Embodiment 1

[0012] A method for flame-retardant finishing of polyester fabrics, comprising the steps of:

[0013] 1) Mix 2 parts of hydroxypropyl methylcellulose, 9 parts of aluminum zirconate coupling agent, and 15 parts of tetrakishydroxymethyl phosphine chloride, and then slowly add 20 parts of cyclic phosphonate and 35 parts of zirconia at the same time, The feeding is completed within 20 minutes, and the mixing is continued for 25 minutes to obtain a composite flame retardant;

[0014] 2) Soak the polyester fabric in the dipping solution containing 60% composite flame retardant at 65°C for 2 hours;

[0015] 3) Keep the polyester fabric at 150°C for 4 hours after taking it out.

Embodiment 2

[0017] A method for flame-retardant finishing of polyester fabrics, comprising the steps of:

[0018] 1) Mix 1 part of hydroxypropyl methylcellulose, 8 parts of aluminum zirconate coupling agent, and 10 parts of tetrakishydroxymethylphosphine chloride, and then slowly add 15 parts of cyclic phosphonate and 30 parts of zirconia at the same time, The feeding is completed within 15 minutes, and the mixing is continued for 20 minutes to obtain a composite flame retardant;

[0019] 2) Soak the polyester fabric in the dipping solution containing 55% composite flame retardant at 60°C for 1 hour;

[0020] 3) Keep the polyester fabric at 145°C for 3 hours after taking it out.

Embodiment 3

[0022] A method for flame-retardant finishing of polyester fabrics, comprising the steps of:

[0023] 1) Mix 1.2 parts of hydroxypropyl methylcellulose, 8.9 parts of aluminum zirconate coupling agent, and 13 parts of tetrakishydroxymethyl phosphine chloride, and then slowly add 16 parts of cyclic phosphonate and 34 parts of zirconia at the same time, The feeding is completed within 17 minutes, and the mixing is continued for 23 minutes to obtain a composite flame retardant;

[0024] 2) Soak the polyester fabric in the dipping solution containing 57% composite flame retardant at 63°C for 1.5 hours;

[0025] 3) Keep the polyester fabric at 147°C for 3.5 hours after taking it out.

Abstract

The invention discloses a flame-retardant finishing method for a polyester fabric. The method comprises the following steps: (1) mixing 1-2 parts of hydroxypropyl methyl cellulose, 8-9 parts of an aluminum zirconium coupling agent and 10-15 parts of tetrahydroxymethyl phosphonium chloride, simultaneously slowly adding 15-20 parts of cyclic phosphonate and 30-35 parts of zirconia, finishing batching within 15-20 minutes, and continuously mixing for 20-25 minutes to prepare a composite flame retardant; (2) impregnating the polyester fabrics in an impregnation solution containing 55-60 percent of composite flame retardant at the temperature of 60-65 DEG C for 1-2 hours; and (3) taking out the polyester fabric, and keeping the temperature of the polyester fabric to be 145-150 DEG C for 3-4 hours. The polyester fabric has high flame-retardant durability comprising washing resistance, resistance to dry cleaning and weather resistance, and color, appearance, handfeel and other physical and mechanical properties of the polyester fabric are not influenced.

Description

technical field [0001] The invention relates to a method for flame-retardant finishing of polyester fabrics. Background technique [0002] At present, the flame retardant finishing method of polyester fabric usually uses bromine and antimony compounds as flame retardants, but the above flame retardants have been banned in the European Union. Therefore, it is urgent to develop flame-retardant polyester fabrics with low toxicity or even non-toxicity and lasting flame-retardant effect. Contents of the invention [0003] The object of the present invention is to provide a method for flame-retardant finishing of polyester fabric, so that the polyester fabric has good flame-retardant durability. [0004] In order to achieve the above object, the technical solution of the present invention is to design a method for flame-retardant finishing of polyester fabrics, comprising the following steps: [0005] 1) Mix 1-2 parts of hydroxypropyl methylcellulose, 8-9 parts of aluminum zir...
