What are the requirements for softener?

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 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 softeners 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 (or compounded into a new softener product). ). 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 softener with mechanical softening and often obtain good results.
