Embodiment 1

[0035] The finishing method of durable flame-retardant silk crepe chine comprises the following steps:

[0036] (1) Preparation of flame retardant finishing solution: wash, peel and chop the tubers of Ranunculus yam. Weigh 150g of chopped Rhizoma tuber, add 500mL of water, mechanically pulverize and beat, heat to 60°C, soak for 2 hours, then let stand, cool, and filter; add 30g of citric acid, 4g of sodium citrate, 6g of Dilute sodium formate with water, stir evenly, adjust the pH value to 3 with dilute sodium hydroxide and dilute hydrochloric acid, and set the volume to 1L to obtain the flame retardant finishing solution.

[0037] (2) Flame-retardant finishing method: Prepare the above-mentioned flame-retardant finishing solution and silk crepe chine at a bath ratio of 1:40. Immerse the silk crepe chine in the flame-retardant finishing solution, start the treatment at 25°C, gradually raise the temperature to 80°C at a heating rate of 2°C / min, and keep it warm for 100 minutes...

Embodiment 2

[0041]The finishing method of durable flame-retardant silk electric spinning comprises the following steps:

[0042] (1) Preparation of flame retardant finishing solution: wash, peel and chop the tubers of Ranunculus yam. Weigh 30g of chopped yam tubers, add 500mL of water, mechanically pulverize and beat, heat to 60°C, soak for 2 hours, then let stand, cool, and filter; add 15g of citric acid, 10g of sodium citrate, 6g of Dilute sodium formate with water, stir evenly, adjust the pH value to 5 with dilute sodium hydroxide and dilute hydrochloric acid, and set the volume to 1L to obtain the flame retardant finishing solution.

[0043] (2) Flame-retardant finishing method: Prepare the above-mentioned flame-retardant finishing solution and silk crepe chine at a bath ratio of 1:25. Immerse the silk electric spinning into the flame-retardant finishing solution, start the treatment at 25°C, gradually raise the temperature to 85°C at a heating rate of 2°C / min, and keep it warm for 7...

Embodiment 3

[0046] The finishing method of durable flame-retardant silk crepe satin comprises the following steps:

[0047] (1) Preparation of flame retardant finishing solution: wash, peel and chop the tubers of Ranunculus yam. Weigh 75g of chopped yam tubers, add 500mL of water, mechanically pulverize and beat, heat to 60°C, soak for 2 hours, then let stand, cool, and filter; add 22.5g of citric acid and 7.5g of sodium citrate to the filtrate 1. 6g sodium formate, dilute with water, stir evenly, adjust the pH value to 4 with dilute sodium hydroxide and dilute hydrochloric acid, and set the volume to 1L to obtain the flame retardant finishing solution.

[0048] (2) Flame-retardant finishing method: Prepare the above-mentioned flame-retardant finishing solution and silk crepe chine at a bath ratio of 1:10. Immerse the silk fibroin crepe satin in the flame-retardant finishing solution, start treatment at 25°C, gradually raise the temperature to 90°C at a heating rate of 2°C / min, and keep ...

Abstract

The invention relates to a flame-retardant arrangement liquid. The flame-retardant arrangement liquid is prepared from the following components in volume by mass: 30 to 150g / L of water extract of rhizoma dioscoreae, 15 to 30g / L of citric acid, 4 to 10g / L of sodium citrate, and 6g / L of sodium formate. The invention also discloses a method using the flame-retardant arrangement liquid to perform durable flame-retardant arrangement on a silk fabric. The method comprises the following steps of soaking the silk fabric into the flame-retardant arrangement liquid according to a bath ratio of 1:10 to 1:40, and soaking for 30 to 120min at the temperature of 60 to 95 DEG C; rolling water, drying, roasting at the temperature of 145 to 155 DEG C, washing by water, and drying, so as to obtain the durable flame-retardant silk fabric. The flame-retardant arrangement liquid has the advantages that because the water extract of rhizoma dioscoreae is contained, but the phosphor and nitrogen compounds of the traditional flame-retardant agent are not contained, the arranged silk fabric has good flame-retardant function; the flame-retardant effect, water washing-resistant property, and durability are better; the combustion safety and environment-friendly safety are good.

Description

technical field [0001] The invention relates to the technical field of flame-retardant finishing of textiles, in particular to a flame-retardant finishing liquid and a method for durable flame-retardant finishing of silk fabrics. Background technique [0002] Silk is deeply loved by consumers because of its soft and natural luster, unique silky feeling, good health care and comfort, and is widely used in clothing and high-end interior decoration products (such as bedding, carpets, furniture decoration products, curtains, etc.). my country is a big silk country, whose silk production accounts for about 70% of the world, and its export volume accounts for about 80% of the world's total export volume. It is of great significance to carry out flame-retardant finishing on silk products, improve its fire safety and added value, and meet the index requirements of export flame-retardant products. [0003] With the vigorous development of industry and popularization of home electri...
