Embodiment 1

[0019] (1) Add 5g of polyethylene glycol monomethyl ether and 0.5g of turpentine to 10g of polyglutamic acid, heat up to 130-135°C and grind for 2 hours, then add 0.05g of nano-zinc oxide, and continue to keep warm at 130-135°C Grind for 15 minutes, cool the obtained mixture to room temperature naturally, then add the mixture into water of equal weight, mix thoroughly, send the obtained mixed solution into a spray dryer, and dry the obtained particles into micropowder through an ultrafine pulverizer to obtain modified polyglutamine acid;

[0020] (2) Add 0.5g of ultrafine penetrant and 0.5g of hydrogenated castor oil to 2g of hexamethylolmelamine hexamethyl ether, mix well, transfer to 0-5°C environment, seal and stand for 2h, and heat up to 115-120°C Heat preservation and grinding for 15 minutes, then add 1g of polyethylene oxide and 0.1g of sepiolite fiber powder, continue heat preservation and grinding at 115-120°C for 30 minutes, cool the resulting mixture to 45-50°C at a ...

Embodiment 2

[0024] (1) Add 10g of polyethylene glycol monomethyl ether and 1g of turpentine to 15g of polyglutamic acid, raise the temperature to 130-135°C and grind for 3 hours, then add 0.1g of nano-zinc oxide, and continue to grind at 130-135°C After 15 minutes, the resulting mixture was naturally cooled to room temperature, and then the mixture was added to equal weight of water and mixed thoroughly. The resulting mixed solution was sent to a spray dryer, and the dried particles were ultrafinely pulverized into fine powder to obtain modified polyglutamic acid. ;

[0025] (2) Add 1g of ultra-fine penetrant and 0.5g of hydrogenated castor oil to 3g of hexamethylolmelamine hexamethyl ether, mix well, transfer to 0-5°C environment, seal and stand for 2h, and heat up to 115-120°C to keep warm Grind for 15 minutes, then add 2g of polyethylene oxide and 0.3g of sepiolite fiber powder, continue to grind at 115-120°C for 15 minutes, and cool the resulting mixture to 45-50°C at a cooling rate o...

Embodiment 3

[0041] Utilize respectively embodiment 1, embodiment 2, comparative example 1, comparative example 2, the color fastness enhancer of comparative example 3 to prepare dyeing according to the ratio of raw materials shown in table 1, and by the same dyeing process to the same batch of system The wool-cotton blended yarn was dyed, and a control example 4 without a color fastness enhancer was set up, and the color fastness of the fabric obtained by weaving the wool-cotton blended yarn after dyeing was measured, and the results are shown in Table 2.

Abstract

The invention discloses a color fastness enhancer for dyeing of wool-cotton blended yarn and relates to the technical field of textile dyeing auxiliaries. The color fastness enhancer is prepared from raw materials in parts by weight as follows: 10-15 parts of polyglutamic acid, 5-10 parts of methoxypolyethylene glycols, 1-3 parts of hexakis(methoxymethyl)melamine, 1-3 parts of polyethylene oxide, 0.5-2 parts of turpentine oil, 0.5-2 parts of an ultramicro penetrating agent, 0.5-2 parts of hydrogenated castor oil, 0.1-0.5 parts of sepiolite fiber powder, 0.1-0.5 parts of sodium gluconate and 0.05-0.1 parts of nano-zinc oxide. The color fastness enhancer is good in water solubility and can be rapidly dissolved in an aqueous dye solution, so that adhesive force of dye molecules on wool-cotton fibers is enhanced, color fastness of wool-cotton blended fabric woven after dyeing is improved, and appearance use quality of the fabric is guaranteed.

Description

Technical field: [0001] The invention relates to the field of textile dyeing auxiliaries, in particular to a color fastness enhancer for dyeing wool-cotton blended yarn. Background technique: [0002] With the improvement of people's living standards, people's performance requirements for clothing are also getting higher and higher. In the case that the properties of single-fiber fabrics cannot meet the needs of people, blended fabrics are more and more popular. Because cotton fiber has a larger initial modulus and finer denier, while wool fiber has excellent resilience properties, wool-cotton blended fabrics have a fine, crisp, plump, and elastic feel, and can be used to develop high-end fabrics. Knitted garments meet people's demand for high-grade knitted garments. [0003] There are certain difficulties in the dyeing and finishing of wool-cotton blended yarn, especially the problems of poor color homogeneity and low color fastness of cotton fiber and wool fiber. Aiming...
