Antibacterial and easy to decontaminate
The easy-to-decontaminate functional finishing is mainly to form a hydrophilic functional film with moisture permeability, breathability, dust resistance, and scale inhibition on the surface of the fiber. Its components are composed of polyacrylates, polyurethanes, silicones, organic fluorines, etc. The agent is made in different proportions.
1. In principle, the selection of additives requires five aspects of antibacterial agents: safety, high efficiency, broad spectrum, durability, compatibility and compatibility, and no negative impact on the performance of taking. There are many types of antibacterial agents that meet the above requirements and performance It is different from antibacterial mechanism. At present, DC-700, SCJ series and nano inorganic materials are more commonly used.
2. Process formula (1) Prescription: antibacterial agent 1.0 ~ 4.0 (OWf); easy decontamination finishing agent 1.5% ~ 6.0% (0Wf).
(2) Process conditions: dip-rolling working fluid (rolling rate 80%, two-dip and two-roll), drying (90 ~ i00 ℃) and baking (130 ~ 160 ℃, 2 ~ 5min).
3. Analysis and discussion (1) Inorganic nanomaterials are divided into two types according to the antibacterial mechanism, one is the type of contact reaction, such as Ag, cu, zn and their ionic oxides or composites; the other is the type of photocatalytic reaction, such as nm — Ti02 / ZnO, etc.
(2) The high-priced Ag ion antibacterial effect is large, and the Ag ion antibacterial mechanism has both the above two types. In water, the concentration of Ag ions is 0.05mg / L, which can kill E. coli.
(3) nm—Ti02 / ZnO generates electrons and holes under the excitation of light energy, both of which cause the surface 0z and H20 to become superoxide anion free radicals 0z and hydroxyl radicals, thereby decomposing polluted organic matter and killing bacteria.
(4) Similar to the principle of nanomaterial interface modification, the functional finishing of natural fibers is essentially the modification process of the interface. The difference is that this modification is completed under the macroscopic state of the fiber material. The finishing agent is mainly a polymer compound; through comparative analysis, we have summarized a theoretical model for functional finishing-multiple composite modification of the fiber interface: through the combination of compound materials with different characteristics such as polyurethane, organic fluorine, silicone, polyacrylates and Nanomaterials, etc., are compounded at the interface of the fiber material to increase, improve or modify the application characteristics and functions of the fiber material.
