A kind of polyquaternium glucose polydimethylsiloxane polyether and its preparation method and handle finishing agent

Abstract

The invention provides a polyquaternary-ammonium-based glucose polydimethyl siloxane polyether, a preparation method thereof and a hand-feeling finishing agent applying the polyquaternary-ammonium-based glucose polydimethyl siloxane polyether. The polyquaternary-ammonium-based glucose polydimethyl siloxane polyether is expressed by a general formula I. By the synthesis process line and initiator selection, the film-forming apparent state of the hand-feeling finishing agent is transformed from a liquid state or a semi-colloidal state in the current existing technology into a solid state or an elastomer solid state, so that the technical problems that 'sticky' underwear is not natural and comfortable due to excessively-oily touching feel of the original fabrics after finishing with organic silicone emulsion are thoroughly changed, so that new touching feels are endowed for the fabrics, namely, dryness and comfortableness without stickiness, dryness and comfortableness, naturalness, fineness, skin friendliness and silky smoothness; and simultaneously, the beneficial functions of instantaneous hydrophilicity, no thermal yellowing and no phenolic yellowing are endowed for cotton fiber fabrics.

Description

technical field [0001] The invention relates to the field of functional finishing agents for textiles, in particular to a polyquaternium glucose polydimethylsiloxane polyether, a preparation method thereof and a hand finishing agent. Background technique [0002] At present, the development of global textile silicone materials has gone through four stages of development: [0003] The first stage is hydroxyl silicone oil emulsion and methyl silicone oil emulsion, and its structural characteristics are as follows: [0004] Hydroxy silicone oil: Among them, n=1~100000; [0005] Methicone: Wherein m=1~100000. [0006] The second stage is amino silicone oil emulsion, its structural characteristics are as follows: [0007] [0008] Among them: m=1~10000; n=1~50; R1=-C 3 h 6 NH 2 ,-C 3 h 6 NHC 2 h 4 NH 2 . [0009] The third stage is polyether silicone oil and polyether modified amino silicone oil, whose structural characteristics are as follows: [0010] Polyet...

AI Technical Summary

Problems solved by technology

[0025] ①From the first generation to the fourth generation of silicone oil materials, the tactile function endowed to the fabric is mainly the chain link of polydimethylsiloxane polymer Fluffy, soft, smooth and other tactile functions can be realized by controlling the molecular weight of polydimethylsiloxane chains. However, this chain chain polymer has no ionicity. By introducing amine cationic groups, the adsorption capacity of the polymer can be increased. , change its directional adsorption behavior, improve the tactile function, polydimethylsiloxane This polymer has no hydrophilicity, no thermal yellowing, no phenolic yellowing

[0026] ②The introduction of polyether and polyether-modified amine groups of the third-generation silicone oil, compared with the second-generation amino silicone oil, the tactile function does not improve, but decreases, and only increases the hydrophilicity of polydimethylsiloxane , the main reason is that the molecular weight of the third-generation silicone oil is very small, the overall molecular weight is about 5,000-20,000, and the chain link of polydimethylsiloxane The molecular weight is about 370-7000, and at the same time, the film-forming properties of polydimethylsiloxane chains are destroyed due to the introduction of polyether

[0036] Therefore, we need a new hand finishing agent to solve the technical problem that the currently existing finishing fabric has an obvious "oily" touch
