Breakthrough New Reactive Black Dye Has Been Developed Successfully.

Huntsman textile dyeing and finishing company (Huntsman Textile Effects) has successfully developed a breakthrough new reactive black dye, which contains no harmful substances - PCA, and can help textile mills to save water and reduce energy consumption.

this dyestuff It is an extension product of Huntsman Avitera SE dye, new. Avitera The black dyestuff has been verified by the testing body that it does not contain banned aromatic amine substances such as PCA.

The dye also accords with the restrictions on the harmful substances in textile production and processing, including Oeko-Tex, bluesign, zero discharge of harmful chemicals (ZDHC), and the more stringent specifications of the world famous brand's restricted substances list (RSL).

The dye has the characteristics of low temperature dyeing and fast washing. It can save more than 50% of dyeing water and energy and reduce carbon dioxide (CO2) emissions by more than 50%. dyeing The design (dyeing bath ratio is 6:1 or lower), its dyeing and elution process temperature is not more than 60 degrees, so compared with the traditional reactive black dye, it can effectively shorten the dyeing time and improve production efficiency.

The new reactive black dye has good wet fastness and can reduce the change of color drop for the end users. The dye can improve the fastness and light fastness of the fabric, and can also be applied to high performance dyeing of medium and dark colors.

The world's first successful application of reactive dyes on cotton knitted fabric surface dyeing, and manufacturing fashion jeans clothing washing effect of T- shirt, also has the advantages of low carbon and environmental protection production.

In this study, reactive dyes were applied to surface dyeing of cotton knitted fabrics. The surface dyed knitted fabric can be used as a fashion for jeans washing. The amount of dyes and chemical auxiliaries less than half of conventional dyeing methods can significantly reduce pollution and environmental protection.

Because the liquid quantity is low, the baking energy is saved. This technology reduces the conventional dyeing time from eight hours to a few minutes, and is a low carbon emission dyeing technology. This technology also has the advantages of complete chromatography and bright color.

Characteristics and advantages:

1. can produce pure cotton knitted T- shirt with fashionable washing effect.

2. environmental protection: the dye dosage is less than half of the conventional dyeing method.

3. low carbon: dyeing processing time reduced from 4-8 hours to a few minutes.

4. chromatography is complete and bright.

Application:

The invention can provide the processing technology of the T- shirt with jeans washing style for the cotton knitted industry. The annual output of cotton knitted fabric in the world is more than 8 million tons, and the annual output of cotton T- shirts is not less than 20 billion, so this technology has broad application prospects. If applied, it can save a lot of energy and reduce carbon emissions.
