Abstract

The invention discloses a preparation method of an organosilicone multicopolymer fabric softener. The preparation method comprises the following steps: firstly reacting an epoxy-terminated end-capping agent with polyether amine to obtain a polyether modified end-capping agent; adding octamethyl cyclotetrasiloxane, a silane coupling agent and a catalyst to react to obtain an organosilicone multicopolymer; finally adding isopropanol and water to the organosilicone multicopolymer to the required solid content, heating and stirring. According to the preparation method of the organosilicone multicopolymer fabric softener provided by the invention, the problems that a fabric finished by amino-modified silicone oil is easily yellowed and the existing segmented ternary silicone oil softener cannot both have flexibility and durability are solved, and the finished fabric is rich and full in hand feeling, and has excellent flexibility; the good softening effect can be achieved by using low-cost raw materials and a synthetic process, so that the very high additional value is given to the fabric, and the considerable economic benefit can be obtained by investment companies.

Description

technical field [0001] The invention belongs to the technical field of polymer synthesis, and in particular relates to a preparation method of an organosilicon multiple copolymer fabric softener. Background technique [0002] In the process of textile processing, the fabric needs to go through the action of various additives and dyes and mechanical force under hot and humid conditions, which changes the fabric structure and fiber morphology to a certain extent. For natural fibers, the oil wax in them The texture is destroyed, and for synthetic fibers, the surface oil is removed, causing the fabric to feel hard and rough. Therefore, softeners are needed to reduce the friction coefficient of the fiber surface and give the fabric a long-lasting smooth and soft feel. [0003] Most softener varieties are surfactants. Anionic and nonionic softeners are mainly used for cellulose fibers, cationic softeners are suitable for both natural fibers and synthetic fibers, and amphoteric s...
