Problems solved by technology

In recent years, some new silicon-based and boron-based flame retardants have also appeared. CN101413214A introduces silicon into phosphorus / nitrogen flame retardants. The synergistic effect of silicon flame retardants can reduce the amount of phosphorus flame retardants, but it does not Fundamentally solve the problem of using phosphorus flame retardants

Embodiment 1

[0011] Add 25g of cotton fabric to 400mL of sodium hydroxide (0.05g / mL) in ethanol solution, and alkalize the fabric at 60°C for 4h. After the alkalization was completed, 20 g of chloroacetic acid was added into the reaction vessel, and stirred to dissolve it. After etherification at 65°C for 3 hours, add 10g of sodium hydroxide for secondary alkalinization, after 2 hours of reaction, neutralize with acetic acid to pH = 7, wash twice with 70% ethanol aqueous solution, and wash with 90% ethanol Once, a flame-retardant cotton fabric with a sodium ion content of 4.40% was obtained after drying. The flame-retardant cotton fabric is ignited with a fire source, and extinguished after leaving the fire source. The limiting oxygen index is 27.0%.

Embodiment 2

[0013] Add 25g of cotton fabric to 400mL of sodium hydroxide (0.08g / mL) in ethanol solution, and alkalize the fabric at 60°C for 4h. After alkalization was completed, 30 g of chloroacetic acid was added into the reaction vessel, and stirred to dissolve it. After etherification at 65°C for 3 hours, add 15g of sodium hydroxide for secondary alkalinization, after 2 hours of reaction, neutralize with acetic acid to pH = 7, then wash twice with 70% ethanol aqueous solution, and 90% ethanol Once, a flame-retardant cotton fabric with a sodium ion content of 6.39% was obtained after drying. The flame-retardant cotton fabric is ignited with a fire source, and extinguished after leaving the fire source. The limiting oxygen index is 35.0%.

Embodiment 3

[0015] Take 25g of the cotton fabric modified by sodium ion flame retardant in Example 2, use 400mL of ethanol as the medium, add 30g of calcifying agent and stir to dissolve it, react at 60°C for 4h, wash twice with 70% ethanol aqueous solution, 90 % ethanol, washed once, and dried to obtain a flame-retardant cotton fabric with a calcium ion content of 2.27%. It is ignited with a fire source and self-extinguishes after leaving the fire source. The limiting oxygen index is 28.5%.

Abstract

The invention relates to a preparation method of a metal ion flame retardant modification cotton fabric. The method comprises the steps that 1), metal irons are introduced into the cotton fabric in a chemical manner, so that the durable flame-retarding cotton fabric is obtained; and 2), metal compounds are adsorbed onto the cotton fabric in a physical manner. The method has the advantages that flame retardants are wide in variety range and can be obtained easily, the flame retardant modification operation is simple, the flame retardant effect is obvious, and the like. Even if an ordinary person comes across a fire, the person can adopt the method for treating cotton fabrics (clothes, quilts, bed sheets and the like), so that a flame retardant and fireproof protection product is obtained, and damages of the fire to persons and property are reduced. The preparation method takes metal ions or metal compounds as the fire retardants of the cotton fabric, is a brand new flame retardant method and technology, and can avoid usage of phosphorus, nitrogen and halogen flame retardants and reduce environmental pollution caused in processes of production and usage and after abandon.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant textiles, in particular to a preparation method of metal ion flame-retardant modified cotton fabrics. Background technique [0002] Cotton fabric is a natural, renewable and environmentally friendly textile and clothing material. It has the advantages of good skin contact, comfortable wearing, and good hygroscopicity. Therefore, it is still irreplaceable by synthetic fiber fabrics in the fields of textile and clothing. But cotton fabric is very flammable, and it is easy to become a fire point to cause a fire, especially as cotton products such as clothing and bed sheets used by children, the elderly and patients, which are more likely to cause personal injury when encountering a fire. The fires caused by it are also increasing, so countries have successively proposed flame-retardant requirements for cotton textiles. [0003] The flame retardant of cotton fabric is mainly modified by post-...
