Embodiment 1

[0018] A green and environmentally friendly method for improving the flame resistance of cotton fabrics. The process formula: the flame retardant is polytriphosphazene, the dosage is 50g / L; the liquor ratio is 1:3; the temperature is normal temperature; the spraying method is adopted, and the temperature is constant Place in a wet chamber to equilibrate for 1h. After the fabric is treated, it is tested according to GB / T 2406-1993, and the limiting oxygen index is 35; it is tested according to GB 4609-1984, and after burning for 12 seconds, the afterburning time is 0 seconds.

Embodiment 2

[0020] A green and environmentally friendly method for improving the flame resistance of cotton fabrics. The process formula: the flame retardant is polyaryloxyphosphazene, the dosage is 50g / L; the bath ratio is 1:3; the temperature is normal temperature; the spraying method is adopted. Place in a constant temperature and humidity chamber to balance for 1h. After the fabric is treated, it is tested according to GB / T 2406-1993, and the limiting oxygen index is 32; it is tested according to GB 4609-1984, after burning for 12 seconds, the afterburning time is 2 seconds.

Embodiment 3

[0022] A green and environmentally friendly method for improving the flame retardancy of cotton fabrics. The process formula: the flame retardant is polyfluoroalkoxyphosphazene, the dosage is 50g / L; the bath ratio is 1:3; the temperature is normal temperature; the spray method is adopted Process, placed in a constant temperature and humidity room to balance for 1h.

Abstract

The invention discloses an environment-friendly method for improving fire resistance of cotton fabric. The method comprises the following steps: selecting a flame-retardant reagent, and preparing a finishing liquid with certain concentration, wherein the formula of the finishing liquid comprises 5-400g / L of a polyphosphazene fire retardant and 0-20g / L of a super softening agent; transferring the fishing liquid into a spraying device, and evenly spraying on the cotton fabric, wherein the amount of the finishing liquid is 1%-30% of mass of the fabric; and putting the cotton fabric into a constant-temperature and constant-humidity room for 5-120 minutes, drying, roasting and then testing. The cotton fabric is processed by a spraying life-nourishing method. Compared with a traditional impregnating or padding operation method, the amount of the finishing liquid can be greatly reduced; the cost is reduced; emission of wastewater is reduced; the fire resistance of the finished cotton fabric is improved; and the fire retardant adopted by the technique is a halogen-free reagent, so that the cotton fabric is ecological, environmentally friendly, free of pollution to environment, low in price, simple in process and convenient to operate.

Description

technical field [0001] The invention belongs to the field of textile dyeing and finishing, and in particular relates to a green and environment-friendly finishing method that can effectively improve the flame-retardant performance of cotton fabrics. Background technique [0002] Cotton fabric has excellent wearing properties and is widely used in clothing and interior decoration. A lot of research has been done on the combustibility and flame-retardant finishing of cotton fabrics at home and abroad, but it is still difficult to meet the requirements of some applications. The ideal durable flame retardant for cotton fabrics still needs further research and development. [0003] People have more and more stringent requirements on the performance of flame retardants, not only focusing on their primary fire performance, but also on secondary fire performance, that is, the smoke and various corrosive or toxic gases released during combustion. In the past few years, countries aro...
