Embodiment 1

[0042] In the present embodiment, the selected fabric is cotton / nylon 6 blended fabric, and the fabric weight per square meter is 232g / m 2 . The content of nylon 66 in the blended fabric is 50%, and the content of cotton is 50%.

[0043] The specific arrangement method is as follows:

[0044](1) The first bath finishing liquid is: 30 g / L of oxidized polyethylene wax emulsion, 20 g / L of hydrophilic polysiloxane emulsion, and 50 g / L of sodium m-nitro-p-toluenesulfonate. The first-bath finishing solution was applied to the above-mentioned blended fabric by padding, and then dried at 60°C.

[0045] (2) The second bath finishing solution is: 350g / L of tetrahydroxymethylphosphonium salt and urea initial shrinkage body (THPS-U), flame retardant DM-307080g / L, cyclic phosphate ester 50g / L, carbamoyl Hydrazine 30g / L, urea 40g / L, etherified 2D resin 20g / L. The second-bath finishing solution was applied to the blended fabric after the first-bath finishing by padding, and then dried at...

Embodiment 2

[0053] In the present embodiment, the selected fabric is cotton / nylon 66 blended fabric, and the fabric weight per square meter is 305g / m 2 . In this blended fabric, the content of nylon 66 is 60%, and the content of cotton is 40%.

[0054] The specific arrangement method is as follows:

[0055] (1) The first bath finishing solution is: bis(oleyl carboxyethyl) hydroxyethyl methyl sulfate ammonium salt 20g / L, hydrophilic polysiloxane emulsion 30g / L, m-nitro-p-toluenesulfonic acid Sodium 30g / L, sodium m-nitrobenzenesulfonate 30g / L. The first-bath finishing solution was applied to the above-mentioned blended fabric by padding, and then dried at 60°C.

[0056] (2) The second bath finishing solution is: tetrakis hydroxymethyl phosphonium salt and urea initial contraction body (THPC-U) 400g / L, flame retardant DM-307080g / L, N-hydroxymethyl-3-(dimethyl Oxyphosphono) propionamide 50g / L, cyclic phosphate ester 60g / L, N-methylolacrylamide 20g / L, urea 50g / L, etherified 2D resin 10g / L,...

Abstract

The invention provides a flame-retardant finishing method for cotton / nylon blended fabric. According to the flame-retardant finishing method, through a three-bath finishing method, cotton / nylon blended fabric finished by the method has good fireproof performance, durability and comfortable hand feeling and has no peculiar smell.

Description

technical field [0001] The invention relates to a textile finishing process, in particular to a flame-retardant finishing method for cotton / nylon blended fabrics. Background technique [0002] Cotton / nylon blended fabric has the characteristics of softness, wear resistance and good elasticity. It is an ideal fabric for making various men's and women's clothing, especially military clothing. And endowing cotton / nylon blends with durable fire protection can make them more functional and have a wider range of applications. [0003] Nylon fiber is a thermoplastic fiber, which will soften when heated and burn, and then melt and shrink to form melted droplets. Cotton fiber is a non-thermoplastic fiber and will be carbonized after burning. The situation is completely different when cotton / nylon blend fabrics burn when exposed to heat. The heated and melted nylon component will cover the surface of the cotton fiber, and the cotton fiber will be carbonized to form a skeleton, whic...
