Influence of fabrics on sun protection properties
1
Fabric thickness and porosity
The thicker the thickness, the closer the structure, the smaller the corresponding porosity, the better the UV protection effect of the fabric.
But to bask in garment fabric, want to ensure already light and thin this one characteristic above all, can consider dense, pore small fabric.
2
Color of fabric
Color is another important factor affecting the UV protection performance of the fabric. After dyeing, the fabric contains some dye molecules, and the groups on the dye molecules will enhance the absorption of ultraviolet rays.
The higher the purity, the better the ability to absorb ultraviolet rays, so you can choose relatively dark color sunscreen clothing preferentially.
Comfort requirements for sunscreen clothing
1
Breathability
Breathability refers to the performance of gas through the fabric, which directly affects the thermal and wet comfort of sunscreen clothing.
Prevent sunscreen clothing to wear in summer, ask its to have good air permeability, ability quickly loses heat, avoid sultry.
2
Moisture permeability
It is an important index to evaluate the comfort of sunscreen clothing.
Summer day, people produces certain heat and sweat, ask clothes to have good wet permeability, avoid people to produce sultry feeling, sticky feeling when wearing.
Attention
Vol.1/ Poor UV protection
The UV protection processing technology and fabric structure of sunscreen clothing are unreasonable, which can not meet the standard requirements. The UV protection coefficient UPF value is lower than 40 or UVA transmission T (UVA) AV is greater than 5%. Wearing in the hot sun for a long time will not have a sunscreen effect, which can easily lead to skin sunburn and even cause other skin diseases.
Vol.2/ Fiber composition or content not consistent with labeling
The actual fiber content of sunscreen clothing is inconsistent with the fiber content of the product. The false label and wrong label of fiber composition are easy to mislead consumers. The inferior fiber material is easy to cause no sweat absorption, air tightness, and induce skin itching.
Vol.3/ Label description is not standard
Label description is not standard, including: The UV protection performance standard is not marked; Uv protection performance indicators, such as the UPF value, are not marked. The origin, the name and address of the agent or importer or seller are not completely marked.
Label is an important source of information when consumers choose and buy products, and also an important basis for consumer rights protection.
