Problems solved by technology

[0004] Most of the wet rubbing fastness enhancers on the market are cationic, and cannot be bathed with anionic additives in application
The wet rubbing fastness improving agent has the following defects: first, the wet rubbing fastness improving agent has a higher production cost and a larger dosage, which has an impact on the shade and physical and mechanical properties of the fabric
Second, the synthetic raw materials of some wet rubbing fastness improving agents are highly toxic, and there are potential safety hazards in production, which do not meet environmental protection requirements
[0005] There are many reasons for the low wet rubbing fastness of fabrics, but one of the important factors is the structural characteristics of the fabric itself. Its surface is porous, hairy and rough. During the friction process, the friction coefficient between the fabric and the friction body is large, resulting in dye shedding

Embodiment 1

[0026] The preparation and application of the ecological copper wet rubbing fastness improving agent of present embodiment 1 may further comprise the steps:

[0027] (1) Weigh 200mL of 0.05mol / L sodium dodecylsulfonate into a four-neck flask, add 17.6gL-ascorbic acid and stir thoroughly (stirring speed 500 rpm) and raise the temperature to 80°C, measure 0.5mol / L Put 200mL of copper sulfate pentahydrate in a separatory funnel, add all drops at a rate of 60 drops per minute at 80°C and continue to stir for 3 hours. After cooling down, 7g of reddish-brown copper ultrafine powder is obtained. All drugs in this reaction are analyzed Pure, the water used is distilled water;

[0028] (2) Grind the reddish-brown copper ultrafine powder collected in step (1), wash with distilled water twice, and then dry in an oven at 85°C for 2 hours;

[0029] (3) Mix 1g of reddish-brown copper ultrafine powder dried in step (2) with 10g of butyl acrylate (BA), 10g of methyl methacrylate (MMA) and 0....

Embodiment 2

[0032] The preparation and application of the ecological copper wet rubbing fastness improving agent of present embodiment 2 may further comprise the steps:

[0033] (1) Weigh 100mL of 0.05mol / L sodium dodecylsulfonate into a four-neck flask, add 8.8gVc and stir thoroughly (stirring speed 500 rpm) and heat up to 80°C, measure 0.5mol / L pentahydrate Copper sulfate 100mL was placed in a separatory funnel, and the rate of 60 drops per minute at 70°C was all added dropwise, and then the stirring reaction was continued for 3 hours. After cooling down, 3g of reddish-brown copper nanometer powder was obtained. All drugs in this reaction were analytically pure , the water used is distilled water;

[0034] (2) Grind the reddish-brown copper nanometer ultrafine powder collected in step (1), wash with distilled water twice, and then dry in an oven at 85°C for 2 hours;

[0035] (3) Mix 3g of reddish-brown copper ultrafine powder dried in step (2) with 10g of butyl acrylate (BA), 10g of me...

Abstract

The invention relates to a preparation method and the application of an ecological copper wet rubbing fastness improver. The method comprises the following steps: (1) preparing copper superfine powder modified by C12 alkyl sulfonate; (2) grinding and drying the copper nano superfine powder until the weight is constant; (3) uniformly mixing the dried copper superfine powder with butyl acrylate, methyl methacrylate and emulsifier n-hexadecane, adding a sodium dodecyl benzene sulfonate emulsifier water solution, uniformly stirring, and then performing ultrasonic dispersion in a water bath with the temperature of 0-4 DEG C for 200s to obtain a corresponding emulsion; (4) putting the emulsion into a four-neck flask, raising the temperature to 70 DEG C, adding a potassium persulfate initiator, and then reacting for 5-6 hours to obtain the ecological copper micro-capsule type wet rubbing fastness improver. The wearability of reactive dyeing fabric is improved, and the method has the characteristics that the method is simple, the cost is low, the time input and the human input are low, synthetic raw materials are low in toxicity, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a preparation method and application of a wet rubbing fastness improving agent containing copper particles. Background technique [0002] During the wearing and use of dyed textiles or clothing, some dyes that are not firmly bonded to the fiber will fall off in contact with external objects, resulting in changes in the color of the dyed product, affecting the wearability of the fabric, and causing textile fastness. reduce. Especially for dark fabrics, the wet rubbing fastness is low. With the improvement of living standards, consumers' requirements for the quality of textiles are also constantly increasing. AATCC, ISO and national standards all stipulate that the wet rubbing fastness of ordinary dyed fabrics is qualified at grades 2 to 3, and foreign customers often require wet rubbing fastnesses to reach grade 3 or even higher. At present, the wet rubbing fastness of general dark-colored dyes is usually around level 2, and ...
