What Are the Requirements of Finishing Agent for Finishing Process?

What Are the Requirements of Finishing Agent for Finishing Process?

Time:   Click: 128

The finishing process is mainly related to modifying the fibre surface (outer surface and inner surface). In terms of the requirements for finishing agents and finishing agents that can give fabrics a new hand-feel style or a new surface visual style, these styles are also required to be maintained as long as possible. Therefore, it is best that the finishing agent can chemically bond with the cellulose molecules and will not easily fall off during bonding.


Ⅰ. The structure and function of the finishing agent


Some finishing agents have two functional groups on the molecule, one can be combined with the fibre, and the other floats on the fibre's surface to change the surface properties of the fibre. This structure is very similar to surfactants, and such finishing agents can be said to be surfactants in a broad sense.


According to the changes in the surface properties of the fibres after finishing, finishing agents and finishing processes can be divided into several categories. For example, finishing related to fibre surface wetting performance includes water-repellent finishing and oil-repellent finishing. Finishing related to fibre surface friction performance has soft, slippery, fluffy, clean, and aromatic finishing that provides other special functions. , Flame retardant finishing, antistatic finishing, etc. Not all finishing agents have this function.


Ⅱ. The performance of a finishing agent


For example, shrink-proof finishing relies on the cross-linking effect of resins; the bio-lighting finishing of cellulose does not add finishing agents to the fibres but achieves the goal by reducing the amount.


Polymer finishing agents are an essential class of finishing agents. The finishing agent has good film-forming properties. When it covers the fibre's surface, it forms a new surface and produces a new surface style.


In the molecular structure of high-performance macromolecular agents, there are various functional groups with different functions. Together with the main chain, they play different roles to achieve different touch styles and become multifunctional finishing agents.
