Problems solved by technology

[0003] At present, the dyeing process of Tencel / T fabric is extremely immature, which not only consumes time and energy, but also the quality of the dyed fabric is poor, and it is prone to dyeing defects such as color spots, and more hairiness, especially when dyed in emerald blue and emerald green. The problem of bright color series is more prominent

Embodiment 1）

[0012] The method of dyeing the fabric containing polyester fiber and tencel fiber of the present embodiment has the following steps:

[0013] ① Refining and dyeing polyester fiber at the same time: directly immerse the fabric containing polyester fiber and tencel fiber into the dye vat filled with the first dye solution, and refine and dye the polyester fiber at the same time at a temperature of 130°C for 30 minutes.

[0014] The fabric used in this example is Tencel / T single jersey fabric interwoven with 65% Tencel (60S) and 35% polyester (50D / 36F).

[0015] The pH value of the first dyeing solution is 4.5, which contains 0.582g disperse dye, 1g glacial acetic acid, 0.5g refining agent, 1g refining emulsifier, 3g softening agent in cotton bath, 1g softening agent in washing bath and 1g dispersing dye per liter. an aqueous solution of leveling agent; and the total weight of disperse dyes is 0.291% by weight of the fabric.

[0016] The disperse dyes used are disperse yellow H...

Abstract

The invention discloses a method for dyeing a fabric containing polyester fiber and a tencel fiber. The method comprises the following steps of: (1)carrying out refining and polyester fiber dyeing to the fabric containing the polyester fiber and the tencel fiber in the first dyeing liquid containing dispersed dye and a refining agent for 20 to 40 minutes at 120 to 140 DEG C; (2) carrying out tencel fiber dyeing to the fabric dyed by the polyester fiber in the second dyeing liquid containing reactive dye for 45 to 75 minutes at 50 to 70 DEG C; and (3) processing the dyed fabric through pickling, soaping, pickling and hair removing in sequence. With the adoption of the method disclosed by the invention, dyeing time is shorter, water consumpton is less, therefore, energy consumption is greatly reduced; and moreover, the surface of the dyed fabric is smooth and clean and has no filoplume as well as no dyeing defect; quality of the fabric is promoted; and the method specifically has an obvious dyeing effect on bright color series, such as emerald green and bright blue.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a method for dyeing fabrics containing polyester fibers and tencel fibers. Background technique [0002] Tencel fiber (Tencel) has the characteristics of soft drape, unique touch, elegant and dynamic, breathable and moisture-permeable, and elegant luster; while polyester fiber is relatively stiff and has good shape retention. The fabric combined with two fibers (Tencel / T fabric) has the advantages of both, so it has a very wide range of applications. [0003] At present, the dyeing process of Tencel / T fabric is extremely immature, which not only consumes time and energy, but also the quality of the dyed fabric is poor, and it is prone to dyeing defects such as color spots, and more hairiness, especially when dyed in emerald blue and emerald green. The problem of bright color series is more prominent. Contents of the invention [0004] The object of the p...
