preparation example Construction

[0007] This embodiment provides a kind of preparation method of flame-retardant cloth, comprises the following steps:

[0008] (1) Preparation of flame retardant finishing solution: Weigh 203-308 parts of tetrakis hydroxymethyl phosphorus chloride, 42-90 parts of disodium ethylenediaminetetraacetic acid, 10-33 parts of chitosan, and mix ethylenediaminetetraacetic acid After disodium and chitosan are mixed and made into a mixed solution, tetrakis hydroxymethyl phosphorus chloride is added to the above mixed solution, and after stirring and mixing evenly, a flame retardant finishing solution is obtained for subsequent use;

[0009] (2) Padding flame retardant finishing liquid: Soak the cloth after conventional pretreatment in the flame retardant finishing liquid, take it out quickly, and carry out padding treatment on the soaked cloth at room temperature. During the padding treatment, the soaking time is 1~3h, the speed of rolling car is 15m / min, the pressure is 0.5~2.0Mpa;

Abstract

The invention discloses a preparation method of flame-retardant cloth, which comprises the following steps: mixing 42-90 parts of disodium ethylenediamine tetraacetate and 10-33 parts of chitosan to form a mixed solution, and adding the mixture to the mixed solution Add 203 to 308 parts of tetrakis hydroxymethyl phosphorus chloride, mix evenly, and obtain a flame-retardant finishing solution; soak the cloth in the flame-retardant finishing solution, and pad the soaked cloth at room temperature. After drying, the flame-retardant cloth is obtained after ammonia fumigation, oxidation, drying, tentering and pre-shrinking treatment. Using the method of the present invention to prepare flame-retardant cloth can form a stable flame-retardant polymer inside the fiber. At the same time, both disodium edetate and chitosan in the flame-retardant finishing liquid contain N elements. All substances can play a P-N synergistic effect with the P element in tetrakis hydroxymethyl phosphorus chloride, which is helpful to modify the fabric and further improve its flame retardant performance.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a preparation method of flame-retardant cloth. Background technique [0002] Flame-retardant cloth is a kind of cloth with flame-retardant function. It can be used in flame-retardant clothing and household textiles, such as fire-fighting clothing, electric welding protective clothing, sofas, wall decorations, automotive interiors, etc., and has a wide range of applications. Improve the fire prevention performance and ensure the safety of life and property. The technical level of synthetic flame-retardant fabrics in my country is not high, and most of them are still in the initial stage of exploration. Compared with the corresponding products in developed countries such as Japan, Europe and the United States, there is a big gap in overall quality and flame-retardant indicators, and those with good flame-retardant and overall performance Synthetic f...
