam, and the treatment started at 30°C, and the temperature was gradually raised to 75°C at a heating rate of 2°C / min, and the heat preservation treatment was carried out for 120 minutes. After the soaking treatment, the silk is taken out and washed with water to obtain the silk fabric modified by the yam extract.

[0028] S2. Prepare a solution of second-generation polypropyleneimine dendrimers (molecular weight: 777 g / mol) at a concentration of...

Embodiment 3

[0030] S1. Wash, peel and chop the tubers of Ranunculus yam. Weigh 125g of chopped yam tubers, add 500mL of water, mechanically pulverize and beat, adjust the pH value of the slurry to 8 with soda ash, heat to 90°C, soak for 65min, then stand, cool, and filter; add water to the filtrate to dilute , stir evenly, and set the volume to 1L to obtain the Ranunculus yam extract. Prepare the silk and polypropyleneimine dendrimers solution at a liquor ratio of 1:50. Immerse the silk in the extract of Ranunculus yam, start treatment at 30°C, gradually raise the temperature to 85°C at a heating rate of 2°C / min, and keep it warm for 90 minutes. After the soaking treatment, the silk is taken out and washed with water to obtain the silk fabric modified by the yam extract.

[0031] S2. Prepare a 15 g / L solution of second-generation polypropyleneimine dendrimers (molecular weight: 777 g / mol), and adjust the pH of the solution to 8.5 with acetic acid and soda ash to obtain a solution of pol...

Abstract

The invention discloses a method for preparing an anti-flaming silk. The method comprises the following steps: preparing dioscorea cirhosa extract; utilizing a dipping adsorption method to absorb thecondensed tannin in the dioscorea cirhosa extract to a silk fabric, thereby acquiring a dioscorea cirhosa extract modified silk fabric; utilizing the dipping adsorption method to absorb a polypropylene imine dendrimer to the dioscorea cirhosa extract modified silk fabric under a weak alkaline condition, thereby acquiring the anti-flaming silk. According to the invention, the cross-linking reactionof the condensed tannin in the dioscorea cirhosa extract and the polypropylene imine dendrimer on the silk fabric under the weak alkaline condition is utilized to effectively promote the flame resistance of the silk fabric. The silk fabric finished according to the method provided by the invention has a durable anti-flaming function.
