What is "Scouring agent"?

What is the Preparartion Process?

Scouring is a preparation process to prevent problems at the next process such as dyeing or finishing by eliminating hydrophobic impurities on greige fabric without deteriorating the fabric itself.
Scouring agent is required to eliminate the impurities effectively such as sizing agent or lubricating agent, stains from weaving process and abrasion stains which come from greige woven or knitted fabric.
The required property of scouring agent varies depending on materials, fabric structure, stains and applications.

[Primary impurities]
Natural substance which fiber originally has:
Pectic substance, Cotton wax, Fatty substance, Protein substance, Inorganic substance(metal), Dye composition

 
[Secondary impurities]
Adhered substance in process:
Spinning oil, Knitting oil, Needle oil, Sizing agent, Waxing agent, Rust, Dust, etc...

Mechanism of action

Scouring agent

The surfactant, the main component of the scouring agent, is composed of hydrophilic and lipophilic groups and forms surfactant micelles in the bath. 
The lipophilic group of the surfactant adsorbs to the oil attached to the fiber and exerts an emulsifying function by being incorporated into micelles.
In addition, due to the function of the hydrophilic group, the oil-incorporated micelles are dispersed stably in the bath to remove oil stains on the fibers.
