Embodiment 1

[0035] A new type of fiber stock solution color paste, prepared from pre-emulsion, adipic hydrazide aqueous solution and initiator solution as raw materials:

[0036] The pre-emulsion is prepared from the raw materials of the following parts by mass shown in Table 1:

[0037]

[0038] Table 1

[0039] The concentration of the aqueous solution of adipic hydrazide was 8 wt%.

[0040] The initiator solution is obtained by mixing 1.2 parts by mass of potassium persulfate, 1.0 parts by mass of sodium bisulfite, 12.8 parts by mass of deionized water, and 2.0 parts by mass of propylene glycol.

[0041] A preparation method for fiber stock liquid color paste, comprising the steps of:

[0042] 1) Weigh the toner phthalocyanine blue 15:3, dispersant TEGO750w, reactive emulsifier, water, mix and ultrasonically disperse for 0.5h, then add buffer sodium bicarbonate, special monomer hydroxyethyl methacrylate phosphate and deionized water, mixed and stirred for ultrasonic emulsificatio...

Embodiment 2

[0047] A new type of fiber stock solution color paste, prepared from pre-emulsion, adipic hydrazide aqueous solution and initiator solution as raw materials:

[0048] The pre-emulsion is prepared from the raw materials of the following parts by mass shown in Table 2:

[0049]

[0050] Table 2

[0051] The aqueous solution of adipic hydrazide is obtained by dissolving 0.8-1.6 parts by mass of adipic hydrazide in 8-10 parts of deionized water.

[0052] The initiator solution is obtained by mixing 1.2 parts by mass of potassium persulfate, 1.0 parts by mass of sodium bisulfite, 12.8 parts by mass of deionized water, and 2.0 parts by mass of propylene glycol.

[0053] A preparation method of a new type of fiber stock solution color paste, the difference from Example 1 is that step (1) ultrasonic emulsification for 0.5h, to obtain a pre-dispersion.

Embodiment 3

[0055] A new type of fiber stock solution color paste, prepared from pre-emulsion, adipic hydrazide aqueous solution and initiator solution as raw materials:

[0056] The pre-emulsion is prepared from the raw materials of the following parts by mass shown in Table 3:

[0057] table 3

[0058]

[0059]

[0060] The aqueous solution of adipic hydrazide is obtained by dissolving 0.8-1.6 parts by mass of adipic hydrazide in 8-10 parts of deionized water.

[0061]The initiator solution is obtained by mixing 1.2 parts by mass of potassium persulfate, 1.0 parts by mass of sodium bisulfite, 12.8 parts by mass of deionized water, and 2.0 parts by mass of propylene glycol.

[0062] The preparation method is different from Example 1 in that after adding 20% ​​acrylate monomer in step (2), heat to 55°C, add the remaining acrylate monomer and initiator solution dropwise, and start the function of dropping at the same time When monomer is used, the temperature is controlled at 60°C....

Abstract

The invention discloses a method for preparing a novel environment-friendly fiber stock solution color paste. The color paste is prepared from pre-emulsion liquid wrapped with pigments, adipic hydrazide aqueous solution and initiator solution as raw materials. When adding monomers and initiator solution The temperature is controlled at 55-60°C, and the reaction is carried out for 4-5 hours after the addition is completed, and the method of batch addition is adopted. The fiber stock liquid color paste obtained by the present invention has more excellent coloring effect, excellent color fastness to light, and color fastness to weathering, and does not require chemical dyeing, tow dyeing or gel dyeing of subsequent fibers or fabrics, and reduces pollution of the environment.

Description

technical field [0001] The invention belongs to the technical field of fine chemical coatings, and in particular relates to a preparation method of a novel environment-friendly fiber stock solution color paste. Background technique [0002] With the continuous expansion of environmental hazards, under the social background of depleting energy and water resources and increasing pressure on environmental protection, how to avoid high energy consumption and high pollution in the printing and dyeing process is an important issue related to the survival of the textile industry. In the traditional coloring process of fiber raw materials, the exhaustion rate of cationic dyes is low, the dye consumption is high, and the environmental pollution is serious; at the same time, due to the structural reasons of the dyes, it is difficult to accurately match colors; The color fastness, soaping color fastness and rubbing color fastness are poor. Due to the relatively low price and convenien...
