The UV resistance of dyed fabrics mainly depends on factors such as fiber type, dyeing method, and chemical additives.
The influence of fiber type on the UV resistance of dyed fabrics
The UV resistance of different fibers varies significantly. For example, polyester (polyester fiber) has good UV resistance, but its thermal and moisture comfort is poor; cotton fibers have weak UV resistance but good breathability. In addition, blended fabrics such as polyester/cotton blend fabrics have better UV protection performance than pure cotton fabrics.
The influence of dyeing methods on the UV resistance of dyed fabrics
The dyeing method can also affect the UV resistance of fabrics. Ordinary fibers, yarns, and fabrics themselves have a certain degree of UV protection ability, but most of them cannot achieve the daily sun protection effect required. Therefore, UV shielding agents can be used to chemically treat fibers or fabrics, enhancing their UV resistance by reflecting or absorbing UV radiation.
The influence of chemical additives on the UV resistance of dyed fabrics
Chemical additives play an important role in the dyeing process. UV shielding agents can be divided into two types: Organic and inorganic. Organic shielding agents absorb UV radiation and convert it into low-energy release, while inorganic shielding agents achieve their shielding effect by reflecting UV radiation. The use of these additives can significantly improve the UV resistance of dyed fabrics.
