Antiviral Finishing
Antiviral finishing is a process in which chemicals or functional ingredients are applied to reduce the number of specific viruses attached to fibers or textile surfaces.

Definition and Overview
Antiviral finishing is a process that adds functionality to fabric through post-processing and other methods. It evaluates the performance of reducing specific viruses on fibers under test conditions, but it does not guarantee infection prevention for the wearer or treatment of disease.
The target virus, evaluation method, and durability of the effect vary depending on the finishing agent, fabric, and test conditions. When planning, it is important to check not only the functionality you want to promote, but also the test details that support it and the scope of the labeling.
Features and Hand Feel
Processing methods include methods of blending it into the fiber and methods of adding functional agents to the surface of the fabric. The base material can be various types, such as woven fabrics, knits, and nonwovens, and it is not limited to materials such as cotton or polyester.
In many cases, the appearance does not differ greatly from ordinary fabric, but depending on the finishing agent and amount applied, the texture may change in terms of stiffness, slipperiness, water absorbency, and color tone. If necessary, check with samples before and after processing.
Main Applications
It is used for clothing and textile products designed with hygiene considerations as a function. In addition to shirts, innerwear, nightwear, uniforms, and kids' clothing, it is also considered for products used in applications that are frequently touched by hand.
It is not a finishing process limited to a particular season; it is used year-round or by season depending on the thickness, warmth, and breathability of the base material. For summer items, confirm water absorbency and breathability; for fall and winter items, confirm compatibility with a brushed feel and warmth retention.
Selection and Handling Notes
The balance between antiviral performance and appearance or physical properties changes depending on the material, structure, dyeing, and combination with other functional finishes. Select the fabric by checking with the fabric supplier the conditions of the performance test, including after washing, the target virus, and the expressions that can be indicated.
To understand shrinkage, color fading, and changes in finishing performance, conduct washing tests and sewing tests before full production. Because high-temperature drying, strong bleaching processes, and the type of chemicals used may affect performance and hand feel, handling in accordance with the care label is necessary.
Sewing itself can be performed in the same way as with ordinary fabric, but if the surface has slipperiness or stiffness due to the finish, adjust the presser foot pressure, needle, and thread tension. It is also safe to check in advance with a scrap piece for discoloration or fading caused by ironing.
Differences from Similar Terms
Antibacterial deodorizing is a finishing process mainly intended to suppress bacterial growth and the generation of odor. Because it differs from antiviral finishing in the target and evaluation method, even when both functions are present, check the evidence for each performance separately.
Deodorizing finishing is a function that suppresses odor by adsorbing and decomposing odor components, and its purpose differs from antiviral finishing. It may also be used together with finishes such as shrink-resistance or water-repellent finishes that support wash durability and wearing comfort.
Frequently Asked Questions
Can clothing with antiviral finishing prevent infection?
Antiviral finishing is a process intended to reduce specific viruses on fibers under specified test conditions. It does not guarantee infection prevention, prevention of transmission, or therapeutic effects through wearing the garment. For product labeling, please check the test items and the scope that can be indicated.
Does antiviral finishing come off in washing?
Changes in performance due to washing vary depending on the finishing method, base material, detergent, and drying conditions. Some finishes have confirmed wash durability, but performance data including the number of washes and the test method must be checked. For products, follow the care label and avoid excessive bleaching or high-temperature treatment.
Are antibacterial deodorizing finishes and antiviral finishes the same?
No, they are not the same. Antibacterial deodorizing finishes mainly aim to suppress bacterial growth and the generation of odor, while antiviral finishes target specific viruses on fibers. Both functions may be added, but the evaluation targets, test methods, and labeling content must be checked separately.
