Embodiment 1

[0037] In this example, a polyphenylene sulfide multi-component blended flame-retardant fabric is prepared, which is composed of the following components in terms of mass percentage: 40% polyphenylene sulfide fiber, 20% melamine fiber, 40% aramid fiber, The structure of the fabric is three centimeters of plain weave, and the mass per unit area of ​​the finished product is 300g / m 2 .

[0038] The prepared fabric is dyed, specifically implemented according to the following steps:

[0039] Step 1: desizing and scouring the fabric, using the pad steaming method to descale one bath, the desizing enzyme concentration is 2g / L, the steaming temperature is 100°C-102°C, and the steaming time is 60min.

[0040] Step 2, configure the dye solution. The dye solution formula is: acid black BL3.5% (relative to fabric weight), disperse black ECO10.0% (relative to fabric weight), cationic black FDL 7.0% (relative to fabric weight), Yuanming powder 30g / L ( Relative to the total volume of the ...

Embodiment 2

[0043] In this example, a polyphenylene sulfide multi-component blended flame-retardant fabric is prepared, which is composed of the following components by mass percentage: 80% polyphenylene sulfide fiber, 10% melamine fiber, 10% aramid fiber, The structure of the fabric is plain weave three centimeters, and the mass per unit area of ​​the finished product is 245g / m 2 .

[0044] The prepared fabric is dyed, specifically implemented according to the following steps:

[0045] Step 1: desizing and scouring the fabric, using the pad steaming method to descale in one bath, the desizing enzyme concentration is 2g / L, the steaming temperature is 100°C-102°C, and the time is 50min.

[0046] Step 2, configure the dye solution. The dye solution formula is: acid blue TBF 2.0% (relative to fabric weight), disperse blue 2BLN9.5% (relative to fabric weight), cationic blue FGL 2.0% (relative to fabric weight), NaCl 40g / L (relative to dyeing The total volume of the dye solution), acetophen...

Embodiment 3

[0049] In this example, a polyphenylene sulfide multi-component blended flame-retardant fabric is prepared, which is composed of the following components in terms of mass percentage: 20% polyphenylene sulfide fiber, 50% melamine fiber, 30% aramid fiber, The structure of the fabric is twill three centimeters, and the mass per unit area of ​​the finished product is 220g / m 2 .

[0050] The prepared fabric is dyed, specifically implemented according to the following steps:

[0051] 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.

[0052] Step 2, configure the dye solution. The formula of the dyeing solution is: acid black BL5.0% (relative to the weight of the fabric), disperse black ECO2.8% (relative to the weight of the fabric), cationic black FDL 3.0% (relative to the weight of the fabric), NaNO 3 50g / L (relative to the tota...

Abstract

The invention discloses a polyphenylene sulfide multi-component blended flame-retardant fabric which is blended with polyphenylene sulfide fibers and aramid fibers. It further includes melamine fibers. The dyeing process of the fabric is also disclosed. Firstly, the fabric is desized and scoured by using the one-bath process of rolling and steaming; then the fabric is immersed in a dye solution for dyeing. and adjust the acidity and alkalinity through a pH regulator; when the fabric is made of polyphenylene sulfide fiber and aramid fiber, the dye is composed of disperse dyes and cationic dyes; when the fabric is made of polyphenylene sulfide fiber, melamine fiber and When aramid fibers are blended, the dyes are composed of disperse dyes, acid dyes and cationic dyes. The fabric of the present invention has good flame retardancy, high temperature resistance, high-strength tear resistance, beautiful fabric style, good color fastness, high dye uptake rate, and good color fastness, which can meet the requirements of the fabric in the field of safety and protective clothing. application.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a polyphenylene sulfide multi-component blended flame-retardant fabric, and also relates to a dyeing process of the polyphenylene sulfide multi-component blended flame-retardant fabric. Background technique [0002] In recent years, the global safety and protection textile market has shown a rapid growth trend, and the market demand for high-performance fibers and fabrics has increased significantly, and they are widely used in fire protection, police, welding, petrochemical and other fields. Safety protective clothing and fabrics should not only have good flame retardancy and high temperature resistance, but also have good tear resistance and wear resistance. In order to meet the identification and aesthetic requirements of clothing in different industries, the color and color fastness The requirements are also very high, and as a garment, it should also have good w...
