Comprehensive specifications and application methods for DYCROSPERSE Disperse Dyes
Jagson disperse dyes can be used for dyeing and printing of polyester fibers and polyester fiber blends. In exhaust dyeing, the most important method of application is high temperature process.
Besides high temperature process Jagson disperse dye can also be used for carrier process and in continuous dying by the thermosol process. In printing fixation can be achieved depending on the sublimation properties either by HT steaming, hot air, or by pressure steaming. We have covered almost all the properties of disperse dyes in this shadecard. A lot of technical efforts have been taken to ease the implementation process of Jagson disperse dyes for the customers.
Disperse dyes can be mainly divided in 3 basic structure:
Respectively the dyes can be classified as:
| E-type | SE Type | S Type |
|---|---|---|
| Good leveling property | Good exhaustion type at medium dyeing temperature | Good for exhaustion at high dyeing temperature |
| Suitable for pale-medium shade | Good leveling property | Excellent sublimation and high stability for various finishing process |
| Suitable for carrier dyeing as well as high temperature dyeing | Good sublimation fastness | Suitable for medium-deep shade by high temperature,thermosol dyeing and printing |
| Suitable for pale-deep shade by high temperature,carrier,thermosol dyeing and printing |
Polyester fibers have excellent properties in term of
Following are the dyeing methods for polyester fiber:
Practical dyeing methods, may vary according to kind of blended fibres, various fastness and handling to be required.
The pretreatment and dyeing methods vary based on the form in which this substrate is being processed:
Pretreatment serves for removing sizes, preparations, and soil from the surface of the fiber. In case of knit and woven goods, it serves for relaxation and bulkiness.
In case of polyester-cellulose blends desizing and mercerizing must be carried out prior to scouring.
Desizing and scouring must be carried out prior to dyeing.
Bleaching is an optional step. If a higher degree of white is desired, optical bleaching agents must be used.
Heat setting is required to stabilize polyester fabric. Ensuring the piece goods retain its shape during all the stages depends on the nature and structure of the fabric.
pH needs to be maintained after all auxiliaries and dyes are added. Buffer system is used to maintain constant pH throughout the dyeing process.
Disperse colors are usually high temperature dyes. In majority of the cases it is used in powder/ granule form. The 2nd option available is paste form which is 50%-80% content concentration of the powder product. Generally luke warm water (40° -50°C) is added with stirring to complete the dispersion .
The dye batch must be controlled to pH 4.5-5 using weak acid such as acetic acid or with buffer using sodium acetate to promote the reproducibility of dyeing or to maintain the brilliance of shade.

Only selected dyes can be used in carrier dyeing because the exhaustion and build up property are rather poor. Compared to temperature dyeing covering property is also poor.

| And then Reduction clearing is done | |
Thermosol dyeing is employed as a continuous dyeing mainly in polyester/cotton blends,because of very high fixing temperature around 200*C. Dyes with high sublimation fastness are recommended for the thermosol dyeing. Liquid grade dyes are recommended for thermosol dyeing
The stages involved in thermosol dyeing are: (Dyepad dyeing). It includes Reduction clearing after dyeing and washing.
For 100% polyester following process is followed:
