Problems solved by technology

[0006] However, the above-mentioned additives all contain phosphorus, which leads to the fact that the phosphorus content of the sewage discharged from the actual production of printing and dyeing enterprises does not meet the environmental protection requirements, which greatly limits its industrial application. Therefore, it is urgent to develop a new type of phosphorus-free cold reactor pretreatment additive. and its application

Embodiment 1-5

[0042] Embodiment 1-5 A kind of novel phosphorus-free cold reactor pretreatment aid

[0043] Examples 1-5 are the components and dosage (parts by weight) of the new phosphorus-free cold reactor pretreatment additive, as shown in Table 1.

[0044] Table 1

[0045]

[0046]

[0047] The preparation method is:

[0048] S1. Mix the isomeric alcohol ether, octylphenol polyoxyethylene ether, methacryloyl ethyl betaine and sodium dodecylbenzenesulfonate in the formula amount, heat up to 50°C, and stir at a speed of 60rpm for 15- After 20 minutes, cool to room temperature 25°C to obtain an emulsion;

[0049] S2, mixing and dissolving the water, sodium acetate and cyclodextrin in the formula amount to obtain solution 1;

[0050]S3. Add the emulsion obtained in step S1 to the solution 1 in step S2, stir for 15-20min, add 1mol / L sodium hydroxide solution to adjust the pH value, then add the antibacterial agent in the formula, and continue stirring for 10-15min , filter and disc...

experiment example 1

[0063] Experimental example 1. Phosphorus content test

[0064] According to GB11893-89 D, the phosphorus content test is carried out to the novel phosphorus-free cold reactor pretreatment additive of embodiment 1-5, find that the phosphorus content of the novel phosphorus-free cold reactor pretreatment additive prepared by the embodiment of the present invention 1-5 is 0ppm. It shows that the novel phosphorus-free cold reactor pretreatment additive prepared by the invention does not contain phosphorus and meets the latest environmental protection requirements.

experiment example 2

[0065] Experimental example two, penetration

[0066] Penetration test method: test the standard canvas sheet in the working fluid (20-21°C) of the corresponding concentration of the new phosphorus-free cold reactor pretreatment additive prepared in Examples 1-5 and Comparative Examples 1-4 from the contact liquid level to the settlement For the time taken to the bottom, the working fluid is 3g / L new phosphorus-free cold reactor pretreatment additive, 60g / L caustic soda+6g / L new phosphorus-free cold reactor pretreatment additive; the results are shown in Table 2.

[0067] Table 2

[0068]

[0069] As can be seen from the above table, according to Examples 1-5, the novel phosphorus-free cold reactor pretreatment aid prepared by the present invention has good penetration under alkali-free or alkali-free environments; Ratio 1 found that when the weight ratio of isomeric alcohol ether, octylphenol polyoxyethylene ether and methacryloyl ethyl betaine was 9:9:4, the penetration ...

Abstract

The invention discloses a novel phosphorus-free cold pad-batch pretreatment auxiliary agent and application thereof. The novel phosphorus-free cold pad-batch pretreatment auxiliary agent comprises thefollowing components in parts by weight: 12-22 parts of heterogeneous alcohol ether, 15-20 parts of octylphenol polyoxyethylene ether, 10-15 parts of sodium acetate, 5-10 parts of methacryloyl ethylbetaine, 1-3 parts of cyclodextrine, 2.5-5 parts of alkyl glycoside, 5-10 parts of sodium dodecyl benzene sulfonate, 3-8 parts of a pH regulator, 1-3 parts of an antibacterial agent and 10-25 parts ofwater. The invention also provides the application of the novel phosphorus-free cold pad-batch pretreatment auxiliary agent in fabric cold pad-batch pretreatment. The novel phosphorus-free cold pad-batch pretreatment auxiliary agent is good in permeability and stable in strong alkali resistance and oxidant resistance, can endow a treated fabric with good whiteness, capillary effect and desizing effect, meanwhile, damage to the overall strength of the treated fabric is small, and the cloth cover effect of the fabric treated by phosphorus-containing products can be achieved.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a novel phosphorus-free cold-stack pretreatment auxiliary agent for all cotton and its blended fabrics and an application thereof. Background technique [0002] Cold stacking process refers to a processing method in which fabrics are padded with working fluid at normal temperature (25-35°C), then stacked at normal temperature for 18-24 hours or more, and finally washed with high-efficiency water. Through long-term stacking, impurities such as cottonseed hulls, pectin, and cotton wax on the fibers are removed, so that the fabric can achieve the required wool effect and whiteness, and endow the fabric with the advantages of soft hand feeling and good dimensional stability. At the same time, this The process also has the advantages of simple equipment, less floor space, wide product adaptability, energy saving, cost reduction, etc., and has great development potent...
