Problems solved by technology

However, the coloring components used in pigment printing are generally pigments, which have no affinity with fibers and need to be adhered to the surface of fibers through adhesives, and the color generally cannot penetrate into the interior of the fibers, which causes the general color of pigment printing products to pass through. Poor permeability, not bright color, poor color fastness, not washable, hard hand feeling, poor yellowing resistance, etc.

Embodiment 1

[0237] (1) Preparation of Dyeing and Coating Integrated Dyeing and Printing Dye Composition 1

[0238] Add 45g of surfactant LS-70, 50g of sodium lignosulfonate, 30g of ethylene glycol and 525g of water into the dispersion tank, disperse and stir to make it completely dissolved, and then add 350g of the following structural dyes:

[0239]

[0240] Start the disperser, disperse at high speed for 2 hours, put the dispersed slurry into a horizontal sand mill for circular grinding, the grinding time is 10 hours, after the grinding is completed, the slurry obtained by grinding is homogenized twice through a high-pressure homogenizer to obtain Dye dyeing and coating integrated dyeing and printing dye composition 1, 1000g, fineness d50≤0.5μm, pH=6.8.

[0241] (2) Preparation of integrated dyeing and printing auxiliaries

[0242] Add 227g of deionized water into the dispersing tank, turn on the dispersing machine, and under low-speed stirring, add 15g of surfactant FC-1, 30g of pe...

Embodiment 2-22

[0248] According to the preparation process of the above-mentioned embodiment 1 (step 1), the dyeing and coating integrated dyeing and printing dye composition (2-22) are prepared, only the dyes in the above-mentioned embodiment 1 are carried out by using the dyes of different structures recorded in the following table replace. Then further obtain dyeing and coating integrated dyeing and printing paste 2-22, use the obtained dyeing and printing paste to carry out flat screen printing, and then test the various properties of the printed product. The structure and performance data of the dye used are as follows:

[0249]

[0250]

Embodiment 23

[0252] Preparation of dyeing and printing paste 23 integrated with dyeing and coating

[0253] Add 960g of deionized water into the dispersing tank of the disperser, start the disperser, slowly add thickener PF20g under high-speed stirring, and add dyeing and coating integrated dyeing and printing dye composition 1 (prepared in Example 1), 20g after stirring evenly , after dispersing and stirring evenly, obtain dyeing and coating integrated dyeing, printing paste 23, 1000g, viscosity 2320mPa.S (NDJ-1 rotational viscometer, 3# rotor, 30r / min)

[0254] The prepared dyeing-coating-integrated dyeing and printing paste is used for flat screen printing. The printing process is: textile → printing → drying → baking → finishing → printed product, wherein: the drying temperature is 100 ° C for 10 minutes, and the baking temperature is 180 ° C. ℃, 3 minutes. The test data of the printed products are as follows:

Abstract

The invention discloses a dye composition for disperse dye dyeing and printing. The dye composition is used for disperse dye and pigment integrated dyeing or printing and composed of azeo, anthraquinone or heterocycle disperse dye, auxiliaries and water. By refining of the composition, a disperse dye composition for dye and pigment integrated dyeing or printing is prepared and can be matched with dye and pigment integrated dyeing and printing auxiliaries, a thickening agent and water to prepare paste for dye and pigment integrated dyeing and printing. The paste used for dyeing and printing of hydrophobic textile materials integrates advantages of dye dyeing and printing and pigment dyeing and printing, high fastness to dry and wet rubbing, water washing and sublimation can be guaranteed while color brightness and softness are achieved; in addition, high-concentration color water generated in a traditional disperse dye dyeing and printing process can be avoided. Therefore, the product is a clean and environment-friendly product for dye dyeing and printing.

Description

technical field [0001] The invention relates to textile dyeing and printing technologies, in particular to a dye slurry composition for dyeing and coating integrated dyeing and printing. Background technique [0002] Textile dyeing and printing can generally be divided into dye dyeing, printing and pigment dyeing and printing. Dyeing and printing are usually carried out through the intermolecular force of the dye itself or the interaction between the active group and the fiber. Pigment dyeing and printing are combined with the fabric in a physical bonding manner through the binder in pigment dyeing and printing paste. Generally speaking, the dyed and printed products obtained after dye printing are more environmentally friendly, with low formaldehyde content, bright color, good color fastness, soft hand feeling, and non-sticky printing parts; pigment printing process is simple, printing cost is low, and there are basically no three wastes produce. [0003] The traditional...
