Problems solved by technology

Because the application is to coat the flame-retardant coating on the surface of the fabric, on the one hand, the water-washing resistance of the flame-retardant coating is not strong, and with the increase of the number of washings, the flame-retardant performance will be more obvious; on the other hand, the flame-retardant coating It will affect the breathability and moisture permeability of the fabric

Embodiment 1

[0047] Antibacterial fiber is prepared by the following method:

[0048] (1) Add cellulose acetate into N,N-dimethylacetamide according to the solid-to-liquid ratio of 1g:20mL, stir at 150r / min at a constant temperature of 65°C to dissolve completely, add pyridine dropwise (the addition of pyridine The amount is 0.05% of the cellulose acetate mass);

[0049] (2) Transfer the above mixture to an ice-water bath, and when the temperature of the system drops to 0° C., slowly add sorbyl chloride dropwise under ice-water bath conditions (the amount of sorbyl chloride added is 40% of the cellulose acetate mass), and the dropwise After the last 15 minutes, the system was moved into a 65°C oil bath and stirred for 24 hours. After the reaction, the product was washed with deionized water and absolute ethanol until neutral to obtain modified acetate fiber;

[0050] (3) Dissolve modified cellulose acetate in N,N-dimethylacetamide, prepare a spinning solution with a mass fraction of 6%, a...

Embodiment 2

[0052] (1) Add cellulose acetate into N,N-dimethylacetamide according to the solid-to-liquid ratio of 1g:20mL, stir at 150r / min at a constant temperature of 65°C to dissolve completely, add pyridine dropwise (the addition of pyridine The amount is 0.05% of the cellulose acetate mass);

[0053] (2) Transfer the above mixture to an ice-water bath, and when the temperature of the system drops to 0° C., slowly add sorbyl chloride dropwise under ice-water bath conditions (the amount of sorbyl chloride added is 40% of the cellulose acetate mass), and the dropwise After the last 15 minutes, the system was moved into a 65°C oil bath and stirred for 24 hours. After the reaction, the product was washed with deionized water and absolute ethanol until neutral to obtain modified acetate fiber;

[0054] (3) Dissolve modified cellulose acetate in N,N-dimethylacetamide, prepare a spinning solution with a mass fraction of 6%, and add cellulose acetate (the amount of cellulose acetate added is ...

Embodiment 3

[0063] Flame retardant fibers are prepared by the following methods:

[0064] (1) Add terminal hydrogen-containing silicone oil and allylamine into a four-necked flask equipped with a thermometer, condenser, and magnetic stirrer according to the ratio of the amount of substances of 1:2.2, heat and stir slowly and raise the temperature to 50°C, Add catalyst chloroplatinic acid solution (the mass fraction of chloroplatinic acid solution is 6%, the mass of the added chloroplatinic acid solution is 0.1% of the total mass of terminal hydrogen-containing silicone oil and allylamine), then slowly heat up to 85°C, React for 4 hours, then obtain the flame retardant modifier through suction filtration and rotary evaporation;

[0065] (2) immerse the viscose fiber in an aqueous sulfuric acid solution with a mass fraction of 5%, soak it for 30 min at 40° C., then rinse the viscose fiber with distilled water until the lotion is neutral, and dry the viscose fiber to constant weight;

Abstract

The invention discloses environment-friendly flame-retardant textile fabric. The environment-friendly flame-retardant textile fabric is double-layer fabric, wherein the inner layer fabric is formed byweaving mulberry bark / antibacterial fiber blended yarn, the outer layer fabric is formed by weaving linen / flame-retardant fiber blended yarn, and the inner layer fabric and the outer layer fabric areconnected through polyester drawn textured yarn; and the fabric is formed by weaving the mulberry bark / antibacterial fiber blended yarn, the linen / flame-retardant fiber blended yarn and the polyesterdrawn textured yarn through a double-sided circular knitting machine. The environment-friendly flame-retardant textile fabric adopts the double-layer fabric, the inner layer fabric is breathable andmoisture-permeable and has an antibacterial function, the outer layer fabric has a flame-retardant effect, and the polyester drawn textured yarn plays the role of connection; antibacterial fiber is cellulose acetate fiber modified by the chemical grafting of sorbic acid chloride and has good antibacterial properties, flame-retardant fiber is viscose fiber which is chemically grafted with ethyl dichlorophosphate molecules and amino-terminated polysiloxane and has good flame retardant properties and mechanical properties, and the bonding form of chemical bonding is firm, and high washable performance is achieved; and the environment-friendly flame-retardant textile fabric has good breathability and moisture permeability and a wide application range.

Description

technical field [0001] The invention belongs to the technical field of functional fabrics, and in particular relates to an environmentally friendly flame-retardant textile fabric. Background technique [0002] Textile fabric is a common light industrial product in daily life. In the past, due to the low living standard, textile fabrics only needed to meet the characteristics of durability and good touch. Now, with the improvement of living standards, people tend to diversify the functions of textile fabrics. , The functional requirements for textile fabrics are also getting higher and higher. Functions similar to environmental protection functions have also become the needs of consumers. In addition, with the improvement of consumers' safety awareness, there are also requirements for the flame retardant performance of textile fabrics. [0003] The Chinese patent with the patent number CN201810461238.2 discloses a flame-retardant textile fabric, which includes a fabric substr...
