Problems solved by technology

However, since polyester itself does not have flame retardant properties, it will burn rapidly and form drips under open flame conditions, causing secondary fire sources, easily causing scalds, burns, etc., and burning will release a large amount of smoke causing suffocation. Security risks

Embodiment 1

[0021] The sample size is 1.5cm wide and 15cm long PET warp-knitted short fleece fabric. The reason why the short fleece fabric is selected is that the fleece fabric has a larger specific surface area and is more flammable than other fabrics. The experimental data of the relationship between ATP concentration, burning time and burning times are shown in the table below:

[0022] Table 1 ATP concentration and burning time and burning times

[0023]

[0024] The number of burning times in the table is the number of times the fabric after flame-retardant finishing is automatically extinguished during the burning process, indicating that the PET fabric after ATP finishing has the characteristics of self-extinguishing. time.

Embodiment 2

[0026] The relationship between glycerol concentration and burning times and time is shown in the table below:

[0027] Table 2 Glycerol concentration and burning time and burning times

[0028]

[0029] It can be seen from the table that when the auxiliary agent glycerin is added to 150ml / L, the flame retardant effect is the best. During the combustion test, the number of self-extinguishing times reached 8 times, and the burning time reached 93.29 seconds.

Embodiment 3

[0031] The experimental data of the relationship between immersion time, burning time and burning times are shown in the table below

[0032] Table 3 Immersion time and burning time and burning times

[0033]

[0034] From the data in Table 3, draw a line chart of the relationship between the immersion time, the burning time and the number of burning times, and it can be concluded that the best process should choose the immersion time to be 50 minutes.

Abstract

The invention discloses a preparation method and an application of an efficient flame retardation after-finishing agent. The preparation method of the after-finishing agent comprises the following steps: 1, adding a flame retardant ATP (aluminum triphosphate) to distilled water to prepare a solution A, and fully stirring for dissolving, wherein the mass-volume fraction of the flame retardant ATP in the solution A is 10-200g / L, and the volume of the distilled water is 5-10%; 2, dissolving 0.0005-0.0015g of NaOH in 10ml of distilled water to obtain a solution B, adding the solution B to the solution A in a dropwise manner, and adjusting the pH value of the solution A to 6-6.5 to obtain a solution C; 3, adding 50ml of distilled water to the solution C to obtain a solution D; and 4, adding 50-200ml / L of glycerol and 5-50g / L of tannic acid to the solution D, stirring, and diluting by using water to a prescribed scale of 100ml in order to obtain the after-finishing agent. The formula of an efficient and green flame retardant and a fabric after-finishing technology are researched in the invention, so the obtained flame retardation after-finishing agent has an efficient flame retardation function, and can be applied in flame retardation after-finishing of polyester fabrics to meet people's needs of fireproof safety functions.

Description

technical field [0001] The invention designs a finishing agent formula, specifically a preparation method of a high-efficiency flame-retardant finishing agent and its application on flame-retardant fabrics. It belongs to the technical field of functional textile materials. Background technique [0002] Polyester fiber fabric (polyesterfibre) is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. The polyester chain research report pointed out that the industrialized mass-produced polyester fiber is made of polyethylene terephthalate, and the trade name in China is polyester. It is the largest variety of synthetic fibers at present. [0003] Polyester is the world's largest and most widely used synthetic fiber variety, and polyester accounts for more than 60% of the world's synthetic fiber production. Polyester is widely used in textiles, garments, home textiles and other fields, and is the fabric with ...
