Problems solved by technology

[0005] Normal temperature dyeing of polyester refers to dyeing at a dyeing temperature below 100°C. At present, common polyester can be dyed at room temperature by adding carriers and other means, but the dyeing method using carriers has the disadvantages of large environmental pollution and difficult removal of carriers in the future. promotional use

Embodiment 1

[0053] Modified polyester and wool in the same color but different shades

[0054] The structure of described modified polyester is:

[0055] where 101 2 <70.

[0056] The fabric is a modified polyester / wool 30 / 70 blended fabric with a fabric weight of 185g / m 2 , the dye formula is: Acid Black 10B 1.5% (o.w.f), Yuanming powder 10g / L, leveling agent TF-217A 1.5g / L, adjust the pH value of the dyeing solution to 4.5 with citric acid and sodium citrate, and fabrics at 25°C Dyeing, then the dyeing solution is heated up to 100°C at a speed of 3°C / min, kept for 60 minutes, cooled and drained, and then washed with water. The color fastness of the dyed product is tested, and the color fastness of the dyed product is tested. Dry and wet grinding The color fastness is grade 4.

Embodiment 2

[0058] Modified polyester and wool completely different colors

[0059] The structure of described modified polyester is:

[0060] where 101 2 3 <5.

[0061] The fabric is a modified polyester / wool 50 / 50 blended knitted fabric with a fabric weight of 210g / m 2 , the dye solution formula is: disperse red FB 0.5% (o.w.f), weak acid bright yellow 5G 1.2%, use glacial acetic acid and sodium acetate to adjust the pH value of the dye solution to 4~5, the fabric is dyed at 40 ° C, and then the dye solution is heated at 2 ° C Heat up to 100°C at a speed of 1 / min, keep warm for 45 minutes, cool down and drain, and then wash with water. The color fastness of the dyed product is tested. The color fastness to dry rubbing is grade 4-5, and the color fastness to wet rubbing is grade 4.

Embodiment 3

[0063] Modified polyester and wool are exactly the same color

[0064] The structure of described modified polyester is:

[0065] 101 2 <70.

[0066] The fabric is a modified polyester / wool 40 / 60 blended knitted fabric with a fabric weight of 220g / m 2 , the color sample K / S value is 12.6, according to the computer color matching database, wool dyeing, only use weakly acidic black BR ​​can meet the color sample color requirements, its consumption is 1.8%, according to the formula in the present invention to calculate the required amount of modified polyester Apparent depth value Δ(K / S) complemented by disperse dyes D is 5.76 (correction coefficient F is 1.2), and the calculated dye dosage in the final dye solution formula is: weak acid black BR ​​1.47%, disperse black 0.4%.

[0067] The formula of the dyeing solution is: Disperse Black 0.4% (o.w.f), Weak Acid Black BR ​​1.47%, Leveling Agent TF-217A 0.5~1.0g / L, Yuanmingfen 8g / L, adjust the dyeing solution with glacial acet...

Abstract

The invention provides a modified polyester / wool blended fabric, which is formed by blending modified polyester and wool. The modified polyester structurally comprises the following structural units:, wherein m1 is more than 1 but less than 160; m2 is more than 1 but less than 70; m3 is not less than 0 but less than 20; and m4 is not less than 0 but less than 20; the blended fabric can be one-bath dyed with acidic dye or acidic dye and disperse dye, thus dyeing procedures are simplified, energy conservation and pollution reduction is saved, and energy consumption can be prominently reduced owing to the dyeing temperature below 100 DEG C.

Description

technical field [0001] The present invention relates to a method for dyeing polyester / wool blended fabrics, in particular to a method for one-bath dyeing of polyester / wool blended fabrics, more specifically, to a method for one-bath dyeing of modified polyester / wool blended fabrics method. Background technique [0002] As the basic industry of the textile industry, chemical fiber has always been a key industry in my country's planning and development, especially with the increase in the use of polyester staple fiber in the preparation of fine-woven fabrics such as wool and polyester, the amount of this aspect accounts for a large share of the total output of polyester staple fiber . Therefore, it is very meaningful to research and develop the dyeing technology of polyester and wool blending. [0003] Wool / polyester blended fabric not only has the strength of polyester and the crispness of fabric, but also has the moisture absorption and plump feel of wool fabric. To a certa...
