As the functional requirements of fabrics become higher and higher, a variety of functional textile fabrics are emerging in an endless stream, such as flame retardant fabric, anti-ultraviolet fabric, three-way fabric, sweat absorbent fabric, warm and cool fabric and antibacterial fabric.

Some functions are achieved by finishing textiles such as dipping processes, and some are achieved by applying a coating on the surface of the textile fabric, proportional flame retardant coating, UV protection coating, antibacterial coating. Among them, antibacterial coating is a kind of emerging in recent years, which can be applied to tablecloths, curtain fabrics, etc. This antibacterial coating has the function of killing bacteria and inhibiting bacterial growth. Previously, due to the COVID-19 and other factors, this kind of textile fabric with antibacterial function has been favored by consumers.

Antibacterial textile coating is to add antibacterial ingredients in the material, according to different uses and requirements, there are many types of antibacterial textile coating materials.

First, antibacterial textile coating types introduced

1, antibacterial PA coating

PA coating, Polyacrylate fabric coating glue (Polyacrylate referred to as PA), also known as AC glue coating, namely acrylic coating, is the most common and common kind of coating at present, which can increase hand feel, windproof and sag after painting. It is often used for anti - velvet, feel, color fixing and sand fixing.

2, antibacterial PU coating

Polyurethane coating (PU for short), full known as polyurethane ester, the coated fabric has fullness, elasticity and film sense. Coating soft and elastic, good strength, good moisture permeability and ventilation properties, and can be made very thin coating.

3, antibacterial and anti-velvet coating

Also called anti-down coating, after coating can prevent down running down, suitable for down jacket fabric.

4, antibacterial white glue coating

5, antibacterial silver glue coating

Namely on the surface of the fabric coated with a layer of silver glue, so that the fabric has the function of shading, imitation radiation, generally used in curtains, tents, clothing.

6, antibacterial oily coating

Coated surface smooth and glossy, family daily use, generally applicable to do tablecloth.

Two, textile coating antibacterial agent selection

The selection of antibacterial agents for textile coating should be targeted according to the different coating material system, textile environment and antibacterial requirements. Such as water-based PA, PU and solvent coating antibacterial agents are different, in addition if the textile fabric is applied in the outdoor such as tents, to use UV resistant antibacterial agents such as thiazole, otherwise improper selection of antibacterial agents will lead to fabric in the late use of discoloration problems, affecting the appearance.

Some textile fabrics are used in a humid environment for a long time, so they require antibacterial, mildew and algal resistance at the same time. Such coatings generally choose organic antibacterial agents. General contact with the human body and high safety requirements, through the use of silver ion antibacterial agents. Therefore, the selection of textile coating antibacterial agent should be based on the specific coating formulation, use environment and antibacterial requirements.
