Problems solved by technology

Through the above printing and dyeing process, although the printing and dyeing of knitted cloth can be realized, in the scouring and bleaching of knitted cloth, sodium sulfite and sodium dodecylbenzene sulfate in the scouring agent are dissolved in water, and ionized to produce sulfite anion, Dialkylbenzenesulfate anion, sulfite anion, and dodecylbenzenesulfate anion greatly reduce the amount of positive charges on the surface of knitted fabrics, thereby affecting the color yield of knitted fabrics

[0051] Preparation Example of Compound Fiber Positive Charge Protector

[0052] The composite fiber positive charge protector is prepared by the following method: adding sodium ethylenediamine tetramethylene phosphonate and diethylene triamine pentamethylene phosphonic acid to water, then adding non-ionic penetrant, methyl maleate acrylate Copolymer and isomeric alcohol polyoxyethylene ether are uniformly mixed to obtain a composite fiber positive charge protector.

Embodiment 1

[0054] A knitted fabric printing and dyeing pretreatment solution. The raw materials of the pretreatment solution include water and a pretreatment agent. The water is a solvent and the pretreatment agent is a solute. The raw material ratio of the pretreatment agent is shown in Table 1 and Table 2.

[0055] A knitted fabric printing and dyeing pretreatment solution is prepared by the following method: add 30% hydrogen peroxide, sodium hydroxide, low-temperature hydrogen peroxide activator, and compound fiber positive charge protector to water, and stir evenly to obtain the pretreatment solution.

Embodiment 2-3

[0057] A kind of knitted fabric printing and dyeing pretreatment liquid, the raw material ratio of compound fiber positive charge protecting agent in embodiment 2-3 and embodiment 1 is the same,

[0058] The difference between embodiment 2-3 and embodiment 1 is that the raw material ratio of the pretreatment agent is different, and the raw material ratio of the composite fiber positive charge protecting agent in the pretreatment agent is the same, and the raw material ratio of the pretreatment agent See Table 1.

Abstract

The invention relates to a knitted fabric printing and dyeing pretreatment solution, a preparation method of the knitted fabric printing and dyeing pretreatment solution and a knitted fabric dyeing process and belongs to the technical field of knitted fabric dyeing. The pretreatment solution comprises water and a pretreatment agent. The pretreatment agent comprises 30%-hydrogen peroxide, sodium hydroxide, a low-temperature hydrogen peroxide activator and a compound fiber positive charge protective agent. The compound fiber positive charge protective agent comprises a non-ionic penetrating agent, ethylene diamine tetramethylene sodium phosphate, diethylenetriamine pentamethylene phosphonic acid, acrylic acid maleic acid copolymer, isomeric alcohol polyoxyethylene ether and water. Accordingto the pretreatment solution, on the basis of keeping the good bleaching effect of the pretreatment solution, the influence of the pretreatment solution on the number of positive charges on the surface of the knitted fabric is reduced, and the color rendering effect of the knitted fabric is improved. Meanwhile, in the pretreatment process of the knitted fabric, normal-temperature stacking is adopted, the operation is easy and convenient, and the cost is low; in the dyeing of the knitted fabric, only reactive dye is added, the dyed wastewater can be recycled or degraded, and the pollution of the wastewater to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of knitted fabric dyeing, more specifically, it relates to a knitted fabric printing and dyeing pretreatment liquid, a preparation method and a knitted fabric dyeing process. Background technique [0002] Knitted fabric is a fabric formed by bending yarns into loops with knitting needles and interlocking them. Knitted fabric has the characteristics of soft texture, moisture absorption and breathability, perspiration and warmth retention, and has excellent elasticity and extensibility. Clothes made of knitted fabrics are comfortable to wear, close to the body, without a sense of tightness, and can fully reflect the curves of the human body. [0003] When reactively dyeing knitted fabrics, although reactive dyes can directly dye knitted fabrics, knitted fabrics are generally negatively charged in the dye solution, and reactive dyes are also negatively charged. Due to the static electricity between reactive dy...
