Embodiment 1

[0032] In this example, a melamine blended flame-retardant fabric is prepared. The fabric is composed of the following components in terms of mass percentage: 80% melamine fiber and 20% polyphenylene sulfide fiber. The mass per unit area of ​​the finished product is 155g / m 2 .

[0033] The prepared fabric is dyed, specifically implemented according to the following steps:

[0034] Step 1. Desizing and scouring the fabric, using the pad-steaming one-bath process, the desizing enzyme concentration is 3.5g / L, the steaming temperature is 100°C-102°C, and the steaming time is 60min.

[0035] Step 2, configure the dye solution. The dye solution formula is: acid blue TBF 0.8% (relative to the fabric weight), disperse blue 2BLN0.2% (relative to the fabric weight), NaCl 30g / L, dimethyl phthalate 50g / L, acetic acid to adjust the pH value 2~3.

Embodiment 2

[0038] In this example, a melamine blended flame-retardant fabric is prepared. The fabric is composed of the following components in terms of mass percentage: 80% polyphenylene sulfide fiber and 20% melamine fiber. The mass per unit area of ​​the finished product is 240g / m 2 .

[0039] The prepared fabric is dyed, specifically implemented according to the following steps:

[0040] Step 1. Desizing and scouring the fabric, using the pad steaming method to descale one bath, the desizing enzyme concentration is 5g / L, the steaming temperature is 100°C-102°C, and the steaming time is 40min.

[0041] Step 2, configure the dye solution. The formula of the dyeing solution is: acid black BL1.6% (relative to the weight of the fabric), disperse black ECO10.0% (relative to the weight of the fabric), 40g / L of sodium sulfate, 40g / L of dimethylformamide, citric acid adjustment The pH value is 2-3.

Abstract

The invention discloses a melamine blended flame-retardant fabric, which is formed by blending melamine fibers and polyphenylene sulfide fibers. The dyeing process of the fabric is also disclosed. Firstly, the fabric is desized and scoured by the one-bath process of rolling and steaming; then the fabric is immersed in a dye solution for dyeing. It is mixed with a carrier, and the acid-base is adjusted by a pH regulator. After dyeing, the fabric is washed and dried. The fabric of the present invention has good safety protection properties such as flame retardancy, high temperature resistance, and high-strength tear resistance, and the fabric is comfortable to wear, beautiful in style, good in color fastness, high in dyeing rate, and good in various color fastnesses, which can meet The application of fabrics in the field of safety and protective clothing.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a melamine blended flame-retardant fabric, and also relates to a dyeing process of the melamine blended flame-retardant fabric. Background technique [0002] As the country increases investment in national defense security and social security, as well as the emphasis on labor protection and life safety, the safety and protection textile industry has developed rapidly. High-performance protective textiles have become the key development direction of the security industry. At present, most of the domestic and foreign markets are made of aramid fiber. Aramid fiber has excellent flame retardancy, high temperature resistance and physical and mechanical properties, but the cost is high and dyeing is difficult. According to my country's national conditions, it is not suitable for large-scale production. Promote apps. There is currently a lack of a fabric that is functional...
