Chinese invention patent CN103696267A discloses a novel flame retardant finishing method for polyester fabrics, which uses ammonium polyphosphate as a flame retardant and polytetrafluoroethylene as an anti-melt dripping agent, but ammonium polyphosphate and polyester fibers are combined by van der Waals force, and the washing resistance is improved. Poor, and the finishing process is complicated, which makes the feel of polyester fabrics worse
Chinese invention patent CN 108797112A discloses a durable flame-retardant textile, which uses the similar compatibility of cyclic phosphates to produce a durable flame-retardant polyester fabric. The flame-retardant polyester fabric has a good feel, but the smoke release is extremely large, which is a fire hazard. more sexual

Embodiment 1

[0029] A durable flame-retardant low-smoke recycled polyester fabric and a preparation method thereof, the specific steps are as follows:

[0030] (1) Preparation of nano-magnesium hydroxide: Add 0.1g Tween 80 into 200mL (1.5mol / L) magnesium chloride solution, completely dissolve and evenly disperse in the solution, place it in the dropping funnel A; take 200mL ( 1.5mol / L) sodium hydroxide solution was placed in the dropping funnel B; the above-mentioned magnesium chloride solution and sodium hydroxide solution were added dropwise to 50mL (0.75mol / L) sodium chloride lining at a rate of 3.3mL / min. In the bottom solution, while maintaining the speed of 1200r / min, the temperature of the water bath is 60°C. After the reaction is complete, it is centrifuged and washed until no chlorine ions are detected, and then vacuum-dried at 60°C for 6 hours to obtain white nano-magnesium hydroxide.

Abstract

The invention relates to a durable flame-retardant low-smoke polyester fabric and a preparation method thereof, belonging to the technical field of textile finishing. The present invention adopts post-finishing method to process and arrange the surface of polyester fabric, and by means of high-temperature and high-pressure impregnation method, the polyester fiber is expanded, the surface pores are increased, the specific surface area is increased, the molecular movement is intensified, and the cyclic phosphate ester and inorganic nano-particle flame retardant At the same time, it enters the interior of the polyester fabric, and after returning to normal temperature, the flame retardant can be firmly wrapped inside the polyester fabric, making the flame-retardant polyester durable and flame-retardant and smoke-suppressive. In the preparation method of the invention, the flame retardant and smoke suppression can be completed in one step, the production steps are reduced, the flame retardant and smoke suppression effects are good, and at the same time, it has durability and is convenient for industrialized production.

Description

technical field [0001] The invention relates to the technical field of textile finishing, in particular to a durable flame-retardant low-smoke polyester fabric and a preparation method thereof. Background technique [0002] Due to its symmetrical benzene ring macromolecule and rigid conjugated structure, polyester fabric has high strength, high modulus and excellent chemical stability, making it widely used in clothing, industry and decoration. The demand for polyester has grown rapidly over the past few decades. Among them, polyester has poor flame retardancy and is easy to melt due to its high crystallinity. The need for flame-retardant polyester is imminent. There are no reactive groups on the surface of polyester fabrics, which makes it deviate in the fastness of general flame-retardant finishing. Therefore, finding a simple and effective flame retardant has always been the goal of human beings. In the last century, a cyclic phosphate polyester flame retardant was suc...
