Color fastness, PH value

1. Color fastness

Although there is not enough evidence to prove that all the dyes used in China polyester shade fabrics are harmful to humans, it is certain that strengthening the color fastness of dyed rolling blind fabrics can reduce their possible harm.

Therefore, it is also necessary to pay attention to the color fastness of the China sunshade fabrics.

2.PH value

The surface layer of human skin is acidic, which can inhibit the propagation of various germs.

Therefore, it is beneficial to human health to control the PH value on the motorized blind shade fabric to be neutral or weakly acidic.

If the PH value is too high or low, it may cause allergies, and it may cause skin ulcers, which may cause other diseases.

Oeko-tex100 stipulates that the China windows sunscreen fabric shade fabric that does not directly contact the skin has a surface PH value of 4.0-9.0

3.Odor detection

In the production and processing of shade fabrics, some odorous substances are introduced more or less. The generation of these odors comes from the chemical finishing agents and additives used in the processing. The presence of odors means that too many chemicals remain on the fabric, Causing damage to the human body.

Therefore, environmental protection and ecological shade fabrics must not have various pungent odors such as musty smell.

In addition to the above conventional monitoring items, the chemicals and raw materials included in the monitoring scope include organic tin compounds, insect repellent finishing agents, chlorine-containing or flame-retardant agents, chlorine-containing bleaching agents, and volatile organic compounds.
