Problems solved by technology

However, limited by cationic properties, polyether amino silicon is only suitable for cationic and non-ionic systems; when used in anionic systems, cationic polyether amino silicon is opposite to the charge of the system, so it is easy to cause system demulsification, oil floating or separation.

Abstract

The invention discloses linear amphiprotic carboxyl-terminated polyether amino silicon oil. The linear amphiprotic carboxyl-terminated polyether amino silicon oil is prepared from a mixture prepared from amine-terminated polyether silicon oil and dicarboxylic anhydride, wherein the amine-terminated polyether silicon oil is prepared from a mixture prepared from epoxy-terminated polyether silicon oil, polyether amine and isopropanol. The invention also discloses a cross-linking amphiprotic carboxyl polyether amino silicon emulsion softening agent prepared based on the linear amphiprotic carboxyl-terminated polyether amino silicon oil and a preparation method thereof. According to the linear amphiprotic carboxyl-terminated polyether amino silicon oil, the cross-linking amphiprotic carboxyl polyether amino silicon emulsion softening agent and the preparation method of the cross-linking amphiprotic carboxyl polyether amino silicon emulsion softening agent, disclosed by the invention, cross-linking amphiprotic carboxyl polyether amino silicon oil is prepared into a silicon emulsion softening agent by using a non-ionic surfactant, and the silicon emulsion softening agent is used for fabric after-treatment, so that the soft hydrophilic performance and the hand feeling of fabric can be improved, and good elasticity and good one-bath using performance can also be given to the fabric.

Description

technical field [0001] The invention belongs to the technical field of textile finishing agents, and in particular relates to a linear amphoteric carboxyl-terminated polyether amino silicone oil, a cross-linked amphoteric carboxyl polyether amino silicone emulsion softener prepared by the same and a preparation method. Background technique [0002] Polyether amino silicon, which has multiple excellent properties of hydrophilic polyether groups and amino silicone oil, is used in the finishing of fiber fabrics, which can not only significantly improve the softness, smoothness and hand feeling of fiber fabrics, but also give the fabrics good Moisture absorption, air permeability and antistatic properties, so it has become the most popular type of soft finishing additives in recent years. However, limited by cationic properties, polyether amino silicon is only suitable for cationic and non-ionic systems; when used in anionic systems, cationic polyether amino silicon is opposite ...
