"Hard sunscreen" clothing fabrics such as sunscreen clothing and sunscreen masks not only need to have good UV resistance, but their breathability is also an important indicator to measure the performance of wearing. In particular, the breathability of the fabric of sunscreen masks is directly related to the wearer's wearing experience. Therefore, when developing the UV resistance function of sunscreen mask fabrics, it is necessary to ensure that the finishing process does not affect its original breathability.
The anti-ultraviolet finishing process of the fabric mainly includes printing method, coating method and dipping method:
1) Stamp method
The printing method has a low cost, but the protective effect is limited, and the processed fabrics have weak UV resistance, which is suitable for textiles with low requirements for ultraviolet protection;
2) Coating method
The fabrics processed by the coating method have good UV resistance, but will affect the washing fastness and hand feel of the fabric, and are usually used in decorative and technical textiles.
3) Immersion method
The dipping method is more common in the anti-ultraviolet finishing of fabrics, and this processing technology can give light and thin fabrics excellent anti-ultraviolet ability, which is suitable for the development of anti-ultraviolet function of sunscreen clothing.
In the dipping process, the choice of additives is crucial. Taking Texnology®UV Pro as an example, this kind of organic UV absorber has good process applicability, which can significantly improve the UV protection effect of the fabric without affecting the color, breathability, fiber strength and other indicators of the sunscreen mask fabric, and bring more flexible design options for sunscreen mask products.
Through reasonable process parameters and dosage control, the sunscreen mask fabric can achieve the excellent ultraviolet protection index of ultraviolet protection coefficient (UPF) greater than 40 and the average UVA projection ratio (T(UVA)AV) less than 5%, in line with the standard of GB/T 18830-2009 "Evaluation of Ultraviolet Protection Performance of Textiles", providing wearers with a safe and comfortable sunscreen experience.
