Technical Field

The invention belongs to the field of textiles, and particularly relates to a preparation method of a mothproof and mildewproof finishing agent.

Background

Fabric finishing is the application of a finishing agent to a fabric which alters the surface properties of the fabric to impart specific functions to the fabric. For example, hydrophobic and oleophobic finishes are achieved by treating the fabric with a finish having a low surface tension to modify the surface characteristics of the fibers so that the fabric surface is not readily wetted and spread by water or oil. The antifouling finish and the easy-to-remove finish are processing technologies which change the surface performance or the surface state of the fiber, so that the fabric is not easy to be stained with the dirt under the wearing and using conditions, or the stained dirt is easy to wash and is not stained. Usually for textile production or later maintenance.

The fabric finishing agent can endow the textile with various special functions and styles, such as softness, crease resistance, shrinkproof, waterproof, antibacterial, antistatic, flame retardant and the like.

The conventional finishing agent usually mixes a plurality of solutions with different functions, and in order to avoid the mutual influence between the solutions, an additional process is usually required for modification, so that the processing process is complicated, the time required for processing is long, and the production cost is high.
