Abstract

The invention relates to a multifunctional finishing agent based on hyperbranched polyester derivative as well as preparation and application thereof. The finishing agent is prepared from a hyperbranched polyester derivative solution for wrapping a functional agent. The preparation comprises the steps: preparing the hyperbranched polyester derivative solution; then adding the functional agent, stirring and dispersing to make the functional agent permeate into an inner cavity of the polyester to form a functional compound and preparing into a mixed solution; dipping or padding the polyester fabric by the solution and performing pre-baking and baking treatment. The multifunctional finishing agent disclosed by the invention has the advantages that a finishing method is easy and practical to operate, raw materials and a technological process are friendly to the environment and the human body, and a padding and baking mode is utilized to finish hyperbranched polyester and the functional agent to the fabric; thus, not only are moisture absorption and quick dryness of the polyester fabric enhanced, but also the fabric has effects of intelligently adjusting temperature, resisting bacteria,retarding flame, resisting static electricity and the like; furthermore, the polyester fabric has excellent washing resistance, and requirements of people for multifunctional fabrics are met.

Description

technical field [0001] The invention belongs to the field of fabric finishing agents and their preparation and application, in particular to a multifunctional finishing agent based on hyperbranched polyester derivatives and its preparation and application. Background technique [0002] Polyester fabric is more and more widely used in clothing fabrics because of its good strength, abrasion resistance, stiffness and dimensional stability. However, polyester is a typical hydrophobic fiber, and the moisture regain in the standard state is only It is 0.4%, its moisture absorption and moisture permeability are poor, it is easy to generate static electricity and stains, and its wearing comfort is worse than that of natural fibers. [0003] With the improvement of people's living standards, people tend to develop in the direction of comfort, hygiene, environmental protection and other multi-functional, high-functional and composite functions for the functions of fabrics. In order t...
