Technical Field

The invention relates to the technical field of textile treating agents, in particular to a non-ionic emulsifying wetting agent used in a textile pretreatment process and a preparation method thereof.

Background

The silicone oil is used as an important component of the fabric and sewing thread treating agent thereof, and plays an important role in realizing the function of the treating agent. However, in the preparation process of the treating agent, the silicone oil has high viscosity, so that the silicone oil is difficult to uniformly disperse in an aqueous solution to form a uniform emulsion, and the compatibility with other components in the treating agent is poor. Therefore, when the treating agent is used for treating fabrics or fabric sewing threads, the wetting, penetration and diffusion properties of the treating agent are poor, and oily substances such as silicone oil are easy to stay on the surfaces of the fabrics or the sewing threads to form silicon spots, so that the fabrics and the sewing threads are poor in quality and even become waste products.

In the prior art, a single surfactant and an emulsifier are added into a fabric treating agent to emulsify and disperse oily components such as silicone oil, but the fabric treating agent has the conditions of rapid penetration, strong emulsifying and dispersing capacity, high cleaning power, low foamability, easy biodegradation, safety, no toxicity and the like as an efficient treating agent. Thus, a single surfactant does not suffice, and is usually a multi-component formulation.
