What's Vat Dyes

Vat dyes are a class of dyes that can be reduced to a soluble state under certain conditions and are commonly used to dye natural and synthetic fibers. They convert the pigment part of the dye into a colorless state through a reduction reaction, and then re-oxidize during the dyeing process to form a colored compound.


Vat dyes are high-grade dyes with excellent fastness. There are many varieties of these dyes, with a complete color spectrum and bright colors. They are mainly used for dyeing textiles. In addition to cotton fibers, they can also be used for viscose fibers, polyester, etc.

Tiankun vat dye solutions focus on providing excellent color fastness and color stability for the textile industry. Through innovative vat processes and environmentally friendly technologies, we ensure that every dyeing shows a lasting and bright color effect.

Vat Indigo 94% is a high-purity indigo dye specifically designed for denim dyeing, with excellent color fastness and dyeing uniformity. It can produce a deep classic blue tone, ideal for creating premium denim products.

At HANGZHOU TIANKUN CHEM CO., LTD., we pride ourselves on delivering superior dye solutions through stable quality, robust R&D, rich export experience, and exceptional local services. Here's what sets us apart:

During the production process of vat dyes, due to fluctuations in raw materials or slight deviations in the operating process, different batches of dyes may have different dyeing effects. In order to reduce batch differences, Tiankun strengthened raw material quality control, optimized production processes, and introduced automated detection systems. Through these measures, the quality of each batch of products can be ensured to be consistent.

In the market, the supply of certain specific colors of vat dyes (such as Yellow 2) is unstable. This may be due to the global shortage of raw materials and the limited production capacity of production plants.

TIANKUN ensures stable supply by increasing inventory reserves of key raw materials or producing alternative dyes.

The production process of vat dyes is complex and requires multiple steps such as reduction and oxidation. Compared with direct dyes, the production cost is higher. Its raw materials are mostly imported or rare substances, resulting in a higher market price.

Tiankun can reduce the production cost of vat dyes through technological innovation and process improvement.

There are many different vat dye standards in the global market, and different countries and regions have different requirements for the quality and performance of dyes. This diversity of standards makes it difficult for companies to accurately understand the specific standards of the target market when entering new markets or developing international markets, increasing the difficulty of compliance and adaptation.
