Problems solved by technology

However, highly toxic chemicals such as dimethyl sulfate are used in the preparation process, which has great limitations in practical application, especially as the environmental protection requirements of the printing and dyeing industry increase year by year, this method can no longer meet the needs of environmentally friendly production
[0005] It can be seen from the above that the current modified silicone oil system still has many fatal defects, and it still cannot meet the increasingly stringent production and processing requirements.

Abstract

The invention discloses hydrophilic ice-sense silicone oil. The hydrophilic ice-sense silicone oil is characterized by comprising epoxy silane with a side chain-terminal group and having a general formula B, polyether amine having a general formula A, and single amine-terminated polyether having a general formula C; the molar ratio of the epoxy silane with side chain-terminal group, the polyether amine and the single amine-terminated polyether is 1:1:(1-3); the components are subjected to reaction to obtain a mixture of a structural formula I (the formula I is as shown in the description) and a structural formula II (the formula II is as shown in the description) at arbitrary proportion; the n1 of the general formula A is 1-3; the n2 of the general formula B is 1-3; the n3 of the general formula C is 1-3; and m is 1-10. The hydrophilic ice-sense silicone oil provided by the invention can give smooth and fine hand feeling to a fabric, can realize instant hydrophilic action and has strong chemical stability and self-emulsifying function.

Description

technical field [0001] The invention relates to the field of fabric dyeing and finishing auxiliaries, in particular to a hydrophilic ice-feeling silicone oil capable of imparting soft and smooth handles to fabrics and a preparation method thereof. Background technique [0002] At present, amino-modified silicone oil is widely used in the fields of textile finishing and textile dyeing and finishing because of its good chemical reactivity, strong two-phase lubricity and compatibility. Amino-modified silicone oil mainly includes side-chain amino-modified silicone oil and straight-chain block amino-modified silicone oil. Among them, side-chain amino-modified silicone oil has strong molecular chain flexibility, and most of them are hydrophobic additives. After finishing, the silicone oil will stay on the surface of the fabric, and can give the fabric a soft and smooth feel; while the linear block amino-modified silicone oil has a strong group linking ability, and most of them are...
