The role of fabric softening agents:
1. Supplement the natural oils lost by natural fibers in scouring and bleaching processes, making the hand feel more ideal.
2. Attach to natural fiber or synthetic fiber to improve smoothness and strength, and improve hand feeling.
3. Improve the wearability of the fabric through some characteristics of the softener.
In order to achieve the above effects, softeners are generally grease-like smoothness and hand-feel substances. Adhering to the fiber surface can reduce the frictional resistance between the fibers and make the fibers lubricate and soft. There are also some softeners that can cross-link with some reactive groups on the fiber to achieve the purpose of washing durability.
