Problems solved by technology

[0003] However, natural ingredients such as cotton, silk, and hemp fiber have poor antibacterial properties. The growth of bacteria will not only destroy the beauty and practicability of textiles, but also cause serious damage to the human body and pose a threat to human health, thus affecting textiles. It is also necessary to carry out antibacterial treatment, and the combustion-supporting effect of textiles is relatively poor, so it is also necessary to carry out flame-retardant treatment on textiles;

Abstract

The invention discloses an environment-friendly composite textile finishing agent and a preparation method thereof. The preparation method includes adding octamethylcyclotetrasiloxane and potassium hydroxide into a 250 mL dry flask fitted with a rotary condensing tube, a stirrer, a dripping funnel and a thermometer, stirring, heating, dropping N-beta-aminoethyl-gamma-aminopropylmethyldimethoxysilane into the flask through the dripping funnel when liquid temperature rises to 40-60 DEG C, heating to 135 DEG C, holding the temperature of 135-140 DEG C when liquid viscosity rises 0.5 hour later, and allowing to react for 6 hours to obtain a colorless transparent viscous liquid. Organosilicon-polyurethane, a mixed liquid and organosilicon quaternary ammonium salt modified polysiloxane are mixedthrough a mixing device, so that working efficiency is improved, and fusing is better; synergistic effect helps impart good antibacterial, anti-wrinkle, softening, hydrophilic and flame-retarding properties to the finishing agent; the synthetic method herein is simple to perform, causes no environmental pollution and is expectedly suitable for environment-friendly industrial production.

Description

technical field [0001] The invention relates to the technical field of finishing agents, in particular to an environment-friendly composite textile finishing agent and a preparation method thereof. Background technique [0002] Cotton fabric has good hygroscopicity, heat preservation and comfort. Therefore, cotton fabrics are widely welcomed by the public. Due to the characteristics of the cotton fiber structure, when the external force is applied, the molecular chain structure changes, and when the external force is removed, there is not enough binding force between the molecules to return to the original state, which makes the wrinkle resistance of cotton fabrics very poor. Cotton fabric also has inherent defects such as easy to wrinkle, easy to fade, easy to shrink. In order to improve the washability and wearability of fabrics, solve the problem of easy wrinkling, and improve the shape stability and aesthetics of fabrics, it is necessary to carry out anti-wrinkle finis...
