Problems solved by technology

By comparing the two, it can be seen that the ammonia value of the existing main chain block amino silicone oil is generally not more than 0.3mmol / g, and the ammonia value is low; the amino group is introduced by the reaction of difunctional polyetheramine and epoxy-terminated (polyether) silicone oil. , the range of ammonia value is generally 0.1 ~ 0.3mmol / g, the adjustable space of ammonia value is small; the amino group is located on the main chain of the macromolecule, the steric hindrance is relatively large, and the directional adsorption effect on the fiber surface is not good
Thereby, these problems limit the further promotion of existing main chain block amino silicone oil softener performance to a certain extent
For this reason, the present invention provides a main chain block amino silicone oil containing tertiary amino groups in the side chain, which solves the problem of poor directional adsorption effect of the existing main chain block amino silicone oil, low ammonia value and small adjustment space for the ammonia value, and the amino acid Located on the main chain of the macromolecule, the steric hindrance is relatively large, which limits the further improvement of the handle of the finished fabric

Abstract

The invention discloses a preparation method and application of main chain embedded terminal amino silicon oil with a side chain containing a tertiary amino group. The preparation method comprises thestep: with a side tertiary amino group-containing secondary amine end-capping linear comb-shaped epoxy polyamine compound and end epoxy (polyether) silicone oil as raw materials and an organic solvent as a reaction medium, performing an aminolysis ring-opening reaction of the epoxy group to prepare the main chain embedded terminal amino silicon oil with the side chain containing the tertiary amino group. Then a novel embedded terminal amino silicon oil softening agent for fabric softening and finishing is obtained by adjusting the pH to 5 to 6 with glacial acetic acid, and adding an environment-friendly emulsifier for mechanical emulsification. Compared with the existing main chain embedded terminal amino silicon oil softening agent, the novel embedded terminal amino silicon oil softeningagent has more excellent hand feeling.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a preparation method and application of a main chain block amino silicone oil containing tertiary amino groups in the side chain. Background technique [0002] Amino silicone oil is a silicone high-molecular polymer containing amino groups on the side groups of macromolecules. After it is mechanically emulsified into amino silicone oil emulsion with an emulsifier, it can be widely used in the finishing of textiles such as cotton, silk, wool and polyester. The fabric has rich hand feeling such as soft, smooth, fluffy and elastic, and has been widely accepted by people. However, because the macromolecular chain of amino silicone oil usually has no hydrophilic groups, the hydrophilicity of the finished fabric is poor, which makes it difficult to repair and dye, and the wearing comfort is not good. At the same time, the hydrophobicity of its macromolecules also leads to ...
