Industry information

　　(1) Compared with the ionic softener, it has poor adsorption capacity on the fiber, and has no softening effect on synthetic fiber, but can smooth it. It is mainly used for the finishing of cellulose fibers, especially bleaching and light colored fabrics.

　　(2) It can be used as a bath softener to prevent wrinkles and abrasions. For example, the bath softener alveron GBV of textil color company is composed of a variety of lactones, ester based nonionic surfactants and natural liver cirrhosis agents. There are also some nonionic softeners in China.

　　(3) Nonionic softeners have good compatibility with anionic and cationic softeners, and have good stability to electrolytes. In order to improve the softness of nonionic softeners to fabrics, moderate weak cationic softeners are often added in practical production without changing nonionic properties; In order to improve the smoothness and dispersion of cationic softeners, non-ionic softeners are often added into the formulation; as anionic softeners, when the dispersibility of sulfonated succinate in water is not ideal, the polyol type non-ionic softeners are often added to improve emulsification and dispersion without reducing their own softness.

　　(4) The solubility of nonionic softeners, especially ether based or ester based products, will decrease with the increase of temperature. The temperature at the beginning of turbidity is called cloud point, which is related to the gradual disconnection of ether group, ester group and hydrogen bond formed with water molecules with the increase of temperature. This is an important feature of non-ionic active agents. Therefore, it is beneficial to select products with higher cloud point in practical application.

　　(5) Nonionic softeners, like anionic softeners, have no yellowing problem in fabric finishing, but water absorption is not as good as anionic softeners.

　　At present, there are many kinds of non-ionic softeners in the domestic market. The product is ginsoftn-100, which is a special non-ionic softener. It can not only be used as resin softener, but also be used for finishing and softening of cotton, synthetic fiber and blended fabric. By comparison, it is better than ordinary weak cationic softener, and the effect is better when compounded with anionic smoothing agent.
