Abstract: Quaternary ammonium cationic surfactants have very important application in the papermaking industry, which is a series of important paper softening agents. In order to obtain an environment-friendly paper softening agent, a novel diester gemini quaternary ammonium salt cationic surfactant has been prepared. Dodecyldimethyl amine, epichlorohydrin and adipic acid were used as raw materials to synthesize the surfactant, and Fourier transform infrared spectroscopy was used to characterize the groups in reaction product. Moreover, the softening effect of the diester gemini quaternary ammonium salt cationic surfactant was studied in detail.

Abstract: Organosilicon compound are widely used in pulping and papermaking industry. The quality and capability of paper sheet are distinctly affected by the use of organosilicon. The application of organosilicon used as softening agent, defoamer agent, strengthening agent were introduced one by one in this paper.

Abstract: The performance of heat transfer coefficient, wicking and water vapour permeability (WVP) of cotton fabric were tested after adding amino-functional silicone softening agent in simulating process of home laundry. Meanwhile, the experiment of line drying of fabric soaked in water after spinning was designed to study the impact of soft nursing care on drying efficiency of fabric. The result showed that with the amino-functional silicone softening agent added, handle was improved obviously. With the concentration of softening agent increasing, WVP of fabric increased, while heat transfer coefficient had the opposite result. Wicking effect increased slowly at the beginning and decreased sharply later. It was found that soft nursing care improved the drying efficiency.
