After colouring procedure, fabric has unfixed dyestuff externally and also if it comes to be final goods, it causes colour migration when it is wet or throughout washing. The dye fixing agent is to be put on coloured material to take care of the unfixed dyestuff on fabric. It boosts wet colour fastness as well as material high quality

Textile auxiliaries are great chemical items in the textile printing and dyeing fabric applications. Dyeing auxiliaries is an essential sort of textile printing and textile auxiliaries, typically according to the classification of dyes, to called various types of dyeing agents. Textile auxiliaries are generally included accessory for cotton, auxiliaries for polyester, accessories for wool and also nylon, accessories for acrylic etc.

Textile Finishing Agent consists of levelling and dispersing agents, dealing with agents, spreading representative. Textile dyeing auxiliary are vital to enhance the value-added of fabrics, they can also make the textile a lot more contemporary, useful, as well as high-grade. To some expand, dyeing auxiliary’s quality impacts directly the fabric quality. The Dye-Fixing-Agent is to be put on Fabric to repair the unfixed dyestuff on fabric. It enhances Wet colour fastness as well as textile quality.

There are 2 types of dye-fixing agent

1.Reactive dye-fixing representative

The reactive fixing agent is usually introduced reactive group in the fixing agent particles, the generally utilized reactive team below is the epoxy group. This dye-fixing agent will certainly integrate some teams in fibre dye particles and develop covalent bond, which is practical to the fastness. The generally utilized reactive dye-fixing representative is as adheres to:

1.The reactive cationic softeners type taking care of the agent is typically produced by the response of diethylenediamine, dicyandiamide and also the epichlorohydrin (the introduction of epoxy group). It cannot just enhance the colour fastness of straight dyes and acid dyes, but does not change the colour.

2.Polyether reactive, dealing with agent, is a kind of non-ionic polyether dealing with agent generated by the reaction of polyester as well as epichlorrohydrin. This representative has a specific solubility in water.

3.Qatarized reactive fixing agent, is typically produced by the response of diethylenerriamine, epichlorohydrin and trimethylamine. It is commonly used as fixing representative, but the colour fastness is not great. Due to the fact that of its cationic group as well as crosslinking with fiber, it can make cellulose fiber modified

2.Non-reactive dye-fixing representative

The fixing concept is creating movie on the surface of the fiber and closing water soluble teams. It's mainly split right into cationic fixing agent and also material kind dealing with an agent.

(1)By incorporating the cationic and also the anionic team in the dye particle, it will certainly create into ionic bond as well as close water-soluble teams, hence the cationic dye-fixing representative will improve damp fastness of the material. The cationic dye-fixing representative can be divided into:

1.Cationic surface area activity fixing representative: many of the surfactant has the dye-fixing result in varying levels. This kind of dye-fixing agent consist of Cetyl pyridinium chloride as well as spamming type cationic surface active representative.

2.Non-surface-active quaternary ammonium salt, is a king of dye-fixing representative neither belongs to resin neither surfactant, which generally consists of two or more than 2 quaternary amines, which belongs to the polyamine by-products. This kind of fastness will improve the washing fastness as well as the strength of direct colour.

The dyeing Fixing Agent is to be used to dye fabric to deal with the unfixed dyestuff on fabric. It boosts wet shade fastness and also fabric quality. TEX-AUX CHEMICALS offer high quality dye fixing agents at competitive prices. Dye fixing agents one of the important in textile dyeing and printing industry, which used for improves the colour fastness of direct and reactive dyes. Visit us for more details.
