Problems solved by technology

Halogen flame retardants have a good flame retardant effect, but there is pollution in the process of use, which is harmful to the human body. With the continuous improvement of environmental protection regulations, the use of halogen flame retardants is restricted or even banned
Phosphorus-based flame retardants also have good flame-retardant effects, and the flame-retardant performance and durability of finished textiles are good, but there are problems such as the generation of formaldehyde

Embodiment 1

[0038] (1) Preparation of caramel flame retardant solution: first dissolve glucose in 100mL water to obtain a solution with a concentration of 10wt%, then use polypropyleneimine polymer to adjust the pH value of the solution to 12.0, and heat the solution to 95°C for 120min , to prepare caramel flame retardant liquid;

[0039] (2) Preparation of flame retardant wool fabric: use dilute sulfuric acid to adjust the pH value of the caramel flame retardant solution obtained in step (1) to 3.0, soak the wool fabric in the caramel flame retardant solution, raise the temperature to 98°C, keep it warm for 10 minutes, and then Squeeze excess water, dry at 80°C, and then bake at 145°C for 3 minutes to obtain a flame-retardant wool fabric.

Embodiment 2

[0044] (1) Preparation of caramel flame retardant solution: first dissolve sucrose in 100mL of water to obtain a solution with a concentration of 5wt%, then use polypropyleneimine polymer to adjust the pH value of the solution to 10.0, and heat the solution to 80°C for 90min , to prepare caramel flame retardant liquid;

[0045] (2) Preparation of flame retardant wool fabric: use dilute sulfuric acid to adjust the pH value of the caramel flame retardant solution obtained in step (1) to 4.0, immerse the wool power textile in the caramel flame retardant solution, raise the temperature to 90°C, and keep it warm for 10 minutes , and then squeezed out excess water, dried at 60°C and then baked at 140°C for 2 minutes to obtain a flame-retardant wool fabric.

Embodiment 3

[0047] (1) Preparation of caramel flame retardant solution: first dissolve sucrose in 100mL of water to obtain a solution with a concentration of 7.5wt%, then use polypropyleneimine polymer to adjust the pH value of the solution to 11.0, and heat the solution to 90°C to keep it warm 70min, prepared caramel flame retardant liquid;

Abstract

The invention relates to a preparation method of caramel inflaming retarding liquid and a method for inflaming retarding finishing of a wool fiber product. The preparation method of the caramel inflaming retarding liquid comprises the steps that after the pH value of a micromolecule sugar solution is adjusted through a poly propylene imine polymer, caramelization is carried out under the alkalinecondition, the caramel inflaming retarding liquid is prepared, and micromolecule sugar is monosaccharide or disaccharide. The method for inflaming retarding finishing of the wool fiber product comprises the steps that after the pH value of the caramel inflaming retarding liquid is adjusted to be acid, the caramel inflaming retarding liquid is used as inflaming retarding finishing liquid, the woolfiber product is finished through a dipping-roasting method, and the roasting temperature is not lower than the temperature that the poly propylene imine polymer and the wool fiber product generate achemical reaction. In the method, the raw materials monosaccharide and disaccharide are natural materials, and the prepared caramel inflaming retarding liquid is an environment-friendly inflaming retarding system. In the method, the raw materials are easy to obtain, the preparation process is simple, the prepared inflaming retarding wool fiber product has good inflaming retarding performance and washing resistance, and important inflaming retarding value is achieved.

Description

technical field [0001] The invention belongs to the technical field of textile functional finishing, and relates to a method for preparing a caramel flame-retardant liquid and a method for flame-retardant finishing wool fiber products. Background technique [0002] Fire is one of the major disasters causing great loss of life and economy. In recent years, fire incidents have occurred frequently in countries all over the world, and the situation is not optimistic. According to preliminary statistics, my country received a total of 237,000 fire reports in 2018, resulting in 1,407 deaths and 798 injuries, with direct property losses of about 3.675 billion yuan. The number of urban and rural residential fires accounted for 45.3% of the total, while the number of deaths accounted for 79.7% of the total. Among them, fires caused by burning textiles such as bedding, clothing, and home decorations accounted for a relatively large proportion. At present, textiles are widely used in...
