The penetrant is a compound that helps improve the affinity of dye material to fibers in the textile industry, accelerates the bonding of dye material, and reduces its solubility, playing an important role in dyeing.

The penetrant is a chemical substance used as a leveling agent, meaning it reduces negative charges on the fibers. By doing so, it allows dyes to penetrate uniformly and effectively into textiles.

With the development of the textile industry and the advancement of the fashion industry day by day, the need for compounds that assist these industries is increasing. By using penetrants, many functions can be facilitated. These compounds are used in various industries, including textiles. Buying and selling these compounds has a wide market, and you can easily purchase them even online and use them.

Properties and Characteristics of Penetrants

In the textile industry, penetrants act as catalysts. Fabric layers and dye molecules have heterogeneous characteristics, making their combination difficult. In such cases, we need a catalyst to facilitate the dyeing process on the fabric. The benefits of using penetrants include:

Guiding the dye into the fabric structure during the dyeing process in textiles

As an electrolyte for migration, absorption, and fixation of dye material to cellulose materials

Usually soluble in cold and hot water in any proportion

These compounds are compatible with direct, acid, and reactive dyes

They are stable against hard water and chemicals.

This substance leads to whiter and better water absorption in cotton fabrics and is also used as a grease remover.

The penetrant and leveling agent have a floor control feature.

Due to their high dispersibility and emulsifying properties, they prevent re-deposition of impurities such as oil, wax, pectin, and other fats present in fibers and enhance the cleansing effect.

By eliminating air bubbles between fibers, they increase water absorption and promote uniformity.

After whitening with this substance, the hydrophilic property will have an excellent increase, and a noticeable difference will be observed.

High permeability and air-releasing properties (removing air from the product)

The property of removing air from the fabric, especially in winch machines, ensures that the fabric does not remain afloat on the water surface, leading to greater uniformity.

Applications of Penetrants

Due to their high penetrability, they are used in foulard systems, thermosols, baby pads, steam pads, etc.

Due to their very high permeability, they are used in continuous processes.

They are used for washing fabrics.

They are used as wetting agents in dyeing processes.

This substance is used to penetrate dyes into fibers and as a washing agent in the tanning industry.

In bleaching and dyeing processes of bobbins and spools, they are used to remove air from bobbins and spools.

By eliminating air bubbles, increasing water absorption, and allowing dye to penetrate uniformly on the surface and inside the yarn or fabric in bobbin dyeing systems, they promote uniformity.

Especially suitable for dyeing dark shades in the same bath.

Penetrant Dosage

The dosage of these compounds is 0.1 to 0.5 grams per liter, and they are usually added to the dye bath at room temperature and then gradually used by raising the temperature to 60 degrees Celsius in several stages.
