Abstract

The invention provides a moisture-absorbing and quick-drying antibacterial composite finishing agent, a preparation method and a use method of the moisture-absorbing and quick-drying antibacterial composite finishing agent. The moisture-absorbing and quick-drying antibacterial composite finishing agent comprises the following components in percentage by weight: 0.5-2.0% of moisture-absorbing and quick-drying function polymer, 0.5-1.0% of nano antibacterial powder, 0.3-1.0% of coupling agent, 0.2-1.0% of superdispersant and 95.5-98.0% of solvent. The preparation method comprises the following steps of: chemically modifying and dispersing the nano antibacterial powder by using the coupling agent and superdispersant to prepare a nano antibacterial agent, wherein one end of the nano antibacterial agent is combined by chemical bonds, and the other end of the nano antibacterial agent has a chemical structure of an active hydrogen group or a reaction group; and reacting chemically-modified nano antibacterial powder with modified polyether organosilicon by using the active hydrogen group or the reaction group on a molecular chain, thereby realizing grafting of the nano antibacterial agent and the moisture-absorbing and quick-drying function polymer. A composite finishing liquor is prepared from the finishing agent, a penetrating agent, a softening agent and soft water and is applied to afterfinish of fabrics, and the functional fabrics with antibacterial property, moisture-absorbing property and quick-drying property can be prepared.

Description

(1) Technical field [0001] The invention relates to the application field of functional textiles, in particular to a finishing agent with antibacterial, moisture-absorbing and quick-drying composite functions, a preparation method and a use method. (2) Background technology [0002] With the improvement of people's living standards, clothing is becoming more and more exquisite, and people have higher and higher requirements for the comfort, health, safety and environmental protection of clothing fabrics. The comfort of the fabric, especially in the case of a lot of sweating, the fabric needs to have the characteristics of fast sweat absorption, fast transmission, and fast evaporation, so that the human body can feel the comfort of internal and external dryness and instant quick drying, that is, the fabric must have With the function of moisture absorption and quick drying, if it is in an environment with high humidity and high temperature, and in the case of a lot of sweatin...
