Abstract

The invention relates to a low-yellowing organic silicon softener, a preparation method and an application thereof. The schematic constitutional formula of the low-yellowing organic silicon softener provided by the invention is FORMULA, and the invention also discloses a preparation method and an application thereof. The softener provided by the invention has cheap and easily-obtained material and simple synthetic process; the fabric after processed by using the softener provided by the invention has the soft and smooth effects after the treatment of amino silicone oil, and also adds yellowing-proof capacity and fabric durability; moreover, the fabric is not easy to drop when washing.

Description

technical field [0001] The invention relates to a low-yellowing silicone softener, a preparation method and application thereof, and belongs to the technical field of textile chemicals. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection and health awareness, people's pursuit of environmental protection and pollution-free products is becoming more and more intense. The "green barriers" to textiles in the global market are becoming more and more serious, and textile trade has entered into survival competition. In the new era, the market has put forward higher requirements for the quality of textiles, especially in industries such as clothing, home textiles, tourism, and transportation, and the requirements for special textile materials are also getting higher and higher. The fabric softener made of silicone is a kind of softener with wide application, good performance and outstanding effect in textile...
