The role of softening agent and its selection skills.

The softening agent replenishes the natural oils lost in the refining, bleaching and other processes of natural fibers, making the hand feel more ideal. Attaches to natural fibers or synthetic fibers to improve smoothness and strength, and improve hand feel. Through certain characteristics of softening agent, the wearability of fabrics can be improved. In order to achieve some of the above effects, softening agent are generally grease-like smoothness and feel substances, attached to the surface of the fiber can reduce the frictional resistance between the fibers, and make the fibers lubricate and soft. There are also some softening agent that can cross-link with some reactive groups on the fiber to achieve the purpose of washing durability.

Due to the wide variety of textiles, different fibers used, different fabric specifications, different fabric uses, and different finishing requirements, the selection of softening agent cannot be generalized. On the basis of softening mechanisms and functions of various softeners, select those that meet the requirements. Softener. In addition, the performance of each softener is always limited. To obtain multiple performance effects, two or more softeners can be used in combination. For example, the combined application of silicone softener and long-chain aliphatic softener can achieve better effects of soft, plump and slippery touch. It can also combine the application of softening agent with mechanical softening and often obtain good results. Effect.

Under various soft processing conditions, the working fluid should be very stable. Does not reduce the whiteness and color fastness of fibers or fabrics. The softened fiber or fabric is not easy to be discolored by heat, and there should be no changes in color, feel, or odor during storage. If the softening agent is emulsion, its emulsion stability is better. According to different processing requirements, it can have proper water absorption or water repellency, anti-static properties and other properties. It is resistant to washing or dry cleaning. No adverse effects after human skin contact.
