Embodiment 1

[0031] Soak 65 / 35 polyester-cotton fabric in 2g / L dopamine aqueous solution, treat at 35°C for 24 hours, take out the fabric, wash with water, and dry to obtain light brown polyester-cotton fabric. Prepare a sodium phytate aqueous solution with a mass fraction of 1.5%, and adjust the pH value to 2. Immerse the dopamine-treated light brown polyester-cotton fabric in the above sodium phytate aqueous solution, take it out after soaking for 15 minutes, rinse, and dry; Take it out after 5 minutes, rinse and dry. Thereafter, alternately immerse in sodium phytate aqueous solution and chitosan aqueous solution for 5 minutes each, repeat dipping, rinsing, and drying, and do a total of 15 alternate dippings to obtain colored flame-retardant polyester-cotton fabrics. According to the oxygen index method of GB / T5454-1997 textile combustion performance test, the oxygen index of the colored flame-retardant polyester-cotton fabric is 28.6%, while the oxygen index of the 65 / 35 polyester-cott...

Embodiment 2

[0033] Soak 45 / 55 polyester-cotton fabric in 1.5g / L dopamine aqueous solution, treat at 35°C for 24 hours, take out the fabric, wash with water, and dry to obtain light brown polyester-cotton fabric. Prepare a sodium phytate aqueous solution with a mass fraction of 2%, adjust the pH value to 3, immerse the dopamine-treated light brown polyester-cotton fabric in the above-mentioned sodium phytate aqueous solution, soak for 15 minutes, take it out, rinse, and dry. Then immerse in a chitosan solution with a pH value of 5 and a mass fraction of 1%, take it out after 5 minutes of immersion, rinse, and dry, then alternately immerse in sodium phytate aqueous solution and chitosan aqueous solution for 5 minutes each, repeat dipping and rinsing. Washing, drying, and doing 20 alternate impregnations altogether, obtain colored flame-retardant polyester-cotton fabric. According to the oxygen index method of GB / T5454-1997 textile combustion performance test, the oxygen index of the colored...

Abstract

The invention relates to a preparation method for a colored anti-flaming polyester-cotton fabric. The preparation method comprises the following steps: dipping a polyester-cotton fabric in a dopamine aqueous liquid at 35-40 DEG C; then taking out the polyester-cotton fabric; washing with water and drying, thereby acquiring a colored polyester-cotton fabric; dipping the colored polyester-cotton fabric in a sodium phytate aqueous liquid with pH value within the scope of 2-3 for 10-15min, leaching and drying; dipping the dried colored polyester-cotton fabric in a chitosan aqueous liquid with the pH value within the scope of 5-5.5, leaching and drying; alternately dipping the treated polyester-cotton fabric into the sodium phytate aqueous liquid and the chitosan aqueous liquid for 15-20 times, dipping for 5-8min each time, and leaching and drying the polyester-cotton fabric after being dipped at each time, thereby acquiring the colored anti-flaming polyester-cotton fabric. The invention also claims for protecting the colored anti-flaming polyester-cotton fabric prepared according to the method. The color is gradually from brown to hazel. The preparation method provided by the invention has the advantages of environment-friendly raw materials, easy practicable operation and low energy consumption. The prepared colored anti-flaming polyester-cotton fabric has excellent anti-flaming property and physical and mechanical properties and suitability for industry application.

Description

technical field [0001] The invention relates to the technical field of textile finishing, in particular to a colored flame-retardant polyester-cotton fabric and a preparation method thereof. Background technique [0002] Polyester-cotton blended fabrics are widely used in labor protective clothing, firefighting clothing, military combat uniforms, bedding and interior decoration fabrics due to their crisp appearance, easy washing and quick drying, breathable comfort and high strength, with a huge market share. Most polyester-cotton products need flame-retardant finishing to meet different degrees of fire protection requirements. However, since polyester-cotton blended fabrics are more flammable than pure cotton and polyester, and burn more violently than single cotton or polyester components, the flame-retardant treatment of polyester-cotton fabrics has always been a difficult problem in the industry. The widely accepted explanation that polyester and cotton are easier to bu...
