Disperse Dyes

Disperse dyes are one of the largest and most widely used categories in the dye industry, and are the dedicated dyes for polyester fibers. Currently, disperse dyes are the only type of dye that can effectively dye polyester, holding an irreplaceable position in the dyeing and printing of polyester and its blended fabrics.

Product Description

They are diverse in variety and have a complete color spectrum. Based on chemical structure, they can be divided into three main categories: azo (approximately 80%), anthraquinone (approximately 15%), and heterocyclic (approximately 5%). Based on application performance, they can be divided into E type (low temperature, good leveling properties), SE type (medium temperature, balanced overall performance), and S type (high temperature, high sublimation fastness). Based on application, they can be divided into A type (acetate/nylon), D type (polyester), and P type (printing). Products are available in various forms, including powder, granules, and liquid dispersions, covering the full color spectrum of yellow, orange, red, blue, purple, and black. Small-batch trial orders and customized packaging are supported. Relying on major ports such as Qingdao Port, Tianjin Port, and Shanghai Port, exports are efficient and worry-free throughout the entire process.

Product Information

ItemDescription
Product NameDisperse Dyes
Product DefinitionDisperse dyes are a class of non-ionic dyes with relatively small molecules and no water-soluble groups. During dyeing, they must be uniformly dispersed in the dye bath with the aid of dispersing agents to dye hydrophobic fibers such as polyester. The particle size is required to be around 1μm.
AppearancePowder, granules or liquid dispersions (paste), color varies by type
Main Types (by Chemical Structure)Azo Type: Complete色谱 (yellow, orange, red, violet, blue, etc.), accounts for about 80% of disperse dyes, simple process and low cost.
Anthraquinone Type: Red, violet, blue, etc., accounts for about 15%, more complex production process and higher cost.
Heterocyclic Type: Brilliant colors, rapidly developing in recent years, accounts for about 5%.
Main Types (by Application Performance)E-type (Low Temperature) : Low sublimation fastness, good leveling properties, suitable for high-temperature high-pressure exhaustion dyeing.
SE-type (Medium Temperature) : Performance between E-type and S-type, balanced overall performance.
S-type (High Temperature) : High sublimation fastness, poor leveling properties, suitable for thermosol dyeing.
P-type: Suitable for textile printing.
Main Types (by Application Object)A-type: Suitable for dyeing acetate fibers and nylon.
D-type: Suitable for dyeing polyester.
P-type: Suitable for textile printing.
Common Varieties (Examples)Disperse Yellow, Disperse Orange, Disperse Red, Disperse Blue, Disperse Dark Blue, Disperse Turquoise Blue, Disperse Black, etc., can be blended in different proportions. Specific varieties include: Disperse Blue SE-2R, Disperse Orange 13, Disperse Red 3B, Disperse Yellow H-WF, etc..
Key CharacteristicsVery low water solubility, exists in water in a highly dispersed state; relatively small molecular weight and low polarity; no strong water-soluble groups; sublimation fastness varies by type; not alkali-resistant, decomposes under high temperature and alkaline conditions.
Main ApplicationsPolyester Fiber Dyeing (Core Application) : Dyeing and printing of polyester and its blended fabrics.
Acetate Fibers: Dyeing of diacetate and triacetate fibers.
Other Synthetic Fibers: Dyeing of nylon, spandex, acrylic, polypropylene, polyvinyl chloride, etc..
Plastic Coloring: Coloring of plastic products.
Thermal Transfer Printing: Some E-type dyes can be used for thermal transfer printing.
Packaging25kg/bag (carton or fiber drum with PE liner), 40kg/drum (fiber drum), custom packaging available
Storage ConditionsStore in cool, dry, well-ventilated warehouse; keep sealed; protect from moisture and high temperature; avoid mixing with oxidizers, acids and alkalis
Shipping RequirementsShipped as general chemicals; protect from moisture, sunlight and leakage; handle with care
Quality StandardsVarious industry standards or enterprise standards per product type (e.g., GB/T national dye standards); export can refer to Colour Index (C.I.) numbering system

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
