Embodiment 1

[0033] Take tetrakis hydroxymethyl phosphorus sulfate (THPS) (300g / L), cotton flame retardant DM-3070 (100g / L), acrylamide (60g / L), silicone oil WS-3 (40g / L), 750 mesh hydrogen Magnesium oxide I (40g / L) and 9500-mesh magnesium hydroxide II (20g / L) were used to prepare a flame-retardant working solution, and then polyester-cotton yarn card (116×46, 20s×16s, blending ratio 50:50) was dipped twice Roll the flame retardant working solution (the liquid rolling rate is about 60%), dry at 100°C, bake (150°C×3min), and then use 25% hydrogen peroxide (20g / L) and catalyst DM-1435 (2g / L) After treatment, sodium bisulfite (40g / L) was used to capture formaldehyde on the cloth surface, followed by hot water washing and cold water washing to obtain a durable flame-retardant polyester-cotton fabric.

Embodiment 2

[0035] Take tetrahydroxymethyl phosphorus chloride (THPC) (200g / L), N-hydroxymethyl-3-(dimethoxyphosphono) propionamide (PyrovatexCP) (100g / L), cotton flame retardant DM- 3070 (150g / L), N-methylolacrylamide (50g / L), wax emulsion DM-3260 (40g / L), 600 mesh magnesium hydroxide I (20g / L) and 9000 mesh magnesium hydroxide II ( 40g / L), prepare flame retardant working solution, then take Nylon Cotton camouflage cloth (blend ratio 50:50) two dipping two rolling flame retardant working solution (rolling liquid rate is about 60%), dry at 100 ℃, bake (160 °C×3min), then treated with potassium bromate (2.5g / L), followed by carbohydrazide (30g / L) to reduce formaldehyde, then washed with hot water and then washed with cold water to obtain a durable flame-retardant polyester-cotton fabric.

Embodiment 3

[0037] Take N-methylol-3-(dimethoxyphosphono)propionamide (300g / L), cotton flame retardant DM-3070 (150g / L), N-methylolacrylamide, silicone oil WS-3 (60g / L), 800-mesh magnesium hydroxide I (20g / L) and 10000-mesh magnesium hydroxide II (50g / L), prepare a flame-retardant working solution, and then take polyester-cotton gauze card (116×46, 20s×16s, Blending ratio 50:50) two-dipping and two-rolling flame retardant working solution (the rolling rate is about 60%), dry at 100°C, bake (150°C×3min), and then use 25% hydrogen peroxide (20g / L) and Catalyst DM-1435 (2g / L) treatment, followed by sodium bisulfite (40g / L) to capture formaldehyde on the cloth surface, followed by hot water washing, cold water washing, to obtain a durable flame-retardant polyester-cotton fabric.

Abstract

The invention provides a flame retardant tidying method for a purified cotton or blended cotton textile fabric. The method adopts a compound comprising four composites: composite A comprises at least one phosphorus compound; composite B comprises at least one phosphorus compound, composite C comprises at least one softening agent, composite D comprises magnesium hydroxide I and magnesium hydroxide II, the granule diameter of the magnesium hydroxide I is 600-1,000 meshes, and the granule diameter of the magnesium hydroxide II is 8.000-10,000 meshes. The method comprises the steps of soaking of the fabric in the compound and processing of heating, oxidizing, cleaning the fabric and reducing formaldehyde. The fabric has an excellent fire retardant effect, washability, low odor and a soft hand feeling.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a method for flame-retardant finishing of pure cotton or cotton blended fabrics. Background technique [0002] The flammability of cotton and polyester / nylon blended fabrics is greater than that of pure cotton and pure polyester / nylon, and its flame-retardant finishing technology is more difficult, especially for blended fabrics with high polyester / nylon content, the flame-retardant finishing of which still needs to be solved urgently industry problems. Due to the different combustion properties of polyester / nylon and cotton fibers, the combustion process becomes more complicated after blending. Polyester / nylon becomes a molten state when it burns, and the cotton fiber becomes a support after burning, so that the melt spreads 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,...
