Embodiment 1

[0015] Preparation of composite flame retardant:

[0016] Add 35 grams of cyclic phosphonate, 60 grams of zirconia, and 5 grams of aluminum zirconate coupling agent into water and mix to prepare an impregnation solution with a mass solid content of 40%.

[0017] Finishing of flame retardant polyester fabric:

[0018] The polyester fabric was immersed in the dipping solution containing the above-mentioned composite flame retardant at 95° C. for 30 minutes, and then the polyester fabric was kept at a constant temperature of 120° C. for 1 hour.

Embodiment 2

[0020] Preparation of composite flame retardant:

[0021] 40 grams of tetrakis hydroxymethyl phosphine chloride, 55 grams of zirconia, and 2 grams of aluminum zirconate coupling agent were added into water and mixed to prepare an impregnation solution with a mass solid content of 20%.

[0022] Finishing of flame retardant polyester fabric:

[0023] The polyester fabric was immersed in the dipping solution containing the above-mentioned composite flame retardant at 80°C for 20 minutes, and then the polyester fabric was kept at a constant temperature of 115°C for 2 hours.

Abstract

The invention discloses a fire-retardant finishing method of a terylene fabric. The method comprises the following steps: dipping the terylene fabric in a dipping liquid containing a composite fire retardant at 80-95DEG C for 5-30min; and carrying out temperature maintenance of the terylene fabric at 115-130DEG C for 0.5-2h, wherein the composite fire retardant comprises 30-45 parts by weight of an organophosphorus compound, 50-70 parts by weight of zirconium oxide, and 2-5 parts by weight of an aluminum-zirconium coupling agent. The method has a substantial fire retardation effect to the terylene fabric, so the finished terylene fabric has a good fire retardation endurance, and the color, the appearance, the hand feel and other physical and mechanical performances of the fabric are not affected.

Description

technical field [0001] The invention relates to a method for flame-retardant finishing of polyester fabrics. Background technique [0002] According to statistics, the number of fire deaths in China reaches thousands of people every year, and fires caused by textiles account for about half of them, with a direct economic loss of 500 million yuan. Among them, bedding, furniture upholstery and clothing are the main causes of fire. Especially in building and residential fires, textiles account for a larger proportion of fire spread. Textiles and clothing are in direct contact with human beings. Once they burn, they may cause partial skin burns and suffer pain. In addition, the harmful gases produced by the burning of textiles are also harmful to human life, such as carbon monoxide, carbon dioxide, hydrogen cyanide, nitrogen oxides, ammonia and aldehyde gases, etc., which will cause people to suffocate or poison and die. Therefore, the study of textile flame-retardant technol...
