Introduction to popular science on the role of softener agent




1. The role of softener agent

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 agent.

In order to achieve the above effects, softener agent 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 softener agent that can cross-link with some reactive groups on the fiber to achieve the purpose of washing durability.

2. Requirements of softener agent

1. Under various soft processing conditions, the working fluid should be very stable.

2. Does not reduce the whiteness and color fastness of fibers or fabrics.

3. 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.

4. If the softener agent is emulsion, its emulsion stability is better.

5. According to different processing requirements, it can have proper water absorption or water repellency, anti-static properties and other properties (should be selected according to the different requirements of the fabric). It is resistant to washing or dry cleaning.

6. There is no adverse effect after human skin contact.

Due to the wide variety of textiles, different fibers used, different fabric specifications, different fabric uses, and different finishing requirements, the selection of softener 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 agent is always limited. To obtain multiple performance effects, two or more softeners can be used in combination (or compounded into a new softener agent product). ). For example, the combined application of silicone softener and long-chain aliphatic softener agent can achieve better effects of soft, plump and slippery touch. It can also combine the application of softener with mechanical softening and often obtain good results. effect.
