Abstract

The present invention discloses a smooth and elastic finishing agent for nylon-cotton fabrics, and a preparation method thereof. The smooth and elastic finishing agent for nylon-cotton fabrics is prepared by the following components in weight percentage: 30-45% of modified terpolymer block silicone oil, 10-20% of isomeric fatty alcohol-polyoxyethylene ether, 0.05-2.5% of glacial acetic acid and 35-55% of water. According to the technical scheme of the invention, the synthesis of end epoxy silicone oil is conducted according to the alkali process route, so that the generation of a large amount of solid waste residues is avoided. Meanwhile, the method is simple in process, and the end epoxy silicone oil can be obtained in one step. Moreover, an obtained product is better in sliding feeling and delicate feeling compared with products obtained through the conventional acid method.

Description

[0001] Technical field: [0002] The invention relates to a finishing agent for textiles, in particular to a slippery finishing agent for nylon-cotton fabrics and a preparation method and application thereof. [0003] Background technique: [0004] With the continuous development of the silicone industry and the improvement of people's living standards, the polysiloxane finishing agent modified by a single active group cannot meet people's needs because of its specificity for fabric finishing and its existing defects. Demand, such as the fabric finished with amino silicone oil, although it has good softness and smooth hand feeling, it has poor hygroscopicity and is prone to yellowing; while the fabric finished with polyether modified silicone oil has better hydrophilic air permeability and improved antistatic property , can improve the shortcomings of the fabric when it is stuffy, easy to be charged with static electricity, and dust-absorbing, but the softness and durability wi...
