Problems solved by technology

[0002] During the post-finishing process of textiles, it is necessary to use a softener to soften and fluff the fabric to improve the touch and appearance of the fabric. In the prior art, amino silicone oil is used as a softener to soften and fluff the fabric. The fabric has serious yellowing, poor moisture absorption and air permeability, and poor fluffy feeling. Therefore, the prior art has the problems and deficiencies of serious yellowing, poor moisture absorption and air permeability, and poor fluffy feeling

Abstract

The invention discloses a preparation method of a polyoxy alkyl epoxy modified amino silicon oil softening agent. The preparation method of the polyoxy alkyl epoxy modified amino silicon oil softening agent comprises a formula and a preparation method. According to the invention, a copolymer of an amino silane coupling agent and octamethylcyclotetrasiloxane is modified, and an epoxy group of active polyoxy alkyl epoxy group ether is grafted on a side chain of amino silane so as to obtain the polyoxy alkyl epoxy modified amino silicon oil softening agent; and therefore, the yellowing, the moisture adsorption permeability and fluffy sense of tided fabrics are improved; the reaction activity, the compatibility and the easily emulsifying performance of the softening agent are improved; and the defects of serious yellowing, poor moisture adsorption permeability and poor fluffy sense in the prior art are overcome. The fabrics are tidied by using the prepared softening agent, so that the tided fabrics fulfill the aims of reducing the yellowing and improving the moisture adsorption permeability and the fluffy sense.

Description

technical field [0001] The invention relates to a preparation method of a fabric softener. Specifically, it refers to a preparation method of a polyoxyalkylene epoxy-modified amino silicone oil softener used for soft and fluffy finishing of textile articles. Background technique [0002] During the post-finishing process of textiles, it is necessary to use a softener to soften and fluff the fabric to improve the touch and appearance of the fabric. In the prior art, amino silicone oil is used as a softener to soften and fluff the fabric. The fabric has severe yellowing, poor moisture absorption and air permeability, and poor fluffy feeling. Therefore, the prior art has the problems and deficiencies of serious yellowing, poor moisture absorption and air permeability, and poor fluffy feeling. Contents of the invention [0003] Aiming at the problems and deficiencies in the above-mentioned prior art, the present invention adopts the method of modifying the copolymer of aminos...
