Embodiment 1

[0036] Use acrylic chloride fiber / flame retardant viscose / flame retardant polyester blended flame retardant fabric, weight 200g / m 2 ;

[0037] Step 1. Desizing and scouring the acrylic / flame retardant viscose / flame retardant polyester blended flame retardant fabric gray fabric with an overflow dyeing machine, the desizing enzyme concentration is 2g / L, and the degreasing agent is 1g / L; The scouring temperature is 80°C and the time is 20 minutes; then wash with cold water and prepare for dyeing;

[0038] Step 2. In the overflow dyeing machine, first use disperse dyes to dye the flame-retardant polyester and acrylic fiber treated in step 1. The dyeing heating process includes: the initial dyeing temperature is 40°C, and the temperature is raised to 1.5°C / min. 100°C, the holding time is 50min; then cool down to 60°C at 2°C / min, and soap with a concentration of 1g / L soaping solution at a temperature of 80°C. Reactive dyes are then used to dye the flame retardant viscose. The hea...

Embodiment 2

[0043] Flame-retardant polyester / acrylic / flame-retardant viscose blended flame-retardant fabric is selected, with a weight of 180g / m 2 ;

[0044] Step 1. Desizing and scouring the acrylic / flame retardant viscose / flame retardant polyester blended flame retardant fabric gray fabric with an overflow dyeing machine, the concentration of desizing enzyme is 5g / L, and the degreasing agent is 2g / L; The scouring temperature is 90°C and the time is 20 minutes; then wash with cold water and prepare for dyeing;

[0045] Step 2. In the overflow dyeing machine, first use disperse dyes to dye the flame-retardant polyester and acrylic fiber treated in step 1. The dyeing heating process includes: the initial dyeing temperature is 40°C, and the temperature is raised to 1°C / min. 95°C, the holding time is 45min; then cool down to 60°C at 2°C / min, and soap with a concentration of 1g / L soaping solution at a temperature of 80°C. Reactive dyes are then used to dye the flame retardant viscose. The ...

Embodiment 3

[0050] Use acrylic chloride fiber / flame retardant viscose / flame retardant polyester blended flame retardant fabric, weight 200g / m 2 ;

[0051] Step 1. Desizing and scouring the acrylic / flame retardant viscose / flame retardant polyester blended flame retardant fabric gray fabric with an overflow dyeing machine, the desizing enzyme concentration is 2g / L, and the degreasing agent is 1g / L; The scouring temperature is 80°C and the time is 10 minutes; then wash with cold water and prepare for dyeing;

[0052] Step 2. In the overflow dyeing machine, first use disperse dyes to dye the flame-retardant polyester and acrylic chloride fiber treated in step 1. The dyeing heating process includes: the initial dyeing temperature is 45°C, and the temperature is raised to 2°C / min. 105°C, the holding time is 60min; then cool down to 60°C at 2°C / min, and soap with a concentration of 2g / L soaping solution at a temperature of 90°C. Reactive dyes are then used to dye the flame retardant viscose. ...

Abstract

The invention discloses a modacrylic / flame retardant viscose / flame retardant polyester blended flame retardant fabric dyeing technology which includes the steps: desizing and scouring a modacrylic / flame retardant viscose / flame retardant polyester blended flame retardant grey fabric; dyeing the treated fabric by the aid of disperse dyes and active dyes; performing after-finishing on the dyed fabric. Flame retardant polyester and modacrylic are dyed by a disperse dye carrier method, the time of two-bath dyeing of two fibers by the disperse dyes and cationic dyes is shortened, dyeing efficiency can be improved, reserve of workshop dye types is decreased, and factory capital backlog is reduced.

Description

technical field [0001] The invention belongs to the technical field of dyeing process and relates to a dyeing process of acrylic / flame retardant viscose / flame retardant polyester 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, although they are widely used in special fields such as fire protection, police, welding, and petrochemicals. However, due to the high price of high-performance fibers, it is difficult to be widely used in a wide range. As one of the important functional fibers, flame-retardant polyester has its unique advantages—permanent flame retardancy and low price. Its fiber fabrics and blended fabrics are widely used in clothing, curtains, curtains, bedding, vehicle interior materials and other fields, and can even be used in special fields such as fire protectio...
