Problems solved by technology

The original dyes cannot meet the light fastness requirements of outdoor products
[0004] At present, the disperse dyes with better relative light fastness on the market are high-temperature type above 230°C (destructive to fabrics), and the color is light and the color is poor.
Can not meet product requirements

Embodiment 1

[0035] Take 41g of Disperse Red 86 ink, 9g of Disperse Red 60 ink, add 30g of methanol and stir and mix to prepare red disperse dye printing paste; measure the ink viscosity with 2# Cai En cup at 25°C (±1°C).

[0036] Take 5g of the red printing paste prepared above, first scrape and print it on a special transfer paper with a color scraper, and then use a high-temperature pressing machine to perform thermal transfer printing according to the 220°C, 25s process operation method, and the fabric chooses a polyester fabric 70g / m 2 Slub cloth, finally obtain red polyester fiber printed fabric, measure the color depth L value of the printed fabric with an instrument, and carry out the 200H light fastness test on the obtained fabric at the same time, see the test results of the light color fastness and color depth L value of the product Table 1.

Embodiment 2

[0038] Take 34g of disperse red 86 ink, 16g of disperse red 60 ink, add 30g of isobutanol and stir and mix to make red disperse dye printing paste; measure the ink with 2# Caien cup at 25°C (±1°C) viscosity.

[0039] Take 5g of the prepared red printing paste, scrape and print it on a special transfer paper with a squeegee first, and then use a high-temperature pressing machine to carry out thermal transfer printing according to the 220°C, 25s process operation method, and the fabric is polyester fabric 70g / m 2 The slub cloth finally obtained red polyester fiber printed fabric, measured the color depth L value of the printed fabric, and carried out the 200H light fastness test of the obtained fabric, and the light fastness and color depth test results of the product are shown in Table 1.

Embodiment 3

[0041] Weigh 7.5g of Disperse Yellow 64 ink, add 42.5g of Disperse Yellow 163 ink, add 25g of isobutanol into a beaker and stir evenly to prepare yellow disperse dye printing paste; Cup the ink viscosity.

[0042] Then scrape and print the yellow printing paste prepared above onto a special transfer paper with a squeegee, and then use a high-temperature pressing machine to carry out thermal transfer printing according to the 220°C, 25s process operation method, and finally obtain a yellow polyester fiber printed fabric. , measure the color depth L value of the printed fabric, and carry out the 200H light fastness test to the obtained fabric, and the light fastness and color depth test results of the product are shown in Table 1.

Abstract

The invention discloses a disperse dye combination product in red, yellow and blue colors, wherein a red composition is prepared by mixing 45-83% of disperse red I and 17-55% of disperse red II; a yellow composition is prepared by mixing 15-45% of disperse yellow I and 55-85% of disperse yellow II; a blue composition is prepared by mixing 35-42% of disperse blue I, 17-25% of disperse blue II and 35-42% of disperse blue III. The dye composition is blended with additives, such as a diluent and the like, to produce a commercial disperse dye. The commercial disperse dye is suitable for high-temperature heat-transfer printing of polyester fibers, has moderated color development temperature and bright color gloss, is high in brightness, has environment-friendly printing technology and can reachultrahigh-sunlight-resistant demand in light fastness.

Description

technical field [0001] The invention relates to the technical field of disperse dye printing and dyeing, in particular to an environment-friendly high solar heat transfer red, yellow and blue disperse dye mixture composed of red, yellow and blue three-primary color two-component or three-component compounds and its polymer Application on polyester fiber. Background technique [0002] Disperse dyes have a broad market because of their small molecular weight, simple structure, complete color spectrum, bright colors and excellent performance. Transfer printing is to print the dye pattern on the printing paper by passing the disperse dye through a special printing plate (gravure), and then transfer the pattern on the printing paper to the required fabric (polyester) by using the high temperature sublimation principle of the non-dispersible dye. superior. With the demand of the market, the light fastness requirements of outdoor leisure products are increased. [0003] At prese...
