Embodiment 1

[0031] Embodiment 1. Comparison of different dosages of flame retardants

[0032] In this example, the applicant tested different dosages of flame retardants in the flame retardant working fluid of the present invention.

[0033] In this embodiment, the flame retardant working fluid includes the following components: a flame retardant and a crosslinking agent, and the rest is water, the concentration of the flame retardant is 300-600 g / L, and the concentration of the crosslinking agent is 80g / L. Wherein, the flame retardant is formed by mixing the flame retardant Pyrovatex HP and the cyclic phosphate flame retardant in a mass ratio of (1-4):1; the crosslinking agent is 2D resin.

[0034] In this example, the cloth sample is made of polyester-cotton card (116×46, 20 s ×16 s , blending ratio 50:50).

[0035] The flame retardant finishing is as follows: dip the cloth sample twice in the flame retardant working solution, dry it at 100°C, and bake it at 150°C for 3 minutes; the...

[0040] Embodiment 2. stacking method flame retardant finishing method

[0041] In this embodiment, the applicant tested the stacking flame retardant finishing method of the present invention.

[0042] In this embodiment, the flame retardant working solution includes the following components: a flame retardant and a crosslinking agent, and the rest is water, the concentration of the flame retardant is 600 g / L, and the concentration of the crosslinking agent is 80 g / L. Wherein, the flame retardant is formed by mixing the flame retardant Pyrovatex HP and the cyclic phosphate flame retardant in a mass ratio of 2:1; the crosslinking agent is 2D resin.

[0043] In this example, the cloth sample is made of polyester-cotton card (116×46, 20 s ×16 s , blending ratio 50:50).

[0044] The flame retardant finishing is as follows: dip the cloth sample twice in the flame retardant working solution, stack it for 16 hours, and bake it at 150°C for 4 minutes; then wash it in hot water, cold...

Embodiment 3

[0050] Example 3. Durability of flame retardant effect

[0051] In this example, the applicant tested the flame-retardant effect and durability of the polyester-cotton blended fabric after being flame-retardantly finished by the flame-retardant working fluid of the present invention.

[0052] In this embodiment, the flame retardant working fluid contains the following components: a flame retardant and a crosslinking agent, and the rest is water. The concentration of the flame retardant is 600 g / L, and the concentration of the crosslinking agent is 80 g / L. L. Wherein, the flame retardant is formed by mixing the flame retardant Pyrovatex HP and the cyclic phosphate flame retardant in a mass ratio of 2:1; the crosslinking agent is 2D resin.

[0053] In this example, the cloth sample is made of polyester-cotton card (116×46, 20 s ×16 s , blending ratio 50:50).

Abstract

Provided are a flame retardant working solution and flame retardant finishing method for pure cotton fabrics and / or cotton-polyester blend fabrics employing the flame retardant working solution. The flame retardant working solution comprises the following components: a flame retardant, a crosslinking agent, and the balance being water; the flame retardant in the flame retardant working solution has the concentration of 200-600 g / L, and the crosslinking agent has the concentration of 30-100 g / L. Cotton-polyester fabrics or pure cotton fabrics obtained by employing the flame retardant working solution and finishing method has good flame retardant effect and good washing resistance; the cotton-polyester fabrics pass through the GB / T 5455-1997 test, with the afterflaming time and smoldering time of less than 5 seconds after being washed thirty times, and a damaged length of less than 15 centimeters, reaching level B1 according to the GB / T 17591-2006 "flame retarded fabrics" standards, and can be widely used in flame retardant finishing of clothing, tents, upholstery fabrics and fabrics for transportation vehicles.

Description

technical field [0001] The invention relates to a flame-retardant finishing process of polyester-cotton blended fabrics, in particular to a flame-retardant working fluid for pure cotton fabrics and / or polyester-cotton blended fabrics and a flame-retardant finishing method using the flame-retardant working fluid. Background technique [0002] The flammability of polyester-cotton blended fabrics is greater than that of pure cotton and pure polyester fabrics, and its flame-retardant finishing technology is particularly difficult. This is because polyester and cotton fibers have different combustion properties, and blending makes the combustion process more complicated. When polyester burns, it becomes a molten state, while cotton fiber burns and carbonizes into a support, which spreads the melt on the support, increases the contact area with the air, and causes the fabric to burn more intensely, which is the so-called "candle wick effect". . In addition, the polyester melt fa...
