Problems solved by technology

The flame retardant effect of traditional polyester fabric is not good, and it is easy to produce harmful carcinogens during the combustion process, causing environmental pollution, and it is easy to produce molten drops at high temperatures. These high temperature drops are likely to cause secondary damage to the human body or the surrounding environment. secondary injury

Embodiment 1

[0013] (1) Add carbon tetrachloride, phosphorus trichloride and pentaerythritol into the four-necked flask in turn and stir, add bromine water dropwise to the four-necked flask at a low temperature of 15°C, and discharge the generated hydrogen chloride gas at the same time, and react 5 hours, aftertreatment obtains chlorinated bisphosphate flame retardant;

[0014] (2) The solid chlorinated bisphosphate flame retardant is sprayed on the polyester fabric by a vacuum magnetron sputtering instrument, the vacuum magnetron sputtering instrument is filled with argon, and the spray lasts for 20 minutes, and the polyester fabric is sprayed. Dry at low temperature to obtain flame-retardant polyester fabric.

Embodiment 2

[0016] (1) Add carbon tetrachloride, phosphorus trichloride and pentaerythritol into the four-necked flask in sequence and stir, add bromine water dropwise into the four-necked flask at a low temperature of 17°C, and discharge the generated hydrogen chloride gas at the same time, and react 3 hours, aftertreatment obtains chlorinated bisphosphate flame retardant;

[0017] (2) Spray the solid chlorinated bisphosphate flame retardant on the polyester fabric through a vacuum magnetron sputtering instrument, the vacuum magnetron sputtering instrument is filled with argon, and the spraying lasts for 29 minutes, and the polyester fabric is sprayed. Dry at low temperature to obtain flame-retardant polyester fabric.

Embodiment 3

[0019] (1) Add carbon tetrachloride, phosphorus trichloride and pentaerythritol into the four-necked flask in sequence and stir, add bromine water dropwise into the four-necked flask at a low temperature of 20°C, and discharge the generated hydrogen chloride gas at the same time, and react 4 hours, aftertreatment obtains chlorinated bisphosphate flame retardant;

Abstract

The invention discloses a production method of flame-retardant polyester fabric. The production method comprises the following steps: adding carbon tetrachloride, phosphorus trichloride and pentaerythritol in a four-hole boiling flask in sequence and stirring, dripping bromine water in the four-hole boiling flask at a low temperature, meanwhile, exhausting the generated hydrogen chloride gas, reacting for a certain time, and postprocessing to obtain a chloro-biphosphonate flame retardant; jetting the solid chloro-biphosphonate flame retardant on the polyester fabric for 20 to 30 minutes through a vacuum magnetron sputtering instrument, and drying the polyester fabric at a low temperature to obtain the flame-retardant polyester fabric. Through the manner, the production method of the flame-retardant polyester fabric, which is provided by the invention, is simple to operate, has a low requirement on the operation proficiency of personnel and saves the labor cost; and the flame-retardant polyester fabric takes a self-extinguishing effect, is green and environment-friendly, and less in environmental pollution, does not generate melted drippings at a high temperature but is charred, and does not cause secondary damage.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for producing flame-retardant polyester fabrics. Background technique [0002] Today, with the rapid development of science and technology and the continuous improvement of people's living standards, fire is still an unavoidable accident in production and life. In recent years, fires and the casualties caused by them are also on the rise in my country. At present, most of the textile fabrics used are flammable or combustible materials, and they are also the initial fires that cause fires. The economic losses and casualties caused by fires are countless every year. Flame retardant fabrics are needed in fields such as The flame retardant effect of traditional polyester fabric is not good, and it is easy to produce harmful carcinogens during the combustion process, causing environmental pollution, and it is easy to produce molten drops at high temperatures. These high temper...
