The product principles of deepening agents （blooming agent） mainly achieve the deepening effect on fabrics and other materials through physical and chemical actions.

The following is a specific introduction:

 

Physical Action Principles

Regulation of Light Absorption and Reflection

Reducing the Reflectance:

The deepening agent can form a uniform film on the surface of the fabric. This film can change the way light is reflected on the fabric surface, reducing the specular reflection of light and allowing more light to enter the interior of the fabric and be absorbed by the fibers. For example, some deepening agents containing special optical particles can scatter light, making the light reflect and absorb multiple times inside the fabric, thus reducing the intensity of the reflected light and making the fabric appear darker in color.

Enhancing the Absorption Capacity:

Some deepening agents have a special molecular structure that can absorb light of specific wavelengths. This absorbed light might have been reflected originally, making the fabric's color lighter. After the deepening agent absorbs this light, it increases the overall light absorption of the fabric, thereby improving the depth and saturation of the color.
Improving the Surface Properties of Fibers

Filling the Fiber Gaps:

There are many tiny gaps and pores between fabric fibers. When light propagates in these gaps, it will be scattered and reflected, resulting in the loss of some light and affecting the depth of the color. The deepening agent can penetrate into the fiber gaps and fill these tiny voids, making the fiber surface smoother and flatter, reducing the scattering of light between the fibers, and allowing more light to be absorbed by the fibers, thus achieving the deepening effect.

Increasing the Fiber Roughness:

Contrary to the above principle, some deepening agents will appropriately increase the roughness of the fiber surface. In this way, more diffuse reflection of light can occur on the fiber surface, extending the propagation path of light on the fiber surface and giving the light more opportunities to be absorbed by the fibers, thereby enhancing the depth of the color.

 

Chemical Action Principles

Chemical Reactions with Fibers

Forming Chemical Bonds:

Some deepening agent (blooming agent) molecules contain reactive groups that can chemically react with fiber molecules. For example, some deepening agents containing hydroxyl groups, amino groups, etc., under certain conditions (such as specific temperature, pH value, etc.), can chemically react with the hydroxyl groups in cellulose fibers to form covalent bonds. The formation of these chemical bonds makes the deepening agent closely combine with the fibers, increasing the attachment amount and stability of the deepening agent on the fibers, thereby enhancing the ability to absorb and scatter light and achieving the deepening purpose.

Changing the Fiber Structure:

Some deepening agents(blooming agent) can also achieve the deepening effect by changing the internal structure of the fibers. For example, some deepening agents can make the arrangement of fiber molecular chains more regular, or change the crystallinity of the fibers, thus altering the light absorption and scattering characteristics of the fibers and making the fabric color darker.

 

Interaction with Dyes

Solubilization and Dispersion of Dyes:

During the dyeing process, the deepening agent can play a role in solubilizing and dispersing the dyes, enabling the dyes to disperse more evenly in the dye liquor and improving the solubility of the dyes. As a result, the dyes can better adsorb on the fiber surface and penetrate uniformly into the interior of the fibers. This can increase the adsorption amount of the dyes on the fibers and the uniformity of their distribution, making the color more full and deep.

Changing the Aggregation State of Dye Molecules:

The deepening agent can also interact with the dye molecules and change the aggregation state of the dye molecules on the fibers. For example, the deepening agent may promote the dye molecules to form an aggregation form that is more conducive to light absorption, or prevent the dye molecules from forming large particle aggregates that are not conducive to the color depth, thereby improving the light absorption efficiency of the dyes and achieving the deepening effect.
